　従来、移動体の乗り心地を向上するために、乗員の姿勢を検出し、乗員の姿勢に応じて、シートクッションやシートバックを制御することで、乗員の姿勢をサポートするシート装置が知られている（特許文献１）。 Conventionally, there has been known a seat device that supports the occupant's posture by detecting the occupant's posture and controlling the seat cushion and the seat back according to the occupant's posture in order to improve the riding comfort of the moving body. (Patent Document 1).
特開２００６－８０９８号公報JP 2006-8098 A
　従来技術は、乗員の姿勢をサポートすることで、車両の走行により乗員に加わる運動負荷（車両の走行時に乗員が姿勢を保つために必要な筋肉負荷）を軽減させるものであるため、車両走行中に、乗員が健康の維持・向上ために必要な運動量を得ることは困難であった。 The conventional technology reduces the exercise load applied to the occupant by traveling the vehicle (muscle load necessary for the occupant to maintain the posture when the vehicle travels) by supporting the occupant's posture. In addition, it was difficult for passengers to obtain the amount of exercise necessary to maintain and improve their health.
　本発明が解決しようとする課題は、それぞれの乗員に適した受動運動をそれぞれの乗員に行わせることが可能な車載シート装置の制御装置を提供することである。 The problem to be solved by the present invention is to provide a control device for an in-vehicle seat device capable of causing each occupant to perform a passive motion suitable for each occupant.
　本発明は、乗員の受動運動による運動量が変化するように、乗員の姿勢を変化させるための受動運動機構を備えた車載シート装置の制御装置において、受動運動機構の制御が行われている際の乗員の姿勢、または、車載シート装置に着座した乗員の身体状態を検出する身体状態を検出し、受動運動機構を駆動させる際に、検出された乗員の姿勢または身体状態に基づいて、受動運動機構の駆動量を調整することで、上記課題を解決する。 The present invention relates to a control device for an in-vehicle seat device having a passive motion mechanism for changing the posture of an occupant so that the amount of motion due to the passive motion of the occupant changes. The passive motion mechanism is detected based on the detected posture or body state of the occupant when detecting the posture of the occupant or the physical state of the occupant seated on the in-vehicle seat device and driving the passive motion mechanism. The above-mentioned problem is solved by adjusting the driving amount.
　本発明によれば、受動運動機構により変化した乗員の姿勢、または、車載シート装置に着座した乗員の身体状態に基づいて受動運動機構の駆動量を調整することで、乗員の姿勢を受動運動に適した姿勢とすることができ、その結果、乗員に受動運動を適切に行わせることができる。 According to the present invention, the posture of the occupant is changed to the passive motion by adjusting the driving amount of the passive motion mechanism based on the posture of the occupant changed by the passive motion mechanism or the physical state of the occupant seated on the in-vehicle seat device. A suitable posture can be obtained, and as a result, the occupant can appropriately perform passive exercise.

　≪第１実施形態≫
　以下、本発明の実施の形態を図面に基づいて説明する。 << First Embodiment >>
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　本実施形態においては、車両に搭載されるシート装置の制御システムを例示して説明する。ここで、図１は、本実施形態に係るシート装置の制御システムを備えた車両１（以下、自車両１ともいう）の構成を示すブロック図である。図１に示すように、車両１は、シート装置１００と、姿勢検出装置２００と、制御装置３００と、データベース４００とを有する。これらの装置は、ＣＡＮ（Controller Area Network）その他の車載ＬＡＮによって接続され、相互に情報の授受を行う。 In the present embodiment, a control system for a seat device mounted on a vehicle will be described as an example. Here, FIG. 1 is a block diagram illustrating a configuration of a vehicle 1 (hereinafter, also referred to as a host vehicle 1) provided with a control system for a seat device according to the present embodiment. As shown in FIG. 1, the vehicle 1 includes a seat device 100, an attitude detection device 200, a control device 300, and a database 400. These devices are connected by a CAN (Controller Area Network) or other vehicle-mounted LAN, and exchange information with each other.
　図２は、本実施形態に係るシート装置１００を示す図である。本実施形態に係るシート装置１００は、車両１に搭載され、車両１に乗車した乗員が着座可能となっている。また、以下に説明するシート装置１００は、運転者が着座する運転席のシート装置に適用してもよいし、あるいは、運転者以外の同乗者が着座する席のシート装置に適用してもよい。 FIG. 2 is a view showing the sheet apparatus 100 according to the present embodiment. A seat device 100 according to the present embodiment is mounted on a vehicle 1 so that an occupant riding the vehicle 1 can be seated. The seat device 100 described below may be applied to a seat device in a driver seat where a driver is seated, or may be applied to a seat device in a seat where a passenger other than the driver is seated. .
　図２に示すように、シート装置１００は、乗員がシート装置１００に着座した際に、乗員の下半身を支持するシートクッション１０と、乗員の上体を支持するシートバック２０と、乗員の頭部を支持するヘッドレスト３０とから構成される。 As shown in FIG. 2, when the occupant sits on the seat device 100, the seat device 100 includes a seat cushion 10 that supports the lower body of the occupant, a seat back 20 that supports the upper body of the occupant, and the head of the occupant. It is comprised from the headrest 30 which supports.
　シートバック２０には、図２に示すように、胸椎部エアバック２１および腰椎部エアバック２２が設けられている。具体的には、胸椎部エアバック２１は、乗員がシートバック２０に寄りかかった際に、乗員の胸椎に対応する位置に設けられており、腰椎部エアバック２２は、乗員がシートバック２０に寄りかかった際に、乗員の腰椎に対応する位置に設けられている。 The seat back 20 is provided with a thoracic vertebra airbag 21 and a lumbar airbag 22 as shown in FIG. Specifically, the thoracic portion airbag 21 is provided at a position corresponding to the thoracic vertebra of the occupant when the occupant leans against the seat back 20, and the lumbar portion airbag 22 is disposed on the seat back 20. It is provided at a position corresponding to the lumbar spine of the occupant when leaning.
　また、胸椎部エアバック２１は、ホース４１を介してエアポンプ４０と接続している。そして、エアポンプ４０により、胸椎部エアバック２１内に空気を送り込み、あるいは、胸椎部エアバック２１内から空気を排出することで、胸椎部エアバック２１の形状が可変となっている。同様に、腰部部エアバック２２は、ホース４２を介してエアポンプ４０と接続されており、エアポンプ４０により腰椎部エアバック２２内に空気を送り込み、あるいは腰椎部エアバック２２内から空気を排出することで、腰椎部エアバック２２の形状が可変となっている。 In addition, the thoracic spine airbag 21 is connected to the air pump 40 via the hose 41. The shape of the thoracic vertebra part airbag 21 is variable by sending air into the thoracic vertebra part airbag 21 or discharging air from the thoracic part airbag 21 by the air pump 40. Similarly, the lumbar portion airbag 22 is connected to the air pump 40 via the hose 42, and air is sent into the lumbar portion airbag 22 by the air pump 40 or air is discharged from the lumbar portion airbag 22. Thus, the shape of the lumbar portion airbag 22 is variable.
　たとえば、エアポンプ４０により胸椎部エアバック２１内に空気が供給されると、胸椎部エアバック２１は膨らみ、乗員方向（Ｘ軸方向）に突出する。ここで、図３は、乗員がシート装置１００に着座している際における、エアポンプ４０により供給される空気供給量と、胸椎部エアバック２１の突出量との関係の一例を示す図である。また、図３においては、エアポンプ４０により供給される空気供給量と、胸椎部エアバック２１内の空気圧との関係の一例も示している。たとえば、図３に示す例では、エアポンプ４０から胸椎部エアバック２１に対して空気の供給が開始されると、胸椎部エアバック２１が乗員方向（Ｘ軸方向）に突出し始める。これにより、突出した胸椎部エアバック２１が乗員の身体の一部をＸ軸方向に押すこととなり、その結果、車両走行中における乗員の受動運動による運動量が増大するように乗員の姿勢を変化させることができる。なお、図３に示す例では、エアポンプ４０による空気供給量が所定量Ｑｐを超えると、乗員の身体によって胸椎部エアバック２１が押し返されることで、胸椎部エアバック２１の突出が抑制され、胸椎部エアバック２１内の空気圧が高くなる。すなわち、エアポンプ４０からの空気供給量に対して、胸椎部エアバック２１が乗員方向（Ｘ軸方向）に突出する割合が小さくなり、胸椎部エアバック２１内の空気圧が増加する割合が大きくなる。 For example, when air is supplied into the thoracic spine airbag 21 by the air pump 40, the thoracic spine airbag 21 swells and protrudes in the occupant direction (X-axis direction). Here, FIG. 3 is a diagram illustrating an example of a relationship between the air supply amount supplied by the air pump 40 and the protrusion amount of the thoracic vertebra part airbag 21 when the occupant is seated on the seat device 100. FIG. 3 also shows an example of the relationship between the air supply amount supplied by the air pump 40 and the air pressure in the thoracic vertebra airbag 21. For example, in the example shown in FIG. 3, when the supply of air from the air pump 40 to the thoracic vertebra part airbag 21 is started, the thoracic vertebra part airbag 21 starts to protrude in the occupant direction (X-axis direction). As a result, the protruding thoracic vertebra airbag 21 pushes a part of the occupant's body in the X-axis direction, and as a result, the posture of the occupant is changed so that the momentum due to the passive movement of the occupant during vehicle travel increases. be able to. In the example shown in FIG. 3, when the air supply amount by the air pump 40 exceeds a predetermined amount Qp, the thoracic portion airbag 21 is pushed back by the occupant's body, thereby suppressing the protrusion of the thoracic portion airbag 21. The air pressure in the thoracic spine airbag 21 is increased. That is, the rate at which the thoracic portion airbag 21 projects in the occupant direction (X-axis direction) with respect to the amount of air supplied from the air pump 40 decreases, and the rate at which the air pressure within the thoracic portion airbag 21 increases.
　同様に、エアポンプ４０により腰椎部エアバック２２内に空気が供給されると、腰椎部エアバック２２は膨らみ、乗員方向（Ｘ軸方向）に突出し始める。これにより、突出した腰椎部エアバック２２が乗員の身体の一部をＸ軸方向に押すこととなり、その結果、車両走行中における乗員の受動運動による運動量が増大するように乗員の姿勢を変化させることができる。 Similarly, when air is supplied into the lumbar airbag 22 by the air pump 40, the lumbar airbag 22 swells and begins to protrude in the occupant direction (X-axis direction). As a result, the protruded lumbar portion airbag 22 pushes a part of the occupant's body in the X-axis direction, and as a result, the occupant's posture is changed so that the momentum due to the passive movement of the occupant during vehicle travel increases. be able to.
　すなわち、胸椎部エアバック２１や腰椎部エアバック２２を乗員方向（Ｘ軸方向）に突出させることで、乗員の上体とシートバック２０との接触面積は小さくなる。そのため、胸椎部エアバック２１や腰椎部エアバック２２を乗員方向（Ｘ軸方向）に突出させた状態で、車両１が車線変更やカーブ走行を行った場合、その遠心力により、乗員の上体が横方向（略Ｙ軸方向）に動き易くなり、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）を増加させることができる。また、本実施形態においては、後述する制御装置３００の制御により、胸椎部エアバック２１や腰椎部エアバック２２の突出量を自由に調整することができ、胸椎部エアバック２１や腰椎部エアバック２２の突出量に応じて、乗員の受動運動における運動量を調整することができる。 That is, by projecting the thoracic vertebra airbag 21 and lumbar airbag 22 in the occupant direction (X-axis direction), the contact area between the upper body of the occupant and the seat back 20 is reduced. Therefore, when the vehicle 1 changes lanes or runs a curve with the thoracic vertebra airbag 21 or lumbar airbag 22 protruding in the occupant direction (X-axis direction), the upper body of the occupant is caused by the centrifugal force. Becomes easier to move in the lateral direction (substantially in the Y-axis direction), and the exercise load (muscle load) necessary for the occupant to maintain the posture can be increased. In the present embodiment, the amount of protrusion of the thoracic vertebra airbag 21 and lumbar airbag 22 can be freely adjusted by the control of the control device 300 to be described later, and the thoracic airbag 21 and lumbar airbag. The amount of exercise in the passive movement of the occupant can be adjusted according to the amount of protrusion 22.
　なお、本実施形態に係るシート装置１００においては、胸椎部エアバック２１と腰椎部エアバック２２とを同時に突出させることも、あるいは、胸椎部エアバック２１および腰椎部エアバック２２のうちいずれか一方のみを突出させることも可能である。たとえば、胸椎部エアバック２１および腰椎部エアバック２２を同時に突出させた場合には、胸椎部エアバック２１および腰椎部エアバック２２のうちいずれか一方のみを突出させた場合と比べて、乗員の受動運動による運動量をより増大させることができる。 In the seat device 100 according to the present embodiment, the thoracic portion airbag 21 and the lumbar portion airbag 22 may be projected at the same time, or one of the thoracic portion airbag 21 and the lumbar portion airbag 22. It is also possible to protrude only. For example, when the thoracic portion airbag 21 and the lumbar portion airbag 22 are projected at the same time, compared to the case where only one of the thoracic portion airbag 21 and the lumbar portion airbag 22 is projected, the occupant's The amount of exercise by passive exercise can be further increased.
　また、胸椎部エアバック２１や腰椎部エアバック２２が乗員側（Ｘ軸方向）に突出している場合に、エアポンプ４０によって胸椎部エアバック２１や腰椎部エアバック２２内から空気を排出することで、胸椎部エアバック２１や腰椎部エアバック２２の突出量を小さくすることができる。たとえば、胸椎部エアバック２１や腰椎部エアバック２２の突出量をゼロにした場合、乗員の上体とシートバック２０との接触面積は大きくなり、乗員の上体をシートバック２０全体でサポートすることができるため、車両が走行している際に乗員の上体が横方向（Ｙ軸方向）に動き難くなり、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）を減少させることができる。 Further, when the thoracic vertebra airbag 21 or the lumbar vertebra airbag 22 protrudes toward the passenger (X-axis direction), the air pump 40 discharges air from the thoracic vertebra airbag 21 or lumbar airbag 22. The protruding amount of the thoracic vertebra part airbag 21 and the lumbar part airbag 22 can be reduced. For example, when the protrusion amount of the thoracic vertebra part airbag 21 and the lumbar part airbag 22 is set to zero, the contact area between the occupant's upper body and the seat back 20 is increased, and the occupant's upper body is supported by the entire seat back 20. Therefore, when the vehicle is running, the upper body of the occupant becomes difficult to move in the lateral direction (Y-axis direction), and the exercise load (muscle load) necessary for the occupant to maintain the posture is reduced. Can do.
　また、図２に示すように、シートクッション１０には、座面後方部エアバック１１が設けられている。具体的には、座面後方部エアバック１１は、シートクッション１０の中央またはシートクッション１０の中央よりも後方側（Ｘ軸負方向側）であって、乗員がシートクッション１０に着座した際に乗員の臀部に対応する位置に設けられている。 Further, as shown in FIG. 2, the seat cushion 10 is provided with a seat surface rear portion airbag 11. Specifically, the seat surface rear portion airbag 11 is located behind the center of the seat cushion 10 or the center of the seat cushion 10 (X-axis negative direction side), and when the occupant sits on the seat cushion 10 It is provided at a position corresponding to the occupant's buttocks.
　座面後方部エアバック１１は、ホース４３を介してエアポンプ４０と接続されており、エアポンプ４０により座面後方部エアバック１１内に空気を送り込み、あるいは座面後方部エアバック１１内から空気を排出することで、座面後方部エアバック１１の形状は可変となっている。 The seat surface rear part airbag 11 is connected to the air pump 40 via the hose 43, and air is sent into the seat surface rear part airbag 11 by the air pump 40, or air is sent from the seat surface rear part airbag 11. By discharging, the shape of the seat surface rear portion airbag 11 is variable.
　たとえば、エアポンプ４０により座面後方部エアバック１１内に空気が供給されると、座面後方部エアバック１１は膨らみ、乗員方向（Ｚ軸方向）に突出する。そして、このように座面後方部エアバック１１を乗員方向（Ｚ軸方向）に突出させることで、乗員の下半身とシートクッション１０との接触面積が小さくなり、これにより、車両が車線変更やカーブ走行を行った際の遠心力や、車両が加速または減速した際の慣性力により、乗員の身体が前後左右（Ｘ軸方向、Ｙ軸方向）に動き易くなり、車両走行中において、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）を増加させることができる。このように、本実施形態に係るシート装置１００は、座面後方部エアバック１１を乗員方向（Ｚ軸方向）に突出させることで、車両の運動エネルギーを利用した乗員の受動運動における運動量を増大させることができる。 For example, when air is supplied into the seat surface rear portion airbag 11 by the air pump 40, the seat surface rear portion airbag 11 expands and protrudes in the passenger direction (Z-axis direction). And by making the seat surface rear part airbag 11 project in the occupant direction (Z-axis direction) in this way, the contact area between the lower body of the occupant and the seat cushion 10 is reduced, which allows the vehicle to change lanes or curve The occupant's body is easy to move back and forth and left and right (X-axis direction and Y-axis direction) due to the centrifugal force when traveling and the inertial force when the vehicle accelerates or decelerates. It is possible to increase the exercise load (muscle load) necessary for maintaining the balance. As described above, the seat device 100 according to the present embodiment increases the momentum in the passive motion of the occupant using the kinetic energy of the vehicle by causing the seat surface rear portion airbag 11 to protrude in the occupant direction (Z-axis direction). Can be made.
　一方、座面後方部エアバック１１が乗員側に突出している場合に、エアポンプ４０により座面後方部エアバック１１内から空気を排出することで、座面後方部エアバック１１の突出量を小さくすることができる。たとえば、座面後方部エアバック１１の突出量をゼロにした場合、乗員の下半身とシートクッション１０との接触面積は大きくなり、シートクッション１０において乗員の下半身の体圧分布が等しくなるように、乗員の下半身をシートクッション１０全体でサポートすることができる。そのため、自車両１が走行している際に、乗員の身体が前後左右（Ｘ軸方向、Ｙ軸方向）に動き難くなり、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）を減少させることができる。なお、本実施形態においては、後述する制御装置３００の制御により、座面後方部エアバック１１の突出量を自由に調整することができ、座面後方部エアバック１１の突出量に応じて、乗員の受動運動による運動量を調整することができる。 On the other hand, when the seat back portion airbag 11 protrudes toward the occupant side, the air pump 40 discharges air from the seat back portion airbag 11 to reduce the protrusion amount of the seat back portion airbag 11. can do. For example, when the protrusion amount of the seat back portion airbag 11 is set to zero, the contact area between the lower body of the occupant and the seat cushion 10 is increased, and the body pressure distribution of the lower body of the occupant is equal in the seat cushion 10. The lower body of the occupant can be supported by the entire seat cushion 10. Therefore, when the host vehicle 1 is traveling, the occupant's body is difficult to move back and forth, left and right (X-axis direction, Y-axis direction), and the exercise load (muscle load) necessary for the occupant to maintain the posture is increased. Can be reduced. In the present embodiment, the amount of protrusion of the seat surface rear portion airbag 11 can be freely adjusted by the control of the control device 300 described later, and according to the amount of protrusion of the seat surface rear portion airbag 11, The amount of exercise by passive movement of the occupant can be adjusted.
　加えて、シートクッション１０には、図２に示すように、一対の座面前方部エアバック１２，１３が設けられている。具体的には、一対の座面前方部エアバック１２，１３は、シートクッション１０の中央よりも前方（Ｘ軸正方向側）であって、乗員がシートクッション１０に着座した際に乗員の左右大腿部にそれぞれ対応する位置に設けられている。 In addition, as shown in FIG. 2, the seat cushion 10 is provided with a pair of seat surface front portion airbags 12 and 13. Specifically, the pair of seat surface front portion airbags 12 and 13 are in front of the center of the seat cushion 10 (X-axis positive direction side), and when the occupant is seated on the seat cushion 10, It is provided at a position corresponding to each thigh.
　座面前方部エアバック１２，１３は、ホース４４，４５を介してエアポンプ４０と接続している。そして、エアポンプ４０により座面前方部エアバック１２，１３内に空気を送り込み、あるいは座面前方部エアバック１２，１３内から空気を排出することで、座面前方部エアバック１２，１３の形状が可変となっている。 The seat front portion airbags 12 and 13 are connected to the air pump 40 via hoses 44 and 45. Then, the air pump 40 feeds air into the seat front part airbags 12 and 13, or discharges air from the seat front part airbags 12 and 13, thereby forming the shape of the seat front part airbags 12 and 13. Is variable.
　ここで、図４は、第１実施形態に係るシート装置１００の側面を示す（Ｙ軸方向から見たシート装置１００を示す）概要図であり、図４（Ａ）は、座面前方部エアバック１２，１３に十分な量の空気が供給されている場面のシート装置１００を示しており、図４（Ｂ）は、座面前方部エアバック１２，１３内から十分な量の空気を排出した場面のシート装置１００を示している。 Here, FIG. 4 is a schematic view showing the side surface of the seat device 100 according to the first embodiment (showing the seat device 100 viewed from the Y-axis direction), and FIG. FIG. 4B shows the seat apparatus 100 in a scene where a sufficient amount of air is supplied to the backs 12 and 13, and FIG. 4B discharges a sufficient amount of air from the seat front part airbags 12 and 13. The sheet apparatus 100 of the scene which carried out is shown.
　たとえば、図４（Ａ）に示すように、座面前方部エアバック１２，１３内に十分な量の空気が供給されている場合、座面前方部エアバック１２，１３は膨らみ、乗員方向（略Ｚ軸方向）に突出する。このように、座面前方部エアバック１２，１３内に十分な量の空気が供給されている場合には、座面前方部エアバック１２，１３が乗員方向（略Ｚ軸方向）に突出することで、シートクッション１０の座面を略水平とすることができる。これにより、車両走行時における乗員の運動負荷（筋肉負荷）が軽減し、乗員が運転を適切に行うことができる。 For example, as shown in FIG. 4 (A), when a sufficient amount of air is supplied into the seat front part airbags 12 and 13, the seat front part airbags 12 and 13 are inflated and occupant direction ( It projects in the direction of the substantially Z axis). Thus, when a sufficient amount of air is supplied into the seat front part airbags 12 and 13, the seat front part airbags 12 and 13 protrude in the occupant direction (substantially Z-axis direction). Thereby, the seat surface of the seat cushion 10 can be made substantially horizontal. Thereby, the exercise | movement load (muscle load) of a passenger | crew at the time of vehicle travel is reduced, and a passenger | crew can perform a driving | operation appropriately.
　これに対して、図４（Ｂ）に示すように、座面前方部エアバック１２，１３内から十分な量の空気を排出させた場合、座面前方部エアバック１２，１３の乗員方向（略Ｚ軸方向）への突出量はゼロとなる。そのため、図４（Ｂ）に示すように、シートクッション１０の座面は全体的に前方（Ｘ軸方向）に傾くことなる。このように、シートクッション１０の座面が前方に傾いている場合、このシートクッション１０に着座する乗員の姿勢も前方（Ｘ軸方向）に傾くため、たとえば、車両が加速または減速した際の慣性力により、乗員の身体が前後方向（Ｘ軸方向）に動き易くなり、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）を増加させることができる。特に、乗員がシートバック２０に寄りかからないように、乗員の姿勢を前方に傾けることで、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）をより増加させることができる。このように、本実施形態に係るシート装置１００は、座面前方部エアバック１２，１３内から空気を排出させて、シートクッション１０の座面を前方に傾けることで、車両の運動エネルギーを利用した乗員の受動運動における運動量を増大させることができる。 On the other hand, as shown in FIG. 4 (B), when a sufficient amount of air is discharged from the seat front part airbags 12 and 13, the occupant direction of the seat front part airbags 12 and 13 ( The amount of protrusion in the (substantially Z-axis direction) is zero. Therefore, as shown in FIG. 4B, the seat surface of the seat cushion 10 is inclined forward (X-axis direction) as a whole. Thus, when the seat surface of the seat cushion 10 is tilted forward, the posture of the occupant seated on the seat cushion 10 is also tilted forward (in the X-axis direction). For example, inertia when the vehicle is accelerated or decelerated The force makes it easier for the occupant's body to move in the front-rear direction (X-axis direction), and the exercise load (muscle load) necessary for the occupant to maintain the posture can be increased. In particular, by tilting the posture of the occupant forward so that the occupant does not approach the seat back 20, it is possible to further increase the exercise load (muscle load) necessary for the occupant to maintain the posture. As described above, the seat device 100 according to the present embodiment uses the kinetic energy of the vehicle by discharging air from the seat front part airbags 12 and 13 and tilting the seat cushion 10 forward. The amount of exercise in the passive movement of the occupant can be increased.
　エアポンプ４０は、ホース４１～４５にそれぞれ接続しており、これらホース４１～４５を介して、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１、および一対の座面前方部エアバック１２，１３内に空気を送り込み、あるいは、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１、および一対の座面前方部エアバック１２，１３内から空気を排出することができる。なお、エアポンプ４０は、各エアバック２１，２２，１１，１２，１３内の空気量を調整するために専用のエアポンプであってもよいし、あるいは、車内空調装置と兼用のエアポンプであってもよい。 The air pump 40 is connected to the hoses 41 to 45, respectively, and through these hoses 41 to 45, the thoracic vertebra part airbag 21, the lumbar vertebra part airbag 22, the seat surface rear part airbag 11, and a pair of seat surface fronts are provided. Air is sent into the part airbags 12 and 13, or the thoracic part airbag 21, the lumbar part airbag 22, the seat rear part airbag 11, and the pair of seat front part airbags 12 and 13. Can be discharged. The air pump 40 may be a dedicated air pump for adjusting the amount of air in each of the air bags 21, 22, 11, 12, 13, or may be an air pump that is also used as an in-vehicle air conditioner. Good.
　また、図２に示すように、各ホース４１～４５には空気弁５１～５５がそれぞれ設けられており、後述する制御装置３００により、空気弁５１～５５の開閉を制御することで、各エアバック２１，２２，１１，１２，１３ごとに空気量の調整を行うことができる。 As shown in FIG. 2, air valves 51 to 55 are provided in the respective hoses 41 to 45, respectively. By controlling the opening and closing of the air valves 51 to 55 by a control device 300 described later, the air valves 51 to 55 are controlled. The amount of air can be adjusted for each of the backs 21, 22, 11, 12, and 13.
　図１に戻り、姿勢検出装置２００は、乗員の姿勢を検出するための装置であり、たとえば、シート装置１００の座面やシートベルトに設置された複数の圧力センサから構成することができる。たとえば、姿勢検出装置２００が複数の圧力センサから構成されている場合、姿勢検出装置２００は、シート装置１００やシートベルトに設置された複数の圧力センサで検出された圧力の分布から、乗員の姿勢を検出することができる。 Referring back to FIG. 1, the posture detection device 200 is a device for detecting the posture of the occupant, and can be composed of, for example, a plurality of pressure sensors installed on the seat surface of the seat device 100 or the seat belt. For example, when the posture detection device 200 includes a plurality of pressure sensors, the posture detection device 200 determines the occupant's posture from the distribution of pressures detected by the plurality of pressure sensors installed on the seat device 100 or the seat belt. Can be detected.
　また、姿勢検出装置２００は、複数の圧力センサに加えて、または複数の圧力センサに代えて、乗員を撮像するカメラを備える構成としてもよい。この場合、姿勢検出装置２００は、乗員を撮像した撮像画像に基づいて、乗員の身体の向き大きさなどを検出することで、乗員の姿勢をより適切に検出することができる。 Further, the posture detection device 200 may be configured to include a camera that captures an occupant in addition to or instead of the plurality of pressure sensors. In this case, the posture detection device 200 can detect the occupant's posture more appropriately by detecting the direction of the occupant's body based on the captured image obtained by capturing the occupant.
　制御装置３００は、シート装置１００を制御するためのプログラムが格納されたＲＯＭ（Read Only Memory）と、このＲＯＭに格納されたプログラムを実行するＣＰＵ（Central Processing Unit）と、アクセス可能な記憶装置として機能するＲＡＭ（Random Access Memory）とを備える。なお、動作回路としては、ＣＰＵ（Central Processing Unit）に代えて又はこれとともに、ＭＰＵ（Micro Processing Unit）、ＤＳＰ（Digital Signal Processor）、ＡＳＩＣ（Application Specific Integrated Circuit）、ＦＰＧＡ（Field Programmable Gate Array）などを用いることができる。 The control device 300 includes a ROM (Read Only Memory) that stores a program for controlling the seat device 100, a CPU (Central Processing Unit) that executes the program stored in the ROM, and an accessible storage device. It has a functioning RAM (Random Access Memory). As an operation circuit, instead of or in addition to a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc. Can be used.
　制御装置３００は、ＲＯＭに格納されたプログラムをＣＰＵにより実行することにより、乗員を認識する乗員認識機能と、各エアバックを制御して乗員の姿勢を変化させる運動制御機能と、運動制御機能により変化した乗員の姿勢に基づいて、各エアバックを制御するためのフィードバック補正量を算出する補正量算出機能とを実現する。以下に、制御装置３００が備える各機能について説明する。 The control device 300 executes a program stored in the ROM by the CPU, thereby occupant recognition function for recognizing the occupant, a motion control function for changing the posture of the occupant by controlling each airbag, and a motion control function. Based on the changed posture of the occupant, a correction amount calculation function for calculating a feedback correction amount for controlling each airbag is realized. Below, each function with which the control apparatus 300 is provided is demonstrated.
　乗員認識機能は、シート装置１００に着座した乗員を認識する。乗員認識機能による乗員の認識方法は、特に限定されないが、たとえば、図示しないカメラにより乗員の顔部を撮像し、撮像画像を予め記憶した乗員の顔画像と照合することで、乗員を認識することができる。 The occupant recognition function recognizes an occupant seated on the seat device 100. The method for recognizing the occupant by the occupant recognition function is not particularly limited. For example, the occupant is recognized by capturing the occupant's face with a camera (not shown) and comparing the captured image with the pre-stored occupant's face image. Can do.
　制御装置３００の運動制御機能は、たとえば、車両が高速道路を走行している場合など、運転者の運転負荷が低い場合には、運転者が着座するシート装置１００において、空気弁５１，５２，５３を開き、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１内に空気を供給するように、エアポンプ４０を動作させることで、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１の突出量を大きくする。これにより、運転者の運転負荷が低い場合には、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）が増加するように、乗員の姿勢を変化させることができる。同様に、運転者の運転負荷が低い場合には、運動制御機能は、空気弁５４，５５を開き、一対の座面前方部エアバック１２，１３内から空気を排出させるように、エアポンプ４０を動作させことで、シートクッション１０を前方に傾けて、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）が増加するように、乗員の姿勢を変化させることができる。 When the driving load on the driver is low, for example, when the vehicle is traveling on a highway, the motion control function of the control device 300 is used in the air valve 51, 52, 53, and the air pump 40 is operated so as to supply air into the thoracic vertebra part airbag 21, the lumbar vertebra part airbag 22, and the seat back part airbag 11, so that the thoracic vertebra part airbag 21 and lumbar part airbag 22, The protrusion amount of the seat surface rear portion airbag 11 is increased. Thus, when the driving load on the driver is low, the posture of the occupant can be changed so that the exercise load (muscle load) necessary for the occupant to maintain the posture increases. Similarly, when the driver's driving load is low, the motion control function opens the air valves 54 and 55 and causes the air pump 40 to discharge air from the pair of seat surface front airbags 12 and 13. By operating the seat cushion 10, the posture of the occupant can be changed so that the exercise load (muscle load) necessary for the occupant to maintain the posture is increased by tilting the seat cushion 10 forward.
　一方、運動制御機能は、たとえば、車両が細街路を走行している場合など、運転者の運転負荷が高い場合には、運転者が着座するシート装置１００において、空気弁５１，５２，５３を開き、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１内から空気を排出するように、エアポンプ４０を動作させることで、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１の突出量を小さくする。これにより、シートクッション１０全体、シートバック２０全体で乗員の身体をサポートし、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）が軽減するように、乗員の姿勢を変化させることができる。また同様に、運動制御機能は、運転者の運転負荷が高い場合には、空気弁５４，５５を開き、座面前方部エアバック１２，１３内に十分な空気を供給するように、エアポンプ４０を動作させることで、シートクッション１０の座面の傾きを略水平にし、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）を軽減するように、乗員の姿勢を変化させることができる。なお、運転制御機能は、図示しないナビゲーション装置から自車両１が走行している道路の情報を取得することで、自車両１が高速道路や細街路を走行しているか否かを判断することができる。 On the other hand, when the driver's driving load is high, for example, when the vehicle is traveling on a narrow street, the motion control function enables the air valves 51, 52, 53 in the seat device 100 on which the driver is seated. The thoracic vertebrae airbag 21, the lumbar vertebrae airbag 22, and the lumbar vertebrae airbag 22, The protrusion amount of the seat surface rear portion airbag 11 is reduced. Thus, the posture of the occupant can be changed so that the occupant's body is supported by the entire seat cushion 10 and the entire seat back 20 and the exercise load (muscle load) necessary for the occupant to maintain the posture is reduced. it can. Similarly, when the driving load on the driver is high, the motion control function opens the air valves 54 and 55 and supplies sufficient air into the seat front portion airbags 12 and 13. , The posture of the seat cushion 10 can be made substantially horizontal, and the posture of the occupant can be changed so as to reduce the exercise load (muscle load) necessary for the occupant to maintain the posture. . The driving control function can determine whether or not the host vehicle 1 is traveling on a highway or a narrow street by acquiring information on the road on which the host vehicle 1 is traveling from a navigation device (not shown). it can.
　また、本実施形態において、運動制御機能は、後述する補正量算出機能によりフィードバック補正量が算出された場合には、各エアバック２１，２２，１１，１２，１３を制御する際に、フィードバック補正量を加味して、各エアバック２１，２２，１１，１２，１３の駆動量を制御する（各エアバック２１，２２，１１，１２，１３の駆動量のフィードバック制御を行う。）。なお、運動制御機能によるフィードバック制御については、後述する。 In the present embodiment, the motion control function performs feedback correction when controlling the airbags 21, 22, 11, 12, and 13 when a feedback correction amount is calculated by a correction amount calculation function described later. The driving amount of each airbag 21, 22, 11, 12, 13 is controlled in consideration of the amount (feedback control of the driving amount of each airbag 21, 22, 11, 12, 13 is performed). Note that feedback control by the motion control function will be described later.
　制御装置３００の補正量算出機能は、運動制御機能により各エアバック２１，２２，１１，１２，１３を駆動させている際の乗員の姿勢に基づいて、各エアバック２１，２２，１１，１２，１３の駆動量を調整するためのフィードバック補正量を算出する。たとえば、運転者の受動運動による運動量を増加させるために、胸椎部エアバック２１、腰椎部エアバック２２、および座面後方部エアバック１１を乗員側に突出させた場面において、乗員の体型や着座姿勢などによっては、乗員の身体をエアバック２１，２２，１１で適切に押すことができず、たとえば乗員の姿勢が左右のいずれか一方を向いた状態となってしまう場合がある。このような場合、補正量算出機能は、姿勢検出装置２００により検出されたシート装置１００に加わる圧力の分布に基づく乗員の姿勢から、乗員が前を向いて、乗員の姿勢が受動運動を適切に行える姿勢となるように、各エアバック２１，２２，１１の突出量の補正量をフィードバック補正量として算出する。 The correction amount calculation function of the control device 300 is based on the posture of the occupant when the airbags 21, 22, 11, 12, and 13 are driven by the motion control function. , 13 is calculated as a feedback correction amount for adjusting the drive amount. For example, in the scene where the thoracic vertebra part airbag 21, the lumbar vertebra part airbag 22, and the seat rear part airbag 11 are projected toward the occupant in order to increase the amount of exercise by the driver's passive movement, the occupant's body shape and seating Depending on the posture and the like, the occupant's body cannot be properly pushed by the airbags 21, 22, and 11, and for example, the occupant's posture may be in a state of facing either the left or right. In such a case, the correction amount calculating function appropriately determines that the occupant faces forward and the occupant's posture appropriately performs passive motion from the occupant's posture based on the distribution of pressure applied to the seat device 100 detected by the posture detection device 200. The correction amount of the protrusion amount of each airbag 21, 22, 11 is calculated as a feedback correction amount so that the posture can be performed.
　そして、補正量算出機能により算出されたフィードバック補正量は、運動制御機能に出力され、運動制御機能は、フィードバック補正量を加味して、各エアバック２１，２２，１１，１２，１３を制御する。たとえば、胸椎部エアバック２１の突出量を大きくするフィードバック補正量が算出された場合、運動制御機能は、このフィードバック補正量に応じた分だけ胸椎部エアバック２１の突出量が大きくなるように、エアポンプ４０を介して、胸椎部エアバック２１内に空気を供給する。これにより、乗員の姿勢に応じて胸椎部エアバック２１の突出量が調整され、それぞれの乗員の体型や着座姿勢などが異なる場合でも、乗員に受動運動を適切に行わせることができる。なお、補正量算出機能は、算出したフィードバック補正量を、乗員認識機能により認識した乗員の情報に関連付けてデータベース４００に記憶する。これにより、次回、乗員がシート装置１００に着座した際に、乗員認識機能により乗員を認識することで、認識された乗員に対応するフィードバック補正量を加味して、直ぐに、各エアバック２１，２２，１１，１２，１３の駆動量を制御することができる。 The feedback correction amount calculated by the correction amount calculation function is output to the motion control function, and the motion control function controls the airbags 21, 22, 11, 12, and 13 with the feedback correction amount taken into account. . For example, when a feedback correction amount that increases the amount of protrusion of the thoracic vertebra airbag 21 is calculated, the motion control function increases the amount of protrusion of the thoracic portion airbag 21 by an amount corresponding to the feedback correction amount. Air is supplied into the thoracic vertebra airbag 21 through the air pump 40. Thereby, the protrusion amount of the thoracic vertebra part airbag 21 is adjusted according to the posture of the occupant, and even when the occupant's body shape, seating posture, and the like are different, the occupant can appropriately perform passive exercise. The correction amount calculation function stores the calculated feedback correction amount in the database 400 in association with the occupant information recognized by the occupant recognition function. As a result, when the occupant sits on the seat device 100 next time, the occupant recognition function recognizes the occupant, so that the feedback correction amount corresponding to the recognized occupant is taken into account and the airbags 21 and 22 are immediately added. , 11, 12, and 13 can be controlled.
　また、本実施形態では、図示しない入力部を介して、乗員が所望する受動運動の運動量を選択することができ、運動制御機能は、乗員により受動運動の運動量が選択された場合には、選択された運動量に応じた運動量が得られるように、胸椎部エアバック２１、腰椎部エアバック２２、および座面後方部エアバック１１の突出量や、座面前方部エアバック１２，１３内の空気量を制御する。 Further, in the present embodiment, it is possible to select the amount of passive motion desired by the occupant via an input unit (not shown), and the motion control function is selected when the amount of passive motion is selected by the occupant. The amount of protrusion of the thoracic vertebra part airbag 21, the lumbar vertebra part airbag 22, and the seat rear part airbag 11 and the air in the seat front part airbags 12 and 13 are obtained so as to obtain a momentum corresponding to the exercise quantity. Control the amount.
　さらに、本実施形態では、たとえば、胸椎部エアバック２１に接続する空気弁５１と、腰椎部エアバック２２に接続する空気弁５２と、座面後方部エアバック１１に接続する空気弁５３とを同時に開き、エアポンプ４０により各エアバック２１，２２，１１内から同時に空気を排出させることで、迅速に、乗員の姿勢をサポートすることができる。 Further, in the present embodiment, for example, an air valve 51 connected to the thoracic vertebra part airbag 21, an air valve 52 connected to the lumbar part airbag 22, and an air valve 53 connected to the seat surface rear part airbag 11. By simultaneously opening the air pump 40 and exhausting air from the air bags 21, 22 and 11 simultaneously, the posture of the occupant can be supported quickly.
　データベース４００は、制御装置３００により認識された乗員ごとに、制御装置３００により算出されたフィードバック補正量を記憶する。すなわち、データベース４００は、それぞれの乗員に応じたフィードバック補正量を、乗員ごとに記憶する。 The database 400 stores the feedback correction amount calculated by the control device 300 for each occupant recognized by the control device 300. That is, the database 400 stores a feedback correction amount corresponding to each occupant for each occupant.
　次に、本実施形態に係るシート装置１００の制御処理について説明する。図５は、第１実施形態の制御処理を示すフローチャートである。 Next, control processing of the sheet apparatus 100 according to the present embodiment will be described. FIG. 5 is a flowchart showing the control processing of the first embodiment.
　まず、ステップＳ１０１では、制御装置３００の乗員認識機能により乗員の認識が行われる。たとえば、乗員認識機能は、図示しないカメラにより乗員の顔部を撮像し、撮像画像を予め記憶した乗員の顔画像と照合することで、乗員を認識することができる。 First, in step S101, the occupant is recognized by the occupant recognition function of the control device 300. For example, the occupant recognition function can recognize an occupant by capturing an image of the occupant's face with a camera (not shown) and comparing the captured image with a previously stored occupant's face image.
　ステップＳ１０２では、制御装置３００の運動制御機能により、ステップＳ１０１で認識された乗員のフィードバック補正量をデータベース４００から抽出する処理が行われる。なお、ステップＳ１０１で乗員を認識することができなかった場合には、そのままステップＳ１０３に進むこととなる。 In step S102, the motion control function of the control device 300 performs processing for extracting the occupant feedback correction amount recognized in step S101 from the database 400. If the occupant cannot be recognized in step S101, the process proceeds to step S103 as it is.
　ステップＳ１０３では、運動制御機能により、各エアバック２１，２２，１１，１２，１３の制御が行われる。たとえば、運動制御機能は、自車両１が細街路を走行しており、運転者の運転負荷が高いと判断した場合には、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１の突出量を小さくし、あるいは、シートクッション１０の座面の傾きを略水平にすることで、運転者の受動運動による運動量が小さくなるように、運転者の姿勢を変化させる。また、運動制御機能は、各エアバック２１，２２，１１，１２，１３を制御する際に、ステップＳ１０２で抽出したフィードバック量を加味し、たとえばエアバック２１，２２，１１，１２，１３のうち、胸椎部エアバック２１の突出量のみを大きくするようなフィードバック補正量が抽出された場合、フィードバック補正量に応じた分だけ胸椎部エアバック２１の突出量が大きくなるように、胸椎部エアバック２１内に空気を供給する。これにより、乗員の体型や着座姿勢などに関わらず、それぞれの乗員に一定の受動運動の運動量を行わせることができる。 In step S103, the airbags 21, 22, 11, 12, and 13 are controlled by the motion control function. For example, when the host vehicle 1 is traveling on a narrow street and it is determined that the driver's driving load is high, the motion control function is such that the thoracic vertebra airbag 21, the lumbar airbag 22, and the seat rear portion airbag. By reducing the amount of protrusion of the back 11 or making the inclination of the seat surface of the seat cushion 10 substantially horizontal, the posture of the driver is changed so that the amount of momentum due to the passive movement of the driver is reduced. The motion control function takes into account the feedback amount extracted in step S102 when controlling the airbags 21, 22, 11, 12, and 13, for example, among the airbags 21, 22, 11, 12, and 13. When a feedback correction amount that only increases the protrusion amount of the thoracic vertebra airbag 21 is extracted, the thoracic airbag portion is increased so that the protrusion amount of the thoracic airbag 21 increases by an amount corresponding to the feedback correction amount. Air is supplied into 21. Thereby, it is possible to cause each occupant to perform a certain amount of passive exercise regardless of the occupant's body shape or sitting posture.
　ステップＳ１０４では、姿勢検出装置２００により、乗員の姿勢の検出が行われる。具体的には、姿勢検出装置２００は、ステップＳ１０３において運動制御機能により乗員の姿勢を変化させた際に乗員の身体がシート装置１００に加える圧力の分布を検出することで、運動制御機能により乗員の姿勢を変化させている際の乗員の姿勢を検出する。姿勢検出装置２００により検出された乗員の姿勢の情報は、制御装置３００に送信される。 In step S104, the posture detection device 200 detects the posture of the occupant. Specifically, the posture detection device 200 detects the distribution of the pressure applied by the occupant's body to the seat device 100 when the posture of the occupant is changed by the motion control function in step S103, so that the occupant uses the motion control function. The posture of the occupant when the posture of the vehicle is changed is detected. Information on the posture of the occupant detected by the posture detection device 200 is transmitted to the control device 300.
　ステップＳ１０５では、制御装置３００の補正量算出機能により、ステップＳ１０４で検出された乗員の姿勢に基づいて、各エアバック２１，２２，１１，１２，１３をフィードバック制御するためのフィードバック補正量の算出が行われる。たとえば、補正量算出機能は、ステップＳ１０４で検出された乗員の姿勢から、胸椎部エアバック２１を突出させているにも拘らず、胸椎部エアバック２１で乗員の身体を十分に押せていないと判断した場合には、胸椎部エアバック２１の突出量が大きくなるように、フィードバック補正量を算出する。そして、ステップＳ１０６では、補正量算出機能により、ステップＳ１０５で算出されたフィードバック補正量が、乗員ごとにデータベース４００に記憶される。これにより、データベース４００に記憶されたフィードバック補正量が次回処理のステップＳ１０２において抽出されることとなる。 In step S105, the correction amount calculation function of the control device 300 calculates the feedback correction amount for performing feedback control of each of the airbags 21, 22, 11, 12, and 13 based on the posture of the occupant detected in step S104. Is done. For example, the correction amount calculation function does not sufficiently push the occupant's body with the thoracic vertebra airbag 21 even though the thoracic vertebra airbag 21 protrudes from the occupant's posture detected at step S104. If it is determined, the feedback correction amount is calculated so that the protruding amount of the thoracic vertebra airbag 21 is increased. In step S106, the correction amount calculation function stores the feedback correction amount calculated in step S105 in the database 400 for each occupant. As a result, the feedback correction amount stored in the database 400 is extracted in step S102 of the next process.
　以上のように、本実施形態では、各エアバック２１，２２，１１，１２，１３を駆動させている際の乗員の姿勢を検出し、検出した乗員の姿勢に基づいて、各エアバック２１，２２，１１，１２，１３の駆動量（空気量）をフィードバック制御する。このように、本実施形態では、乗員に対する各エアバック２１，２２，１１，１２，１３の実際の駆動状況に基づいて、各エアバック２１，２２，１１，１２，１３内の駆動量を調整し、乗員の姿勢を受動運動に適した姿勢に変化させることができるため、乗員の受動運動の運動効率を向上させることができる。 As described above, in the present embodiment, the posture of the occupant when the airbags 21, 22, 11, 12, and 13 are driven is detected, and the airbags 21 and 22 are detected based on the detected occupant posture. Feedback control of the drive amounts (air amounts) of 22, 11, 12, and 13 is performed. Thus, in this embodiment, the drive amount in each airbag 21, 22, 11, 12, 13 is adjusted based on the actual drive situation of each airbag 21, 22, 11, 12, 13 with respect to a passenger | crew. In addition, since the occupant's posture can be changed to a posture suitable for the passive exercise, the exercise efficiency of the occupant's passive exercise can be improved.
　また、本実施形態では、フィードバック補正量を算出した際に、算出したフィードバック補正量を、乗員に関連付けてデータベース４００に記憶する。そして、乗員に対応するフィードバック補正量をデータベース４００から取得し、取得したフィードバック補正量に基づいて、各エアバック２１，２２，１１，１２，１３の駆動を制御することで、各エアバック２１，２２，１１，１２，１３の駆動を、乗員ごとに適切に制御することができる。また、シート装置１００に乗員が着座した際に、乗員を認識し、認識乗員に対応するフィードバック補正量をデータベース４００から取得することで、乗員がシート装置１００に着座して直ぐに、乗員に適した駆動量で各エアバック２１，２２，１１，１２，１３を制御することができる。 In this embodiment, when the feedback correction amount is calculated, the calculated feedback correction amount is stored in the database 400 in association with the occupant. Then, the feedback correction amount corresponding to the occupant is acquired from the database 400, and by controlling the driving of each airbag 21, 22, 11, 12, 13 based on the acquired feedback correction amount, each airbag 21, The driving of 22, 11, 12, 13 can be appropriately controlled for each occupant. Further, when the occupant is seated on the seat device 100, the occupant is recognized and the feedback correction amount corresponding to the recognized occupant is acquired from the database 400, so that the occupant is suitable for the occupant immediately after sitting on the seat device 100. The airbags 21, 22, 11, 12, and 13 can be controlled by the driving amount.
　さらに、本実施形態では、シート装置１００やシートベルトに設置された複数の圧力センサにより、乗員の身体がシート装置１００に加える圧力の分布を検出することで、シート装置１００に着座した乗員の姿勢を高い精度で検出することができる。また、圧力センサによる乗員の姿勢の検出に加えて、カメラで撮像した画像に基づいて乗員の姿勢を検出することもでき、この場合、シート装置１００に着座した乗員の身体の向きなどを検出することで、乗員の姿勢をより適切に検出することができる。 Further, in the present embodiment, the posture of the occupant seated on the seat device 100 is detected by detecting the distribution of the pressure applied to the seat device 100 by the occupant's body by a plurality of pressure sensors installed on the seat device 100 or the seat belt. Can be detected with high accuracy. In addition to the detection of the occupant's posture by the pressure sensor, the occupant's posture can also be detected based on the image captured by the camera. In this case, the orientation of the occupant's body seated on the seat device 100 is detected. Thus, the posture of the occupant can be detected more appropriately.

　≪第３実施形態≫
　次に、本発明の第３実施形態について説明する。図７は、第３実施形態に係るシート装置の制御システムを備えた車両１ａの構成を示すブロック図である。図７に示すように、車両１ａは、シート装置１００と、生体信号検出装置５００と、制御装置３００とを備える。なお、シート装置１００は、第１実施形態に係るシート装置１００と同様の構成のため説明は省略する。 «Third embodiment»
Next, a third embodiment of the present invention will be described. FIG. 7 is a block diagram illustrating a configuration of a vehicle 1a including the seat device control system according to the third embodiment. As shown in FIG. 7, the vehicle 1 a includes a seat device 100, a biological signal detection device 500, and a control device 300. Note that the sheet apparatus 100 has the same configuration as that of the sheet apparatus 100 according to the first embodiment, and a description thereof will be omitted.
　生体信号検出装置５００は、乗員の身体状態を推定するために、乗員の生体信号を検出する。このような生体信号検出装置５００としては、シート装置１００に搭載され、乗員の身体がシート装置１００に加える圧力を検出する圧力センサ、シートベルトやシート装置１００の座面に設置され、乗員の心拍を検出する心拍センサ、乗員の血圧を検出する血圧センサ、乗員の基礎代謝（呼気）を検出する基礎代謝センサ（ＣＯ２センサ）、乗員の体温を検出する赤外線センサ、および、乗員の目の瞬き、表情、頭部の動きなどを撮像するカメラなどが挙げられる。生体信号検出装置５００により検出された乗員の生体信号は制御装置３００に送信される。 The biological signal detection device 500 detects an occupant's biological signal in order to estimate the occupant's physical state. Such a biological signal detection device 500 is mounted on the seat device 100, installed on the seat surface of the seat belt or the seat surface of the seat device 100, a pressure sensor that detects the pressure applied to the seat device 100 by the occupant's body, and the heart rate of the occupant A heart rate sensor that detects occupant blood pressure, a blood pressure sensor that detects occupant blood pressure, a basal metabolism sensor (CO 2 sensor) that detects occupant metabolism (exhalation), an infrared sensor that detects the body temperature of the occupant, and a blink of the occupant's eyes And a camera that images facial expressions, head movements, and the like. The occupant's biological signal detected by the biological signal detection device 500 is transmitted to the control device 300.
　第３実施形態に係る制御装置３００は、第１実施形態の制御装置３００の補正量算出機能に代えて、乗員の生体信号を取得する生体信号取得機能と、取得した乗員の生体信号に基づいて、乗員の身体状態を推定する身体状態推定機能とを有する。 The control device 300 according to the third embodiment replaces the correction amount calculation function of the control device 300 according to the first embodiment with a biological signal acquisition function that acquires an occupant's biological signal and the acquired occupant's biological signal. And a body state estimating function for estimating the body state of the occupant.
　制御装置３００の生体信号取得機能は、生体信号検出装置５００により検出された乗員の生体信号を取得する。第３実施形態では、たとえば、乗員の身体によりシート装置１００に加えられた圧力、乗員の心拍、血圧、基礎代謝（呼気）、体温、および、目の瞬き、表情、頭部の動きなどの情報が生体信号として取得される。 The biological signal acquisition function of the control device 300 acquires an occupant's biological signal detected by the biological signal detection device 500. In the third embodiment, for example, information such as pressure applied to the seat device 100 by the occupant's body, occupant's heartbeat, blood pressure, basal metabolism (exhalation), body temperature, blink of eyes, facial expression, head movement, etc. Is obtained as a biological signal.
　制御装置３００の身体状態推定機能は、生体信号取得機能により取得された乗員の生体信号に基づいて、乗員の身体状態を推定する。たとえば、身体状態推定機能は、生体信号検出装置５００により撮像された乗員の撮像画像に基づいて、乗員の頭部が揺れている、乗員の目の瞬きが多い、閉眼時間が長い、あくびが多いなどと判断した場合には、乗員は疲労状態にあり、受動運動に適さない状態であると推定することができる。さらに、身体状態推定機能は、たとえば乗員の心拍が低下して、乗員の心拍数が所定値以下となった場合、または、乗員の体温が低下して、乗員の体温が所定温度以下となった場合には、乗員は疲労状態であり、受動運動に適さない状態であると推定することができる。さらに、身体状態推定機能は、たとえば、乗員の体温が所定値以上である場合には、乗員は風邪などによる発熱状態であり、受動運動に適さない状態であると推定することができる。このように、身体状態推定機能は、乗員の生体信号に基づいて、乗員が、受動運動に適した状態であるか、あるいは、受動運動に適さない状態であるかを推定する。 The body state estimation function of the control device 300 estimates the occupant's body state based on the occupant's biological signal acquired by the biological signal acquisition function. For example, the body state estimation function is based on the occupant's captured image captured by the biological signal detection device 500, the occupant's head is shaking, the occupant's eyes are blinking frequently, the eye is closed for a long time, and there is a lot of yawning. It can be estimated that the passenger is in a fatigued state and is not suitable for passive exercise. Furthermore, the body state estimation function is, for example, when the occupant's heart rate is reduced and the occupant's heart rate is equal to or lower than a predetermined value, or the occupant's body temperature is decreased and the occupant's body temperature is lower than or equal to the predetermined temperature. In some cases, it can be assumed that the occupant is in a fatigued state and not suitable for passive exercise. Furthermore, for example, when the body temperature of the occupant is equal to or higher than a predetermined value, the body state estimation function can estimate that the occupant is in a heat generation state due to a cold or the like and is not suitable for passive exercise. Thus, the body state estimation function estimates whether the occupant is in a state suitable for passive exercise or in a state unsuitable for passive exercise based on the occupant's biological signal.
　また、第３実施形態において、制御装置３００の運動制御機能は、身体状態推定機能により推定された乗員の身体状態に基づいて、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１、および、座面前方部エアバック１２，１３の制御を行う。たとえば、運動制御機能は、身体状態推定機能による推定の結果、乗員が受動運動に適した状態から受動運動に適さない状態へと変化した場合に、空気弁５１，５２，５３を開き、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１内から空気を排出するようにエアポンプ４０を動作させることで、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１の突出量を小さくする。これにより、乗員が受動運動に適さない状態である場合には、シートクッション１０全体、シートバック２０全体で乗員の身体をサポートし、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）が軽減するように、乗員の姿勢を変化させることができる。また同様に、運動制御機能は、乗員が受動運動に適さない状態である場合には、座面前方部エアバック１２，１３内に十分な空気を供給して、シートクッション１０の座面の傾きを略水平にすることで、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）を軽減するように、乗員の姿勢を変化させる。 In the third embodiment, the motion control function of the control device 300 is based on the occupant's physical condition estimated by the physical condition estimation function, and the thoracic vertebra part airbag 21, the lumbar vertebra part airbag 22, and the seat rear part airbag. The back 11 and the seat front part airbags 12 and 13 are controlled. For example, the motion control function opens the air valves 51, 52, and 53 when the occupant changes from a state suitable for passive motion to a state unsuitable for passive motion as a result of estimation by the body state estimation function. By operating the air pump 40 so as to discharge air from the airbag 21, the lumbar portion airbag 22, and the seat back portion airbag 11, the thoracic vertebra portion airbag 21, the lumbar portion airbag 22, and the seat back portion air The amount of protrusion of the back 11 is reduced. Thus, when the occupant is not suitable for passive exercise, the entire seat cushion 10 and the entire seat back 20 support the occupant's body and exercise load (muscle load) necessary for the occupant to maintain the posture. The occupant's posture can be changed so as to alleviate. Similarly, when the occupant is not suitable for passive motion, the motion control function supplies sufficient air into the seat front portion airbags 12 and 13 to incline the seat cushion 10 seat surface. By substantially leveling the vehicle, the posture of the occupant is changed so as to reduce the exercise load (muscle load) necessary for the occupant to maintain the posture.
　一方、たとえば、身体状態推定機能による推定の結果、乗員が受動運動に適さない状態から受動運動に適した状態に変化した場合に、運動制御機能は、空気弁５１，５２，５３を開いて、胸椎部エアバック２１、腰椎部エアバック２２、あるいは、座面後方部エアバック１１内に空気を送り込むように、エアポンプ４０を動作させる。これにより、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１を乗員側に突出させることができ、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）が増加するように、乗員の姿勢を変化させることができる。同様に、乗員が受動運動に適した状態である場合、運動制御機能は、一対の座面前方部エアバック１２，１３内から空気を排出させて、シートクッション１０を前方に傾けることで、乗員が姿勢を維持するために必要な運動負荷（筋肉負荷）が増加するように、乗員の姿勢を変化させることができる。 On the other hand, for example, when the occupant changes from a state not suitable for passive motion to a state suitable for passive motion as a result of estimation by the body state estimation function, the motion control function opens the air valves 51, 52, 53, The air pump 40 is operated so as to send air into the thoracic vertebra part airbag 21, the lumbar part airbag 22, or the seat surface rear part airbag 11. Thereby, the thoracic vertebra part airbag 21, the lumbar vertebra part airbag 22, and the seat back part airbag 11 can be protruded to the occupant side, and the exercise load (muscle load) necessary for the occupant to maintain the posture increases. As a result, the posture of the occupant can be changed. Similarly, when the occupant is in a state suitable for passive motion, the motion control function allows the occupant to exhaust air from inside the pair of seat surface front portion airbags 12 and 13 and tilt the seat cushion 10 forward. The posture of the occupant can be changed so that the exercise load (muscle load) necessary for maintaining the posture increases.
　このように、第３実施形態において、運動制御機能は、乗員の身体状態が受動運動に適さない状態である場合には、乗員の運動負荷が軽減するように乗員の姿勢を変化させ、一方、乗員の身体状態が受動運動に適した状態である場合には、乗員の運動負荷が増加するように乗員の姿勢を変化させる。また、上述の例では、乗員の身体状態を、受動運動に適した状態であるか、受動運動に適さない状態であるかの２段階で推定する構成を例示したが、この構成に限定されず、３段階以上の状態で推定する構成とすることができる。この場合、運動制御機能は、乗員の身体状態が受動運動に適した状態であるほど、乗員の運動負荷が増加されるように乗員の姿勢を変化させ、乗員の身体状態が受動運動に適さない状態であるほど、乗員の運動負荷が軽減されるように乗員の姿勢を変化させることができる。 Thus, in the third embodiment, the motion control function changes the posture of the occupant so as to reduce the occupant's exercise load when the occupant's physical state is not suitable for passive exercise, When the occupant's physical condition is suitable for passive exercise, the occupant's posture is changed so that the occupant's exercise load increases. Further, in the above-described example, the configuration in which the occupant's physical state is estimated in two stages, which is a state suitable for passive exercise or a state not suitable for passive exercise, is illustrated, but the present invention is not limited to this configuration. It can be set as the structure estimated in the state of three steps or more. In this case, the motion control function changes the posture of the occupant so that the exercise load of the occupant is increased as the occupant's physical state is more suitable for passive exercise, and the occupant's physical state is not suitable for passive exercise. The occupant's posture can be changed so that the exercise load on the occupant is reduced as the state is increased.
　次に、第３実施形態に係るシート装置１００の制御処理について説明する。図８は、第３実施形態の制御処理を示すフローチャートである。 Next, control processing of the sheet apparatus 100 according to the third embodiment will be described. FIG. 8 is a flowchart showing the control process of the third embodiment.
　まず、ステップＳ２０１では、生体信号検出装置５００により乗員の生体信号の検出が行われる。たとえば、生体信号検出装置５００は、乗員の身体がシート装置１００に加える圧力、乗員の心拍、基礎代謝（呼気）、体温、および、乗員の目の瞬き、表情、頭部の動きなどを乗員の生体信号として検出する。そして、生体信号検出装置５００により検出された乗員の生体信号は、制御装置３００に送信され、制御装置３００の生体信号取得機能により取得されることとなる。 First, in step S201, the biological signal detection device 500 detects the biological signal of the occupant. For example, the biological signal detection device 500 determines the pressure applied by the occupant's body to the seat device 100, the occupant's heartbeat, basal metabolism (exhalation), body temperature, and the occupant's eye blink, facial expression, head movement, etc. Detect as a biological signal. Then, the occupant's biological signal detected by the biological signal detection device 500 is transmitted to the control device 300 and acquired by the biological signal acquisition function of the control device 300.
　ステップＳ２０２では、制御装置３００の身体状態推定機能により、ステップＳ２０１で検出された乗員の生体信号に基づいて、乗員の身体状態の推定が行われる。たとえば、身体状態推定機能は、生体信号検出装置５００により撮像された撮像画像に基づいて、乗員の頭部が揺れている、瞬きが多いまたは閉眼時間が長い、あくびが多いなどを検出した場合に、乗員は疲労状態にあり、受動運動に適さない状態であると推定する。 In step S202, the occupant's body state is estimated based on the occupant's biological signal detected in step S201 by the body state estimation function of the control device 300. For example, the body state estimation function detects, based on a captured image captured by the biological signal detection device 500, that the occupant's head is shaking, blinking or having a long eye closure time, or yawning. It is estimated that the occupant is in a fatigued state and is not suitable for passive exercise.
　そして、ステップＳ２０３では、制御装置３００の運動制御機能により、ステップＳ２０２における推定の結果、乗員が受動運動に適さない状態であるか否かの判定が行われる。乗員が受動運動に適さない状態であると判定された場合には、ステップＳ２０４に進み、一方、乗員が受動運動に適した状態であると判定された場合には、ステップＳ２０５に進む。 In step S203, the motion control function of the control device 300 determines whether the occupant is not suitable for passive motion as a result of the estimation in step S202. If it is determined that the occupant is not suitable for passive exercise, the process proceeds to step S204. On the other hand, if it is determined that the occupant is suitable for passive exercise, the process proceeds to step S205.
　ステップＳ２０４では、乗員が受動運動に適さないであると判定されているため、運動制御機能により、乗員の運動負荷を軽減するために、乗員の受動運動における運動量が小さくなるように、各エアバック２１，２２，１１，１２，１３の制御が行われる。たとえば、運動制御機能は、乗員が受動運動に適さない状態である場合、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１内から空気を排出させて、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１の突出量を小さくし、あるいは、一対の座面前方部エアバック１２，１３内に空気を供給して、シートクッション１０の座面の傾きを略水平にすることで、乗員の受動運動による運動量が小さくなるように、乗員の姿勢を変化させる。これにより、乗員が受動運動に適さない状態である場合に、乗員に係る負荷を軽減することができる。なお、乗員の受動運動による運動量が十分に小さい場合には、このまま処理を終了してもよい。 In step S204, since it is determined that the occupant is not suitable for passive exercise, each air bag is reduced so that the amount of exercise in the passive exercise of the occupant is reduced by the exercise control function in order to reduce the exercise load of the occupant. Controls 21, 22, 11, 12, and 13 are performed. For example, when the occupant is in a state that is not suitable for passive motion, the motion control function causes the thoracic vertebra airbag to exhaust air from the thoracic vertebra airbag 21, the lumbar airbag 22, and the seat back airbag 11. 21. The protruding amount of the lumbar portion airbag 22 and the seat surface rear portion airbag 11 is reduced, or air is supplied into the pair of seat surface front portion airbags 12 and 13, so that the seat cushion 10 of the seat cushion 10 By making the inclination substantially horizontal, the posture of the occupant is changed so that the momentum due to the passive motion of the occupant is reduced. Thereby, when a passenger | crew is a state which is not suitable for a passive exercise, the load concerning a passenger | crew can be reduced. In addition, when the momentum by a passenger | crew's passive exercise | movement is small enough, you may complete | finish a process as it is.
　一方、ステップＳ２０５では、乗員が受動運動に適した状態であると判定されているため、運動制御機能により、乗員の受動運動における運動量が大きくなるように、各エアバック２１，２２，１１，１２，１３の制御が行われる。たとえば、運動制御機能は、乗員が受動運動に適した状態である場合、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１内に空気を供給して、胸椎部エアバック２１、腰椎部エアバック２２、座面後方部エアバック１１の突出量を大きくし、あるいは、一対の座面前方部エアバック１２，１３内から空気を排出させて、シートクッション１０の座面を傾けることで、乗員の受動運動による運動量が大きくなるように、乗員の姿勢を変化させる。これにより、乗員が受動運動に適した状態である場合には、乗員に係る運動負荷を増加することができる。なお、乗員の受動運動による運動量が十分に大きい場合には、このまま処理を終了してもよい。 On the other hand, in step S205, since it is determined that the occupant is in a state suitable for passive exercise, the airbags 21, 22, 11, 12 are controlled so that the amount of exercise in the passive exercise of the occupant is increased by the exercise control function. , 13 is controlled. For example, when the occupant is in a state suitable for passive motion, the motion control function supplies air into the thoracic vertebra airbag 21, the lumbar vertebra airbag 22, and the seat back posterior airbag 11, and the thoracic vertebra airbag. 21. Increase the protruding amount of the lumbar portion airbag 22 and the seat back portion airbag 11 or exhaust air from the pair of seat front portion airbags 12 and 13 so that the seat cushion 10 has a seat surface. By tilting, the posture of the occupant is changed so that the momentum of the occupant is increased. Thereby, when a passenger | crew is a state suitable for a passive exercise, the exercise | movement load concerning a passenger | crew can be increased. In addition, when the momentum by a passenger's passive exercise | movement is large enough, you may complete | finish a process as it is.
　なお、運動制御機能は、乗員が所定の受動運動の運動量を得られるように、各エアバック２１，２２，１１，１２，１３の一連の制御を、受動運動プログラムに従って行う構成としてもよい。この場合、たとえば、それぞれの大きさの運動量に応じた受動運動プログラムが制御装置３００のメモリに記憶されており、乗員が受動運動に適した状態であるほど、受動運動の運動量が大きい受動運動プログラムを実行し、乗員が受動運動に適さない状態であるほど、受動運動の運動量が小さい受動運動プログラムを実行する構成とすることができる。 The motion control function may be configured to perform a series of controls of the airbags 21, 22, 11, 12, and 13 in accordance with a passive motion program so that the occupant can obtain a predetermined amount of passive motion. In this case, for example, a passive exercise program corresponding to each amount of exercise is stored in the memory of the control device 300, and the passive exercise program has a larger amount of passive exercise as the passenger is more suitable for passive exercise. The passive motion program can be configured such that the more the passenger is not suitable for passive motion, the smaller the amount of passive motion is.
　以上のように、第３実施形態では、乗員の生体信号を検出し、検出された生体信号に基づいて、乗員の身体状態を推定する。そして、乗員が受動運動に適さない状態であると推定された場合には、乗員の受動運動の運動量が小さくなるように、各エアバック２１，２２，１１，１２，１３を制御することで、乗員の受動運動による運動量（運動負荷）を小さくする。一方、乗員が受動運動に適した状態であると推定された場合には、乗員の受動運動の運動量が大きくなるように、各エアバック２１，２２，１１，１２，１３を制御することで、乗員の受動運動による運動量（運動負荷）を大きくする。このように、第３実施形態では、それぞれの乗員の身体状態に応じて、それぞれの乗員の受動運動による運動量（運動負荷）を調整することができるため、乗員に、乗員の身体状態に応じた適切な運動量の受動運動を行わせることができる。 As described above, in the third embodiment, the occupant's biological signal is detected, and the occupant's body state is estimated based on the detected biological signal. And when it is estimated that the occupant is not suitable for passive exercise, by controlling the airbags 21, 22, 11, 12, and 13 so that the momentum of the passive exercise of the occupant becomes small, Reduce the amount of exercise (exercise load) caused by the passive movement of passengers. On the other hand, when it is estimated that the occupant is in a state suitable for passive motion, by controlling the airbags 21, 22, 11, 12, and 13 so that the momentum of the passive motion of the occupant increases, Increase the amount of exercise (exercise load) by the passive movement of the passengers. Thus, in 3rd Embodiment, since the amount of exercises (exercise load) by each occupant's passive exercise | movement can be adjusted according to each occupant's physical condition, according to the occupant's physical condition Passive exercise with appropriate momentum can be performed.
　≪第４実施形態≫
　続いて、本発明の第４実施形態について説明する。図９は、第４実施形態に係るシート装置１００の制御システムを備えた車両１ｂの構成を示すブロック図である。第４実施形態に係る車両１ｂは、以下に説明する点以外は、第３実施形態と同様の構成を有し、また、以下に説明するように動作すること以外は、第３実施形態と同様に動作する。 << Fourth Embodiment >>
Subsequently, a fourth embodiment of the present invention will be described. FIG. 9 is a block diagram illustrating a configuration of a vehicle 1b including a control system for the seat device 100 according to the fourth embodiment. The vehicle 1b according to the fourth embodiment has the same configuration as that of the third embodiment except for the points described below, and is the same as that of the third embodiment except that the vehicle 1b operates as described below. To work.
　第４実施形態において、車両１ｂは、第３実施形態の生体信号検出装置５００に代えて、車両コントローラ６００を備えている。車両コントローラ６００は、各種車載装置と接続しており、これら車載装置から車両の運転状態を示す情報を運転情報として取得する。このような運転情報としては、たとえば、車速、ステアリングの操舵角、アクセル開度、ブレーキ信号などの車両情報が含まれる。そして、車両コントローラ６００により検出された運転情報は、制御装置３００に送信される。 In the fourth embodiment, the vehicle 1b includes a vehicle controller 600 instead of the biological signal detection device 500 of the third embodiment. The vehicle controller 600 is connected to various in-vehicle devices, and acquires information indicating the driving state of the vehicle as driving information from these in-vehicle devices. Such driving information includes, for example, vehicle information such as vehicle speed, steering angle, accelerator opening, and brake signal. Then, the driving information detected by the vehicle controller 600 is transmitted to the control device 300.
　第４実施形態に係る制御装置３００は、第３実施形態の制御装置３００の生体信号取得機能に代えて、運転情報取得機能を備える。運転情報取得機能は、車両コントローラ６００から、車速、ステアリングの操舵角、アクセル開度、ブレーキ信号などの車両情報を、運転者による車両の運転状態を示す運転情報として取得する。 The control device 300 according to the fourth embodiment includes a driving information acquisition function instead of the biological signal acquisition function of the control device 300 of the third embodiment. The driving information acquisition function acquires vehicle information such as vehicle speed, steering angle, accelerator opening, and brake signal from the vehicle controller 600 as driving information indicating the driving state of the vehicle by the driver.
　また、第４実施形態において、制御装置３００の身体状態推定機能は、運転情報取得機能により取得された運転情報に基づいて、運転者の身体状態を推定する。たとえば、身体状態推定機能は、ステアリングの操舵角のバラツキから、自車両１ｂが蛇行していると判断した場合には、運転者は疲労状態にあり、受動運動に適さない状態であると推定することができる。また、身体状態推定機能は、たとえば、車速、ブレーキ開度、アクセル信号などのバラツキ度合が大きい場合には、運転者がストレス状態にあり、受動運動に適さない状態であると推定することができる。このように、第４実施形態において、身体状態推定機能は、運転情報に基づいて、運転者が疲労状態やストレス状態などの受動運動に適さない状態であるか、それとも、受動運動に適した状態であるかを推定する。 In the fourth embodiment, the body state estimation function of the control device 300 estimates the driver's body state based on the driving information acquired by the driving information acquisition function. For example, the body state estimation function estimates that the driver is in a fatigued state and is not suitable for passive motion when it is determined from the variation in the steering angle of the steering that the host vehicle 1b is meandering. be able to. In addition, the body state estimation function can estimate that the driver is in a stress state and is not suitable for passive exercise when the degree of variation in vehicle speed, brake opening, accelerator signal, etc. is large, for example. . As described above, in the fourth embodiment, the body state estimation function is based on the driving information so that the driver is in a state not suitable for passive exercise such as a fatigue state or a stress state, or a state suitable for passive exercise. It is estimated whether it is.
　次に、第４実施形態に係るシート装置１００の制御処理について説明する。図１０は、第４実施形態に係るシート装置１００の制御処理を示すフローチャートである。なお、以下においては、運転者が着座するシート装置１００の制御処理について説明する。 Next, control processing of the sheet apparatus 100 according to the fourth embodiment will be described. FIG. 10 is a flowchart showing a control process of the sheet apparatus 100 according to the fourth embodiment. In the following, the control process of the seat device 100 on which the driver is seated will be described.
　まず、ステップＳ３０１では、車両コントローラ６００により、運転者による車両の運転状態を示す運転情報の検出が行われる。たとえば、車両コントローラ６００は、各種車載装置から、車速、ステアリングの操舵角、アクセル開度、ブレーキ信号などの車両情報を運転情報として検出する。そして、車両コントローラ６００により検出された運転情報は、制御装置３００に送信され、制御装置３００の運転情報取得機能により取得される。 First, in step S301, the vehicle controller 600 detects driving information indicating the driving state of the vehicle by the driver. For example, the vehicle controller 600 detects vehicle information such as vehicle speed, steering angle, accelerator opening, and brake signal as driving information from various in-vehicle devices. Then, the driving information detected by the vehicle controller 600 is transmitted to the control device 300 and acquired by the driving information acquisition function of the control device 300.
　ステップＳ３０２では、身体状態推定機能により、ステップＳ３０１で検出された運転情報に基づいて、運転者の身体状態の推定が行われる。たとえば、身体状態推定機能は、車速、ブレーキ開度、アクセル信号などのバラツキ度合が高い場合には、運転者がストレス状態であり、受動運動に適さない状態であると推定する。 In step S302, the body state of the driver is estimated based on the driving information detected in step S301 by the body state estimating function. For example, the body state estimation function estimates that the driver is in a stress state and not suitable for passive exercise when the degree of variation in vehicle speed, brake opening, accelerator signal, etc. is high.
　そして、ステップＳ３０３～Ｓ３０５は、第３実施形態のステップＳ２０３～Ｓ２０５と同様の処理が行われる。すなわち、ステップＳ３０２における推定の結果、運転者が受動運動に適さない状態であると推定された場合（ステップＳ３０３＝Ｙｅｓ）には、運転者が着座するシート装置１００において、受動運動による運動量が小さくなるように、各エアバック２１，２２，１１，１２，１３の制御が行われ（ステップＳ３０４）、運転者が受動運動に適した状態であると推定された場合（ステップＳ３０３＝Ｎｏ）には、運転者が着座するシート装置１００において、受動運動による運動量が大きくなるように、各エアバック２１，２２，１１，１２，１３の制御が行われる（ステップＳ３０５）。 In steps S303 to S305, processing similar to that in steps S203 to S205 of the third embodiment is performed. That is, as a result of the estimation in step S302, when it is estimated that the driver is not suitable for passive exercise (step S303 = Yes), the amount of exercise due to passive exercise is small in the seat device 100 on which the driver is seated. Thus, the control of each airbag 21, 22, 11, 12, 13 is performed (step S304), and when it is estimated that the driver is in a state suitable for passive exercise (step S303 = No). Then, in the seat device 100 on which the driver is seated, the airbags 21, 22, 11, 12, and 13 are controlled so that the momentum by the passive movement is increased (step S305).
　以上のように、第４実施形態では、運転者による車両の運転状態を示す運転情報を検出し、検出した運転情報に基づいて、運転者の身体状態を推定する。これにより、第４実施形態では、第３実施形態の効果に加えて、一般に取得が容易な車速や操舵角などの車両情報からなる運転情報に基づいて、運転者の身体状態を推定することができるため、運転者の生体信号を検出する生体信号検出装置５００を省略することができ、シート装置１００の制御システムの省スペース化、低コスト化を図ることができる。 As described above, in the fourth embodiment, driving information indicating the driving state of the vehicle by the driver is detected, and the physical state of the driver is estimated based on the detected driving information. As a result, in the fourth embodiment, in addition to the effects of the third embodiment, the physical state of the driver can be estimated based on driving information including vehicle information such as vehicle speed and steering angle that are generally easy to acquire. Therefore, the biological signal detection device 500 that detects the driver's biological signal can be omitted, and the control system of the seat device 100 can be saved in space and cost can be reduced.
　≪第５実施形態≫
　続いて、本発明の第５実施形態について説明する。図１１は、第５実施形態に係るシート装置１００の制御システムを備えた車両１ｃの構成を示すブロック図である。第５実施形態に係る車両１ｃは、以下に説明する点以外は、第３実施形態と同様の構成を有し、また、以下に説明するように動作すること以外は、第３実施形態と同様に動作する。 «Fifth embodiment»
Subsequently, a fifth embodiment of the present invention will be described. FIG. 11 is a block diagram illustrating a configuration of a vehicle 1c including the control system for the seat device 100 according to the fifth embodiment. The vehicle 1c according to the fifth embodiment has the same configuration as that of the third embodiment except for the points described below, and is the same as that of the third embodiment except that the vehicle 1c operates as described below. To work.
　第５実施形態において、データベース４００は、乗員の身体情報の履歴情報を記憶している。具体的には、データベース４００は、制御装置３００により推定された乗員の身体情報の履歴情報を、乗員ごとに記憶している。 In the fifth embodiment, the database 400 stores history information of occupant body information. Specifically, the database 400 stores the history information of the occupant's body information estimated by the control device 300 for each occupant.
　第５実施形態において、制御装置３００の身体状態推定機能は、データベース４００に記憶された履歴情報を加味して、乗員の身体状態を推定する。具体的には、身体状態推定機能は、第３実施形態と同様に、生体信号検出装置５００により検出された乗員の生体信号に基づいて、乗員の身体状態を推定するとともに、乗員の生体信号に基づいて乗員の身体状態を推定する際に、乗員の履歴情報を加味して、乗員の身体状態の推定を行う。たとえば、身体状態推定機能は、乗員の履歴情報に基づいて、乗員の体調が低下する傾向にある時期を判断し、乗員の体調が低下する時期においては、乗員の身体状態を推定する際に、乗員は受動運動に適さない状態であると推定され易くすることができる。また、身体状態推定機能は、たとえば、直近の履歴情報に基づいて、乗員の最近の身体状態が受動運動に適さない状態であると判断した場合には、乗員の身体状態を推定する際に、乗員が受動運動に適さない状態であると推定され易くすることもできる。 In the fifth embodiment, the body state estimation function of the control device 300 estimates the occupant's body state in consideration of the history information stored in the database 400. Specifically, the body state estimation function estimates the occupant's physical state based on the occupant's biological signal detected by the biological signal detection device 500, and, similarly to the third embodiment, When estimating the occupant's physical condition based on the occupant's history information, the occupant's physical condition is estimated in consideration of the occupant's history information. For example, the body condition estimation function determines when the occupant's physical condition tends to decrease based on the occupant's history information, and when the occupant's physical condition decreases, when estimating the occupant's physical condition, The passenger can be easily estimated to be in a state not suitable for passive movement. In addition, when the body state estimation function determines that the latest body state of the occupant is not suitable for passive exercise based on the latest history information, for example, when estimating the body state of the occupant, It can also be easily estimated that the occupant is not suitable for passive motion.
　次に、第５実施形態に係るシート装置１００の制御処理について説明する。図１２は、第５実施形態に係るシート装置１００の制御処理を示すフローチャートである。 Next, control processing of the sheet apparatus 100 according to the fifth embodiment will be described. FIG. 12 is a flowchart showing a control process of the sheet apparatus 100 according to the fifth embodiment.
　まず、ステップＳ４０１では、第３実施形態のステップＳ２０１と同様に、生体信号検出装置５００により、乗員の身体状態の検出が行われる。 First, in step S401, the occupant's body condition is detected by the biological signal detection device 500, as in step S201 of the third embodiment.
　ステップＳ４０２では、制御装置３００の身体状態推定機能により、データベース４００に記憶された乗員の履歴情報の取得が行われる。具体的には、身体状態推定機能は、データベース４００に記憶された複数の乗員の履歴情報のうち、シート装置１００に着座した乗員の履歴情報を、データベース４００から取得する。なお、身体状態推定機能は、たとえば、図示しないカメラにより乗員の顔部を撮像し、撮像画像を予め記憶した乗員の顔画像と照合することで、シート装置１００に着座した乗員を認識することができる。 In step S402, the occupant history information stored in the database 400 is acquired by the body state estimation function of the control device 300. Specifically, the body state estimation function acquires, from the database 400, history information of the occupant seated on the seat device 100 among the history information of a plurality of occupants stored in the database 400. The body state estimation function recognizes an occupant seated on the seat device 100 by, for example, capturing the occupant's face with a camera (not shown) and comparing the captured image with the occupant's face image stored in advance. it can.
　ステップＳ４０３では、制御装置３００の身体状態推定機能により、ステップＳ４０１で検出された乗員の生体信号およびステップＳ４０２で取得された乗員の履歴情報に基づいて、乗員の身体状態の推定が行われる。たとえば、身体状態推定機能は、乗員の履歴情報から、乗員の体調が低下する傾向にある時期であると判断した場合や、乗員の最近の身体状態が受動運動に適さない状態であると判断した場合には、乗員の生体信号に基づいて乗員の身体状態を推定する際に、乗員が受動運動に適さない状態であると推定され易くすることができる。 In step S403, the body state of the occupant is estimated based on the occupant's biological signal detected in step S401 and the occupant history information acquired in step S402 by the body state estimation function of the control device 300. For example, the body condition estimation function determines that it is a time when the physical condition of the occupant tends to decrease from the occupant's history information, or that the occupant's recent physical condition is not suitable for passive exercise. In this case, when estimating the occupant's physical state based on the occupant's biological signal, it can be easily estimated that the occupant is not suitable for passive motion.
　そして、ステップＳ４０４～Ｓ４０６では、第３実施形態のステップＳ２０３～Ｓ２０５と同様の処理が行われる。すなわち、ステップＳ４０３における推定の結果、乗員の身体状態が受動運動に適さない状態であると推定された場合（ステップＳ４０４＝Ｙｅｓ）には、乗員の受動運動による運動量が小さくなるように、各エアバック２１，２２，１１，１２，１３が制御され（ステップＳ４０５）、一方、乗員が受動運動に適した状態であると推定された場合（ステップＳ４０４＝Ｎｏ）には、乗員の受動運動による運動量が大きくなるように、各エアバック２１，２２，１１，１２，１３が制御される（ステップＳ４０６）。 In steps S404 to S406, processing similar to that in steps S203 to S205 of the third embodiment is performed. That is, as a result of the estimation in step S403, when it is estimated that the occupant's physical condition is not suitable for passive exercise (step S404 = Yes), each air amount is reduced so that the amount of exercise by the occupant's passive exercise becomes small. When the backs 21, 22, 11, 12, and 13 are controlled (step S405), on the other hand, when it is estimated that the occupant is in a state suitable for passive motion (step S404 = No), the amount of exercise by the occupant's passive motion The air bags 21, 22, 11, 12, and 13 are controlled so as to increase (step S406).
　ステップＳ４０７では、身体状態推定機能により、ステップＳ４０３で推定した乗員の身体状態をデータベース４００に記憶する処理が行われる。これにより、次回処理において、今回処理で推定した乗員の身体状態を含む履歴情報を加味して、乗員の身体状態が推定されることとなる。 In step S407, a process of storing the occupant's physical condition estimated in step S403 in the database 400 is performed by the physical condition estimation function. Thus, in the next process, the occupant's physical condition is estimated in consideration of the history information including the occupant's physical condition estimated in the current process.
　以上のように、第５実施形態では、乗員の身体情報の履歴情報を取得し、取得した履歴情報を加味して、乗員の身体状態を推定する。これにより、第５実施形態では、第３実施形態の効果に加えて、乗員の現在の身体状態だけではなく、乗員の過去の身体状態も加味して、乗員の身体状態をより適切に推定することができるという効果を奏することができる。 As described above, in the fifth embodiment, the history information of the occupant's physical information is acquired, and the occupant's physical state is estimated in consideration of the acquired history information. As a result, in the fifth embodiment, in addition to the effects of the third embodiment, not only the current physical state of the occupant but also the past physical state of the occupant are considered, and the physical state of the occupant is estimated more appropriately. The effect that it is possible can be produced.
　≪第６実施形態≫
　続いて、本発明の第６実施形態について説明する。図１３は、第６実施形態に係るシート装置１００の制御システムを備えた車両１ｄの構成を示すブロック図である。第６実施形態に係る車両１ｄは、以下に説明する点以外は、第３実施形態と同様の構成を有し、また、以下に説明するように動作すること以外は、第３実施形態と同様に動作する。 << Sixth Embodiment >>
Subsequently, a sixth embodiment of the present invention will be described. FIG. 13 is a block diagram illustrating a configuration of a vehicle 1d including the control system for the seat device 100 according to the sixth embodiment. The vehicle 1d according to the sixth embodiment has the same configuration as that of the third embodiment except for the points described below, and is the same as that of the third embodiment except that the vehicle 1d operates as described below. To work.
　図１３に示すように、第６実施形態に係る車両１ｄは、シート装置１００と制御装置３００とを備える。第６実施形態に係る制御装置３００は、現在時刻に基づいて乗員の身体状態を推定する。たとえば、制御装置３００の身体状態推定機能は、一般に人の運動能力が朝よりも夜のほうが高いため、時刻が朝である場合には、乗員の身体状態を受動運動に適さない状態であると推定し、反対に、時刻が夜である場合には、乗員の身体状態を受動運動に適した状態であると推定することができる。 As shown in FIG. 13, a vehicle 1 d according to the sixth embodiment includes a seat device 100 and a control device 300. The control device 300 according to the sixth embodiment estimates the occupant's physical state based on the current time. For example, the body state estimation function of the control device 300 is generally a state in which a person's physical ability is higher in the night than in the morning, so that when the time is in the morning, the occupant's physical state is not suitable for passive exercise. In contrast, when the time is night, it is possible to estimate that the occupant's physical condition is suitable for passive exercise.
　次に、第６実施形態に係るシート装置１００の制御処理について説明する。図１４は、第６実施形態に係るシート装置１００の制御処理を示すフローチャートである。 Next, control processing of the sheet apparatus 100 according to the sixth embodiment will be described. FIG. 14 is a flowchart showing a control process of the sheet apparatus 100 according to the sixth embodiment.
　まず、ステップＳ５０１では、制御装置３００の身体状態推定機能により、現在時刻に基づいて、乗員の身体状態の推定が行われる。たとえば、身体状態推定機能は、時刻が朝である場合には、乗員は受動運動に適さない状態であると推定し、反対に、時刻が夜である場合には、乗員は受動運動に適した状態であると推定する。 First, in step S501, the body state of the occupant is estimated based on the current time by the body state estimation function of the control device 300. For example, if the time is in the morning, the body state estimation function estimates that the occupant is not suitable for passive exercise, and conversely, if the time is at night, the occupant is suitable for passive exercise. Presumed to be in a state.
　そして、ステップＳ５０２～Ｓ５０４は、第３実施形態のステップＳ２０３～Ｓ２０５と同様の処理が行われる。すなわち、ステップＳ５０１における推定の結果、乗員が受動運動に適さない状態であると推定された場合（ステップＳ５０２＝Ｙｅｓ）には、乗員の受動運動による運動量が小さくなるように、各エアバック２１，２２，１１，１２，１３が制御され（ステップＳ５０３）、乗員が受動運動に適した状態であると推定された場合（ステップＳ５０２＝Ｎｏ）には、乗員の受動運動による運動量が大きくなるように、各エアバック２１，２２，１１，１２，１３が制御される（ステップＳ５０４）。 In steps S502 to S504, processing similar to that in steps S203 to S205 of the third embodiment is performed. That is, as a result of the estimation in step S501, when it is estimated that the occupant is not suitable for passive motion (step S502 = Yes), each airbag 21, 22, 11, 12, and 13 are controlled (step S503), and when it is estimated that the occupant is in a state suitable for passive exercise (step S502 = No), the amount of exercise by the occupant is increased. The airbags 21, 22, 11, 12, 13 are controlled (step S504).
　以上のように、第６実施形態では、１日における人間の身体状態の傾向から、現在時刻における乗員の身体状態を推定する。このように、第６実施形態では、一般的に取得が容易な現在時刻に基づいて、乗員の身体状態を推定することができるため、第３実施形態の効果に加えて、乗員の生体信号を検出する生体信号検出装置５００を省略することができるため、シート装置１００の制御システムの省スペース化、低コスト化を図ることができる。 As described above, in the sixth embodiment, the occupant's physical condition at the current time is estimated from the tendency of the human physical condition in one day. As described above, in the sixth embodiment, since the occupant's physical state can be estimated based on the current time that is generally easy to acquire, in addition to the effects of the third embodiment, the occupant's biological signal is Since the biological signal detection device 500 to be detected can be omitted, the control system of the seat device 100 can be reduced in space and cost.

As a result, when the occupant is in a state not suitable for passive exercise, the posture of the occupant can be prevented from changing more than a certain amount during traveling of the vehicle, and the occupant's body can be supported appropriately. In addition, when the occupant is in a state suitable for passive exercise, the control device 300 performs control so that the occupant can obtain a certain amount of exercise by returning these support parts to the normal state.
　次に、第７実施形態に係るシート装置１００ａの制御処理について説明する。図１５は、第７実施形態のシート装置１００ａの制御処理を示すフローチャートである。 Next, control processing of the sheet apparatus 100a according to the seventh embodiment will be described. FIG. 15 is a flowchart illustrating a control process of the sheet apparatus 100a according to the seventh embodiment.
　ステップＳ６０１～Ｓ６０４では、第３実施形態のステップＳ２０１～Ｓ２０４と同様に、乗員の生体信号の検出が行われ（ステップＳ６０１）、検出された乗員の生体信号に基づいて、乗員の身体状態の推定が行われる（ステップＳ６０２）。そして、乗員の身体状態が受動運動に適さない状態であると推定された場合には（ステップＳ６０３＝Ｙｅｓ）、乗員の受動運動による運動量が小さくなるように、各エアバック２１，２２，１１，１２，１３の制御が行われる（ステップＳ６０４）。 In steps S601 to S604, the occupant's biological signal is detected (step S601), as in steps S201 to S204 of the third embodiment, and the occupant's body state is estimated based on the detected occupant's biological signal.
