Description

本発明は、車両の駐車を支援するシステム、設備、装置、車両及び方法に関する。   The present invention relates to a system, equipment, device, vehicle, and method for supporting parking of a vehicle.

従来、車両の駐車を支援する装置としては、例えば特許文献1に見られるものが知られている。この装置では、非接触給電を行う駐車領域に車両を後ろ向きに駐車させる場合に、車両のサイドミラーの上辺側のLEDと下辺側のLEDとを点灯させる。この場合、点灯させる上下のLEDを結ぶ線が、車両を適正な目標位置に駐車させた場合に、サイドミラーに写る駐車領域の側方のガイド線に一致するように、点灯させれる上下のLEDが選定される。   2. Description of the Related Art Conventionally, as an apparatus for assisting parking of a vehicle, for example, a device found in Patent Document 1 is known. In this apparatus, when the vehicle is parked backward in a parking area where non-contact power feeding is performed, the upper side LED and the lower side LED of the side mirror of the vehicle are turned on. In this case, the upper and lower LEDs that are lit so that the line connecting the upper and lower LEDs to be lit coincides with the guide line on the side of the parking area that appears in the side mirror when the vehicle is parked at an appropriate target position. Is selected.

特開2013−75612号公報JP2013-75612A

特許文献1に見られる装置では、車両を駐車領域に駐車させる場合に、運転車がサイドミラーを見ることを前提としている。しかしながら、例えば車両を後ろ向きに駐車させる場合には、運転者は、後方確認のために車両の後側方を直接的に見ることを頻繁にもしくは継続的に行うことが多い。   In the apparatus shown in Patent Document 1, it is assumed that the driving vehicle sees the side mirror when the vehicle is parked in the parking area. However, for example, when the vehicle is parked backward, the driver often frequently or continuously looks directly at the rear side of the vehicle for backward confirmation.

このような場合には、運転者は、サイドミラーから目を離すので、上下のLEDを結ぶ線分と、ガイド線との位置関係を認識できない。ひいては、当該位置関係に基づく駐車支援を受けることができない状況が生じやすい。   In such a case, since the driver keeps an eye on the side mirror, the driver cannot recognize the positional relationship between the line segment connecting the upper and lower LEDs and the guide line. Eventually, a situation in which parking assistance based on the positional relationship cannot be obtained tends to occur.

また、サイドミラー上で、上下のLEDを結ぶ線分と、ガイド線とを揃えるためには駐車領域に対する車両の前後方向の向きをガイド線と同方向に精度よく揃える必要がある。しかるに、このようにするためには、車両の慎重なハンドル操作もしくは熟練したハンドル操作を必要とする。   Further, in order to align the line connecting the upper and lower LEDs with the guide line on the side mirror, it is necessary to accurately align the vehicle front-rear direction with respect to the parking area in the same direction as the guide line. However, in order to do so, a careful steering operation or skilled steering operation of the vehicle is required.

このため、運転者は、特許文献1に見られる装置を、駐車支援のために利用しづらいという不都合がある。   For this reason, there is an inconvenience that it is difficult for the driver to use the device shown in Patent Document 1 for parking assistance.

本発明は、かかる背景に鑑みてなされたものであり、運転者が車両を適切な領域に駐車させることを容易に行うことができるように当該駐車を支援し得るシステム、設備、装置、車両及び方法を提供することを目的とする。   The present invention has been made in view of such a background, and a system, equipment, device, vehicle, and vehicle that can assist the driver to easily park the vehicle in an appropriate area. It aims to provide a method.

本発明の駐車支援システムは、上記目的を達成するために、車両の駐車領域の周辺の領域に第1投光像を投光し得るように構成された第1投光装置と、前記車両の周辺の領域に第2投光像を投光し得るように構成された第2投光装置とを備え、前記第1投光装置及び前記第2投光装置は、前記駐車領域への前記車両の進入中に、該車両が前記駐車領域内の許容領域から逸脱した状態では、該車両が前記許容領域に近づくに伴い、前記第1投光像と前記第2投光像とが互いに離れた状態から接近し、且つ、該車両が、前記許容領域に収まった状態で、前記第1投光像及び前記第2投光像が互いに重なり合うように、又は、前記第1投光像及び前記第2投光像の一方が他方に内包されるように、前記第1投光像及び前記第2投光像のそれぞれを前記車両の運転者が目視し得る領域に投光するように構成されていることを特徴とする(第1発明)。   In order to achieve the above object, a parking support system according to the present invention is configured to project a first light projection device configured to project a first light projection image in an area around a parking area of the vehicle, A second light projecting device configured to project a second light projection image in a peripheral region, wherein the first light projecting device and the second light projecting device include the vehicle to the parking region. When the vehicle departs from the permissible area in the parking area while the vehicle enters, the first projected image and the second projected image are separated from each other as the vehicle approaches the permitted area. The first projected image and the second projected image overlap each other, or the first projected image and the second projected image are close to each other and the vehicle is within the allowable area. Each of the first projected image and the second projected image is placed in front so that one of the two projected images is included in the other. Characterized in that it is configured so as to project to the area where the driver of the vehicle can visually (first invention).

なお、本発明において、第1投光像及び第2投光像のそれぞれは、照射光によって、その存在領域(内側領域)が、外側の領域と視覚的に区画された像を意味する。各投光像の存在領域(内側領域)は、光が照射されていない部分を含み得る。   In the present invention, each of the first projected image and the second projected image means an image in which the existence area (inner area) is visually divided from the outer area by the irradiation light. The existence area (inner area) of each projected image may include a portion that is not irradiated with light.

また、本発明において、運転者が目視可能な領域というのは、該運転者がその視線方向を適当に調整することで、該運転者の目に直接的に投影され得る領域を意味する。   In the present invention, the region that can be visually recognized by the driver means a region that can be projected directly to the driver's eyes by appropriately adjusting the direction of the line of sight of the driver.

上記第1発明によれば、運転者は、前記第1投光像及び第2投光像を適宜、目視しつつ、前記第1投光像及び第2投光像を接近させていくように車両を移動させるだけで、該車両を前記許容領域内に近づけていくことができる。   According to the first aspect of the invention, the driver makes the first projected image and the second projected image approach each other while appropriately viewing the first projected image and the second projected image. By simply moving the vehicle, the vehicle can be brought closer to the allowable area.

さらに、最終的に第1投光像及び第2投光像が互いに重なり合うように、又は、第1投光像及び第2投光像の一方が他方に内包されるように、車両を移動させることで、車両を駐車領域内の許容領域に収めることができる。   Further, the vehicle is moved so that the first projected image and the second projected image are finally overlapped with each other, or one of the first projected image and the second projected image is included in the other. Thus, the vehicle can be accommodated in the allowable area within the parking area.

この場合、運転者は、目視によって、第1投光像及び第2投光像が互いに接近し、さらには互いに重なり合うか、又は、第1投光像及び第2投光像の一方が他方に内包されることを目標として、車両を移動させればよいので、該車両を駐車領域内の適正な領域たる前記許容領域に容易に移動できる。   In this case, the driver visually observes that the first projection image and the second projection image approach each other and further overlap each other, or one of the first projection image and the second projection image is on the other side. Since it is only necessary to move the vehicle with the goal of being included, the vehicle can be easily moved to the permissible area, which is an appropriate area within the parking area.

上記第1発明では、前記第1投光像及び第2投光像のうちの一方の投光像は、他方の投光像の内側に収まる大きさであり、前記第1投光装置及び前記第2投光装置は、前記車両が前記許容領域に収まった状態で、前記一方の投光像が前記他方の投光像に内包されるように前記第1投光像及び前記第2投光像のそれぞれを投光するように構成されていることが好ましい(第2発明)。   In the first invention, one of the first projected image and the second projected image is sized to fit inside the other projected image, and the first projected device and the The second projector projects the first and second projection images so that the one projection image is included in the other projection image in a state where the vehicle is within the allowable area. It is preferable that each image is projected (second invention).

これによれば、運転者は、前記一方の投光像を前記他方の投光像に内包させることを目標として、車両を移動させるだけで、該車両を適正な許容領域に移動できる。このため、運転者は、駐車領域に対する車両の姿勢(ヨー方向の姿勢)をさほど厳密に注意することなく車両を移動できる。ひいては、前記許容領域への車両の移動をより容易に行うことの効果を高められる。   According to this, the driver can move the vehicle to an appropriate permissible region only by moving the vehicle with the goal of including the one projected image in the other projected image. For this reason, the driver can move the vehicle without paying close attention to the posture of the vehicle with respect to the parking area (posture in the yaw direction). As a result, the effect of more easily moving the vehicle to the permissible area can be enhanced.

上記第1発明又は第2発明では、前記第1投光装置及び第2投光装置は、前記第1投光像に対する前記第2投光像の相対移動量が、前記許容領域に対する前記車両の相対移動量に一致するように、前記第1投光像及び第2投光像のそれぞれを投光するように構成されていることが好ましい(第3発明)。   In the first invention or the second invention, the first light projecting device and the second light projecting device may be configured such that a relative movement amount of the second light projected image with respect to the first light projected image is a value of the vehicle with respect to the allowable region. It is preferable that each of the first projection image and the second projection image is projected so as to coincide with the relative movement amount (third invention).

これによれば、運転者は、駐車領域への車両の進入中に、前記第1投光像に対する前記第2投光像の相対移動量を視覚的に認識することで、車両が許容領域に対してどの程度近づいているかを容易に認識できる。ひいては、前記許容領域への車両の移動をより容易に行うことの効果を高められる。   According to this, the driver visually recognizes the relative movement amount of the second projection image with respect to the first projection image while the vehicle enters the parking area, so that the vehicle enters the allowable region. It is easy to recognize how close they are. As a result, the effect of more easily moving the vehicle to the permissible area can be enhanced.

上記第1〜第3発明では、前記第1投光装置は、前記駐車領域に対する前記第1投光像の相対位置を一定に維持するように該第1投光像を投光するように構成され、前記第2投光装置は、前記車両に対する前記第2投光像の相対位置を一定に維持するように該第2投光像を投光するように構成されているという態様を採用し得る(第4発明)。   In the first to third aspects of the invention, the first light projecting device is configured to project the first light projection image so as to maintain a constant relative position of the first light projection image with respect to the parking area. The second projector is configured to project the second projected image so that the relative position of the second projected image with respect to the vehicle is maintained constant. Obtained (fourth invention).

これによれば、前記第1投光像及び第2投光像の相対的な位置関係は、車両と前記許容領域との位置関係に対応するものとなる。このため、前記第3発明と同様に前記第1投光像及び第2投光像のそれぞれを投光することを容易に実現できる。そして、第3発明と同様の効果を奏することができる。   According to this, the relative positional relationship between the first projected image and the second projected image corresponds to the positional relationship between the vehicle and the allowable area. For this reason, it is possible to easily project each of the first projected image and the second projected image as in the third invention. And the effect similar to 3rd invention can be show | played.

また、第1投光像が駐車領域に対して静止していると共に、第2投光像が、車両と一体に動くので、運転者は、第1投光像及び第2投光像の目視によって、前記許容領域に対する車両の位置関係をより一層容易に認識しやすくなる。   In addition, the first projection image is stationary with respect to the parking area, and the second projection image moves together with the vehicle, so that the driver can visually check the first projection image and the second projection image. This makes it easier to recognize the positional relationship of the vehicle with respect to the allowable area.

上記第1〜第4発明では、前記第2投光装置は、前記車両に対してあらかじめ定められた所定の相対位置に向かって前記第2投光像を投光するように前記車両に搭載されており、前記第1投光装置は、前記所定の相対位置と前記車両のサイズとを示す情報を前記車両との通信によって取得し、該情報を用いて前記第1投光像の投光位置を決定する機能を含み、当該決定した投光位置に前記第1投光像を投光するように構成されているという態様を採用し得る(第5発明)。   In the first to fourth aspects of the invention, the second light projecting device is mounted on the vehicle so as to project the second light projection image toward a predetermined relative position determined in advance with respect to the vehicle. The first light projecting device acquires information indicating the predetermined relative position and the size of the vehicle through communication with the vehicle, and uses the information to project the light projecting position of the first light projected image. The aspect which is comprised so that the said 1st light projection image may be projected to the determined light projection position can be employ | adopted (5th invention).

これによれば、車両に搭載される前記第2投光装置を簡易且つ安価に構成し得る。また、車種等に応じて、車両に対する第2投光像の投光位置が異なる場合であっても、該第2投光像の投光位置に適合させた位置に第1投光像を投光できる。   According to this, the said 2nd light projection apparatus mounted in a vehicle can be comprised simply and cheaply. Further, even if the light projection position of the second light projection image with respect to the vehicle differs depending on the vehicle type or the like, the first light projection image is projected at a position adapted to the light projection position of the second light projection image. Can shine.

上記第1〜第5発明では、前記第2投光装置は、前記車両の運転席側の側方の後方領域に前記第2投光像を投光するように構成され得る(第6発明)。   In the first to fifth aspects of the invention, the second light projecting device may be configured to project the second light projection image in a rear region on the side of the driver's seat side of the vehicle (sixth aspect). .

これによれば、車両を前記駐車領域に後向きに駐車させる場合に、運転者は、車両の運転席側の側方の後方領域の状況を目視で確認することで、前記第2投光像を見ることができる。また、運転者は、少なくとも駐車領域への車両の進入途中では、前記2投光像と共に、前記第1投光像を、運転席側の側方の後方領域で目視し得ることとなる。   According to this, when the vehicle is parked rearward in the parking area, the driver visually confirms the situation of the rear area on the side of the driver's seat side of the vehicle, so that the second projected image is displayed. Can see. In addition, at least during the approach of the vehicle to the parking area, the driver can view the first projection image together with the two projection images in the rear area on the side of the driver seat.

このため、運転者は、車両を前記駐車領域に後向きに駐車させる場合に、該車両の許容領域への移動(後退)を、通常の駐車時の場合と同様の所作で容易に行なえる。   For this reason, when the driver parks the vehicle backward in the parking area, the driver can easily move (retreat) the vehicle to the permissible area with the same operation as in normal parking.

上記第6発明では、前記第2投光像を投光する領域は、前記車両に搭載された後側方視認装置の視野領域に含まれる領域であることが好ましい(第7発明)。   In the sixth aspect of the present invention, it is preferable that the region where the second projected image is projected is a region included in a visual field region of a rear side viewing device mounted on the vehicle (seventh aspect).

これによれば、車両を前記駐車領域に後向きに駐車させる場合に、運転者は、適宜、運転席側の後側方視認装置(例えばサイドミラー)によって、前記第1投光像及び第2投光像を見ることも可能となる。ひいては、前記許容領域への車両の移動(後退)を容易に行なえる効果をより一層高めることができる。   According to this, when the vehicle is parked rearward in the parking area, the driver appropriately uses the rear side visual recognition device (for example, a side mirror) on the driver's seat side for the first projection image and the second projection image. It is also possible to see a light image. As a result, the effect of easily moving (retreating) the vehicle to the allowable area can be further enhanced.

In this case, the permissible area is an area set such that power transmission efficiency from the power transmission unit to the power receiving unit is a predetermined value or more in a state where the vehicle is within the permissible area, or the power transmission unit It is preferable that the region is set so that the amount of leakage in the transmission energy output from the terminal is equal to or less than a predetermined value (eighth invention).

これによれば、駐車領域のうち、前記送電効率が所定値以上の高効率となり、あるいは、前記送電エネルギーの漏洩量が所定値以下の低量となるような領域(前記許容領域)に車両を駐車させることを適切に支援できる。ひいては、前記非接触給電を効率よく、もしくは、低漏洩量で行なえる。   According to this, in the parking area, the vehicle is placed in an area (the permissible area) in which the power transmission efficiency is a high efficiency equal to or higher than a predetermined value, or a leakage amount of the power transmission energy is a low amount equal to or lower than a predetermined value. Appropriate support for parking. As a result, the non-contact power feeding can be performed efficiently or with a low leakage amount.

The first projected image and the second projected image are projected so that the centers of the first projected image and the second projected image coincide with each other in the state. It is preferable (9th invention).

これによれば、前記運転者は、第1投光像及び第2投光像のそれぞれの中心を一致させることを目標として、車両を移動させることで、車両を非接触給電のための最適な位置もしくはそれに近い位置に駐車できる。   According to this, the driver moves the vehicle with the goal of making the centers of the first and second projected images coincide with each other, thereby making the vehicle optimal for non-contact power feeding. You can park at or near the location.

レーザ光源11は、1つ又は複数の発光素子(例えば発光ダイオード)により構成される。該レーザ光源11は、制御部12の制御によって、駐車領域PAの周辺の地面の所定領域に駐車支援用の投光像15を投光するようにレーザ光を地面に照射する。なお、投光像15は、本発明における第1投光像に相当する。   The laser light source 11 includes one or a plurality of light emitting elements (for example, light emitting diodes). Under the control of the control unit 12, the laser light source 11 irradiates the ground with laser light so as to project a parking assistance light projection image 15 onto a predetermined area on the ground around the parking area PA. The projected image 15 corresponds to the first projected image in the present invention.

本実施形態では、駐車支援用の投光像15(以降、設備側投光像15という)は、図1又は図4に例示する如く、例えば、四角形状の投光像である。この設備側投光像15は、例えば、その外周の輪郭線部分に、所定色のレーザ光を照射することで形成される。   In the present embodiment, the parking support projection image 15 (hereinafter referred to as the facility-side projection image 15) is, for example, a quadrangular projection image as illustrated in FIG. 1 or FIG. The facility-side projected image 15 is formed, for example, by irradiating a contour line portion on the outer periphery with laser light of a predetermined color.

また、設備側投光像15を形成する領域(投光領域)は、駐車領域PAの周辺のうち、該駐車領域PAに駐車させようとする車両100の運転者が、駐車領域PAへの車両100の進入中に目視可能な領域である。   In addition, the area (light projection area) where the facility-side light projection image 15 is formed is that the driver of the vehicle 100 who wants to park in the parking area PA in the vicinity of the parking area PA This is an area that can be seen during 100 approach.

In addition, the vehicle 100 enters the parking area PA, for example, backwards. For this reason, the laser light source 11 is configured so that the driver of the vehicle 100 can visually observe the facility-side projected image 15 from the driver seat side to the right rear side while the vehicle 100 enters the parking area PA. As shown in FIG. 1, the facility-side projected image 15 is projected onto a region near the right rear portion of the parking area PA. Further, the light projection area of the facility-side light projection image 15 is a visual field range of the side mirror 102R on the driver seat side (right side) of the vehicle 100 as shown in FIG. 4 in a state where the vehicle 100 has entered the parking area PA to some extent. This is the region that will be included in θ.

また、設備側投光像15の投光領域の位置(駐車領域PAに対する相対位置)及び該設備側投光像15のサイズは、駐車領域PAへの車両100の進入開始時又はその直後に、後述する車両情報に応じて、制御部12により決定される。そして、設備側投光像15の投光領域の位置及びサイズは、駐車領域PAへの車両100の進入中は一定に維持される。   In addition, the position of the light-projected area of the facility-side light-projected image 15 (relative position with respect to the parking area PA) and the size of the facility-side light-projected image 15 are set when the vehicle 100 starts to enter the parking area PA or immediately after that. It is determined by the control unit 12 according to vehicle information to be described later. And the position and size of the light projection area | region of the installation side light projection image 15 are maintained constant during approach of the vehicle 100 to the parking area PA.

補足すると、駐車支援用の設備側投光像15の形状は、四角形以外の形状(例えば、四角形以外の多角形状、あるいは、円形状もしくは楕円形状等)であってもよい。また、設備側投光像15は、例えば、その外周の輪郭線の内側の領域の全体もしくは一部にレーザ光の照射部分を有する像であってもよい。あるいは、設備側投光像15は、その外周の輪郭線の外側でのレーザ光の照射パターンによって、該設備側投光像15の領域(輪郭線の内側領域)が外側領域と視覚的に区画された像であってもよい。   Supplementally, the shape of the facility-side projected image 15 for parking assistance may be a shape other than a quadrangle (for example, a polygonal shape other than a quadrangle, a circular shape, an elliptical shape, or the like). The facility-side projected image 15 may be, for example, an image having a laser beam irradiation part in the whole or a part of the inner region of the outer contour line. Alternatively, the facility-side projected image 15 is visually divided from the outer region by the region of the facility-side projected image 15 (the inner region of the contour line) according to the laser light irradiation pattern outside the outer contour line. It may be an image.

As shown in FIG. 1, the power receiving unit 121 is mounted substantially at the center of the bottom of the vehicle body of the vehicle 100. In the present embodiment, the position of the power receiving unit 121 in the vehicle 100 (specifically, the position of the power receiving unit 121 when the vehicle 100 is viewed on the ground) is determined in advance. For example, the center position of the power receiving unit 121 is set to a predetermined distance from the front end of the vehicle 100 to the rear side on the vehicle width center line of the vehicle 100. This is the same not only in the vehicle 100 but also in any vehicle that can use the facility 1.

車両側投光装置110は、図2に示すように、レーザ光源111と該レーザ光源111の作動を制御する制御部112とを含む。   As shown in FIG. 2, the vehicle-side light projecting device 110 includes a laser light source 111 and a control unit 112 that controls the operation of the laser light source 111.

制御部112は、CPU、RAM、ROM、インターフェース回路等を含む電子回路ユニットにより構成される。該制御部112は、実装されるプログムラム又はハードウェア構成によって、レーザ光源111の作動を制御する。また、制御部112は、前記設備側投光装置10の制御部12と無線通信を行い得るように構成されていると共に、充電装置120との間で通信を行い得るように構成されている。   The control unit 112 includes an electronic circuit unit including a CPU, RAM, ROM, interface circuit, and the like. The control unit 112 controls the operation of the laser light source 111 according to a program or hardware configuration to be mounted. The control unit 112 is configured to be able to perform wireless communication with the control unit 12 of the facility-side light projecting device 10 and is configured to be able to communicate with the charging device 120.

この場合、制御部112は、設備側投光装置10の制御部12との通信によって、前記設備側投光像15の投光領域の位置及びサイズを決定するために該制御部12が使用する車両情報、車両100の駐車動作に関する情報、及び車両100のバッテリ(図示省略)の充電状態に関する情報等を送信することが可能である。   In this case, the control unit 112 is used by the control unit 12 to determine the position and size of the projection area of the facility-side projection image 15 through communication with the control unit 12 of the facility-side projection device 10. It is possible to transmit vehicle information, information related to the parking operation of the vehicle 100, information related to the state of charge of the battery (not shown) of the vehicle 100, and the like.

また、制御部112は、充電装置120との通信によって、車両100のバッテリの充電状態に関する情報を取得したり、あるいは、充電装置120の作動に関する指令を該充電装置120に与えることが可能である。   In addition, the control unit 112 can acquire information related to the state of charge of the battery of the vehicle 100 through communication with the charging device 120, or can give the charging device 120 a command regarding the operation of the charging device 120. .

レーザ光源111は、1つ又は複数の発光素子(例えば発光ダイオード)により構成される。該レーザ光源111は、例えば、図3A又は図3Bに示すように、車両100の運転席側(右側)のサイドミラー102Rに取り付けられている。そして、該レーザ光源111は、制御部112の制御によって、車両100の周辺の地面に駐車支援用の投光像115(以降、車両側投光像115ということがある)を投光するようにレーザ光を地面に照射する。なお、投光像115は、本発明における第2投光像に相当する。   The laser light source 111 is configured by one or a plurality of light emitting elements (for example, light emitting diodes). The laser light source 111 is attached to a side mirror 102R on the driver's seat side (right side) of the vehicle 100, for example, as shown in FIG. 3A or 3B. Then, under the control of the control unit 112, the laser light source 111 projects a parking assistance projection image 115 (hereinafter sometimes referred to as a vehicle-side projection image 115) onto the ground around the vehicle 100. Laser light is irradiated to the ground. The projected image 115 corresponds to the second projected image in the present invention.

本実施形態では、車両側投光像115は、図1、図3A、図3B又は図4に例示する如く、前記設備側投光像15よりも小面積の円形状(概ね点状)の投光像である。この車両側投光像115は、例えば、その外周の輪郭線内の領域全体に、所定色のレーザ光を照射することで形成される。この場合、車両側投光装置110のレーザ光源111から出力されるレーザ光の色は、設備側投光装置10のレーザ光源11から出力されるレーザ光の色と異なる色であることが好ましい。   In the present embodiment, the vehicle-side projection image 115 is a circular (generally dotted) projection having a smaller area than the facility-side projection image 15 as illustrated in FIG. 1, FIG. 3A, FIG. 3B, or FIG. It is a light image. The vehicle-side projected image 115 is formed, for example, by irradiating a laser beam of a predetermined color over the entire area within the contour line on the outer periphery thereof. In this case, it is preferable that the color of the laser light output from the laser light source 111 of the vehicle-side light projecting device 110 is different from the color of the laser light output from the laser light source 11 of the facility-side light projecting device 10.

また、車両側投光像115を投光する領域は、車両100の周辺のうち、駐車領域PAへの車両100を駐車させようとしている運転者が目視可能な領域である。   Moreover, the area | region which projects the vehicle side projection image 115 is an area | region which the driver | operator who is going to park the vehicle 100 to the parking area PA among the periphery of the vehicle 100 can visually recognize.

本実施形態では、前記した如く、車両100の右側が運転席側であると共に、駐車領域PAへの車両100の進入は後向きに行われる。このため、レーザ光源111は、車両100の運転者が、運転席側から右後ろ側に車両側投光像115を目視し得るように、図1又は図4に示す如く、車両100の右側方で該車両100の後側の地面の領域に車両側投光像115を投光する。また、その投光領域は、図4に示す如く、車両100の運転席側(右側)のサイドミラー102Rの視野範囲θ内の領域である。   In the present embodiment, as described above, the right side of the vehicle 100 is the driver's seat side, and the vehicle 100 enters the parking area PA backward. Therefore, the laser light source 111 is provided on the right side of the vehicle 100 as shown in FIG. 1 or FIG. 4 so that the driver of the vehicle 100 can view the vehicle-side projection image 115 from the driver seat side to the right rear side. Thus, the vehicle-side projected image 115 is projected onto the ground area on the rear side of the vehicle 100. Further, as shown in FIG. 4, the light projection area is an area within the visual field range θ of the side mirror 102 </ b> R on the driver's seat side (right side) of the vehicle 100.

また、車両側投光像115の投光位置(車両100に対する相対位置)及び該車両側投光像115のサイズは該車両100においてあらかじめ定められている。従って、車両側投光像115の投光位置及びサイズは、駐車領域PAへの車両100の進入中に、車両100に対して一定に維持される。   Further, the light projection position (relative position with respect to the vehicle 100) of the vehicle-side projection image 115 and the size of the vehicle-side projection image 115 are predetermined in the vehicle 100. Therefore, the light projection position and size of the vehicle-side light projection image 115 are kept constant with respect to the vehicle 100 while the vehicle 100 enters the parking area PA.

補足すると、本実施形態では、車両側投光像115は、点状に近い小面積のものであるので、その形状は、円形状以外の任意の形状のものでよい。また、車両側投光像115は、例えば、その外周の輪郭線部分だけがレーザ光の照射部分となっている像であってもよい。   Supplementally, in the present embodiment, the vehicle-side projected image 115 has a small area close to a dot shape, and therefore, the shape thereof may be an arbitrary shape other than a circular shape. Further, the vehicle-side projected image 115 may be an image in which only the outer contour line portion is a laser light irradiation portion, for example.

次に、本実施形態のシステムにおける車両100の駐車及び非接触給電に関する作動を説明する。なお、以降の説明では、車両100のレーザ光源111及び制御部112をそれぞれ、車両側レーザ光源111、車両側制御部112と称し、設備1のレーザ光源11及び制御部12をそれぞれ、設備側レーザ光源11、設備側制御部12と称することがある。   Next, the operation | movement regarding the parking of the vehicle 100 and non-contact electric power feeding in the system of this embodiment is demonstrated. In the following description, the laser light source 111 and the control unit 112 of the vehicle 100 are referred to as the vehicle-side laser light source 111 and the vehicle-side control unit 112, respectively, and the laser light source 11 and the control unit 12 of the facility 1 are respectively referred to as the facility-side laser. Sometimes referred to as the light source 11 and the facility-side control unit 12.

車両100の運転者が駐車領域PAに車両100を駐車させ、さらに、車両100のバッテリの充電を行うとき、図5の左側のフローチャートに示す処理と右側のフローチャートに示す処理とがそれぞれ、車両側制御部112及び設備側制御部12で各々実行される。   When the driver of the vehicle 100 parks the vehicle 100 in the parking area PA and further charges the battery of the vehicle 100, the processing shown in the flowchart on the left side of FIG. It is executed by the control unit 112 and the facility side control unit 12, respectively.

車両100側では、STEP101において、駐車領域PAへの車両100の駐車が開始される状況であるか否か(換言すれば、運転者が車両100を駐車領域PAに駐車させようとしている状況であるか否か)が判断される。   On the vehicle 100 side, in STEP 101, whether or not parking of the vehicle 100 in the parking area PA is started (in other words, the driver is trying to park the vehicle 100 in the parking area PA). Whether or not) is determined.

このSTEP101の判断処理は、運転者の操作情報、車両100の位置情報、あるいは、車両側制御部112と設備側制御部12との間の無線通信等に基づいて行い得る。   The determination processing in STEP 101 can be performed based on driver operation information, position information of the vehicle 100, wireless communication between the vehicle-side control unit 112 and the facility-side control unit 12, or the like.

例えば、運転者が駐車意志を示すスイッチを操作し、もしくは、駐車意志を示す音声を発した場合、あるいは、車両100の現在位置(GPS等に基づき検知された現在位置)が駐車領域PAの近辺の位置に在る状態で、車両100のシフトレバーが後退ポジションに操作された場合、あるいは、車両側制御部112と設備側制御部12との間の無線通信によって、車両100が設備1の駐車領域PAに接近していることが検知された場合等に、STEP100の判断結果が肯定的になるという態様を採用し得る。   For example, when the driver operates a switch indicating parking intention or emits a sound indicating parking intention, or the current position of the vehicle 100 (current position detected based on GPS or the like) is in the vicinity of the parking area PA. When the shift lever of the vehicle 100 is operated to the reverse position in the state where the vehicle 100 is located, or the vehicle 100 parks the facility 1 by wireless communication between the vehicle-side control unit 112 and the facility-side control unit 12. For example, when it is detected that the vehicle is approaching the area PA, it is possible to adopt a mode in which the determination result of STEP 100 becomes positive.

車両側制御部112は、STEP101の判断結果が肯定的になるまで、STEP101の判断処理を繰り返す。そして、STEP101の判断結果が肯定的になると、車両側制御部112は、次に、STEP102において、車両情報を設備側制御部12に送信する。   The vehicle side control unit 112 repeats the determination process of STEP 101 until the determination result of STEP 101 becomes affirmative. And if the judgment result of STEP101 becomes affirmative, the vehicle side control part 112 will transmit vehicle information to the equipment side control part 12 in STEP102 next.

該車両情報は、設備側制御部12が設備側投光像15の投光位置及びサイズを決定するために使用する情報である。本実施形態では、当該車両情報は、車両100の受電部121と地面への車両側投光像115の投光位置との相対的位置関係(車両100の前後方向(車長方向)及び左右方向(車幅方向)での相対的位置関係)を規定し得る情報と、車両側投光像115のサイズを示す情報とが含まれる。   The vehicle information is information used by the facility-side control unit 12 to determine the projection position and size of the facility-side projection image 15. In the present embodiment, the vehicle information includes the relative positional relationship between the power receiving unit 121 of the vehicle 100 and the light projection position of the vehicle-side projected image 115 on the ground (the front-rear direction (vehicle length direction) and the left-right direction of the vehicle 100). Information that can define (relative positional relationship in (vehicle width direction)) and information indicating the size of the vehicle-side projection image 115 are included.

より具体的には、図4を参照して、本実施形態では、当該車両情報は、例えば、車両側レーザ光源111から車両側投光像115の中心点までの車長方向(図4のX軸方向)の距離Lxの値と、車体の右端側面から車両側投光像115の中心点までの車幅方向(図4のY軸方向)の距離Lyの値と、車両100の前端から車両側レーザ光源111までの車長方向の距離Mxの値と、車両100の車幅Wvの値と、車両側投光像115の幅(直径)Dの値とを含む。   More specifically, referring to FIG. 4, in the present embodiment, the vehicle information is, for example, the vehicle length direction from the vehicle-side laser light source 111 to the center point of the vehicle-side projection image 115 (X in FIG. 4). The value of the distance Lx in the axial direction), the value of the distance Ly in the vehicle width direction (Y-axis direction in FIG. 4) from the right end side surface of the vehicle body to the center point of the vehicle-side projected image 115, and the vehicle from the front end of the vehicle 100 The value of the distance Mx in the vehicle length direction to the side laser light source 111, the value of the vehicle width Wv of the vehicle 100, and the value of the width (diameter) D of the vehicle-side projection image 115 are included.

ここで、本実施形態では、車両100における受電部121の位置(車長方向及び車幅方向での位置)は、前記した如くあらかじめ定められている。すなわち、該受電部121の中心位置は、車両100の車幅中心線Cw上で、車両100の前端から所定距離の位置である。このため、上記Lx、Ly、Mx、Wvの値によって、車両100の受電部121の中心位置と地面への車両側投光像115の投光位置との相対的位置関係が規定される。   Here, in this embodiment, the position (position in the vehicle length direction and the vehicle width direction) of the power receiving unit 121 in the vehicle 100 is determined in advance as described above. That is, the center position of the power reception unit 121 is a position at a predetermined distance from the front end of the vehicle 100 on the vehicle width center line Cw of the vehicle 100. For this reason, the relative position relationship between the center position of the power reception unit 121 of the vehicle 100 and the light projection position of the vehicle-side projected image 115 on the ground is defined by the values of Lx, Ly, Mx, and Wv.

補足すると、車両100の受電部121の中心位置と地面への車両側投光像115の投光位置との相対的位置関係を規定し得る車両情報は、上記Lx、Ly、Mx、Wvの値に限られない。例えば、Lx、Mxの値の代わりに、車両100の前端から車両側投光像115の中心点までの車長方向の距離(=Lx+Mx)の値を車両情報の要素として用いてもよい。また、例えばLy、Wvの代わりに、車幅中心線Cwから車両側投光像115の中心点までの車幅方向の距離(=Ly+Wv/2)の値を、車両情報の要素として用いてもよい。また、Lx、Ly、Mx、Wvの代わりに、例えば、受電部121の中心位置から車両側投光像115の中心点までの車長方向の距離及び車幅方向の距離を車両情報の要素として用いてもよい。   Supplementally, vehicle information that can define the relative positional relationship between the center position of the power receiving unit 121 of the vehicle 100 and the light projection position of the vehicle-side light projection image 115 on the ground is the values of Lx, Ly, Mx, and Wv. Not limited to. For example, instead of the values of Lx and Mx, the value of the distance in the vehicle length direction (= Lx + Mx) from the front end of the vehicle 100 to the center point of the vehicle-side projection image 115 may be used as the vehicle information element. Further, for example, instead of Ly and Wv, the value in the vehicle width direction (= Ly + Wv / 2) from the vehicle width center line Cw to the center point of the vehicle-side projected image 115 may be used as an element of vehicle information. Good. Further, instead of Lx, Ly, Mx, and Wv, for example, the distance in the vehicle length direction and the distance in the vehicle width direction from the center position of the power receiving unit 121 to the center point of the vehicle-side projection image 115 are used as elements of vehicle information. It may be used.

車両側制御部112は、さらに、STEP103において、車両側レーザ光源111を制御することで、該車両側レーザ光源111から車両側投光像115を車両100の周辺の地面に投光させる。該車両側投光像115の投光位置と車両100との相対的位置関係は、車両100の駐車領域PAへの進入中に一定の位置関係(図4に示した位置関係)に維持される。   Further, in STEP 103, the vehicle-side control unit 112 controls the vehicle-side laser light source 111 to project the vehicle-side projection image 115 from the vehicle-side laser light source 111 onto the ground around the vehicle 100. The relative positional relationship between the light projection position of the vehicle-side projected image 115 and the vehicle 100 is maintained at a constant positional relationship (the positional relationship shown in FIG. 4) while the vehicle 100 enters the parking area PA. .

一方、設備側制御部12は、車両側制御部112から送信された車両情報を受信すると(STEP1)、該車両情報に基づいて設備側投光像15の投光位置及びサイズを決定する処理をSTEP2で実行する。   On the other hand, when the facility-side control unit 12 receives the vehicle information transmitted from the vehicle-side control unit 112 (STEP 1), the facility-side control unit 12 performs a process of determining the projection position and size of the facility-side projection image 15 based on the vehicle information. Execute in STEP2.

この処理を図4を参照して具体的に説明する。図4において、参照符号AR0を付した矩形枠の破線で示す領域は、設備1の送電部21から車両100の受電部121への非接触給電を行う上で最適な車両100の存在領域(以降、最適車両領域AR0という)を示し、参照符号AR1を付した矩形枠の破線で示す領域は、当該非接触給電を適切に行う上で許容し得る車両100の存在領域(以降、車両許容領域AR1という)を示している。   This process will be specifically described with reference to FIG. In FIG. 4, a region indicated by a broken line of a rectangular frame denoted by reference symbol AR <b> 0 is a region where the vehicle 100 is optimal for performing non-contact power feeding from the power transmission unit 21 of the facility 1 to the power reception unit 121 of the vehicle 100 (hereinafter referred to as “regional region”) , Which is referred to as an optimal vehicle area AR0), and an area indicated by a broken line with a rectangular frame attached with a reference symbol AR1 is an area where the vehicle 100 can be allowed to be properly performed for the non-contact power supply (hereinafter referred to as a vehicle allowable area AR1). It is shown).

最適車両領域AR0は、その幅と長さとが、それぞれ車両100の車幅、車長と一致するサイズの矩形領域である。この最適車両領域AR0に車両100に存在する状態は、例えば送電部21から受電部121への送電効率(送電部21から出力される送電エネルギーの全体に対する受電部121の受電エネルギーの割合)が最大もしくはほぼ最大となる状態である。そして、車両100が最適車両領域AR0に存在する状態での受電部121と設備1の送電部21との相対的位置関係(以降、最適位置関係という)は、上記送電効率の実測データ等に基づいてあらかじめ定められている。そして、該最適位置関係は、設備側制御部12のメモリにあらかじめ記憶保持されている。   The optimum vehicle area AR0 is a rectangular area whose size and width match the vehicle width and length of the vehicle 100, respectively. The state in which the vehicle 100 exists in the optimal vehicle area AR0 is, for example, that the power transmission efficiency from the power transmission unit 21 to the power reception unit 121 is the maximum (the ratio of the power reception energy of the power reception unit 121 to the entire power transmission energy output from the power transmission unit 21). Or, it is almost in the maximum state. The relative positional relationship (hereinafter referred to as the optimal positional relationship) between the power receiving unit 121 and the power transmission unit 21 of the facility 1 in a state where the vehicle 100 is present in the optimal vehicle area AR0 is based on the measured power transmission efficiency data and the like. Predetermined. The optimum positional relationship is stored and held in advance in the memory of the facility-side control unit 12.

また、車両許容領域AR1は、最適車両領域AR0を包含する矩形領域であると共に、該最適車両領域AR0に対して、車両100の前側、後側、右側、及び左側にそれぞれ、所定のずれ量ΔXF、ΔXB、ΔYR、ΔYLだけ拡大させた領域である。この場合、最適車両領域AR0に対する車両許容領域AR1の相対位置及び該車両許容領域AR1のサイズ(面積)を規定するずれ量ΔXF、ΔXB、ΔYR、ΔYLは、車両100が該車両許容領域AR1内に存在する状態で、送電部21から受電部121への送電効率が所定値以上となるように、あるいは、送電部21から出力される送電エネルギーのうちの漏洩分(受電部121で受電されないエネルギー量)が所定値以下となるように、実験等に基づいてあらかじめ定められている。そして、ずれ量ΔXF、ΔXB、ΔYR、ΔYLは、設備側制御部12のメモリに記憶保持されている。   Further, the vehicle allowable area AR1 is a rectangular area that includes the optimum vehicle area AR0, and a predetermined amount of deviation ΔXF on the front side, the rear side, the right side, and the left side of the vehicle 100 with respect to the optimum vehicle area AR0. , ΔXB, ΔYR, ΔYL. In this case, the deviation amounts ΔXF, ΔXB, ΔYR, ΔYL that define the relative position of the vehicle allowable area AR1 with respect to the optimal vehicle area AR0 and the size (area) of the vehicle allowable area AR1 are such that the vehicle 100 is within the vehicle allowable area AR1. In the existing state, the power transmission efficiency from the power transmission unit 21 to the power reception unit 121 is equal to or higher than a predetermined value, or the amount of leakage in the transmission energy output from the power transmission unit 21 (the amount of energy not received by the power reception unit 121) ) Is determined in advance based on experiments and the like so as to be equal to or less than a predetermined value. The deviation amounts ΔXF, ΔXB, ΔYR, ΔYL are stored and held in the memory of the equipment-side control unit 12.

これらのずれ量ΔXF、ΔXB、ΔYR、ΔYLは、換言すれば、送電部21に対する受電部121の相対位置の、前記最適位置関係からの許容位置ずれ量(上記送電効率が所定値以上となるという条件又は上記漏洩分が所定値以下となるという条件を満たす上で許容し得る位置ずれ量)である。以降、ΔXF、ΔXB、ΔYR、ΔYLを位置ずれ許容量という。   In other words, these deviation amounts ΔXF, ΔXB, ΔYR, ΔYL are the allowable positional deviation amounts from the optimum positional relationship of the relative position of the power reception unit 121 with respect to the power transmission unit 21 (the power transmission efficiency is greater than or equal to a predetermined value). This is a positional deviation amount that can be tolerated in order to satisfy the condition or the condition that the leakage amount is a predetermined value or less. Hereinafter, ΔXF, ΔXB, ΔYR, and ΔYL are referred to as allowable positional deviation.

STEP2では、設備側制御部12は、車両情報のうちのLx、Mx、Ly、Wvの値を用いて、次式(1a),(1b)により、設備側投光像15の代表点としての中心点Pの位置(図4に示すX軸及びY軸を座標軸とするXY座標系でのX軸方向位置Px及びY軸方向位置Py)を決定する。

Px=Lx+Mx ……(1a)
Py=Ly+Wv/2 ……(1b)
In STEP 2, the facility-side control unit 12 uses the values of Lx, Mx, Ly, and Wv in the vehicle information as the representative points of the facility-side projected image 15 according to the following expressions (1a) and (1b). The position of the center point P (the X-axis direction position Px and the Y-axis direction position Py in the XY coordinate system having the X axis and the Y axis shown in FIG. 4 as coordinate axes) is determined.

Px = Lx + Mx (1a)
Py = Ly + Wv / 2 (1b)

ここで、図4に示すXY座標系は、前記最適車両領域AR0の前端の辺の中央点を原点O、車長方向をX軸方向、車幅方向をY軸方向とする座標系である。このXY座標系の原点の位置(駐車領域PAでの位置又は送電部21に対する相対位置)は、送電部21と受電部121との前記最適位置関係と、車両100におけるあらかじめ定められた受電部121の位置を示す情報(詳しくは、車両100の前端から受電部121の代表点(例えば中心点)までの車長方向の距離と、車幅中心線Cwから受電部121の代表点までの車幅方向の距離とを特定し得る情報)とから決定される。   Here, the XY coordinate system shown in FIG. 4 is a coordinate system in which the center point of the front end side of the optimum vehicle area AR0 is the origin O, the vehicle length direction is the X-axis direction, and the vehicle width direction is the Y-axis direction. The position of the origin of the XY coordinate system (the position in the parking area PA or the relative position with respect to the power transmission unit 21) is the optimal positional relationship between the power transmission unit 21 and the power reception unit 121 and the predetermined power reception unit 121 in the vehicle 100. (In detail, the distance in the vehicle length direction from the front end of the vehicle 100 to the representative point (for example, the center point) of the power receiving unit 121 and the vehicle width from the vehicle width center line Cw to the representative point of the power receiving unit 121 Information that can specify the distance in the direction).

STEP2では、設備側制御部12はさらに、車両情報のうちのDの値と、前記位置ずれ許容量ΔXF、ΔXB、ΔYR、ΔYLの値とから、次式(2a),(2b)により、車長方向(X軸方向)での設備側投光像15の幅Txと、車幅方向(Y軸方向)での設備側投光像15の幅Tyとをそれぞれ決定する。

Tx=ΔXF+ΔXB+D ……(2a)
Ty=ΔYR+ΔYL+D ……(2b)
In STEP 2, the facility-side control unit 12 further calculates the vehicle according to the following equations (2a) and (2b) from the value of D in the vehicle information and the values of the allowable displacements ΔXF, ΔXB, ΔYR, and ΔYL. A width Tx of the facility-side projected image 15 in the long direction (X-axis direction) and a width Ty of the facility-side projected image 15 in the vehicle width direction (Y-axis direction) are respectively determined.

Tx = ΔXF + ΔXB + D (2a)
Ty = ΔYR + ΔYL + D (2b)

STEP2では、以上の如く、設備側投光像15の投光位置(中心点Pの位置Px,Py)と、サイズ(幅Tx,Ty)とが決定される。   In STEP 2, as described above, the light projection position (position Px, Py of the center point P) and the size (width Tx, Ty) of the facility-side light projection image 15 are determined.

次いで、設備側制御部12は、STEP3において、設備側レーザ光源11を制御することで、上記の如く投光位置(中心点Pの位置Px,Py)とサイズ(幅Tx,Ty)とが決定された設備側投光像15を地面に投光させる。   Next, in STEP 3, the facility-side control unit 12 controls the facility-side laser light source 11 to determine the light projection position (position Px, Py of the center point P) and size (width Tx, Ty) as described above. The facility-side projected image 15 is projected onto the ground.

以上の如く、車両側投光像115と設備側投光像15とが地面に投光された状態で、車両100の運転者が、該車両100を駐車領域PAに進入させていくように車両100を後退させる。このとき、運転者は、随時、車両100の運転席側の後方の地面を見ることで、車両100と一体に動く車両側投光像115を直接的に目視できる。   As described above, in a state where the vehicle-side projected image 115 and the facility-side projected image 15 are projected onto the ground, the vehicle 100 driver causes the vehicle 100 to enter the parking area PA. Move 100 back. At this time, the driver can directly view the vehicle-side projected image 115 that moves together with the vehicle 100 by looking at the ground behind the driver's seat side of the vehicle 100 as needed.

なお、地面に投光された車両側投光像115は、図3A又は図3Bに例示する如く、車両100の運転席側のサイドミラー102Rに定常的に写る。このため、運転者は、該車両側投光像115の投影像を、適宜、該サイドミラー102Rで視認することもできる。   Note that the vehicle-side projected image 115 projected onto the ground is constantly reflected on the side mirror 102R on the driver's seat side of the vehicle 100, as illustrated in FIG. 3A or 3B. For this reason, the driver can also visually recognize the projection image of the vehicle-side projection image 115 with the side mirror 102R as appropriate.

また、駐車領域PAへの車両100の後退中に、車両100の前後方向(車長方向)が、駐車領域PAの前後方向(X軸方向)と概ね揃うようになった状態では、運転者は、車両100の運転席側の後方の地面を見ることで、さらに車両側投光像115の後方側に、設備側投光像15をも目視できる。   In addition, while the vehicle 100 is retreating to the parking area PA, in the state where the front-rear direction (vehicle length direction) of the vehicle 100 is substantially aligned with the front-rear direction (X-axis direction) of the parking area PA, the driver By looking at the ground behind the driver's seat side of the vehicle 100, the facility-side projected image 15 can also be visually observed on the rear side of the vehicle-side projected image 115.

なお、駐車領域PAへの車両100の進入がある程度進行した状態では、設備側投光像15は、図3Bに例示する如く、車両側投光像115と共に、車両100の運転席側のサイドミラー102Rに写るようになる。このため、運転者は、車両側投光像115の投影像に加えて、設備側投光像15の投影像をも、適宜、該サイドミラー102Rで視認できる。   In the state where the vehicle 100 has entered the parking area PA to some extent, the facility-side light projection image 15 and the vehicle-side light projection image 115 are side mirrors on the driver's seat side of the vehicle 100 as illustrated in FIG. 3B. 102R appears. Therefore, the driver can visually recognize the projected image of the facility-side projected image 15 in addition to the projected image of the vehicle-side projected image 115 with the side mirror 102R as appropriate.

ここで、設備側投光像15の投光位置及びサイズが上記の如く決定されるので、車両100が最適車両領域AR0に収まった状態では、車両側投光像115の中心点が設備側投光像15の中心点Pに合致するように、車両側投光像115が設備側投光像15に重なった状態となる。   Here, since the projection position and size of the facility-side projection image 15 are determined as described above, the center point of the vehicle-side projection image 115 is the facility-side projection when the vehicle 100 is within the optimum vehicle area AR0. The vehicle-side projected image 115 is superimposed on the facility-side projected image 15 so as to match the center point P of the light image 15.

また、車両100が車両許容領域AR1内に収まっている状態では、車両側投光像115が設備側投光像15に内包された状態となると共に、車両100が車両許容領域AR1内から逸脱している状態では、車両側投光像115が設備側投光像15から逸脱している状態となる。   Further, in a state where the vehicle 100 is within the vehicle allowable area AR1, the vehicle-side projected image 115 is included in the facility-side projected image 15, and the vehicle 100 deviates from the vehicle allowable area AR1. In this state, the vehicle-side projected image 115 deviates from the facility-side projected image 15.

そして、車両100に対する車両側投光像115の相対位置と、駐車領域PAに対する設備側投光像15の相対位置とは、それぞれ一定に保たれるので、車両側投光像115の中心点と設備側投光像15の中心点Pとの相対的位置関係は、実際の車両100と、最適車両領域AR0に収まった状態を仮想的に想定した車両100との相対的位置関係に一致する。ひいては、車両側投光像115と、設備側投光像15の相対的位置関係が、車両100と車両許容領域AR1との相対的位置関係を示す。   Since the relative position of the vehicle-side projected image 115 with respect to the vehicle 100 and the relative position of the facility-side projected image 15 with respect to the parking area PA are kept constant, respectively, The relative positional relationship with the center point P of the facility-side projected image 15 coincides with the relative positional relationship between the actual vehicle 100 and the vehicle 100 virtually assumed to be in the optimum vehicle area AR0. As a result, the relative positional relationship between the vehicle-side projected image 115 and the facility-side projected image 15 indicates the relative positional relationship between the vehicle 100 and the vehicle allowable area AR1.

従って、車両100が車両許容領域AR1から逸脱した状態から、該車両許容領域AR1内に近づくに伴い、車両側投光像115が、設備側投光像15から逸脱した状態から、設備側投光像15の内側に近づいていく。そして、車両100が、車両許容領域AR1内に収まれば、車両側投光像115が、設備側投光像15の内側に収まる(すなわち、設備側投光像15に内包される)。また、車両100が最適車両領域AR0内に近づくほど、車両側投光像115が、設備側投光像15の中心点Pに近づく。   Accordingly, from the state where the vehicle 100 deviates from the vehicle allowable area AR1, the vehicle-side projected image 115 deviates from the equipment-side projected image 15 as the vehicle 100 approaches the vehicle allowable area AR1. It approaches the inside of the image 15. Then, if the vehicle 100 is within the vehicle allowable area AR1, the vehicle-side projected image 115 is accommodated inside the facility-side projected image 15 (that is, included in the facility-side projected image 15). Further, the closer the vehicle 100 is to the optimum vehicle area AR0, the closer the vehicle-side projection image 115 is to the center point P of the facility-side projection image 15.

そこで、運転者は、車両100の運転席側の後方の車両側投光像115及び設備側投光像15を目視しつつ、あるいは、該車両側投光像115及び設備側投光像15の投影像を適宜、サイドミラー102Rで視認しつつ、車両側投光像115を設備側投光像15の内側の中心点もしくはその近辺に近づけていくように、車両100を駐車領域PAの向かって後退させる。   Therefore, the driver looks at the vehicle-side projected image 115 and the facility-side projected image 15 on the rear side of the driver's seat of the vehicle 100, or the vehicle-side projected image 115 and the facility-side projected image 15. While viewing the projected image with the side mirror 102R as appropriate, the vehicle 100 is moved toward the parking area PA so as to bring the vehicle-side projected image 115 closer to the center point inside the facility-side projected image 15 or the vicinity thereof. Retreat.

そして、運転者は、最終的に、車両側投光像115が、設備側投光像15の内側に達するか、もしくは、設備側投光像15の中心点近辺に達したことを、車両100の運転席側の後方の目視により、もしくはサイドミラー102Rの投影像により確認すると、車両100の移動を終了して、該車両100を駐車させる。   Then, the driver finally confirms that the vehicle-side projection image 115 has reached the inside of the facility-side projection image 15 or has reached the vicinity of the center point of the facility-side projection image 15. If the vehicle 100 is confirmed visually by the rear side of the driver's seat or by the projection image of the side mirror 102R, the movement of the vehicle 100 is terminated and the vehicle 100 is parked.

この場合、運転者は、車両100の運転席側の後方の直接的な目視と、サイドミラー102Rとのいずれでも、車両側投光像115及び設備側投光像15を視認することができる。そして、車両側投光像115と、設備側投光像15の相対的位置関係が、車両100と車両許容領域AR1との相対的位置関係を示す。   In this case, the driver can visually recognize the vehicle-side projected image 115 and the facility-side projected image 15 with either the direct visual observation on the driver seat side rear side of the vehicle 100 or the side mirror 102R. The relative positional relationship between the vehicle-side projected image 115 and the facility-side projected image 15 indicates the relative positional relationship between the vehicle 100 and the vehicle allowable area AR1.

このため、運転者は、車両側投光像115及び設備側投光像15の相対的位置関係の視覚的な認識によって、車両100と車両許容領域AR1との相対的位置関係を容易に認識できる。   For this reason, the driver can easily recognize the relative positional relationship between the vehicle 100 and the vehicle allowable area AR1 by visual recognition of the relative positional relationship between the vehicle-side projected image 115 and the facility-side projected image 15. .

また、車両側投光像115を設備側投光像15の内側に到達させるように、車両100を移動させることで、車両100を車両許容領域AR1に駐車させることが可能であるので、運転者は、駐車領域PAに対する車両100の前後方向の向きをさほど意識的に気にする必要がない(駐車領域PAの前後方向と車両100の前後方向とを極力一致させることをさほど意識する必要がない)。   Further, since the vehicle 100 can be parked in the vehicle allowable area AR1 by moving the vehicle 100 so that the vehicle-side projection image 115 reaches the inside of the facility-side projection image 15, the driver Does not need to care about the direction of the vehicle 100 in the front-rear direction with respect to the parking area PA (there is no need to be so conscious that the front-rear direction of the parking area PA matches the front-rear direction of the vehicle 100 as much as possible). ).

従って、運転者は、車両100を駐車領域PAの車両許容領域AR1内に駐車させるように車両100を移動させることを容易に行なえる。ひいては、運転者は、車両100を駐車領域PAのうちの車両許容領域AR1(すなわち、設備1の送電部21から車両100の受電部121への送電を好適に行い得る領域)に駐車させることを容易に行なえる。   Therefore, the driver can easily move the vehicle 100 so that the vehicle 100 is parked in the vehicle allowable area AR1 of the parking area PA. As a result, the driver parks the vehicle 100 in the vehicle allowable area AR1 in the parking area PA (that is, an area in which power transmission from the power transmission unit 21 of the facility 1 to the power reception unit 121 of the vehicle 100 can be suitably performed). It can be done easily.

図5の説明に戻って、車両側制御部112は、前記STEP103の次に、STEP104において、車両許容領域AR1への車両100の駐車が完了したか否かを判断する。そして、車両側制御部112は、STEP104の判断結果が肯定的になるまで、該判断処理を繰り返す。   Returning to the description of FIG. 5, the vehicle-side control unit 112 determines whether or not parking of the vehicle 100 in the vehicle allowable area AR <b> 1 is completed in STEP 104 after STEP 103. And the vehicle side control part 112 repeats this judgment process until the judgment result of STEP104 becomes affirmative.

上記STEP104の判断処理は、例えば、車両100のシフトレバーの操作状態、あるいは、送電部21及び受電部121の位置関係に関する検知データ等に基づいて行い得る。   The determination process in STEP 104 can be performed based on, for example, detection data regarding the operation state of the shift lever of the vehicle 100 or the positional relationship between the power transmission unit 21 and the power reception unit 121.

例えば、車両100のシフトレバーが、パーキングポジションに操作された場合にSTEP104の判断結果が肯定的になるという態様を採用し得る。   For example, a mode in which the determination result of STEP 104 becomes positive when the shift lever of the vehicle 100 is operated to the parking position can be adopted.

また、例えば、車両100の停車状態で、車両側制御部112から設備側制御部12に、一時的な送電を要求する信号を送信することで、送電部21から一時的な送電を行わせる。そして、送電部21からの一時的な送電中に、所定レベル以上の送電エネルギーを受電部121で受電し得ることを車両100側で検知し得る場合に、STEP104の判断結果が肯定的になるという態様を採用し得る。   Further, for example, when the vehicle 100 is stopped, the vehicle-side control unit 112 transmits a signal requesting temporary power transmission to the facility-side control unit 12, thereby causing the power transmission unit 21 to perform temporary power transmission. When the vehicle 100 can detect that the power receiving unit 121 can receive power transmission energy of a predetermined level or higher during temporary power transmission from the power transmission unit 21, the determination result in STEP 104 is positive. Embodiments may be employed.

また、例えば、車両側投光像115と設備側投光像15との位置関係を認識し得るカメラ等のセンサが設備1側に備えられている場合には、設備側制御部12が、該センサの検出信号により車両側投光像115が設備側投光像15の内側に収まったことが認識できた場合に、その旨を示す信号を、車両側制御部112に送信する。この場合、車両側制御部112が当該信号を受信した場合に、STEP104の判断結果が肯定的になるという態様を採用し得る。   Further, for example, when a sensor such as a camera that can recognize the positional relationship between the vehicle-side projected image 115 and the facility-side projected image 15 is provided on the facility 1 side, the facility-side control unit 12 When it can be recognized that the vehicle-side projection image 115 is within the facility-side projection image 15 by the detection signal of the sensor, a signal indicating that fact is transmitted to the vehicle-side control unit 112. In this case, when the vehicle side control part 112 receives the said signal, the aspect that the judgment result of STEP104 becomes positive can be employ | adopted.

STEP104の判断結果が肯定的になると、車両側制御部112は、次にSTEP105において、車両100の駐車が完了した旨を示す情報を、設備側制御部12に送信する。また、STEP105では、車両側制御部112は、さらに車両側投光像115の投光を停止させるように、車両側レーザ光源111を制御する。これにより、車両側投光像115の投光が停止される。   When the determination result in STEP 104 becomes affirmative, the vehicle-side control unit 112 next transmits information indicating that the parking of the vehicle 100 is completed to the facility-side control unit 12 in STEP 105. Further, in STEP 105, the vehicle-side control unit 112 controls the vehicle-side laser light source 111 so as to further stop the projection of the vehicle-side projection image 115. Thereby, the light projection of the vehicle side light projection image 115 is stopped.

一方、設備側制御部12は、STEP105で送信された情報を受信すると(STEP4)、次にSTEP5において、送電を開始するように送電電力電源装置20に指令する。これにより、設備1の送電電力電源装置20は、送電部21から車両100の受電部121への送電を開始する。   On the other hand, when receiving the information transmitted in STEP 105 (STEP 4), the facility-side control unit 12 instructs the transmitted power power supply device 20 to start power transmission in STEP 5 next. Thereby, the transmission power power supply device 20 of the facility 1 starts power transmission from the power transmission unit 21 to the power reception unit 121 of the vehicle 100.

さらに、STEP5では、設備側制御部12は、送電状況を示す投光像を、駐車支援用の前記設備側投光像15の代わりに、又は該設備側投光像15と共に、駐車領域PAの周辺の地面に投光するように、設備側レーザ光源11を制御する。   Further, in STEP 5, the facility-side control unit 12 uses a light projection image indicating the power transmission status instead of the facility-side light projection image 15 for parking assistance or together with the facility-side light projection image 15 in the parking area PA. The facility-side laser light source 11 is controlled so that light is projected onto the surrounding ground.

当該投光像は、例えば、充電中(非接触給電中)である旨を示す文字データもしくは図形データを含み得る。さらに、例えば、車両側制御部112との通信によって、車両100のバッテリへの充電完了までの所要時間を、設備側制御部12で逐次取得し得る場合には、当該投光像は、該所要時間を示す文字データもしくは図形データを含み得る。   The projected image may include, for example, character data or graphic data indicating that charging is being performed (non-contact power feeding is being performed). Further, for example, when the facility-side control unit 12 can sequentially acquire the time required to complete charging of the battery of the vehicle 100 by communication with the vehicle-side control unit 112, the projected image is Character data or graphic data indicating time may be included.

かかる投光像を地面に投光することにより、車両100の運転者、あるいは、他者は、車両100への非接触給電が行われていることや、該非接触給電が終了するまで、どの程度の時間がかかるかを、当該投光像により容易に認識できる。   By projecting such a projected image on the ground, the driver of the vehicle 100 or another person can determine how much non-contact power feeding to the vehicle 100 is performed or until the non-contact power feeding is completed. Can be easily recognized from the projected image.

なお、当該投光像は、例えば、非接触給電に関する任意の注意情報もしくは警報情報(例えば、駐車領域PAに他者が近づくのを防止するための情報)等を示す文字データもしくは図形データをさらに含み得る。   The projected image further includes, for example, character data or graphic data indicating arbitrary caution information or warning information (for example, information for preventing another person from approaching the parking area PA) regarding the non-contact power supply. May be included.

上記の如く、送電部21からの送電が開始されると、その送電エネルギーは、車両100の受電部121で受電される。この場合、車両100が車両許容領域AR1内に存在しているので、送電部21から受電部121への送電を高効率で行なえる。あるいは、送電部21から出力される送電エネルギーのうちの漏洩分を極力少なくできる。   As described above, when power transmission from the power transmission unit 21 is started, the transmitted energy is received by the power reception unit 121 of the vehicle 100. In this case, since the vehicle 100 exists in the vehicle allowable area AR1, power transmission from the power transmission unit 21 to the power reception unit 121 can be performed with high efficiency. Alternatively, the amount of leakage in the transmission energy output from the power transmission unit 21 can be reduced as much as possible.

そして、受電部121で受電された受電エネルギーは、車両100の充電装置120によって、バッテリに充電される。この充電中において、車両側制御部112は、充電装置120との通信によって、バッテリの充電率(所謂、SOC(State of charge))が、車両100の運転者等により設定された目標値に到達したか否かをSTEP106で判断する。   Then, the received energy received by the power receiving unit 121 is charged to the battery by the charging device 120 of the vehicle 100. During this charging, the vehicle-side control unit 112 reaches the target value set by the driver or the like of the vehicle 100 by the communication with the charging device 120 so that the battery charging rate (so-called SOC (State of charge)) is reached. It is determined in STEP 106 whether or not it has been done.

そして、車両側制御部112は、STEP106の判断結果が肯定的になるまで、STEP106の判断処理を繰り返す。   And the vehicle side control part 112 repeats the determination process of STEP106 until the determination result of STEP106 becomes affirmative.

STEP106の判断結果が肯定的になると、車両側制御部112は、STEP107において、充電装置120に、バッテリの充電を停止すべき旨を指令する。これにより、充電装置120は、受電部121からバッテリへの給電を遮断して、該バッテリの充電を停止する。   If the determination result in STEP 106 becomes affirmative, the vehicle-side control unit 112 instructs the charging device 120 to stop charging the battery in STEP 107. Thereby, charging device 120 cuts off the power supply from power reception unit 121 to the battery, and stops charging the battery.

さらにSTEP107では、車両側制御部112は、バッテリの充電の終了を示す情報を設備側制御部12に送信する。   Further, in STEP 107, the vehicle-side control unit 112 transmits information indicating the end of battery charging to the facility-side control unit 12.

次いで、車両側制御部112は、STEP108において、車両100が駐車領域PAから退去したか否かを判断する。そして、車両側制御部112は、STEP108の判断結果が肯定的になるまで、STEP108の判断処理を繰り返す。   Next, the vehicle control unit 112 determines whether or not the vehicle 100 has left the parking area PA in STEP108. And the vehicle side control part 112 repeats the determination process of STEP108 until the determination result of STEP108 becomes affirmative.

このSTEP108の判断処理は、例えば、車両100の移動状態、車両側制御部112と設備側制御部12との通信等に基づいて行い得る。例えば、運転者が車両100の発進操作を行った場合、あるいは、運転者がシフトレバーをパーキングポジションからドライブボジションに操作した場合、あるいは、運転者が駐車領域PAからの退去を示す音声を発した場合に、STEP108の判断結果が肯定的になるという態様を採用し得る。   The determination process in STEP 108 can be performed based on, for example, the movement state of the vehicle 100, communication between the vehicle-side control unit 112 and the facility-side control unit 12, or the like. For example, when the driver performs a start operation of the vehicle 100, or when the driver operates the shift lever from the parking position to the drive position, or the driver makes a sound indicating that the driver has left the parking area PA. In such a case, an aspect in which the determination result of STEP 108 becomes affirmative can be adopted.

あるいは、車両側制御部112と設備側制御部12との間の無線通信によって、車両100が駐車領域PAから離れていくことが検知された場合に、STEP108の判断結果が肯定的になるという態様を採用し得る。   Alternatively, when the wireless communication between the vehicle-side control unit 112 and the facility-side control unit 12 detects that the vehicle 100 moves away from the parking area PA, the determination result of STEP 108 is positive. Can be adopted.

あるいは、送電部21と受電部121との間の距離を検知し得るセンサが車両100又は設備1に備えられている場合には、該センサにより当該距離が所定値以上になったことが検知された場合に、STEP108の判断結果が肯定的になるという態様を採用し得る。   Alternatively, when the vehicle 100 or the facility 1 is equipped with a sensor that can detect the distance between the power transmission unit 21 and the power reception unit 121, the sensor detects that the distance has reached a predetermined value or more. In such a case, it is possible to adopt a mode in which the determination result of STEP 108 becomes positive.

STEP108の判断結果が肯定的になると、車両側制御部112は、車両100が駐車領域PAから退去する旨の信号を設備側制御部12に送信する(STEP109)。   When the determination result in STEP 108 becomes affirmative, the vehicle-side control unit 112 transmits a signal to the facility-side control unit 12 that the vehicle 100 is leaving the parking area PA (STEP 109).

以上により、駐車領域PAへの車両100の駐車及び車両100のバッテリへの非接触給電に関する車両側制御部112の処理が終了する。   Thus, the processing of the vehicle-side control unit 112 regarding the parking of the vehicle 100 in the parking area PA and the non-contact power supply to the battery of the vehicle 100 ends.

一方、設備側制御部12は、STEP107で送信された情報を受信すると(STEP6)、次にSTEP7において、送電を終了するように送電電力電源装置20に指令する。これにより、設備1の送電電力電源装置20は、送電部21から車両100の受電部121への送電を終了する。   On the other hand, when receiving the information transmitted in STEP 107 (STEP 6), the facility-side control unit 12 instructs the transmission power source 20 to end power transmission in STEP 7. Thereby, the transmission power power supply device 20 of the facility 1 ends the power transmission from the power transmission unit 21 to the power reception unit 121 of the vehicle 100.

さらに、STEP7では、設備側制御部12は、送電終了を示す投光像を、STEP5で投光した投光像の代わりに、駐車領域PAの周辺の地面に投光するように、設備側レーザ光源11を制御する。   Further, in STEP 7, the facility-side control unit 12 projects the light-projected image indicating the end of power transmission on the ground around the parking area PA in place of the light-projected image projected in STEP 5. The light source 11 is controlled.

当該投光像は、送電(非接触給電)を終了することを示す文字データもしくは図形データを含み得る。なお、当該投光像は、その他の任意のサービス情報を含んでもよい。   The projected image may include character data or graphic data indicating that power transmission (contactless power feeding) is to be terminated. The projected image may include other arbitrary service information.

次いで、設備側制御部12は、STEP109で送信された情報を受信すると(STEP8)、次にSTEP9において、駐車領域PAの周辺の地面への投光を停止するように、設備側レーザ光源11を制御する。   Next, upon receiving the information transmitted in STEP 109 (STEP 8), the facility-side control unit 12 next switches the facility-side laser light source 11 to stop projecting light on the ground around the parking area PA in STEP 9. Control.

以上により、駐車領域PAへの車両100の駐車及び車両100のバッテリへの非接触給電に関する設備側制御部12の処理が終了する。   Thus, the processing of the facility-side control unit 12 regarding the parking of the vehicle 100 in the parking area PA and the non-contact power supply to the battery of the vehicle 100 ends.

なお、STEP7では設備側レーザ光源11による新たな投光像の投光を行わずに、投光像の投光を停止するようにしてもよい。この場合には、STEP9の処理は不要である。   In STEP 7, the projection of the projected image may be stopped without projecting a new projected image by the facility-side laser light source 11. In this case, the processing of STEP 9 is not necessary.

以上説明した実施形態によれば、前記した如く、駐車領域PAに車両100を後向きに駐車させる場合に、運転者は、車両100を車両許容領域AR1内に収めるように駐車させることを容易に行なえる。ひいては、設備1の送電部21から車両100の受電部121への送電を、高効率で、あるいは、漏洩分が極力少なくなるように行なえる。   According to the embodiment described above, as described above, when the vehicle 100 is parked rearward in the parking area PA, the driver can easily park the vehicle 100 so as to be within the vehicle allowable area AR1. The As a result, the power transmission from the power transmission unit 21 of the facility 1 to the power reception unit 121 of the vehicle 100 can be performed with high efficiency or so that the amount of leakage is minimized.

なお、本発明は、以上説明した実施形態に限定されるものではない。以下に、他の実施形態をいつくか説明する。前記実施形態では、車両100が右ハンドルの車両である場合(車両100の右側が運転席側である場合)を例にとって説明した。ただし、本発明は、左ハンドルの車両(車両100の左側が運転席側である場合)にも適用できる。この場合には、車両100の左側の地面に車両側投光像115を投光するように車両側投光装置110を構成し、駐車領域PAの周辺のうちの左側の地面に設備側投光像15を投光するように設備側投光装置10を構成することで、左ハンドルの車両100に適用し得る駐車支援システムを実現できる。   The present invention is not limited to the embodiment described above. Some other embodiments will be described below. In the embodiment, the case where the vehicle 100 is a right-hand drive vehicle (the case where the right side of the vehicle 100 is the driver's seat side) has been described as an example. However, the present invention can also be applied to a left-hand drive vehicle (when the left side of the vehicle 100 is the driver's seat side). In this case, the vehicle-side light projection device 110 is configured to project the vehicle-side light projection image 115 on the left ground of the vehicle 100, and the facility-side light projection is performed on the left ground in the vicinity of the parking area PA. By constructing the facility-side light projecting device 10 so as to project the image 15, it is possible to realize a parking support system that can be applied to the left-hand drive vehicle 100.

また、設備側投光装置10を、駐車領域PAの周辺のうちの右側及び左側のいずれに対しても、設備側投光像15を投光し得るように構成すると共に、前記車両情報に、車両100が右ハンドル車であるか左ハンドル車であるかを示す情報を含めてもよい。この場合には、設備側制御部12は、車両100が右ハンドル車であるか左ハンドル車であるかに応じて、設備側投光像15を駐車領域PAの右側及び左側のいずれの側の地面に投光するかを選択的に決定し得る。これにより、右ハンドルの車両100及び左ハンドルの車両100のいずれにも対応し得る駐車支援システムを実現できる。   In addition, the facility-side light projecting device 10 is configured so that the facility-side light projection image 15 can be projected on both the right side and the left side of the periphery of the parking area PA, and the vehicle information includes: Information indicating whether the vehicle 100 is a right-hand drive vehicle or a left-hand drive vehicle may be included. In this case, the facility-side control unit 12 displays the facility-side projection image 15 on either the right side or the left side of the parking area PA depending on whether the vehicle 100 is a right-hand drive vehicle or a left-hand drive vehicle. It can be selectively determined whether to project on the ground. Accordingly, it is possible to realize a parking support system that can handle both the right-hand drive vehicle 100 and the left-hand drive vehicle 100.

また、本発明は、車両100を駐車領域PAに前向きに駐車させる場合についても適用できる。この場合には、車両側投光装置110は、例えば図6に示すように、車両100の運転席側(図示例では右側)の斜め前方の所定位置(車両100に対して一定位置)の地面に車両側投光像115を投光するように構成され得る。また、設備側投光装置10は、図6に例示する如く、駐車領域PAの周辺のうちの右側の地面に設備側投光像15を投光するように構成され得る。この場合、設備側投光像15の投光位置及びサイズの決定の仕方は、前記実施形態と同様でよい。   The present invention can also be applied to the case where the vehicle 100 is parked forward in the parking area PA. In this case, for example, as shown in FIG. 6, the vehicle-side light projecting device 110 is a ground at a predetermined position (a fixed position with respect to the vehicle 100) diagonally forward on the driver's seat side (right side in the illustrated example) of the vehicle 100. The vehicle-side projected image 115 may be projected to the projector. Further, as illustrated in FIG. 6, the facility-side light projecting device 10 can be configured to project the facility-side light projection image 15 on the right ground surface around the parking area PA. In this case, the method of determining the light projection position and size of the facility-side light projection image 15 may be the same as in the above embodiment.

なお、車両側投光装置110は、車両100を後向きに駐車させる場合と、前向きに駐車させる場合とで、車両100に対する車両側投光像115の投光位置を変更し得るように構成されていてもよい。   The vehicle-side light projecting device 110 is configured to change the light projection position of the vehicle-side light projection image 115 with respect to the vehicle 100 when the vehicle 100 is parked backward and when the vehicle 100 is parked forward. May be.

また、前記実施形態では、車両側投光像115が設備側投光像15よりも面積が小さい場合を例にとって説明した。ただし、前記実施形態の場合と逆に、車両側投光像115が設備側投光像15よりも大きい面積を有していてもよい。   In the above-described embodiment, the case where the vehicle-side projected image 115 has a smaller area than the facility-side projected image 15 has been described as an example. However, contrary to the above-described embodiment, the vehicle-side projected image 115 may have a larger area than the facility-side projected image 15.

また、前記実施形態では、車両100が車両許容領域AR1の内側に収まった状態で、車両側投光像115が設備側投光像15に内包されるように、両投光像115,15を投光する場合を例にとって説明した。ただし、車両100が車両許容領域AR1の内側に収まった状態での車両側投光像115と設備側投光像15との位置関係は、前記実施形態の態様に限られない。例えば、車両100が車両許容領域AR1の周縁寄りの位置で該車両許容領域AR1の内側に収まった状態では、車両側投光像115と設備側投光像15とが部分的に重なり合う状態となる態様で、両投光像115,15を投光してもよい。   Further, in the above-described embodiment, both the projected images 115 and 15 are arranged so that the vehicle-side projected image 115 is included in the facility-side projected image 15 in a state where the vehicle 100 is within the vehicle allowable area AR1. The case of projecting light has been described as an example. However, the positional relationship between the vehicle-side projected image 115 and the facility-side projected image 15 in a state where the vehicle 100 is within the vehicle allowable area AR1 is not limited to the aspect of the embodiment. For example, when the vehicle 100 is located inside the vehicle allowable area AR1 at a position near the periphery of the vehicle allowable area AR1, the vehicle-side projected image 115 and the facility-side projected image 15 partially overlap each other. In an embodiment, both the projected images 115 and 15 may be projected.

また、例えば、車両側投光像115の投光位置(車両100に対する相対位置)を適宜変更し得るように車両側投光装置110を構成すると共に、駐車領域PAに対する設備側投光像15の投光位置が固定位置となるように設備側投光装置10を構成することも可能である。この場合には、例えば、送電部21に対する設備側投光像15の相対位置を示す情報を設備側制御部12から車両側制御部112に送信することで、該車両側制御部112が、設備側投光像15の投光位置に整合させるように、車両側投光像115を調整し得る。   In addition, for example, the vehicle-side light projection device 110 is configured so that the light-projecting position (relative position with respect to the vehicle 100) of the vehicle-side light projection image 115 can be changed as appropriate, and It is also possible to configure the facility-side light projecting device 10 so that the light projecting position is a fixed position. In this case, for example, by transmitting information indicating the relative position of the facility-side projection image 15 with respect to the power transmission unit 21 from the facility-side control unit 12 to the vehicle-side control unit 112, the vehicle-side control unit 112 The vehicle-side projected image 115 can be adjusted so as to be aligned with the projected position of the side-projected image 15.

また、前記実施形態では、車両側レーザ光源111が、車両100の運転席側のサイドミラー102Rに搭載されている場合を説明した。ただし、車両側レーザ光源111は、車両100の他の部位に搭載されていてもよい。   In the embodiment, the case where the vehicle-side laser light source 111 is mounted on the side mirror 102 </ b> R on the driver's seat side of the vehicle 100 has been described. However, the vehicle-side laser light source 111 may be mounted on another part of the vehicle 100.

また、車両側投光装置110及び設備側投光装置10のそれぞれの光源は、レーザ光源以外の光源(例えばプロジェクタ等)であってもよい。   The light sources of the vehicle-side light projecting device 110 and the facility-side light projecting device 10 may be light sources other than the laser light source (for example, a projector).

また、前記実施形態では、車両100における受電部121の搭載位置が既定の位置である場合について説明した。ただし、本発明は、車両100における受電部121の搭載位置が車種に応じて異なるような場合にも適用できる。かかる駐車支援システムは、例えば、前記車両情報に、車両100における受電部121の搭載位置を示す情報を含ませると共に、当該搭載位置に関する情報を使用して、設備側投光像15の投光位置を調整するように設備側制御部12を構成することで実現し得る。   In the embodiment, the case where the mounting position of the power receiving unit 121 in the vehicle 100 is the default position has been described.
