In the description of the present application, it should be noted that the azimuth or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. are based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of description of the present application and simplification of the description, and do not indicate or imply that the apparatus or element in question must have a specific azimuth, be configured and operated in a specific azimuth, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring now to fig. 1-2, a vehicle 1 is provided that includes a vehicle body 200 and a seat 300. The seat 300 is disposed in the vehicle body 200, and the seat 300 is provided with a seat belt 10. The seat belt 10 comprises a webbing 11, a tongue plate 12 connected to the webbing 11, and a buckle 13 for latching the tongue plate 12. When the occupant is not wearing the webbing 10, the webbing 11 of the webbing 10 is suspended from a structural member (e.g., the B-pillar 400 shown in fig. 1) on the seat 300 side. In this embodiment, the tongue 12 may be fixedly connected to the webbing 11, and the tongue 12 may move along with the webbing 11. In other embodiments, the tongue 12 may be slidably connected to the webbing 11, and accordingly, a blocking portion (not shown) is provided on the webbing 11, the tongue 12 has a slot (not shown) through which the webbing 11 passes to slidably engage the tongue 12 with the webbing 11, the blocking portion is located below the tongue 12 and wider than the slot, the blocking portion may limit the sliding of the tongue 12 above the blocking portion, and when the webbing 10 is suspended from the structural member, the tongue 12 slides under gravity to the blocking portion, and at this time, the webbing 10 moves by the blocking portion to move the tongue 12. After the occupant sits on the seat 300, the webbing 11 can be put on by pulling the tongue plate 12 so as to straddle the body of the occupant, and then pressing the tongue plate 12 into the buckle 13. After the occupant wears the seat belt 10, the occupant can unlock the seat belt 10 by pressing a button on the buckle 13 to release the tongue plate 12 from the buckle 13. The safety belt in the existing vehicle is fixedly hung on a structural member at one side of a seat, and when an occupant wears the safety belt, the occupant needs to turn around to grab the tongue plate, so that the intelligent level is low and the safety belt is inconvenient to use. In particular, if the driver forgets to wear the seat belt, turning around at a large angle during driving to grab the seat belt tongue brings a great driving risk.

In view of this, the vehicle 1 provided in the present application further includes a seat belt automatic adjustment system 100 provided in the vehicle body 200, the seat belt automatic adjustment system 100 being configured to adjust the height of the tongue 12 of the seat belt 10 on the seat 300 according to the body posture of the occupant, so as to facilitate the occupant to grasp the tongue 12 to wear the seat belt 10. Specifically, the seat belt automatic adjustment system 100 includes a retractor 20, a motor 30, a control module 40, and an occupant monitoring module 70.

The occupant monitoring module 70 is electrically connected to the control module 40, and the occupant monitoring module 70 is configured to collect image information (the image information includes body posture information and body characteristic information, such as facial information, of the occupant) and transmit the collected image information to the control module 40. Illustratively, the occupant monitoring module 70 includes at least one of a DMS (Drive Monitoring System, driver monitoring system) camera, an OMS (Occupancy Monitoring System, occupant monitoring system) camera, and the DMS can not only recognize the face state of the driver, but also check the vigilance of the driver, which helps to improve the safety performance, and can realize a new generation of auxiliary driving functions. The OMS camera is an extension of the DMS camera, and may further enhance the safety performance of the vehicle by monitoring the facial and limb movements of the occupant in the vehicle, for example, the OMS may be used to gather body posture information of the occupant in the vehicle to assist in determining whether the occupant is sitting, has a trend of pulling the seatbelt, wears the seatbelt, and whether a child or pet remains alone. Illustratively, the occupant monitoring module 70 is disposed above a rearview mirror within the vehicle body 200.

The control module 40 is further electrically connected to the motor 30, and the control module 40 is configured to control an operating state (including forward rotation and reverse rotation) of the motor 30. Further, the motor 30 is connected to the retractor 20, the webbing 11 is wound around a spool (not shown) in the corresponding retractor 20, and the motor 30 drives the retractor 20 to push or retract the webbing 11 in response to a control command of the control module 40, thereby achieving the adjustment of the height of the tongue plate 12. Specifically, the control module 40 is configured to determine a target occupant seated on the seat 300 and not wearing the seat belt 10 matched with the seat 300, and control the motor 30 to drive the retractor 20 to rotate according to the body posture information of the occupant collected by the occupant monitoring module 70, so as to drive the webbing 11 to move to adjust the height of the tongue plate 12, thereby facilitating the occupant to quickly pull the tongue plate 12. Further, the control module 40 adjusts the height of the tongue plate 12 by performing a seat belt automatic adjustment method provided in the embodiments of the present application, which will be described in detail below. Wherein the target seat includes a front seat in the vehicle 1. The control module 40 may be a vehicle controller of the vehicle 1, or may be a control device such as a micro control unit (Microcontroller Unit, MCU), a single chip microcomputer, a digital signal processor (Digital Signal Processing, DSP) or the like. The retractor 20, the motor 30, and the control module 40 may all be disposed in a structural member (e.g., a B-pillar) on one side of the seat 300.

Optionally, the automatic adjustment system 100 further includes a seating sensor 50 and a buckle sensor 60 electrically connected to the control module 40, where the seating sensor 50 is disposed below the cushion of the seat 300, and the seating sensor 50 is configured to detect a load of the seat 300 and output a corresponding load detection signal to the control module 40, so that the control module 40 determines whether an occupant sits on the seat 300. The buckle sensor 60 is disposed in the buckle 13, and the buckle sensor 60 is configured to detect a locking state of the buckle 13 and output a corresponding locking state detection signal to the control module 40, so that the control module 40 can determine whether the tongue plate 12 is inserted into the buckle 13.

Referring to fig. 3, fig. 3 is a flowchart of an automatic adjustment method for a seat belt, provided in the present application, the automatic adjustment method for a seat belt specifically includes the following steps:

step 610, monitoring whether an occupant is seated on the target seat 300 while the vehicle 1 is in the activated state. If an occupant is seated on the target seat 300, step 620 is performed, otherwise, step 610 is returned to, and monitoring whether an occupant is seated on the target seat 300 is continued.

Since the seat belt 10, which is matched with the front seat 300 in the vehicle 1, is hung on the B pillar, adjustment is facilitated. Thus, the target seat 300 is preferably a driver seat and/or a passenger seat in the front row. Of course, in other embodiments, the target seat 300 may also include a rear seat.

Illustratively, the control module 40 may determine whether an occupant is seated on the target seat 300 based on the load detection signal output by the seating sensor 50 and/or the image information collected by the occupant monitoring module 70. In the present embodiment, the seat belt automatic adjustment system 100 is automatically started after the vehicle 1 is started, that is, when the vehicle 1 is started, the control module 40 starts to execute the seat belt automatic adjustment method. Alternatively, the occupant may turn off the seat belt automatic adjustment function by setting a center-control PAD (also referred to as a vehicle-mounted controller), thereby causing the control module 40 to stop executing the seat belt automatic adjustment method. Alternatively, the control module 40 may start executing the seat belt automatic adjustment method when a preset trigger condition is satisfied, otherwise, not execute the seat belt automatic adjustment method. For example, the preset trigger conditions may include, but are not limited to, at least one of the following conditions: an unlock signal of the vehicle 1, an occupant opening a door (which may be any door on the vehicle 1), an occupant closing a door, and the like are received. Generally, when the vehicle starts traveling, no more passengers are seated, and therefore, the control module 40 may perform step 610 only during the period from when the vehicle 1 starts traveling to when the vehicle 1 starts traveling, that is, if no passenger is seated on the target seat 300 is detected when the vehicle 1 starts traveling, it may be determined that no more passengers are seated on the target seat 300, that is, it may not return to step 610, so that system resources and energy resources may be saved.

Step 620 monitors whether the occupant wears a target seat belt 10 that is associated with the target seat 300. If it is detected that the occupant does not wear the target seat belt 10 matched with the target seat 300, step 630 is executed, otherwise, the process ends. Illustratively, the control module 40 may determine whether the occupant seated in the seat 300 is wearing the target seat belt 10 based on the load detection signal output from the seating sensor 50 and the latch state detection signal output from the latch sensor 60. Of course, the control module 40 may determine whether the occupant seated in the seat 300 wears the target seatbelt 10 based on the image information acquired by the occupant monitoring module 70.

In step 630, body posture information of a target occupant collected by the occupant monitoring module 70 is acquired, wherein the target occupant is an occupant seated on the target seat 300 and not wearing the target seat belt 10 matched with the target seat 300.

Step 640, controlling the webbing 11 of the target seat belt 10 to move according to the body posture information so as to adjust the tongue 12 of the target seat belt 10 to a target height through the webbing 11 of the target seat belt 10. In the present embodiment, the height of an object may be understood as the vertical height relative to the floor of the vehicle 1, although other components may be used as references to the system.

In one embodiment, the target height comprises a first target height. Referring to fig. 4, fig. 4 is a first refinement flowchart of step 640 in fig. 3. The controlling the webbing 11 of the target seat belt 10 to move according to the body posture information to adjust the tongue 12 of the target seat belt 10 to a target height through the webbing 11 of the target seat belt 10 specifically includes:

step 641, judging whether the target passenger currently maintains a preset sitting posture according to the body posture information of the target passenger. If it is determined that the target occupant currently maintains the preset sitting posture, step 642 is performed, otherwise, step 630 is returned to, and body posture information of the target occupant is continuously collected.

After the target occupant sits on the target seat 300, various postures may be made, such as sitting, turning, tilting, turning, bending, rising, and the like. Accordingly, the control module 40, upon receiving the body posture information, analyzes the received body posture information to determine which body posture the target occupant is currently in. The preset sitting posture includes a sitting posture and a sitting posture in which the body is slightly inclined to the left or right, and the preset sitting posture may be determined according to the target occupant being seated in the target seat 300 and the inclination angle of the trunk of the body being within a preset angle range (for example, 10 degrees), for example. In this embodiment, the frequency of the occupant monitoring module 70 collecting the body posture information of the target occupant in step 630 may be collected in real time, or may be collected at a preset time interval (for example, 10 ms), that is, the control module 40 receives the current body posture information of the target occupant in real time or at a preset time interval, and analyzes and determines the current body posture information.

Step 642, determining the current height of the preset portion of the body of the target occupant according to the body posture information, and controlling the webbing 11 of the target seat belt 10 to move until the tongue plate 12 of the target seat belt 10 is adjusted to the first target height, wherein the first target height is the same as the current height of the preset portion of the body of the target occupant. It has been found that most occupants are accustomed to pulling the tongue 12 from the same position as their shoulder height while wearing the harness 10, and therefore the predetermined location is preferably the shoulder of the target occupant. Of course, in other embodiments, the adjustment may be performed according to the habit of the occupant, for example, the preset portion may also be the neck of the target occupant. Illustratively, the tongue 12 of the target seat belt 10 may be adjusted to the first target height by: the initial height of the tongue plate 12 is obtained through the image information collected by the occupant monitoring module 70, a height difference between the initial height and the first target height is calculated, the number of turns of the spool of the retractor 20 required to rotate is calculated according to the height difference, and the motor 30 is controlled to drive the retractor 20 to rotate according to the number of turns, so that the tongue plate 12 of the target safety belt 10 is adjusted to the first target height. In the embodiment of the present application, the heights of the two objects are the same, which is understood to mean that the difference in height between the two objects is within a preset difference range (for example, 1 cm).

It will be appreciated that when it is determined that the target occupant is currently in the preset sitting position, the control module 40 controls the webbing 11 of the target seat belt 10 to move according to the preset sitting position, and adjusts the height of the tongue 12 of the target seat belt 10 to be the same as the height of the shoulder of the target occupant in the preset sitting position, so that the occupant can grasp the tongue 12 near the position of the shoulder when maintaining the preset sitting position, without turning around to grasp, and the wearing is convenient.

In another embodiment, the target height comprises a second target height. Referring to fig. 5, fig. 5 is a second refinement flowchart of step 640 in fig. 3. The controlling the webbing 11 of the target seat belt 10 to move according to the body posture information to adjust the tongue 12 of the target seat belt 10 to a target height through the webbing 11 of the target seat belt 10 specifically includes:

in step 643, it is determined whether the target occupant grips the target seat belt 10 according to the body posture information of the target occupant. If it is determined that the target occupant is grabbing the target seat belt 10, the flow is ended, otherwise, step 644 is performed.

Step 644, judging whether the target passenger has an action trend of grabbing the target safety belt 10 according to the body posture information of the target passenger acquired in the preset time. If it is determined that the target occupant has a trend of capturing the target seat belt 10, step 645 is executed, otherwise, step 630 is returned. As described above, the frequency of the occupant monitoring module 70 collecting the body posture information of the target occupant in step 630 may be collected in real time, or may be collected at preset time intervals (e.g. 10 ms), so the control module 40 may analyze and determine the motion trend of the target occupant according to a plurality of continuous body posture information collected during a certain period of time, for example, the control module 40 may determine whether the target occupant has the motion trend of grabbing the target seat belt 10 according to a plurality of continuous postures of the hand of the target occupant during a preset time (e.g. 30 ms) to the current period of time.

Step 645, determining the current height of the hand of the target occupant grasping the target seat belt 10 according to the body posture information, and controlling the webbing 11 of the target seat belt 10 to move until the tongue plate 12 of the target seat belt 10 is adjusted to the second target height, wherein the second target height is the same as the current height of the hand of the target occupant grasping the target seat belt 10, and returning to step 630 after step 645 is performed.

It will be appreciated that when it is determined that the target occupant has a tendency to grasp the target seat belt 10, the control module 40 controls the webbing 11 of the target seat belt 10 to move in real time and quickly according to the current height of the hand of the target occupant grasping the target seat belt 10, so that the height of the tongue plate 12 is kept dynamically synchronized with the current height of the hand of the target occupant grasping the target seat belt 10 until the target occupant grasps the tongue plate 12, and thus the occupant can grasp the tongue plate 12 with his/her hand without turning around, which is convenient to wear.

In yet another embodiment, the target height comprises a first target height and a second target height. Referring to fig. 6, fig. 6 is a third refinement flowchart of step 640 in fig. 3. The controlling the webbing 11 of the target seat belt 10 to move according to the body posture information to adjust the tongue 12 of the target seat belt 10 to a target height through the webbing 11 of the target seat belt 10 specifically includes:

step 646, judging whether the target passenger grabs the target safety belt 10 according to the body posture information of the target passenger, if the target passenger is determined to grab the target safety belt 10, ending the flow, otherwise, executing step 647.

Step 647, determining whether the current height of the preset portion of the body of the target occupant is the same as the height of the tongue plate 12 of the target seat belt 10. If the current height of the preset portion of the body of the target occupant is the same as the height of the tongue 12 of the target seat belt 10, step 650 is executed, otherwise, step 648 is executed.

At step 648, a determination is made as to whether the target occupant is currently maintaining a preset seating position. If it is determined that the target occupant is currently maintaining the preset sitting position, step 649 is performed, otherwise, step 630 is returned.

Step 649, determining the current height of the preset portion of the body of the target occupant according to the body posture information, and controlling the webbing 11 of the target seat belt 10 to move until the tongue plate 12 of the target seat belt 10 is adjusted to the first target height.

Step 650, judging whether the target passenger has an action trend of grabbing the target safety belt 10 according to the body posture information of the target passenger acquired in the preset time, if the target passenger is determined to have an action trend of grabbing the target safety belt 10, executing step 651, otherwise, returning to step 630.

Step 651, determining the current height of the hand of the target occupant grasping the target seat belt 10 according to the body posture information, and controlling the movement of the webbing 11 of the target seat belt 10 until the tongue plate 12 of the target seat belt 10 is adjusted to the second target height, and returning to step 630 after step 651 is performed.

Referring to fig. 7, fig. 7 is a flowchart of another automatic seat belt adjusting method provided in the present application, and the automatic seat belt adjusting method specifically includes the following steps:

and step 660, collecting and storing physical characteristic information of the target passenger, and storing the corresponding height information of the first target height. Wherein the first target height is the same as the current height of the preset part of the body of the target passenger when the target passenger keeps a preset sitting posture.

Step 670 monitors whether the target seat belt 10 is unfastened after the target occupant wears the seat belt. If it is monitored that the target seat belt 10 is unfastened, step 680 is performed, otherwise step 670 is performed again, and monitoring is continued as to whether the target seat belt 10 is unfastened. Illustratively, the control module 40 may determine whether the target seat belt 10 is unfastened based on a latch state detection signal output from the buckle sensor 60. Of course, the control module 40 may also determine whether the target seat belt 10 is unfastened based on the image information acquired by the occupant monitoring module 70.

And 680, controlling the movement of the webbing 11 of the target safety belt 10 according to the first target height corresponding height information until the tongue plate 12 of the target safety belt 11 is adjusted to the first target height.

In step 690, body posture information of the target occupant collected by the occupant monitoring module is obtained.

Step 710, determining whether the target passenger grabs the target safety belt 10 according to the body posture information of the target passenger, if the target passenger is determined to grab the target safety belt 10, ending the flow, otherwise, executing step 720.

Step 720, judging whether the target passenger has an action trend of grabbing the target safety belt 10 according to the body posture information of the target passenger acquired in the preset time. If it is determined that the target occupant has a trend of capturing the target seat belt 10, step 730 is performed, otherwise, step 690 is returned.

Step 730, determining the current height of the hand of the target occupant grasping the target seat belt 10 according to the body posture information, and controlling the webbing 11 of the target seat belt 10 to move until the tongue plate 12 of the target seat belt 10 is adjusted to the second target height, wherein the second target height is the same as the current height of the hand of the target occupant grasping the target seat belt 10, and returning to step 690 after step 730 is performed.
