[0015] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0016] In the embodiments of the present application, the inventors propose a vehicle seat adjustment method, device, and vehicle. By obtaining the body feature information of the current occupant, the body feature information includes the grip strength data and height data obtained before the current occupant gets on the vehicle, and the torso data and weight data obtained after the current occupant gets on the vehicle. The grip strength data and height data are used to initially identify the identity of the current occupant, and the torso data and weight data are used to secondarily identify the identity of the current occupant. If the body feature information matches the pre-recorded body feature information of the vehicle owner, the vehicle seat is adjusted based on the seat position corresponding to the vehicle owner. If the body feature information does not match the pre-recorded body feature information of the vehicle owner, the vehicle seat is adjusted based on the torso data and weight data. Thus, by collecting the body feature information of the occupant and making a preliminary judgment on the occupant's identity before the occupant gets on the vehicle, the problem of data stacking caused by collecting information only after the occupant gets on the vehicle can be avoided, thereby reducing the risk of the in-vehicle system crashing. By making a secondary determination of the occupant's identity based on the body feature information collected after the occupant gets on the vehicle and adjusting the vehicle seat in a corresponding manner according to the determination result, on the one hand, the accuracy of identity determination can be improved, and on the other hand, the vehicle seat can be adaptively adjusted according to the identity of the occupant, improving the intelligence of vehicle seat adjustment.

[0017] Please refer to Figure 1 , a vehicle seat adjustment method provided in an embodiment of the present application. This vehicle seat adjustment method can be applied to a vehicle and is specifically used to adaptively adjust the seat of the intelligent cockpit according to the identity of the occupant. The method includes:

[0018] Step S110: Obtain the body characteristic information of the current occupant. The body characteristic information includes the grip strength data and height data obtained before the current occupant gets into the vehicle, and the torso data and weight data obtained after the current occupant gets into the vehicle. The grip strength data and height data are used to preliminarily identify the identity of the current occupant, and the torso data and weight data are used to re-identify the identity of the current occupant.

[0019] In the embodiment of the present application, the current occupant can be the driver (i.e., the occupant in the driver's seat) or a non-driver (i.e., the occupant in a non-driver's seat). Correspondingly, the vehicle can store the seat positions of the vehicle owner in the driver's seat and each non-driver's seat, that is, the vehicle can memorize the seat positions adjusted by the vehicle owner, so that when the vehicle owner needs to use the vehicle, the seat can be automatically adjusted to the seat position suitable for the vehicle owner. Specifically, the vehicle can also memorize the position of the vehicle's outside rearview mirror when the vehicle owner is in the driver's seat, so that when the vehicle owner needs to use the vehicle again and is sitting in the driver's seat, the vehicle's outside rearview mirror can be automatically adjusted to the outside rearview mirror position suitable for the vehicle owner.

[0020] In this embodiment, the current occupant can be the vehicle owner or not. It can be understood that other users besides the vehicle owner may use the vehicle, but the seat positions of the vehicle suitable for the vehicle owner may not be applicable to other users. Therefore, in order to achieve adaptive seat position adjustment, the body characteristic information of the current occupant can be obtained, and then the identity of the current occupant can be identified based on the body characteristic information.

[0021] Among them, the body characteristic information of the current occupant can specifically include the grip strength data and height data obtained before the current occupant gets into the vehicle, and the torso data and weight data obtained after the current occupant gets into the vehicle. In this embodiment, the grip strength data and height data can be used to preliminarily identify the identity of the current occupant, while the torso data and weight data can be used to re-identify the identity of the current occupant. By double-identifying the identity of the current occupant, misjudgment can be avoided, so that more accurate seat position adjustment can be achieved according to the identity of the occupant.

[0022] In the process of obtaining the body characteristic information of the current occupant, as an implementation manner, before the current occupant gets into the vehicle, the grip strength data of the current occupant can be obtained through the door handle grip sensor configured outside the vehicle, and the height data of the current occupant can be obtained through the doorframe scanner configured outside the vehicle during the process of the current occupant opening the door; after the current occupant gets into the vehicle, the sitting posture image of the current occupant after sitting can be obtained through the camera configured inside the vehicle, and the torso data of the current occupant can be obtained based on the sitting posture image; and the weight data of the current occupant can be obtained through the seat pressure sensor configured inside the vehicle.

[0023] Among them, before the current occupant approaches the vehicle but has not yet boarded, if functions configured in the vehicle, such as "automatic seat position adjustment according to the identity of the occupant", are in the on state, then the door handle grip force sensor (optionally, the door handle grip force sensor can use an infrared sensor) and the door side scanner can be automatically triggered to enter the working state. At this time, if the distance between the current occupant and the door is less than the specified distance (optionally, the specific value of the specified distance can be not limited, for example, it can be a value such as 10 millimeters), then the door handle grip force sensor can start to sense the grip action of the current occupant and record the magnitude of the grip force, obtaining grip force data, and the door side scanner can scan the height of the current occupant to obtain height data. Optionally, when the memory of the vehicle is sufficient, the obtained grip force data and height data can be stored in the intelligent cockpit information storage system of the vehicle to facilitate subsequent identification of the occupant based on the grip force data and height data.

[0024] After the current occupant gets in the vehicle, a (pinhole) camera configured inside the door can take a sitting posture image of the occupant after sitting down, and then based on the sitting posture image, the torso data of the current occupant can be obtained. Specifically, the (pinhole) camera configured inside the door can transmit the taken sitting posture image to the torso image recognizer. By analyzing the sitting posture image through the torso image recognizer, the heel coordinates, knee coordinates, hip coordinates, palm coordinates, elbow coordinates, abdominal coordinates, shoulder coordinates, jaw coordinates, contact point coordinates between the back of the head and the headrest, and contact point coordinates between the back and the seat back of the current occupant can be obtained; further, based on the above heel coordinates, knee coordinates, hip coordinates, palm coordinates, elbow coordinates, abdominal coordinates, shoulder coordinates, jaw coordinates, contact point coordinates between the back of the head and the headrest, and contact point coordinates between the back and the seat back, the forearm length, upper body length, thigh length, calf length, neck length, and body thickness of the current occupant can be obtained as the torso data of the current occupant. Among them, the calculation principle and specific calculation process of various torso data are not elaborated here. Optionally, the obtained torso data can also be stored in the intelligent cockpit information storage system of the vehicle to facilitate subsequent identification of the occupant based on this.

[0025] When the current occupant is fully seated on the seat and has not moved for a certain period of time, the seat pressure sensor configured inside the vehicle seat can obtain the weight data of the current occupant and store it in the intelligent cockpit information storage system of the vehicle to facilitate subsequent identification of the occupant based on this.

[0026] Optionally, before the current occupant gets in the vehicle, the order of obtaining the grip strength data and the height data may not be limited. It can be obtained sequentially or simultaneously. For example, the grip strength data can be obtained first and then the height data, the height data can be obtained first and then the grip strength data, or the height data can be obtained simultaneously with the grip strength data.

[0027] Step S120: If the body feature information matches the body feature information of the pre-recorded vehicle owner, adjust the vehicle seat based on the seat position corresponding to the vehicle owner.

[0028] In this embodiment, if the difference between the body feature information of the current occupant and the body feature information of the pre-recorded vehicle owner is within a preset range (it can be understood that the same user may have a weight difference due to the amount of clothing worn, a height difference due to the height of the shoes worn, and a change in grip strength and torso data due to weight changes), it can be determined that the body feature information of the current occupant matches the body feature information of the pre-recorded vehicle owner. At this time, it can be considered that the current occupant is the vehicle owner, and thus the vehicle seat can be adjusted based on the seat position corresponding to the vehicle owner.

[0029] Among them, the vehicle's in-vehicle system pre-stores the position data of each part of the seat when the vehicle owner is sitting on the seat. Adjusting the vehicle seat based on the seat position corresponding to the vehicle owner can be understood as: calling the seat position corresponding to the vehicle owner as the seat position of the current occupant. That is, if the current occupant is the vehicle owner, the current seat position of the vehicle can be automatically adjusted to the memorized seat position of the vehicle owner. It should be noted that if the current occupant is sitting in the driver's seat, the vehicle seat can be automatically adjusted to the seat position of the pre-recorded vehicle owner when sitting in the driver's seat; if the current occupant is sitting in a non-driver's seat, the non-driver's seat of the vehicle can be automatically adjusted to the seat position of the pre-recorded vehicle owner when sitting in the non-driver's seat.

[0030] That is to say, as long as the identity of the current occupant indicates that the current occupant is the vehicle owner, regardless of which position the current occupant is sitting in the vehicle, the position of the seat can be automatically adjusted according to the identity of the current occupant, so that the current occupant can enjoy the active intelligent adjustment of the vehicle seat, eliminating the need for manual operation by the user and improving the driving experience and riding experience of the occupant.

[0031] Step S130: If the body feature information does not match the body feature information of the pre-recorded vehicle owner, adjust the vehicle seat based on the torso data and the weight data.

[0032] In this embodiment, if the difference between the body characteristic information of the current occupant and the body characteristic information of the pre-recorded vehicle owner is not within the preset range, it can be determined that the body characteristic information of the current occupant does not match the body characteristic information of the pre-recorded vehicle owner. At this time, it can be considered that the current occupant is not the vehicle owner. In this way, the vehicle seat can be adjusted based on the torso data and weight data of the current occupant.

[0033] Among them, as described above, the torso data of the current occupant can specifically include the forearm length, upper body length, thigh length, calf length, neck length, and body thickness. In the process of adjusting the vehicle seat based on the torso data and weight data of the current occupant, as an implementation manner, the front-back position of the vehicle seat can be adjusted according to the forearm length and thigh length of the current occupant, the up-down height of the vehicle seat can be adjusted according to the upper body length of the current occupant, the leg rest angle of the vehicle seat can be adjusted according to the ratio of the thigh length to the calf length of the current occupant, the headrest height of the vehicle seat can be adjusted according to the neck length of the current occupant, and the seat back inclination angle of the vehicle seat can be adjusted according to the body thickness and weight data of the current occupant.

[0034] By adjusting the vehicle seat position in the above aspects, the vehicle seat can be better adapted to the body characteristic data of the current occupant, improving the comfort and experience of the current occupant.

[0035] Optionally, the intelligent cockpit information storage system in this embodiment can store the body characteristic information of a certain number of occupants, so that when these occupants need to use the vehicle, identity recognition can be quickly performed, and then the vehicle seat can be automatically adjusted to the seat position adapted to the stored body characteristic information. Then, since each occupant may manually adjust the seat position later, which will bring more data and require memory. To avoid a large amount of data occupying too much memory, the body characteristic information of the occupants can be deleted periodically. Exemplarily, this embodiment can delete the information of the occupants whose usage frequency or frequency of using the vehicle is less than the preset threshold (where the frequency corresponds to the frequency threshold, and the frequency corresponds to the frequency threshold, and the specific values can all be not limited), for example, delete the information of the 3 occupants with the lowest vehicle usage frequency (except for the vehicle owner information, that is, if the vehicle owner has a low usage frequency or frequency of using the vehicle, their body characteristic information can not be deleted). Optionally, if the occupants whose information is deleted after a specified duration need to use the vehicle again, they need to re-acquire (or calculate) and store their body characteristic information.

[0036] A vehicle seat adjustment method provided in this embodiment obtains the body characteristic information of the current occupant. The body characteristic information includes grip strength data and height data obtained before the current occupant gets on the vehicle, and torso data and weight data obtained after the current occupant gets on the vehicle. The grip strength data and height data are used to initially identify the identity of the current occupant, and the torso data and weight data are used to secondarily identify the identity of the current occupant. If the body characteristic information matches the pre-recorded body characteristic information of the vehicle owner, the vehicle seat is adjusted based on the seat position corresponding to the vehicle owner. If the body characteristic information does not match the pre-recorded body characteristic information of the vehicle owner, the vehicle seat is adjusted based on the torso data and the weight data. Therefore, by collecting the body characteristic information of the occupant and making a preliminary judgment on the occupant's identity before the occupant gets on the vehicle, the problem of data stacking caused by collecting information only after the occupant gets on the vehicle can be avoided, thereby reducing the risk of the in-vehicle system crashing. By making a secondary determination of the occupant's identity based on the body characteristic information collected after the occupant gets on the vehicle and adjusting the vehicle seat in a corresponding manner according to the determination result, on the one hand, the accuracy of identity determination can be improved, and on the other hand, adaptive adjustment of the vehicle seat according to the occupant's identity can be realized, enhancing the intelligence of vehicle seat adjustment.

[0037] Please refer to Figure 2 , a vehicle seat adjustment method provided in another embodiment of this application. This vehicle seat adjustment method can be applied to a vehicle and is specifically used for adaptively adjusting the seat of the intelligent cockpit according to the identity of the occupant. The method includes:

[0038] Step S210: Obtain the body characteristic information of the current occupant. The body characteristic information includes grip strength data and height data obtained before the current occupant gets on the vehicle, and torso data and weight data obtained after the current occupant gets on the vehicle. The grip strength data and height data are used to initially identify the identity of the current occupant, and the torso data and weight data are used to secondarily identify the identity of the current occupant.

[0039] Among them, the specific implementation of step S210 can refer to the relevant description of step S110 in the foregoing embodiment and will not be elaborated here.

[0040] Step S220: Compare the grip strength data and height data with the grip strength data and height data of the vehicle owner respectively; and compare the torso data and weight data with the torso data and weight data of the vehicle owner respectively.

[0041] In this embodiment, in the case of obtaining the body characteristic information of the current occupant, in order to be able to adjust the vehicle seat more accurately, the identity of the current occupant can be identified first, so as to be able to adjust the vehicle seat targeted and improve the comfort of the occupant.

[0042] As an implementation manner, during the process of identifying the identity of the current occupant, the grip strength data and height data of the current occupant can be respectively compared with the grip strength data and height data of the vehicle owner, and the torso data and weight data of the current occupant can be respectively compared with the torso data and weight data of the vehicle owner.

[0043] Among them, the specific comparison of the grip strength data and height data of the current occupant with the grip strength data and height data of the vehicle owner can include: comparing the grip strength data of the current occupant with the grip strength data of the vehicle owner, and comparing the height data of the current occupant with the height data of the vehicle owner; the specific comparison of the torso data and weight data of the current occupant with the torso data and weight data of the vehicle owner can include: comparing the torso data of the current occupant with the torso data of the vehicle owner, and comparing the weight data of the current occupant with the weight data of the vehicle owner.

[0044] Step S230: If the difference between the grip strength data and the grip strength data of the vehicle owner is less than a preset strength threshold, the difference between the height data and the height data of the vehicle owner is less than a preset height threshold, the difference between the torso data and the torso data of the vehicle owner is less than a preset torso threshold, and the difference between the weight data and the weight data of the vehicle owner is less than a preset weight threshold, it is determined that the physical characteristic information matches the pre-recorded physical characteristic information of the vehicle owner; otherwise, it is determined that the physical characteristic information does not match the pre-recorded physical characteristic information of the vehicle owner.

[0045] As an implementation manner, if the difference between the grip strength data of the current occupant and the grip strength data of the vehicle owner is less than a preset strength threshold, the difference between the height data of the current occupant and the height data of the vehicle owner is less than a preset height threshold, the difference between the torso data of the current occupant and the torso data of the vehicle owner is less than a preset torso threshold, and the difference between the weight data of the current occupant and the weight data of the vehicle owner is less than a preset weight threshold, it can be determined that the physical characteristic information of the current occupant matches the pre-recorded physical characteristic information of the vehicle owner; otherwise, it is determined that the physical characteristic information of the current occupant does not match the pre-recorded physical characteristic information of the vehicle owner, that is, as long as one of them is not satisfied, it can be determined that the current occupant is not the vehicle owner.

[0046] Among them, the specific value of the preset strength threshold can be not limited, the specific value of the preset height threshold can be not limited, the specific value of the preset torso threshold can be not limited, and the specific value of the preset weight threshold can be not limited.

[0047] Optionally, in this embodiment, the grip strength data and height data of the current occupant can be compared with the grip strength data and height data of the vehicle owner respectively. And when the difference between the grip strength data of the current occupant and the grip strength data of the vehicle owner is less than a preset strength threshold, and the difference between the height data of the current occupant and the height data of the vehicle owner is less than a preset height threshold, then the torso data and weight data of the current occupant can be compared with the torso data and weight data of the vehicle owner respectively. Among them, if after comparing the grip strength data and height data of the current occupant with the grip strength data and height data of the vehicle owner respectively, it is found that the difference between the grip strength data of the current occupant and the grip strength data of the vehicle owner is greater than or equal to the preset strength threshold, and / or the difference between the height data of the current occupant and the height data of the vehicle owner is greater than or equal to the preset height threshold, it can be considered that the current occupant is not the vehicle owner. At this time, in order to save computing resources, the step of "comparing the torso data and weight data of the current occupant with the torso data and weight data of the vehicle owner respectively" can be skipped.

[0048] Step S240: If the body feature information matches the pre-recorded body feature information of the vehicle owner, adjust the vehicle seat based on the seat position corresponding to the vehicle owner.

[0049] Among them, the specific implementation of step S240 can refer to the relevant description of step S120 in the foregoing embodiment, and will not be elaborated here.

[0050] Step S250: If the body feature information does not match the pre-recorded body feature information of the vehicle owner, adjust the vehicle seat based on the torso data and weight data.

[0051] Among them, the specific implementation of step S250 can refer to the relevant description of step S130 in the foregoing embodiment, and will not be elaborated here.

[0052] In this embodiment, whether the vehicle seat is adjusted based on the seat position corresponding to the vehicle owner or based on the torso data and weight data of the current occupant, after the seat adjustment is completed, if the user still wants to adjust the seat position, the seat position can still be adjusted continuously, and at this time, it can be adjusted manually.

[0053] In this way, as an implementation method, when the seat adjustment is completed, an adjustment operation on the vehicle seat can be responded to, and the seat position after the adjustment operation is completed can be used as the (final) seat position corresponding to the current occupant. Optionally, if the current occupant is the vehicle owner, the stored and memorized seat position can also be updated to the manually adjusted seat position.

[0054] A vehicle seat adjustment method provided in this embodiment obtains the physical characteristic information of the current occupant. The physical characteristic information includes the grip strength data and height data obtained before the current occupant gets on the vehicle, and the torso data and weight data obtained after the current occupant gets on the vehicle. The grip strength data and height data are used to initially identify the identity of the current occupant, and the torso data and weight data are used to re-identify the identity of the current occupant; compare the grip strength data and height data with the grip strength data and height data of the vehicle owner respectively; and compare the torso data and weight data with the torso data and weight data of the vehicle owner respectively; if the difference between the grip strength data and the grip strength data of the vehicle owner is less than a preset strength threshold, the difference between the height data and the height data of the vehicle owner is less than a preset height threshold, the difference between the torso data and the torso data of the vehicle owner is less than a preset torso threshold, and the difference between the weight data and the weight data of the vehicle owner is less than a preset weight threshold, determine that the physical characteristic information matches the pre-recorded physical characteristic information of the vehicle owner; otherwise, determine that the physical characteristic information does not match the pre-recorded physical characteristic information of the vehicle owner; if the physical characteristic information matches the pre-recorded physical characteristic information of the vehicle owner, adjust the vehicle seat based on the seat position corresponding to the vehicle owner; if the physical characteristic information does not match the pre-recorded physical characteristic information of the vehicle owner, adjust the vehicle seat based on the torso data and the weight data. Thus, by starting to collect the physical characteristic information of the occupant and making a preliminary judgment on the occupant's identity before the occupant gets on the vehicle, the problem of data stacking caused by starting to collect information only after the occupant gets on the vehicle can be avoided, thereby reducing the risk of the in-vehicle system crashing; by making a secondary judgment on the occupant's identity based on the physical characteristic information collected after the occupant gets on the vehicle and adjusting the vehicle seat in a corresponding manner according to the judgment result, on the one hand, the accuracy of identity judgment can be improved, and on the other hand, adaptive adjustment of the vehicle seat according to the occupant's identity can be achieved, improving the intelligence of vehicle seat adjustment.

[0055] At the same time, by manually adjusting the seat after the seat is completed and using the manually adjusted seat position as the final seat position, the flexibility and operability of vehicle seat adjustment are improved, thereby enhancing the user's driving and riding experience.

[0056] Please refer to Figure 3 , a vehicle seat adjustment method provided in another embodiment of the present application. This vehicle seat adjustment method can be applied to a vehicle and is specifically used to adaptively adjust the seat of the intelligent cockpit according to the identity of the occupant. The method includes:

[0057] Step S310: Obtain the physical characteristic information of the current occupant. The physical characteristic information includes the grip strength data and height data obtained before the current occupant gets into the vehicle, as well as the torso data and weight data obtained after the current occupant gets into the vehicle. The grip strength data and height data are used to preliminarily identify the identity of the current occupant, and the torso data and weight data are used to re-identify the identity of the current occupant.

[0058] Among them, the specific implementation of step S310 can refer to the relevant description of step S110 in the foregoing embodiments, and will not be elaborated here.

[0059] Step S320: If the physical characteristic information matches the pre-recorded physical characteristic information of the vehicle owner, call the seat position corresponding to the vehicle owner as the seat position of the occupant.

[0060] Among them, the specific implementation of step S320 can refer to the relevant descriptions of step S120, step S220, and step S230 in the foregoing embodiments, and will not be elaborated here.

[0061] Step S330: If the physical characteristic information does not match the pre-recorded physical characteristic information of the vehicle owner, adjust the front-back position of the vehicle seat according to the forearm length and thigh length, adjust the up-down height of the vehicle seat according to the upper body length, adjust the leg rest angle of the vehicle seat according to the ratio of the thigh length to the calf length, adjust the headrest height of the vehicle seat according to the neck length, and adjust the seat back inclination angle of the vehicle seat according to the body thickness and weight data, and adjust the opening angle of the vehicle exterior mirror based on the upper body length.

[0062] Among them, the specific implementation of step S330 can refer to the relevant descriptions of step S130, step S220, step S230, and step S250 in the foregoing embodiments, and will not be elaborated here.

[0063] In this embodiment, when the position where the current occupant sits is the driver's seat, if the physical characteristic information of the current occupant does not match the pre-recorded physical characteristic information of the vehicle owner, in addition to adjusting the front-back position of the vehicle seat according to the forearm length and thigh length of the current occupant, adjusting the up-down height of the vehicle seat according to the upper body length of the current occupant, adjusting the leg rest angle of the vehicle seat according to the ratio of the thigh length to the calf length of the current occupant, adjusting the headrest height of the vehicle seat according to the neck length of the current occupant, and adjusting the seat back inclination angle of the vehicle seat according to the body thickness and weight data of the current occupant, the opening angle of the vehicle exterior mirror can also be adjusted according to the upper body length of the current occupant.

[0064] Among them, the opening and closing angle of the vehicle's exterior rearview mirror can be adjusted during the process of adjusting the vehicle seat position or after the vehicle seat position adjustment is completed, and no specific limitation is required.

[0065] Step S340: Track the eyes of the current occupant through the camera configured in the exterior rearview mirror to correct the opening and closing angle.

[0066] Optionally, after the vehicle seat position adjustment is completed, it can be considered that the current occupant is in a seat position suitable for their riding comfort. To improve driving safety, the in-vehicle computer can prompt the current occupant to look at the exterior rearview mirrors on both sides of the vehicle, and track the eyes of the current occupant through the (pinhole) cameras configured in the vehicle's exterior rearview mirrors to correct the opening and closing angles of the exterior rearview mirrors on both sides of the vehicle, so that the exterior rearview mirrors on both sides can adapt to the line of sight of the current occupant.

[0067] Optionally, if the center of the pinhole camera or the camera is aligned with the eyes of the current occupant after calibration, it can be considered that the calibration is completed. Thus, by configuring the pinhole camera in the rearview mirror, the position of the rearview mirror can be finely adjusted to improve the driving experience of the occupant in the driver's seat.

[0068] A vehicle seat adjustment method provided in this embodiment obtains the physical characteristic information of the current occupant. The physical characteristic information includes the grip strength data and height data obtained before the current occupant gets on the vehicle, as well as the torso data and weight data obtained after the current occupant gets on the vehicle. The grip strength data and height data are used to preliminarily identify the identity of the current occupant, and the torso data and weight data are used to secondarily identify the identity of the current occupant. If the physical characteristic information matches the pre-recorded physical characteristic information of the vehicle owner, the seat position corresponding to the vehicle owner is called as the seat position of the occupant. If the physical characteristic information does not match the pre-recorded physical characteristic information of the vehicle owner, the front-back position of the vehicle seat is adjusted according to the forearm length and thigh length, the up-down height of the vehicle seat is adjusted according to the upper body length, the leg rest angle of the vehicle seat is adjusted according to the ratio of the thigh length to the calf length, the headrest height of the vehicle seat is adjusted according to the neck length, and the seat back inclination angle of the vehicle seat is adjusted according to the body thickness and weight data, and the opening and closing angle of the vehicle exterior rearview mirror is adjusted based on the upper body length. The current occupant's eyeballs are tracked through a camera configured in the exterior rearview mirror to correct the opening and closing angle. Thus, by starting to collect the physical characteristic information of the occupant and making a preliminary judgment on the occupant's identity before the occupant gets on the vehicle, the problem of data stacking caused by starting to collect information only after the occupant gets on the vehicle can be avoided, and the risk of the in-vehicle system crashing can be reduced. By making a secondary determination of the occupant's identity based on the physical characteristic information collected after the occupant gets on the vehicle and adjusting the vehicle seat in a corresponding manner according to the determination result, on the one hand, the accuracy of identity determination can be improved, and on the other hand, adaptive vehicle seat adjustment according to the occupant's identity can be realized, and the intelligence of vehicle seat adjustment can be improved.

[0069] Meanwhile, through the pinhole camera configured in the rearview mirror, the position of the rearview mirror can be finely adjusted to improve the driving experience of the occupant in the driver's seat.
