It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0052] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0053] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0054] In order to improve the driving experience of different drivers of the same vehicle, an embodiment of the present application provides an automatic steering wheel adjustment method and a control device. The following is a detailed description of an automatic steering wheel adjustment method and a control device provided in an embodiment of the present application in conjunction with the accompanying drawings.

[0055] Before explaining the automatic steering wheel adjustment method and control device, a steering wheel control system applied to a vehicle and the vehicle are first described in detail.

[0056] Figure 1 A schematic diagram of the structure of a vehicle provided in an embodiment of the present application. The vehicle 200 may at least include: a steering wheel control system 100 .

[0057] The steering wheel control system 100 may be integrated in the vehicle 200 , and the steering wheel control system 100 is used to execute the steps of the automatic steering wheel adjustment method.

[0058] The vehicle 200 may be a commercial vehicle or a household vehicle, without any limitation.

[0059] The vehicle provided in the embodiment of the present application, wherein a steering wheel control system can be integrated in the vehicle, and the steering wheel control system executes the steps of the automatic steering wheel adjustment method to achieve automatic adjustment of the vehicle steering wheel.

[0060] The automatic steering wheel adjustment system provided by the above embodiment of the present application is explained and illustrated in detail with reference to the accompanying drawings as follows: Figure 2 A schematic diagram of a steering wheel control system provided in an embodiment of the present application Figure 1 .like Figure 2 As shown, the steering wheel control system 100 may at least include: a control device 110 and an image acquisition device 120 .

[0061] The image acquisition device 120 is used to acquire images at a position corresponding to the preset driving position of the target vehicle to acquire the facial image of the user in the preset driving position. The image acquisition device 120 is connected to the control device 110 to transmit the acquired facial image of the user in the preset driving position to the control device 110. The control device 110 is used to connect to the control end of the column of the steering wheel of the target vehicle to control the control end of the column of the steering wheel of the target vehicle through the control device 110, thereby realizing automatic adjustment of the steering wheel of the target vehicle. The control device 110 and the control end of the column of the steering wheel of the target vehicle can be connected directly, or the control device 110 can be connected to the vehicle controller, and then the vehicle controller and the control end of the column of the steering wheel of the target vehicle are connected.

[0062] The control device 110 can be used to execute the automatic steering wheel adjustment method. The control device 110 can be selected according to actual conditions. For example, the control device 110 can be a domain controller or a multimedia system. The control device 110 includes but is not limited to parts such as a central control screen. The control device 110 can be used to store facial image information of a cockpit user.

[0063] It should be noted that the domain controller is only used to store the user's facial image information, and the control end of the column is used as the actuator of the steering wheel of the target vehicle to store and retrieve the position information of the steering wheel. The preset telescopic distance or preset pitch angle of the column can be adjusted according to the preset direction through the button next to the column on the vehicle, and the steering wheel position is stored on the column. Among them, whether the position of the steering wheel is adjusted in place depends on whether the user continues the current vehicle ignition cycle and the user's own subjective feelings. Among them, the preset direction can be selected according to the actual situation. The preset telescopic distance can also be selected according to the actual situation. For example, the preset telescopic distance can be set to 22.5mm up and 22.5mm down; then the corresponding preset telescopic stroke of the column is 45±1mm.

[0064] The image acquisition device 120 can be selected according to actual conditions, for example, the image acquisition device 120 can be a vehicle-mounted camera. It should be noted that the position of the image acquisition device 120 in the vehicle can also be selected according to actual conditions, for example, the image acquisition device 120 can be set at the position of the A-pillar of the main cockpit of the vehicle.

[0065] It should be noted that the control device 110 on the same vehicle can store facial image information of at least 5 different drivers, and the control end of the steering column of the corresponding target vehicle also stores state signals of at least 5 different drivers. The state signal of the driver refers to the historical steering wheel information corresponding to at least 5 different drivers.

[0066] Furthermore, Figure 3 A schematic diagram of a steering wheel control system provided in an embodiment of the present application Figure 2 .like Figure 3 As shown, the steering wheel control system 100 may further include: a communication module 130 .

[0067] The control device 110 is connected to the communication module 130; the communication module 130 is used for communication connection with the cloud platform server.

[0068] The communication module 130 may be a wireless communication module or a wired communication module, which is not limited here.

[0069] It should be noted that within the coverage area of ​​the preset factory network cloud platform server, if the user registers in any vehicle within the coverage area of ​​the preset factory network cloud platform server, the user registration information can be transmitted to the control device 110 (such as a domain controller) through the pipe column, and then sent to the cloud platform server by the control device 110 (such as a domain controller) through the communication module 130 to store the user registration information. In this way, within the coverage area of ​​the preset factory network cloud platform server, the user can directly retrieve the historical steering wheel travel information corresponding to the user's stored registration information on different vehicles of the same model, thereby realizing automatic adjustment of the steering wheel and improving user experience.

[0070] The steering wheel control system provided in the embodiment of the present application is composed of a control device, an image acquisition device and a communication module, so as to transmit the facial image of the user in the preset driving position acquired by the image acquisition device to the control device. Due to the connection between the control device and the communication module, the facial image of the user in the preset driving position is uploaded to the cloud platform server through the communication module for storage, so that within the coverage area of ​​the preset factory network cloud platform server, the user can directly retrieve the historical steering wheel travel information corresponding to the registration information stored by the user on different vehicles of the same model, thereby realizing automatic adjustment of the steering wheel and improving the car-using experience and user experience of different drivers of the same vehicle.

[0071] Furthermore, in order to clearly describe the steering wheel control system 100 provided in the above embodiment, the present application also provides a structural schematic diagram of a control device 110. Figure 4 This is a schematic diagram of the structure of a control device provided in an embodiment of the present application. Figure 4 As shown, the control device 110 may include: a processor 111 and a memory 112 .

[0072] The memory 112 stores machine executable instructions that can be executed by the processor 111, that is, when the control device 110 is running, the above machine readable instructions are executed, and the processor 111 communicates with the memory 112 via a bus. The processor 111 can execute the machine executable instructions to implement the automatic steering wheel adjustment method.

[0073] Among them, the memory 112, the processor 111 and the bus components are directly or indirectly electrically connected to each other to realize data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines. The mobile storage device includes at least one software function module that can be stored in the memory 112 in the form of software or firmware or solidified in the operating system (OS) of the electronic device. The processor 111 is used to execute the executable modules stored in the memory 112, such as the software function modules and computer programs included in the steering wheel automatic adjustment method of the mobile storage medium.

[0074] Among them, the memory 112 can be, but is not limited to, random access memory (Random Access Memory, RAM), read-only memory (Read Only Memory, ROM), programmable read-only memory (Programmable Read-Only Memory, PROM), erasable programmable read-only memory (Erasable Programmable Read-Only Memory, EPROM), electrically erasable read-only memory (Electric Erasable Programmable Read-Only Memory, EEPROM), etc.

[0075] The automatic steering wheel adjustment method provided in the embodiment of the present application may be executed by the processor 111 in the control device 110. The automatic steering wheel adjustment method provided in the above embodiment of the present application is explained and illustrated in detail below in conjunction with the accompanying drawings. Figure 5 A schematic diagram of a method for automatically adjusting a steering wheel provided in an embodiment of the present application Figure 1 .like Figure 5 As shown, the method may include:

[0076] S301: If a vehicle ignition signal of a target vehicle is detected, a current facial image of a target user at a preset driving position of the target vehicle is obtained.

[0077] The vehicle ignition signal of the target vehicle may be set according to actual conditions. For example, the vehicle ignition signal may be an ignition gear start signal ig on or an engine start signal engine on.

[0078] In one possible implementation, when the control device detects the vehicle ignition signal of the target vehicle, it means that there is a target user in the preset cockpit of the target vehicle. The target user's face is captured by an image acquisition device (such as a vehicle-mounted camera) set on the A-pillar of the preset cockpit of the target vehicle. After the image acquisition device (such as a vehicle-mounted camera) completes the facial image capture of the target user, a window will pop up on the central control screen to prompt whether to save the captured facial image information of the target user, thereby obtaining the current facial image of the target user in the preset driving seat of the target vehicle.

[0079] S302: Determine whether the target user is a pre-registered user based on the current facial image.

[0080] In one possible implementation, the control device determines whether the user corresponding to the current facial image is a pre-registered user based on the current facial image, and if so, executes step S303; if not, controls the steering wheel of the target vehicle to maintain the current position.

[0081] S303: If the target user is a pre-registered user, obtain pre-stored historical steering wheel travel information of the target user.

[0082] In a possible implementation, if the target user is a pre-registered user, the control device obtains pre-stored historical steering wheel travel information corresponding to the target user.

[0083] The historical steering wheel travel information corresponding to the target user is the optimal steering wheel position information set and saved by the target user and in accordance with his / her driving habits.

[0084] S304. According to the historical steering wheel travel information, the column of the steering wheel is controlled to be adjusted to a position corresponding to the historical steering wheel travel information.

[0085] In one possible implementation, based on the historical steering wheel travel information, the control device can control the steering wheel column of the target vehicle, that is, the historical steering wheel travel information is sent to the control end of the steering wheel column through the CAN communication line, and the control end of the column controls and adjusts the steering wheel to the position corresponding to the historical steering wheel travel information.

[0086] It should be noted that if the target user is a pre-registered user, the column of the target vehicle can be adjusted to any position within 45mm as the optimal position for the target user, but after the target vehicle is turned off, in order to facilitate the target user to get off the vehicle, the column of the target vehicle will automatically return to the 22.5mm position.

[0087] The present application provides a method for automatic steering wheel adjustment. If the control setting detects the vehicle ignition signal of the target vehicle, the current facial image of the target user in the preset driving position of the target vehicle is obtained, and then, based on the current facial image, it is determined whether the target user is a pre-registered user; if the target user is a pre-registered user, the pre-stored historical steering wheel travel information of the target user is obtained, and finally, based on the historical steering wheel travel information, the column of the steering wheel is controlled to be adjusted to the position corresponding to the historical steering wheel travel information, so as to realize automatic adjustment of the steering wheel according to the correspondence between the user's facial image and the historical steering wheel travel information, thereby improving the vehicle experience and user experience of different drivers of the same vehicle. At the same time, after the target user registers and adjusts for the first time, he only needs to perform face recognition when using the vehicle in the later stage, and the steering wheel nine of the target vehicle can be automatically moved to the position when the target user got off the vehicle for the first time, without the need to manually adjust the steering wheel.

[0088] The following is a detailed explanation and description of the automatic steering wheel adjustment method provided in the above embodiment of the present application in conjunction with the accompanying drawings. Figure 6 A schematic diagram of a method for automatically adjusting a steering wheel provided in an embodiment of the present application Figure 2 .like Figure 6 As shown, in the above method, determining whether the target user is a pre-registered user according to the current facial image may include:

[0089] S401: Match the current facial image with a plurality of pre-stored registered facial images.

[0090] S402: If there is a target registered facial image matching the current facial image among the multiple registered facial images, determine that the target user is a pre-registered user.

[0091] In a possible implementation, the control device may perform image matching between the current facial image and a plurality of pre-stored registered facial images to find a registered facial image that is most similar to the current facial image. That is, if there is a target registered facial image that matches the current facial image among the plurality of registered facial images, the target user is determined to be a pre-registered user. If there is no target registered facial image that matches the current facial image among the plurality of registered facial images, the target user is determined to be a pre-unregistered user.

[0092] Optionally, in the above method, obtaining the pre-stored historical steering wheel travel information of the target user may include:

[0093] S403. Determine the historical steering wheel travel information corresponding to the target registered facial image as the historical steering wheel travel information of the target user according to the target registered facial image and the correspondence between the plurality of pre-stored registered facial images and the historical steering wheel travel information.

[0094] In one possible implementation method, the control device first finds the corresponding target registered facial image among multiple pre-stored registered facial images based on the target registered facial image, then obtains the historical steering wheel travel information corresponding to the target registered facial image, and then determines the historical steering wheel travel information corresponding to the target registered facial image as the historical steering wheel travel information of the target user.

[0095] It should be noted that if the target user is a pre-registered user, after the target user adjusts the steering wheel position information, it will be automatically stored after the target vehicle is turned off without any voice prompts or additional pop-up windows. That is, for a registered target user, only the target user's facial image information recognition is needed to call the target user's previous steering wheel position information on the target vehicle.

[0096] The automatic steering wheel adjustment method provided by the present application matches the current facial image with a plurality of pre-stored registered facial images; if there is a target registered facial image matching the current facial image among the plurality of registered facial images, the target user is determined to be a pre-registered user; then, based on the target registered facial image among the plurality of pre-stored registered facial images, the historical steering wheel travel information corresponding to the target registered facial image is obtained, and finally the historical steering wheel travel information corresponding to the target registered facial image is determined as the historical steering wheel travel information of the target user. Thus, the steering wheel of the target vehicle can be automatically adjusted to the historical steering wheel position of the target user according to the historical steering wheel travel information of the target user, thus realizing the automatic adjustment function of the steering wheel of the target vehicle and improving the user experience.

[0097] The following is a detailed explanation and description of the automatic steering wheel adjustment method provided in the above embodiment of the present application in conjunction with the accompanying drawings. Figure 7 A schematic diagram of a method for automatically adjusting a steering wheel provided in an embodiment of the present application Figure 3 .like Figure 7 As shown, in the above method, before determining the historical steering wheel travel information corresponding to the target registered facial image as the historical steering wheel travel information of the target user based on the target registered facial image and the correspondence between the plurality of pre-stored registered facial images and the historical steering wheel travel information, the method may further include:

[0098] S501: If a vehicle start signal of a target vehicle and a registration request of a target user are detected, a registered facial image of the target user in a preset driving position is obtained.

[0099] In one possible implementation, if the control device detects a vehicle start signal of the target vehicle and a registration request of the target user, a registered facial image of the target user in a preset driving position is acquired through an image acquisition device (such as a vehicle-mounted camera).

[0100] Among them, the vehicle start signal of the target vehicle can be a process in which the target vehicle is unlocked and the preset driving position is opened, the target user enters the preset driving position and closes the door, and then the vehicle ignition signal of the target vehicle is detected.

[0101] The registration request of the target user may be that after the image acquisition device (such as a vehicle-mounted camera) completes the facial image acquisition of the target user, a window will pop up on the central control screen to prompt whether to save the acquired facial image information of the target user, thereby obtaining the current facial image of the target user in the preset driving seat of the target vehicle.

[0102] S502: According to a first column adjustment operation of the target user on the steering wheel, the column is adjusted to a first position corresponding to the first column adjustment operation, and historical steering wheel travel information is determined according to the first position of the column.

[0103] S503: Establish and store a correspondence between the target user's registered facial image and historical steering wheel travel information.

[0104] In one possible implementation, the column is first adjusted to a first position corresponding to the first column adjustment operation performed by the target user on the steering wheel. The target user is then stored in a control device, and the first position of the column is determined to be historical steering wheel travel information. Finally, a correspondence between the registered facial image of the target user and the historical steering wheel travel information is established and stored in the control device, and the historical steering wheel travel information is stored in the control end of the column, so that when the target user subsequently uses it, the control end of the column can be directly driven to drive the steering wheel to rotate, and rotate at the corresponding position of the historical steering wheel travel information corresponding to the target user.

[0105] The automatic steering wheel adjustment method provided by the present application, if the control device detects the vehicle start signal of the target vehicle and the registration request of the target user, then obtains the registered facial image of the target user in the preset driving position, and then adjusts the column to the first position corresponding to the first column adjustment operation according to the first column adjustment operation of the target user on the steering wheel, and determines the historical steering wheel travel information according to the first position of the column, and finally establishes and stores the corresponding relationship between the registered facial image of the target user and the historical steering wheel travel information. Therefore, when the target user uses the target vehicle, the steering wheel of the target vehicle can be directly automatically adjusted through the corresponding relationship between the registered facial image of the target user and the historical steering wheel travel information, thereby improving the vehicle use experience and user experience of different drivers of the same vehicle.

[0106] Optionally, in the above method, establishing and storing the correspondence between the registered facial image of the target user and the historical steering wheel travel information may include:

[0107] After a preset time period after receiving the vehicle shutdown signal of the target vehicle, a correspondence between the registered facial image and the historical steering wheel travel information of the target user is established and stored.

[0108] The vehicle shutdown signal can be set according to actual conditions, for example, the vehicle shutdown signal can be an engine off signal. The preset time period can be selected according to actual conditions, for example, the preset time period can be selected as 30S.

[0109] In one possible implementation, after a preset time period (e.g., 30 seconds) after receiving a vehicle shutdown signal (e.g., engine off) from the target vehicle, the column corresponding to the steering wheel will memorize the current steering wheel position of the target user. At this time, the control device will establish a correspondence between the received registered facial image of the target user and the current steering wheel position (i.e., historical steering wheel travel information) and store it.

[0110] It should be noted that after the target vehicle is turned off and locked, it takes about 3 minutes for the target vehicle to go into hibernation.

[0111] The automatic steering wheel adjustment method provided by the present application establishes and stores a correspondence between the registered facial image of the target user and the historical steering wheel travel information after a preset period of time after receiving the vehicle shutdown signal of the target vehicle. Therefore, when the target user uses the target vehicle, the steering wheel of the target vehicle can be directly automatically adjusted based on the correspondence between the registered facial image of the target user and the historical steering wheel travel information, thereby improving the vehicle use experience and user experience of different drivers of the same vehicle.

[0112] Optionally, establishing and storing the correspondence between the target user's registered facial image and historical steering wheel travel information in the above method may include:

[0113] According to the preset target area where the target vehicle is located and the model information of the target vehicle, a correspondence between the registered facial image and the historical steering wheel travel information of the target user is established and stored.

[0114] The preset target area may be selected according to actual conditions. For example, the preset target area may be selected as a closed area such as a preset factory.

[0115] In one possible implementation, the control device establishes and stores a correspondence between the target user's registered facial image and historical steering wheel travel information based on a preset target area (such as a preset factory) where the target vehicle is located and the model information of the target vehicle.

[0116] For example, the target vehicle exchanges information with the cloud platform server of the preset factory through the network. When one of the target vehicles in the model information performs facial image recognition and registration of the target user and sends it to the cloud platform server of the preset factory, other target vehicles corresponding to the model information can directly retrieve the facial image information of the registered target user from the cloud platform server of the preset factory through the network. Then, through the correspondence between the registered facial image of the target user and the historical steering wheel travel information, any one of the target vehicles corresponding to the model information can be operated, that is, after starting the target vehicle, facing the camera, and the column is executed according to the steering wheel position information (historical steering wheel travel information) previously stored by the target user, and the steering wheel column is controlled to be adjusted to the position corresponding to the historical steering wheel travel information, thereby realizing automatic adjustment of the steering wheel.

[0117] The automatic steering wheel adjustment method provided by the present application establishes and stores the correspondence between the registered facial image of the target user and the historical steering wheel travel information according to the preset target area where the target vehicle is located and the model information of the target vehicle. Therefore, when the target user uses the target vehicle with the same model information, the column of the target vehicle can control the column of the steering wheel to adjust to the position corresponding to the historical steering wheel travel information, thereby realizing automatic adjustment of the steering wheel.

[0118] The following is a detailed explanation and description of the automatic steering wheel adjustment method provided in the above embodiment of the present application in conjunction with the accompanying drawings. Figure 8 A schematic diagram of a method for automatically adjusting a steering wheel provided in an embodiment of the present application Figure 4 .like Figure 8 As shown, the above method may also include:

[0119] S601. According to a second column adjustment operation of a target user on a steering wheel, readjust the column to a second position corresponding to the second column adjustment operation.

[0120] S602: Update historical steering wheel travel information according to the second position of the column.

[0121] In a possible implementation, according to the target user's second column adjustment operation on the steering wheel, the column is readjusted to the second position corresponding to the second column adjustment operation. Then, the column position corresponding to the target user stored in the control device is updated, that is, according to the second position of the column, the historical steering wheel travel information is updated, and then the corresponding relationship between the registered facial image of the target user and the historical steering wheel travel information is established and stored in the control device, and the historical steering wheel travel information is stored in the control end of the column, so that when the target user uses it later, the control end of the column can be directly driven to drive the rotation of the steering wheel, and rotate at the corresponding position of the historical steering wheel travel information corresponding to the target user.

[0122] The automatic steering wheel adjustment method provided by the present application readjusts the column to the second position corresponding to the second column adjustment operation according to the target user's second column adjustment operation on the steering wheel; and updates the historical steering wheel travel information according to the second position of the column. Thus, the target user can adjust the position of the steering wheel according to his or her personal habits at any time, and re-establish the corresponding relationship between the target user and the historical steering wheel travel information, so that when the target user uses the target vehicle, the steering wheel can automatically control the steering wheel column to adjust to the position corresponding to the historical steering wheel travel information according to the stored corresponding relationship between the target user and the historical steering wheel travel information, thereby realizing automatic adjustment of the steering wheel.

[0123] Optionally, the above method may further include:

[0124] If the target user is an unregistered user, the column is adjusted to a third position corresponding to the third column adjustment operation according to the target user's third column adjustment operation on the steering wheel.

[0125] In one possible implementation, if the control device determines that the target user is an unregistered user based on the current facial image, the steering wheel of the target vehicle remains in its current position, and then the target user adjusts the third column of the steering wheel according to his or her own needs to adjust the column to a third position corresponding to the third column adjustment operation.

[0126] It should be noted that if the target user needs to save the third position corresponding to the third column adjustment operation, the corresponding relationship between the registered facial image of the target user and the third position corresponding to the third column adjustment operation (i.e., historical steering wheel travel information) can be stored, so that when the target vehicle is used next time, the target vehicle can realize automatic adjustment of the steering wheel when the facial image of the target user is recognized. Of course, the corresponding relationship between the registered facial image of the target user and the third position corresponding to the third column adjustment operation (i.e., historical steering wheel travel information) may not be stored, which depends on the needs of the target user himself.

[0127] The automatic steering wheel adjustment method provided by the present application, if the target user is an unregistered user, then according to the target user's third-column adjustment operation on the steering wheel, the column is adjusted to a third position corresponding to the third-column adjustment operation, so as to subsequently establish a correspondence between the target user's registered facial image and the third position corresponding to the third-column adjustment operation (i.e., historical steering wheel travel information), so that the next time the target vehicle is used, the target vehicle can realize automatic adjustment of the steering wheel when the facial image of the target user is recognized, thereby improving the car-using experience and user experience of different drivers of the same vehicle.

[0128] Optionally, the above method may further include:

[0129] If a vehicle shutdown signal of the target vehicle is received, the control column is adjusted to a position corresponding to the preset shortest steering wheel travel information.

[0130] Among them, the position corresponding to the preset shortest steering wheel travel information can be selected according to actual conditions. For example, the position corresponding to the preset shortest steering wheel travel information can be selected as 22.5 mm.

[0131] In one possible implementation, if the control device receives a vehicle shutdown signal (such as engine off) from the target vehicle, it can control the column to adjust to a position corresponding to a preset shortest steering wheel travel information (such as 22.5 mm) to reserve more space for the target user to get on and off the vehicle.

[0132] The automatic steering wheel adjustment method provided by the present application, if a vehicle shutdown signal of the target vehicle is received, the control column is adjusted to a position corresponding to the preset shortest steering wheel travel information to reserve more space for the target user to get on and off the vehicle.

[0133] Optionally, the above method may further include:

[0134] If a vehicle shutdown signal of the target vehicle is received, the display module on the steering wheel is controlled to display the preset guest sending function display information.

[0135] In one possible implementation, if the control device receives a vehicle shutdown signal (such as engine off) from the target vehicle, it controls the display module on the steering wheel to display preset guest delivery function display information so that the steering wheel moves to the guest delivery position so that the target user has enough space to leave.

[0136] The automatic steering wheel adjustment method provided in the present application controls the display module on the steering wheel to display preset guest-sending function display information if a vehicle shutdown signal of the target vehicle is received, so that the steering wheel can be moved to the guest-sending position so that the target user has enough space to leave.

[0137] To facilitate understanding of the above-mentioned automatic steering wheel adjustment method, the embodiment of the present application further provides an example of a process of the automatic steering wheel adjustment method, which is described below in conjunction with the accompanying drawings. Fig. 9 A schematic diagram of a method for automatically adjusting a steering wheel provided in an embodiment of the present application Figure 5 .like Fig. 9 As shown, the automatic steering wheel adjustment method may include:

[0138] S701: If a vehicle ignition signal of a target vehicle is detected, a current facial image of a target user at a preset driving position of the target vehicle is recognized.

[0139] Specifically, the target vehicle is unlocked, the main driving door of the target vehicle is opened, the target user enters the main driving door and closes the door. After the control device on the target vehicle detects the vehicle ignition signal such as the ignition gear start signal ig on or the engine start signal engine on, the target user is registering facial image information with the image acquisition device (such as a vehicle-mounted camera), and can adjust the steering wheel to the corresponding position according to his own requirements after about 10 seconds. Then the engine is turned off, and within 30 seconds after the engine shutdown signal engineoff is detected, the column connected to the steering wheel will memorize the current steering wheel position of the target user. At this time, the target vehicle is in the stage of turning off and locking the vehicle. This process can last for about 3 minutes. The target vehicle is unlocked again, the main driving door of the target vehicle is opened, and the next target user enters the main driving door and closes the door. After detecting the vehicle ignition signal such as the ignition gear start signal ig on or the engine start signal engine on, the target user is recognizing facial image information with the image acquisition device (such as a vehicle-mounted camera).

[0140] S702: If the target user is a user who has not been registered in advance, the column controlling the steering wheel remains at the current position.

[0141] Specifically, if the target user is a user who has not been registered in advance, the column controlling the steering wheel maintains the current position, and the target user can adjust the position of the steering wheel according to his or her own needs.

[0142] It should be noted that if the target user is a pre-registered user, the user can choose whether to register the facial image information. If necessary, the above step S701 can be referred to; if not, step S702 can be directly executed.

[0143] S703: If the target user is a pre-registered user, the column controlling the steering wheel is adjusted to a position corresponding to the historical steering wheel travel information.

[0144] Specifically, if the target user is a pre-registered user, then after 10 seconds, the control device controls the steering wheel column to be adjusted to a position corresponding to the historical steering wheel travel information, that is, the position before the target user last turned off the engine.

[0145] S704: When the target vehicle is turned off, the control column is adjusted to a position corresponding to the preset shortest steering wheel travel information.

[0146] Specifically, after the control device receives the vehicle shutdown signal (such as engine off) of the target vehicle, it can control the column to adjust to the position corresponding to the preset shortest steering wheel travel information (such as 22.5mm), and the display module on the steering wheel also displays the preset guest delivery function display information to reserve more space for the target user to get on and off the vehicle.

[0147] S705: Establish and store a correspondence between the target user's registered facial image and historical steering wheel travel information according to the preset target area where the target vehicle is located and the model information of the target vehicle.

[0148] Specifically, the target vehicle exchanges information with the cloud platform server of the preset factory through the networking. When one of the target vehicles in the model information performs facial image recognition and registration of the target user and sends it to the cloud platform server of the preset factory, other target vehicles corresponding to the model information can directly retrieve the facial image information of the registered target user from the cloud platform server of the preset factory through the networking. Then, through the correspondence between the registered facial image of the target user and the historical steering wheel travel information, any one of the target vehicles corresponding to the model information is operated, that is, after starting the target vehicle, facing the camera, and the column is executed according to the steering wheel position information (historical steering wheel travel information) previously stored by the target user, and the steering wheel column is controlled to be adjusted to the position corresponding to the historical steering wheel travel information, thereby realizing automatic adjustment of the steering wheel.

[0149] The automatic steering wheel adjustment method provided by the present application, if the vehicle ignition signal of the target vehicle is detected, the current facial image of the target user in the preset driving position of the target vehicle is identified; if the target user is a pre-unregistered user, the column for controlling the steering wheel remains at the current position; if the target user is a pre-registered user, the column for controlling the steering wheel is adjusted to the position corresponding to the historical steering wheel travel information; when the target vehicle is turned off, the control column is adjusted to the position corresponding to the preset shortest steering wheel travel information; according to the preset target area where the target vehicle is located, and the model information of the target vehicle, the corresponding relationship between the registered facial image of the target user and the historical steering wheel travel information is established and stored, so as to realize automatic adjustment of the steering wheel according to the corresponding relationship between the facial image of the user and the historical steering wheel travel information, thereby improving the car experience and user experience of different drivers of the same vehicle. At the same time, after the first registration and adjustment, the target user only needs to perform face recognition when using the car in the later stage, and the steering wheel nine of the target vehicle can be automatically moved to the position when the target user got off the car for the first time, without the need to manually adjust the steering wheel.
