Bracket device, vehicle-mounted control system, control method and vehicle

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 28, 2024, with application number 202410389411.8 and application name “A bracket device, vehicle-mounted control system, control method and vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application is used in the field of vehicle technology, and in particular relates to a bracket device, a vehicle-mounted control system, a control method, and a vehicle. Background Art

[0003] With the development of intelligent vehicles, more and more models are equipped with display screens in the cockpit. Existing in-vehicle display methods are mainly designed for the needs of the driver, and it is difficult to take into account the experience of other passengers in the car. In some models, although it is possible to use a camera to capture the interior of the car and obtain image information of the driver and front passenger seats. Then, based on the image information of the driver and front passenger seats, the face is detected to adjust the direction of the main control display screen. However, the above solution requires the installation of a separate camera in the cockpit, and the direction of the main control display screen can only be adjusted based on the detection information of the driver and front passenger seats, which not only increases the cost but also cannot adjust the rear screen. Therefore, it is necessary to provide a solution to the above problems. Summary of the Invention

[0004] Embodiments of the present application provide a bracket device, a vehicle-mounted control system, a control method, and a vehicle, so as to adjust the screen angle of an electronic device behind a front seatback while reducing costs.

[0005] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions.

[0006] In a first aspect, a bracket device is provided, which is connected to a first seat. The bracket device is also used to house and power electronic equipment and connect the electronic equipment to an onboard control system. The bracket device is capable of adjusting the pitch angle, and the first seat is capable of adjusting its posture. The electronic equipment includes a screen and a camera. The bracket device can receive screen posture adjustment instructions generated by the electronic equipment based on occupant image information captured by the camera. The posture adjustment instructions indicate the pitch angle of the bracket device or the posture of the first seat. The posture adjustment instructions are then transmitted to the onboard control system. Compared to existing systems that install additional cameras on the driver's seat or passenger seat to capture occupant image information, the present invention eliminates the need for separate cameras on the front seats to capture rear-row occupant image information when a passenger is seated in the second seat behind the first seat, thereby reducing costs. Furthermore, the bracket device can both power the electronic equipment and transmit screen posture adjustment instructions generated by the electronic equipment based on occupant image information captured by the camera to the onboard control system, improving ease of use while adjusting the plane angle of the electronic equipment.

[0007] In one possible implementation, when the support device is also height-adjustable, the screen posture adjustment instruction is also used to indicate the height of the support device. In this manner, when the support device is height-adjustable, if the screen posture adjustment instruction generated by the electronic device based on the occupant image information captured by the camera also indicates the height of the support device, the vehicle control system can also adjust the height of the support device, thereby adjusting the height of the screen, to better align the electronic device's screen with the occupant in the second seat behind the first seat.

[0008] In one possible implementation, the bracket device is also capable of adjusting the left and right rotation angle. The aforementioned screen posture adjustment instruction is also used to indicate the left and right rotation angle of the bracket device. In this manner, when the bracket device is capable of adjusting the left and right rotation angle, if the screen posture adjustment instruction generated by the electronic device based on the occupant image information captured by the camera also indicates the left and right rotation angle of the bracket device, the vehicle-mounted control system can also adjust the left and right rotation angle of the bracket device, thereby adjusting the left and right rotation angle of the screen, to better align the screen of the electronic device with the occupant in the second seat behind the first seat.

[0009] In one possible implementation, the posture of the first seat includes: the position of the first seat in the cabin and / or the tilt angle of the first seat backrest. In this manner, if the first seat is adjustable, the screen angle of the electronic device can be adjusted by adjusting the position of the first seat in the cabin and / or the tilt angle of the first seat backrest.

The above-mentioned vehicle-mounted control system can receive a screen posture adjustment instruction sent by the bracket device, and the posture adjustment instruction is used to indicate the pitch angle of the bracket device or the posture of the first seat. Then, the vehicle-mounted control system can also adjust the pitch angle of the bracket device or the posture of the first seat according to the posture adjustment instruction.

[0011] In a possible implementation, the vehicle-mounted control system is used to adjust the pitch angle of the bracket device when someone is sitting in the first seat and someone is also sitting in the second seat behind the first seat.

[0012] In a possible implementation, the vehicle control system is used to adjust the pitch angle of the bracket device or the posture of the first seat when the first seat is unoccupied but the second seat behind the first seat is occupied.

[0013] In a possible implementation, the vehicle-mounted control system is further configured to adjust the pitch angle of the bracket device when the posture of the second seat changes.

[0014] In a possible implementation, when the support device is also capable of adjusting height, the posture adjustment instruction is further used to indicate the height of the support device. The vehicle-mounted control system is further used to adjust the height of the support device according to the posture adjustment instruction.

[0015] In a possible implementation, when the bracket device can also rotate left and right, the posture adjustment instruction is also used to indicate the left and right rotation angles of the bracket device. The vehicle control system is further used to adjust the left and right rotation angles of the bracket device according to the posture adjustment instruction.

[0034] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0035] In the present application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can represent: a, b, c, a and b, a and c, b and c or a, b and c, where a, b and c can be single or multiple. In addition, in the embodiments of the present application, words such as "first" and "second" do not limit the quantity and order.

[0036] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described in this application as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. To be precise, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. The terms "connection", "coupling" and the like involved in the embodiments of this application should be understood in a broad sense. For example, they may refer to a physical direct connection, or they may refer to an indirect connection achieved through an electronic device, such as a connection achieved through a resistor, inductor, capacitor or other electronic device.

[0037] The present application is described in detail below with reference to the accompanying drawings and embodiments:

[0038] With the development of intelligent vehicles, current smart cars are increasingly focusing on the user experience of passengers and drivers. As shown in FIG1 , the cabin 110 of a vehicle 100 typically includes a center console 111, front seats 112, and rear seats 113. A display screen 1111 is typically located on the center console 111 of the cabin 110. To enhance the user experience for both the driver and front passenger, many vehicles 100 include a camera 114 in the cabin 110, located in front of the front seats 112 (including both the driver and front passenger seats), for capturing head image information of the occupants. Furthermore, sensors are also located in the front seats 112 to detect the occupants' presence and posture. The onboard control system (not shown in FIG1 ) in the vehicle 100 can use the occupant image information captured by the camera 114 and the occupant's presence and posture detected by the sensors to control the rotation of the display screen 1111 on the center console 111, aligning it with the driver or front passenger, or to display a split-screen image on the display screen 1111. The above-mentioned vehicle control system can be installed on the center console 111 or elsewhere in the vehicle. This is not specifically limited in the present embodiment. However, the above approach requires the installation of independent cameras on the A-pillars of the vehicle 100 (i.e., the connecting pillars on both sides of the front windshield of the cabin that connect the roof and the left and right front compartments) in locations convenient for obtaining head image information of the driver and front passenger. This increases production costs, as well as the vehicle's production process and wiring difficulties. In addition, the above approach can only be used to adjust the orientation of the display screen on the center console and cannot provide a good experience for passengers in the rear seats behind the driver or front passenger. To improve the riding experience for rear passengers, electronic devices 115 with screens are also installed behind the driver's seat and front passenger seatbacks in mid- to high-end vehicles. This electronic device 115 is typically installed on the headrests of the front seats to allow passengers sitting in the rear seats to play videos, TV, and games. However, the electronic devices 115 currently installed behind the driver's and passenger's seats are typically fixed to the headrests. This requires passengers to maintain their eye level with the headrests during use, requiring them to maintain a fixed posture for extended periods, resulting in a poor user experience. While some electronic devices installed behind the driver's and passenger's seats can be tilted using brackets, this requires passengers to manually adjust the bracket's tilt according to their needs, resulting in a poor user experience.

[0039] In some embodiments, as shown in FIG2 , the vehicle control system 200 includes a body control module (BCM) 210, a front seat adjustment device 220, a rear seat adjustment device 230, and a camera 114. The front seat adjustment device 220 is used to adjust the fore-aft position of the front seat 112 within the cabin and the recline angle of the seatback. The rear seat adjustment device 230 is used to adjust the fore-aft position of the rear seat 113 within the cabin and the recline angle of the seatback. Both the front seat adjustment device 220 and the rear seat adjustment device 230 are in communication with the body control module 210. The body control module 210 can also control the front seat adjustment device 220 to adjust the fore-aft position of the front seat 112 within the cabin and the recline angle of the seatback based on occupant image information captured by the camera 114. In some embodiments, both the front seat adjustment device 220 and the rear seat adjustment device 230 include a drive motor and a microcontroller unit (MCU). Among them, the microcontroller can adjust the front and rear position of the corresponding seat in the cabin and adjust the tilt angle of the seat back by controlling the drive motor.

[0040] To address this issue, as shown in Figure 3, an embodiment of the present application provides a support device 300 for connecting to the first seat. The support device 300 also houses an electronic device 400, provides power to the electronic device 400, and connects the electronic device 400 to the vehicle control system 200. The support device 300 can adjust the pitch angle, allowing the first seat to adjust its posture. The electronic device 400 includes a screen and a camera. The support device 300 may include a support base 310, a controller 320, a first motor 330, a transmission structure 340, and a placement portion 350. The support base 310 is connected to the first seat. The support base 310 can be detachably connected to the first seat, and the structure of the support base 310 is not specifically limited. The controller 320 and first motor 330 can be mounted on the support base 310, with the rotating shaft of the first motor 330 connected to the placement portion 350 via the transmission structure 340. The placement portion 350 can be used to place the electronic device 400, and the placement portion 350 is provided with a connection port 351 for connecting the electronic device 400. The electronic device 400 can be powered through the connection port 351. In addition, the electronic device 400 can also be connected to the vehicle control system for communication through the connection port 351. The connection port 351 can be a universal serial bus (USB) interface. The USB interface can be selected from various commonly used interfaces, such as Type-A interface, Type-C interface, etc., and the embodiment of the present application does not impose specific restrictions on this. Based on this, the bracket device 300 can receive the screen posture adjustment instruction generated by the electronic device 400 based on the occupant image information captured by the camera. The posture adjustment instruction is used to indicate the pitch angle of the bracket device 300 or the posture of the first seat. Then, the bracket device 300 can also send the posture adjustment instruction to the vehicle control system 200. When there are only two rows of seats in the cabin, the first seat can be the driver's seat or the front passenger seat. When there are more than three rows of seats in the cabin, the first seat is a seat in any row of the cabin except the last row of seats at the rear of the cabin, and a bracket device 300 is provided behind the backrest of the first seat.

[0041] Through the above approach, when a passenger is seated in the second seat behind the first seat, the camera of the electronic device 400 can capture image information of the passenger, and the electronic device 400 can generate screen posture adjustment instructions based on this image information. This posture adjustment instruction can be transmitted to the vehicle control system 200 via the bracket device 300, thereby reducing costs. Furthermore, the bracket device 300 can both power the electronic device 400 and transmit the screen posture adjustment instructions generated by the electronic device 400 based on the passenger image information captured by the camera to the vehicle control system, thereby improving ease of use while adjusting the screen angle of the electronic device 400.

[0042] In one example, the transmission structure 340 can be used only to adjust the pitch angle of the placement portion 350. Based on this. The transmission structure 340 may include a first connecting plate 341 and a second connecting plate 342. The first connecting plate 341 and the second connecting plate 342 are parallel to each other. The first end of the first connecting plate 341 and the first end of the second connecting plate 342 are both fixedly connected to the bottom of the placement portion 350. The second end of the first connecting plate 341 and the second end of the second connecting plate 342 can be provided with a connecting hole, which is used to connect to the rotating shaft of the first motor 330.

[0043] In one example, the placement portion 350 may be a clamping structure, which may be a variety of currently widely used mobile phone clamping structures. Of course, the size of the clamping structure may be adaptively adjusted according to the size of the electronic device 500 to be placed. A universal serial bus (USB) interface may be provided on the clamping structure.

[0044] Of course, the above-mentioned bracket device 300 is only an exemplary embodiment given in the embodiment of the present application. The bracket device 300 can also be any bracket device 300 that can adjust the pitch angle of the placement portion under the control of the controller, and the embodiment of the present application does not make specific restrictions on this.

[0045] In some embodiments, the bracket device 300 provided in the embodiment of the present application can also adjust the height. Among them, as shown in Figure 4, based on Figure 3. The above-mentioned bracket device 300 can also include a lifting structure 370. The lifting structure 370 can be specifically used to adjust the height of the placement portion 350, thereby achieving adjustment of the screen height of the electronic device 400. In one example, the first end of the lifting structure 370 can be fixedly connected to the bracket seat 310. The second end of the lifting structure 370 can be connected to the first mounting portion 360. The first mounting portion 360 is used to install the first motor 330, the transmission structure 340 and the placement portion 350, etc. The controller 320 can adjust the height of the lifting structure 370 according to the control instructions issued by the vehicle-mounted control system, thereby achieving adjustment of the screen height.

[0046] In a possible implementation scheme, the above-mentioned lifting structure 370 can be implemented by an electric telescopic rod. The base of the electric telescopic rod (i.e., the first end of the lifting structure) is fixedly connected to the bracket seat 310. The top of the telescopic part of the electric telescopic rod (i.e., the second end of the lifting structure) is connected to the bottom of the first mounting portion 360. Furthermore, in order to enable the electric telescopic rod to adjust the height more stably, a fixing member can be provided between the electric telescopic rod and the bracket seat 310. The function of the fixing member is to fix the electric telescopic rod to ensure that the position of the electric telescopic rod will not shift after the placement portion 350 places the electronic device 400. The specific structure and setting method of the fixing member are not specifically limited.

[0047] In a possible embodiment, the lifting structure 370 may also include a rotating shaft and a second motor arranged along the backrest height direction of the first seat. The rotating shaft may be connected to the rotating shaft of the second motor. The second motor may be controlled by the controller 320. The first mounting portion 360 may be provided with a first through hole with a thread provided inside. The rotating shaft may be provided with a thread matching the through hole, and the rotating shaft may pass through the first through hole. In addition, a second through hole and a third through hole may be provided on the first mounting portion 360 on both sides of the first through hole. At the same time, a first support rod passing through the first through hole and a second support rod passing through the second through hole may be provided on the bracket seat 310. The heights of the first support rod, the rotating shaft, and the second support rod may be the same.

[0048] Based on this, when the second motor rotates, the first mounting portion 360 cannot rotate due to the limiting effect of the first support rod and the second support rod. At this time, the first mounting portion 360 can only move up and down along the rotation axis to adjust the height of the placement portion. Among them, the above-mentioned lifting structures are all relatively commonly used various mechanical structures that can achieve the lifting function through the control of the controller 320, and the embodiments of the present application will not be described in detail here. In addition, in addition to the above-mentioned several lifting structures, the lifting structure in the embodiments of the present application can also use other various commonly used mechanical structures that can achieve the lifting function through the control of the controller 320, and the embodiments of the present application do not impose specific restrictions on this.

[0049] In one possible implementation, as shown in FIG5 , based on FIG4 , the bracket device 300 provided in the embodiment of the present application may further include a rotating structure 390. A second mounting portion 380 may be provided on the rotating structure 390. The second mounting portion 380 is used to mount the lifting structure 370. Specifically, the rotating structure 390 can drive the lifting structure 370 to rotate left and right, that is, to drive the lifting structure 370 to rotate in a plane parallel to the bottom of the cabin. In the above implementation process, the rotating structure 390 may be a variety of mechanical structures that can achieve the above functions through the drive of a motor, and the embodiment of the present application does not impose any specific restrictions on this.

[0050] In one possible embodiment, the bracket device 300 may further include a telescopic structure. This telescopic structure can be positioned anywhere between the bracket base 310 and the placement portion 350. The telescopic structure is used to adjust the distance between the placement portion and the occupant, that is, the telescopic structure can push the placement portion to move parallel to the cabin bottom toward the occupant. In one example, the telescopic structure can also be implemented using an electric telescopic rod, or the telescopic structure can be implemented using a mechanical structure that can achieve the same or similar functions as the electric telescopic rod. This embodiment of the present application does not impose specific limitations on this.

[0051] In one possible embodiment, as shown in FIG6 , the present embodiment further provides the aforementioned bracket device 300. The bracket device 300 may include a bracket base 310, a controller 320, a three-axis motor 610, and a placement portion 350. The bracket base 310 may be connected to the placement portion 350 via the three-axis motor 610. The three-axis motor 610 can simultaneously adjust the pitch angle, height, and left-right rotation angle of the placement portion 350. The controller 320 can adjust at least one of the pitch angle, height, and left-right rotation angle of the placement portion 350 based on control commands sent by the vehicle-mounted control system 200. The three-axis motor 610 may utilize various commonly used three-axis motor structures that can achieve the aforementioned functions, and this embodiment is not specifically limited thereto. Furthermore, a connection port 351 is provided on the placement portion 350 for supplying power to the electronic device 400. Furthermore, the connection port 351 can also be used to connect the electronic device 400 to the vehicle-mounted control system 200 for communication.

[0052] It is understood that the structure of the bracket device 300 described above is merely an example of some embodiments provided for ease of understanding. In practice, the bracket device 300 only needs to provide a connection port 351 and be capable of adjusting any of the pitch angle, height, and left and right rotation angles. The present embodiment does not impose any specific restrictions on the specific structure of the bracket device 300.

[0053] In some embodiments, as shown in FIG7 , the present application also provides an in-vehicle control system 200. The in-vehicle control system 200 includes a body controller 210, a front seat adjustment device 220, a rear seat adjustment device 230, and the aforementioned support device 300. The front seat adjustment device 220 is used to adjust the fore-aft position of the front seat within the cabin and the tilt angle of the seatback. The rear seat adjustment device 230 is used to adjust the fore-aft position of the rear seat within the cabin and the tilt angle of the seatback. The aforementioned electronic device 40, the front seat adjustment device 220, and the rear seat adjustment device 230 are all communicatively connected to the body controller 210. The body controller 210 can also control the front seat adjustment device 220 to adjust the fore-aft position of the front seat within the cabin and the tilt angle of the seatback based on head image information captured by the camera of the electronic device 400. The aforementioned support device 300 can be positioned on the backrest or behind the headrest of the front seat. In some solutions, each seat in the cabin may be provided with a position sensor (eg, a pressure sensor) for detecting whether there is someone sitting in each seat.

[0054] In one possible implementation, the vehicle-mounted control system 200 may receive a screen posture adjustment command from the support device. The control system 200 may then adjust the pitch angle of the support device or the posture of the first seat based on the posture adjustment command. The posture adjustment command may indicate the pitch angle of the support device 300 or the posture of the first seat.

[0055] In a possible implementation, the vehicle-mounted control system 200 can specifically adjust the pitch angle of the bracket device 300 when the first seat is occupied and the second seat behind the first seat is also occupied. In one example, when there are only two rows of seats in the cabin, the first seat can be the driver's seat or the passenger seat in the cabin, and the second seat can be the seat behind the driver's seat or the seat behind the passenger seat. Based on this, when there is someone in the first seat, only the pitch angle of the bracket device 300 can be adjusted to avoid adjusting the posture of the first seat affecting the experience of the occupant in the first seat. In one example, when there are more than three rows of seats in the cabin, the first seat is any row of seats in the cabin except the last row of seats at the rear of the cabin, and the second seat is the seat in the row behind the first seat.

[0056] In one possible implementation, when the first seat is unoccupied but the second seat behind the first seat is occupied, the pitch angle of the support device 300 or the posture of the first seat is adjusted. Therefore, when the first seat is unoccupied but the second seat is occupied, the pitch angle of the support device 300 or the posture of the first seat can be adjusted, or both can be adjusted simultaneously, to facilitate quicker screen adjustment.

[0057] In one possible implementation, when the posture of the second seat changes, the vehicle control system 200 can also adjust the pitch angle of the bracket device 300. When the posture of the second seat changes, the occupant image information also changes, so the pitch angle of the bracket device 300 can be adjusted as needed.

[0058] In a possible embodiment, when the height and / or left-right rotation angle of the bracket device 300 can be adjusted, the vehicle-mounted control system 200 can also adjust the height and / or left-right rotation angle of the bracket device 300 according to the posture adjustment instruction, thereby achieving the adjustment of the height and / or left-right rotation angle of the screen of the electronic device 400.

[0059] In a possible implementation, as shown in FIG8 , the embodiment of the present application further provides a control method, and the execution process of the control method is described as follows.

[0060] S801: When someone sits on a second seat behind a first seat, the electronic device obtains image information of the occupant on the second seat.

[0061] When the second seat is occupied, a occupancy sensor on the first seat can send a corresponding detection signal to a body controller in the vehicle control system. Upon receiving the detection signal, the body controller can send an instruction to the electronic device to activate a camera to capture image information of the occupant in the second seat.

[0062] S802: The electronic device generates a screen posture adjustment instruction based on the passenger image information.

[0063] The posture adjustment instruction may include at least one of the pitch angle, height, and left-right rotation angle of the screen, etc. In specific implementation, the posture adjustment instruction may be adaptively adjusted according to the adjustment method supported by the bracket device.

[0064] In one possible implementation, the vehicle control system may include a built-in software program for an eye position recognition algorithm and a software program for generating posture adjustment instructions. After the electronic device establishes a communication connection with the vehicle control system, the vehicle control system can send these two software programs to the electronic device. The electronic device then uses the camera to identify the occupant's eye position based on the occupant image information captured by the camera and generates posture adjustment instructions for the screen based on this eye position. For example, when the vehicle control system receives in-seat information from the sensor on the second seat, it can send a command to the electronic device instructing it to activate the camera to capture occupant image information. After capturing the occupant image information, the electronic device can use the software program for the eye position recognition algorithm to identify the occupant's eye position. The software then calculates the required pitch angle of the screen based on the vertical distance between the occupant's eye position and the center of the screen, and generates the corresponding posture adjustment instructions based on this pitch angle.

[0065] Furthermore, when the bracket device supports height adjustment, the above-mentioned posture adjustment instruction may also include instruction information corresponding to the height that needs to be adjusted. Among them, when the bracket device needs to adjust the height, the height of the screen can be adjusted according to the vertical distance between the occupant's eye position and the center of the screen. When the screen height is adjusted and the screen still cannot be directly facing the occupant's eyes, the tilt angle of the screen is adjusted. Of course, the above-mentioned adjustment order is only an example given in the embodiment of the present application. The order of adjustment can be adjusted during specific implementation, and the embodiment of the present application does not impose specific restrictions on this.

[0066] Furthermore, when the support device supports adjusting the left and right rotation angles, and the left and right rotation angles need to be adjusted currently, the posture adjustment instruction may also include indication information corresponding to the left and right rotation angles of the screen.

[0067] In one possible implementation, the electronic device can simply capture occupant image information using a camera. This image information is then directly sent to the vehicle control system for processing, which determines the required pitch angle of the screen. Finally, the bracket device is adjusted based on this pitch angle to align the center of the screen with the occupant's eyes.

[0068] Similarly, when the bracket device supports adjusting the height and / or left and right rotation angle, the posture adjustment instruction can also include indication information corresponding to the left and right rotation angle of the screen and / or indication information corresponding to the height, which is not described in detail in the embodiments of the present application.

[0069] S803: The support device receives the posture adjustment instruction and sends the posture adjustment instruction to the vehicle control system.

[0070] The bracket device can be connected to the vehicle control system in a wired or wireless manner. When the bracket device is connected to the vehicle control system in a wireless manner, a wireless communication method such as Bluetooth, Zifeng, Xingshan, or WiFi can be selected, and this embodiment of the application does not impose specific restrictions on this.

[0071] S804: When the second seat behind the first seat is occupied by someone but the first seat is unoccupied, the vehicle-mounted control system adjusts the pitch angle of the bracket device or the posture of the first seat through the vehicle-mounted control system.

[0072] The posture of the first seat may include the position of the first seat in the cabin and / or the tilt angle of the backrest of the first seat. During actual adjustment, the posture of the first seat may be adjusted in a corresponding manner according to actual needs.

[0073] S805: The adjustment is completed, and the adjustment process ends.

[0074] In one possible implementation, after the vehicle-mounted control system controls the bracket device and / or the first seat to complete the adjustment, if the user's eye position does not change within 2 seconds, the adjustment process can be considered complete and the adjustment process can be terminated.

[0075] In one possible implementation, when the first seat is occupied and the second seat behind the first seat is also occupied, the pitch angle of the support device can be adjusted via the vehicle control system. In this case, because the first seat is occupied, adjusting the posture of the first seat would affect the occupant of the first seat, so only the pitch angle of the support device can be adjusted.

[0076] In one possible implementation, considering that a passenger may adjust the posture of the second seat while in the vehicle, causing the passenger's eye position to change, the electronic device can continuously monitor the passenger's eye position during use. Once the change in the passenger's eye position exceeds a set threshold, the pitch angle of the bracket device or the posture of the first seat is readjusted.

[0077] In a possible embodiment, if the bracket device supports adjusting the height and / or left and right rotation angle, when someone is sitting in the first seat and someone is also sitting in the second seat behind the first seat, the vehicle control system can also adjust the height and / or left and right selection angle of the bracket device.

[0078] In one possible implementation, the present application also provides a computer-readable storage medium storing computer program instructions. When the computer program instructions are executed by a processor, the control method in any of the above-mentioned implementations is implemented. The computer-readable storage medium may be a magnetic medium (e.g., a floppy disk, a hard disk, a magnetic tape), an optical medium (e.g., a DVD), or a semiconductor medium (e.g., a solid state drive (SSD)).

[0079] In one possible implementation, the present application also provides a computer program product that, when executed by a processor, implements the control method described in any of the above implementations. The computer program product can be downloaded via an online service, or can be embedded in a memory within a control circuit within a power converter, or stored in a computer-readable storage medium.

Among them, the non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory.
