Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a seat control method, as well as electrical equipment and vehicles. Background Technology

[0002] Some vehicles have a steering wheel hiding mode, in which the steering wheel can be folded down and hidden, providing more interior space. However, hiding the steering wheel requires first folding it down and then folding it into its hidden position. During the folding process, the steering wheel may collide with the driver's legs, potentially causing injury to the driver or preventing the steering wheel from folding down completely and thus failing to hide. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the first objective of the present invention is to provide a seat control method that prevents the steering wheel from hitting the driver or failing to tilt properly during the tilting process, thereby improving the effectiveness of the steering wheel hiding mode and driver safety.

[0004] The second objective of this invention is to provide an electrical device.

[0005] The third objective of this invention is to provide a vehicle.

[0006] To achieve the above objectives, a first aspect of the present invention provides a seat control method, which includes: when the steering wheel of a vehicle performs a downward flipping action in a hidden mode, outputting a driver's seat reversal trigger signal based on the relative distance between the steering wheel and the driver on the driver's seat, so as to move the driver's seat towards the rear seat.

[0007] According to the seat control method of the present invention, when the steering wheel performs a downward movement in the hidden mode, the relative distance between the steering wheel and the driver is considered. When the driver's seat needs to be moved backward, a driver's seat backward movement trigger signal is output. This can avoid collision between the steering wheel and the driver when the steering wheel is downward, so that the driver can avoid the steering wheel in time, ensuring that the steering wheel can be downward in place, improving the effectiveness of the steering wheel downward movement and driver safety.

[0008] In some embodiments, when the relative distance is less than a vertical distance threshold, the seat backward movement trigger signal is output.

[0009] In some embodiments, the relative distance is the relative vertical distance between the bottom of the steering wheel and the driver's leg.

[0010] In some embodiments, the relative vertical distance is the difference between a first vertical distance and a second vertical distance; the first vertical distance is the vertical distance between the bottom of the steering wheel and a reference point inside the vehicle, and the second vertical distance is the vertical distance between the highest point of the driver's legs and the reference point inside the vehicle.

[0011] In some embodiments, the in-vehicle reference point includes the location of an in-vehicle camera.

[0012] In some embodiments, the seat control method further includes: when the relative distance between the driver's seat and the rear passenger is less than a horizontal distance threshold, outputting a driver's seat stop moving control signal so that the driver's seat stops moving towards the rear passenger.

[0013] In some embodiments, the seat control method further includes: when the resistance to the rearward movement of the driver's seat increases or when there is an obstacle behind the driver's seat, outputting a control signal to stop the rearward movement of the driver's seat, so as to stop the driver's seat from moving.

[0014] In some embodiments, the seat control method further includes: when the resistance to the rearward movement of the driver's seat increases or when there is an obstacle behind the driver's seat, outputting a control signal for the driver's seat to move in the opposite direction, so that the driver's seat moves away from the rear seats.

[0015] In some embodiments, the seat control method further includes: when multiple relative distances within a preset time period are all less than a distance threshold, outputting a seat backward movement trigger signal.

[0016] In some embodiments, the seat control method further includes: controlling the driver's seat to stop when the driver's seat moves backward to a target position; and / or, outputting an alarm signal to provide a prompt when the driver's seat stops or moves in the opposite direction.

[0017] To achieve the above objectives, a second aspect of the present invention provides an electrical device comprising a processor and a memory, wherein the memory stores a computer program executable by the processor, and the processor executes the computer program to implement the seat control method described in the above embodiment; or, the electrical device is used to implement the seat control method described above.

[0018] According to the present invention, when the electrical device performs the seat control method described in the above embodiment, it takes into account the relative distance between the steering wheel and the driver when the steering wheel performs the downward movement in the hidden mode. When the driver's seat needs to be moved backward, it outputs a driver's seat backward movement trigger signal, thereby avoiding collision between the steering wheel and the driver when the steering wheel is downward. This allows the driver to avoid the steering wheel in time, ensuring that the steering wheel can be downward in place, improving the effectiveness of the steering wheel downward movement and driver safety.

[0019] To achieve the above objectives, a third aspect of the present invention also provides a vehicle, the vehicle including the aforementioned electrical equipment; or, the vehicle including a steering system, a detection device, and a control device, the steering system having a hidden mode, in which the steering wheel of the steering system is flipped down and moved to a hidden position, and the control device is connected to the detection device to realize the aforementioned seat control method.

[0020] According to the vehicle of the present invention, by employing the electrical equipment of the above embodiment or by executing the seat control method of the above embodiment through the control device, when the steering wheel performs the downward movement in the hidden mode, the relative distance between the steering wheel and the driver is considered, and when the driver's seat needs to be moved backward, a driver's seat backward movement trigger signal is output. This can avoid collision between the steering wheel and the driver when the steering wheel is downward, so that the driver can avoid the steering wheel in time, ensure that the steering wheel can be downward in place, and improve the effectiveness of the steering wheel downward movement and driver safety.

[0021] In some embodiments, the detection device includes: an in-vehicle camera for acquiring in-vehicle image information; a steering wheel position monitoring module for monitoring the steering wheel position; and a human body position monitoring module for monitoring the driver's position.

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] To more clearly describe the seat control method of the present invention, the hidden mode of the steering wheel of the steering system will be explained first.

[0029] For some types of vehicles, the steering wheel is designed with a hidden mode. In hidden mode, the steering wheel is flipped down from its active position and then folded and stored in a hidden position. This saves space inside the car where the steering wheel can be extended, thus providing more spacious space for the user.

[0030] However, since the steering wheel is located above the driver's legs when the driver is sitting in the driver's seat, such as when driving, it is easy for the steering wheel to collide with the driver's legs when it enters the hidden mode and flips down, causing injury to the driver or preventing the steering wheel from flipping down completely.

[0031] To address the aforementioned issues, a first aspect of this invention proposes a seat control method that can prevent the steering wheel from colliding with the driver's legs when it flips down in a hidden mode, thereby improving the effectiveness of the steering wheel hiding mode and driver safety.

[0032] The following is for reference. Figures 1-4 A seat control method according to an embodiment of the present invention is described.

[0033] Figure 1 This is a flowchart of a seat control method according to an embodiment of the present invention, such as... Figure 1 As shown, the seat control method of this invention includes the following steps S1 and S2.

[0034] S1, the vehicle's steering wheel performs a downward flip action in hidden mode.

[0035] Specifically, when the vehicle is in steering wheel hiding mode, the steering wheel flips down from its active state. If a driver is sitting in the driver's seat, the steering wheel may collide with the driver. Therefore, the method in this embodiment of the application also performs step S2.

[0036] S2, based on the relative distance between the steering wheel and the driver on the driver's seat, outputs a driver's seat retraction trigger signal to move the driver's seat towards the rear seats.

[0037] When the vehicle's steering wheel is tilted down in the hidden mode, considering the relative distance between the steering wheel and the driver's seat, if it is determined that the two might interfere with each other, such as in a collision, a driver's seat retraction trigger signal is output. The driver's seat's transmission mechanism then moves the seat backward. Figure 2 As shown in the diagram, moving to the right indicates the rearward direction. Furthermore, if the relative distance between the two components determines that they are unlikely to interfere with or collide, the steering wheel can smoothly flip down and completely hide without causing injury to the driver, thus eliminating the need to trigger the driver's seat to move backward.

[0038] In one embodiment, the seat may be equipped with a transmission mechanism, which is used to move the seat backward to a safe distance from the user by means of motion control commands output by the controller, i.e., a driver's seat backward movement trigger signal.

[0039] According to the seat control method of the present invention, when the steering wheel performs a downward movement in the hidden mode, the relative distance between the steering wheel and the driver is considered. When the driver's seat needs to be moved backward, a driver's seat backward movement trigger signal is output. This can avoid collision between the steering wheel and the driver when the steering wheel is downward, so that the driver can avoid the steering wheel in time, ensuring that the steering wheel can be downward in place, improving the effectiveness of the steering wheel downward movement and driver safety.

[0040] In some embodiments, when the steering wheel is tilted down, the relative distance between the steering wheel and the driver is obtained. If the relative distance is less than the vertical distance threshold, it is considered that the steering wheel may interfere with the driver, such as causing a collision, or hindering the tilting of the steering wheel or causing injury to the driver. At this time, a seat retraction trigger signal is output, and the driver's seat is moved back, thereby avoiding contact between the steering wheel and the driver.

[0041] Conversely, if the relative distance between the steering wheel and the driver is not less than the vertical distance threshold, it is assumed that the steering wheel and the driver will not interfere with each other. In this case, the steering wheel can be flipped down smoothly without causing harm to the driver, and there is no need to trigger the driver's seat to move backward.

[0042] Furthermore, considering that the steering wheel is located above the driver's legs when in use, if the steering wheel is flipped down, the bottom of the steering wheel will contact the driver's legs. Therefore, in some embodiments, the relative distance between the steering wheel and the driver can be the relative vertical distance between the bottom of the steering wheel and the highest point of the driver's legs.

[0043] It should be noted that when in use, the steering wheel is located above the driver's legs, and there is definitely some overlap between the two in the lateral direction. When the steering wheel is tilted down, the bottom of the steering wheel first contacts the highest point of the driver's legs. Therefore, the determination of whether the driver's seat is moved back is based on the relative vertical distance between the bottom of the steering wheel and the highest point of the driver's legs.

[0044] Furthermore, in this embodiment, the relative vertical distance between the bottom of the steering wheel and the highest point of the driver's legs is determined by the relativity of the two with respect to an in-vehicle reference point. For example, this relative distance is the difference between a first vertical distance and a second vertical distance. The first vertical distance is the vertical distance between the bottom of the steering wheel and the in-vehicle reference point, and the second vertical distance is the vertical distance between the highest point of the driver's legs and the in-vehicle reference point.

[0045] For example, the first vertical distance can be obtained through the steering wheel position monitoring module, and the second vertical distance can be obtained through the human body position monitoring module. The monitoring module can use radar monitoring, infrared monitoring, or other usable monitoring methods.

[0046] In some embodiments, the in-vehicle reference point may be a selected fixed point inside the vehicle or other reference points.

[0047] Specifically, in some embodiments, the in-vehicle reference point can be selected from the location of an in-vehicle camera, which is used to collect in-vehicle image information, such as steering wheel image information, driver image information, and rear passenger image information.

[0048] For example, the camera can be fixedly mounted on the roof or in other fixed locations inside the vehicle. The coordinates of the camera's position can be determined in the vehicle's coordinate system. Figure 3 As shown, the camera position coordinates can be (x1, y1), where the vehicle coordinate system can be constructed with the midpoint of the center of the left and right front wheels as the origin.

[0049] One approach is to establish a Cartesian coordinate system with a fixed location inside the vehicle, such as the camera position, as the base point. The vertical distance between the highest point of the user's legs and the base point is monitored. Since the position of the highest point of the user's legs relative to the Cartesian coordinate system is fixed, the vertical distance between the highest point of the driver's legs and the base point can be converted into the coordinates of the seat in the Cartesian coordinate system, for example, (x2, y2).

[0050] Additionally, the vertical distance between the bottom of the steering wheel and the base point is monitored. Since the origin of the steering wheel is fixed relative to the Cartesian coordinate system, the vertical distance monitored by the steering wheel position monitoring module can be converted into the steering wheel's coordinates in the Cartesian coordinate system, for example, (x3, y3). The height difference between the bottom of the steering wheel and the camera base point is h1, and the height difference between the highest point of the user's legs and the camera base point is h2. Therefore, the height difference between the bottom of the steering wheel and the highest point of the user's legs is... h = h1 - h2.

[0051] In some embodiments, the vehicle can be configured with a driver's seat adjustment mode associated with a steering wheel hiding mode. When the steering wheel is tilted down in the hiding mode, it is considered that an activation command for the driver's seat adjustment mode has been received. Alternatively, in another embodiment, a trigger unit can be provided to control the driver's seat adjustment mode. Activation commands for the driver's seat adjustment mode are issued based on user operations on this trigger unit, and correspondingly, the driver's seat adjustment mode can be deactivated based on further user operations on the trigger unit. Both automatic and manual triggering are feasible.

[0052] In some examples, to avoid misjudgment, the relative distance between the steering wheel and the driver can be obtained at preset intervals. When multiple relative distances within a preset time period are less than the vertical distance threshold, a seat retraction trigger signal is output.

[0053] Specifically, the controller activates when the automatic adjustment mode is engaged, and the controller acquires position data at a rate of 1 time per second. The controller identifies the height difference (relative distance) between the steering wheel and the driver's position. When h is less than 5cm, collect data 5 times consecutively. If any one of the 5 collections fails to meet the requirement... If h is less than 10cm, the detection stops; if the controller determines... If h is less than 5cm, the motion control mechanism moves the seat to adjust the user's position and avoid the steering wheel tilting down.

[0054] Furthermore, when controlling the driver's seat to move backward, the relative distance between the driver's seat and the rear passenger can be collected. When the relative distance between the driver's seat and the rear passenger is less than the horizontal distance threshold, a control signal to stop the driver's seat from moving is output so that the driver's seat stops moving towards the rear passenger to avoid a collision with the rear passenger.

[0055] For example, an infrared sensor can be installed behind the driver's seat to detect the position of the seat relative to the rear passengers; if the distance... When s < 10cm, the controller stops the seat from moving backward for adjustment.

[0056] In some embodiments, when controlling the driver's seat to move backward, obstacle monitoring can also be performed behind the driver's seat. When the resistance of the driver's seat moving backward towards the rear seat increases or there is an obstacle behind the driver's seat, where the increased resistance can also be considered as an object being caught in the seat during movement or an obstruction behind the seat, a control signal to stop the driver's seat from moving backward is output so that the driver's seat stops moving and avoids collision between the seat and the obstruction behind it.

[0057] Alternatively, in some examples, when the resistance to the rearward movement of the driver's seat increases or when there is an obstacle behind the driver's seat, a control signal is output to move the driver's seat in the opposite direction, so that the driver's seat moves away from the rear seats, maintaining a certain distance between the seat and the obstacle and avoiding each other.

[0058] For example, an obstacle detection unit can be set up to detect obstacle information behind the driver's seat. If an increase in resistance or an object is detected when the seat moves backward, the driver's seat can be controlled to stop moving backward or move in the opposite direction.

[0059] In some embodiments, when the driver's seat moves backward to the target position, the driver's seat is stopped. At this time, the steering wheel can be smoothly tilted down without interfering with the driver's legs. Conversely, if there is an obstacle behind the driver's seat during its backward movement, the driver's seat is stopped or moved in the opposite direction. Also, when the horizontal relative distance between the driver's seat and the rear passenger is less than a horizontal distance threshold, the driver's seat is stopped from moving backward.

[0060] And / or, when the driver's seat stops or moves in the reverse direction, an alarm signal is output to provide a prompt so that the user can be more directly informed of the specific situation.

[0061] Based on the above explanation, Figure 4 This is a flowchart of a seat control method according to an embodiment of the present invention, such as... Figure 4 As shown, the seat control method includes: S11, the position detection module is activated when the steering wheel is hidden.

[0062] The steering wheel enters a hidden mode, then performs a downward motion, activating the position detection module. The position detection module includes modules for detecting the vertical distance between the steering wheel and the base point, and modules for detecting the vertical distance between the driver's legs and the base point.

[0063] S12 determines the vertical distance difference, i.e., the relative distance, between the steering wheel and the position of the human leg.

[0064] S13, determine whether the relative distance is less than the vertical distance threshold, for example, 5cm. If yes, proceed to step S14; otherwise, return to step S12.

[0065] S14 controls the driver's seat transmission mechanism to move the seat backward.

[0066] S15, determine if there is an obstacle stuck during the seat's backward movement. If yes, proceed to step S16; otherwise, proceed to step S17.

[0067] S16 controls the driver's seat to stop or move in the reverse direction, and issues an alarm.

[0068] S17, control the transmission mechanism to continue moving the seat backward until it reaches the threshold and stops.

[0069] In summary, when the steering wheel is in hidden mode, the system obtains the reference point information at the bottom of the steering wheel. This reference point information refers to the coordinates of the steering wheel in the vehicle coordinate system, which is constructed with the midpoint of the center of the left and right front wheels as the origin. The system also obtains the highest point information of the user's legs at their seat position to determine the user's position. Finally, it determines the relative distance between the steering wheel and the user. Based on this relative distance, if the relative distance exceeds a preset distance, the system adjusts the seat position to move backward so that the user can avoid the steering wheel.

[0070] Based on the seat control method of the above embodiments, a second aspect of the present invention provides an electrical device. In the example, the electrical device can be a control device that executes the seat control method of the above embodiments, such as a domain controller or a seat controller.

[0071] In some embodiments, such as Figure 5 As shown, the electrical device 100 includes a processor 101 and a memory 102. The memory 102 stores a computer program that can be executed by the processor 101. When the processor 101 executes the computer program, it implements the seat control method of the above embodiment.

[0072] Alternatively, in some embodiments, the electrical device 100 is used to implement the seat control method of the above embodiments. For example, the electrical device 100 may include a computer storage medium storing a computer program, which, when executed by a processor, implements the seat control method of the above embodiments.

[0073] Alternatively, in some embodiments, the electrical device 100 may include a computer program product, which includes a computer program stored on a computer-readable storage medium, the computer program including program instructions that, when executed by a computer, cause the computer to perform the seat control method of the above embodiments.

[0074] Based on the above embodiments, a third aspect of the present invention also proposes a vehicle, such as... Figure 6 As shown, vehicle 1 includes electrical equipment 100 as described in the above embodiment.

[0075] Or, such as Figure 7 As shown, vehicle 1 includes a steering system 11, a detection device 12, and a control device 13. The steering system 11 has a hidden mode. In the hidden mode, the steering wheel of the steering system 11 is flipped down and moved to a hidden position. The control device 13 is connected to the detection device 12 to realize the seat control method of the above embodiment.

[0076] like Figure 8 As shown, the detection device 12 includes an in-vehicle camera 121, a steering wheel position monitoring module 122, and a human body position monitoring module 123. The in-vehicle camera 121 is used to collect in-vehicle image information, the steering wheel position monitoring module 122 is used to monitor the steering wheel position, and the human body position monitoring module 123 is used to monitor the driver's position.

[0077] Specifically, when the relative distance between the steering wheel and the driver is less than the vertical distance threshold, the control device 13 controls the seat transmission mechanism to move the seat backward so that the driver's legs avoid the steering wheel and the steering wheel is flipped down into place and then stored in the hidden position.

[0078] like Figure 9As shown, the controller device 13 includes a cockpit domain controller 131 and a seat controller 132. The cockpit domain controller 131 is connected to an in-vehicle camera 121 and a steering wheel position monitoring module 122. The seat controller 132 is connected to the cockpit domain controller 131 and the human body position monitoring module 123.

[0079] Specifically, the cockpit domain controller 131 can acquire steering wheel distance information and in-vehicle camera information for data processing or directly send the acquired information to the seat controller 132. The seat controller 132 controls the seat transmission structure to move the seat backward based on the relative distance between the steering wheel and the driver.

[0080] like Figure 8 As shown in Figure 9, the detection device 12 may further include a distance detection module 124, which is connected to the control device 13 and is used to detect the relative distance between the driver's seat and the rear passenger. Then, when the relative distance between the driver's seat and the rear passenger is less than a horizontal distance threshold, the driver's seat is controlled to stop moving backward.

[0081] In some embodiments, such as Figure 9 As shown, the detection device 12 may further include an obstacle detection module 125, which is connected to the control device 13 and is used to detect the resistance to the driver's seat moving backward or an obstacle behind the driver's seat. Furthermore, when the resistance to the driver's seat moving backward increases or an obstacle exists behind the driver's seat, the driver's seat is controlled to stop moving backward or move in the opposite direction.

[0082] According to the vehicle 1 of the present invention, the relative distance between the steering wheel and the driver is obtained by using the electrical equipment 100 of the above embodiment or by the detection information of the detection device 12. When it is confirmed based on the relative distance that the steering wheel may flip down and make contact or collision with the driver or that the two are very close, the driver's seat is controlled to move backward, thereby preventing the steering wheel system from hitting the driver during the flip-down process.

[0083] Furthermore, obstacle detection can be performed during the driver's seat retraction process. If an obstacle is present, the seat can be stopped from retraction and an alarm can be triggered to notify the user. Additionally, the distance between the seat and the rear passenger can be monitored during the retraction process. If the distance between the two is less than the horizontal distance threshold, the seat can be stopped from retraction to avoid a collision.
