Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0031] Please refer to Figure 1 , which is a flow chart of a method for controlling a car seat provided in an embodiment of the present application. This embodiment is applied to Figure 2 The car seat 100 shown includes a seat cushion 11, a seat back 12 and a foot pedal 13. The seat back 12 is located at one side of the seat cushion 11 and can rotate relative to the seat cushion 11. The foot pedal 13 is rotatably connected to the seat back 12.

[0032] The control method of the automobile seat of this embodiment comprises the following steps: Step 101: Obtain a rotation adjustment instruction for adjusting a seat back, wherein the rotation adjustment instruction includes a rotation direction of the seat back relative to a seat cushion.

[0033] In some embodiments, the method for obtaining the rotation adjustment instruction is not specifically limited. For example, a seat adjustment control may be provided on the car seat 100, and after the user operates the seat adjustment control, the car seat 100 obtains the rotation adjustment instruction. For another example, an application for adjusting the car seat 100 may be provided on the vehicle display screen, and the application sends the rotation adjustment instruction to the car seat 100 in response to the user's operation.

[0034] Please refer again Figure 2 The rotation direction of the seat back 12 relative to the seat cushion 11 includes a clockwise rotation direction and a counterclockwise rotation direction.

[0035] Step 102: Determine the movement direction of the foot pedal when the seat back rotates according to the rotation direction.

[0036] Please refer again Figure 2 When the seat back 12 rotates clockwise relative to the seat cushion 11, the foot pedal moves to the left when the seat back rotates, and when the seat back 12 rotates counterclockwise relative to the seat cushion 11, the foot pedal moves to the right when the seat back rotates. Therefore, after the rotation direction of the seat back 12 is obtained, the movement direction of the foot pedal 13 when the seat back 12 rotates can be known.

[0037] Step 103: When a first obstacle is detected in the moving direction, during the process of adjusting the seat back according to the rotation angle adjustment instruction, the foot pedal is controlled to rotate in a direction away from the first obstacle.

[0038] In some embodiments, an in-vehicle environment image may be captured by an in-vehicle camera, and then image analysis may be performed on the in-vehicle environment image to detect whether there is a first obstacle in the moving direction.

[0039] In some embodiments, the car seat 100 further includes a pedal adjustment motor for controlling the rotation of the foot pedal 13 . The car seat 100 controls the rotation direction and rotation angle of the foot pedal 13 by controlling the operation of the pedal adjustment motor.

[0040] It can be understood that how to control the pedal to rotate in the direction away from the first obstacle is described in detail in subsequent embodiments, and in order to avoid repetition, it will not be described again here.

[0041] Compared with the related art, the embodiment of the present application has at least the following advantages: after determining the rotation direction of the seat back when adjusting, the movement direction of the foot pedal when the seat back rotates is obtained according to the rotation direction, so as to detect whether there is a first obstacle in the movement direction of the foot pedal. In the case of detecting the presence of the first obstacle in the movement direction, during the adjustment of the seat back, the foot pedal is controlled to rotate in the direction away from the first obstacle, thereby effectively avoiding the foot pedal from colliding with the obstacle during the adjustment of the seat back. Through the linkage and coordination of the seat back and the foot pedal, the adjustment of the car seat is made more intelligent and reliable, and the user experience is improved.

[0042] Please refer to Figure 3 , Figure 3 This is a flowchart of the steps of an embodiment of the control method of the car seat of the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The control method of the car seat can be applied to the aforementioned car seat, but is not limited thereto, and the embodiment of the present application does not limit this.

[0043] This embodiment is a specific description of the above embodiment, mainly describing how to control the foot pedal to rotate in a direction away from the first obstacle when a distance sensor is provided on the foot pedal and the distance sensor is used to sense the second distance between the foot pedal and the first obstacle. In this way, it can be further ensured that the foot pedal will not hit the obstacle during the adjustment of the seat back, thereby further improving the reliability of the control method of the car seat.

[0044] The specific process of this embodiment is as follows Figure 3 As shown, the following steps are included: Step 201: Obtain a rotation adjustment instruction for adjusting a seat back, wherein the rotation adjustment instruction includes a rotation direction of the seat back relative to a seat cushion.

[0045] Step 202: Determine the movement direction of the foot pedal when the seat back rotates according to the rotation direction.

[0046] Steps 201 to 202 of this embodiment are similar to steps 101 to 102 of the aforementioned embodiment, and are not described again here to avoid repetition.

[0047] Step 203: When a first obstacle is detected in the moving direction, during the process of adjusting the seat back according to the rotation angle adjustment instruction, a second distance sent by the distance sensor is received at intervals of a first preset time.

[0048] In some embodiments, the first preset time length is not specifically limited and can be set according to actual needs. For example, the first preset time length can be set to 0, 0.1S, 1S, etc. When the first preset time length is set to 0, the distance sensor senses the second distance in real time and sends the sensed second distance to the car seat in real time.

[0049] Step 204: When it is detected that the second distance is less than or equal to the first preset threshold, control the foot pedal to rotate in a direction away from the first obstacle.

[0050] In some embodiments, there is no specific limitation on the size of the first preset threshold, and it can be set according to actual needs.

[0051] In some embodiments, the foot pedal is controlled to rotate in a direction away from the first obstacle until the second distance is greater than a second preset threshold, wherein the second preset threshold is greater than the first preset threshold. In this way, it can be ensured that the foot pedal will not collide with the first obstacle during the adjustment of the seat back, further improving the reliability of the control method of the car seat.

[0052] It is worth noting that during the adjustment of the seat back, the second distance between the foot pedal and the first obstacle will become smaller and smaller. The foot pedal is controlled to rotate in the direction away from the first obstacle until the second distance is greater than the second preset threshold, at which time the foot pedal stops rotating. If the adjustment of the seat back is not yet completed, the rotated foot pedal will continue to move in the direction close to the first obstacle during the adjustment of the seat back. This embodiment receives the second distance sent by the distance sensor every first preset time, so that each time the second distance is detected to be less than or equal to the first preset threshold, the foot pedal can be controlled to rotate again, thereby ensuring that the foot pedal will not touch the first obstacle during the entire adjustment process of the seat back.

[0053] Compared with the related art, the embodiment of the present application has at least the following advantages: after determining the rotation direction of the seat back when adjusting, the movement direction of the foot pedal when the seat back rotates is obtained according to the rotation direction, so as to detect whether there is a first obstacle in the movement direction of the foot pedal. In the case of detecting the presence of the first obstacle in the movement direction, during the adjustment of the seat back, the foot pedal is controlled to rotate in the direction away from the first obstacle, thereby effectively avoiding the foot pedal from colliding with the obstacle during the adjustment of the seat back. Through the linkage and coordination of the seat back and the foot pedal, the adjustment of the car seat is made more intelligent and reliable, and the user experience is improved.

[0054] Please refer to Figure 4 , Figure 4This is a flowchart of the steps of an embodiment of the control method of the car seat of the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The control method of the car seat can be applied to the aforementioned car seat, but is not limited thereto, and the embodiment of the present application does not limit this.

[0055] This embodiment is a further improvement of the above-mentioned embodiment, and the main improvement is that: in this embodiment, the distance sensor includes a first sensor and a second sensor, the first sensor is used to sense the second distance, and the second sensor is used to sense the third distance between the foot pedal and the second obstacle, wherein the second obstacle is an obstacle in the rotation direction of the foot pedal. During the process of the foot pedal rotating in the direction away from the first obstacle, if it is detected that the third distance is less than or equal to the first preset threshold, the foot pedal is controlled to stop rotating and the adjustment of the seat back is stopped. In this way, when there are obstacles on both sides of the foot pedal, the foot pedal can be prevented from colliding with the obstacles on either side, thereby further improving the reliability of the control method of the car seat.

[0056] The specific process of this embodiment is as follows Figure 4 As shown, the following steps are included: Step 301: Obtain a rotation adjustment instruction for adjusting a seat back, wherein the rotation adjustment instruction includes a rotation direction of the seat back relative to a seat cushion.

[0057] Step 302: Determine the movement direction of the footrest when the seat back rotates according to the rotation direction.

[0058] Step 303: When a first obstacle is detected in the moving direction, during the process of adjusting the seat back according to the rotation angle adjustment instruction, a second distance sent by the first sensor is received at intervals of a first preset time.

[0059] Step 304: When it is detected that the second distance is less than or equal to the first preset threshold, control the pedal to rotate in a direction away from the first obstacle.

[0060] Steps 301 to 304 of this embodiment are similar to steps 201 to 204 of the above embodiment, and are not described again here to avoid repetition.

[0061] Step 305: In the process of controlling the pedal to rotate in a direction away from the first obstacle, receiving a third distance sent by the second sensor every second preset time period.

[0062] In some embodiments, the second preset time length is not specifically limited and can be set according to actual needs. For example, the second preset time length can be set to 0, 0.1S, 1S, etc. When the second preset time length is set to 0, the second sensor senses the third distance in real time and sends the sensed third distance to the car seat in real time.

[0063] Step 306: When it is detected that the third distance is less than or equal to the first preset threshold, the foot pedal is controlled to stop rotating and the adjustment of the seat back is stopped.

[0064] It is understandable that, in the process of controlling the pedal to rotate in the direction away from the first obstacle, if it is detected that the third distance is less than or equal to the first preset threshold, it indicates that continuing to rotate the pedal may cause the pedal to collide with the second obstacle. If the pedal is not rotated further, the seat back is still in the process of adjustment, which may cause the pedal to collide with the first obstacle. Therefore, in this case, the pedal is controlled to stop rotating and the seat back is stopped from adjusting, which effectively avoids the collision between the pedal and the first obstacle or the second obstacle, further improving the reliability of the control method of the car seat.

[0065] Compared with the related art, the embodiment of the present application has at least the following advantages: after determining the rotation direction of the seat back when adjusting, the movement direction of the foot pedal when the seat back rotates is obtained according to the rotation direction, so as to detect whether there is a first obstacle in the movement direction of the foot pedal. In the case of detecting the presence of the first obstacle in the movement direction, during the adjustment of the seat back, the foot pedal is controlled to rotate in the direction away from the first obstacle, thereby effectively avoiding the foot pedal from colliding with the obstacle during the adjustment of the seat back. Through the linkage and coordination of the seat back and the foot pedal, the adjustment of the car seat is made more intelligent and reliable, and the user experience is improved.

[0066] Please refer to Figure 5 , Figure 5 This is a flowchart of the steps of an embodiment of the control method of the car seat of the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The control method of the car seat can be applied to the aforementioned car seat, but is not limited thereto, and the embodiment of the present application does not limit this.

[0067] This embodiment is a further improvement of the above embodiment, and the main improvement is that: in this embodiment, the first obstacle includes multiple obstacle categories, and the first preset threshold and the second preset threshold are determined according to the obstacle category of the first obstacle. In this way, a more accurate linkage between the pedal and the seat back can be achieved based on different obstacle categories, making the control method of the car seat more intelligent.

[0068] The specific process of this embodiment is as follows Figure 5 As shown, the following steps are included: Step 401: Obtain a rotation adjustment instruction for adjusting a seat back, wherein the rotation adjustment instruction includes a rotation direction of the seat back relative to a seat cushion.

[0069] Step 402: Determine the movement direction of the footrest when the seat back rotates according to the rotation direction.

[0070] Step 403: When a first obstacle is detected in the moving direction, an image of the first obstacle is captured.

[0071] In some embodiments, an in-vehicle camera is installed in the vehicle, and an image of the first obstacle can be captured by the in-vehicle camera.

[0072] Step 404: Determine the obstacle category of the first obstacle according to the image, and determine a sub-first preset threshold and a sub-second preset threshold corresponding to the obstacle category.

[0073] In some embodiments, the first obstacle includes multiple obstacle categories, the first preset threshold includes multiple sub-first preset thresholds, the second preset threshold includes multiple sub-second preset thresholds, and each obstacle category corresponds to a sub-first preset threshold and a sub-second preset threshold.

[0074] Specifically, the first obstacle of this embodiment may include three obstacle categories, namely: Class A: movable obstacles such as human body parts, Class B: fragile and hard objects - obstacles that cannot be squeezed, and Class C: soft objects - obstacles that can be squeezed to a certain extent. The in-car camera sends the captured image to the controller of the car seat, and the controller determines the specific information of the first obstacle such as shape, size, and category by performing image analysis on the image, and then determines the category of the first obstacle based on the above information.

[0075] More specifically, the sub-first preset threshold corresponding to the Class A obstacle is a1, and the sub-second preset threshold is b1; the sub-first preset threshold corresponding to the Class B obstacle is a2, and the sub-second preset threshold is b2; the sub-first preset threshold corresponding to the Class C obstacle is a3, and the sub-second preset threshold is b3; wherein a1 is greater than a2, a2 ​​is greater than a3, b1 is greater than b2, and b2 is greater than b3. Since the Class A obstacle is a movable obstacle, a1 and b1 are set to be larger, so as to further ensure that the footrest will not collide with the Class A obstacle during the adjustment of the seat back.

[0076] Step 405: During the process of adjusting the seat back according to the rotation angle adjustment instruction, a second distance sent by the first sensor is received at intervals of a first preset time.

[0077] Step 406: When it is detected that the second distance is less than or equal to the sub-first preset threshold, control the pedal to rotate in a direction away from the first obstacle until the second distance is greater than the sub-second preset threshold.

[0078] For ease of understanding, the following example takes the first obstacle as an obstacle located on the left side of the pedal and the second obstacle as an obstacle located on the right side of the pedal. Figure 6 How to implement the control of the car seat based on different obstacle categories in this embodiment is specifically described: Please refer to Figure 6 , is a schematic diagram of the structure of the automobile seat 200 provided in an embodiment of the present application. The automobile seat 200 includes a seat cushion 21, a seat back 22 and a foot pedal 23. The seat back 22 is located on one side of the seat cushion 21 and can rotate relative to the seat cushion 21. The foot pedal 23 is rotatably connected to the seat back 22. The automobile seat 200 also includes a first sensor 231 and a second sensor 232 disposed on opposite sides of the foot pedal 23. The first sensor 231 is used to sense the second distance between the foot pedal 23 and the first obstacle, and the second sensor 232 is used to sense the third distance between the foot pedal 23 and the second obstacle.

[0079] 1. Determine the rotation direction of the seat back 22 by receiving the rotation adjustment instruction, Figure 6 The seat back 22 shown rotates in a clockwise direction, so the footrest 23 moves in a leftward direction when the seat back 22 rotates.

[0080] 2. When the in-car camera captures that there is a first obstacle in the moving direction of the foot pedal 23 and the category of the first obstacle is a Class B obstacle, the controller of the car seat 200 detects that the second distance is less than or equal to a2, then the foot pedal 23 is unfolded, that is, the foot pedal 23 rotates counterclockwise so that the second distance is equal to b2; similarly, when the category of the first obstacle is a Class C obstacle, the controller of the car seat 200 detects that the second distance is less than or equal to a3, then the foot pedal 23 is unfolded, that is, the foot pedal 23 rotates counterclockwise so that the second distance is equal to b3.

[0081] 3. When a second obstacle is detected in the rotation direction of the foot pedal 23, the controller of the car seat 200 receives the third distance during the rotation of the foot pedal 23. Taking the second obstacle as a Class B obstacle as an example, when the controller of the car seat 200 detects that the third distance is equal to a2 and the foot pedal 23 still needs to continue to rotate, the controller of the car seat 200 controls the foot pedal 23 to stop rotating and stops adjusting the seat back 22, thereby avoiding the foot pedal 23 from colliding with the first obstacle or the second obstacle.

[0082] 4. When the first obstacle is a Class A obstacle, since the Class A obstacle is movable, the first sensor 231 and the second sensor 232 start sensing at the same time. The principle is the same as step 3 and will not be repeated here.

[0083] Compared with the related art, the embodiment of the present application has at least the following advantages: after determining the rotation direction of the seat back when adjusting, the movement direction of the foot pedal when the seat back rotates is obtained according to the rotation direction, so as to detect whether there is a first obstacle in the movement direction of the foot pedal. In the case of detecting the presence of the first obstacle in the movement direction, during the adjustment of the seat back, the foot pedal is controlled to rotate in the direction away from the first obstacle, thereby effectively avoiding the foot pedal from colliding with the obstacle during the adjustment of the seat back. Through the linkage and coordination of the seat back and the foot pedal, the adjustment of the car seat is made more intelligent and reliable, and the user experience is improved.

[0084] Please refer to Figure 7 , Figure 7 This is a flowchart of the steps of an embodiment of the control method of the car seat of the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The control method of the car seat can be applied to the aforementioned car seat, but is not limited thereto, and the embodiment of the present application does not limit this.

[0085] This embodiment is a specific description of the above embodiment, mainly describing: when the rotation adjustment instruction package includes a target rotation angle of the seat back relative to the seat cushion, another method is to control the foot pedal to rotate in a direction away from the first obstacle. In this way, it can be ensured that the foot pedal will not hit an obstacle during the adjustment of the seat back, thereby further improving the reliability of the control method of the car seat.

[0086] The specific process of this embodiment is as follows Figure 7 As shown, the following steps are included: Step 501: Obtain a rotation adjustment instruction for adjusting a seat back, wherein the rotation adjustment instruction includes a rotation direction of the seat back relative to a seat cushion.

[0087] Step 502: Determine the movement direction of the footrest when the seat back rotates according to the rotation direction.

[0088] Step 503: When a first obstacle is detected in the moving direction, a first distance between the current pedal and the first obstacle is obtained.

[0089] Step 504: Calculate the movement distance of the foot pedal in the movement direction after the seat back adjustment is completed according to the target rotation angle and rotation direction.

[0090] In some embodiments, the moving distance can be calculated in the following manner: obtain a first rotation angle of the seat back relative to the seat cushion and a second rotation angle of the foot pedal relative to the seat back before the seat back is adjusted; based on the first rotation angle and the second rotation angle, obtain first position information of the foot pedal before the seat back is adjusted; based on the first rotation angle and the target rotation angle, calculate a third rotation angle of the seat back relative to the seat cushion after the seat back is adjusted; based on the third rotation angle and the second rotation angle, obtain second position information of the foot pedal after the seat back is adjusted; determine the moving distance based on the first position information and the second position information.

[0091] Step 505: When the difference between the first distance and the moving distance is less than or equal to the preset safety distance, during the process of adjusting the seat back according to the rotation angle adjustment instruction, the foot pedal is controlled to rotate in a direction away from the first obstacle.

[0092] It is worth noting that this embodiment is similar to the aforementioned embodiment and can also obtain the obstacle type of the obstacle, and then determine the size of the preset safety distance and the rotation angle of the foot pedal in the direction away from the first obstacle based on the obstacle type, thereby further ensuring that during the adjustment of the seat back, the foot pedal will not collide with the obstacle, making the control method of the car seat more intelligent and reliable.
