[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 footrest 13. The seat back 12 is located on one side of the seat cushion 11 and can rotate relative to the seat cushion 11. The footrest 13 is rotatably connected to the seat back 12.

[0032] The control method of the car seat of this embodiment includes the following steps:

[0033] Step 101: obtaining a rotation adjustment instruction for adjusting the seat back, wherein the rotation adjustment instruction comprises a rotation direction of the seat back relative to the seat cushion.

[0034] In some embodiments, the manner of obtaining the rotation adjustment instruction is not specifically limited. For example, a seat adjustment control can be provided on the automobile seat 100, and the automobile seat 100 obtains the rotation adjustment instruction after the user operates the seat adjustment control. For another example, an application for adjusting the automobile seat 100 can be provided on the display screen of the car machine, and the application sends the rotation adjustment instruction to the automobile seat 100 in response to the operation of the user.

[0035] Please refer to Figure 2 , the rotation direction of the seat back 12 relative to the seat cushion 11 comprises a clockwise rotation direction and a counterclockwise rotation direction.

[0036] Step 102: determining the moving direction of the footboard during the rotation of the seat back according to the rotation direction.

[0037] Please refer to Figure 2 , when the seat back 12 rotates clockwise relative to the seat cushion 11, the moving direction of the footboard during the rotation of the seat back is leftward, and when the seat back 12 rotates counterclockwise relative to the seat cushion 11, the moving direction of the footboard during the rotation of the seat back is rightward. Therefore, after obtaining the rotation direction of the seat back 12, the moving direction of the footboard 13 during the rotation of the seat back 12 can be obtained.

[0038] Step 103: in the case that a first obstacle exists in the moving direction, controlling the footboard to rotate away from the first obstacle during the adjustment of the seat back according to the rotation angle adjustment instruction.

[0039] In some embodiments, the in-vehicle camera can be used to capture an in-vehicle environment image, and the in-vehicle environment image can be analyzed to detect whether the first obstacle exists in the moving direction.

[0040] In some embodiments, the automobile seat 100 further comprises a footboard adjustment motor for controlling the rotation of the footboard 13, and the automobile seat 100 controls the rotation direction and the rotation angle of the footboard 13 by controlling the operation of the footboard adjustment motor.

[0041] It can be understood that how to control the footboard to rotate away from the first obstacle is described in detail in subsequent embodiments, and to avoid repetition, it will not be described here.

[0042] Compared with the related art, the embodiment of the application has at least the following advantages: after determining the rotation direction of the seat back adjustment, the moving direction of the footboard during the rotation of the seat back is obtained according to the rotation direction, so as to detect whether there is a first obstacle in the moving direction of the footboard. In the case where it is detected that there is a first obstacle in the moving direction, the footboard is controlled to rotate away from the first obstacle during the adjustment of the seat back, so as to effectively avoid the collision between the footboard and the obstacle during the adjustment of the seat back. Through the linkage of the seat back and the footboard, the adjustment of the automobile seat is more intelligent and reliable, and the use experience of the user is improved.

[0043] Please refer to Figure 3 , Figure 3 is a step flowchart of an embodiment of the control method of the automobile seat. The order of the steps in the flowchart can be changed according to different needs, and some steps can be omitted. The control method of the automobile seat can be applied to the automobile seat described above, but is not limited thereto, and the embodiments of the application do not limit this.

[0044] This embodiment is a specific description of the foregoing embodiments, mainly explaining how to control the footboard to rotate away from the first obstacle in the case where the distance sensor is arranged on the footboard and the distance sensor is used to sense the second distance between the footboard and the first obstacle. In this way, it can be further ensured that the footboard will not collide with the obstacle during the adjustment of the seat back, thereby further improving the reliability of the control method of the automobile seat.

[0045] The specific process of this embodiment is shown in Figure 3 , including the following steps:

[0046] Step 201: Obtain a rotation adjustment instruction for adjusting the seat back, wherein the rotation adjustment instruction includes the rotation direction of the seat back relative to the seat cushion.

[0047] Step 202: Determine the moving direction of the footboard during the rotation of the seat back according to the rotation direction.

[0048] Steps 201 to 202 of this embodiment are similar to steps 101 to 102 of the foregoing embodiments, and will not be described again here to avoid repetition.

[0049] Step 203: In the case where it is detected that there is a first obstacle in the moving direction, during the adjustment of the seat back according to the rotation angle adjustment instruction, the second distance sent by the distance sensor is received every first preset time interval.

[0050] In some embodiments, the size of 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. In the case where 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 automobile seat in real time.

[0051] Step 204: In the case where the second distance is less than or equal to the first preset threshold, the footboard is controlled to rotate away from the first obstacle.

[0052] In some embodiments, the size of the first preset threshold is not specifically limited, and can be set according to actual needs.

[0053] In some embodiments, the footboard is controlled to rotate away from the first obstacle until the second distance is greater than a second preset threshold, where the second preset threshold is greater than the first preset threshold. In this way, it can be ensured that the footboard does not collide with the first obstacle during the adjustment of the seat back, further improving the reliability of the control method of the automobile seat.

[0054] It is worth noting that during the adjustment of the seat back, the second distance between the footboard and the first obstacle will become smaller and smaller. After the footboard is controlled to rotate away from the first obstacle until the second distance is greater than the second preset threshold, the footboard stops rotating. If the adjustment of the seat back is not yet complete, the rotated footboard will continue to move towards the first obstacle during the adjustment of the seat back. In this embodiment, the second distance sent by the distance sensor is received every first preset time length, so that the footboard can be controlled to rotate again every time the second distance is detected to be less than or equal to the first preset threshold, thereby ensuring that the footboard does not touch the first obstacle during the entire adjustment of the seat back.

[0055] Compared with related technologies, the embodiments of the present application have at least the following advantages: after determining the rotation direction of the seat back adjustment, the moving direction of the footboard during the rotation of the seat back is obtained according to the rotation direction, so that it can be detected whether there is a first obstacle in the moving direction of the footboard. In the case where a first obstacle is detected in the moving direction, the footboard is controlled to rotate away from the first obstacle during the adjustment of the seat back, thereby effectively avoiding the collision between the footboard and the obstacle during the adjustment of the seat back. Through the above linkage of the seat back and the footboard, the adjustment of the automobile seat is more intelligent and reliable, and the user's use experience is improved.

[0056] For reference Figure 4 , Figure 4is a step flow chart of an embodiment of the control method of the vehicle seat. The order of the steps in the flow chart can be changed according to different needs, and some steps can be omitted. The control method of the vehicle seat can be applied to the vehicle seat described above, but is not limited thereto, and the embodiments of the present application do not limit the same.

[0057] The embodiment is a further improvement of the foregoing embodiments, and the main improvement is that in the embodiment, the distance sensor includes a first sensor and a second sensor, the first sensor is used to sense a second distance, and the second sensor is used to sense a third distance between the foot pedal and a second obstacle, wherein the second obstacle is an obstacle in the rotating direction of the foot pedal. During the rotation of the foot pedal in the direction away from the first obstacle, if the third distance is less than or equal to a first preset threshold, the rotation of the foot pedal is controlled to stop, and the adjustment of the seat back is also stopped. In this way, in the case that there are obstacles on both sides of the foot pedal, the collision between the foot pedal and any side obstacle can be avoided, thereby further improving the reliability of the control method of the vehicle seat.

[0058] The specific process of the embodiment is shown in Figure 4 , and includes the following steps:

[0059] Step 301: Obtain a rotating adjustment instruction for adjusting the seat back, wherein the rotating adjustment instruction includes a rotating direction of the seat back relative to the seat cushion.

[0060] Step 302: Determine the moving direction of the foot pedal during the rotation of the seat back according to the rotating direction.

[0061] Step 303: In the case that a first obstacle is detected in the moving direction, during the adjustment of the seat back according to the rotating angle adjustment instruction, the second distance sent by the first sensor is received every first preset time interval.

[0062] Step 304: In the case that the second distance is less than or equal to a first preset threshold, the foot pedal is controlled to rotate in the direction away from the first obstacle.

[0063] The steps 301 to 304 of the embodiment are similar to the steps 201 to 204 of the foregoing embodiments, and are not described herein again to avoid repetition.

[0064] Step 305: During the control of the foot pedal to rotate in the direction away from the first obstacle, the third distance sent by the second sensor is received every second preset time interval.

[0065] In some embodiments, the size of 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. In the case where 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 automobile seat in real time.

[0066] Step 306: In the case where the third distance is less than or equal to the first preset threshold, the control of the foot pedal is stopped from rotating, and the adjustment of the seat back is also stopped.

[0067] It can be understood that, in the process of controlling the foot pedal to rotate away from the first obstacle, if the third distance is detected to be less than or equal to the first preset threshold, it indicates that the continued rotation of the foot pedal can cause the foot pedal to collide with the second obstacle. If the foot pedal is not continued to rotate, since the seat back is still in the adjustment process at this time, the foot pedal will collide with the first obstacle. Therefore, in this case, the foot pedal is controlled to stop rotating, and the adjustment of the seat back is also stopped, which effectively avoids the collision of the foot pedal with the first obstacle or the second obstacle, and further improves the reliability of the control method of the automobile seat.

[0068] Compared with the related art, the embodiments of the present application have at least the following advantages: after determining the rotation direction of the seat back during adjustment, the moving direction of the foot pedal during the rotation of the seat back is obtained according to the rotation direction, so as to detect whether there is a first obstacle in the moving direction of the foot pedal. In the case where a first obstacle is detected in the moving direction, the foot pedal is controlled to rotate away from the first obstacle during the adjustment of the seat back, so as to effectively avoid the collision of the foot pedal with the obstacle during the adjustment of the seat back. Through the above linkage of the seat back and the foot pedal, the adjustment of the automobile seat is more intelligent and reliable, and the user's use experience is improved.

[0069] Please refer to Figure 5 , Figure 5 is a step flowchart of an embodiment of the control method of the automobile seat. The order of the steps in the flowchart can be changed, and some steps can be omitted according to different needs. The control method of the automobile seat can be applied to the automobile seat described above, but is not limited thereto, and the embodiments of the present application do not limit this.

[0070] This embodiment is a further improvement of the foregoing embodiments, and the main improvement is that, in this embodiment, the first obstacle includes a plurality of obstacle categories, and the sizes of the first preset threshold and the second preset threshold are also determined according to the obstacle category of the first obstacle. In this way, more accurate linkage of the foot pedal and the seat back can be achieved based on different obstacle categories, so that the control method of the automobile seat is more intelligent.

[0071] The specific process of the embodiment is as shown in Figure 5 and includes the following steps:

[0072] Step 401: Obtain a rotation adjustment instruction for adjusting the seat back, wherein the rotation adjustment instruction includes a rotation direction of the seat back relative to the seat cushion.

[0073] Step 402: Determine the moving direction of the footboard when the seat back rotates according to the rotation direction.

[0074] Step 403: In the case where a first obstacle exists in the moving direction, capture an image of the first obstacle.

[0075] In some embodiments, an in-vehicle camera is installed in the vehicle, and the image of the first obstacle can be captured by the in-vehicle camera.

[0076] 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.

[0077] In some embodiments, the first obstacle includes multiple obstacle categories, the first preset threshold includes multiple sub-first preset thresholds, and the second preset threshold includes multiple sub-second preset thresholds, each obstacle category corresponds to a sub-first preset threshold and a sub-second preset threshold.

[0078] Specifically, the first obstacle of the embodiment can include three obstacle categories, namely: A level: movable obstacles such as human body parts, B level: fragile and hard objects - obstacles that cannot be squeezed, and C level: soft objects - obstacles that can be squeezed. The in-vehicle camera sends the captured image to the controller of the car seat, and the controller determines the specific information of the shape, size, and category of the first obstacle by image analysis on the image, and then determines the category of the first obstacle based on the above information.

[0079] More specifically, the sub-first preset threshold corresponding to the A level obstacle is a1, and the sub-second preset threshold is b1; the sub-first preset threshold corresponding to the B level obstacle is a2, and the sub-second preset threshold is b2; the sub-first preset threshold corresponding to the C level 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 A level obstacle is a movable obstacle, a1 and b1 are set to be larger, thereby further ensuring that the footboard does not collide with the A level obstacle during the adjustment process of the seat back.

[0080] Step 405: During the adjustment of the seat back according to the rotation angle adjustment instruction, the second distance sent by the first sensor is received every first preset time interval.

[0081] Step 406: in the case of detecting that the second distance is less than or equal to the sub first preset threshold, rotating the footrest towards the direction away from the first obstacle until the second distance is greater than the sub second preset threshold.

[0082] For the convenience of understanding, the following takes the first obstacle as the obstacle located on the left side of the footrest and the second obstacle as the obstacle located on the right side of the footrest as an example, and combines the above-mentioned embodiments to illustrate the implementation of the control of the automobile seat based on different obstacle categories. Figure 6 The implementation of the automobile seat based on different obstacle categories is specifically described as follows:

[0083] Please refer to Figure 6 , which is a structural schematic diagram of the automobile seat 200 provided by the embodiment of the present application. The automobile seat 200 comprises a seat cushion 21, a seat back 22 and a footrest 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 footrest 23 is rotatably connected to the seat back 22. The automobile seat 200 further comprises a first sensor 231 and a second sensor 232 arranged on opposite sides of the footrest 23. The first sensor 231 is used to sense the second distance between the footrest 23 and the first obstacle, and the second sensor 232 is used to sense the third distance between the footrest 23 and the second obstacle.

[0084] 1. By receiving the received rotation adjustment instruction, the rotation direction of the seat back 22 is determined, Figure 6 As shown in the figure, the rotation direction of the seat back 22 is clockwise rotation, and then the moving direction of the footrest 23 when the seat back 22 rotates can be obtained as leftward movement.

[0085] 2. When the first obstacle exists in the moving direction of the footrest 23 according to the shooting of the in-vehicle camera, and the category of the first obstacle is a B-class obstacle, the controller of the automobile seat 200 detects that the second distance is less than or equal to a2, then at this time the footrest 23 is unfolded, that is, the footrest 23 rotates counterclockwise to make the second distance equal to b2; similarly, when the category of the first obstacle is a C-class obstacle, the controller of the automobile seat 200 detects that the second distance is less than or equal to a3, then at this time the footrest 23 is unfolded, that is, the footrest 23 rotates counterclockwise to make the second distance equal to b3.

[0086] 3. When the second obstacle existing in the rotating direction of the footrest 23 is detected, the controller of the automobile seat 200 receives the third distance in the rotating process of the footrest 23. Taking the second obstacle as a B-class obstacle as an example, when the controller of the automobile seat 200 detects that the third distance is equal to a2 and the footrest 23 still needs to continue to rotate, the controller of the automobile seat 200 controls the footrest 23 to stop rotating and stops the adjustment of the seat back 22, thereby avoiding the collision of the footrest 23 with the first obstacle or the second obstacle.

[0087] 4、When the category of the first obstacle is A-class obstacle, since the A-class obstacle is movable, the first sensor 231 and the second sensor 232 simultaneously open sensing, and the principle is the same as that in step 3, which is not described herein again.

[0088] Compared with the related art, the embodiment of the application has at least the following advantages: after determining the rotation direction of the seat back adjustment, the moving direction of the footboard during the rotation of the seat back is obtained according to the rotation direction, so as to detect whether there is a first obstacle in the moving direction of the footboard. In the case where it is detected that there is a first obstacle in the moving direction, the footboard is controlled to rotate away from the first obstacle during the adjustment of the seat back, so as to effectively avoid the collision between the footboard and the obstacle during the adjustment of the seat back. Through the linkage of the seat back and the footboard, the adjustment of the automobile seat is more intelligent and reliable, and the use experience of the user is improved.

[0089] Please refer to Figure 7 , Figure 7 is a step flowchart of an embodiment of the control method of the automobile seat. The order of the steps in the flowchart can be changed according to different needs, and some steps can be omitted. The control method of the automobile seat can be applied to the automobile seat described above, but is not limited thereto, and the embodiments of the application are not limited in this regard.

[0090] This embodiment is a specific description of the foregoing embodiments, mainly illustrating that in the case where the seat back adjusts to the target rotation angle relative to the seat cushion, the footboard is controlled to rotate away from the first obstacle. In this way, it can be ensured that the footboard does not collide with the obstacle during the adjustment of the seat back, thereby further improving the reliability of the control method of the automobile seat.

[0091] The specific process of this embodiment is shown in Figure 7 , including the following steps:

[0092] Step 501: obtaining a rotation adjustment instruction for adjusting the seat back, wherein the rotation adjustment instruction includes a rotation direction of the seat back relative to the seat cushion.

[0093] Step 502: determining a moving direction of the footboard during the rotation of the seat back according to the rotation direction.

[0094] Step 503: in the case where it is detected that there is a first obstacle in the moving direction, obtaining a first distance between the current footboard and the first obstacle.

[0095] Step 504: calculating a moving distance of the footboard in the moving direction after the adjustment of the seat back is completed according to the target rotation angle and the rotation direction.

[0096] In some embodiments, the moving distance can be calculated by the following manner: obtaining a first rotation angle of the seat back relative to the seat cushion before the seat back is adjusted, and a second rotation angle of the footboard relative to the seat back; obtaining first position information of the footboard before the seat back is adjusted according to the first rotation angle and the second rotation angle; calculating a third rotation angle of the seat back relative to the seat cushion after the seat back is adjusted according to the first rotation angle and a target rotation angle; obtaining second position information of the footboard after the seat back is adjusted according to the third rotation angle and the second rotation angle; and determining the moving distance according to the first position information and the second position information.
