[0026] Exemplary Methods

[0027] The vehicle seat linkage adjustment method provided by the embodiment of the present disclosure can be applied to the main controller of the vehicle, and can also be applied to other terminals, servers, etc. that can communicate with the vehicle.

[0028] The vehicle seat linkage adjustment method provided by the embodiment of the present disclosure is as follows: Figure 1 As shown, it mainly includes the following steps:

[0029] Step 101 , obtaining the front row characterization point position of the front seat and the rear row characterization point position of the rear seat of the vehicle, as well as the front row backrest height of the front seat and the rear row backrest height of the rear seat.

[0030] In some embodiments, the front row characterizing point position is the axis center of the connecting shaft between the seat cushion and the backrest of the front row seat; the rear row characterizing point position is the axis center of the connecting shaft between the seat cushion and the backrest of the rear row seat.

[0031] The front seat characterization point represents the position of the front seat, while the rear seat characterization point represents the position of the rear seat. The axis connecting the front seat cushion and backrest is used as the front seat characterization point, and the axis connecting the rear seat cushion and backrest is used as the rear seat characterization point. This provides a data basis for accurately calculating critical positions where front and rear seat adjustments may interfere.

[0032] For example, the front row characterization point position can be detected by the front row seat position sensor. Similarly, the rear row characterization point position can be detected by the rear row seat position sensor. The front row seat position sensor and the rear row seat position sensor can be calibrated in advance so that the front row characterization point position and the rear row characterization point position are expressed based on the same coordinate system.

[0033] For example, the specific values ​​of the front row backrest height and the rear row backrest height can be measured in advance and stored, and can be read from the storage location when in use.

[0034] Step 102 : determining a critical position of linkage between the front row seat and the rear row seat according to the front row characterizing point position, the front row characterizing point position, the front row backrest height, and the rear row backrest height.

[0035] In some embodiments, the critical position of the linkage between the front and rear seats is determined based on the front characterization point position, the rear characterization point position, the front backrest height, and the rear backrest height, including: constructing a first circle with the front characterization point position as the first center and the front backrest height as the first radius; constructing a second circle with the rear characterization point position as the second center and the rear backrest height as the second radius; determining a line connecting the first center and the second center, and determining a target intersection point among the two intersection points of the first circle and the second circle, the target intersection point being located on the side facing the roof; determining the critical position of the linkage between the front and rear seats based on the target intersection point, the first center, and the second center.

[0036] like Figure 2 The figure shows the positional relationship between the first circle, the second circle and the target intersection, where point O is the center of the first circle and point A is the center of the second circle; Figure 2 The circle on the middle left is the first circle with point O as the center and the height of the front row seat backrest as the radius; Figure 2The circle on the right side is: the second circle with point A as the center and the rear backrest height as the radius. Point B obtained by the intersection of the first circle and the second circle is the target intersection. Among them, the critical position of the front and rear linkage and the rear linkage can be determined according to the position of point B. It should be noted that the first circle is the coordinate origin, that is, point O, which is only an example case. When the center of the first circle is not point O, the coordinates of the center of the first circle are obtained by measuring the x-axis coordinate value and the y-axis coordinate value according to the seat position sensor. The XY coordinate system can be determined based on the pre-calibrated initial position of the front seat, and the coordinate origin O is the axis center of the connection axis between the seat cushion and the backrest of the front seat at the initial position. The unit of the coordinate system can be millimeters (mm).

[0037] In some embodiments, determining the critical position of the linkage between the front seat and the rear seat based on the target intersection, the first center of the circle and the second center of the circle includes: determining the distance value between the first center of the circle and the second center of the circle, and determining the critical distance value based on the distance value; wherein, the critical distance value is used to indicate the critical position where the front seat and the rear seat move forward and backward and collide; determining the collision critical point based on the target intersection; wherein, the collision critical point is used to indicate the critical position where the front seat and the rear seat backrest rotate and collide; determining the critical position includes the critical distance value and the collision critical point.

[0038] For example, a certain distance margin is added to the distance between the first and second center points to serve as the critical distance value. The specific value of this margin can be a pre-configured empirical value based on experience. This added margin provides sufficient space for front and rear seats to avoid each other.

[0039] Exemplarily, the critical position is adjusted so that the first angle value increases by a certain angle margin, which serves as the maximum position at which the front seat can recline when the rear seat backrest rotates counterclockwise. The first angle value is the angle formed by the line connecting the critical position and the center of the first circle, and the line connecting the center of the first circle and the center of the second circle.

[0040] Exemplarily, the critical position is adjusted so that the second angle value increases by a certain angle margin, which serves as the maximum position that the rear seat can reach counterclockwise when the front seat backrest rotates clockwise. The second angle value is the angle formed by the line connecting the critical position and the second center of the circle, and the line connecting the first center of the circle and the second center of the circle.

[0041] See also Figure 2As shown, the distance OA between the first circle center point O and the second circle center point A is used to determine the critical distance value. The critical collision point is determined based on the position of point B, which can be directly used as the critical collision point. The lengths of the three sides of the triangle △OBA are known. According to the law of cosines, the angle ∠α can be calculated. Based on the coordinates of point A, the angle ∠β can be calculated. Avoidance control is performed based on the values ​​of ∠α and ∠β to facilitate control within the avoidance range defined by the critical collision point.

[0042] Step 103 : When adjusting the front seats, controlling the rear seats to be linked according to the critical position; or, when adjusting the rear seats, controlling the front seats to be linked according to the critical position.

[0043] In some embodiments, the critical position includes a collision critical point; the collision critical point is used to indicate a critical position where the front seat and the rear seat backrest rotate and collide;

[0044] When adjusting the front seats, controlling the linkage of the rear seats according to the critical position includes:

[0045] If the rear seat backrest is not within a first target range, it is not necessary to adjust the rear seat in conjunction with the front seat backrest angle; wherein the first target range is a range covered by a first connecting line rotated counterclockwise from the rear row representative point position to the position of a second connecting line, the first connecting line being a line connecting the collision critical point and the rear row representative point position, and the second connecting line being a line connecting the front row representative point position and the rear row representative point position;

[0046] or

[0047] If the rear seat backrest is within the first target range and the estimated position of the front seat backrest after angle adjustment is also within the first target range, controlling the rear seat to rotate clockwise to leave the first target range before adjusting the backrest angle of the front seat;

[0048] or

[0049] If the rear seat backrest is within the first target range and the estimated position of the front seat backrest after angle adjustment is not within the first target range, there is no need to link the rear seat when adjusting the backrest angle of the front seat;

[0050] or

[0051] If the rear seat backrest is within the first target range, before adjusting the front seat backrest angle, the rear seat backrest angle is linked to be adjusted to leave the first target range.

[0052] See also Figure 2 As shown, the critical collision point is point B, and the first target range is the range covered by counterclockwise rotation from BA to OA. When the rear seatback is not within the first target range, clockwise rotation of the front seatback, even past point B, will not interfere with the rear seatback. In other words, clockwise or counterclockwise rotation of the front seatback will not interfere with the rear seatback, eliminating the need to coordinate with the rear seatback when adjusting the front seatback angle. When the rear seatback is within the first target range, coordination is required based on the projected position of the front seatback after adjustment. Alternatively, as long as the rear seatback is within the first target range, regardless of the projected position of the front seatback after adjustment, the rear seatback should be coordinated and adjusted to leave the first target range before adjusting the front seatback.

[0053] In some embodiments, the critical position includes a collision critical point; the collision critical point is used to indicate a critical position where the front seat and the rear seat backrest rotate and collide;

[0054] When adjusting the rear seats, controlling the front seats to be linked according to the critical position includes:

[0055] If the front seat backrest is not in the second target range, it is not necessary to adjust the front seat backrest angle in conjunction with adjusting the rear seat backrest angle; wherein the second target range is the range covered by the third connecting line rotating clockwise from the front row representative point position to the position of the second connecting line, the third connecting line is the line connecting the collision critical point and the front row representative point position, and the second connecting line is the line connecting the front row representative point position and the rear row representative point position;

[0056] or

[0057] If the front seat backrest is within the second target range and the estimated position of the rear seat backrest after angle adjustment is also within the second target range, controlling the front seat to rotate counterclockwise to leave the second target range before adjusting the rear seat backrest angle;

[0058] or

[0059] If the front seat backrest is within the second target range and the expected position of the rear seat backrest after angle adjustment is not within the second target range, it is not necessary to link the front seat when adjusting the rear seat backrest angle;

[0060] or

[0061] If the front seat back is within the second target range, the front seat back is adjusted to leave the second target range before adjusting the rear seat back.

[0062] See also Figure 2 As shown, the second target range is defined as the critical collision point, point B, and the second target range is the range covered by the clockwise rotation of OB to OA. When the front seatback is not within the second target range, counterclockwise rotation of the rear seatback, even past point B, will not interfere with the front seatback. In other words, clockwise or counterclockwise rotation of the rear seatback will not interfere with the front seatback, eliminating the need to coordinate with the front seatback when adjusting the rear seatback angle. When the front seatback is within the second target range, coordination is required based on the expected position of the rear seatback after adjustment. Alternatively, as long as the front seatback is within the second target range, regardless of the expected position of the rear seatback after adjustment, the front seatback should be coordinated and adjusted to leave the second target range before adjusting the rear seatback.

[0063] The first and second target ranges can be the same. When setting margins for the front and rear seats, the first and second target ranges may differ slightly. For example, the second target range can be the range covered by rotating BO clockwise to OB, as described above, plus the margin for rotating BO counterclockwise. The first target range can be the range covered by rotating BA counterclockwise to OA, plus the margin for rotating BA clockwise.

[0064] In some embodiments, the critical position includes a critical distance value, and the critical distance value is used to indicate a critical position where the front seat and the rear seat move forward and backward and collide;

[0065] The method of controlling the linkage of the rear seats according to the critical position when adjusting the front seats or controlling the linkage of the front seats according to the critical position when adjusting the rear seats includes:

[0066] When adjusting the front seat forward and backward movement, controlling the rear seat forward and backward movement according to the critical distance value so that the relative distance between the front row representative point position and the rear row representative point position during the entire adjustment process is not less than the critical distance value;

[0067] or

[0068] When adjusting the forward and backward movement of the rear seats, the forward and backward movement of the front seats is controlled according to the critical distance value so that the relative distance value between the front row characterizing point position and the rear row characterizing point position is not less than the critical distance value during the entire process.

[0069] See also Figure 2 As shown, the length value of OA is the critical distance value or the length value of OA plus a certain distance margin. When adjusting the front seats (or rear seats) to move forward and backward, the rear seats (or front seats) are adjusted synchronously to keep the relative distance value of the two rows of seats not less than the critical distance value.

[0070] In some embodiments, the critical position of the linkage between the front row seats and the rear row seats is determined based on the front row characterization point position, the front row characterization point position, the front row backrest height and the rear row backrest height, including: determining the backrest position of the rear row seat after being folded down counterclockwise based on the rear row characterization point position and the rear row backrest height; determining the maximum elevation angle value of the front row seat backrest when rotating clockwise based on the backrest position and the front row characterization point position; and determining the critical position of the linkage between the front row seat and the rear seat based on the maximum elevation angle value.

[0071] Among them, the maximum tilt angle value of the front seat when it is rotated clockwise is used to ensure that when the front seat backrest is rotated clockwise to the maximum tilt angle value, it will not interfere with the rear seat that is folded down counterclockwise.

[0072] Among them, the method for determining the backrest position after the rear seat is folded down counterclockwise includes: pre-calibrating the relative position relationship between the representation point of the backrest headrest and the rear representation point after the rear seat is folded down counterclockwise, and the relative position will not change due to the forward and backward movement of the rear seat; based on the relative position relationship and the current position of the rear representation point, the backrest position of the rear seat after being folded down counterclockwise can be determined.

[0073] The representative point of the headrest can be the point on the headrest that is closest to the roof when the rear seat is folded down counterclockwise.

[0074] Exemplarily, the maximum elevation angle value of the front seat backrest when rotating clockwise is determined based on the backrest position and the front row characterization point position, including: obtaining the angle value between the line connecting the backrest position and the front row characterization point position and the plane where the front seat cushion is located, and determining the maximum elevation angle value based on the angle value.

[0075] For example, the included angle value is directly used as the maximum elevation angle value. In another example, a certain elevation angle margin is subtracted from the included angle value, and the resulting angle value is used as the maximum elevation angle value; the elevation angle margin can be a pre-configured empirical value.

[0076] For example, Figure 3The position of the rear seat backrest is shown as being laid down counterclockwise, and the C point is the backrest position when the rear seat backrest is laid down counterclockwise. The backrest position can be the coordinates of any one point of the backrest headrest position, for example, the backrest position is the coordinates of the point on the headrest closest to the roof after the backrest is laid down counterclockwise. The angle value between the OC line and the negative direction of the x-axis is obtained, and the angle value is taken as the maximum reclining angle value of the front seat backrest clockwise rotation, or the angle value is reduced by a certain reclining angle allowance (for example, 5 degrees) and then taken as the maximum reclining angle value.

[0077] In some embodiments, when adjusting the rear seat, the front seat linkage is controlled according to the critical position, including: recording a first reclining angle value of the front seat before avoiding the counterclockwise laying down operation of the rear seat; when the first reclining angle value is greater than or equal to the maximum reclining angle value, determining the target reclining angle value as the maximum reclining angle value, and when the first reclining angle value is less than the maximum reclining angle value, determining the target reclining angle value as the first reclining angle value; after adjusting the rear seat to be laid down counterclockwise, the front seat is returned from a second reclining angle after avoiding the counterclockwise operation of the rear seat to the target reclining angle value.

[0078] Referring to Figure 3 As shown, the rear seat backrest is laid down, and the front seat triggers a return. According to the coordinates of the position point C after the rear seat backrest is laid down, the maximum reclining angle value of the front seat backrest can be calculated. If the front seat backrest position before avoiding is lower than the position corresponding to the maximum reclining angle value, the front seat backrest is returned to the position corresponding to the maximum reclining angle value, and if it is higher than the position corresponding to the maximum reclining angle value, the front seat backrest is returned to the original position before avoiding.

[0079] The embodiments provided by the present disclosure can automatically determine the critical position of the linkage of the front seat and the rear seat for a vehicle that needs seat linkage adjustment by obtaining the front seat position of the front seat of the vehicle and the rear seat position of the rear seat, and the front seat backrest height of the front seat and the rear seat backrest height of the rear seat. When adjusting the front seat, the linkage of the rear seat is controlled according to the critical position, or when adjusting the rear seat, the linkage of the front seat is controlled according to the critical position. Thus, for different types of vehicles, the critical position suitable for the vehicle can be determined, and when adjusting the front seat or the rear seat, the linkage is adjusted through the critical position to realize automatic linkage and avoidance. This method does not need to be pre-calibrated with a large amount of data, is efficient, and can be adapted to all vehicles.

[0080] The embodiments provided by the present disclosure can fundamentally solve the interference problem during seat adjustment, can ensure active linkage and avoidance during seat adjustment, make the seat function more intelligent, and reflect the function performance of high-end seats.
