[0002] With the development of vehicle intelligence, the functions of seats in vehicles are increasing. On the one hand, the lumbar support function of the seat can relieve the user's waist fatigue. On the other hand, the backrest of the seat can be adjusted backwards to enable the user to lie (including lying flat, half lying, etc.) on the seat.

[0003] In actual situations, as the backrest position changes, the user's waist position will move accordingly. If the user has adjusted the position of the lumbar support before adjusting the backrest, the original lumbar support position may no longer match the user's waist position as the backrest position changes, resulting in reduced comfort for the user's waist and reduced user experience.

[0046] With the development of vehicle intelligence, the functions of seats in vehicles are becoming more and more. On the one hand, the lumbar support function of the seat can relieve the user's waist fatigue. At present, the lumbar support can include three air bags or two air bags. By adjusting the lumbar support switch to inflate or deflate the air bags, the lumbar support can support the user's waist and relieve the user's waist fatigue. On the other hand, with the development of smart cockpits, the cockpit has become a movable space. At present, the backrest of the seat can be adjusted backwards at an angle so that the user can lie on the seat. For example, the current vehicle seats can achieve zero gravity mode to improve the user's riding comfort.

[0047] Embodiments of the present application provide a control method, apparatus, device, storage medium, and vehicle.

[0048] The following first introduces the control method provided in the embodiment of the present application.

[0049] Figure 1 FIG. 1 is a flow chart of a control method provided by an embodiment of the present application. Figure 1 As shown, the control method provided in the embodiment of the present application includes the following steps:

[0050] S110, obtaining a first initial position of a backrest and a second initial position of a lumbar support;

[0051] S120, acquiring first movement information of the backrest during the process of the backrest moving from the first initial position to the first target position;

[0052] S130, determining second movement information of the lumbar support corresponding to the first movement information according to the correspondence between the movement information of the backrest and the movement information of the lumbar support;

[0053] S140, controlling the lumbar support to perform a movement operation corresponding to the second movement information, wherein the movement operation is used to control the lumbar support to move from the second initial position to the second target position, wherein the second target position is a position of the lumbar support corresponding to the user's waist when the backrest is in the first target position.

[0054] The control method of the embodiment of the present application obtains the first movement information of the backrest during the movement of the backrest from the first initial position to the first target position, and determines the second movement information of the lumbar support corresponding to the first movement information according to the correspondence between the movement information of the backrest and the movement information of the lumbar support, so that when the waist moves with the backrest, the second movement information of the lumbar support can be accurately determined. In this way, by controlling the lumbar support to perform the movement operation corresponding to the second movement information, that is, controlling the lumbar support to move from the second initial position to the second target position corresponding to the user's waist, the comfort of the user's waist can be guaranteed and the user experience can be improved.

[0055] The specific implementation methods of the above steps are introduced below.

[0056] In some embodiments, in S110, the backrest and the lumbar support may be located in the same seat. The lumbar support may include at least one air bag. The user may inflate or deflate the air bag through the lumbar support switch. The relative position relationship between the lumbar support and the waist may be adjusted by inflating or deflation of the air bag. In addition, the first initial position may be any position of the backrest, which is not limited here. The second initial position may be the position of the lumbar support corresponding to the user's waist when the backrest is in the first initial position.

[0057] As an example, when the backrest of the seat is in the first initial position, the user can adjust the lumbar support position through the lumbar support switch so that the lumbar support position can support the user's waist. If the user stops adjusting the lumbar support switch, the lumbar support position corresponding to the lumbar support switch at this time may be the second initial position.

[0058] In some embodiments, in S120, the first target position may be the position of the backrest after it moves from the first initial position. In addition, the movement information of the backrest may include position change information and angle change information. If the backrest moves forward and backward, the movement information of the backrest may be position change information. If the backrest rotates around an axis, the movement information of the backrest may be angle change information. Based on this, the first movement information may include target position change information and target angle change information.

[0059] As an example, a seat may include a backrest switch, a seat control module, and a backrest motor. During the process of the user adjusting the backrest switch, the backrest switch may send a first instruction to the seat control module. The first instruction may be used to notify the seat control module to drive the backrest to move. After receiving the first instruction, the seat control module may respond to the first instruction to drive the backrest motor to rotate, thereby enabling the backrest to rotate. In addition, the seat control module may include a Hall sensor. During the process of the backrest motor driving the backrest to rotate, the Hall sensor may read the rotation angle of the backrest motor (i.e., the backrest) in real time. That is, during the process of the backrest rotating, the seat control module may read the rotation angle of the backrest in real time to obtain the angle change information of the backrest (i.e., the first movement information).

[0060] In some embodiments, in S130, during the movement of the backrest, the user's waist position will move accordingly. Therefore, in order for the lumbar support to still support the user's waist after the backrest moves, the lumbar support may be moved corresponding to the lumbar position, that is, the lumbar support may be moved corresponding to the movement of the backrest. Therefore, the second movement information may be movement information that the lumbar support may move during the movement of the backrest in order for the lumbar support to still support the user's waist.

[0061] Based on this, as an example, there may be a corresponding relationship between the movement information of the backrest and the movement information of the lumbar support. In addition, the seat may include a lumbar support control module. The seat control module may send the first movement information to the lumbar support control module in real time. After obtaining the first movement information, the lumbar support control module may obtain the corresponding relationship and determine the second movement information based on the corresponding relationship. Among them, since the first movement information may be information obtained in real time, the second movement information may also be information determined in real time. That is, each time a first movement information is obtained, a second movement information may be immediately determined. In addition, since in actual situations, the time for the backrest to move from the first initial position to the first target position is short, the second movement information may be determined based on the corresponding relationship after the backrest stops moving.

[0062] Based on this, in order to save computing resources used to determine the second movement information, in some embodiments, the above S130 may specifically include:

[0063] When the first movement information does not change within a preset time period, second movement information of the lumbar support corresponding to the first movement information is determined according to the corresponding relationship between the movement information of the backrest and the movement information of the lumbar support.

[0064] Here, the preset time length may be, for example, 200 milliseconds, 300 milliseconds, etc., which is not limited here. If the first movement information does not change within the preset time length, it can be considered that the backrest has stopped moving, and the second movement information can be determined according to the corresponding relationship.

[0065] In this way, by determining the second movement information when the backrest stops moving, compared with continuously determining the second movement information during the movement of the backrest, the computing resources used for determining the second movement information can be saved.

[0066] In addition, since the waist support may include at least one air bag, the height of the air bag may be adjusted by inflating and deflating the air bag. Therefore, the movement information of the air bag may include inflation amount change information corresponding to at least one air bag. The inflation amount change information may include inflation volume change information, inflation weight change information, inflation time change information, etc. Based on this, the second movement information may include target inflation amount change information corresponding to at least one air bag.

[0067] Based on this, when the first movement information is target angle change information, in order to accurately determine the second movement information of the lumbar support, in some embodiments, the above S130 may specifically include:

[0068] For each air bag, target inflation amount change information corresponding to the target angle change information is determined according to the correspondence between the angle change information of the seat back and the inflation amount change information of the air bag.

[0069] Here, the inflation amount change information of each air bag may correspond to one angle change information. That is, in the case of three air bags, there may be three corresponding relationships.

[0070] As an example, if the lumbar support includes three air bags, namely the first air bag, the second air bag and the third air bag, there may be a first correspondence between the angle change information of the backrest and the inflation amount change information of the first air bag, there may be a second correspondence between the angle change information of the backrest and the inflation amount change information of the second air bag, and there may be a third correspondence between the angle change information of the backrest and the inflation amount change information of the third air bag. Based on this, the target inflation amount change information corresponding to the first air bag can be determined according to the first correspondence and the target angle change information. The target inflation amount change information corresponding to the second air bag can be determined according to the second correspondence and the target angle change information. The target inflation amount change information corresponding to the third air bag can be determined according to the third correspondence and the target angle change information.

[0071] In this way, by determining the target inflation volume change information corresponding to each air bag, the second movement information of the lumbar support can be accurately determined.

[0072] Based on this, in the case where the inflation amount change information is the inflation time change information, in order to improve the accuracy of the second movement information, in some embodiments, before determining the target inflation amount change information corresponding to the target angle change information based on the correspondence between the backrest angle change information and the inflation amount change information of the airbag, the following steps may also be included:

[0073] Acquire a mapping relationship between multiple angle change information of the backrest and multiple inflation time change information of the airbag;

[0074] The mapping relationship is fitted by a linear regression algorithm to obtain a linear regression equation, which is used to characterize the corresponding relationship between the angle change information and the inflation time change information.

[0075] Here, the correspondence between the angle change information of the seat back and the inflation amount change information of the air bag may be a linear correspondence.

[0076] As an example, the user can sit on the seat, adjust the backrest switch to make the backrest at an angle of θ1, and then adjust the lumbar support switch to inflate the two air bags respectively, and obtain the inflation time a1 of the first air bag and the inflation time b1 of the second air bag. After that, the user can continue to adjust the backrest switch to make the backrest at an angle of θ2, and then adjust the lumbar support switch to inflate the two air bags respectively, and obtain the inflation time a2 of the first air bag and the inflation time b2 of the second air bag. Based on this, the angle change information θ2-θ1, the inflation time change information a2-a1, and the inflation time change information b2-b1 can be obtained. Among them, the first mapping relationship can be between θ2-θ1 and a2-a1, and the second mapping relationship can be between θ2-θ1 and b2-b1. After that, the user can continue to adjust the backrest switch to make the backrest at an angle of θ3, and then adjust the lumbar support switch to inflate the two air bags respectively, and obtain the inflation time a3 of the first air bag and the inflation time b3 of the second air bag. Based on this, the angle change information θ3-θ1, the inflation time change information a3-a1, and the inflation time change information b3-b1 can be obtained. Among them, the third mapping relationship can be between θ3-θ1 and a3-a1, and the fourth mapping relationship can be between θ3-θ1 and b3-b1. Of course, the angle change information θ3-θ2, the inflation time change information a3-a2, and the inflation time change information b3-b2 can also be obtained. Among them, the fifth mapping relationship can be between θ3-θ2 and a3-a2, and the sixth mapping relationship can be between θ3-θ2 and b3-b2, which is not limited here.

[0077] Based on this, for the first airbag, the first mapping relationship and the third mapping relationship can be fitted by a linear regression algorithm to obtain a linear regression equation corresponding to the first airbag. Alternatively, the first mapping relationship and the fifth mapping relationship can be fitted by a linear regression algorithm to obtain a linear regression equation corresponding to the first airbag. Alternatively, the first mapping relationship, the third mapping relationship and the fifth mapping relationship can be fitted by a linear regression algorithm to obtain a linear regression equation corresponding to the first airbag. The same is true for the remaining airbags, which will not be described in detail here.

[0078] Based on this, in some embodiments, the linear regression equation may be specifically: Δm=Δθ / k, where Δm may be inflation time variation information, Δθ may be angle variation information, and 1 / k may be a constant coefficient.

[0079] As an example, when the waist support includes three air bags, three linear regression equations can be obtained by fitting the mapping relationship through a linear regression algorithm:

[0080] Δa=Δθ / k1 (1)

[0081] Δb=Δθ / k2 (2)

[0082] Δc=Δθ / k3 (3)

[0083] Among them, Δa may be the inflation time change information corresponding to the first airbag, Δb may be the inflation time change information corresponding to the second airbag, Δc may be the inflation time change information corresponding to the third airbag, Δθ may be the angle change information corresponding to the backrest, and 1 / k1, 1 / k2, and 1 / k3 may be constant coefficients corresponding to the three linear regression equations, respectively. The process of fitting the mapping relationship through the linear regression algorithm may specifically be the process of determining the constant coefficients.

[0084] In addition, in the linear regression equation, if Δa>0, the first airbag can be inflated, and if Δa<0, the first airbag can be deflated. The same is true for Δb and Δc, which will not be described in detail here.

[0085] Based on this, in some embodiments, the above-mentioned determination of the target inflation volume change information corresponding to the target angle change information based on the correspondence between the angle change information of the backrest and the inflation volume change information of the airbag may specifically include:

[0086] Substitute the target angle change information into the linear regression equation to obtain the target inflation time change information.

[0087] Here, for the first airbag, by substituting the target angle change information into the linear regression equation, the target inflation time change information corresponding to the first airbag can be obtained. The same is true for the other airbags, which will not be described in detail here.

[0088] In this way, the mapping relationship is fitted by a linear regression algorithm to obtain a linear regression equation, and the target inflation time variation information is determined based on the linear regression equation, so that the accuracy of the second movement information can be improved.

[0089] Based on this, in order to more finely control the lumbar support during the process of adjusting the backrest, in some embodiments, the angle change information in different intervals can correspond to different linear regression equations. For example, if the angle of the backrest changes from 0° to 50°, the target angle change information (50°) can be substituted into equation A. If the angle of the backrest changes from 50° to 100°, the target angle change information (50°) can be substituted into equation B. Among them, equation A and equation B can be different.

[0090] Based on this, in order to realize that the angle change information of different intervals can correspond to different linear regression equations, in some embodiments, before substituting the target angle change information into the linear regression equation, different linear regression equations can be fitted for the angle change information of different intervals. For example, for the angle change information of the interval (50°, 100°), the inflation time change information of the inflatable bag can be obtained in the process that user A adjusts the angle of the backrest from 50° to 100°. In the process that user B adjusts the angle of the backrest from 50° to 100°, the inflation time change information of the inflatable bag can be obtained. Among them, the height and weight of user A and user B can be different. According to the above method, multiple mapping relationships between angle change information and inflation time change information can be obtained through multiple different users. By linearly fitting multiple mapping relationships, a linear regression equation corresponding to the interval (50°, 100°) can be obtained. For another example, for the angle change information of the interval (50°, 100°), user A can adjust the angle of the backrest from 50° to 100° multiple times. Each time the backrest is adjusted, the inflation time change information of the air bag can be obtained, and multiple mapping relationships between the angle change information and the inflation time change information can be obtained. By linearly fitting the multiple mapping relationships, a linear regression equation corresponding to the interval (50°, 100°) can be obtained.

[0091] In some embodiments, in S140, the waist support control module may control the waist support to perform a movement operation corresponding to the second movement information, so that the waist support moves from the second initial position to the second target position.

[0092] Based on this, when the waist support includes multiple air bags, in order to ensure the comfort of the user's waist, in some embodiments, the above S140 may specifically include:

[0093] For each air bag, the air bag is controlled to perform an inflation or deflation operation corresponding to the target inflation amount change information.

[0094] Here, if the waist support includes three air bags, the second initial position may include, for example, the inflation time of the first air bag is a, the inflation time of the second air bag is b, and the inflation time of the third air bag is c. On this basis, if the target inflation amount change information of the first air bag is Δa, the target inflation amount change information of the second air bag is Δb, and the target inflation amount change information of the third air bag is Δc, and Δa<0, Δb>0, Δc>0, then the first air bag may be deflated based on the inflation time a to obtain a new inflation time a', the second air bag may be inflated based on the inflation time b to obtain a new inflation time b', and the third air bag may be inflated based on the inflation time c to obtain a new inflation time c' corresponding to the third air bag.

[0095] As an example, as shown in FIG2(a), the user has adjusted the inflation time of the first airbag 21 to 10 seconds, the inflation time of the second airbag 22 to 5 seconds, and the inflation time of the third airbag 23 to 3 seconds when the backrest is 5°. In addition, the constant coefficients of the linear regression equations corresponding to the three airbags can be k1=-4, k2=5, and k3=10, respectively. As shown in FIG2(b), when the user adjusts the backrest to 25°, it can be seen that Δθ=20°. In this way, by substituting Δθ into the linear regression equations (1), (2), and (3), we can obtain Δa=-5, Δb=4, and Δc=2. Based on the above, the first airbag 21 can be deflated for 5 seconds, the second airbag 22 can be inflated for 4 seconds, and the third airbag 23 can be inflated for 2 seconds.

[0096] In this way, by controlling each air bag to perform an inflation or deflation operation corresponding to the target inflation amount change information, the height of each air bag can be made to correspond to the user's waist, thereby ensuring the comfort of the user's waist.

[0097] In order to better describe the entire solution, some specific examples are given based on the above embodiments.

[0098] For example, Figure 3As shown, the seat may include a backrest switch, a seat control module, a backrest motor, a lumbar support switch, a lumbar support control module and three air bags (a first air bag, a second air bag and a third air bag). After the user sits on the seat, the lumbar support switch can be adjusted so that the lumbar support control module controls the three air bags to inflate and deflate respectively, so that the three air bags can support the user's waist and ensure the comfort of the user's waist. If the user adjusts the backrest switch to rotate the backrest backward, the backrest switch can send a first instruction to the seat control module during the user's adjustment of the backrest switch. The first instruction can be used to notify the seat control module to drive the backrest to move. After receiving the first instruction, the seat control module can respond to the first instruction to drive the backrest motor to rotate, thereby enabling the backrest to rotate. In addition, the seat control module may include a Hall sensor. In the process of the backrest motor driving the backrest to rotate, the Hall sensor can read the rotation angle of the backrest motor (i.e., the backrest) in real time. That is, in the process of the backrest rotating, the seat control module can read the rotation angle of the backrest in real time, obtain the angle change information of the backrest, and send the angle change information to the lumbar support control module in real time. When the waist support control module detects that the angle change information has not changed within 200 milliseconds, the corresponding relationship between the angle change information and the inflation time change information can be obtained for each air bag, and the inflation time change information corresponding to the angle change information can be calculated. For each air bag, after obtaining the inflation time change information, the waist support control module can control the air bag to perform inflation and deflation operations corresponding to the inflation time change information, so that the three air bags can continue to support the user's waist and ensure the comfort of the user's waist.

[0099] Therefore, by automatically adjusting the lumbar support position when the user adjusts the backrest, compared with the user manually adjusting the lumbar support switch to adjust the retracted position, the user operation can be simplified and the user experience can be improved.

[0100] Based on the control method provided in the above embodiment, the present application also provides a specific implementation of the control device. Please refer to the following embodiment.

[0104] A determination module 430, configured to determine second movement information of the lumbar support corresponding to the first movement information according to a correspondence between the movement information of the backrest and the movement information of the lumbar support;

[0105] The control module 440 is used to control the lumbar support to perform a movement operation corresponding to the second movement information, and the movement operation is used to control the lumbar support to move from the second initial position to the second target position.
