[0061] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0062] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in the present invention are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and corresponding operation entrances shall be provided for users to choose to authorize or refuse.

[0063] First, the application scenarios of the present invention are explained.

[0064] Electric adjustable seats or multi-functional seats (hereinafter referred to as vehicle seats or seats) mainly use motors to drive the various adjustment components of the vehicle seats to adjust the vehicle seats in multiple aspects such as backrest, leg support, seat height, lumbar support, etc., to improve user comfort.

[0065] Figure 1 Schematic diagram of the structure of a vehicle seat is shown. Figure 1 As shown, the vehicle seat includes a leg rest, a seat cushion and a backrest. Among them, the front and rear seat adjustment motor of the vehicle seat is installed on the front and rear slide rails to realize the front and rear movement of the vehicle seat; the seat height adjustment motor is installed at the bottom of the vehicle seat to realize the height adjustment of the vehicle seat; the seat back adjustment motor is installed inside the backrest and connected to the backrest adjustment mechanism to adjust the backrest angle; the seat leg rest adjustment motor is installed at the connection between the seat cushion and the leg rest to adjust the angle of the leg rest.

[0066] In actual applications, the vehicle is equipped with buttons to control the movement of each motor. By pressing the corresponding button, the user can easily adjust the backrest, leg rest and other parts. For example, when the backrest angle needs to be adjusted, press the backrest adjustment button, and the seat back adjustment motor will drive the backrest to slowly and smoothly adjust to the angle the user wants.

[0067] It should be understood that, in the present invention, the front refers to the driving direction of the vehicle, and the rear refers to the direction opposite to the driving direction of the vehicle.

[0068] However, when adjusting the various components, the leg rest may easily collide with the front and rear slide rails of the vehicle seat, thereby causing the leg rest to be easily damaged.

[0069] Based on the above technical problems, the inventor discovered during a study of the adjustment process of the vehicle seat that, when other motors remain stationary, only the seat back adjustment motor will be adjusted so that the leg rest will not collide with the front and rear rails. However, as long as other motors except the seat back adjustment motor are adjusted, there is a possibility that the leg rest will collide with the front and rear rails. Therefore, when a user wants to adjust the vehicle seat, the seat height, the front and rear position of the seat, the leg rest angle, and the seat cushion angle can be determined after adjustment to further determine whether the leg rest will collide with the front and rear rails after adjustment. If it is determined that the leg rest will collide with the front and rear rails after adjustment, then based on the user's adjustment, the leg rest angle is increased to raise the user's legs, thereby avoiding the collision of the leg rest with the front and rear rails, thereby improving the accuracy of vehicle seat control.

[0070] The technical solution of the present invention is described in detail below through specific embodiments.

[0071] It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0072] Figure 2 FIG. 1 is a flow chart showing an embodiment of a method for adjusting a vehicle seat provided by the present invention, wherein the method is executed by a vehicle. Figure 2 As shown, the method comprises the following steps:

[0073] Step 210: According to the adjustment request for the vehicle seat, a first seat state parameter group after the adjustment request is executed is obtained.

[0074] In actual applications, the vehicle will be provided with buttons for controlling the vehicle seats. The button can be a physical button installed on the side of the vehicle seat or the door interior panel, or it can be a virtual control set in the central control screen. When the user wants to adjust the vehicle seat, he can do so by clicking the button. For example, for the vehicle height, two corresponding buttons are provided in the vehicle, namely "seat raise" and "seat lower". When the user needs to raise the seat, he only needs to click the "seat raise" button, and the vehicle will respond to the user's click on the "seat raise" button and generate an adjustment request for the vehicle seat.

[0075] Exemplarily, the vehicle seat in the embodiment of the present invention is the above-mentioned electrically adjustable seat or multifunctional seat, and may also be other existing vehicle seats that can be adjusted, and the embodiment of the present invention does not impose specific restrictions on this.

[0076] Optionally, the vehicle seat may be a front passenger seat, a driver seat, or a rear seat. The embodiment of the present invention does not impose any specific restriction on the position of the vehicle seat in the vehicle.

[0077] Among them, the first seat state parameter group includes parameters of various adjustable items, and each adjustable item includes seat height, seat front and rear position, leg rest angle and seat cushion angle.

[0078] In a possible implementation, since the leg rest will not collide with the front and rear rails when only the backrest is adjusted, after the vehicle generates an adjustment request for the vehicle seat, it can determine whether the adjustment request is for the backrest. If so, the adjustment request is directly executed to adjust the backrest. If not, the first seat state parameter group after the adjustment request is executed is obtained according to the adjustment request.

[0079] For example, assume that the "seat raise" button is configured to control the vehicle seat to raise a centimeter each time it is clicked, and the current seat height is A centimeters. After the user clicks the "seat raise" button, the vehicle responds to the user's click operation on the "seat raise" button and generates an adjustment request for the vehicle seat to request that the seat height be adjusted to A+a centimeters. In this scenario, the first seat state parameter group after executing the adjustment request includes: seat height: A+a centimeters, seat front and rear position: current front and rear position, leg rest angle: current leg rest angle, and seat cushion angle: current seat cushion angle.

[0080] Step 220: Determine whether the leg rest collides with the front and rear slide rails of the vehicle seat when the vehicle seat is in the first seat state parameter group.

[0081] In a possible implementation, the target interference flag state corresponding to the first seat state parameter group can be determined according to the preset mapping relationship and the first seat state parameter group. Then, it is determined whether the target interference flag state is the first state to determine whether the leg rest will collide with the front and rear rails.

[0082] The preset mapping relationship is used to represent the corresponding relationship between the seat state parameter group and the interference flag state. When the vehicle seat is in the seat state parameter group corresponding to the first state, the leg rest will collide with the front and rear slide rails.

[0083] In this implementation, the preset mapping relationship may be acquired in advance from other data storage devices, received in advance from a server, or established in advance. The embodiment of the present invention does not specifically limit the acquisition method of the preset mapping relationship.

[0084] It should be understood that the establishment of the preset mapping relationship will be explained in subsequent embodiments and will not be repeated here.

[0085] In this implementation, it is considered that any one of the factors of seat height, seat front and rear position, leg rest angle and cushion angle will affect the collision between the leg rest and the front and rear slide rails, and there are only two states of collision and non-collision in the collision situation. Therefore, the first state of the interference flag state can be used to indicate the collision, and the second state can be used to indicate the non-collision. Based on this, a mapping relationship can be created or obtained in advance, and the corresponding interference flag state under different combinations of seat height, seat front and rear position, leg rest angle and cushion angle can be represented by this mapping relationship. In this way, when the user adjusts the vehicle seat, it can be quickly determined whether the rear leg rest will collide with the front and rear slide rails according to the mapping relationship, thereby increasing the speed of adjusting the vehicle seat.

[0086] Step 230: If the leg rest will collide with the front and rear rails, the leg rest angle parameter value in the first seat state parameter group is increased to raise the user's legs, thereby generating a second seat state parameter group.

[0087] Considering that the front and rear position of the seat, the seat height and the cushion angle are important factors that affect the user's personalized needs for comfort. Therefore, when it is determined that the leg rest will collide with the front and rear rails, the leg rest angle parameter value in the first seat state parameter group can be increased to keep the front and rear position of the seat, the seat height and the cushion angle unchanged. When the vehicle seat is adjusted in response to the adjustment request, the leg rest is linked to raise the leg rest. In this way, not only can the occurrence of collisions be avoided, but also the personalized needs of users for vehicle seat adjustment will not be affected.

[0088] In a possible implementation, the parameter value of the leg rest angle in the first seat state parameter group can be added to the preset angle to generate a second seat state parameter group, wherein, except for the leg rest angle, the other parameter values ​​in the second seat state parameter group are the same as those in the first seat state parameter group.

[0089] For example, it is assumed that the first seat state parameter group includes seat height 1, seat front and rear position 1, leg rest angle 1, and cushion angle 1, and the preset angle is angle 1. When it is determined that the leg rest will collide with the front and rear rails, the generated second seat state parameter group includes seat height 1, seat front and rear position 1, leg rest angle 1+angle 1, and cushion angle 1.

[0090] It should be understood that the preset angle can be set according to experimental data or empirical values, and the embodiment of the present invention does not specifically limit this.

[0091] In another possible implementation, the parameter value of the leg rest angle in the first seat state parameter group may be multiplied by a preset coefficient to obtain an angle increment. Then, the parameter value of the leg rest angle in the first seat state parameter group is added to the angle increment to generate a second seat state parameter group. The specific implementation process may refer to the implementation method of adding the parameter value of the leg rest angle to the preset angle, which will not be repeated here.

[0092] Step 240: Adjust the vehicle seat based on the second seat state parameter group.

[0093] After determining the second seat state parameter group, the adjustable items of the vehicle seat can be adjusted to the second seat state parameter group. In this way, it can ensure that the user's personalized needs for comfort can be met and the risk of collision between the leg rest and the front and rear rails can be avoided.

[0094] The vehicle seat adjustment method provided by the embodiment of the present invention obtains the first seat state parameter group after executing the adjustment request according to the adjustment request for the vehicle seat. Then, it is judged whether the leg rest will collide with the front and rear slide rails of the vehicle seat when the vehicle seat is in the first seat state parameter group. If the leg rest will collide with the front and rear slide rails, the leg rest angle parameter value in the first seat state parameter group is increased to raise the user's legs, generate the second seat state parameter group, and finally, based on the second seat state parameter group, the vehicle seat is adjusted. Among them, the first seat state parameter group includes parameters of each adjustable item, and each adjustable item includes seat height, seat front and rear position, leg rest angle and cushion angle. In this technical solution, it is considered that the seat height, seat front and rear position, leg rest angle and cushion angle will cause the leg rest to collide with the front and rear slide rails. Therefore, when the user wants to adjust the vehicle seat, it is determined whether there is a collision risk through the adjusted first seat state parameter group, so that when there is a collision risk, the thigh rest angle parameter value is adjusted to raise the user's legs to avoid the occurrence of collision, thereby avoiding damage to the leg rest due to collision, and improving the adjustment accuracy of the vehicle seat.

[0095] Optionally, in some embodiments, if the leg rest will not collide with the front and rear slide rails of the vehicle seat when it is determined that the vehicle seat is in the first seat state parameter group, the adjustment request can be directly executed to adjust the adjustable items of the vehicle seat to the first seat state parameter group.

[0096] Next, based on the above embodiment, the process of creating a preset mapping relationship is explained.

[0097] According to the adjustable parameter range of each adjustable item, the parameter values ​​of any three adjustable items are fixed to the minimum parameter value, and the parameter values ​​of the remaining adjustable items are gradually increased from the minimum parameter value until the parameter values ​​of the remaining adjustable items are adjusted to the maximum parameter value or the leg rest collides with the front and rear rails, and the current parameter values ​​of the remaining adjustable items are obtained. After that. The range between the minimum parameter value and the current parameter value of the remaining adjustable items is determined as the interference range corresponding to the remaining adjustable items. Finally, a preset mapping relationship is constructed according to the interference range corresponding to each adjustable item.

[0098] Among them, the minimum parameter value of the seat height corresponds to the lowest adjustable position of the vehicle seat, the minimum parameter value of the seat front and rear position corresponds to the last adjustable position of the vehicle seat, the leg rest angle is the angle between the leg rest and the first direction, the seat cushion angle is the angle between the seat cushion and the second direction, the first direction is the downward direction perpendicular to the ground, and the second direction is the forward direction parallel to the ground.

[0099] In the above embodiment, when the leg rest collides with the front and rear rails, the limit parameter value of each adjustable item (i.e., the above current parameter value) can be determined in turn, and then the interference range corresponding to each adjustable item can be determined. In this way, when the parameter value of each adjustable item is within the corresponding interference range, it means that the position of each motor has entered the interference interval at this time. In this interference interval, there is a risk of collision between the leg rest and the front and rear rails. Based on this, the above preset mapping relationship can be quickly constructed. In this preset mapping relationship, when the parameter value of each adjustable item is within the corresponding interference range, the corresponding interference flag state is the first state; when the parameter value of any adjustable item is outside the corresponding interference range, the corresponding interference flag state is the second state.

[0100] For example, the first direction and the second direction can refer to Figure 1 Direction marked in .

[0101] Exemplarily, next, the process of creating the above preset mapping relationship is explained through a specific example.

[0102] First, determine the adjustable parameter range of each adjustable item, as shown below:

[0103] Seat front and rear position: front 100%, rear 0%, accuracy 1%

[0104] Seat height: 100% maximum, 0% minimum, 1% accuracy

[0105] Seat angle: 100% reclined, 0% leaned, 1% accuracy

[0106] Leg rest angle: 100% for the most upward position, 0% for the most downward position, 1% accuracy

[0107] It should be understood that an accuracy of 1% means that each time the user clicks a button, the vehicle will adjust by 1% in response to the user's operation.

[0108] Furthermore, the seat fore-and-aft position, seat height, seat cushion angle and seat cushion angle are all adjusted to 0%, that is, the seat fore-and-aft position is adjusted to the last position, the seat height is adjusted to the lowest, the angle of the seat cushion with the second direction is adjusted to the minimum, and the angle of the leg rest with the first direction is adjusted to the minimum.

[0109] Then, fix the seat height, seat front and rear position, and leg rest angle, and gradually increase the parameter value of the seat cushion angle until the angle between the seat cushion and the second direction is adjusted to the maximum or the leg rest collides with the front and rear slide rails, obtain the current parameter value (z) of the seat cushion angle, and adjust the angle between the seat cushion and the second direction to the minimum.

[0110] Similar to the seat cushion angle, the seat height, seat front and rear position, and seat cushion angle are fixed, and the parameter value of the leg rest angle is gradually increased until the angle between the leg rest and the first direction is adjusted to the maximum or the leg rest collides with the front and rear slide rails, the current parameter value (y) of the leg rest angle is obtained, and the angle between the leg rest and the first direction is adjusted to the minimum.

[0111] The seat height and the seat front and rear position are processed in accordance with the above method to obtain the current parameter value (w) of the seat height and the current parameter value (x) of the seat front and rear position.

[0112] It should be understood that the interference ranges corresponding to different adjustable items can be represented by the following Table 1.

[0113] Table 1

[0114] Height value Front and rear position value Leg rest angle Seat angle value Interference range Seat height w 0 0 0 (0，w) Seat front and rear position 0 x 0 0 (0，x) Leg rest angle 0 0 y 0 (0，y) Seat Angle 0 0 0 z (0，z)

[0115] It can be seen from Table 1 that when the seat height is at (0, w), the seat front-to-back position is at (0, x), the leg rest angle is at (0, y), and the seat cushion angle is at (0, z) at the same time, there is a risk of collision between the leg rest and the front and rear rails. Therefore, a parameter value is randomly selected from the corresponding interference interval for each adjustable item to form an initial interference parameter value group, and the interference flag state corresponding to the interference parameter value group is determined to be the first state, so as to construct the above-mentioned preset mapping relationship.

[0116] Further, a non-interference parameter value group is determined according to the adjustable parameter range of each adjustable item. When the parameter value of any adjustable item in the non-interference parameter value group is outside the corresponding interference range, the corresponding interference flag bit state is the second state.

[0117] Exemplarily, the non-interference parameter value group can be represented by the following Table 2.

[0118] Table 2

[0119]

[0120] Furthermore, since the interference area composed of the interference ranges corresponding to the adjustable items is the area where the leg rest collides with the front and rear rails, there are still some initial interference parameter value groups in the area that will not cause the leg rest to collide with the front and rear rails. Therefore, the above interference area can be further refined and the initial interference parameter value groups can be further screened.

[0121] Specifically, a simulation model of a vehicle seat can be constructed by virtual prototyping technology. Afterwards, parameter values ​​are randomly selected from the interference range corresponding to each adjustable item to construct a test seat state parameter group (initial interference parameter value). Then, based on the simulation model, it is determined whether the vehicle seat will collide with the front and rear rails when it is in the test seat state parameter group, and the interference flag state corresponding to the test seat state parameter is generated. According to the test seat state parameter and the corresponding interference flag state, a preset mapping relationship is constructed.

[0122] Among them, by determining from the initial interference parameter values ​​the initial interference parameter value that will not actually cause the leg rest to collide with the front and rear slide rails, and determining the interference flag state corresponding to the determined initial interference parameter value as the first state, and determining the interference flag state corresponding to the remaining initial interference parameter values ​​as the second state, the accuracy of the established preset mapping relationship is improved.

[0123] Optionally, based on the above embodiment, in step 220, if the above preset mapping relationship is created based on the interference area, and the above preset mapping relationship only includes the correspondence between the initial interference parameter value and the interference flag state, it can be first determined whether the parameters of each adjustable item included in the first seat state parameter group are all within the interference range corresponding to the adjustable item. If the parameters of each adjustable item included in the first seat state parameter group are all within the interference range corresponding to the adjustable item, then the target interference flag state corresponding to the first seat state parameter group is determined according to the preset mapping relationship and the first seat state parameter group.

[0124] In this embodiment, when the parameters of each adjustable item are within the interference range corresponding to the adjustable item, it indicates that there may be a collision risk; and when the parameters of any adjustable item are not within the interference range corresponding to the adjustable item, it indicates that there is no collision risk at this time, and there is no need to perform a subsequent interference flag state determination operation, and the adjustment request can be directly executed. By determining whether the parameters of each adjustable item included in the first seat state parameter group are within the interference range corresponding to the adjustable item, the processing efficiency can be effectively improved.

[0125] Furthermore, if the target interference flag state is the second state, the vehicle seat is adjusted based on the first seat state parameter group; wherein, when the vehicle seat is in the seat state parameter group corresponding to the second state, the leg rest will not collide with the front and rear slide rails.

[0126] When the target interference flag state is in the second state, it means that the leg rest will not collide with the front and rear slide rails, and the adjustment request can be directly executed.
