For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0032] With the rapid development of vehicle technology, vehicle configurations are becoming increasingly diverse, among which electric vehicle seats are a crucial component.

[0033] In traditional electric seats, seat adjustment is mainly triggered by the current of the seat motor to activate the anti-pinch function. However, this design is prone to errors or failures due to changes in the environment (such as temperature and voltage), which can lead to the failure of the anti-pinch function, greatly reducing the efficiency of the anti-pinch function and increasing safety risks.

[0034] In one exemplary embodiment, refer to Figure 1 The diagram shows a flowchart of a control method for adjusting a vehicle's electric seat according to an embodiment of this application. The execution body of the control method for adjusting a vehicle's electric seat is an electronic device with data processing capabilities, such as an on-board controller. The detailed description of the method is as follows: steps S101-S104: S101, in response to the adjustment command to adjust the position of the target electric seat of the vehicle, the target position parameters of the target electric seat in the target seat coordinate system are obtained, and the adjacent position parameters of the adjacent seats located in the position adjustment direction of the target electric seat in the target seat coordinate system are obtained.

[0035] In some embodiments, one of the target position parameters and adjacent position parameters includes the coordinates of the center point of the seat back pivot and the coordinates of the top point of the seat headrest; the other position parameter includes one of the coordinates of the knee point of the occupant on the seat, the coordinates of the center point of the front end of the seat cushion, and the coordinates of the center point of the front end of the seat leg rest.

[0036] Specifically, in practice, when performing step S101, the target position parameters contain different data than the adjacent position parameters.

[0037] In some embodiments, the adjustment direction refers to the direction of seat movement.

[0038] In some embodiments, to better understand the adjustment direction and position parameters in this scheme, it can be combined with Figure 2 As shown, to give a further example: (The three seats in the picture, from left to right, are the first seat, the second seat, and the third seat) First embodiment: If the target electric seat is adjusted in the direction of the rear of the vehicle and there are no occupants in the adjacent seats, the adjacent position parameters are one of the coordinates of the center point of the front end of the seat cushion and the coordinates of the center point of the front end of the seat leg rest.

[0039] Specifically, if the target electric seat is the first seat, the first seat is adjusted towards the rear of the vehicle, and there is no passenger on the second seat, then it is necessary to obtain the target position parameters of the first seat and the adjacent position parameters of the second seat. The adjacent position parameters are one of the coordinates of the center point of the front end of the seat cushion and the coordinates of the center point of the front end of the seat leg rest. The target position parameters include the coordinates of the center point of the seat back pivot and the coordinates of the top of the seat headrest.

[0040] Second embodiment: If the target electric seat is adjusted in the direction of the rear of the vehicle, and there is an occupant in the adjacent seat, the adjacent position parameter is the knee coordinate of the occupant in the seat.

[0041] Specifically, if the target electric seat is the first seat, the first seat is adjusted towards the rear of the vehicle, and there is an occupant on the second seat, then it is necessary to obtain the target position parameters of the first seat and the adjacent position parameters of the second seat. The adjacent position parameters are the knee coordinates of the occupant on the seat, and the target position parameters include the coordinates of the center point of the seat back pivot and the coordinates of the top of the seat headrest.

[0042] The third embodiment: If the target electric seat is adjusted in the direction of the vehicle's front and there are no occupants in the target electric seat, the target position parameter is one of the coordinates of the center point of the front end of the seat cushion or the coordinates of the center point of the front end of the seat leg rest.

[0043] Specifically, if the target electric seat is the second seat, the second seat is adjusted towards the front of the vehicle, and there is no passenger in the second seat, then it is necessary to obtain the target position parameters of the second seat and the adjacent position parameters of the first seat. The adjacent position parameters are one of the coordinates of the center point of the front of the seat cushion and the center point of the front of the seat leg rest. The target position parameters are one of the coordinates of the center point of the front of the seat cushion and the center point of the front of the seat leg rest.

[0044] Fourth embodiment: If the target electric seat is adjusted in the direction of the vehicle's front and there is a passenger on the target electric seat, the target position parameter is: the knee coordinates of the passenger on the seat.

[0045] Specifically, if the target electric seat is the second seat, the second seat is adjusted towards the front of the vehicle, and there is an occupant on the second seat, then it is necessary to obtain the target position parameters of the second seat and the adjacent position parameters of the first seat. The adjacent position parameters are one of the coordinates of the center point of the front end of the seat cushion and the coordinates of the center point of the front end of the seat leg rest. The target position parameter is the knee coordinates of the occupant on the seat.

[0046] S102, based on the target position parameters and adjacent position parameters, determine the first safe distance between the target electric seat and the adjacent seats.

[0047] S103, if the first safe distance is greater than the first anti-pinch safety threshold, control the motor of the target electric seat to stop adjusting.

[0048] S104, if the first safety distance is not greater than the first anti-pinch safety threshold, continue to execute the adjustment command.

[0049] In this embodiment, during the movement of the target electric seat, the target position parameters of the target electric seat and the adjacent position parameters of adjacent seats in the adjustment direction are acquired in real time. A first safe distance between the target electric seat and the adjacent seats is then calculated. As adjustment continues, the first safe distance decreases. When the first safe distance is less than a first anti-pinch safety threshold, it indicates that the target electric seat cannot continue to adjust and needs to be stopped immediately. If the first safe distance is not less than the first anti-pinch safety threshold, it indicates that there is still room for adjustment and adjustment can continue. By introducing the position parameters of adjacent seats and calculating the safe distance between them, it is determined whether to trigger the anti-pinch function. This method not only avoids anti-pinch failure caused by errors in current, voltage, and other data due to environmental factors, but also greatly improves anti-pinch efficiency and safety, further enhancing the user experience.

[0050] In some embodiments, for step S101 described above, the adjacent position parameters of adjacent seats in the target seat coordinate system located in the position adjustment direction of the target electric seat are obtained, which can be referred to... Figure 3 As shown, steps S201-S202 are included: S201, obtain the seat position parameters of adjacent seats in the first seat coordinate system.

[0051] The first seat coordinate system uses the location of the initial seat back rotation axis center point of the adjacent seats as the origin, the horizontal direction as the horizontal coordinate, and the vertical direction as the vertical coordinate.

[0052] S202, transform the seat position parameters into the target seat coordinate system to obtain the adjacent position parameters.

[0053] The target seat coordinate system refers to the coordinate system in which the target electric seat is located, that is, with the initial center point of the seat back pivot of the target electric seat as the origin, the horizontal direction as the abscissa, and the vertical direction as the ordinate.

[0054] In some embodiments, to better understand the coordinate system in this scheme, further combinations are made. Figure 2 As shown, Figure 2 The first seat in the middle, the initial center point of the seat back pivot of the seat. Origin, horizontal direction x-axis, y-axis Used as the ordinate.

[0055] Furthermore, if the first seat is the target electric seat, then the coordinate system of the first seat is the target seat coordinate system.

[0056] In some embodiments, for the above S201-S202, the following combination is continued. Figure 2 As shown, if the first seat is the target electric seat and the second seat is the adjacent seat, the seat position parameters in the coordinate system of the second seat are obtained, and then the seat position parameters are transformed to the coordinate system of the first seat to obtain the adjacent position parameters.

[0057] The coordinate transformation between different coordinate systems can be set according to the actual situation, and will not be elaborated here.

[0058] In some embodiments, in order to precisely control the power seats, the method further includes, in response to an adjustment command to adjust the position of a target power seat in the vehicle, acquiring position parameters of all power seats in the vehicle in real time.

[0059] The positional parameters include: the coordinates of the center point of the front end of the seat cushion, the coordinates of the center point of the front end of the seat leg rest, the coordinates of the center point of the seat back pivot, and the coordinates of the top of the seat headrest.

[0060] In some embodiments, the process of obtaining the position parameters of any seat in a vehicle can be referred to Figure 4 As shown, steps S301-S304 are included: S301. A second seat coordinate system is established with the initial center point of the seat back pivot as the origin, the horizontal direction as the abscissa, and the vertical direction as the ordinate.

[0061] The establishment of the second seat coordinate system can be referenced from the establishment of the first seat coordinate system, and will not be elaborated here.

[0062] S302, obtain the initial coordinates of the headrest vertex, the initial center point of the front end of the seat cushion, the initial center point of the front end of the leg rest, and the initial center point of the backrest pivot in the second seat coordinate system.

[0063] S303 obtains seat adjustment parameters in real time.

[0064] In some embodiments, the seat adjustment parameters include: seat level adjustment parameters, seat height adjustment parameters, seat back adjustment parameters, seat cushion angle adjustment parameters, and leg rest adjustment parameters.

[0065] S304, based on the seat adjustment parameters, adjusts the position parameters to obtain new position parameters.

[0066] In some embodiments, for step S302 above, the initial coordinates of the headrest apex, the initial coordinates of the front center point of the seat cushion, the initial coordinates of the front center point of the seat leg rest, and the initial coordinates of the center point of the seat back pivot are fixed.

[0067] The process of determining the initial headrest vertex coordinates described above can be found by referring to... Figure 2 As shown, and taking the second seat as an example, the details are as follows: Obtain the first distance L_back2 from the center point of the backrest pivot of the second seat to the backrest vertex, the second distance L_head2 from the backrest vertex to the highest point of the headrest, and the initial backrest angle α_back2 of the second seat; based on the first distance, the second distance, and the initial backrest angle, calculate the initial headrest vertex coordinates in the seat coordinate system where the second seat is located.

[0068] The first and second distances can be obtained from the cloud server, and the specific method of obtaining them is not limited.

[0069] The initial backrest angle can be collected by the Hall sensor of the backrest adjustment motor or obtained from the cloud server; the specific method of acquisition is not limited.

[0070] The initial coordinates of the center point of the front end of the seat cushion mentioned above can be used as a reference. Figure 2 As shown, and taking the second seat as an example, the details are as follows: Obtain the cushion length and the cushion angle between the second seat and the horizontal plane. Based on the cushion length and the cushion angle, calculate the coordinates of the initial center point of the front end of the seat cushion in the seat coordinate system where the second seat is located.

[0071] The length of the second seat cushion can be obtained from a cloud server, and the specific method of obtaining it is not limited.

[0072] The seat cushion angle can be obtained through a Hall sensor installed in the seat or from a cloud server; the specific method of acquisition is not limited.

[0073] The initial coordinates of the center point of the front end of the seat leg rest mentioned above can be referenced. Figure 2 As shown, and taking the second seat as an example, the details are as follows: Obtain the initial length of the leg rest, and based on the initial length of the leg rest and the coordinates of the center point of the front end of the initial seat cushion, calculate the coordinates of the center point of the front end of the initial seat leg rest in the seat coordinate system where the second seat is located.

[0074] The initial length of the leg support can be obtained from the cloud server, and the specific method of obtaining it is not limited.

[0075] The initial coordinates of the center point of the seat back pivot are fixed coordinates.

[0076] In some embodiments, in actual vehicles, the seats have multiple adjustment directions, such as horizontal adjustment, height adjustment, and backrest angle adjustment. Once an adjustment occurs, the seat's position parameters will also change. Therefore, in step S304 above, based on the seat adjustment parameters, the position parameters are adjusted to obtain new position parameters. See [reference needed] for details. Figure 5 As shown, steps SS401-S402 are included: S401, calculates the coordinate change based on seat adjustment parameters.

[0090] 4) Regarding the seat cushion angle adjustment parameters; Based on the seat cushion angle adjustment parameters, the change in the fourth coordinate is calculated. The seat cushion angle adjustment parameters include: the distance between the rotation center of the seat back and the origin of the second seat coordinate system, the initial angle of the seat cushion, and the adjustment angle of the seat cushion.

[0091] Specifically, because changes in the seat cushion angle cause the entire seat to rotate, this has a significant impact on other coordinate points. Therefore, the following explanations will separately illustrate the effect of the seat cushion angle on these other coordinate points, combined with... Figure 9 As shown, the specific formula for calculating the change in the fourth coordinate is as follows: The change in the x-coordinate of the center point at the front of the seat cushion after adjusting the seat cushion angle is: .

[0096] The change in the ordinate of the headrest apex after adjusting the coordinates of the center point of the seat back pivot is: .

[0097] The change in the horizontal coordinate of the headrest apex after adjusting the seat cushion angle is: .

[0098] The change in the ordinate of the headrest apex after adjusting the seat cushion angle is: .

[0099] in, Let be the distance between the center of rotation of the seat back and the origin of the second seat coordinate system. This is the initial angle of the seat cushion. Adjust the seat cushion angle.

[0100] 5) Adjustment parameters for the leg rest: Based on the leg rest adjustment parameters, the change in the fifth coordinate is calculated. These parameters include: initial leg rest length, extended leg rest length, and leg rest adjustment angle.

[0101] Specifically, in combination Figure 10 As shown, the specific formula for calculating the change in the fifth coordinate is as follows: The change in the horizontal coordinate relative to the center point of the front end of the seat cushion after adjusting the leg rest is: .

[0102] The change in the vertical coordinate relative to the center point of the front end of the seat cushion after adjusting the leg rest is: .

[0103] in, This is the initial length of the seat leg rest. This refers to the extended length of the seat leg rest. Adjust the angle of the seat leg rest.

[0104] S402, adjust the position parameters according to the coordinate change to obtain the new position parameters.

[0105] In some embodiments, after determining the amount of change according to the example in step S401 above, the position parameters can be adjusted according to the amount of change, as follows: For the vertex coordinates of the seat headrest: Based on the changes in the first, second, third, and fourth coordinates, the initial headrest vertex coordinates are adjusted to obtain the new headrest vertex coordinates.

[0106] Coordinates of the center point of the front end of the seat cushion: Based on the changes in the first, second, and fourth coordinates, the initial coordinates of the center point at the front of the seat cushion are adjusted to obtain the new coordinates of the center point at the front of the seat cushion.

[0107] Coordinates of the center point of the seat back pivot: Based on the changes in the first, second, and fourth coordinates, the initial coordinates of the center point of the seat back pivot are adjusted to obtain the new coordinates of the center point of the seat back pivot.

[0108] Coordinates of the center point of the front end of the seat cushion: Based on the change in the fifth coordinate, adjust the coordinates of the new center point of the front end of the seat cushion to obtain the coordinates of the new center point of the front end of the seat leg rest.

[0109] In this embodiment, the adjustment method described in the above embodiment is simply to add the changes to the corresponding horizontal and vertical coordinates, which will not be elaborated further here.

[0110] In some embodiments, the aforementioned change refers to the change between the new position and the initial position.

[0111] Specifically, to better understand the changes in this solution, we will take the backrest as a specific example, as follows: The initial angle of the backrest is 10°. The first adjustment is 30° towards the rear of the car, at which point the change in the backrest angle is 30° and the original backrest angle is 40°. The second adjustment is 10° towards the rear of the car, at which point the change in the backrest angle is 40°. The third adjustment is 10° towards the front of the car, at which point the change in the backrest angle is 30°.

[0112] In some embodiments, the position parameters also include the knee coordinates of the occupant in the seat.

[0113] Specifically, because the body shapes of passengers vary, resulting in different knee point coordinates, this case sets up two methods, as follows: The first method involves acquiring the knee coordinates of the occupant in real time before responding to an adjustment command that adjusts the position of the target electric seat in the vehicle, including using fixed coordinates as the knee coordinates of the occupant.

[0114] The fixed coordinates can be set according to the actual situation, and will not be elaborated here.

[0115] The second method: can be referred to Figure 11Prior to receiving an adjustment command to adjust the position of the target electric seat in the vehicle, the knee coordinates of the occupant in the seat are acquired in real time, including steps S501-S502: S501, obtain the thigh length of the seat occupant.

[0116] S502, based on thigh length, calculates the knee coordinates of the occupant in the seat.

[0117] In this embodiment, the knee coordinates of the occupant on the seat are calculated based on body parameters, including: obtaining the hip coordinates and thigh angle at the thigh; and determining the knee coordinates of the occupant in the seat coordinate system based on the hip coordinates, thigh length, and thigh angle. The thigh angle refers to the angle between the thigh surface and the horizontal plane.

[0118] Specifically, based on the thigh length and thigh angle, the horizontal and vertical distances from the knee point coordinates to the hip point coordinates on the thigh can be calculated, and thus the knee point coordinates can be determined.

[0119] Among them, the coordinates of the hip point at the thigh are fixed coordinates, which can be set according to the actual situation.

[0120] In some embodiments, for step S102 above, determining the first safe distance between the target electric seat and the adjacent seats based on the target position parameters and the adjacent position parameters includes: in the target seat coordinate system, calculating the shortest distance from one of the following parameters—the knee point coordinate of the occupant on the seat, the center point coordinate of the front end of the seat cushion, and the center point coordinate of the front end of the seat leg rest—to the straight line containing the center point coordinate of the seat back pivot and the apex coordinate of the seat headrest, and using the shortest distance as the first safe distance.

[0121] In some embodiments, during the actual adjustment of the vehicle seat, if the distance between the occupant's foot and the straight line connecting the center point of the front end of the seat cushion to the center point of the seat back pivot and the apex of the headrest is shorter than the distance between the footrest and the center point of the backrest pivot, then if the footrest adjustment is detected, the first safety distance can be increased by a fixed factor. Specific operations can be set according to actual conditions and will not be elaborated here.

[0122] In other embodiments, the position parameters also include the ankle coordinates of the occupant in the seat.

[0123] The specific acquisition methods include: obtaining the occupant's lower leg length, lower leg angle, and knee coordinates, and then determining the occupant's ankle coordinates in the seat's coordinate system. The specific calculation method can be found in the knee coordinate calculation method, and will not be elaborated upon here.

[0124] The lower leg angle can be determined based on the current angle of the footrest.

[0125] In some embodiments, the first anti-pinch safety threshold mentioned above is a fixed value, but it can also be set according to the actual situation, which will not be elaborated here.

[0126] In some embodiments, in real life, the occupants of the seat are not only adults, but may also include minors. Because the size difference between adults and minors is too large, the situation of minors must be taken into account in the actual process. Therefore, the method further includes: when the position adjustment direction of the target electric seat is the rear direction of the vehicle and there is an adjacent seat, if an occupant is detected in the adjacent seat and the occupant's body parameters do not meet the preset conditions, the first anti-pinch safety threshold is increased by a preset multiple; when the position adjustment direction of the target electric seat is the front direction of the vehicle and there is an adjacent seat, if an occupant is detected in the target electric seat and the occupant's body parameters do not meet the preset conditions, the first anti-pinch safety threshold is increased by a preset multiple.

[0127] One of the preset conditions is that the height is lower than a preset height. Other conditions can be set according to actual circumstances, which will not be elaborated upon here.

[0128] In some embodiments, in real-life situations, if the last row of seats moves, the size of the space behind it or whether anything obstructs the seats determines whether the motor should stop. Figure 12 As shown, the method further includes steps S601-S604: S601, when the position adjustment direction of the target electric seat is the rear direction of the vehicle and there are no adjacent seats, obtain the target coordinates of the target object located in the position adjustment direction of the target electric seat in the target seat coordinate system.

[0129] The target object refers to the object located behind the seat.

[0130] To better understand the scenario in this embodiment, combined with Figure 2 As shown, during the adjustment of the third seat towards the rear of the vehicle, since there is no seat at the rear, if an item is detected behind the third seat, the coordinates of the item need to be obtained to prevent the seat from crushing it. This item could be a suitcase, etc.

[0131] S602, based on the coordinates of the center point of the seat back pivot of the target electric seat, the coordinates of the top of the seat headrest, and the target coordinates, determine the second safe distance between the target electric seat and the target object.

[0132] S603, if the second safety distance is greater than the second anti-pinch safety threshold, control the motor of the target electric seat to stop adjusting.

[0133] The second anti-pinch safety threshold can be the same as or different from the first anti-pinch safety threshold, and can be set according to the actual situation.

[0134] S604, if the second safety distance is not greater than the second anti-pinch safety threshold, continue to execute the adjustment command.

[0135] In this embodiment of the disclosure, it is indicated that this setting can prevent the seat from crushing items, thereby improving the user experience.

[0136] In other embodiments, in actual vehicles, there may be situations where the seats are folded forward. Therefore, if the forward folding of the seats is detected, when calculating the first safe distance, the position parameter uses the coordinates of the headrest apex, that is, the distance between the coordinates of the folded headrest apex and the coordinates of the center point of the seat back pivot of the front seat and the coordinates of the headrest apex.

[0137] In some embodiments, in actual vehicles, the vehicle seats can also move laterally. This reduces the gap between the two seats, and the seat armrests are less rigid and easily deformed. Therefore, to protect hands or arms from being pinched by the seat armrests, the method further includes: acquiring images of the passage space between the seats in real time, and identifying whether a human structure appears in the image. If a human structure is detected in the passage space, the lateral movement of the seats is limited to a preset percentage. Here, the human structure refers to an arm or hand, etc.

[0138] The preset percentage is a fixed threshold that can be set according to the actual situation. For example, if an arm appears in the channel space, the preset percentage is 50%; if a palm appears in the middle of the channel, the preset percentage is 80%.

[0139] In this embodiment, images of the passageway space between seats can be acquired using a camera device, which can be mounted on the vehicle's armrest or roof. Specific configurations can be tailored to individual circumstances and will not be elaborated upon here.

[0140] In other embodiments, if a human structure is detected in the passageway, the vehicle's alarm system issues an alarm signal to alert the occupants to avoid injury.

[0141] In some embodiments, in actual vehicles, due to the complexity of occupants, some occupants may engage in unsafe actions, such as sticking their heads or arms out of the window. Therefore, to protect customer safety, this application may further include: acquiring an image at the window and identifying whether a human structure is present in the image; if a human structure is detected, the use of the seat adjustment function is prohibited. This design can prevent injury to occupants and improve user experience. The image at the window is acquired via a camera device, which can be positioned on one side of the vehicle window; the specific location can be determined according to actual conditions.

[0142] In some embodiments, in actual vehicles, due to the complexity of occupants, some occupants may put their feet under the seat, which may compress their bodies when adjusting the seat. Therefore, in order to protect the safety of occupants, this application also includes: acquiring a bottom image, and if a human body structure is detected in the bottom image, then the use of the seat adjustment function is prohibited.

[0143] In some embodiments, in actual vehicles, due to the complexity of occupants, some occupants may scream after being pinched by the seat. Therefore, the method may further include: real-time acquisition of in-vehicle sound data; if the sound data meets preset conditions, the anti-pinch function is immediately triggered, and the power-adjustable seat is activated. This setup can protect occupant safety and improve user experience.

[0144] The preset conditions can be preset voice data, such as a passenger shouting "Stop!" or other voice data, which can be set according to the actual situation.

[0145] In other embodiments, the preset condition can be that the volume of the sound data exceeds a safe threshold.

[0146] In some embodiments, to protect the safety of the occupants, the method further includes: during the adjustment of the target electric seat, if a preset button is detected to be triggered, controlling the motor of the target electric seat to stop working.

[0147] The preset buttons can be any button on the seat armrest. The specific design location can be set according to the actual situation.

[0148] In some embodiments, to improve occupant safety, the method may further include: acquiring the motor operating current of the target electric seat in real time, and controlling the motor to stop working if the motor operating current is greater than the safe current.

[0149] In this application, in response to an adjustment command to adjust the position of a target electric seat in a vehicle, the target position parameters of the target electric seat in the target seat coordinate system are obtained, and the adjacent position parameters of adjacent seats located in the position adjustment direction of the target electric seat in the target seat coordinate system are also obtained. Based on the target position parameters and the adjacent position parameters, a first safe distance between the target electric seat and the adjacent seats is determined. If the first safe distance is greater than a first anti-pinch safety threshold, the motor of the target electric seat is controlled to stop adjusting; if the first safe distance is not greater than the first anti-pinch safety threshold, the adjustment command continues to be executed. By introducing the position parameters of adjacent seats through the technical solution provided in this application, and calculating the safe distance between adjacent seats to determine whether to trigger the anti-pinch function, this method not only avoids anti-pinch failure caused by errors in current, voltage, and other data due to environmental factors, but also greatly improves anti-pinch efficiency and safety, further enhancing the user experience.

The determining unit 702 is used to determine a first safe distance between the target electric seat and the adjacent seats based on the target position parameters and the adjacent position parameters; Control unit 703 is used to control the motor of the target electric seat to stop adjusting if the first safety distance is greater than the first anti-pinch safety threshold. The execution unit 704 is used to continue executing the adjustment command if the first safety distance is not greater than the first anti-pinch safety threshold.

[0152] In an exemplary embodiment, based on the above embodiments, the vehicle electric seat adjustment control device 700 is used to obtain the adjacent position parameters of adjacent seats in the target seat coordinate system in the position adjustment direction of the target electric seat, specifically for: Obtain the seat position parameters of adjacent seats in the first seat coordinate system; Transform the seat position parameters into the target seat coordinate system to obtain the adjacent position parameters; The first seat coordinate system uses the location of the initial seat back rotation axis center point of the adjacent seats as the origin, the horizontal direction as the horizontal coordinate, and the vertical direction as the vertical coordinate.

[0154] In an exemplary embodiment, based on the above embodiment, if the target electric seat is adjusted in the direction of the rear of the vehicle and there are no occupants in the adjacent seats, the adjacent position parameters are one of the coordinates of the center point of the front end of the seat cushion and the coordinates of the center point of the front end of the seat leg rest. If the target electric seat is adjusted towards the rear of the vehicle, and there is an occupant in the adjacent seat, the adjacent position parameter is the knee coordinate of the occupant in the seat. If the target electric seat is adjusted in the direction of the vehicle's front and there are no occupants in the target electric seat, the target position parameter is one of the coordinates of the center point of the front end of the seat cushion or the center point of the front end of the seat leg rest.

[0156] In an exemplary embodiment, based on the above embodiment, the vehicle electric seat adjustment control device 700 is further configured to: acquire position parameters of all electric seats in the vehicle in real time before responding to the adjustment command for adjusting the position of the target electric seat in the vehicle; The positional parameters include: the coordinates of the center point of the front end of the seat cushion, the coordinates of the center point of the front end of the seat leg rest, the coordinates of the center point of the seat back pivot, and the coordinates of the top of the seat headrest.

[0157] In an exemplary embodiment, based on the above embodiments, the process by which the vehicle electric seat adjustment control device 700 obtains the seat position parameters for any seat in the vehicle is as follows: A second seat coordinate system is established with the initial center point of the seat back pivot as the origin, the horizontal direction as the abscissa, and the vertical direction as the ordinate. In the second seat coordinate system, obtain the initial coordinates of the headrest vertex, the front center point of the seat cushion, the front center point of the leg rest, and the center point of the backrest pivot. The system acquires the seat adjustment parameters in real time, including: seat level adjustment parameters, seat height adjustment parameters, seat back adjustment parameters, seat cushion angle adjustment parameters, and leg rest adjustment parameters. Based on the seat adjustment parameters, the position parameters are adjusted to obtain new position parameters.

[0159] In an exemplary embodiment, based on the above embodiments, the vehicle electric seat adjustment control device 700 is used to adjust the position parameters based on the seat adjustment parameters to obtain new position parameters, specifically for: Based on the seat leveling adjustment parameters, the change in the first coordinate is calculated; The change in the second coordinate is calculated based on the seat height adjustment parameters; The change in the third coordinate is calculated based on the seat back adjustment parameters; The change in the fourth coordinate is calculated based on the seat angle adjustment parameters; Based on the leg support adjustment parameters, the change in the fifth coordinate is calculated; Based on the changes in the first, second, third, and fourth coordinates, the initial headrest vertex coordinates are adjusted to obtain the new headrest vertex coordinates.

Based on the changes in the first, second, and fourth coordinates, the initial coordinates of the center point of the seat back pivot are adjusted to obtain the new coordinates of the center point of the seat back pivot. Based on the change in the fifth coordinate, adjust the coordinates of the new center point of the front end of the seat cushion to obtain the coordinates of the new center point of the front end of the seat leg rest.

[0160] In one exemplary embodiment, based on the above embodiments, the position parameters further include the knee coordinates of the occupant in the seat.

[0161] In an exemplary embodiment, based on the above embodiments, the vehicle electric seat adjustment control device 700 is used to acquire the knee coordinates of the occupant in real time before responding to the adjustment command for adjusting the position of the target electric seat of the vehicle, specifically for: The fixed coordinates are used as the knee coordinates of the occupant in the seat.

[0162] In one exemplary embodiment, based on the above embodiments, the position parameters further include the knee coordinates of the occupant in the seat.

[0164] In an exemplary embodiment, based on the above embodiment, when the target electric seat is adjusted in the direction of the rear of the vehicle and there is an adjacent seat, if an occupant is detected in the adjacent seat and the occupant's body parameters do not meet the preset conditions, the first anti-pinch safety threshold is increased by a preset multiple. When the target electric seat is adjusted in the direction of the vehicle's front and there is an adjacent seat, if an occupant is detected on the target electric seat and the occupant's body parameters do not meet the preset conditions, the first anti-pinch safety threshold will be increased by a preset multiple.

[0165] In one exemplary embodiment, based on the above embodiments, the vehicle electric seat adjustment control device 700 is further configured to: When the target electric seat is adjusted in the direction of the rear of the vehicle and there are no adjacent seats, obtain the target coordinates of the target object in the target seat coordinate system in the direction of the target electric seat's adjustment. Based on the coordinates of the center point of the seat back pivot of the target electric seat, the coordinates of the top point of the seat headrest, and the target coordinates, the second safe distance between the target electric seat and the target object is determined.

By introducing the position parameters of adjacent seats through the technical solution provided in this application, and calculating the safe distance between adjacent seats to determine whether to trigger the anti-pinch function, this method not only avoids anti-pinch failure caused by errors in current, voltage, and other data due to environmental factors, but also greatly improves anti-pinch efficiency and safety, further enhancing the user experience.
