Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a method and device for identifying interference with a vehicle seat back. Background Art

[0002] With the development of vehicle technology, a technology for adjusting the backrest of car seats has emerged. Users can adjust the angle of the car seat backrest to obtain a better riding experience, thereby reducing user fatigue during long-term car riding. In the process of adjusting the car seat backrest angle, seat back interference may also occur. For example, if the backrest angle of the front seat of the car is too backward, or the backrest angle of the rear seat is too forward, seat back interference may occur, resulting in abnormalities.

[0003] In order to avoid the above-mentioned abnormalities, it is necessary to identify the phenomenon of mutual interference of car seat backs. Currently, this phenomenon is usually identified by identifying the angle of the front and rear seats, and then judging whether the seat backs interfere with each other based on the angle. However, this method of identifying interference of car seat backs has a low accuracy rate. Summary of the invention

[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] In one embodiment, Figure 1 As shown, a method for identifying interference of a car seat back is provided. This embodiment uses the method to be applied to a controller for controlling a car seat back as an example. In this embodiment, the method includes the following steps:

[0038] Step S101, in response to a backrest adjustment operation for a first car seat, obtain a first backrest angle of the first car seat and a second backrest angle of a second car seat associated with the first car seat; the second car seat is a car seat that may have a seat back interference phenomenon with the first car seat during the backrest adjustment process of the first car seat.

[0039] Among them, the backrest adjustment operation refers to the operation initiated by the user for adjusting the backrest angle of the car seat, and the first car seat refers to the car seat corresponding to the backrest adjustment operation initiated by the user, and the second car seat is the car seat in which the seat back interference phenomenon may occur during the adjustment of the first car seat, for example, it can be a car seat located in front of the first car seat, or it can be a car seat located behind the first car seat. For example, the car contains seat A, seat B and seat C, wherein seat A is located in front of seat B, and seat B is located in front of seat C. When the backrest adjustment operation is performed on seat A, the seat back interference phenomenon may occur on seat B. In this case, seat A can be used as the first car seat, and seat B can be used as the second car seat. Similarly, if the backrest adjustment operation is performed on seat B, the seat back interference phenomenon may occur on seat A and seat C. In this case, seat A can be used as the first car seat, and seat B can be used as the second car seat. Similarly, if the backrest adjustment operation is performed on seat B, the seat back interference phenomenon may occur on seat A and seat C. In this case, seat A and seat C can be used as the second car seat.

[0040] The first backrest angle refers to the current backrest angle of the first car seat, and the second backrest angle refers to the current backrest angle of the second car seat. The backrest angle may refer to the angle between the car seat backrest and the horizontal forward direction of the car. Specifically, when the user initiates a backrest adjustment operation for the first car seat, the controller may respond to the operation, thereby identifying the second car seat having a seat back interference phenomenon with the first car seat, and obtaining the backrest angles of the first car seat and the second car seat as the first backrest angle and the second backrest angle, respectively.

[0041] Step S102, when the first backrest angle and the second backrest angle meet the preset angle condition, obtaining the first reference position coordinates and the seat reference line length associated with the target car seat, and obtaining the second reference position coordinates of the associated car seat; the target car seat is one of the first car seat and the second car seat, and the associated car seat is one of the first car seat and the second car seat other than the target car seat;

[0042] Step S103, obtaining a seat back interference phenomenon recognition result of the first vehicle seat and the second vehicle seat according to the first backrest angle, the second backrest angle, the first reference position coordinates, the second reference position coordinates and the seat reference line length.

[0043] The target car seat refers to the car seat for which the seat reference line length needs to be obtained. The target car seat can be one of the first car seat or the second car seat, and the associated car seat refers to the other of the first car seat and the second car seat except the target car seat. For example, seat A and seat B are respectively the first car seat and the second car seat. If seat A is identified as the target car seat, then seat B is the associated car seat. Similarly, if seat B is identified as the target car seat, then seat A is the associated car seat. The first reference position coordinate is the coordinate information of the reference position associated with the target car seat, and the second reference position coordinate is the coordinate information of the reference position associated with the associated car seat. The seat reference line length refers to the distance between the reference position associated with the target car seat and a predetermined position of the target car seat. The predetermined position can be the contact point between the target car seat and the associated car seat when the seat back interference occurs between the target car seat and the associated car seat.

[0044] In this embodiment, in the process of identifying the seat back interference phenomenon, if the first backrest angle and the second backrest angle meet the preset angle conditions, it is necessary to combine the backrest angle of the car seat, the reference position coordinates of the car seat, and the seat reference line length of the target car seat to identify whether there is a seat back interference phenomenon between the first car seat and the second car seat. The controller can first identify the target car seat and the associated car seat from the first car seat and the second car seat, and can also obtain the reference position coordinates and seat reference line length of the target car seat, as well as the reference position coordinates of the associated car seat. Afterwards, the seat back interference phenomenon identification result between the first car seat and the second car seat can be obtained based on the collected first backrest angle and second backrest angle, the reference position coordinates and seat reference line length of the target car seat, and the reference position coordinates of the associated car seat.

[0045] In the above-mentioned car seat back interference identification method, by responding to the backrest adjustment operation for the first car seat, the first backrest angle of the first car seat and the second backrest angle of the second car seat associated with the first car seat are obtained; the second car seat is a car seat that may have a seat back interference phenomenon with the first car seat during the backrest adjustment process of the first car seat; when the first backrest angle and the second backrest angle meet the preset angle conditions, the first reference position coordinates and the seat reference line length associated with the target car seat are obtained, and the second reference position coordinates of the associated car seat are obtained; the target car seat is one of the first car seat and the second car seat, and the associated car seat is one of the first car seat and the second car seat other than the target car seat; based on the first backrest angle, the second backrest angle, the first reference position coordinates, the second reference position coordinates and the seat reference line length, the seat back interference phenomenon identification result of the first car seat and the second car seat is obtained. The present application can obtain a first backrest angle of the first car seat and a second backrest angle of the second car seat which may have a seat back interference phenomenon with the first car seat when the backrest adjustment operation is performed on the first car seat. Therefore, when both the first backrest angle and the second backrest angle meet the preset angle conditions, a target car seat and an associated car seat can be screened out from the first car seat and the second car seat, and the first reference position coordinates and the seat reference line length associated with the target car seat, as well as the second reference position coordinates of the associated car seat can be obtained. Therefore, the first backrest angle, the second backrest angle, the first reference position coordinates, the second reference position coordinates and the seat reference line length can be combined to identify whether there is a seat back interference phenomenon between the first car seat and the second car seat. Compared with only using the seat back angle to determine whether there is a seat back interference phenomenon, the present application can improve the accuracy of identifying car seat back interference.

[0046] In one embodiment, Figure 2 As shown, step S102 may further include:

[0047] Step S201, when the first backrest angle and the second backrest angle meet the preset angle condition, obtain the target car seat and the associated car seat from the first car seat and the second car seat according to the spatial position relationship between the first car seat and the second car seat.

[0048] The spatial position relationship may refer to the relative spatial position relationship between the first car seat and the second car seat. In this embodiment, the controller may identify the first car seat and the second car seat based on the relative spatial positions of the first car seat and the second car seat when the first backrest angle and the second backrest angle meet the preset angle conditions.

[0049] Step S202, obtaining the coordinates of a first reference point preset in the target car seat as the first reference position coordinates, and obtaining the coordinates of a second reference point preset in the associated car seat as the second reference position coordinates.

[0050] The first reference point refers to the seat reference point set in the target car seat, the second reference point refers to the seat reference point set in the associated car seat, the first reference position coordinate refers to the position coordinate corresponding to the first reference point, and the second reference position coordinate refers to the position coordinate corresponding to the second reference point, and the above position coordinates can be pre-set. Specifically, the controller can pre-store the position coordinates of the reference points corresponding to each car seat, and after identifying the target car seat and the associated car seat, the first reference position coordinate and the second reference position coordinate can be obtained from the above position coordinates.

[0051] Step S203, obtaining the distance between a preset first reference point and a backrest contact point in the target car seat as the seat reference line length; the backrest contact point is obtained by performing motion verification and identification on the first car seat and the second car seat.

[0052] The backrest contact point refers to the contact point between the seat backs obtained by performing motion calibration and identification on the first car seat and the second car seat. The motion calibration can be achieved by changing the backrest angles of the first car seat and the second car seat. The seat reference line length refers to the distance between the first reference point and the backrest contact point in the target car seat. The distance can also be set in advance. For example, it can be obtained based on the distance between the backrest contact point and the reference point after the backrest contact point of the car seat is identified through motion calibration.

[0053] Taking the first car seat as seat A and the second car seat as seat B as an example, when performing motion verification on seats A and B, the backrest contact points of seats A and B can be identified respectively, namely contact point A and contact point B, wherein seat A is provided with reference point A and seat B is provided with reference point B, and then the controller can respectively obtain the distance between contact point A and reference point A as reference line length A, and the distance between contact point B and reference point B as reference line length B. Afterwards, after identifying the target car seat, if seat A is the target car seat, then reference line length A is used as the seat reference line length, and similarly, if seat B is the target car seat, then reference line length B is used as the seat reference line length.

[0054] In this embodiment, the first reference position coordinates, the second reference position coordinates and the seat reference line length can be pre-set. When the first backrest angle and the second backrest angle meet the preset angle conditions, the target car seat and the associated car seat can be obtained based on the spatial position relationship. Thereafter, the first reference position coordinates, the second reference position coordinates and the seat reference line length can be obtained based on the pre-set reference position coordinates and seat reference line lengths of each car seat. The seat reference line length can be obtained by performing motion verification and identification on the first car seat and the second car seat to obtain the backrest contact point. In this way, the efficiency and accuracy of data acquisition can be improved.

[0055] Furthermore, if Figure 3 As shown, before step S202, the following steps may also be included:

[0056] Step S301, setting the coordinates of the position of the first seat back adjustment structure contained in the target car seat as the first reference position coordinates, and setting the coordinates of the position of the second seat back adjustment structure contained in the associated car seat as the second reference position coordinates.

[0057] The first seat back adjustment structure refers to the seat back adjustment structure included in the target car seat, and the second seat back adjustment structure refers to the seat back adjustment structure included in the associated car seat, wherein the seat back adjustment structure is an adjustment structure for the backrest angle of the car seat. In this embodiment, the controller can use the seat back adjustment structure of the car seat as a reference point for the car seat, that is, the first seat back adjustment structure is the first reference point, and the second seat back adjustment structure is the second reference point. Therefore, the controller can set the coordinates of the position of the first seat back adjustment structure as the first reference position coordinates, and set the coordinates of the position of the second seat back adjustment structure as the second reference position coordinates.

[0058] Before step S203, the following steps may also be included:

[0059] Step S302, performing motion verification on the first automobile seat and the second automobile seat, and obtaining a backrest contact point between the first automobile seat and the second automobile seat when a seat back interference phenomenon occurs between the first automobile seat and the second automobile seat;

[0060] Step S303, setting the distance between the backrest contact point in the first car seat and the position of the first backrest adjustment structure as the seat reference line length associated with the first car seat, and setting the distance between the backrest contact point in the second car seat and the position of the second backrest adjustment structure as the seat reference line length associated with the second car seat.

[0061] The seat reference line length can be obtained in the following way: first, the first car seat and the second car seat are motion-calibrated. The motion calibration method can be to change the backrest angles of the first car seat and the second car seat until the backrests of the first car seat and the second car seat interfere with each other. At this time, the backrest of the first car seat will contact the backrest of the second car seat, and the controller can obtain the backrest contact point of the first car seat and the second car seat.

[0062] Afterwards, the controller can set the distance between the backrest contact point in the first car seat and the position of the first seat back adjustment structure as the seat reference line length associated with the first car seat, and set the distance between the backrest contact point in the second car seat and the position of the second seat back adjustment structure as the seat reference line length associated with the second car seat. In this way, the seat reference line lengths associated with the first car seat and the second car seat can be obtained respectively, and then after the target car seat is identified from the first car seat and the second car seat, the seat reference line length associated with the target car seat can be obtained by using the above seat reference line length.

[0063] In this embodiment, the coordinates of the position of the seat back adjustment structure can also be set as the reference position coordinates, and after the backrest contact point is identified through motion verification, the distance between the backrest contact point and the position of the corresponding first seat back adjustment structure is used as the seat reference line length associated with the seat. In this way, the accuracy of obtaining the reference position coordinates and the seat reference line length can be improved.

[0064] In one embodiment, the preset angle condition includes: a first preset angle condition and a second preset angle condition; the spatial position relationship includes a front and rear position relationship; step S201 may further include: when the first backrest angle and the second backrest angle meet the first preset angle condition, the car seat located in front of the first car seat and the second car seat is used as the target car seat, and the car seat located behind the first car seat and the second car seat is used as the associated car seat; when the first backrest angle and the second backrest angle meet the second preset angle condition, the car seat located behind the first car seat and the second car seat is used as the target car seat, and the car seat located in front of the first car seat and the second car seat is used as the associated car seat.

[0065] In this embodiment, the preset angle condition may be composed of two parts, namely, a first preset angle condition and a second preset angle condition. As long as the first backrest angle and the second backrest angle meet one of the first preset angle condition or the second preset angle condition, the first backrest angle and the second backrest angle meet the preset angle condition. The spatial position relationship includes a front-to-back position relationship, which can represent the front-to-back position between the first car seat and the second car seat.

[0066] At the same time, corresponding to different preset angle conditions, the controller obtains the target car seat and the associated car seat in different ways. For example, if the first backrest angle and the second backrest angle meet the first preset angle condition, the controller can use the car seat located in the front of the first car seat and the second car seat as the target car seat, and the car seat located in the back is used as the associated car seat. Similarly, if the first backrest angle and the second backrest angle meet the second preset angle condition, the controller can use the car seat located in the back of the first car seat and the second car seat as the target car seat, and the car seat located in the front is used as the associated car seat.

[0067] In this embodiment, the preset angle conditions include: a first preset angle condition and a second preset angle condition, and the spatial position relationship includes a front and rear position relationship. In addition, the target car seat and the associated car seat can be identified according to the front and rear relationship of the first car seat and the second car seat based on whether the first backrest angle and the second backrest angle satisfy the first preset angle condition or the second preset angle condition. In this way, the accuracy of identifying the target car seat and the associated car seat can be improved.

[0068] Furthermore, before step S201, it may also include: according to the spatial position relationship, obtaining the front seat of the car located in the front, and the rear seat of the car located in the rear from the first car seat and the second car seat; when the front seat backrest angle corresponding to the front seat of the car is greater than the preset front seat backrest angle threshold, and the rear seat backrest angle corresponding to the rear seat of the car is greater than the preset rear seat backrest angle threshold, determining that the first backrest angle and the second backrest angle meet the first preset angle condition; the preset front seat backrest angle threshold and the preset rear seat backrest angle threshold are obtained by performing motion verification on the first car seat and the second car seat; when the front seat backrest angle is less than the preset front seat backrest angle threshold, and the rear seat backrest angle is greater than the preset rear seat backrest angle threshold, determining that the first backrest angle and the second backrest angle meet the second preset angle condition.

[0069] Among them, the front car seat refers to the seat located in the front between the first car seat and the second car seat, and the rear car seat refers to the seat located in the rear between the first car seat and the second car seat. In this embodiment, the controller can first identify the front car seat and the rear car seat between the first car seat and the second car seat based on the spatial position relationship between the first car seat and the second car seat.

[0070] The front seat back angle refers to the seat back angle of the front seat of the car, and the rear seat back angle refers to the seat back angle of the rear seat of the car. Since the controller has obtained the first back angle and the second back angle, after identifying the front seat and the rear seat of the first car seat and the second car seat, the front seat back angle and the rear seat back angle can also be identified from the first back angle and the second back angle. For example, if the first car seat is the front seat of the car, the first back angle is used as the front seat back angle, and the second back angle is used as the rear seat back angle. If the second car seat is the front seat of the car, the second back angle is used as the front seat back angle, and the first back angle is used as the rear seat back angle.

[0071] The preset front seat back angle threshold is a preset front seat back angle threshold, and the preset rear seat back angle threshold is a preset rear seat back angle threshold. The above thresholds are used to determine whether the first back angle and the second back angle meet the preset conditions. The thresholds can also be preset by performing motion verification on the first vehicle seat and the second vehicle seat. If the front seat back angle is greater than the preset front seat back angle threshold, and the rear seat back angle is also greater than the preset rear seat back angle threshold, it is determined that the first back angle and the second back angle meet the first preset angle condition, and if the front seat back angle is less than the preset front seat back angle threshold, and the rear seat back angle is also less than the preset rear seat back angle threshold, it is determined that the first back angle and the second back angle meet the second preset angle condition.

[0072] In this embodiment, the front seat back angle threshold and the rear seat back angle threshold can also be set by pre-motion calibration of the first car seat and the second car seat, so that the relationship between the front seat back angle and the preset front seat back angle threshold, as well as the relationship between the rear seat back angle and the preset rear seat back angle threshold can be judged according to the front-to-back relationship between the first car seat and the second car seat, and then it can be identified whether the preset angle condition is met, and whether the first preset angle condition or the second preset angle condition is met. In this way, the efficiency of angle condition recognition can be improved.

[0073] Furthermore, the preset front seat back angle threshold and the preset rear seat back angle threshold are set by the following process: motion verification is performed on the front seat and the rear seat of the automobile, and the front seat back angle corresponding to the front seat of the automobile and the rear seat back angle corresponding to the rear seat of the automobile are obtained when a seat back interference occurs between the front seat and the rear seat of the automobile; the front seat back angle is set to the preset front seat back angle threshold, and the rear seat back angle is set to the preset rear seat back angle threshold.

[0074] In this embodiment, the preset front seat back angle threshold can be the seat back angle corresponding to the front seat of the car when seat back interference occurs between the front seat and the rear seat of the car during the motion verification of the front seat and the rear seat of the car, while the preset rear seat back angle threshold is the seat back angle corresponding to the rear seat of the car when seat back interference occurs.

[0075] Specifically, when the present application performs motion verification on the first car seat and the second car seat, it can also identify the front car seat and the rear car seat according to the front and rear position relationship of the first car seat and the second car seat. Then, when the seat backs of the front car seat and the rear car seat interfere with each other, the front seat back angle of the front car seat and the rear seat back angle of the rear car seat are collected as the preset front seat back angle threshold and the preset rear seat back angle threshold, respectively.

[0076] In this embodiment, the controller can also use the front seat back angle when the front seat and the rear seat of the car interfere with each other as the preset front seat back angle threshold, and use the rear seat back angle as the preset rear seat back angle threshold when performing motion verification on the front seat and the rear seat of the car. In this way, the accuracy of the setting of the front seat back angle threshold and the rear seat back angle threshold can be improved.

[0077] In addition, after obtaining the front seat located in front and the rear seat located in the rear from the first car seat and the second car seat, it can also include: when the front seat back angle is greater than a preset front seat back angle threshold, and the rear seat back angle is less than a preset rear seat back angle threshold, determining that there is a seat back interference phenomenon between the first car seat and the second car seat; when the front seat back angle is less than the preset front seat back angle threshold, and the rear seat back angle is greater than the preset rear seat back angle threshold, determining that there is no seat back interference phenomenon between the first car seat and the second car seat.

[0078] If the front seat back angle is greater than the preset front seat back angle threshold, and the rear seat back angle is less than the preset rear seat back angle threshold, it means that the front seat reclining angle of the car is larger than the front seat reclining angle when the seat back interference phenomenon occurs, and the rear seat forward tilting angle of the car is smaller than the rear seat forward tilting angle when the seat back interference phenomenon occurs. In this case, seat back interference phenomenon will inevitably occur, so the controller can directly identify that seat back interference phenomenon will occur in this case.

[0079] Similarly, if the front seat back angle is less than the preset front seat back angle threshold, and the rear seat back angle is greater than the preset rear seat back angle threshold, it means that the front seat reclining angle of the car is smaller than the front seat reclining angle when seat back interference occurs, and the rear seat forward tilting angle of the car is larger than the rear seat forward tilting angle when seat back interference occurs. In this case, seat back interference will definitely not occur, so the controller can directly recognize that seat back interference will not occur in this case.

[0080] If the first backrest angle and the second backrest angle do not meet the preset angle conditions, the controller can directly identify whether seat back interference will occur based on the relationship between the front seat back angle and the preset front seat back angle threshold, and based on the relationship between the rear seat back angle and the preset rear seat back angle threshold. In this way, the integrity of the seat back interference phenomenon identification can be ensured.

[0081] In one embodiment, the first reference position coordinates are the coordinates of the position of the first seat back adjustment structure included in the target car seat, the second reference position coordinates are the coordinates of the position of the second seat back adjustment structure included in the associated car seat, and the seat reference line length is the distance between the backrest contact point in the target car seat and the position of the first seat back adjustment structure; Figure 4 As shown, step S103 may further include:

[0082] Step S401, acquiring a target backrest angle of a target vehicle seat and an associated backrest angle of an associated vehicle seat from the first backrest angle and the second backrest angle.

[0083] Among them, the target backrest angle refers to the seat backrest angle of the target car seat, and the associated backrest angle refers to the seat backrest angle of the associated car seat. Since the target car seat and the associated car seat are composed of a first car seat and a second car seat, after the controller identifies the target car seat and the associated car seat from the first car seat and the second car seat, it can further identify the target backrest angle and the associated backrest angle from the first backrest angle and the second backrest angle.

[0084] Step S402, obtaining the contact point position coordinates of the backrest contact point in the target automobile seat according to the first reference position coordinates, the target backrest angle and the seat reference line length.

[0085] Among them, the first reference position coordinate refers to the coordinate of the position of the first seat back adjustment structure contained in the target car seat, and the seat reference line length refers to the distance between the backrest contact point in the target car seat and the position of the first seat back adjustment structure. Therefore, after obtaining the coordinates of the position of the first seat back adjustment structure, the target backrest angle and the seat reference line length, the controller can uniquely determine the position coordinates of the backrest contact point in the target car seat, that is, determine the contact point position coordinates.

[0086] For example, the contact point position coordinates can be expressed as (x1, z1), then the contact point position coordinates can be calculated by the following formula:

[0087]

[0088]

[0089] Among them, the first reference position coordinates are (a, b), the seat reference line length is c, and the target backrest angle is .

[0090] Step S403, constructing a coordinate expression of a backrest reference line associated with the vehicle seat according to the associated backrest angle and the second reference position coordinates.

[0091] The backrest reference line refers to the line between the contact point of the associated vehicle seat and the second backrest adjustment structure included in the associated vehicle seat. Since the second reference position coordinates can represent the coordinates of the position of the second backrest adjustment structure included in the associated vehicle seat, and the associated backrest angle can represent the angle of the line between the contact point of the associated vehicle seat and the associated vehicle seat, the expression of the backrest reference line of the associated vehicle seat can be constructed based on the associated backrest angle and the second reference position coordinates as the coordinate expression of the backrest reference line.

[0092] For example, the expression relating the backrest reference line of a car seat can be expressed as follows:

[0093]

[0094] Among them, (x, z) represents the different coordinate points contained in the backrest reference line, the second reference position coordinate is (d, e), and the associated backrest angle is .

[0095] Step S404, obtaining the distance between the backrest contact point and the backrest reference line according to the contact point position coordinates and the coordinate expression form, and obtaining the seat backrest interference phenomenon recognition result according to the distance between the backrest contact point and the backrest reference line.

[0096] In this embodiment, the method for determining whether there is seat back interference is to calculate the distance between the back contact point in the target car seat and the back reference line of the associated car seat. The distance is calculated by combining the contact point position coordinates and the expression of the back reference line.

[0097] For example, the distance between the backrest contact point in the target car seat and the backrest reference line of the associated car seat can be represented by D1, which can be calculated by the following formula:

[0098]

[0099] Afterwards, the controller can further obtain the seat back interference phenomenon identification result based on the distance between the backrest contact point and the backrest reference line.

[0100] In this embodiment, the contact point position coordinates of the backrest contact point in the target car seat can be obtained according to the first reference position coordinates of the target car seat, the target backrest angle and the seat reference line length. The coordinate expression of the backrest reference line of the associated car seat can also be constructed according to the associated backrest angle and the second reference position coordinates of the associated car seat. The distance between the backrest contact point and the backrest reference line can be obtained by using the contact point position coordinates and the coordinate expression, and then the seat back interference phenomenon can be identified by using the distance. In this way, the accuracy of identifying the seat back interference phenomenon can be improved.

[0101] Furthermore, step S404 may further include: when the distance between the backrest contact point and the backrest reference line is less than a preset distance threshold, determining that there is a seat back interference phenomenon between the first car seat and the second car seat; when the distance between the backrest contact point and the backrest reference line is greater than or equal to the distance threshold, determining that there is no seat back interference phenomenon between the first car seat and the second car seat.

[0102] The preset distance threshold is a pre-set threshold used to determine whether there is a seat back interference phenomenon. For example, the threshold can be set to 10mm. The threshold can be used to eliminate the error caused by the calculation to further improve the accuracy of the seat back interference phenomenon identification. Specifically, if the distance between the backrest contact point and the backrest reference line is less than the preset distance threshold, it means that the backrest contact point of the target car seat is very close to the backrest reference line of the associated car seat. At this time, it is very likely that the seat back interference phenomenon will occur. In this case, the controller will determine that there is a seat back interference phenomenon between the first car seat and the second car seat. Similarly, if the distance between the backrest contact point and the backrest reference line is greater than or equal to the preset distance threshold, it means that the backrest contact point of the target car seat is still at a certain distance from the backrest reference line of the associated car seat. At this time, it means that there is no seat back interference phenomenon between the first car seat and the second car seat.

[0103] In this embodiment, the controller can identify the existence of seat back interference between the first car seat and the second car seat by comparing the distance between the backrest contact point and the backrest reference line with the preset distance threshold. Since the preset distance threshold can be used to eliminate errors caused by calculation, this method can further improve the accuracy of identifying seat back interference.

[0104] In one embodiment, a seat back adjustment interference determination method is also provided. The method can detect the relative position relationship between the front and rear seats in real time. Compared with directly determining whether the seat backs interfere with each other by identifying the angle interval range of the front and rear seats, this embodiment can improve the accuracy of identifying the seat back interference phenomenon. This can be achieved through the following principles:

[0105] (1) The positions A and B of the first contact points of the front and rear seats during the adjustment of the front and rear seat back angles are obtained through motion calibration.

[0106] (2) When the backrest angle changes, calculate the distance between contact point A and the rear seat, and the distance between contact point B and the front seat, and determine the relative position relationship between the front and rear seats.

[0107] The specific implementation process is as follows:

[0108] The coordinate values ​​are taken based on the XZ axis plane. The Y axis coordinates are the same by default, and no description or calculation related to the Y axis coordinates is performed.

[0109] For the front seats, Figure 5As shown, in the XZ-axis plane, the coordinates of the reference point Q1 are (a, b), and the coordinates of the contact point A are (x1, z1), where the coordinates of the reference point remain unchanged during the backrest angle adjustment process. For example, the position of the backrest adjustment structure of the front seat can be used as the reference point Q1. The reference line R1 represents the line from point A to the reference point Q1, and the distance of the reference line R1 is c, which is a constant. The front seat backrest angle It represents the positive angle of R1 with respect to the X-axis, which is related to the adjustment angle of the backrest adjustment operation.

[0110] For the rear seats, Figure 6 As shown, in the XZ-axis plane, the coordinates of the reference point Q2 are (d, e), and the coordinates of the contact point B are (x2, z2), where the coordinates of the reference point remain unchanged during the backrest angle adjustment process. For example, the position of the backrest adjustment structure of the rear seat can be used as the reference point Q2. The reference line R2 represents the line from point B to the reference point Q2, and the distance of the reference line R2 is f, which is a constant. The backrest angle of the rear seat It represents the positive angle of R2 with respect to the X-axis, which is related to the adjustment angle of the backrest adjustment operation.

[0111] The results of motion verification can be shown as Figure 7 As shown, when the seat backs interfere, the first contact points of the front and rear seats are A and B, and when point A and point B contact and interfere, the angle of the front seat is , the rear seat angle is .

[0112] Therefore, during the change of the backrest angle, the following process can be used to determine whether there is seat back interference:

[0113] (1) When and By calculating the distance D1 between point A and the rear seat joining line R2, the relative position of the front and rear seats can be determined, that is, the distance between point (x1, z1) and the straight line Distance:

[0114]

[0115]

[0116]

[0117] (2) When and , by calculating the distance D2 between point B and the front seat reference line R1, the relative position of the front and rear seats is determined, that is, the distance between point (x2, z2) and the straight line Distance:

[0118]

[0119]

[0120]

[0121] In the above cases, when D1 or D2 is less than 10 mm, it is determined that the front and rear seats interfere with each other.

[0122] (3) When and , directly determine the interference between the front and rear seats.

[0123] (4) When and , directly determine that the front and rear seats do not interfere.

[0124] Through this embodiment, during the adjustment of the front and rear seat backrests, the seat interference phenomenon can be more accurately identified by taking the contact points and related reference lines, calculating the change relationship of the relative distance between the front and rear seats, and then judging the seat interference situation.
