However, if there is an obstacle in the direction of movement during adjustment, the seat will hit and press against the obstacle, possibly causing unnecessary losses and a certain safety problem. In order to avoid this, vehicle seats generally have an anti-pinch function, which means that the seat automatically stops moving when encountering an obstacle during movement. Because the seat meets the obstacle in the moving process, the working current of the driving motor of the seat can be increased and the motor rotating speed can be reduced due to the blocking effect of the obstacle, in the prior art, whether the seat bumps on and presses the obstacle can be judged by detecting the working current and the rotating speed of the motor, so that whether the anti-pinch function is triggered or not is determined. However, in existing solutions, the anti-pinch function is typically triggered only when the seat has impacted and pressed against an obstacle, and thus there is a need for improvement in existing solutions.

Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear and obvious, the application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the particular embodiments described herein are illustrative only and are not limiting upon the application.
As shown in fig. 1, a schematic view of a seat 1 of a vehicle is shown. Wherein the seat 1 mainly comprises: a backrest 11 and a seat cushion 12. Wherein the seat 1 can move back and forth in the horizontal direction, for example, the seat cushion 12 part of the seat 1 can be slidably mounted on a slide rail in the horizontal direction, and the seat cushion 12 part can slide on the slide rail under the drive of a seat motor, thereby driving the whole seat 1 (including the backrest) to move back and forth. Similarly, the angle of inclination of the back rest 11 may also be adjustable, for example, the back rest 11 may be adjusted to be inclined forwardly or rearwardly or partially perpendicular to the seat cushion 12 under the drive of the back rest motor. In the structure of the seat 1 in the drawings, the seat 1 may collide with a nearby obstacle during the rearward movement of the seat 1 or the rearward adjustment of the backrest 11, and thus may cause a certain property loss or present a certain safety problem. To solve this problem, the seat 1 is generally configured with an anti-pinch function, that is, based on the principle that the blocking effect of an obstacle on the seat causes the operating current and the rotation speed of the motor to change, whether the seat hits the obstacle is determined by detecting the operating current and the rotation speed of the motor, thereby triggering the anti-pinch function. However, in the prior art, the anti-pinch function is normally triggered only when the seat 1 has hit and started to press against an obstacle, and thus there is a certain time delay. In some vehicles, however, the location of the obstacle is relatively fixed, such as some compact cars, two-door sports cars or sedans, with a smaller space in the rear row, the primary obstacle being the roof of the rear row. Thus, for a scenario where the position of these obstacles is relatively fixed (or where the position of the obstacles may be predetermined), the inventors of the present application realized that the impact position may be calibrated in advance, and then the anti-pinch operation may be triggered by detecting the position of the seat and the backrest, so that the anti-pinch operation is triggered when the seat is about to strike the obstacle or just touches the obstacle, thereby avoiding the conventional anti-pinch mode from being triggered. The principle of an embodiment of the present application will be described with reference to fig. 2.
As shown in fig. 2, a schematic view of the movement stroke of the seat 1 and the backrest 11 is shown. As shown, the seat 1 is movable in the horizontal direction between positions a and C, a being the limit position for the rearward movement of the seat, i.e. when the seat 1 is moved rearward to a, it will not be able to move rearward any more. Similarly, C may represent an extreme position of forward movement of the seat 1. The backrest 11 is adjustable between positions D and F, where D represents the extreme position of back adjustment and F represents the extreme position of back forward adjustment. Wherein A, C, D and F can be predetermined, for example, set prior to shipment, or calibrated by means such as testing. Note that the designations of A, C, D and F in the drawings are merely illustrative and are not intended to limit the range of movement of the seat, the range of adjustment angles of the backrest, and the like. On the basis of A, C, D and F, the embodiment of the present application introduces a position B (hereinafter referred to as a second position) and a position E (hereinafter referred to as a first position), wherein B is located in the movement stroke of the seat, and E is located in the adjustment stroke of the backrest, that is, B may be the position of the seat at a certain moment, and E may be the position of the backrest at a certain moment.
Wherein B and E are predetermined based at least on the obstacle, and B and E have the following meanings:
position B represents: when the backrest is located between D and E, the seat is in a critical position to collide with an obstacle when the seat moves rearward.
Position E represents: when the seat is located between a and B, the seat collides with an obstacle at a critical position when the backrest is adjusted backward.
That is, both B and E have the meaning of the critical position of the seat against the obstacle, and thus the detection of whether the seat is moved to B or the backrest is adjusted to E during the backward movement of the seat or the backward adjustment of the backrest can be used as a basis for whether the anti-pinch operation is triggered. In this way, the positions of the seat and the backrest are mainly referred, and the working current and the rotating speed of the motor are not required to be referred, so that the method is completely different from the existing scheme, and meanwhile, the anti-pinch operation can be triggered when the seat is about to strike an obstacle or just contacts the obstacle, so that the anti-pinch operation is prevented from striking and squeezing the obstacle in advance, and the safety is improved. With reference to fig. 1 and 2, embodiments of the present application will be described in further detail below with reference to fig. 3 to 7.
Fig. 3 is a schematic flow chart of an embodiment of the anti-pinch method of the vehicle seat of the present application. Wherein fig. 3 mainly illustrates how the anti-pinch is performed when the seat is moved backwards. Specifically, the embodiment of fig. 3 includes the steps of:
step S32, whether the first condition is met is detected.
Wherein the first condition includes three sub-conditions, sub-condition 321: the seat is moving backward; sub-condition 322: the backrest is positioned between the D and the E; sub-condition 323: the seat moves rearward to B.
In this case, step S32 may sequentially detect whether or not the three sub-conditions 321 to 323 in the first condition are satisfied. For example, step S32 may first detect whether the seat is moving backward; when step S32 detects that the seat is moving backward, it is further detected whether the backrest is located between D and E; when step S32 detects that the backrest is located between D and E, it is again detected whether the seat is moved backward to B. In addition, the order of detection of the three sub-conditions 321 to 323 may be changed, for example, whether the backrest is located between D and E is detected first, and when the backrest is detected to be out of the range, detection of other sub-conditions is not performed.
Wherein, in detecting whether the sub-condition 323 is satisfied, it can be achieved by detecting whether the seat is located between B and C. For example, when it is detected that the seat is not located between B and C, the seat is considered to have moved to B.
Step S34, when the step S32 detects that the first condition is met, anti-pinch operation is executed.
Wherein when step S32 detects that the first condition is satisfied, indicating that continued rearward movement of the seat will strike and crush the obstacle, step S34 performs an anti-pinch operation in order to avoid this. Wherein the anti-pinch operation may include at least one of: controlling the seat to stop moving; controlling the backrest to adjust forward, for example to a position between E and F; and controlling the seat to move forward.
In the present embodiment, when the seat moves rearward, it is determined whether the anti-pinch operation is performed by determining whether the backrest is located between D and E, and determining whether the seat moves to B. Therefore, the anti-pinch device can realize anti-pinch before the seat collides with the obstacle, thereby avoiding the traditional anti-pinch scheme from being triggered and having higher safety.
Fig. 4 is a schematic flow chart of an embodiment of the anti-pinch method of the vehicle seat of the present application. Fig. 4 mainly illustrates how an embodiment of the application performs anti-pinching when adjusting the backrest. Specifically, as shown in fig. 4, the anti-pinch method includes the following steps:
step S42, whether the second condition is met is detected.
Wherein the second condition includes three sub-conditions 421 to 423, respectively sub-condition 421: the backrest is being adjusted backwards; sub-condition 422: the seat is positioned between A and B; sub-condition 423: the backrest is adjusted back to E.
Step S42 may sequentially detect whether the three sub-conditions 421 to 423 are satisfied. For example, step S42 first detects whether the backrest is being adjusted backward; when it is detected that the backrest is being adjusted backward, step S42 again detects whether the seat is located between a and B; when it is detected that the seat is located between a and B, step S42 again detects whether the backrest is adjusted backward to E; when the backrest is detected to be adjusted to E backwards, the second condition is satisfied; when any of the above sub-conditions is not met, it is indicated that the second condition is not met. In addition, the detection sequence of the three sub-conditions 421 to 423 may be changed, for example, the sub-condition 422 is detected first, and when the sub-condition 422 is not satisfied, the backrest will not collide with the obstacle regardless of the adjustment, so that the detection of other conditions is not performed.
In the above sub-condition 423, whether the backrest is adjusted to E backward may be determined by detecting whether it is located between E and F. For example, when it is detected that the backrest is not located between E and F, the sub-condition 423 is considered satisfied.
Step S44, when the step S42 detects that the second condition is satisfied, anti-pinch operation is performed.
Wherein when step S42 detects that the second condition is satisfied, indicating that the backrest continues to be adjusted rearward will strike and squeeze the obstacle, step S44 performs an anti-pinch operation, for example, at least one of the following operations: controlling the backrest to stop adjusting; controlling the seat to move forwards; and controlling the backrest to be adjusted forwards.
In the present embodiment, at the time of the back adjustment, whether or not the anti-pinch operation is performed is determined by determining whether or not the seat is located between a and B, and determining whether or not the back is adjusted to E. Therefore, the anti-pinch operation can be realized before the seat collides with the obstacle, the traditional anti-pinch scheme is prevented from being triggered, and the safety is higher.
Fig. 5 is a schematic flow chart of an embodiment of the anti-pinch method of the vehicle seat of the present application. As shown, under the user' S operation, step S50 controls the seat or the backrest to move in the movement direction instructed by the user, for example, to move the seat forward or backward and to adjust the backrest forward or backward.
Next, in step S51, it is checked whether the anti-pinch function described in the embodiment of the present application is turned on, and in an example, the user may turn on or off the anti-pinch function of the embodiment of the present application through a physical key provided or through an operation interface. When step S51 checks that the anti-pinch function is not enabled, the process returns to step S50. When the step S51 detects that the anti-pinch function is turned on, the step S521 is continued. It should be noted that, in this embodiment, there may be two sets of anti-pinch functions, one set is a traditional anti-pinch function, which is turned on by default, and the other set is an anti-pinch function shown in the embodiment of the present application, which may be set by a user to turn on or not; of course, the anti-pinch function of the present embodiment may also be set to a default on state.
In step S521, it is detected whether the seat is moving backward, if yes, step S522 is executed, if no, step S531 is executed, whether the backrest is adjusted backward is detected, if yes, step S532 is executed, and if not, step S50 is executed. The execution sequence of step S521 and step S522 may be adjusted or executed simultaneously, for example, when step S51 determines that the anti-pinch function is enabled, step S531 is executed first, and when the determination result of step S531 is no, step S521 is executed again.
In step S522, it is determined whether the backrest is located between D and E, and if yes, step S523 is performed; if the determination result is no, it indicates that the seat will not collide with the obstacle no matter how it is moved, so the process returns to step S50.
In step S523, it is determined whether the seat is located between B and C, and when step S522 is satisfied, if the seat is located between B and C, the position of the seat can be adjusted normally, so when the determination result of step S523 is yes, the execution returns to step S50. When the determination result of step S523 is no, it is indicated that the seat has moved to B, and step S524 is performed.
In step S524, the seat is prevented from striking and pressing against an obstacle by controlling the seat to stop moving or controlling the backrest to be adjusted forward; and simultaneously prompts the driver or the related condition of the passengers, for example, prompts the user that the anti-pinch function is triggered in a man-machine interaction mode.
In step S532, it is determined whether the seat is located between a and B, and when the determination result is yes, step S533 is performed; when the determination result is no, it means that the seat is located between B and C, and when the seat is located in this position range, the backrest can be arbitrarily adjusted within its adjustment range, so that the step S50 is returned to be performed.
In step S533, it is determined whether the backrest is located between E and F, wherein in the case where step S532 is satisfied, the backrest can be normally adjusted between E and F without collision with an obstacle, so when the determination result of step S533 is yes, the execution of step S50 is returned, and when the determination result of step S533 is no, it is indicated that the backrest has been adjusted to E, and thus the anti-pinch operation shown in step S534 is executed.
In step S534, control the backrest to stop adjusting and/or control the seat to move forward to avoid striking an obstacle; meanwhile, in step S534, the driver or the passenger may be prompted in a manner of man-machine interaction or the like that the anti-pinch function of the present embodiment is triggered.
By means of the embodiment of fig. 5, triggering of the anti-pinch function before hitting an obstacle is achieved by means of the positional relationship rather than the operating current and the rotational speed of the motor, whereby the safety of the seat control is improved.
