Problems solved by technology

[0004] However, in the actual application process, due to the large driving force of the seat motor, the car electric seat is prone to obstruction by obstacles during the forward and backward translation of the seat and the positive and negative rotation of the backrest along the axis, that is, there is pinch. Potential for passengers to cause safety hazard

Embodiment Construction

[0048] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] The invention provides an anti-pinch method for an electric seat of an automobile to provide an anti-pinch scheme during the action of the electric seat of the automobile.

[0050] Specifically, the automobile electric seat anti-pinch method, such as figure 1 shown, including:

[0051] S101, judging whether the seat motor runs stably;

[0052] In a specific practical application, the judgment standard may be the running time of the seat motor, that is, by judging whether the running time of the seat motor exceeds the second preset time, it is judged whether the seat motor is running stably; If the duration exceeds the second preset duration, it is determined that the seat motor is running stably. The second preset duration ca...

Abstract

The invention provides an anti-clamping method and device for an electric seat of a car. The anti-clamping method comprises the following steps: judging whether the operation of a seat motor is stable; if the operation of the seat motor is stable, judging whether the difference between the real-time operation speed of the seat motor and the anti-clamping reference speed is greater than a preset speed difference in real time in the operation process of the seat motor; when the difference is greater than the preset speed difference, generating and outputting an anti-clamping control signal to the seat motor. The anti-clamping method and device provided by the invention have the advantage that the anti-clamping function in the movement process of the electric seat is realized.

Description

technical field [0001] The invention relates to the technical field of automobile electric seats, in particular to an anti-pinch method and device for automobile electric seats. Background technique [0002] Compared with the transmission manual seat, the car electric seat system has many advantages, such as labor saving, position memory function, etc., and is currently more and more popular among users. [0003] The movement of the car electric seat is generally controlled by the seat motor through the transmission mechanism. Most of the seat motors on the market are open-loop controlled, that is, the seat motor is directly connected to the positive and negative ends of the battery, and the battery voltage is used to drive the seat motor. , so that the car electric seat can realize up to eight directions of movement, respectively, the front and rear translation of the seat, the up and down translation of the seat cushion, the positive and negative rotation of the seat cushi...
