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-trap method and device for an electric car seat. The anti-pinch method for an electric car seat includes: judging whether the seat motor is running stably; if the seat motor is running stably, during the operation of the seat motor, It is judged in real time whether the difference between the real-time running speed of the seat motor and the anti-trap reference speed is greater than the preset speed difference; when the difference is greater than the preset speed difference, an anti-trap control signal is generated and output to the seat motor. The anti-trapping method and device of the automobile electric seat provided by the invention realizes the anti-pinch function of the electric seat during the action.

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...
