Problems solved by technology

In the traditional anti-pinch control logic, the Hall sensor detection mode is usually used, which requires the motor itself to integrate the Hall sensor, which will increase the requirements for the mechanical structure of the motor and increase the cost.

Embodiment Construction

[0029] The window anti-pinch system uses the BMC on the car. Each window on the vehicle is equipped with a window motor 1 for lifting. The window motor 1 is a DC motor. The drive circuit of the window motor 1 is connected to the window of the BMC. The control signal output pin is connected, and the window control input pin of the BMC is connected to the window control button 3, so that the window can be directly controlled through the BMC.

[0030] The window motor 1 is equipped with a motor ripple sampling circuit. The output end of the motor ripple sampling circuit is connected to the BMC. The stroke of the window glass is fixed, and the distance that the motor rotates to pull the window glass is also fixed. The number of waves determines the position of the window glass, so as to achieve regional anti-pinch. While controlling the window, BCM can detect the position of the window and the force generated by the motor, and realize the purpose of stopping and continuing to oper...

Abstract

The invention discloses a vehicle window anti-pinch system. A vehicle window motor for rising and falling is arranged on each vehicle window of a vehicle. The vehicle window motors are DC motors. Driving circuits of the vehicle window motors are all connected with the vehicle window control signal output pin of a BMC. The vehicle window control input pin of the BMC is connected with a vehicle window control button. The vehicle window motors are each provided with a motor corrugation sampling circuit. The output ends of the motor corrugation sampling circuits are connected with the BMC. The limit on the motors is greatly reduced, no special customized motor is needed, through the calibrating test on an ordinary vehicle window motor, the vehicle window anti-pinch function can be achieved, the vehicle window functions can be enhanced, and the use comfort can be improved.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle window anti-pinch detection part of a vehicle body controller (abbreviated as BCM hereinafter). Background technique [0002] Electric windows are one of the most frequently used functions on the vehicle, and safety issues during their use have also been focused on. Therefore, it is a development trend to add anti-pinch functions to the window functions. The traditional anti-pinch control logic usually adopts the Hall sensor detection mode, which requires the motor itself to integrate the Hall sensor, which will increase the requirements for the mechanical structure of the motor and increase the cost. Contents of the invention [0003] The technical problem to be solved by the invention is to realize a simple and reliable automobile window anti-trap system. [0004] In order to achieve the above object, the technical solution adopted by the present invention is:...
