Embodiment Construction

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

[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 BCM. The stroke of the window glass is fixed, and the distance that the motor rotates to pull the window glass is also fixed. The quantity judges the position of the window glass, so as to realize the area 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 operate if resistance is encountered during the operation of the window through...

Abstract

The invention discloses a window anti-pinch system. Each window on the vehicle is equipped with a window motor for lifting and lowering. The window motor is a DC motor, and the driving circuit of the window motor is a BMC window motor. The control signal output pin is connected, the window control input pin of the BMC is connected with the window control button, the window motor is provided with a motor ripple sampling circuit, and the output end of the motor ripple sampling circuit is connected to the BMC . The present invention greatly reduces the restriction on the motor, does not need to customize the motor, and can realize the anti-pinch function of the window through the calibration test on the common window motor, and can enhance the function of the window and improve the comfort of use.

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:...
