Car window anti-pinch control method and car window control system with anti-pinch function
The invention discloses a car window anti-pinch control method and a car window control system with an anti-pinch function. The car window control system comprises a car body domain controller, a main driving car window switch module, an auxiliary driving car window switch module, a left rear car window switch module and a right rear car window switch. Whether vehicle window glass is in an anti-pinch area is judged according to the accumulated number of wave crests or the accumulated number of wave troughs of vehicle window motor ripple current, whether an object is pinched or not is judged according to the vehicle window motor speed and the vehicle window motor acceleration, the anti-pinch accuracy can be improved, and the situation that a system mistakenly pinches is reduced; each car window controller and each car window motor ripple current acquisition circuit are respectively integrated in the corresponding car window switch module, and are close to the corresponding car window motor, so that the interference can be avoided, the car window motor ripple current acquisition precision can be improved, and the false anti-pinch condition of the system can be further reduced; communication is achieved through the main LIN bus and the private LIN bus, connecting wire harnesses can be reduced, the cost and weight of the whole vehicle are reduced, and platform design of the whole vehicle is facilitated.
本发明公开了一种车窗防夹控制方法及带防夹功能的车窗控制系统，包括车身域控制器、主驾车窗开关模块、副驾车窗开关模块、左后车窗开关模块和右后车窗开关。其根据车窗电机纹波电流的波峰累计个数或者波谷累计个数来判断车窗玻璃是否处于防夹区域，根据车窗电机速度和车窗电机加速度判断是否夹到了物体，能提高防夹准确度，减少系统误防夹的情况；各个车窗控制器和各个车窗电机纹波电流采集电路分别集成在对应的车窗开关模块中，其靠近对应的车窗电机，能避免干扰，提升车窗电机纹波电流采集的精度，更进一步减少系统误防夹的情况；通过主LIN总线和私有LIN总线实现通信，能减少连接线束，降低整车成本与重量，有利于进行整车平台化设计。
