Ripple anti-pinch circuit and control method thereof
The invention belongs to the technical field of automobile window intelligent control, and discloses a ripple wave anti-pinch circuit and a control method thereof, and the ripple wave anti-pinch circuit comprises a motor control and driving module, a motor current conversion amplification module, a motor direct current extraction processing module, a small current voltage stabilization module, a motor ripple wave current extraction processing module and an on-chip system module. Wherein the system-on-chip module accumulates the number of effective pulses output by the processing module according to the motor ripple current, and judges whether the window glass reaches an anti-pinch area or not according to the accumulated value; and if the vehicle window glass is judged to reach the anti-pinch area and the system-on-chip module detects that the output value of the direct current of the motor extracted from the processing module reaches a threshold value 1, the vehicle window glass is judged to encounter an obstacle in the ascending process, and the system-on-chip module drives and controls the vehicle window motor to stop and then controls the vehicle window motor to rotate reversely so as to enable the vehicle window glass to descend. The ripple anti-pinch circuit provided by the invention is low in cost, small in occupied space and high in precision and reliability.
本发明属于汽车车窗智能控制技术领域，公开了一种纹波防夹电路及其控制方法，电机控制及驱动模块、电机电流转换放大模块、电机直流电流提取处理模块、小电流稳压模块、电机纹波电流提取处理模块、片上系统模块，其中片上系统模块根据电机纹波电流提取处理模块输出的有效脉冲数，将有效脉冲数进行累加，根据累加值判断车窗玻璃是否达到防夹区域；若判断车窗玻璃已达到防夹区域，且所述片上系统模块检测到电机直流电流提出处理模块输出值达到阈值1，则判断车窗玻璃上升过程遇到障碍物，所述片上系统模块驱动控制车窗电机停止后控制车窗电机反转使车窗玻璃下降。本发明提供的纹波防夹电路成本低、占用空间小、精度及可靠性高。
