【摘要】In order to avoid the erroneous judgement produced by the motor discontinuous current,which is caused by the gap between mechanical friction and mechanical transmission,the automobile power window anti-pinch control strategy is proposed through combi-ning the motor Hall pulse signal detection and mechanical power calculation. Motor Hall pulse signal detection is used to judge whether to reach the window glass anti-pinch region and the upper limit,then the mechanical power window motor is calculated to achieve the accu-rate judgment to the detection window of obstacles. Based on calculating the main parameters of power window transmission system and the motion model of the lifting and downing window of DC motor,the power window anti-pinch system model is set up based on the MATLAB/Simulink,and the simulation has been done. The simulation shows that the power window anti-pinch control strategy,com-bined power window motor Hall pulse signal detection with mechanical power calculation,can accurately detect the anti-pinch region,ef-fectively to avoid inadvertent occlusion accidents,enhancing the safety of the car.%为避免由于机械摩擦的变化和机械传动的间隙而造成电机电流不连续产生的误判，提出电机霍尔脉冲信号检测与机械
功率计算相结合的汽车电动车窗防夹控制策略。

检测电机霍尔脉冲信号并判别车窗玻璃是否运行至防夹区和上限位，然后计算电机的机械功率实现对车窗障碍物的准确判断；在计算汽车电动车窗传动系统重要参数和建立永磁直流电机驱动车窗运动模型的基础上，基于MATLAB/Simulink建立汽车电动车窗防夹系统模型并进行仿真。

结果表明：基于电机霍尔脉冲信号检测与机械功率计算相结合的电动车窗防夹控制策略可准确检测车窗防夹区域，有效地避免了误夹事故的发生，提升了汽车的安全性。
