Ripple anti-pinch position compensation method and device
The invention discloses a ripple anti-pinch position compensation method and device. A current ripple pulse state is detected through current ripples when a motor normally drives a vehicle window to move and a current flows through, and whether a vehicle window stop command is triggered or not is judged. In the process of stopping the output of the motor to the real physical position of the motor,the current disappears, the current ripple pulse disappears, the system is switched to the process of inertia motion after the motor stops, the number of voltage ripple pulses generated by back electromotive force is collected at the moment, the distance of glass movement in the process of inertia motion of the motor is calculated according to the collected number of voltage ripple pulses of theback electromotive force, and the anti-pinch position is compensated according to the distance. The ripple anti-pinch position compensation method and device can compensate the anti-pinch position, are accurate in compensation, are not influenced by factors such as the vehicle window environment, the aging degree of an adhesive tape and the like, ensure the accuracy of the anti-pinch position, andimprove the reliability and the safety.
本发明公开了一种纹波防夹位置补偿方法及装置，在电机正常驱动车窗运动有电流流过时，通过电流纹波检测电流纹波脉冲状态,判断车窗停止命令是否触发。电机输出停止到电机真正物理位置停止的过程中，电流消失进而电流纹波脉冲消失，系统切换到在电机停止后惯性运动的过程，此时采集反电动势产生的电压纹波脉冲数量,通过采集的反向电动势的电压纹波脉冲数量，计算得出电机惯性运动过程中玻璃移动的距离，以此距离对防夹位置进行补偿。本发明能够对防夹位置进行补偿，其补偿准确，不受车窗环境、胶条老化程度等因素的影响，保证了防夹位置的精确性，提高了可靠性和安全性。
