Power window anti-pinch control method and system
The invention discloses a power window anti-pinch control method and system, and relates to the field of vehicle window control. The method comprises the following steps: obtaining an anti-pinch identification pulse width of each vehicle window pulse width according to a self-learning pulse width of a vehicle window; and when the car window is located in the anti-pinch area and the difference of the anti-pinch identification pulse widths before and after the current moment exceeds a specified threshold value, it is determined that car window anti-pinch needs to be carried out. Anti-pinch control is carried out through the pulse width difference value, due to the fact that the pulse width difference value can reflect the change condition of the car window in the actual movement process, the pulse width of the car window can be lengthened when the car window touches an obstacle, and the pulse width of the car window can be gradually increased when the car window makes contact with the obstacle again, when the car window is located in the anti-pinch designated area, the car window can be prevented from being pinched. According to the method, the anti-pinch identification accuracy of determining whether the anti-pinch operation is performed or not according to the difference of the plurality of anti-pinch identification pulse widths before and after the current moment is relatively high, so that the magnitude of the anti-pinch force of the vehicle window can be identified more accurately, and anti-pinch judgment is accurately performed.
本发明公开了一种电动车窗防夹控制方法及系统，涉及车窗控制领域。该方法的步骤包括：根据车窗的自学习脉宽得到每个车窗脉宽的防夹识别脉宽；当车窗处于防夹区域、且当前时刻前后的若干防夹识别脉宽的差异超过指定阈值时，确定需要进行车窗防夹。本发明通过脉宽差值来进行防夹控制，因为脉宽差值能反映出车窗实际运动过程中的变化情况，车窗碰到障碍物时车窗脉宽会被拉长，而车窗和障碍物再接触过程中车窗脉宽会逐渐变大，所以本发明在车窗处于防夹指定区域时，根据当前时刻前后的若干防夹识别脉宽的差异，来确定是否进行防夹操作的防夹识别精度较高，进而能够更加精准地识别车窗防夹力的大小，从而准确地进行防夹判断。
