The invention discloses an efficient vehicle window anti-pinch starting filtering algorithm. The algorithm comprises the following steps that S1, whether a current vehicle window is in an automatic rising process and located in an anti-pinch area or not is judged, if so, S2 is executed, and otherwise, S12 is executed; S2, current motor driving force is calculated, and S3 is executed after calculation is completed; S3, whether a starting filtering enabling flag bit is true or not is judged, S5 is executed if the flag bit is true, and S4 is executed if the flag bit is false; S4, vehicle window anti-pinch judgment and processing are executed, and S12 is executed after the judgment and processing are completed; S5, whether a starting filtering count value is smaller than a protection value ornot is judged, if yes, S6 is executed, and if not, S9 is executed; and S6, one is added to the starting filtering count value, and S7 is executed after completion. According to the efficient vehicle window anti-pinch starting filtering algorithm, when the falling of the motor driving force generated by gap impact force is identified, an anti-pinch threshold value can be compensated, and the phenomenon that the window cannot be normally and automatically closed due to anti-pinch misjudgment caused by gap impact is eliminated.

本发明公开了一种高效的车窗防夹启动滤波算法，包括如下步骤：S1：判断当前的车窗是否为自动上升过程且位于防夹区域内，如果满足进入S2，否则进入S12；S2：计算当前的电机驱动力，计算完成后进入S3；S3：判断启动滤波使能标志位是否为真，标志位为真进入S5，标志位为伪进入S4；S4：执行车窗防夹判断与处理，完成后进入S12；S5：判断启动滤波计数值是否小于保护值，如果小于保护值进入S6，否则进入S9；S6：启动滤波计数值加一，完成后进入S7。本发明在识别到因间隙冲击力产生的电机驱动力跌落时，便可对防夹阈值进行补偿，消除了因间隙撞击而进行防夹误判以至于不能正常自动关窗的现象。
