The invention discloses an anti-pinch control method for an electric automobile seat. The method comprises the steps of: performing dynamic weighted summation of weighting coefficient self-adaptive adjustment on a working current I, a rotating shaft rotating period T and a rotating shaft rotating speed N; obtaining an anti-pinch decision factor [sigma]; judging the condition that [sigma] is greater than [lambda]* Fmax; determining whether an anti-pinch measure needs to be started at the current sampling moment; and combining the advantages of high reliability of working current anti-pinch judgment, high anti-pinch judgment speed of the rotating shaft rotating period and good anti-pinch judgment stability of the rotating shaft rotating speed to realize quick and accurate electric automobileseat anti-pinch control, improve the use safety of the electric automobile seat, and reduce the risk that the electric automobile seat clamps foreign matters. Through the cooperation of the self-adaptive adjustment modes of a current weighting coefficient Ki, a periodic weighting coefficient Kt and a rotating speed weighting coefficient Kn in the steps S2-1 to S2-3, the anti-pinch judgment accuracy of the electric automobile seat can be further improved, and the anti-pinch control method has the advantage of being high in anti-jamming performance.

    本发明公开了一种电动汽车座椅防夹控制方法,通过将工作电流I、转轴转动周期T、转轴转速N进行加权系数自适应调节的动态加权求和,得到防夹决策因子∑,并以此进行∑>λ*F的条件判断,确定当前采样时刻是否需要启动防夹措施,能够结合工作电流防夹判断可靠性高、转轴转动周期防夹判断速度快、转轴转速防夹判断稳定性好的优点,实现快速准确的电动汽车座椅防夹控制,提高了电动汽车座椅的使用安全性,降低了电动汽车座椅夹住异物的风险。通过步骤S2‑1至步骤S2‑3分别对电流加权系数K、周期加权系数K和转速加权系数K的自适应调节方式的配合,能进一步提高电动汽车座椅防夹判断的准确性,具有抗干扰性能强的优点。
