Logic algorithm for anti-pinch of electric tail gate
The invention discloses an anti-pinch logical algorithm for an electric tail gate. The anti-pinch logical algorithm comprises the following steps of S1, opening the electric tail gate; s2, the speed average value in the operation process of the electric tail gate driving motor is collected; s3, a speed threshold value is set, when it is collected that the average value of the running speed of the electric tail gate driving motor is larger than or smaller than the threshold value, it is judged that the situation is an anti-pinch situation, and the step S6 is automatically executed; s4, motor driving current is collected, and a change rate curve is drawn according to the collected driving current; s5, a current change threshold value is set, when the collected driving current change rate is larger than or smaller than the threshold value, it is judged that the situation is an anti-pinch situation, and the step S6 is automatically executed; and S6, the tail gate stops working. The anti-pinch action can be recognized more accurately, the false triggering phenomenon is reduced, the algorithm can adapt to environment changes, and the influence of the environment and other aspects on system judgment is reduced.
