if the total number of the accumulated square waves is close to the total number of the square waves corresponding to the time when the automobile door is completely closed, judging that the automobile door outer plate enters an anti-pinch area, continuously detecting whether an anti-pinch strip sends out a closing signal or not by the control device, and if the anti-pinch strip closing signal is detected, starting an anti-pinch program by the control device, namely, stopping the action after the control device controls the driving motor to positively rotate to the automobile door outer plate to be completely opened; if the anti-pinch strip closing signal is not detected, the control device does not start an anti-pinch program, namely, the control device controls the driving motor to continuously rotate reversely until the vehicle door is completely closed;
if the total number of the accumulated square waves is not close to the total number of the square waves corresponding to the time when the vehicle door is completely closed, judging that the outer plate of the vehicle door is not in the anti-pinch area, controlling the driving motor to continuously rotate reversely by the control device, continuously closing the vehicle door, and repeating the steps.
9. The method for controlling an electric side swing door according to claim 7, wherein the total number of square waves corresponding to the maximum value of door opening is determined according to the ratio of the thickness of the human arm to the maximum width of door opening when the door is opened, and as an embodiment, 80% of the total number of square waves corresponding to the maximum value of door opening can be taken.
10. The method for controlling an electric side swing door according to claim 8, wherein the total number of square waves corresponding to the door being closed is determined according to the ratio of the thickness of the human head and the shoulder to the maximum width of the door being opened when the door is closed, and as an embodiment, 60% of the total number of square waves corresponding to the door being closed is taken.
