Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0014] Such as figure 1 As shown, the electric window anti-pinch parameter automatic matching method of the present invention comprises the following steps:
[0015] 1. If figure 2 As shown, a car window anti-pinch control system is set, which includes a motor 1 arranged at the bottom of the car window glass for controlling the movement of the car window glass, and a sampling resistor for obtaining the motor current is set on the input circuit of the motor 1 as the current Sensor 2, the current sensor 2 sends the voltage value at both ends of the sampling resistor to the window controller (not shown in the figure) through a current collector 3, and the window controller calculates the motor current value according to Ohm's law; The output end is provided with a Hall sensor 4, and the Hall sensor 4 is used to obtain the square wave pulse signal of t...
