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...

Abstract

The invention relates to an electric car window anti-pinch parameter automatic matching method. The electric window anti-pinch parameter automatic matching method includes that a car window controller is powered and an interrupt unit regularly sends interrupt request signals to a current collector and a Hall counter respectively when the car window anti-pinch controller is first mounted on a car window; a button for automatically rising the glass of the car window is pressed to start an anti-pinch parameter automatic matching process, an anti-pinch parameter automatic matching unit enables the glass of the car window to move downwards to the bottom automatically and to move upwards to the top automatically, and in the process, the anti-pinch parameter automatic matching unit performs automatic matching for anti-pinch parameters of a motor current threshold and a car window height threshold to obtain the motor current threshold and the car window height threshold; a judging unit judges the validity of the matched anti-pinch parameters; the motor is regarded as to be in rotation blocking when the car window controller detects that the motor current is larger than the current threshold, and then the position of the car window is checked; the car window is judged to be in pinching if the car window is in an anti-pinch area, and the car window is regarded as to be on the top if the car window is in a top area. The electric window anti-pinch parameter automatic matching method can be widely applied to the car window control.

Description

technical field [0001] The invention relates to the field of intelligent electronic control of automobile windows, in particular to an automatic matching method for anti-pinch parameters of electric vehicle windows with an anti-pinch function. Background technique [0002] In traditional anti-pinch electric windows, the window controller detects the current of the window glass lift motor through the current sensor, and at the same time uses the Hall sensor to determine the position of the window glass, so as to make a corresponding response to the state of the window judge. Therefore, in order to make an accurate judgment on the state of the window, it is necessary to pre-set several thresholds of the motor current and the position of the window glass to distinguish between the normal operation of the window, the window reaching the top of the window, and the clamping of the window. different operating states. In the prior art, the threshold parameters required to realize ...
