The invention discloses a wiper angle control method for realizing a wiper blade hiding function of an automobile windscreen wiper, which is characterized in that a motor with a control circuit board is used, the wiper blade hiding function is realized by adopting a control method of different wiper blade stopping positions and lower limit wiping positions, and the initial 0 degree of the motor, the lower limit alpha degree of the motor and the upper limit beta degree of the motor are set; when the windscreen wiper is started for the first time, the control circuit board controls the motor to move from the initial 0 degree to the upper limit position beta degree of the motor, then the normal wiping of the windscreen wiper circulates from the upper limit to the lower limit and from the lower limit to the upper limit, and finally the windscreen wiper is ready to stop. The control circuit board controls the motor to operate from the upper limit position to the initial position of the motor, specifically, the current angle and the current angular speed of the wiper motor are obtained through the angle sensor, input to the MCU central controller for calculation and output to the H-bridge driving circuit through PID closed-loop control, two rotating modes of the motor are achieved, and therefore the function of hiding the wiper blade is achieved.

    本发明公开了一种汽车雨刮实现刮片隐藏功能的刮角控制方法,使用带有控制电路板的电机,采用不同的刮片停靠位置和下极限刮刷位置的控制方法来实现刮片隐藏的功能,设置电机初始0°、电机下极限α°和电机上极限β°,对应刮片刮刷的位置,当雨刮第一次启动时,控制电路板控制电机从初始0°运动到电机上极限位置β°,之后雨刮的正常刮刷都是上极限到下极限和下极限到上极限的循环,直到最后雨刮准备停止时,控制电路板控制电机从上极限位置到电机初始位置运行,具体地,通过角度传感器获取雨刮电机当前角度和角速度,输入给MCU中央控制器进行计算,并通过PID闭环控制输出给H桥驱动电路,实现电机两种旋转方式,从而实现刮片隐藏的功能。
