Abstract
본 발명의 와이퍼 속도 조절장치는 와이퍼의 구동속도를 차량의 주행속도에 따라 가변시키는 것이다.The wiper speed control device of the present invention is to change the drive speed of the wiper according to the running speed of the vehicle.
본 발명은 와이퍼 스위치(1)를 저속 위치에 위시킬 경우에 와이퍼 모터(3)로 흐르는 전류를 제한하는 가변저항(11)을 구비하고, 차속센서(12)가 검술하는 차랴의 주행속도에 따라 콘트롤러(13)가 와이퍼 속도 가변 제어 신호를 출력하며, 이 출력한 제어신호에 따라 가변저항 가변부(14)가 가변저항(11)을 가변시켜 와이퍼 모터(3)로 흐르는 전류의 제한한다.The present invention includes a variable resistor (11) for limiting the current flowing to the wiper motor (3) when the wiper switch (1) is placed at a low speed position, and the vehicle speed sensor (12) checks the driving speed of the vehicle. The controller 13 outputs a variable wiper speed control signal, and the variable resistance variable part 14 varies the variable resistor 11 to limit the current flowing to the wiper motor 3 according to the output control signal.
