According to an embodiment, a wiper driving device comprises: a sensor unit having a carbon micro coil; a precipitation detection unit outputting an output value corresponding to a different value between first frequency in accordance with a change in an impedance value of the sensor unit and predetermined second frequency; and a control unit determining existence of precipitation and precipitation with the output value outputted through the precipitation detection unit, and determining a wiper driving condition in accordance with the determined result. The first frequency is changed by responding to a change in an inductance value of the carbon micro coil in accordance with the existence of precipitation and the precipitation.

    실시 예에 따른 와이퍼 구동 장치는, 카본 마이크로 코일을 포함하는 센서부; 상기 센서부의 임피던스 값의 변화에 따른 제 1 주파수 및 기설정된 제 2 주파수의 차이 값에 대응하는 출력 값을 출력하는 강우량 감지부; 및 상기 강우량 감지부를 통해 출력되는 출력 값을 이용하여 강우 여부 및 강우량을 판단하고, 상기 판단 결과에 따라 와이퍼 구동 조건을 결정하는 제어부를 포함하며, 상기 제 1 주파수는, 상기 강우 여부 및 강우량에 따른 카본 마이크로 코일의 인덕턴스 값의 변화에 대응되어 변화한다.
