Abstract

본 발명은 와이퍼를 수동으로 조작하지 않고도 떨어지는 물방울량에 따라 자동으로 와이퍼를 구동시킬 수 있는 광센서를 이용한 와이퍼 구동방법에 관한 것으로 종래에는 자동차 앞유리에 빗방울이 떨어지면 운전자가 와이퍼 조작키를 1단 내지 3단으로 수동 조작하여 물방울량에 따라 와이퍼를 구동시켰으나 본 발명에서는 자동차의 앞유리 내부면에 광센서부를 부착하여 유리(1)표면에 떨어지는 물방울의 빛 굴절 정도를 검출하므로 와이퍼를 자동으로 구동시킬 수 있게 한 것이다.The present invention relates to a wiper driving method using an optical sensor that can automatically drive the wiper according to the amount of water drops falling without manually operating the wiper. Conventionally, when raindrops fall on the windshield of the vehicle, the driver presses the first wiper operation key. In the present invention, the wiper is driven according to the amount of water droplets by manual operation. However, in the present invention, the optical sensor unit is attached to the inner surface of the windshield of the vehicle to detect the degree of light refraction of the water droplets falling on the glass 1 surface. It was made possible.
