본 발명은 자동차의 레인 센서 및 그 제어 방법에 관한 것으로, 윈드쉴드의 글래스 사양에서 맞춰서 레인 센서의 감도를 튜닝함으로써 동일한 강우 조건에서도 윈드쉴드의 글래스 사양에 따라 강우량 측정 결과가 달라지는 문제를 해결하는데 그 목적이 있다. 이를 위해 본 발명에 따른 레인 센서의 글래스 사양 판별 방법은, 자동차의 윈드쉴드에서 반사되는 광을 수신하여 얻은 수광 신호로부터 윈드쉴드의 글래스 사양을 판별하는 단계와; 수광 신호에 글래스 사양 별 파라미터 튜닝을 적용하여 글래스 사양의 상이함으로 인해 발생하는 글래스 사양 별 수광 신호들 사이의 편차를 제거하는 단계를 포함한다.

    A rain sensor of a vehicle and a control method thereof are provided to solve a problem that a measurement result of rainfall varies according to a glass specification of a windshield even under the same rainfall condition by tuning sensitivity of the rain sensor in accordance with the glass specification of the windshield. For this, a method of determining the glass specification of the rain sensor includes determining the glass specification of the windshield from a light-receiving signal obtained by receiving light reflected by the windshield of the vehicle, and eliminating a deviation between light-receiving signals by glass specification, which is caused by a difference in the glass specification, by applying parameter tuning according to a glass specification to the light-receiving signal.
