Abstract

본 발명은 우천시 와이퍼구동에 따라 자동차윈도우에 대향하도록 설치된 적외선발광소자로부터 방사되어 적외선수광소자에서 수광되는 적외선의 양을 기초로 자동차윈도우상에 흐르는 우량(雨量)의 정도를 판단하여 자동으로 와이퍼의 구동속도를 조절하기 위한 자동차와이퍼의 구동속도자동제어장치 및 그 제어방법에 관한 것으로, 자동차윈도우(E)의 미러면(F)에 대향하여 설치된 적외선감지부(10)의 적외선발광소자(A)로부터 적외선을 방사시킨 후 그 미러면(F)에서 반사되어 적외선수광소자(C)에서 수광되는 적외선의 양을 기준데이터기억부(12)에 기억된 기준데이터와 비교한 결과 수광된 적외선의 양이 적을 경우 자동으로 와이퍼구동모터(16)를 통해 와이퍼(18)의 구동속도를 고속으로 하고 수광된 적외선의 양이 많을 경우에는 자동으로 와이퍼구동모터(16)를 통해 와이퍼(18)의 구동속도를 저속으로 되도록 한 것이다.The present invention is to determine the degree of rainwater flowing on the car window based on the amount of infrared light emitted from the infrared light emitting element installed to face the car window in accordance with the wiper driving in rainy weather, the automatic wiper The present invention relates to an automatic drive speed control device for a vehicle wiper for adjusting the drive speed and a control method thereof, and to an infrared light emitting element (A) of an infrared ray sensing unit (10) provided to face a mirror surface (F) of an automobile window (E). After radiating infrared rays from the mirror surface F, the amount of infrared rays received as a result of comparing the amount of infrared rays reflected by the mirror surface F and received by the infrared light receiving element C with the reference data stored in the reference data memory 12 is determined. If it is small, the wiper driving motor 16 automatically speeds up the driving speed, and if the amount of received infrared light is large, the wiper automatically Is one such that the drive speed of the wiper 18 through the motor 16 at a low speed.
