Abstract
PURPOSE: To eliminate the need for operations necessary to switch manually, by a method wherein a rain condition is detected by means of a heat-sensitive resistance element located at a portion which is exposed to rain drops outside a car, and an intermittent drive cycle of a wiper changes automatically according to the rain condition.
CONSTITUTION: A detecting means for detecting a rain condition consists of first and second detecting circuits 4 and 5 and a differential amplifier 6. The first detecting means 1 is provided with a thirmistor T1 located at a position exposed to rain drops outside a car, and the second detecting means 2 is equipped with a thirmistor T2 at a position prevented from the exposure to rain drops outside the car. The differential amplifier 6 outputs a detecting signal Vs from outputs Va and Vb of the detecting means 1 and 2, respectively, said detecting signal Vs indicating the rain condition according to an amount of the rain drops touching the thirmistor T1 and a relative wind speed. Said signal Vs is transmitted to an intermittent drive circuit 2, and a cycle, which drives intermittently a wiper motor 3 according to the rain condition, is changed.
