Abstract

PURPOSE: To make the driving easier by providing a detector in the vehicle for detecting the amount of rain drop colliding against the outer face while automatically changing the wiping amount per unit time in accordance with the amount of rain drop.
CONSTITUTION: Detector 1 comprised of Piezo-electric pickup is fixed on the inner face at end portion not hindering the view of front glass, where the rain drop collides against the front glass to transmit the vibration to the detector 1. Electrical output signal from detector 1 is supplied through filter 2 to the integrating circuit 3 which produces output voltage signal proportional to the amount of rain drop to the amplifier 4 thus to rotate the intermittent driving motor 5. The motor 5 rotates the cam 6 to close the switch 7 thus to rotate the wiper motor and to operate intermittently.
