ABSTRACT:
A wiper controller comprises a power source, a wiper drive motor, a power switch, a wiper switch, a position detector for detecting the position of a wiper on the windshield of a vehicle, a drive control circuit for controlling the power supply to the motor, and a switch circuit for controlling the power supply to the drive control circuit. The drive control circuit is connected to the power source, and controls the power supply to the motor from the power source, based on the ON/OFF status of the power switch and wiper switch, and also based on information from the position detector. The drive control circuit causes the wiper to stop at a predetermined position on the windshield. The switch circuit allows power to be supplied to the drive control circuit when the power switch is switched on, and further allows the power to be supplied, for a predetermined period of time, after the power switch is switched off.
