Control method, control circuit, and control program for power retractable outer mirror for a vehicle
Abstract:
A control method can stop motor operation reliably when a mirror rotator is mechanically locked at a driven end of the mirror rotator. The control method operates a motor 18 according to battery voltage. The motor 18 is operated with an operating time set and is stopped after a lapse of the set operating time, where the operating time is a time required for the motor 18 to drive the mirror rotator 14 from the retracted position or the working position to the working position or the retracted position at which the mirror rotator 14 is locked by a stopper. The control method detects the battery voltage, and decreases the set operating time of the motor 18 when the detected battery voltage is high or increases the set operating time of the motor 18 when the detected battery voltage is low.
