Abstract
A door-mirror-controlling apparatus includes an ECU, a velocity detector, a turn-signal lamp, and a DC motor; the ECU includes an MPU and a motor driver circuit. The velocity detector detects the velocity of an automobile, and outputs a velocity signal to the ECU. The MPU outputs an outer-turn-start signal to the motor driver circuit when the turn-signal lamp is blinking while the automobile is moving at a predetermined velocity or more. When the motor driver circuit receives the outer-turn-start signal, it outputs a signal to the DC motor and the DC motor rotates such that a reflective surface of a mirror turns outward, away from the automobile, compared to its original state.
