Abstract
The electric rearview mirror system comprising a position sensor which outputs a position signal showing the rotational position of the mirror body, memory device which stores the position signal from the position sensor at a prescribed sampling period, and a motor control circuit which judges the rotational direction of the mirror body based on the change with time of the position signal stored in the memory device and turns off the motor when the judged direction of the motor is opposite to the rotational direction of the mirror body due to the mirror driving mechanism.
