ABSTRACT:
The headlight moving apparatus comprises a yaw rate sensor, a headlight position sensor, a vehicle speed sensor, a CPU, and a headlight actuator. The CPU calculates an appropriate headlight turning position on the basis of these three sensor signals. Since the yaw rate sensor can directly detect the vehicle turning motion and direction, it is possible to move the headlights right and left more reliably. Therefore, the adjusted headlights can brighten remote forward road surface when the vehicle runs along a curved road.
