AUTO HEADLAMP LEVELING APPARATUS AND METHOD THEREOF

摘要

PURPOSE: An automatic headlamp leveling apparatus and a method of the same are provided to improve the controlling precision of the radiation angle of a headlamp by integrating a front or a rear detection sensor into an electrical control unit. CONSTITUTION: A plurality of height sensors(110, 111) detects the height change of the front side or the rear side of a vehicle based on the load change of the vehicle. A tilt sensor(130) detects the tilt of the vehicle based on a road state. A speed sensor(60) detects the driving speed of the vehicle. A lamp controller(140) calculates the radiating angle of head lamps based on the height, the tilt and the driving speed of the vehicle.
