Automatic leveling system for automotive headlamps

摘要

An automatic leveling system has a headlamps optical axes L adapted to tilt vertically relative to a body of a vehicle by driving actuators 10, a control part 16 for controlling the driving of the actuators 10, a vehicle speed sensor 12, a vehicle height sensor 14 and a storage part 20 for storing pitch angle data detected by the vehicle height sensor 14. The control part 16 controls the actuators 10 based on a detected pitch angle such that the optical axes L of the headlamps are inclined to a predetermined angle relative to the road surface.
