System Construction and Operation
Headlight auto leveling system adjusts the optical axis of the headlight automatically to be suitable for the varied vehicle position while the headlights are lit. It consists of front height sensor (1), rear height sensor (2), headlight auto leveling control module (3), headlight leveling actuator (4) and headlight auto leveling warning light (5).
With more passenger(s) or luggage in the vehicle, the vehicle position differs from that in such vehicle state with one person and no load in the vehicle and angle of the headlight optical axis varies accordingly. This system automatically adjusts the varied angle to maintain the optical axis properly.
