LIGHTING CONTROL FOR MOTOR VEHICLE LAMPS

摘要

A regulating arrangement for inclining lamps on a motor vehicle as a function of the inclination of the longitudinal axis of the vehicle with respect to the road surface. A potentiometer mounted between the chassis and the axle of the vehicle provides a signal representing the inclination of the axis of the vehicle with respect to the road surface. This signal serves as an input to a comparator which develops a difference signal by comparing the potentiometer output with a signal derived from the actual position of the lamp. The difference signal is amplified and applied to a positioning element in the form of a bimetallic member through which the lamps are positioned. A second potentiometer is used to provide the feedback signal for the comparator as a function of the actual displacement of the lamp.
