<p><P>PROBLEM TO BE SOLVED: To provide an auto-levelling system for a head lamp which can properly illuminate a forward place of the automobile and thus can ensure driver's forward visibility even when the axis of irradiating light of the head lamp is significantly directed downward upon rapid deceleration of an automobile. <P>SOLUTION: The auto levelling system for a vehicle lamp comprises a lamp that can apply a low beam and a high beam and an irradiation control means that deflects vertically the irradiation direction of the low beam depending upon the posture of the vehicle. The irradiation control means controls the lamp, so that the high beam is applied when the posture of the vehicle is lowered to a larger extent than a reference pitch angle, and the driver's forward distant visibility is ensured by high beam irradiation when the front part of the vehicle body is significantly directed downward, for example, by a brake operation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
