<p>PURPOSE:To allow the radiation direction of an illuminating lamp to always coincide with the advance direction of a vehicle by detecting a high luminance light source in front of a vehicle and judging the state of a road in front and changing the direction of the main optical axis of the illuminating lamp according to the shape of the road. CONSTITUTION:A detecting means SC for detecting the high luminance light source in the advance direction viewfield of a vehicle is installed, and a road state judging means RF for judging the shape of a road in front on the basis of the state of the high luminance light source which is detected by the detecting means SC is installed. A control means CO which drives an illuminating lamp driving means MO on the basis of the shape of the road which is judged by the road state judging means RF and changes the direction of the main optical axis of an illuminating lamp LA is installed. Further, an illuminating lamp driving means MO which changes the main optical axis of the illuminating lamp LA at early stage according to the shape of the road in front by the control means CO is installed. Therefore, the recognition performance for the front part by a driver in the night traveling on a curve, etc. can be improved.</p> |
