<p>PROBLEM TO BE SOLVED: To make the illuminating direction of a lamp controllable corresponding to the vehicle running attitude simply by providing a vehicle height detecting means on an axle shaft of either the front wheels or the rear wheels. SOLUTION: With regard to an illuminating direction control device 1 for a vehicular lamp causing to change the illuminating direction of the lamp 6 correspondingly to the vehicle attitude in the proceeding direction, a vehicle height detective means 2 for detecting the height variation of either the front or rear wheel axle shaft of the vehicle and a driving means 5 for directing the illumination light of the lamp 6 to the desirable direction are provided. A vehicle attitude calculation means 3 is also provided to calculate the vehicle standstill attitude based on the detection signals from the vehicle height detecting means 2 as well as to regulate the interrelation between the detection signal of the vehicle running attitude and that of the vehicle height detecting means 2 based on vehicle standstill and to calculate the vehicle running attitude from the detection signals of the vehicle height detecting means 2. An illumination control means 4 corrects the illumination direction of the lamp 6 in accordance with the signal from the vehicle attitude calculation means 2 and a signal to keep it in the standard direction is sent to the driving means 5.</p> |
