<p>PROBLEM TO BE SOLVED: To provide an optical axis adjustment system for a vehicle, which prevents an error or the optical axis direction of vehicle light equipment even in a case when a supply voltage fluctuates in a wide range, in a simple system constitution without requiring additional parts. SOLUTION: The optical axis adjustment system for the vehicle comprises a control unit 12 for outputting a optical axis adjustment command signal Sa, and an actuator 14 for adjusting the optical axis of vehicle light equipment according to a ratio between the adjustment command signal Sa and the supply voltage Vb, wherein a controller 18 monitors the supply voltage Vb, which is to be supplied to a D/A converter 20 and the actuator 14, to halt the actuator 14 in its present position upon fluctuating of the supply voltage Vb over its average value and t restore the operation of the actuator 14 upon returning of the supply voltage Vb to a normal value.</p> |
