PROBLEM TO BE SOLVED: To provide a technique which enhances accuracy of auto-leveling control of a vehicular lighting fixture.SOLUTION: A control device of a vehicular lighting fixture includes: a drive circuit part 110 which connects an on-vehicle battery 328 and the control device without using an ignition switch 326 to supply drive voltage to the control device; a voltage monitoring circuit part 114 which sends voltage information of the on-vehicle battery 328 to the control device in a case of using the ignition switch 326; and a control part 120 which outputs a control signal to an actuator to which the drive voltage is supplied from the on-vehicle battery 328 via the ignition switch 326. The control part 120 corrects an actuator drive voltage value corresponding to the output value of an inclination sensor 116 by a potential difference between voltage supplied to the control device via the drive circuit part 110 and voltage of the on-vehicle battery 328 obtained via the voltage monitoring circuit part 114 to output it to the actuator.
【課題】車両用灯具のオートレベリング制御の精度を高める技術を提供する。【解決手段】ある態様の車両用灯具の制御装置は、イグニッションスイッチ326を介さずに車載バッテリ328と制御装置とを接続し、制御装置に駆動電圧を供給する駆動回路部110と、イグニッションスイッチ326を介した場合の車載バッテリ328の電圧情報を制御装置に送る電圧監視回路部114と、イグニッションスイッチ326を介して車載バッテリ328から駆動電圧を供給されるアクチュエータに制御信号を出力する制御部120と、を備える。制御部120は、傾斜センサ116の出力値に対応するアクチュエータ駆動電圧値を、駆動回路部110を介して制御装置に供給される電圧と電圧監視回路部114を介して得られる車載バッテリ328の電圧との電位差分だけ補正してアクチュエータに出力する。【選択図】図2
