CONTROL DEVICE FOR VEHICULAR LAMP, VEHICULAR LAMP SYSTEM, AND CONTROL METHOD FOR VEHICULAR LAMP

To improve the accuracy of auto-leveling control of a vehicular lamp.SOLUTION: A control device for a vehicular lamp includes: a reception unit 34 that receives a signal from an inclination sensor 32 enabling the derivation of the inclination angle of a vehicle 300; a control unit 36 that outputs an adjustment signal for the optical axis angle of a vehicular lamp 1 in response to a change in the inclination angle while the vehicle is being stopped, and avoids the generation or output of the adjustment signal or outputs a maintaining signal for the optical axis angle in response to a change in the inclination angle while the vehicle is traveling; and a movement determination unit 46 that determines whether the vehicle 300 has moved while an ignition switch 314 is in an off state. The control unit 36 outputs the adjustment signal in response to a change in the inclination angle while the ignition switch 314 is in the off state if the movement determination unit 46 has determined that the vehicle has not moved, and avoids the generation or output of the adjustment signal or outputs the maintaining signal in response to a change in the inclination angle while the ignition switch 314 is in the off state if the movement determination unit 46 has determined that the vehicle has moved.SELECTED DRAWING: Figure 7 【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。【解決手段】車両用灯具の制御装置は、車両３００の傾斜角度を導出可能な傾斜センサ３２の信号を受信する受信部３４と、車両停止中の傾斜角度の変化に対して車両用灯具１の光軸角度の調節信号を出力し、車両走行中の傾斜角度の変化に対して調節信号の生成または出力を回避するか光軸角度の維持信号を出力する制御部３６と、イグニッションスイッチ３１４がオフ状態にある間の車両３００の移動を判定する移動判定部４６と、を備える。制御部３６は、移動判定部４６が移動なしと判定した場合に、イグニッションスイッチ３１４のオフ中の傾斜角度の変化に対して調節信号を出力し、移動判定部４６が移動ありと判定した場合に、イグニッションスイッチ３１４のオフ中の傾斜角度の変化に対して調節信号の生成または出力を回避するか維持信号を出力する。【選択図】図７
