To perform automatic leveling precisely and stably in any travel state of a vehicle.SOLUTION: A controller for vehicular lighting fixture is configured to: receive acceleration which is detected by an acceleration sensor and from which variation in vehicle attitude angle as angles of front and rear shafts of the vehicle relative to a road surface can be derived, and an angular velocity which is detected by an angular velocity sensor and from which variation in vehicle attitude angle can be derived; perform first mode control to generate a control signal indicating optical-axis adjustment on vehicle lighting fixtures based upon the acceleration detected by the acceleration sensor when acceleration in the front-rear direction of the vehicle is equal to or less than a predetermined value, and second mode control to generate a control signal indicating optical axis adjustments on the vehicular lighting fixtures based upon the angular velocity detected by the angular velocity sensor when the acceleration in the front-rear direction of the vehicle exceeds the predetermined value; and transmit the control signal that the control part generates to an optical axis adjustment part which adjusts the optical axes of the vehicular lighting fixtures.SELECTED DRAWING: Figure 2
【課題】車両の走行状態にかかわらず精度よく安定してオートレベリング制御を行う。【解決手段】車両用灯具の制御装置は、加速度センサで検出される、路面に対する車両の前後軸の角度である車両姿勢角度の変化を導出可能な加速度と、角速度センサで検出される、車両姿勢角度の変化を導出可能な角速度とを受信し、車両の前後方向の加速度の大きさが所定値以下であるときは、加速度センサで検出される加速度に基づき車両用灯具の光軸調節を指示する制御信号を生成する第1モード制御を行い、車両の前後方向の加速度の大きさが所定値を超えているときは、角速度センサで検出される角速度に基づき車両用灯具の光軸調節を指示する制御信号を生成する第2モード制御を行い、制御部が生成した制御信号を車両用灯具の光軸調節を行う光軸調節部に送信する。【選択図】図2
