To improve credibility in auto-leveling control with use of an acceleration sensor.SOLUTION: A control device variably controls an optical axis of a vehicle lamp fitting 14 according to a posture change of a vehicle in a pitch direction. This control device comprises: a sensor abnormality determination part 20 which determines existence or absence of any operation abnormality of a first acceleration sensor 11 based on a first acceleration associated to each of a cross direction and a vertical direction of the vehicle which is detected by the first acceleration sensor 11; an angle calculation part 21 which determines a posture angle of the vehicle by use of the first acceleration when it is determined that there is no operation abnormality in the acceleration sensor 11, and which determines a posture angle of the vehicle by use of a second acceleration which is detected by a second acceleration sensor 12 different from the first acceleration sensor 11 when it is determined that there is an operation abnormality in the acceleration sensor 11; and an optical axis setting part 22 which generates a control signal for controlling the optical axis of the vehicle lamp fitting 14 based on the posture angle of the vehicle which is determined by the angle calculation part 21, and feeds the control signal to the vehicle lamp fitting 14.SELECTED DRAWING: Figure 1

    【課題】加速度センサを用いたオートレベリング制御における信頼性を高める。【解決手段】車両のピッチ方向の姿勢変化に応じて車両用灯具14の光軸を可変に制御するための制御装置であって、第1加速度センサ11によって検出される車両の前後方向及び上下方向の各々に対応付けられた第1加速度に基づいて、第1加速度センサ11の動作異常の有無を判定するセンサ異常判定部20と、第1加速度センサ11の動作異常がないと判定された場合には第1加速度を用いて車両の姿勢角度を求め、第1加速度センサ11の動作異常があると判定された場合には第1加速度センサ11とは異なる第2加速度センサ12により検出される第2加速度を用いて車両の姿勢角度を求める角度算出部21と、角度算出部21により求められた車両の姿勢角度に基づいて車両用灯具14の光軸を制御するための制御信号を生成して車両用灯具14へ供給する光軸設定部22を備える。【選択図】図1
