To provide a novel technique for extracting information on an inclination angle of a vehicle with respect to a road surface on the basis of a value detected by an acceleration sensor in auto-leveling control of a vehicle lamp using the acceleration sensor.SOLUTION: A control device of a vehicle lamp includes: a receiving unit for receiving acceleration which is detected by an acceleration sensor and from which vehicle longitudinal direction acceleration and vehicle vertical direction acceleration can be derived; a control unit for generating a control signal for instructing optical axis adjustment of the vehicle lamp, on the basis of variation in ratio between an amount of temporal change of the vehicle longitudinal direction acceleration and an amount of temporal change of the vehicle vertical direction acceleration during at least one of acceleration and deceleration of a vehicle; and a transmitting unit for transmitting the control signal to an optical axis adjusting unit of the vehicle lamp.SELECTED DRAWING: Figure 4

    【課題】加速度センサを用いた車両用灯具のオートレベリング制御において、加速度センサの検出値から路面に対する車両の傾斜角度についての情報を抽出する新たな技術を提供する。【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、車両前後方向および車両上下方向の加速度を導出可能な加速度を受信するための受信部と、車両の加速時および減速時の少なくとも一方における、車両前後方向の加速度の時間変化量と車両上下方向の加速度の時間変化量との比率の変化に基づいて車両用灯具の光軸調節を指示する制御信号を生成するための制御部と、制御信号を車両用灯具の光軸調節部に送信するための送信部と、を備える。【選択図】図4
