To provide a leveling control device of a vehicular lamp which shortens a designing time of a vehicle, reduces production unit cost and decrease weight of a car body to improve fuel consumption, by substituting a vehicle height sensor.SOLUTION: A leveling control device of a vehicular lamp includes an acceleration sensor 10, a wheel speed sensor 20, a lamp 60 arranged so as to apply light to the surrounding of a vehicle, a driving part 50 arranged so as to control a direction of light applied to the front side of the lamp 60, and a control part 40 which calculates a value of a dynamic inclination of the vehicle with respect to a road by using the acceleration sensor in the circumstances of acceleration or deceleration of the vehicle when the vehicle is traveling, thereafter calculates a value of a first static inclination of the vehicle based on the value of the dynamic inclination of the vehicle, calculates the value of second static inclination of the vehicle by using the acceleration sensor and a road gradient value of a road on which the vehicle is arranged when the vehicle is stopped, and thereafter, controls the direction of light applied on the front side of the lamp based on the value of the calculated first static inclination or the value of the second static inclination.SELECTED DRAWING: Figure 1

    【課題】車高センサーを代替して車両の設計時間を短縮し、生産単価を削減し、車体の重量を減少させて燃費を改善する車両用ランプのレベリング制御装置を提供する。【解決手段】車両用ランプのレベリング制御装置は、加速度センサ10と、ホイール速センサー20と、車両の周辺に光を照射するように配置したランプ60と、ランプ60の前方に照射される光の方向を調節するように配置した駆動部50と、車両が走行中の場合に、車両の加速または減速の状況で加速度センサーを用いて道路に対する車両の動的傾きの値を演算した後に、車両の動的傾きの値に基づいて車両の第1の静的傾きの値を演算し、車両が停車中の場合に、加速度センサー及び車両が配置する道路の道路勾配値を用いて車両の第2の静的傾きの値を演算した後に、演算した第1の静的傾きの値または第2の静的傾きの値に基づいてランプの前方に照射される光の方向を制御する制御部40と、を含む。【選択図】図1
