PROBLEM TO BE SOLVED: To make it possible to accurately control the optical axis of a headlight even during acceleration or deceleration.SOLUTION: An ECU 20 detects acceleration of a vehicle 5, calculates a pitch angle of the vehicle 5 on the basis of the detected acceleration using a predetermined computation method using the acceleration. The computation method varies at least depending on whether the vehicle 5 is accelerating or decelerating. The ECU 20 controls a headlight 10 mounted on the vehicle 5 so that an optical axis of the headlight 10 faces a direction in response to the calculated pitch angle.SELECTED DRAWING: Figure 1

    【課題】加速中か減速中かにかかわらず前照灯の光軸を精度良く制御できるようにする。【解決手段】ECU20は、車両5の加速度を検出し、その検出した加速度に基づき、その加速度を用いた所定の演算方法を用いて、車両5のピッチ角を算出する。上記演算方法は、少なくとも、車両5が加速中か減速中かによって異なる。ECU20は、車両5に搭載された前照灯10を、その光軸が上記算出されたピッチ角に応じた方向を向くように制御する。【選択図】図1
