To provide a vehicle headlight optical axis control device capable of shortening a time until optical axis control based on an accurate vehicle angle can be performed.SOLUTION: A controller uses output of a gyro sensor to obtain a pitch angle of a vehicle, and when an amount of change in the pitch angle is smaller than a predetermined reference value, calculates gravity acceleration components corresponding to at least a longitudinal direction and a vertical direction of the vehicle using the pitch angle, removes each of the gravity acceleration components from acceleration corresponding to the longitudinal direction and the vertical direction of the vehicle obtained by using the output of an acceleration sensor, and controls an optical axis of a headlight using the acceleration corresponding to the longitudinal direction and the vertical direction of the vehicle after removing each of the gravity acceleration components.SELECTED DRAWING: Figure 8
【課題】精度の良い車両角度に基づく光軸制御をできるようになるまでの時間を短縮することのできる車両用前照灯の光軸制御装置を提供する。【解決手段】コントローラは、ジャイロセンサの出力を用いて車両のピッチ角度を求め、ピッチ角度の変化量が所定の基準値よりも小さい場合に、ピッチ角度を用いて車両の少なくとも前後方向及び上下方向の各々に対応する重力加速度成分を算出し、加速度センサの出力を用いて求まる車両の前後方向及び上下方向の各々に対応する加速度の各々から各重力加速度成分を除去し、各重力加速度成分を除去後の車両の前後方向及び上下方向の各々に対応する加速度を用いて前照灯の光軸を制御する。【選択図】図8
