To provide an optical axis control device which can accurately calculate the vehicle body angle to road surface φ for auto-leveling control.SOLUTION: An angle calculation unit 15 calculates the vehicle body angle to road surface φ of a vehicle 1 on the basis of the ratio (ΔGz/ΔGx) of the difference value ΔGz between the deceleration-time vertical direction acceleration speed Gz2 and the acceleration-time vertical direction acceleration speed Gz1 to the difference value ΔGx between the deceleration-time front-rear direction acceleration speed Gx2 and the acceleration-time front-rear direction acceleration speed Gx1. The absolute value |α1| of the travel acceleration speed α1 at the detection of the acceleration-time acceleration speed G1 used for the calculation of the vehicle body angle to road surface φ is equivalent to the absolute value |α2| of the travel deceleration speed α2 at the detection of the deceleration-time acceleration speed G2 used for the calculation of the vehicle body angle to road surface φ. The magnitude |G1| of the vector sum indicating the acceleration-time acceleration speed G1 used for the calculation of the vehicle body angle to road surface φ is equivalent to the magnitude |G2| of the vector sum indicating the deceleration-time acceleration speed G2 used for the calculation of the vehicle body angle to road surface φ.SELECTED DRAWING: Figure 1

    【課題】オートレベリング制御用の対路面車体角度φを正確に算出することができる光軸制御装置を提供する。【解決手段】角度算出部15は、減速時上下方向加速度Gz2と加速時上下方向加速度Gz1との差分値ΔGzと、減速時前後方向加速度Gx2と加速時前後方向加速度Gx1との差分値ΔGxとの比(ΔGz/ΔGx)に基づき、車両1の対路面車体角度φを算出する。対路面車体角度φの算出に用いられる加速時加速度G1の検出時における走行加速度α1の絶対値|α1|は、対路面車体角度φの算出に用いられる減速時加速度G2の検出時における走行減速度α2の絶対値|α2|と同等である。対路面車体角度φの算出に用いられる加速時加速度G1を示すベクトル和の大きさ|G1|は、対路面車体角度φの算出に用いられる減速時加速度G2を示すベクトル和の大きさ|G2|と同等である。【選択図】図1
