To improve the illumination effect of a low beam while suppressing dazzling during ADB control.SOLUTION: A control device for controlling operation of a vehicle headlight has a variable light distribution-ON mode that, when there is an object in front of a vehicle, sets a dimming range NB corresponding to a position of the object within an illumination range of a high beam HB. When the variable light distribution-on mode is set, the control device sets luminosity of a partial range SG to first luminosity, wherein the partial range SG is within an irradiation range of a low beam LB that is a portion of the low beam LB in a vehicle width direction of the vehicle from a first virtual reference line parallel to the vehicle width direction to a prescribed position below the first virtual reference line. When the variable light distribution-on mode is not set, the control device sets the luminosity of the partial range SG to second luminosity, which is higher than the first luminosity. Then, the control device generates a control signal for operating the vehicle headlight on the basis of setting results for the dimming range NB and setting result for the luminosity of the specific range, and outputs the control signal to the vehicle headlight.SELECTED DRAWING: Figure 4

    【課題】ADB制御時の眩惑を抑えつつロービームによる照明効果の向上を図ること。【解決手段】車両用前照灯の動作を制御するための制御装置であって、車両の前方に対象物が存在する場合にはハイビームHBの照射範囲内に前記当該対象物の位置に応じた減光範囲NBを設定する可変配光オンモードを有し、ロービームLBの照射範囲内の一部範囲SGであって前記車両の車幅方向に平行な第1仮想基準線からその下方の所定位置までの一部分かつ前記ロービームLBの前記車幅方向の一部分である当該一部範囲SGの光度を、前記可変配光オンモードが設定された場合に第1光度に設定し、前記可変配光オンモードが設定されていない場合には前記第1光度よりも高い第2光度に設定し、前記減光範囲NBの設定結果及び前記特定範囲の前記光度の設定結果に基づいて前記車両用灯具を動作させるための制御信号を生成して前記車両用前照灯へ出力する、車両用前照灯の制御装置。【選択図】図4
