To preset an appropriate dimming range even if a preceding vehicle, etc. is a two-wheel vehicle.SOLUTION: A device for controlling a light irradiation range and a dimming range by means of a pair of vehicular lamp fixtures set up on the vehicle front side includes: a sensor for detecting a left end angle θL and a right end angle θR which are relative angles with a prescribed position as a reference with respect to a position of a target; and a controller which presets the light irradiation range and the dimming range based on the left end angle θL and the right end angle θR and supply a control signal for executing light irradiation in accordance with the light irradiation range and the dimming range to the pair of vehicular lamp fixtures. The controller detects that the target is a two-wheel vehicle when a difference θOP between the left end angle θL and the right end angle θR is smaller than a threshold provided by dividing the left end angle θL or the right end angle θR by a natural number N (therein, N≥2) and sets the light irradiation range and the dimming range based on position relation, on the assumption of the two-wheel vehicle.SELECTED DRAWING: Figure 3

    【課題】先行車両等が二輪車両であっても適切な減光範囲を設定すること。【解決手段】車両前方に設置される一対の車両用灯具による光照射範囲及び減光範囲を制御するための装置であって、物標の位置について所定位置を基準とした相対的な角度である左端角度θL及び右端角度θRを検出するセンサと、左端角度θL及び右端角度θRに基づいて光照射範囲及び減光範囲を設定して当該光照射範囲及び減光範囲に応じた光照射を実行するための制御信号を一対の車両用灯具へ供給するコントローラと、を含み、コントローラは、左端角度θLと右端角度θRとの差分θOPが、左端角度θL又は右端角度θRを自然数N(ただし、N≧2)で除算して得られる閾値より小さい場合に物標が二輪車両であることを検出し、当該二輪車両を前提とした位置関係に基づいて光照射範囲及び減光範囲を設定する。【選択図】図3
