To provide a vehicular headlamp capable of securing front visibility by reducing glare given to a pedestrian and the preceding vehicle without providing a special detection mechanism for detecting a pedestrian, and a method for controlling the vehicular headlamp.SOLUTION: A vehicular headlamp includes a low beam irradiation part for irradiating light only to a downward irradiation regions (61, 71) lower than a cut-off line, an additional high beam irradiation part for irradiating light to a remote irradiation region upper than a selective irradiation area, and a control part for controlling light emission of the low beam irradiation part, an ADB irradiation part and the additional high beam irradiation part on the basis of position information showing the position of a traveling vehicle existing in front, and travel speed information showing a vehicle speed of an own vehicle. The top edge of the selective irradiation range (72) is the range of 0.7 to 1.5 degrees upward from a horizontal direction.SELECTED DRAWING: Figure 3
【課題】歩行者を検知する特別な検知機構を設けることなく歩行者および前方車に与えるグレアを低減し、前方視認性を確保することが可能な車両用前照灯および車両用前照灯の制御方法を提供する。【解決手段】カットオフラインより下方の下方照射領域(61,71)に対してのみ光を照射するロービーム照射部と、選択照射領域よりも上方の遠方照射領域に対して光を照射する付加的ハイビーム照射部を備え、前方に存在する走行中の車両の位置を示す位置情報および、自車両の車速を示す走行速度情報に基づいて、ロービーム照射部、ADB照射部および付加的ハイビーム照射部の発光を制御する制御部を備え、選択照射領域(72)の上端は水平方向から上方に0.7〜1.5度の範囲である車両用前照灯。【選択図】図3
