PROBLEM TO BE SOLVED: To provide a vehicular headlamp control unit capable of upgrading perceptibility of an area ahead of a vehicle by controlling light distribution of headlamps on the basis of an inter-vehicle distance from an own vehicle to a forward vehicle.SOLUTION: A vehicular headlamp control unit that controls light distribution of headlamps includes an acquirer that acquires the position of a forward vehicle existing ahead of an own vehicle and an inter-vehicle distance from the own vehicle to the forward vehicle, and a light distribution controller that changes light distribution of the headlamps on the basis of the position of the forward vehicle and designates a light irradiated area and a non-light irradiated area which has a predetermined spacing from an end of a vehicle body within a space around the forward vehicle including the forward vehicle. The light distribution controller determines spacings in a vehicle width direction from the boundary between the light irradiated area and non-light irradiated area to the left and right edges of the forward vehicle so that the spacings will be diminished as the inter-vehicle distance gets larger.SELECTED DRAWING: Figure 3
【課題】自車両から前方車両までの車間距離に基づいて前照灯の配光を制御することによって、車両前方の視認性を向上させることができる車両用前照灯制御装置を提供する。【解決手段】前照灯の配光を制御する車両用前照灯制御装置であって、自車両の前方に存在する前方車両の位置および自車両から前方車両までの車間距離を取得する取得部と、前方車両の位置に基づいて前照灯の配光を変化させ、光照射領域と、前方車両を含む前方車両の周囲に、車体端から所定の間隔を有した非光照射領域とを、設定する配光制御部とを備え、配光制御部が、光照射領域と非光照射領域との境界と、前方車両の左右側端との、車幅方向の間隔を、車間距離が大きくなるにつれて小さくするように決定することを特徴とする。【選択図】図3
