To provide a vehicular headlight device that can suppress a driver from overlooking a pedestrian even under an adverse condition such as the nighttime, and the nighttime and a rainy weather.SOLUTION: A vehicular headlight device comprises a light emission part 4 that emits light to a light distribution area 16 in a vehicle 2 in an emission pattern Pf in which bright areas a1 and dark areas a2 are alternately repeated, where the light emission part 4 emits light so that the emission pattern Pf is moved along a travelling direction of the vehicle 2. In one aspect thereof, the light emission part 4 comprises a changing part 42 that changes a speed at which the emission pattern Pf is moved (a speed of a moving speed signal Fvs) in accordance with a vehicle speed of the vehicle 2 (a vehicle speed of a vehicle speed signal Vss), where the changing part 42 makes a speed at which a scene viewed from the vehicle 2 changes match a speed at which the emission pattern Pf is moved, in accordance with the vehicle speed (the vehicle speed of the vehicle speed signal Vss).SELECTED DRAWING: Figure 2
【課題】夜間や夜間でかつ雨天であるといった悪条件の下でも運転者による歩行者の見落としを改善できる車両用前照灯装置を提供すること。【解決手段】明領域a1と暗領域a2が交互に繰り返される照射パターンPfで車両2における配光領域16に光を照射する光照射部4を備え、光照射部4は、照射パターンPfを車両2の進行方向に沿って流すように照射する車両用前照灯装置。その一態様では、光照射部4は、車両2の車速(車速信号Vssの車速)に応じて照射パターンPfを流す速度(流れ速度信号Fvsの速度)を変える変更部42を備え、また、変更部42は、車速(車速信号Vssの車速)に応じて車両2から見た風景が流れる速度と照射パターンPfを流す速度とを一致させる。【選択図】図2
