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 1 comprises a light emission part (a left-side pattern emission lighting fixture 41) which emits light to a light distribution area (an emission pattern light distribution area 16) outside a running lane on which a vehicle travels in an emission pattern Lp in which bright areas a1 and dark areas a2 are alternately repeated, control means (a light fixture control ECU 40) that controls lighting-up and a non-lighting-up of the light emission part, and sensing means 90 that senses presence of a pedestrian 15 in the light distribution area, where the control means lights up the light emission part on the basis of a sensing result from the sensing means. In one aspect thereof, the sensing means produces sensing output (a person identification signal Spi2) showing that the degree of certainty of a pedestrian, which is a degree at which a sensed object is likely a pedestrian, is a second degree of certainty of a pedestrian lower than a first degree of certainty of a pedestrian which is a degree at which a pedestrian protection brake is activated, and the control means lights up the light emission part in accordance with the sensing output.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Lpで走行車道外側の配光領域(照射パターン配光領域16)に光を照射する光照射部(左側パターン照射灯具41)と、光照射部の点灯と非点灯を制御する制御手段(灯具制御ECU40)と、配光領域に歩行者15の存在を検知する検知手段90と、を備え、制御手段は、検知手段の検知結果に基づいて光照射部を点灯する、車両用前照灯装置1。その一態様では、検知手段は、検知対象物が歩行者であるらしい度合いである歩行者確度が歩行者保護ブレーキを作動させる程度である第1の歩行者確度よりも低い第2の歩行者確度である旨の検知出力(人識別信号Spi2)を発し、制御手段が検知出力に応じて光照射部を点灯する。【選択図】図2
