To provide a vehicle headlight device that prevents a driver and the like from feeling strange when switching the light radiation condition.SOLUTION: The vehicle headlight device includes vehicle headlights 20L, 20R that can radiate light independently onto a plurality of light distribution regions defined in the vehicle width direction; and a control unit 12 that acquires the horizontal position information of a vehicle at the front of own vehicle at predetermined time intervals, and that performs light distribution control per light distribution region depending on the position of the vehicle at the front. The vehicle headlight device has a light distribution region determination unit 121 that determines whether there are a plurality of light distribution regions to be switched from the turn-off state to turn-on state when the position of the vehicle at the front that the control unit 12 newly acquired is in the direction of the center line of a roadway nearer than the position of the vehicle at the front that the control unit 12 previously acquired; and a light distribution control unit 122 performs control so as to switch from the turn-off state to turn-on state gradually in order from a light distribution region corresponding to the position of the vehicle at the front that was previously acquired to a light distribution region corresponding to the position of the vehicle at the front that is newly acquired when there are a plurality of light distribution regions to be switched to the turn-on state.SELECTED DRAWING: Figure 1

    【課題】光照射状態の切り替え時における運転者等への違和感を軽減させる車両用前照灯装置を提供する。【解決手段】車幅方向に区分した複数の配光領域をそれぞれ別個独立に光照射可能な車両用前照灯20L、20Rと、自車両に対する前方車両の水平方向の位置情報を所定の時間間隔で取得し、前方車両の位置に応じて配光領域毎に配光制御を行う制御部12とを備える。制御部12が新規取得した前方車両の位置が、前回取得した前方車両の位置よりも走行路の中央線に近づく方向に位置する場合に、消灯状態から点灯状態に切り替える対象となる配光領域が複数存在するかを判定する配光領域判定部121と、点灯状態へ切り替える配光領域が複数存在する場合に、前回取得した方車両の位置に対応する配光領域から新規取得した前方車両の位置に対応する配光領域に向かって順に、段階的に消灯状態から点灯状態に切り替えるように制御する配光制御部122とを有する。【選択図】図1
