The invention relates to a light projection control apparatus and method for a vehicle, and a light projection system for a vehicle. The purpose of the present invention is to obtain a vehicle light projection control device capable of improving an anti-glare effect for a vehicle driver when a reflector is included within a light projection range of a light projection mechanism mounted on a vehicle. A position detection unit (52) detects a reference position, which is the position of a reflector with respect to a vehicle (1), included in an image captured in the direction of travel of the vehicle (1). A position estimation unit (53) estimates the relative position of the reflector with respect to the traveling vehicle (1) on the basis of position information relating to the reference position and travel information of the vehicle (1). A light reduction control unit (54) performs light reduction control on the headlamp unit (2) so as to reduce light projected in a range corresponding to the relative position in a light projection range of the headlamp unit (2).

    本发明涉及车辆用投光控制装置及方法、车辆用投光系统。得到一种车辆用投光控制装置,在搭载于车辆的投光机构的投光范围内包含反射体的情况下,能够提高针对车辆驾驶员的防眩效果。位置检测部(52)检测对车辆(1)的行进方向进行拍摄而得到的影像内包含的反射体相对于车辆(1)的位置即基准位置。位置推断部(53)基于与上述基准位置相关的位置信息以及车辆(1)的行进信息,推断反射体相对于行进的车辆(1)的相对位置。减光控制部(54)对前照灯单元(2)进行减光控制,以便对向前照灯单元(2)的投光范围中的与上述相对位置对应的范围的投光进行减光。
