Abstract: A rear-road surface illumination apparatus is provided which includes: an avoidance determiner 30 to determine whether to provide a display to induce a following vehicle to avoid a vehicle, on the basis of vehicle information; and a controller 9 to cause an illumination light 10 to illuminate a rear road surface with light having illumination information that induces the following vehicle to avoid the vehicle when the avoidance determiner 30 determines to provide a display to induce the following vehicle to avoid the vehicle. Therefore, the rear-road surface illumination apparatus can indicate the existence of the vehicle to the following vehicle, to give the existence of the vehicle prominence, and can also make it easy to notify the driver of the following vehicle about what the driver of the vehicle desires the driver of the following vehicle to do.

Abstract: Because a road surface illumination apparatus is configured so as to include a vehicle state detector 3 configured to detect the traveling direction of a vehicle on the basis of vehicle information acquired by a vehicle information acquisition unit 2, and an illumination pattern selector 4 to select an illumination pattern expressing the traveling direction detected by the vehicle state detector 3 from among illumination patterns held therein and provided for traveling directions, and to cause an illumination device 7 to illuminate at least a road surface in a direction different from the traveling direction with the selected illumination pattern, the road surface illumination apparatus can provide a notification of the traveling direction of the vehicle intuitively to persons outside the vehicle who are existing in the direction other than the traveling direction.

Abstract: Because a road surface illumination apparatus is configured so as to include a vehicle motion predictor 2 to predict the motion which a vehicle is going to perform from now on in accordance with vehicle information acquired by a vehicle information acquisition unit 1, and a light animation setting unit 3 to set a light animation expressing the motion predicted by the vehicle motion predictor 2, and to cause an illumination device 4 to illuminate a road surface with the animation before the vehicle performs the motion, the road surface illumination apparatus can intuitively notify the motion which the vehicle is going to perform from now on to persons outside the vehicle.
