VEHICULAR LIGHTING APPARATUS
First Claim
Patent Images
1. A vehicular lighting apparatus, comprising:
- an irradiator comprising;
a main irradiation unit for radiating light ahead of an own vehicle; and
a support irradiation unit for supporting the main irradiation unit in the radiation of the light;
side-wall position direction detecting means for detecting a side-wall position direction indicating a position direction of a side wall of a tunnel, which is adjacent to a lane in which the own vehicle is traveling, with respect to the own vehicle while the own vehicle is traveling through the tunnel; and
side-wall irradiation control means for setting, when the side wall of the tunnel is positioned adjacent to the lane in which the own vehicle is traveling, a direction of the radiation of the light by the support irradiation unit, based on the side-wall position direction, so that an irradiation area irradiated by the irradiator becomes larger on a side of the side-wall position direction than an irradiation area irradiated by the main irradiation unit and controlling the support irradiation unit to radiate the light.

Abstract
While an own vehicle is traveling through the tunnel, a lighting ECU detects a side-wall position direction indicating a direction of a side wall of a tunnel T, which is adjacent to a lane in which the own vehicle is traveling, with respect to the own vehicle. The lighting ECU turns ON one of cornering lights respectively provided on a left side and a right side of the own vehicle, which is provided on the side-wall position direction.
