  • Publication number: 20190248276
    Abstract: A vehicle illumination system provided to a vehicle capable of traveling in an autonomous driving mode includes: an illumination unit configured to emit a light pattern toward an outside of the vehicle; and an illumination controller configured to control the illumination unit to irradiate the light pattern to a predetermined position. When the vehicle changes a traffic lane from a first traffic lane to a second traffic lane, the illumination controller: controls the illumination unit to irradiate the light pattern on a road surface between a first other vehicle traveling on the second traffic lane and a second other vehicle which is a following vehicle of the first other vehicle; and changes a length of the light pattern, depending on an interval between the first other vehicle and the second other vehicle.
