Abstract
At the time of lane change of the own vehicle, a light pattern, which is a pattern in which three partial projection regions of a predetermined shape are arranged in a direction extending from the own vehicle to the lane side of the lane change destination, is projected from the lamp of the own vehicle in a direction extending from the own vehicle to the lane side of the lane change destination. Further, by reducing the number of partial projection regions of a predetermined shape included in the light pattern at the timing at which the lane change has progressed, the length of the light pattern is made shorter than the timing at which the lane change starts.
Claims4
A lamp control method for a vehicle, the lamp control method comprising:
- projecting, at a time of lane changing of the vehicle that is made by a driver, a light pattern from a lamp of the vehicle onto a road surface in a direction extending from the vehicle to a side of a lane to which the lane changing is to be performed;
- determining, based on information from a sensor of the vehicle, whether the light pattern protrudes from the lane to which the lane changing is to be performed;
- calculating an amount of protrusion of the light pattern in response to the determination that the light pattern protrudes from the lane to which the lane changing is to be performed;
- and
- shortening a length of the light pattern by reducing the number of partial projection regions with a predetermined shape included in the light pattern or by reducing a size of the entire light pattern, according to the calculated amount of protrusion, at a timing at which the lane changing progresses, as compared to at a timing at which the lane changing starts.
