Abstract
A vehicle headlight control device that controls a light distribution of headlight, includes: an obtaining section that obtains a distance from a driver's vehicle to a forward vehicle and the position of a forward vehicle; and a light distribution control section that changes the light distribution of the headlight based on the position of the forward vehicle, and set an illumination region, and a non-illumination region provided in a vicinity of the forward vehicle so as to include the forward vehicle and a margin distance from an end of a body of the forward vehicle. The light distribution control section determines a distance, in a vehicle width direction, between: a boundary between the illumination region and the non-illumination region; and each of left and right lateral ends of the forward vehicle, such that the greater the distance is, the less the distance in the vehicle width direction is.
