Claim:
A headlight swivel control apparatus for laterally controlling a swivel angle of a headlight of a vehicle comprising: a first function of obtaining road map data, current position information indicating a current position of said vehicle in said road map data, and width-direction-position information for determining a position of said vehicle on a road on which said vehicle is driving in a width direction of said road; a second function of determining a control start point on said road on the basis of said road map data and said current position information; a third function of determining, on the basis of said road map data and said current position information, a width-direction distance representing a distance between a centerline of said road and said vehicle; a fourth function of calculating a first target swivel angle depending on road curvature data included in said road map data, said road curvature data indicating a curvature of said road ahead of said vehicle; and a fifth function configured to start, when said vehicle reaches said control start point, to perform a first swivel control in order to cause said swivel angle of said headlight to approach to said first target swivel angle.
