The headlight swivel control apparatus includes a first function of
obtaining road map data, current position information of a vehicle, and
width-direction-position information for determining a position of the
vehicle on a road on which the vehicle is driving in a width direction of
the road, a second function of determining a control start point on the
road on the basis of the road map data and the current position
information, a third function of determining, on the basis of the road
map data and the current position information, a width-direction distance
representing a distance between a centerline of the road and the vehicle,
a fourth function of calculating a target swivel angle depending on road
curvature data included in the road map data, and a fifth function
configured to start, when the vehicle reaches the control start point, to
perform a swivel control.
