Patent ID: 7503677

Claim:
A headlight control apparatus for a vehicle having a headlight, the headlight control apparatus comprising: a direction control device for controlling an irradiation direction of the headlight; and a direction calculation device for calculating a control direction in which the headlight is controlled to irradiate a beam, wherein the direction calculation device includes: a first calculation section which calculates a first irradiation direction as the control direction with a first method in a first period; a second calculation section which calculates a second irradiation direction with a second method different from the first method; and a transition calculation section which, in a transition control period subsequent to the first period, uses the control direction calculated in the past and the second irradiation direction calculated by the second calculation section for calculating a transition irradiation direction between the control direction and the second irradiation direction to be used as the control direction so that the control direction to be used can be gradually changed to the second irradiation direction.
