To provide a light distribution control technique that can reduce glare toward a vehicle ahead of an own vehicle when the orientation of the own vehicle changes in a pitch direction.SOLUTION: A device is configured to control a vehicle lamp fitting designed to selectively emit light in accordance with the position of a vehicle existing around and ahead of an own vehicle. The device includes a light distribution range setting unit, a light distribution range correction unit, and a light distribution control unit. The light distribution range setting unit is configured to set a light irradiation range by the vehicle lamp fitting such that a certain range corresponding to the position of the vehicle ahead is defined as a non light irradiation range where no light is emitted by the vehicle lamp fitting. When the orientation of the own vehicle changes in a pitch direction, the light distribution range correction unit is configured to correct the non light irradiation range by using a correction amount based on a physical amount of the direction of orientation change and the orientation change so as to expand the non light irradiation range in the opposite direction to the direction of orientation change. The light distribution control unit is configured to generate and output a light distribution control signal for controlling the operation of the vehicle lamp fitting in accordance with the non light irradiation range corrected by the light irradiation correction unit and the light irradiation range.SELECTED DRAWING: Figure 5
