Abstract
In a headlight optical-axis control device, a controlleris configured to: calculate vehicle angles indicating tilt angles of a vehicle relative to a road surface, on the basis of ratios, each being a ratio of a difference between a reference acceleration in a longitudinal direction and a signal indicating an acceleration in the longitudinal direction detected during traveling of the vehicle, to a difference between a reference acceleration in a perpendicular direction and a signal indicating an acceleration in the perpendicular direction detected during traveling of the vehicle by an acceleration sensor; calculate a plot of the calculated vehicle angles thereby to derive a vehicle angle corresponding to a case where a change of the acceleration in the longitudinal direction is zero; and generate a signal for controlling the optical axes of headlightsL andR on the basis of the derived vehicle angle.
