Abstract
A leveling controller (ECU) calculates a pitch angle based on a vehicle height value of a vehicle and controls an irradiation direction of a vehicle lamp. The leveling controller includes a vehicle height value initialization unit for initializing the detected vehicle height value, a determination unit for determining whether initialization by the vehicle height value initialization unit has been made, and a leveling angle setting unit for setting the leveling angle of the vehicle lamp based on the initialized vehicle height value or setting the leveling angle to a predetermined leveling angle, in accordance with the result of determination by the determination unit. An aiming device is arranged to perform aiming adjustment on the vehicle lamp in which the leveling angle is set by the leveling angle setting unit.
