Abstract
A control device of a vehicle lamp includes: a receiving section which receives an acceleration value usable to derive a tilt angle of a vehicle to a horizontal plane, wherein the tilt angle of the vehicle to the horizontal plane is represented as a total angle; and a control section which controls an optical axis adjustment of the vehicle lamp. The control section derives from the total angle a first and a second provisional vehicle posture angles based on a first and a second calculation method, respectively, corrects the first or second provisional vehicle posture angle so that a difference between the first and the second provisional vehicle posture angles becomes small, sets the corrected provisional vehicle posture angle to the vehicle posture angle, and outputs a control signal for instructing the optical axis adjustment of the vehicle lamp according to the vehicle posture angle.
