Abstract
There is provided a control device for controlling a vehicle lamp. The device includes: a receiver configured to receive an output value from an inclination sensor; and a controller configured to control an optical axis of the vehicle lamp based on a vehicle attitude angle that is an inclination angle of the vehicle with respect to a road surface. The controller is configured to control the optical axis in a first optical axis control mode or a second optical axis mode, wherein an optical axis angle of the optical axis is adjusted in accordance with the vehicle attitude angle in the first optical axis mode, and the second optical axis control mode is different from the first optical axis control mode. The controller controls the optical axis in the second optical axis control mode, when the vehicle attitude angle is not included in a predetermined range.
