CONTROL DEVICE FOR VEHICLE LAMP AND VEHICLE LAMP SYSTEM

There is provided a control device for controlling a vehicle lamp (210). The device includes: a receiver (102) configured to receive an output value from an inclination sensor (110); and a controller (104) configured to control an optical axis (O) of the vehicle lamp (210) based on a vehicle attitude angle (¸v) that is an inclination angle of the vehicle with espect to a road surface. The controller (104) 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 (¸o) of the optical axis is adjusted in accordance with the vehicle attitude angle (¸v) in the first optical axis mode, and the second optical axis control mode is different from the first optical axis control mode. The controller (104) controls the optical axis in the second optical axis control mode, when the vehicle attitude angle (¸v) is not included in a predetermined range (R1, R1').
