Abstract
A control device for a vehicle lamp including an ECU configured to: i) receive a sensor signal and derive a total angle; ii) retain an initial set value of the vehicle posture angle, the initial set value being acquired in an initialization process; iii) retain a reference value of the vehicle posture angle, adjust an optical axis angle of the vehicle lamp in response to a change amount of a total angle during a stop of the vehicle, and retain a sum of the change amount of the total angle and the reference value of the vehicle posture angle as a new reference value; iv) not adjust the optical axis angle in response to a change amount of a total angle during traveling of the vehicle; and v) perform a predetermined reset process when a reset signal is received.
