Abstract:
The present invention comprises a leveling actuator (114) which is for optical axis adjustment and is provided in a head lamp (110). This leveling control device (200) controls the leveling actuator (114). An operation unit (210) outputs a control signal (SCTRL) that changes according to control characteristics defined by a broken line with respect to a slope (θ) of a vehicle body in the longitudinal direction of the vehicle body. An output stage (220) generates an output voltage (SOUT) in response to the control signal (SCTRL).
