PROBLEM TO BE SOLVED: To provide a technique capable of performing automatic leveling control, which acquires an inclination angle of a vehicle with respect to a horizontal plane from an inclination detecting device and adjusts a position of an optical axis of a vehicle lighting fixture, with higher accuracy.SOLUTION: Irradiation control parts 228L and 228R include: receiving parts 228L1 and 228R1 for receiving an inclination angle of a vehicle 300 with respect to a horizontal plane from an inclination detecting device; control parts 228L2 and 228R2 configured to generate a control signal for instructing adjustment for a position of an optical axis of the vehicle lighting fixture in response to change of the inclination angle, during stopping of the vehicle, and avoid generation of the control signal or generate a control signal for instructing the vehicle lighting fixture to maintain the position of the optical axis in response to change of the inclination angle, during traveling of the vehicle; and transmitting parts 228L3 and 228R3 for transmitting the control signal to a leveling control part 236 of the vehicle lighting fixture.SELECTED DRAWING: Figure 2 |
