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 detector and adjusts a position of an optical axis of a vehicle lighting fixture, with higher accuracy.SOLUTION: Irradiation controllers 228L and 228R include: receivers 228L1 and 228R1 for receiving an inclination angle of a vehicle 300 with respect to a horizontal plane from an inclination detector; controllers 228L2 and 228R2 configured to generate a control signal for instructing a vehicle lighting fixture to adjust an optical axis of the vehicle lighting fixture in response to change of the inclination angle, while the vehicle is stopped, and avoiding generation of the control signal or generate a second control signal for instructing the vehicle lighting fixture to maintain the optical axis of the vehicle lighting fixture in response to change of the inclination angle, while the vehicle travels; and transmitters 228L3 and 228R3 for transmitting the control signal to a leveling controller 236 of the vehicle lighting fixture. |
