摘要： A lighting ECU determines whether or not a road sign relating to an urban area or a residential area is detected, while it is performing an automatic high beam control. When the detected road sign is a road sign indicating a start point of the urban area or of the residential area, the lighting ECU terminates the automatic high beam control, and maintain a light distribution pattern to a pattern corresponding to low beam. The lighting ECU restarts the automatic high beam control, when the detected road sign is a road sign indicating an end point of the urban area or of the residential area.
