PROBLEM TO BE SOLVED: To reduce incongruity imparted to a user accompanied by the switching of a light distribution pattern while making compatible both the suppression of a glare and the improvement of visibility, in a light distribution system of a vehicle headlamp.SOLUTION: A control unit 20 decides a light distribution pattern on the basis of information indicating a status of a vehicle front, and controls lighting states of respective radiation parts 11 to 13 according to the light distribution pattern. When an ADB light distribution pattern is selected, the control unit 20 adjusts a turning angle of the ADB beam radiation part 12 by controlling a drive part 15 on the basis of the information indicating the status of the vehicle front. Then, when switching to a traveling light distribution pattern from the ADB light distribution pattern is decided, the control unit 20 permits the lighting of the traveling beam radiation part 13 on condition that the rotation angle of the ADB beam radiation part 12 exists within an angle of a prescribed range from the vehicle front. |
