FLUX DISTRIBUTION CONTROL SYSTEM OF LIGHTING FIXTURE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a flux distribution control system of a lighting fixture for a vehicle capable of properly controlling an irradiating area constantly in accordance with the forwarding direction of the vehicle by avoiding an unnecessary change of the irradiation area.

SOLUTION: A lamp control circuit of this flux distribution control system of the lighting fixture for the vehicle forms a control map to decide a swivel angle of a head light 10 in accordance with road information input by a step 110 by inputting the road information displaying a shape of a travelling road slightly in front of the vehicle from a navigation control circuit 31 by a step 108. Thereafter, the optical axis direction of the head light 10 is controlled so as to be the computed swivel angle by a step 116 by inputting a steering angle from a steering angle sensor 22 by a step 112 and computing the swivel angle in correspondence with the input steering angle by a step 114 in accordance with the control map.
