VEHICULAR LIGHT DISTRIBUTION CONTROL SYSTEM AND VEHICULAR LIGHT DISTRIBUTION CONTROL METHOD

摘要

A vehicular light distribution control system (100) which controls a light distribution of headlights (3) includes a vehicle detecting part (10) which detects an anterior vehicle driving in front of an occupant's vehicle, an unirradiated region setting part (12) which sets a region where the anterior vehicle detected by the vehicle detecting part (10) exists as an unirradiated region, a vehicle motion estimating part (13) which estimates an ensuing motion of the anterior vehicle detected by the vehicle detecting part (10), and an unirradiated region adjusting part (14) which adjusts a size of the unirradiated region set by the unirradiated region setting part (12) depending on an estimated result of the vehicle motion estimating part (13).
