Lamp control system and control device

摘要

A lamp control system includes: a lamp configured to form a light distribution pattern ahead of a vehicle using a non-illumination region forming unit, wherein the light distribution pattern includes a non-illumination region, and the illumination region includes at least one longitudinal cutoff line; a detector configured to detect a front vehicle in front of the vehicle; an information acquiring unit configured to acquire a displacement direction and a displacement speed of the front vehicle; and a light distribution controller configured to control the light distribution pattern using the non-illumination region forming unit such that the front vehicle is positioned in the non-illumination region. When the front vehicle is approaching the longitudinal cutoff line, the light distribution controller controls the light distribution pattern based on the displacement direction and the displacement speed to increase an interval between the longitudinal cutoff line and the front vehicle.

1. A lamp control system comprising:
a lamp configured to form a light distribution pattern ahead of a vehicle using a non-illumination forming unit, wherein the light distribution pattern comprises an illumination region and a non-illumination region, and the illumination region comprises at least one longitudinal cutoff line at a boundary between the illumination region and the non-illumination region; a detector configured to detect a front vehicle in front of the vehicle; an information acquiring unit configured to acquire a displacement direction and a displacement speed of the front vehicle; and a light distribution controller configured to control the light distribution pattern using the non-illumination region forming unit such that the front vehicle detected by the detector is positioned in the non-illumination region with a predetermined interval between the longitudinal cutoff line and the front vehicle, wherein when the front vehicle is approaching the longitudinal cutoff line, the light distribution controller is configured to control the light distribution pattern based on the displacement direction and the displacement speed so as to increase the predetermined interval between the longitudinal cutoff line and the front vehicle by a first predetermined value, and wherein when the front vehicle is moving away from the longitudinal cutoff line, the light distribution controller is configured to control the light distribution pattern based on the displacement direction and the displacement speed so as to decrease the predetermined interval between the longitudinal cutoff line and the front vehicle by a second predetermined value.
