HEADLAMP LIGHT DISTRIBUTION CONTROL DEVICE

摘要

In a headlamp light distribution control device, a light source configured by a pair of lamps mounted in a forward vehicle is extracted from an image of the forward vehicle if a distance to the forward vehicle is less than a predetermined value, and the number of the extracted light sources is judged. When the number of the extracted light sources is two, an irradiation direction of a headlamp is controlled such that a shielded area is set in an irradiation area to prevent an area including the lamp of the forward vehicle from being irradiated. When the number of the extracted light sources is one, the irradiation direction is controlled such that a shielded area is set in the irradiation area to have a margin in right and left directions larger than the shielded area set when the number of the extracted light sources is two.

主权项

1. A headlamp light distribution control device for a vehicle, the headlamp light distribution control device comprising:
an image acquisition unit configured to acquire an image of a forward area which is ahead of an own vehicle; an extraction unit configured to extract a forward vehicle from the image of the forward area acquired by the image acquisition unit; a distance acquisition unit configured to acquire a distance between the own vehicle and the forward vehicle; a judgment unit configured to
extract a light source configured by a pair of lamps mounted in the forward vehicle from the image of the forward vehicle extracted by the extraction unit if the distance from the own vehicle to the forward vehicle acquired by the distance acquisition unit is less than a predetermined value, andjudge the number of the extracted light sources; and a control unit configured to
set, when the judgment unit judges that the number of the extracted light sources is two, a shielded area in an irradiation area of a headlamp of the own vehicle so as to prevent an area including the lamp of the forward vehicle from being irradiated, andset, when the judgment unit judges that the number of the extracted light sources is one, a shielded area in the irradiation area of the headlamp of own vehicle so as to have a margin in right and left directions larger than the shielded area set when the number of the extracted light sources is two.
