Patent ID: 7791459

Claim:
A vehicle light control system comprising: a light device emitting an illumination light around an object vehicle on which said vehicle light control system is mounted; an information obtaining device obtaining integrated information including at least vehicle information indicating a behavior of said object vehicle; a control unit including an illumination target candidate setting function of setting a plurality of illumination target candidates which a driver of said object vehicle should pay attention to on the basis of said integrated information, said plurality of said illumination target candidates being given a risk degree respectively, and a determination function of selecting an illumination target from among said plurality of said illumination target candidates on the basis of said risk degree; and an actuator device controlling said light device such that said illumination light is emitted in a direction of travel of said object vehicle and in a direction of said illumination target different from the direction of travel; wherein said information obtaining device includes a vehicle information obtaining device obtaining said vehicle information, and a direction-change-information obtaining device obtaining direction change information including at least information indicating a new direction to which said vehicle can change, said integrated information being constituted by said vehicle information and said lane change information, said illumination target candidate setting function determines said new direction as one of said illumination target candidates when said integrated information indicates that said object vehicle is intending to change directions; and said direction-change-information obtaining device includes an obstacle detecting function of detecting an obstacle existing on said driving road, and an avoidable area detecting function of detecting an avoidable area to avoid said obstacle, and is configured to set said avoidable area detected by said avoidable area detecting function as said new direction.
