Abstract:
Provided is a headlight light distribution control device (ZHS) comprising: a detection unit (KE) which detects the positions of other vehicles (ZS, TS) existing in front of an own vehicle (JS) on the basis of an image of the other vehicles (ZS, TS); a first determination unit (KE1) which determines shielded light areas (SZS, STS) which are areas to be shielded from the light on the basis of the positions of the detected other vehicles (ZS, TS); a second determination unit (KE2) which determines a plurality of dimmed light areas (GZS(H), GZS(M), GTS(H), GTS(M)) which are areas close to the determined shielded light areas (SZS, STS) and are to have light amounts larger than light amounts in the shielded light areas (SZS, STS); an estimation unit (SU) which estimates the positions of drivers (US) in the other vehicles (ZS, TS); and a control unit (SE) which controls emission of the headlight (ZT) such that light amounts (IZS(M), ITS(M)) in dimmed light areas (GZS(M), GTS(M)) in one part which are of the plurality of the dimmed light areas (GZS(H), GZS(M), GTS(H), GTS(M)) and are closer to the estimated positions of the drivers (US) are smaller than light amounts (IZS(H), ITS(H)) in dimmed light areas (GZS(H), GTS(H)) in a part other than the dimmed light areas in the one part.
