To maintain the formation accuracy of a light distribution pattern, while suppressing complication of a constitution of a vehicular lighting fixture system.SOLUTION: A vehicular lighting fixture system 1 comprises: an imaging unit 12; a luminance analysis unit 14 which detects the luminance of a plurality of individual regions aligned in front of an own vehicle; an illuminance setting unit 42 which determines an illuminance value of light to be radiated to each individual region, on the basis of a detection result of the luminance analysis unit 14; a light source unit 10; and a light source control unit which controls the light source unit 10 according to the illuminance value determined by the illuminance setting unit 42. The light source control unit 20 controls the light source unit 10 so as to periodically form a reference light distribution pattern containing, at least at one part, a fixed illuminance region not depending on the illuminance value determined by the illuminance setting unit 42. The illuminance setting unit 42 determines the illuminance value on the basis of a reference detection result containing the detection result of the luminance analysis unit 14 obtained under formation of the reference light distribution pattern, and updates the illuminance value when a new reference detection result is obtained.SELECTED DRAWING: Figure 1

    【課題】車両用灯具システムの構成の複雑化を抑制しながら配光パターンの形成精度を維持する。【解決手段】車両用灯具システム1は、撮像部12と、自車前方に並ぶ複数の個別領域の輝度を検出する輝度解析部14と、輝度解析部14の検出結果に基づいて各個別領域に照射する光の照度値を定める照度設定部42と、光源部10と、照度設定部42が定める照度値に基づいて光源部10を制御する光源制御部と、を備える。光源制御部20は、照度設定部42が定める照度値に依存しない固定照度領域を少なくとも一部に含む基準配光パターンを定期的に形成するよう光源部10を制御し、照度設定部42は、基準配光パターンの形成下で得られる輝度解析部14の検出結果を含む基準検出結果に基づいて照度値を定め、新たな基準検出結果が得られると照度値を更新する。【選択図】図1
