To suppress peeping inside a vehicle and to suppress unnecessary restriction of incidence of external light into the vehicle.SOLUTION: A dimming system 41 for a vehicle is provided in a vehicle 20 in which a dimming member 1 is arranged at portions 23A, 23B, 24 on which external light is incident, and comprises: a distance information acquisition unit 31 that acquires distance information between another vehicle existing around a vehicle 20 and the vehicle 20; a drive control unit 36 that changes the transmittance of the dimming member 1 based on the distance information; a storage unit 32 that stores a determination reference value of the distance information; a comparison unit 33 that compares the determination reference value with the distance information acquired by the distance information acquisition unit 31; and a height measurement unit 35 that measures the height of other vehicles. Based on the comparison result of the comparison unit 33, the drive control unit 36 reduces the transmittance of the dimming member 1 when the distance information acquired by the distance information acquisition unit 31 is equal to or less than the determination reference value. The drive control unit 36 locally changes the transmittance of the dimming member 1 based on the measurement result of the height measurement unit 35.SELECTED DRAWING: Figure 2
【課題】車内の覗き見を抑制するとともに、不必要に車内への外光の入射を制限してしまうのを抑制することを目的とする。【解決手段】車両用調光システム41は、外光が入射する部位23A、23B、24に調光部材1が配置された車両20に設けられるており、車両20の周囲に存在する他の車両と車両20との距離情報を取得する距離情報取得部31と、距離情報に基づいて、調光部材1の透過率を変化させる駆動制御部36と、距離情報の判定基準値を記憶する記憶部32と、判定基準値と距離情報取得部31で取得した距離情報とを比較する比較部33と、他の車両の高さを計測する高さ計測部35とを備え、駆動制御部36は、比較部33の比較結果に基づいて、距離情報取得部31で取得した距離情報が、判定基準値以下の場合、調光部材1の透過率を低減し、駆動制御部36は、高さ計測部35の計測結果に基づいて、調光部材1の透過率を局所的に変化させる。【選択図】図2
