‐車両用照明(特にヘッドライト、テールライトおよびサイドマーカランプ)の切換状態:所定の閾値を下回ると照明が接続され、所定の閾値を上回ると照明は遮断される。
‐電気的に切換可能または制御可能な機能素子が装備された合わせガラスの領域の透過特性。このガラス板領域は、ガラス板の上側1/3に設けられた、特に切換可能または制御可能な(陰影帯としても知られる)防眩部である。この切換状態は、周辺光の絶対量に応じて制御可能である、あるいは複数のフォトダイオードまたは光センサ素子による場所に依存した測定により得られる太陽の位置に応じても制御可能である。特に太陽の位置が低いときに、防眩部が必要になる。制御可能な機能素子は、例えばSPD素子(suspended particle device)またはLC素子(liquid crystal)またはエレクトロクロミック素子であってよい。
‐車両内室における表示エレメント、例えばLED表示エレメントまたはOLED表示エレメントの輝度(明るさ)。表示エレメントは、特にピクトグラムの形態または英数字表示形式の、例えば警告ランプまたは情報ディスプレイである。
‐車両用照明の切換状態を、少なくとも1つのフォトダイオードにより測定された周辺光に応じて制御するために、車両用照明に接続されており、
‐合わせガラスの所定の領域に配置された、電気的に切換可能または制御可能な機能素子に接続されており、これにより、前記領域の透過特性を、少なくとも1つのフォトダイオードにより測定された周辺光に応じて制御することができるようになっており、前記領域は、好適にはガラス板の上側1/3に設けられた切換可能または制御可能な防眩部であり、かつ/または
‐車両内室に設けられた表示エレメントに接続されており、これにより、少なくとも1つのフォトダイオードにより測定された周辺光に応じて、表示エレメントの輝度(明るさ)を制御することができるようになっている。
