Abstract (en)
[origin: WO2021160388A1] The invention relates to a vehicle pane with a temperature sensor, comprising a substrate (1) and a transparent electrically conductive coating (4) on a surface of the substrate (1), wherein - a temperature measuring field (10) is formed in the electrically conductive coating (4), said temperature measuring field being electrically insulated from the surrounding electrically conductive coating (4) by a separating line (11), - a measurement current path (14) running between two electric contact points (12 1, 12.2) is formed from a region of the electrically conductive coating (4) in the temperature measuring field (10), - the electric contact points (12.1, 12.2) can be connected to a voltage source such that an electric current flows through the measurement current path (14), and - the electric contact points (12.1, 12.2) can be connected to an analysis unit which is suitable for measuring the current strength of the electric current, determining the electric resistance of the measurement current path (14) therefrom, and determining the temperature from the electric resistance using calibration data.
