OG exemplary drawing
 
1. A vehicle pane with a temperature sensor, comprising a substrate and a transparent electrically conductive coating on a surface of the substrate, wherein
a temperature measuring field that is electrically isolated from the surrounding transparent electrically conductive coating by a separating line is formed in the transparent electrically conductive coating,
a measurement current path running between two electrical contact points is formed from a region of the transparent electrically conductive coating in the temperature measuring field,
the two electrical contact points is are connectable to a voltage source such that an electric current flows through the measurement current path,
the two electrical contact points are connectable to an analysis unit that is adapted to measure a current strength of the electric current, determine an electrical resistance of the measurement current path therefrom, and determine a temperature from the electrical resistance using calibration data, and
the vehicle pane further comprises a peripheral masking print that surrounds a central through-vision region, wherein the two electrical contact points are arranged in a region of the masking print.
