1. A method for adapting a signal processing of at least one sensor device that is arranged behind a windowpane in a motor vehicle, wherein the adaptation of the signal processing comprises:
- providing a temperature signal from at least one temperature sensor integrated in the sensor device,determining that a probability of ice on the windowpane is detected on the basis of the temperature signal, andchanging at least one detection threshold of a vehicle obstacle detection system if the probability of ice on the window pane is detected.

Abstract
The invention relates to a method for adapting the signal processing of at least one sensor device arranged behind a window in a motor vehicle, wherein the adaptation of the signal processing comprises changing at least one detection threshold value if a probability of ice being on the window is detected on the basis of a determined temperature, characterized in that a temperature signal of at least one temperature sensor integrated in the sensor device is used to detect the probability of ice on the window.
