A method for detecting liquid on a windowpane in which radiation is emitted by at least one radiation emitter, the radiation is coupled into the windowpane via at least one optical element, and, after reflection in the windowpane, the radiation is coupled out of the windowpane. The radiation which is coupled out of the windowpane is captured in single measurements. A measurement cycle is formed from a multiplicity of single measurements. An average value is calculated from the measurement results of a measurement cycle. The average value is used a reference value for the single measurements of the subsequent measurement cycle currently in progress. The differences between the measured values of the single measurements of a measurement cycle currently in progress and the reference value are determined. The differences between the measured values of the single measurements of the measurement cycle currently in progress and the reference value are evaluated statistically. A conclusion is drawn regarding the state of coverage with liquid of the measuring section on the windowpane from the statistical evaluation.
