Abstract
In a method for detecting rain on a windshield, whose degree of wetting is determined with at least one sensor value, it is provided that the sensor value is determined piezoelectrically, wherein vibrations on the windshield are detected, which change depending on the degree of wetting or raindrops hitting the windshield. As a result, the entire windshield serves as a detection surface, thereby yielding a high accuracy.
