The invention relates to a rainwater detection device for detecting raindrops on a surface (14), comprising at least one sensor unit (16), which comprises at least one capacitive sensor element (22), said sensor element being designed and/or arranged in such a way that the sensor element (22) is electrically connected to the sensor unit (16). Such that a capacitance characteristic variable of the sensor element (22) is changed as a function of the contact of the surface (14) by means of an object; and at least one evaluation unit (26), which is designed to detect raindrops on the surface (14) on the basis of the differential signal of the sensor element (22). According to the invention, the evaluation unit (26) is designed to detect raindrops on the surface (14) on the basis of the differential signal, in particular a symmetric variable with respect to zero.

    本发明涉及一种雨水识别装置,用于检测表面(14)上的雨滴,具有:至少一个传感器单元(16),其包括至少一个电容式传感器元件(22),其中,所述传感器元件这样地构造和/或布置,使得所述传感器元件(22)的电容特征参量根据所述表面(14)的借助于对象的接触而改变;和至少一个分析处理单元(26),所述分析处理单元被设定用于根据所述传感器元件(22)的差分信号识别所述表面(14)上的雨滴。本发明建议,所述分析处理单元(26)被设定用于根据所述差分信号特别是相对于零点的对称特征参量识别所述表面(14)上的雨滴。
