Abstract
A device (,) for operating a windshield wiper (,) is proposed, with a moisture sensor (,) for detecting the wetness of a window that in addition to detecting rain and droplets also detects fog and drizzle. The measured values (Us) of the moisture sensor (,) are allocated incremental values (Ink) by the control unit (,). The difference between two successive incremental values (Ink) is to be added, with a sign (+ or −), in the memory (,) to a sum (&Sgr;) of differences formed previously in the same way, and when a threshold (S) is reached by the sum (&Sgr;) stored in the memory (,), the control unit (,) trips a wiper operating mode.
