Beschreibung
Zusammenfassung:	PCT No. PCT/DE95/00082 Sec. 371 Date Aug. 1, 1996 Sec. 102(e) Date Aug. 1, 1996 PCT Filed Jan. 24, 1995 PCT Pub. No. WO95/21078 PCT Pub. Date Aug. 10, 1995Proposed is a device for operating a windshield wiper in the intermittent and continuous modes. To do this, at least one sensor (12) is provided, which emits signals in dependence on the coat of moisture or the amount of rain on a windshield to be cleaned, as well as an electronic control (16) for operating the windshield wiper (11) in dependence of the signal from sensor (12). The number for the sensor signals (E) per wiping interval (WP) is recorded as control signal (n) in one evaluating mechanism (14). Furthermore and depending on whether at least one threshold value (S1, S2) is exceeded or not reached by the control signal (n) or a signal (M1, M2), derived from control signals, there is a changeover between intermittent and continuous modes by means of a changeover device (21, 22).
