A windscreen wiping system for motor vehicles comprises a wiper lever (30, 32, 102, 104, 202, 204), which has a wiper element (36, 40, 110, 112, 210, 213) in contact with the windscreen (42, 100, 200), and which is driven back and forth between two reversal positions by a driving unit comprising an electric driving motor (10, 130, 132, 230, 232). To obtain a particularly reliable, silent and precisely operating wiping system, at least one sensor (44, 50, 150, 152, 154, 156, 164, 166, 262, 263, 266, 267, 260, 264, 265), which detects a given operating position of the wiper lever (30, 32, 102, 104, 202, 204) and co-operates with a control device (48, 140, 238) that governs the electric driving motor (10, 130, 132, 230, 232), is arranged on the motor vehicle. |
