摘要

The motor vehicle windscreen wiper has a control for the wiper motor and the windscreen wash motor. The wiper (51) moves to and fro between end positions (A1,A2) over the windscreen surface (50a). Water (W) is sprayed from a wiper section at an intermediate position (A3). The control has a section to determine if the vehicle speed equals or exceeds a threshold level. A further control section registers if the wiper control is activated and if the wash spray can be used at the vehicle speed.
