  • Patent number: 10654449
    Abstract: A windscreen wiper control system controls a drive mechanism for at least one windscreen wiper arm to effect a reciprocating movement of the at least one windscreen wiper arm within a wiping range between a first position and a second position. The control system includes a detector that detects, upon activation of the control system, an uncertain position of the windscreen wiper arm within the wiping range but different from the first position. Upon detection of such an uncertain position, the control system returns the windscreen wiper arm to the first position at a predetermined reduced speed, the reduced speed being applied at least in a sub-range of the wiping range in the vicinity of the first position.
