Device for operating a windshield wiper

摘要

A device for operating a windshield wiper with an automatic wiper control. A fast reaction to a suddenly occurring heavy wetting event is assured without adversely affecting the sequence of intermittent wiper operation. This is achieved by an evaluation unit which has a surge detection stage that makes it possible to detect, during intermittent operation when a sensor signal falls short of a surge threshold and by triggering a control signal for at least one wiping action when the signal falls short of the surge threshold.
