Abstract
Operation of a windshield wiper system for cleaning a windshield of a motor vehicle includes driving at least one wiper by an electric drive motor so that the at least one wiper shifted between two terminal positions, processing by a control unit as the input variable the output signals of a rain quantity and the switching signals of a manually controllable switch mechanism, and processing as the output variable a supply voltage of the electric drive motor so as to control the wiper speed, operating the at least one wiper ( ) with variable intermittent interval times and at variable wiper speeds, as a function of a rain quantity detected by the rain sensor ( ), so that the precisely one wiper speed and precisely one intermittent interval time are associated with each measured rain quantity, and moving the at least one wiper ( ) in an intermittent mode with a lower speed than in a continuous mode.
