Abstract
A windshield wiping device, in particular for cleaning a windshield of the motor vehicle, includes at least one wiper and a control device. The at least one wiper is driven by an electrical drive motor and displaceable between two end positions. The control device processes a current wiper position and switching signals of a manually operated switching element via input variables. The control device controls a supply voltage of the electrical drive motor and a wiper velocity via an output variable. The at least one wiper moves from end position to end position. In a first switch position of the switching element, the at least one wiper has a first velocity. In a second switch position of the switching element, the at least one wiper has a second velocity, which is greater than the first velocity. The at least one wiper in the second switch position moves at the first velocity each time it is in the vicinity of an upper and lower end position. An electrical drive motor has a contact disk system, rotating synchronously with revolutions of the electrical motor for the periodic switchover between the second velocity and the first velocity.
