Abstract
The invention relates to a windshield wiper system with two wipers (1, 2) that travel in opposite directions and can each be driven by a separate motor (MFS, MBS), wherein a regulating unit (7) is provided for triggering the motors (MFS, MBS) separately from each other by means of control signals, wherein the regulating unit (7) triggers the motors (MFS, MBS) of the wipers (1, 2) in order to preset a time-dependent angular position of the wipers according to a trigonometric function φ(t).
