Abstract:
1. A windshield wiper system is provided with two wipers ( 1 , 2 ) that travel in opposite directions and are each drivable by a separate motor (M FS , M BS ), wherein a regulating unit ( 7 ) is provided for triggering the motors (M FS , M BS ) separately from each other by means of control signals, wherein the regulating unit ( 7 ) triggers the motors (M FS , M BS ) of the wipers ( 1 , 2 ) in order to preset a time-dependent angular position of the wipers according to a trigonometric function (φ(t)), wherein the trigonometric function is a sinusoidal function, wherein said sinusoidal function presets the angular position of the wipers to be wider than an angular position that is preset according to a pure sine function in a first reversal point of the wipers and wherein said sinusoidal function preset the angular position of the wipers to be narrower than the angular position that is present according to the pure sine function in a second reversal point of the wipers, wherein the trigonometric function for the wiper ( 1 , 2 ) of a passenger side corresponds to: and the trigonometric function for the winer of a driver's side corresponds to: where φ
