Abstract:
1. A windscreen wiper device ( 1 ) for a motor vehicle with at least one wiper motor ( 2 ) having a motor crank ( 4 ) connected with at least one gearing ( 3 ) downstream of the wiper motor in order to drive a wiper arm coupled therewith such that said arm executes an oscillating wiping movement on a windscreen of the motor vehicle, wherein the wiper motor is coupled with a control unit which adjusts a motor power generated by the wiper motor ( 2 ) as a function of a translation ratio resulting from the position of the gearing ( 3 ), characterized in that to generate as uniform a wiper arm movement as possible on the windscreen during a dynamic reversing process of the wiper arm out of a turning point, the control unit maintains a level of motor power until after the motor crank ( 4 ) has accelerated out of the respective wiper arm turning point.
