Summary:A windscreen wiper device (I) for a motor vehicle. The device includes at least one wiper motor (2) on which a motor crank (4) is provided connected to at least one gearing (3) which is downstream of said wiper motor (2), so as to drive a wiper arm that is coupled thereto such that said arm performs an oscillating wiper movement on a windscreen of said motor vehicle, said wiper motor (2) being coupled to a control unit. Motor power generated by the wiper motor (2) is adjusted by the control unit depending on a transmission ratio which results from the position of said gearing (3). The control unit delays a reduction in the motor power until after the motor crank (4) has accelerated out of the respective wiper arm turning points to produce as uniform a wiper arm movement as possible on the windscreen.
