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