| 摘要 |
The invention relates to a windscreen wiper device (1) for a motor vehicle, said device comprising at least one wiper motor (2), particularly a reversing motor, 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) can be adjusted by the control unit depending on a transmission ratio which results from the position of said gearing (3). In order to carry out dynamic reverse processes of the wiper arm out of its turning point to produce as uniform a wiper arm movement as possible on the windscreen, 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. |
