ABSTRACT:
In order to ensure, when the drive (1) is in a non-operating state, a self-locking that counters a change in position of the wiper (5), an electronically implemented self-locking is provided. To this end, the controller (S) of the wiper system monitors the wiper (5) during the non-operating state of the drive (1) by evaluating the position sensor signals for a change in position and, in response to the position monitoring, activates the drive (1) in order to return the wiper (5) into a set position (U, P).
