Described is a wiper system for motor vehicle windows, more particularly motor vehicle windscreens, comprising at least one wiper (), at least one motor () that drives the at least one wiper (), and a switching device () for directly controlling the motor (), wherein the switching device () has one or two switching elements () by means of which at least four switching states can be selected, and wherein selecting one of the switching states causes an operating mode of the at least one wiper () to change.

Wiper system for motor vehicle windows, more particularly motor vehicle windscreens

The invention relates to a drive control means, in particular for controlling a windscreen wiper drive of a motor vehicle, having a first interface and a second interface, wherein, after receiving control information via the first interface, the drive control means is arranged to configure itself in a master role and to output control information via the second interface in order to control a further drive control means.

Windscreen wiper drive control system and method

The invention relates to a windscreen wiping device for a motor vehicle, comprising at least one wiper, a wiper drive (), an electronic control device () that controls the wiper drive (), a first signal transmitter for capturing the angular position of the wiper, and a first control line () that can emit an angle position signal captured by the first signal transmitter to the control device (). According to the invention, a second signal transmitter for capturing the angular displacement of the wiper is provided. A second control line () that can emit an angle modification signal captured by the second signal transmitter to the control device () is provided. Said claimed windscreen wiper device has the advantage that it has a permanent self-locking device for at least one wiper.

Electronic self-locking device for a windscreen wiping device

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