The invention relates to a windscreen wiping device for a motor vehicle, comprising at least one wiper, a wiper drive (1), an electronic control device (2) that controls the wiper drive (1), a first signal transmitter for capturing the angular position of the wiper, and a first control line (7) that can emit an angle position signal captured by the first signal transmitter to the control device (2). According to the invention, a second signal transmitter for capturing the angular displacement of the wiper is provided. A second control line (8) that can emit an angle modification signal captured by the second signal transmitter to the control device (2) is provided. Said claimed windscreen wiper device has the advantage that it has a permanent self-locking device for at least one wiper.

1. A windscreen wiping device for a motor vehicle, the device comprising: at least one wiper,a wiper drive,an electronic controller which actuates the wiper drive,a first signal transmitter for recording an angular position of the at least one wiper,a first control line for feeding an angular position signal, which is recorded by the first signal transmitter, to the controller,a second signal transmitter is provided for recording a change in angle of the at least one wiper,a second control line for feeding a change-in-angle signal, which is recorded by the second signal transmitter, to the controller, anda transmitter magnet, said transmitter magnet being arranged on an output side of the wiper drive, and the second signal transmitter being a magnetic field-dependent switching element. 2. The windscreen wiping device as claimed in claim 1, wherein the magnetic field-dependent switching element comprises a reed contact switch. 3. The windscreen wiping device as claimed in claim 2, wherein the first signal transmitter is a magnetic field-dependent position sensor. 4. The windscreen wiping device as claimed in claim 3, wherein the controller is connected to an vehicle battery when an ignition is switched off. 5. The windscreen wiping device as claimed in claim 1, wherein the first signal transmitter comprises a magnetic field-dependent position sensor. 6. The windscreen wiping device as claimed in claim 1, wherein the controller is connected to a vehicle battery when an ignition is switched off. 7. A method for operating a windscreen wiping device, which has at least one wiper, for a motor vehicle, the method comprising: recording an angular position of the wiper;recording a change in angle of the wiper; andproviding the angular position of the wiper and the change in angle of the wiper to an electronic controller, wherein the electronic controller implements self-locking in an inoperative state of the wiper, wherein, in the event of self-locking, a deviation in the angular position of the wiper from a setpoint position of the wiper is compensated for by actuating the wiper drive,wherein the controller can be changed over to a standby state, wherein the power supply to the electrical components of the windscreen wiping device is reduced or switched off in the standby state, the change in angle of the wiper is recorded in the standby state, and self-locking of the wiper is activated when the measured change in angle exceeds a predetermined threshold value. 8. The method as claimed in claim 7, wherein the controller is changed over to the standby state when an ignition of the motor vehicle is switched off.
