First Claim
1. A control unit for a windscreen wiper system for a rail vehicle, the control unit comprising:
- an operating function interface designed for receiving an item of information about an operating mode of the windscreen wiper system;
a sensor interface designed for receiving at least one analog and/or digital sensor signal;
a control device designed for providing at least one control signal for the windscreen wiper system by using the information about the operating mode and the sensor signal;
a control output designed for outputting the at least one control signal; and
a supply voltage connection designed for providing an applied voltage to the interface and the device of the control unit,wherein the sensor interface comprises at least one switchable supply connection coupled to an angle of rotation sensor and a rain sensor,wherein the at least one switchable supply connection alternately switches the supply voltage connection between each of the angle rotation sensor and the rain sensor, andwherein the operating function interface and the sensor interface is an LIN bus interface.

Abstract
The invention relates to a control unit for a windscreen wiper system for a rail vehicle, comprising an operating function interface, a sensor interface, a control device, a control output, and a supply voltage terminal. The operating function interface is configured to receive an information via an operating mode of the windshield wiper system. The sensor interface is configured to receive at least one analog and/or digital sensor signal. Utilizing the information, the control device is configured to provide at least one control signal for the windshield wiper system via the operating mode and/or the sensor signal. The control output is configured to emit the at least one control signal. The supply voltage terminal is configured to provide an applied voltage, interfaces, and devices of the control unit, in particular to the control device.

6. A method for operating a windscreen wiper system for a rail vehicle, the method comprising:
-
reading-in an operating mode signal, the operating mode signal representing an item of information about an operating mode of the windscreen wiper system to be controlled; creating a control signal using the operating mode signal; outputting the control signal to the windscreen wiper system as an analog and/or digital signal; and driving the windscreen wiper system via the control signal, wherein the operating mode includes a parking, interval with multiple stages, wiping with multiple stages, rain sensor operation, and continuous operation, wherein, in the reading-in, a sensor signal is also read in, and wherein the creating the control signal is created by using the sensor signal, wherein the sensor signal is read in based on the output at least one switchable supply connection which alternately switches the supply voltage connection between each of the angle rotation sensor and the rain sensor.
