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.

Abstract: A pneumatic system for operating a drive for a windshield wiper for a rail vehicle, wherein the windshield wiper drive has a piston guide device that has a first connection and a second connection opposite the first connection. At least one piston in the piston guide device carries out linear movements in opposite directions along the main direction of extension of the piston guide device to bring about an alternating rotational movement of the wiper shaft. The pneumatic system has a supply connection for a compressed air supply, wherein the supply connection is connected to the first connection via a first normal operation connection line and a first emergency operation connection line arranged parallel thereto and to the second connection via a second normal operation connection line and a second emergency operation connection line arranged parallel thereto.
