Abstract: A system for transmitting and receiving data, in particular for a rail vehicle, includes at least one in-vehicle control unit for processing and generating data, at least one external server unit with a communication device for establishing a communication connection with at least one in-vehicle interface, and at least one in-vehicle interface for transmitting data generated by the at least one in-vehicle control unit and for receiving data transmitted by the at least one external server unit. The at least one in-vehicle control unit and the at least one in-vehicle interface are interconnected so as to transmit data through an electronic filter device.

Abstract: A method for logging an item of information relating to a rail vehicle, includes recording a speech input having the item of information, by a user of the rail vehicle and saving the recorded speech input as an audio file. The saved audio file is sent via a wireless communications network to a subscriber, remote from the rail vehicle, of the communications network. A device logs the subscriber, remote from a rail vehicle, of the communications network.

Abstract: A method for operating a rail vehicle includes transmitting an identifier for a software component and/or an identifier for a hardware component of a control system of a rail vehicle. The identifier is transmitted from a computation unit of the rail vehicle to a stationary central computation unit, at least at one predetermined point in time.

Abstract: A method for monitoring the on-board battery of a rail vehicle. The state of charge of the on-board battery is regularly ascertained in an automated manner and is compared with a desired state of charge value. In case the ascertained state of charge value drops below the desired state of charge value, a message is generated for initiating measures for charging the on-board battery.

Abstract: A method for controlling a rail vehicle includes recording a voice message of an user of the rail vehicle which contains a control parameter for controlling the rail vehicle. The control parameter is extracted from the recorded voice message. The extracted control parameter is displayed and the rail vehicle is controlled on the basis of the extracted control parameter only upon detection of a release command of the user that the extracted control parameter may be used for controlling the rail vehicle.

Abstract: A warning device and system for a rail vehicle includes at least the following components: an error detection apparatus, designed to detect at least one error condition of the rail vehicle, an image memory containing a number of images which indicate an actual condition of a rail vehicle, a first selection unit for selecting at least one of the images from the image memory in accordance with a detected error condition of the rail vehicle, at least one user interface with at least one display unit, a display control unit for controlling the display unit such that the image selected in accordance with the detected error condition is output on the display unit. There is also disclosed a corresponding method for warning a vehicle driver of a rail vehicle and the use of a warning system of a rail vehicle for displaying an actual condition of a rail vehicle.

Abstract: A method and an apparatus transmit data between a first communications network of a first track-guided vehicle unit and a second communications network of a second track-guided vehicle unit. In order to ensure flexible data transmission between the first and second communications networks, the data between the first and second vehicle units are transmitted via a terrestrial data device.
