Abstract: A method for determining a need for a message content for a transmitting station. The method includes: determining an anticipated need for a message content according to one or more receiver stations, wherein the anticipated need with respect to the message content is based on the need of the transmitting station; computing at least one metadata configuration for the message content based on the determining of the anticipated need for the message content; augmenting the message content based on the computed at least one metadata configuration, wherein the metadata configuration specifies in which way the message content is to be adapted dependent on the one or more receiver stations and/or according to a message type to be transmitted.

Abstract: A method for distributing communication resources between subfunctions of a function, executable on two or more executability levels, of a communication system for a vehicle. The method includes ascertaining a communication resource requirement of the function on a first executability level, provided by subfunctions of the function; checking whether the communication resource requirement is able to be met with available communication resources; if not, determining at least one of the subfunctions that is able, with the available communication resources, to provide only a second executability level that is restricted in relation to the first executability level; distributing available communication resources between the two or more subfunctions comprising restricting the available communication resources for one or more other subfunctions that differ from the at least one subfunction, so that the two or more subfunctions provide the second executability level of the function following the restriction.

Abstract: A control apparatus for controlling data traffic, which is generated by functional units of a vehicle, via a radio device includes a functional interface for connecting the control apparatus to functional units and for reading in requirement signals representing requirements of the functional units in terms of a capacity required in the future for the data traffic for transmitting functional data. The control apparatus also comprises a transmission interface for connecting the control apparatus to the radio device and a determination device which is designed to use a route signal, a network signal, and the requirement signals, in order to determine capacity signals representing partial capacities available in the future for the functional units.

Abstract: A method for determining a position of a vehicle. The method has a step of carrying out self-locating of the vehicle using a locating device of the vehicle in order to generate a provisional position of the vehicle. The method also has a step of reading in a position signal, the position signal representing a position of another vehicle. Moreover, the method has a step of ascertaining a relative position of the vehicle relative to the other vehicle with the aid of the position signal in order to determine the position of the vehicle using the self-locating and the relative position.

Abstract: The invention relates to a method for a communication between a fueling device (2) and a vehicle (4), having the steps of coupling the fueling device to a tank (6) of the vehicle by means of a fuel hose (10), providing pressurized fuel to the fuel hose, varying the pressure on the fuel hose by superimposing a specified base pressure with a pressure sequence in order to modulate a first signal to be transmitted, detecting the pressure being applied to the fuel hose by means of the vehicle, and extracting the first signal to be transmitted from the detected pressure.

Abstract: A method for outputting a signal as a function of a transmission path to be selected, to transmit a data packet from a transmitter unit to a receiver unit connectable to the transmitter unit via at least two transmission paths. The method includes: ascertaining, in each instance, a prediction value of at least one transmission path parameter for each of the at least two transmission paths, using a short-term determination unit, to provide a transmission path information item including the predicted values, to a planning unit; selecting the transmission path to be used for transmitting the data packet, from the at least two transmission paths, using the planning unit, based on the ascertained transmission path information item; and outputting the signal using the planning unit to transmit the data packet from the transmitter unit to the receiver unit on the selected transmission path.

Abstract: A method for identifying an object as the source of a V2X signal. The method includes: receiving a V2X signal from a source by a receiver of a first vehicle; performing a relative position estimation using an environment sensor system of the first vehicle, an object from the surroundings of the first vehicle being detected, and a relative position between the first vehicle and the object being determined, the environment sensor system receiving environment signals of the object, and the object modulating the environment signals at least with a part of a V2X signal of the object; receiving the modulated environment signals by the environment sensor system of the first vehicle, and demodulating the received environment signals by the first vehicle, and ascertaining a V2X identifier of the object; comparing the V2X identifier of the object with the V2X signal of the source.

Abstract: A method is described for creating observation data, in particular by at least one vehicle, traveled road segments being ascertained by the vehicle, lanes of the road segments traveled by the vehicle being ascertained by the vehicle, and the ascertained road segments together with the ascertained traveled lanes being transmitted as observation data from the vehicle to an external server unit. A method for ascertaining a number of traffic lanes, to a system, to an external server unit, and to a control unit are also described.

Abstract: A method for determining an environment-specific data profile for a satellite-based determination of a position of a vehicle includes ascertaining the position of the vehicle and receiving satellite data. The environment-specific data profile is determined using the ascertained position of the vehicle, a satellite position of a satellite from the received satellite data, and a path length of a satellite signal between the satellite position and the vehicle position determined from the satellite data.
