A system and method for remote control of functionalities of a vehicle, for example a motor vehicle reserved for hire, is provided. The system and method include transmission and receipt of information between a mobile terminal, a remote vehicle management system and a control unit of a vehicle to remotely control, particularly to remotely initiate, particular functionalities of a vehicle which has been selected, particularly reserved, in advance using the vehicle management system. The mobile terminal is identified to the vehicle on the basis of an interchange of identifiers that the vehicle and the terminal have received in advance from the vehicle management system.

Remote control of vehicle functionalities by means of a mobile terminal

A central communication unit of a motor vehicle and to a method for controlling the communication between a plurality of applications by way of such a central communication unit are provided. The central communication unit has a communication organization module, which can actively distribute the available external radio connection capacities between the central communication unit and at least one transmitting/receiving device to individual active data connections of the applications in accordance with predetermined criteria. In the central communication unit, the available external radio connection capacities are distributed among the individual data connections of the individual applications in a specific, controlled manner. The criteria for this are the demand for connection capacity and/or the priorities of the different data connections.

A time-division multiplex method for serial data transmission includes executing a first priority resolution for messages to be transmitted by a plurality of stations on a communications channel and which are assigned to a first prefix, and transmitting a first data frame by a first station of the multiplicity of stations, wherein the first station transmits a first message with the first prefix and with the highest priority, during a predefined first access slot. The method also includes executing a second priority resolution for messages to be transmitted on the communications channel and which are assigned to a second prefix, and then transmitting of a second data frame by a second station of the plurality of stations, where the second station transmits a second message with the second prefix and with the highest priority of the second priority resolution, during a predefined second access slot.

Access method with access slots and priority resolution

A method for operating a station for serial data transmission using data frames in a communication network, configured to perform a carrier sense multiple access with collision avoidance (CSMA/CA) method, includes performing a first priority resolution for a specific first data frame to be transmitted on a communication channel, and establishing whether the specific first data frame to be transmitted has a highest priority. The method also includes performing a first backoff if the specific first data frame has the highest priority, transmitting the specific first data frame if the communication channel is free after the backoff, and raising the priority of the specific first data frame, in the absence of acknowledgement of the transmission of the specific data frame, to a priority level that is used exclusively for untransmitted data frames.

Station and method for serial data transmission using dynamic reprioritizing of data frames

A communication device for a vehicle has a first communication unit and a second communication unit. The first communication unit is configured to communicate with a server via a first communication protocol. The second communication unit is configured to communicate with at least one further vehicle via a second communication protocol. The first communication unit is configured to receive from the server control information for the second communication protocol and to forward it to the second communication unit. The second communication unit is configured to perform, depending on the forwarded control information, at least one predetermined setting for communicating with the at least one further vehicle by use of the second communication protocol.
