Abstract: A method for supplying data which can be received by a vehicle in a vehicular ad-hoc network, in which the data is transmitted between subscribers to the vehicular ad-hoc network using a location-based communications protocol, involves: identifying a geographical location area of the vehicle; selecting a suitable communications protocol (for the identified location area; and receiving the data using the selected communications protocol in such a way that the received data is available to at least one network layer of the communications protocol.

Abstract: In a communication system for vehicle-to-environment communication, data to be transmitted is transmitted wirelessly as data packets. The system includes a communication unit and an application unit which are in contact with one another via an internal communication link, the communication unit having a high-frequency antenna and a transceiver for physical data transmission, in addition to a data processor for controlling the physical transmission. The application unit has at least one data processor configured to execute application programs, to control the access of the application programs to the vehicle-to-environment communication and to execute data communication security applications. The data processor of the application unit is configured to forward the data packets including the routing between communication users and to segment the data stream.

Abstract: The disclosure relates to a method for generating a time stamp in a vehicle which participates in a vehicle ad-hoc network. The method includes associating, by giving out the time stamp, an event, which is transmitted in a message, with a clock time. The clock time is generated by updating a global time base that may be derived from a global satellite navigation signal (GNSS). The method includes checking whether a GNSS signal may be received. The method also includes generating the clock time based on a local time base if an insufficient number of global satellite navigation signals for deriving the global time base is available.

Abstract: An electronic control device comprising a number of application partitions and a firewall partition, also comprising a number of secure interfaces which can only be accessed by the firewall partition. This increases the safety of the electronic device for example when used as an embedded controller.

Abstract: The invention relates to a pump module (2) comprising a housing part (4) with precisely determined force introduction points (25) in relation to adjacent components. Supporting elements (24, 27) and a groove (26) are located between the force introduction points (25) and a disc element (20) that comprises a partially annular channel (10). Forces that are introduced into the housing parts (4) thus lead to negligible deformations in the areas of said housing parts (4) that are adjacent to the impeller.

Abstract: The invention relates to a method and to an arrangement for monitoring signals which are guided to a multi-phase motor by an end stage and the pulse width thereof is controlled by a controller. The total of the pulse widths of the signals of each phase is measured by, respectively, a counter, respectively for a predetermined program flow in the controller. The meter reading is read by a counter according to a predetermined period of time and an error signal is produced if the total amount of time exceeds a predetermined tolerance range.
