Patent number: 7586933Abstract: The invention concerns a network comprising an interconnecting network and several network nodes that are coupled to said interconnecting network and are designed to adapt their local communication time schedule to the communication time schedule of at least one other network mode, prior to being integrated as active network nodes. A network node to be integrated checks the activity of other network nodes and if no activity is identified, sends out positional messages for other network nodes, said message being fixed by predetermination in its communication time schedule. If a network node cannot be integrated as a reference node, it can only be integrated as an active node if it adapts its local communication time schedule to that of the reference node after receiving positional messages and if a check as to whether its own communication time schedule agrees with the communication time schedules of at least some of the active network nodes proves positive.Type: GrantFiled: April 4, 2003Date of Patent: September 8, 2009Assignees: Robert Bosch GmbH, Bayerische Motoren Werke AG, DaimlerChrysler AG, Freescale Semiconductor, Inc., GM Global Technology Operations, Inc., NXP B.V., DECOMSYS—Dependable Computer Systems, Hardware und Software Entwicklung GmbHInventors: Ing Ralf Belschner, Bernd Hedenetz, Christopher Temple, Anton Schedl, Josef Berwanger, Martin Peller, Thomas Führer, Arnold Millsap, Thomas Forest, Gregor Pokorny, Peter Fuhrmann
