Patent number: 8493990Abstract: A cyclical time-based communication system, for the transmission of data (DATA) between users, comprising a databus and users connected thereto. The data transmission occurs within cyclical repeating timeframes, each with at least two timeslots. Each timeslot is provided for the transmission of a message (Ni). A message (Ni) comprises at least part of the data (DATA) and each message (Ni) is provided with a code (ID). The bandwidth available for data transmission may be better utilized, if the code (ID) is placed within the message (Ni), each message (Ni) is additionally provided with time information concerning the timeslot which may be extracted from the code, and at least one of the timeslots may be used for transmission of various messages in various cycles. In a preferred embodiment the information relating to the current cycle comprises an ordinal number. In the simplest case the number has two values 0 and 1.Type: GrantFiled: November 24, 2010Date of Patent: July 23, 2013Assignee: Robert Bosch GmbHInventors: Josef Berwanger, Anton Schedl, Ralf Belschner, Peter Lohrman, Matthias Kuehlewein, Thomas Fuehrer, Bernd Mueller, Florian Hartwich, Robert Hugel, Carsten Gebauer

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

Patent number: 6934775Abstract: The invention relates to an operating method for a data bus for several parties with flexible, timed access. According to the method, the parties are synchronized, the bus messages are sent from the parties in a hierarchical sequence and are sent at least in part, only if necessary. A logic element is provided between the parties and the data bus which only gives bus access to each party when said party is allowed to send and for the duration of the send operation.Type: GrantFiled: April 3, 2002Date of Patent: August 23, 2005Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Martin Peller, Josef Berwanger

Publication number: 20050141565Abstract: The invention refers to one of a number of nodes of a communication system. The nodes are connected to a communication media for transmitting data among the nodes. Said one node comprises a communication controller, across which the node is connected to the communication media, and a bus guardian for controlling access of the communication controller to the communication media. In order to provide a cheap but nevertheless reliable way for monitoring the synchronized clock signal of a node of a communication system and in particular for detecting deviations of the synchronized clock signal it is suggested that a synchronized clock signal from the communication controller is made available to the bus guardian, and that the bus guardian comprises means for monitoring the synchronized clock signal using a bus guardian internal clock signal, which is generated by means of an electronic circuit and which is less accurate than the synchronized clock signal to be monitored.Type: ApplicationFiled: July 7, 2003Publication date: June 30, 2005Applicants: Robert Bosch GmbH, Daimler Chrysler AG, Bayerische Motoren Werke AG, General Motors Corp., Motorola Inc., Koninklijke Philips Electronics N.V.Inventors: Thomas Forest, Bernd Hedenetz, Mathias Rausch, Christopher Temple, Harald Eisele, Bernd Elend, Jorn Ungermann, Matthias Kuhlewein, Ralf Belschner, Peter Lohrmann, Florian Bogenberger, Thomas Wuerz, Arnold Millsap, Patrick Heuts, Robert Hugel, Thomas Fuhrer, Bernd Muller, Florian Hartwich, Manfred Zinke, Josef Berwanger, Christian Ebner, Harald Weiler, Peter Fuhrmann, Anton Schedl, Martin Peller

Patent number: 6806590Abstract: A data bus arrangement for a plurality of nodes connected to each other including a logical decision gate having a plurality of inputs corresponding to the number of nodes. A converter module is connected between each node and the logical decision gate. Each convertor module converts an optical output from one of the nodes to an electrical signal which is fed to one of the inputs of the logical decision gate. A separate switch is connected between an output of the logical decision gate and an input of each one of said convertor modules for controlling the convertor module independent of an output signal on the output of the decision gate.Type: GrantFiled: November 21, 2000Date of Patent: October 19, 2004Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Karel Smuk, Robert Griessbach, Martin Peller, Josef Berwanger

Patent number: 6744985Abstract: A data bus structure for cooperating with a plurality of nodes which are connected to each other. The data bus structure includes optical transmission modules associated with each node and a logical decision gate having inputs associated with each node. The logical decision output signal is provided in parallel to each node through the optical transmission modules. These modules serve to convert optical signals from the nodes to electrical signals and output to the logical decision gate and to convert electrical signals output from the logical decision gate to optical signals and output to the nodes. In order to separate a single node from the data bus, the transmission mode is monitored and an independently controlled switch is positioned between the logical decision gate and the optical transmission module. This arrangement functions to exclude a node from bus communication while leaving the remaining nodes uninterrupted.Type: GrantFiled: November 16, 2000Date of Patent: June 1, 2004Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Karel Smuk, Robert Griessbach, Martin Peller, Josef Berwanger

Publication number: 20040081193Abstract: Method for transmitting data within a communication system, the communication system comprising a communication media and a number of nodes connected to the communication media, the data being transmitted across the communication media within a communication cycle comprising a number of time slots assigned to one or more nodes of the communication system. In order to provide a possibility for a data transmission within communication cycles, which can satisfy the demands in communication systems for safety critical applications, too, it is suggested, that the communication cycle is initiated by an external event. The external event can be caused by manually setting a bit by a host, by a configurable timer in a controller host interface (CHI) or by an external trigger.Type: ApplicationFiled: July 7, 2003Publication date: April 29, 2004Inventors: Thomas Forest, Bernd Hedenetz, Mathias Rausch, Christopher Temple, Harald Eisele, Bernd Elend, Jorn Ungermann, Matthias Kuhlewein, Ralf Belschner, Peter Lohrmann, Florian Bogenberger, Thomas Wuerz, Arnold Millsap, Patrick Heuts, Robert Hugel, Thomas Fuhrer, Bernd Muller, Florian Hartwich, Manfred Zinke, Josef Berwanger, Christian Ebner, Harald Weiler, Peter Fuhrmann, Anton Schedl, Martin Peller
