Abstract: A method for synchronizing two communication networks of an electronic data-processing system, each of the networks including one or more respective nodes, may include establishing for each of the networks a respective time schedule that establishes at least one respective time slot for a respective synchronization message. The synchronization message time slots are established to coincide. The synchronization message of the first communication network is generated by one of the nodes of the first communication network. The synchronization message of the second communication network is generated as a function of the synchronization message of the first communication network.

Abstract: A method is for transferring data between a data transmission system and a processor of a participant in the data transmission system. All components of the data transmission system are synchronized to a common global time base. The operating-system time base of the participant processor is synchronized to the global time base of the data transmission system. To render possible a synchronization of the operating-system time base to the global time base in complex data transmission systems as well, it is provided that the operating-system time base of the participant processor be synchronized to the global time base of the data transmission system at least prior to a data transfer, and, to this end, that a synchronization clock pulse that is synchronous to the global time base of the data transmission system be provided for synchronizing the operating-system time base. This synchronization clock pulse is provided by a suitable arrangement that is implemented as hardware and/or software.

Abstract: A supply line structure for the energy supply of electrical components of a motor vehicle, and for transmitting information between at least a portion of the components. To reduce the interference susceptibility of the supply line structure in a Powerline Communications, and at the same time to continue to be able to ensure the energy supply of the electrical components via the supply line structure, it is provided that the supply line structure have separate supply lines, electrically isolated from the vehicle body, as return lines from the components to at least one energy source of the motor vehicle. The supply lines of the supply line structure preferably take the form of coaxial lines or twisted pair lines.

Abstract: A supply line structure for supplying energy to electrical components of a motor vehicle, and for the transmission of information between at least a portion of the components (so-called Powerline Communications). To improve the channel characteristics of the information transmission via the supply line structure, it is proposed that the supply lines be arranged in a star configuration having at least one star point, the or each star point an impedance which corresponds to the characteristic impedance of the individual supply line branches running into it. To that end, it is proposed in particular that at the or each star point, an additional series resistor, frequency-dependent for frequencies below 100 MHz, be disposed in the incoming supply line branches. The series resistor is preferably configured as a ferrite sleeve.

Abstract: A communications system for a motor vehicle, including a plurality of electrical components, a data bus structure to which the components are connected in order to transmit information among the components, and a power line structure to which the components are connected in order to be supplied with power. The information is transmitted in successive cycles over the data bus structure, each cycle including at least one time window for transmitting information at specific points in time and at least one event window for transmitting information in response to specific events. The communications system includes an arrangement for redundantly transmitting information which merely transmits the information transmitted in the at least one time window over the data bus structure at least partially over the power line structure as well.

Abstract: A method and an arrangement are disclosed for modeling a mechatronic system in a motor vehicle in the context of an object-based ordering concept as a mapping in the unified modeling language. The elements of the CARTRONIC® with components and envelopes as their classes or objects and orders (with feedback), inquiries (with hint) and requests as their communication relationship are presented based on examples together with the essential rules from the overall control rules. A mapping requirement in the UML elements is shown for these modeling elements.

Abstract: A system for the wireless transmission of information and energy between a removable vehicle seat and the vehicle body, in which the vehicle seat is detected by measuring the inductance. In this connection, the period of an oscillating circuit is determined, in which the winding of the primary side, and thus the inductance, is connected. In this context, the frequency of the resonance voltage is determined as a function of time. In this context, the zero crossings of the resonance voltage is measured. Alternatively, the secondary side impedance is additionally measured on the primary side by a forced oscillation, namely by a voltage decay in a resonance circuit in which the winding is connected as inductance. A monitoring of the performance reliability of a firing pellet is thereby implemented.

Abstract: The invention concerns an inductive transmitter comprising two coils (1, 2), each with one core (3, 4). The two cores (3, 4) are capable of being moved relative to each other. Two systems are integrated in the transmitter that make it possible to simultaneously transmit data and/or energy, as well as the position of the two cores (3, 4) relative to each other. Finally, the transmission of data and/or energy takes place by means of induction, and the determination of the position of the two cores (3, 4) relative to each other takes place via a measurement of the magnetic field that exists between the two coils (1, 2).

Abstract: An operating element having a first control element that is rotatable about a first axis, and having at least one second control element that is rotatable about a second axis and that does not coincide with the first axis. The operating element may include apparatuses, arrangements or structures to influence the torque required to rotate at least one of the control elements. An operating device having an operating element has a controller to influence the torque required to rotate at least one of the control elements as a function of the context. The operating element and the operating device permit a good haptic feedback and/or user guidance in adjusting a parameter or in scrolling through a menu, so that visual contact with the operating element or a pointer moved with the operating element in a menu is not necessary.
