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 device for simulating a data transmission via a data transmission network, especially in a motor vehicle, for evaluating the transmission quality via the network as a function of an interference environment and of a channel characteristic of the network.

Abstract: A method is described for establishing one user from multiple users of a data network as a pilot master for emitting a pilot signal, to which the other users of the data network may synchronize themselves. In the related art, a pilot signal is typically generated by a separate pilot signal generator or a permanently predefined selected user. However, this has the disadvantage that if the pilot signal generator or the selected user malfunctions, synchronization and therefore also communication of the users with one another via the data network is no longer possible. In order to avoid this disadvantage, it is suggested that at least two of the users of the data network be implemented to be pilot-master-capable and one of them assume the pilot mastership according to a described method.

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 method and a supply line structure for transmitting information between electrical components in a motor vehicle is described. The information is transmitted over a data bus. At least some of the components are powered via a supply line structure. To make the transmission of information between the components fail-safe, the information is also transmitted over the supply line structure in addition to over the data bus at least after a failure of the data bus.

Abstract: A method and a computer program for modeling an interfering pulse in a vehicle electric system are described. Previous approaches for synthesizing such interfering pulses have proven to be insufficiently realistic for the simulation of certain application cases. An interfering pulse is therefore modeled by random determination of the parameters of the parameter set representing the interfering pulse to be modeled on the basis of the density functions belonging to the parameters and by substituting the parameters thus obtained into a predetermined mathematical function. The interfering pulse modeled in this way is also a suitable starting point for modeling a pulse pattern, i.e., a random sequence of individually spaced interfering pulses and a pulse interferer scenario, i.e., a random sequence of individually spaced pulse patterns.

Abstract: A device for wireless transmission of a trigger signal, in particular for a restraint system, which has a redundancy path to ensure reliable triggering of a restraint system, is proposed. On a primary side of a transmitter a redundancy unit is arranged; this generates a redundancy signal from a trigger command, the redundancy signal being detected by an enable unit on the secondary side in order to enable a trigger circuit for the restraint system, the trigger circuit then being triggered by an evaluation unit on the secondary side via a trigger signal. The trigger circuit triggers a restraint system.
