Abstract: In a method for carrying out a communication in a control unit, a message having an identification number is transmitted between a microcontroller and at least one system component, this identification number being used in the at least one system component as basis for a decision with the aid of a message filter as to whether this message is forwarded to a first module for linking a physical layer or to a second module for functions of the system component.

Abstract: In a subscriber of a communication system for transmitting data of a data stream in time slots of recurring communication cycles, the communication system includes a communication medium, the subscriber, and at least one additional subscriber. The subscribers are connected to the communication medium for data transmission purposes. To allow better utilization of the available frequency range for data transmission, the subscribers have device(s) for spectral spreading of the data of the data stream before transmission via a certain code sequence and have device(s) for transmitting the spread data in the time slots of the recurring communication cycles. The communication system is preferably designed as a FlexRay communication system, the spread data being transmittable in chronological synchronization in a time slot of the communication cycle by various subscribers of the system.

Abstract: A method is described for transmitting data between participants of a serial, ring-shaped communications arrangement in which the participants are serially connected to one another, wherein a data packet is passed from a participant provided as a master to further participants provided as slaves, wherein the data packet is passed from slave to slave, and wherein address information of the data packet is altered by each slave.

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.
