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.
