A method and computer program for modeling a noise pulse on a motor vehicle - on-board electrical system

摘要

A method for modeling of a field effect transistor pulse on a motor vehicle - the on-board network, the for the power supply of different motor vehicle - components and / or for the transfer of data between the components is used;at least a part of the components during operation of an n-p-n transistor pulses generated in the electrical system, comprising the steps of:– An empirical determining a plurality of field effect transistor pulses;– Simulation of the individual previously determined interference pulses by means of a suitable mathematical function with a respectively suitable parameter set, wherein each set of parameters in each case contains a plurality of different parameters;– In all the sets of transforming of individual parameters in a suitable value range for the modeling;– Determining the density function for each transformed and not - transformed parameters by means of the plurality of its in the parameters contained etching real isat and usat ions; and– Modeling of the interfering pulse by zufal inexpensive determination of the parameters of the field effect transistor to be modeled on the basis of the pulse reprasentierenden parameter set to the parameters gehorigen density functions and by insertion of the parameters thus obtained in the mathematical function.
