Risk-based EMC System Analysis Platform of Automotive Environments

Abstract

Constantly on-going changes in new technologies applied in modern vehicles introduce many challenges in the automotive electromagnetic compatibility engineering. So far, the currently implemented EMC requirements and methods present sufficient performance. However, they do not illustrate thoroughly an actual automotive environment. They tend to focus on the EMC validation of each system individually without always considering other possible influential factors and coexisting systems. Aim of this paper is to introduce an EMC system investigation platform using a simplified model that demonstrates an automotive environment in order to point out the importance and scale of significance of various parameters. In this paper, the structure of the introduced three-point model is first described and explained. Then, experiments are presented in order to point out the influence of selected macro-parameters. Finally, suggestions for further extension of the model through Monte Carlo simulations are proposed with a brief presentation of a modelling procedure.
