Numerical EMC-Simulation for Automotive Applications

New electronic systems accompany most of the technical innovations in automotive industry. In consequence of the growing number of electrical equipment the electromagnetic noise level is rising in automobiles. The increased electromagnetic emissions however raise the risk to miss EMC standards and perturb the functional integrity of new and existing electronic systems. Hence, mastering of potential EMC problems in new automobiles becomes increasingly important to the car industry. Numerical simulation is an important key for the detection and rejection of potential EMC problems early in the design process. This paper presents a continuous concurrent EMC simulation process based on the exchange of EMC models between car manufacturer, electronic supplier and IC developer. The described process fundamentally influences the introduction of new technologies in a vehicle by cutting the risk of EMC-failure and avoiding costly and time-consuming redesigns.
