Abstract: In the past few decades, on-board electronic devices have been developingtremendously in automotive industry, and it is believed that the trendof electrication and autonomous driving will sustain in the near future.Thus, passenger cars are going to suer from more severe electromagneticenvironment, especially from an EMC's perspective.This thesis is an investigation and overview on a possible simulationmethod applied to vehicle radiated immunity test in accordance withISO 11451-2 standard. The preliminary work of geometry clean-up onthe model obtained from structural dynamics department and the overallmethod development have been discussed. The main contribution of thisthesis is to build up a feasible workow that is suitable for vehicle EMCsimulations based on FEM electromagnetic simulation software ANSYSHFSS. In addition, some potential future work within this area is alsosuggested by the author.
