Abstract: With the development of automotive intellectualization and network interconnection, higher requirements are put forward for automotive EMC design. In this context, it is necessary to speed up the design methods and means of vehicle magnetic compatibility simulation prediction, integrate electromagnetic simulation prediction into the whole vehicle development process, and reduce the time and cost of later rectification, in order to meet the requirements of electromagnetic compatibility proposed by the new trend. This paper mainly introduces the development status of automotive electromagnetic simulation at home and abroad, and expounds the method of automotive electromagnetic simulation based on FEKO software and the problems found in the simulation process.
