Research on the Vehicle’s Susceptibility to Complex Electromagnetic Environment

Abstract

With the electric and intelligent development of the automobile industry, the impact of electromagnetic environment on the vehicle becomes increasingly obvious and vehicle manufacturers received a lot of complaints about electromagnetic interference. Traditionally, vehicle manufacturers tried to go to the actual interference environment to investigate the malfunction and try to solve the problems, which is costly and inefficient. In consideration of the inconvenience of field test, a method of scene simulation test in the EMC chamber is proposed to research vehicle’s susceptibility in the complex electromagnetic environment, including the collection and recording of scene signal, the signal playback in the chamber and the vehicle electromagnetic interference test. In the vehicle tests, it is verified that the scene signal has more significant impact on the vehicle by comparing the traditional modulated method, like continuous wave or modulated continuous wave. Through the systematic research, technical support can be provided to the enterprise R&D engineer and technical reserves are prepared for the formulation or revision of related standards.
