Investigation of Engine Based Electromagnetic Interference for Electric Vehicular Communications Systems

Abstract

The transient effect of electromagnetic interference (EMI) produced by electronic equipments has been extensively studied. However, for the electric vehicles, speed changing also introduces considerable amount of interference. In this paper, we study the EMI influences, which include the interferences caused by the electronic switch and the vehicular engine, on the electric vehicular communications systems. The transmission quality of various standards is investigated, including FlexRay, and Control Area Network (CAN).
