FlexRay bus has a better real time performance and a better reliability as a new control bus in-side the vehicle. After the analysis of FlexRay bus,this paper aimed to solve the problem of EMC of elec-tric communication system based on TMS320F28335,MFR4310 and TJA1080. We established a method which can improve the EMC performance of the whole FlexRay sections by adding a digital isolator,com-mon mode chokes and a separated termination into the section drive circuit of FlexRay.
