Research on CAN Bus of Pure Electric Vehicles Based on SAEJ1939

Abstract:

The use of CAN bus network on electric vehicles is of great significance, it can not only greatly reduce the costs of electric vehicles, but also increase the driving distance of electric vehicles. The stability of CAN bus load rate and CAN network communication rate plays a vital role to the CAN network，by studying and making use of SAEJ1939, this paper develops a vehicle network topology, then through calculating the bit rate of transfer time to calculate the load rate, combined with using the software named CANoe from the Vector company in Germany to analyse and simulate the sending cycle of each CAN bus node on pure electric vehicles. In this way,this paper analyses the reasonableness of CAN network design of the vehicle body. Finally this paper applies the on-site verification to prove the reliability of simulation results. This study is based on SAEJ1939 agreement CAN2.0B, did not make a study for CAN2.0A, so there are limitations, the findings may not apply to CAN2.0A.
