Design of CAN Network Communication Protocol for Pure Electric Commercial Vehicles

【Abstract】This paper based on SAE J1939，CAN communication protocol of pure electric commercial vehicle is designed. According to the controller characteristics of pure electric commercial vehicles，the CAN network topology is designed，CANID is defined according to the interactive information between controllers，load ratio is calculated，and load ratio and communication quality are tested in real vehicles，which has practical reference significance for CAN network design of new energy commercial vehicles.

【Key words】pure electric commercial vehicle;CAN;communication protocol
