Auto-Network Design Based on the CANopen Protocol in Electronic Vehicles

A network based on the CANopen protocol was designed to resolve the communicating problem of each part in the Electronic Vehicle(EV).The realization of its requirement of hardware and software was put forward.The communicating mechanism and criterion of the CAN network were introduced.Each node based on the micro-controller PIC18F4685 and the high-speed CAN bus driver MCP2551 were developed.
