Abstract: Focusing on pure electric vehicle body control Controller Area Network(CAN) bus system, this paper presents a design of application layer protocol based on CANopen protocol. The structure of the pure electric vehicle body control network and the function of each Electronic Control Unit(ECU) are analyzed. The design of the network management, process data objects and service data objects of each ECU and the define of object dictionary are given. A CANopen network simulation platform of pure electric vehicle body control system is designed by CANoe soft and its components CANoe. CANopen. The real node function is simulated by CAPL program and the control panel is designed by Panel Editor software. Simulation results show that the designed pure electric vehicle body control CANopen network meets well the demands of the car door control system.
