Abstract: The paper introduces the application of CAN bus in the Hybrid Electric Vehicle, studies the CAN bus technique and the design based on the node of CAN bus. The network control architecture of electric vehicles based on CAN bus was constructed, in which regional autonomy, function distribution and hierarchy methods were adopted. Network control unit and in vehicle gateway were designed, and transmitting methods and properties of data in the network were discussed, and provides a network topology mode. The theories foundation and basis for new generation automotive are provided, which are combined to introduce the hardware constitutes and software method for the node of CAN bus. This architecture might reduce difficulties in installation and maintenance, improve the system reliability and real-time of manipulation, and obtain the reasonable distribution of energy.
