Abstract:

In order to solve the communication problems between bus networks of a vehicle, a basic prototype of CAN(Controller Area Network) gateway is designed and implemented based on vehicle CAN network. The gateway prototype is used to connect five subsystem networks of car body, satisfying internal communication within subnet and achieving exchanging data between sub-networks accurately.The vehicle network data traffic is effectively reduced. The error control, flow control and other basic functions of vehicle networks are realized by combining the characteristics of CAN bus. Our work practically improves achieving the network system on vehicles.

Key words: CAN, gateway, network management
