【摘要】 为了解决车载总线网络间的通信问题,基于CAN(Controller Area Network)网络,设计并实现了一个CAN网关的基本原型。结合CAN总线的特性,实现车载网络的差错控制、流量控制等基本功能。该网关原型用于连接5个子系统网络,既满足子网内部通信的隔离,又实现了子网间数据的正确交换,有效地降低车载网络的数据流量,进一步实现了汽车系统的网络化。更多还原

【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.更多还原
