某重卡CAN总线控制系统的设计

CAN Body Control System of a Heavy Truck

CAN是一种有效支持分布式控制或实时控制的串行通信网络。本文以某重型卡车为例,遵守J1939协议,通过CAN网络拓扑架构的搭建,展示了车身控制系统的的工作过程和故障诊断过程,论述了CAN总线在商用车重卡领域的应用和CAN在电控系统中应用的经济性、方便性及准确性。通过CAN总线控制系统与传统线束控制对比,体现了CAN总线系统的强大优势。

CAN is a kind of effective support distributed control or real-time control of serial communication network. This paper firstly introduces the development and CAN technology in vehicle control systems, and the advantages of a detailed analysis on the CAN bus carbody control system structure and working principle and the definition of each subsystem. With heavy card tractor carbody control system for example, show the body control system fault diagnosis of the working process and process, simple discusses in commercial vehicle heavy card CAN bus and the application of the field application of electric control system CAN in the economy, convenience and accuracy fully explained. Through a CAN bus control system and the traditional comparative, reflected the wiring control powerful advantage CAN bus system.
