汽车控制器局域网络技术及应用

On-board Controller Area Network Technology and Its Applications

汽车的电子装备日臻完善,常规的点-点间的布线法使整个汽车的布线变得非常杂乱,对汽车的设计、制造、维护非常不利。本文对汽车中使用网络传输信息的必要性作了阐述,对一种较为成熟的汽车总线——控制器局域网络——的技术特征进行了分析,就其结构和性能同其它网络作了进一步比较。此外,还对汽车网络技术在轿车悬架系统控制的应用研究作了简明介绍。

Electronic devices in vehicles are increasingly improved and sophisticated, the ordinary node-to-node wiring may cause inconvenience and complication to automotive design, manufacturing and after-sale service. The importance and necessity of implementing on-board networks for transferring information are briefly presented. The technical features of a well-developed on-board network, so called Controller Area Network(CAN), are analysed and the comparative study of CAN system is made with other multiplexing system. In addition, the application of on-board networks for electronically-controlled car suspension system is discussed concisely.
