基于ARM的CAN总线汽车控制系统的研究

Study of CAN auto-mobile controlling system based on ARM

采用ARM作为汽车计算机控制系统中的主控制器并兼作网关,利用ARM的高性能和可裁减性构建高低速CAN总线通信控制网络和仪表控制,实现了全部节点之间的数据共享以及相互之间的协同工作,并可在不同节点间实现高效数据传输。

CAN plays a role of communicating, exchanging information between ECUs in car. So many information points show that there are high and low bus speed. This paper studies that taking advantages of ARM＇s high performance and modification, using ARM as the car information controler and netgate. We could share data and all cells could work in coordination, which can improve bus efficiency.
