摘要
本文在深入学习FlexRay总线的基础之上,研究分析汽车发动机控制系统的构成,并提出一种用FlexRay总线来实现对其控制的设计。文中采用飞思卡尔高性能单片机MC9S12XF512,独立通信控制器MFR4310和FlexRay总线驱动器TJA1080,给出电路整体设计方案及软件设计流程,对汽车FlexRay总线的发动机控制系统节点开发具有一定的参考价值。
A design of automobile engine control system was proposed based on the research of FlexRay bus and automotive engine control system structure.Freescale＇s high-performance singlechip MC9S12XF512,communication controller MFR4310 and FlexRay bus driver TJA1080 were adopted,and the overall circuit design and software design process were given.There＇s a certain reference value for the FlexRay bus node development of engine control system.
