摘　　要：FlexRay极有可能成为下一代车用网络标准,为了研究FlexRay在汽车线控系统上的应用前景,本文提出了基于FlexRay的线控制动系统解决方案。这个原型系统由4个轮速传感器、3个ECU单元,1个步进电机,1个制动踏板位置传感器组成,开发流程采用了V模型。从运行情况看,系统实现了在高速的情况下进行双通道容错实时通信,相对其它总线系统,本系统具有良好的数据传输稳定性及可靠性,线控制动效果显著。FlexRay will probably become the next generation vehicle network standard. This paper presents a FlexRay based solution to a brake-by-wire pre-prototype system to investigate its application prospect in a x-by-wire system. This pre-prototype comprises 4 speed sensors, 3 ECU units, I step motor and 1 footbrake pedal position sensor. The development flow follows a V model. We implement fault-tolerant and real-time high-speed dual channels communication in its operation. Result shows that the system has better data transmission stability and reliability than other bus based system, and that brake effect is obvious.
