摘要
介绍了FlexRay总线技术的发展特点及克斯菲尔公司生产的FlexRay总线控制器芯片MFR4200,阐述了汽车线控制动技术的主要特点,详细论述了基于嵌入式微处理器芯片S3C44B0X的汽车线控制动系统的设计;构建了线控制动系统节点,设计了系统硬件软件,使用FlexRay总线总线数据检测软件检测总线数据;结果表明用FlexRay总线构成的嵌入式汽车线控自动系统较其他的总线系统具有良好的数据传输稳定性及可靠性,同时很好地实现了汽车的制动。
Introduced the FlexRay bus technology development and characteristics of the production company Freescale FlexRay bus controller chip MFR4200, expatiated the main characteristics of technology of Brake--By--wire on the car, discussed in detail based on embedded microprocessor S3C44BOX vehicle brake wire system design. Constructed the Brake--By--wire system nodes, designed the system hardware and software, used the FlexRay bus data detection software testing data. The results showed that use of a bus embedded FlexRay automotive wire automated system other than the bus system has a good stability and reliability of data transmission. At the same time achieve a very good vehicle braking.
