| 摘 要： | 为了解决在综合化车辆信息系统软件构件化开发平台中,中央处理机与各采集、执行系统之间的数据通信问题,提出一种基于配置解析的FlexRay通信方法.首先对FlexRay总线通信原理进行分析,利用数据的可存储、可配置等特性将FlexRay总线协议的信息参数配置为XML文件;然后通过总线解析软件,将总线信息对应到相应的编码中,各个软件构件可直接通过编码获得总线信息;最后以实验室仪表盘仿真为例,验证了该方法的可行性.

| Abstract: | A method of FlexRay communication based on XML file parsing was proposed to solve the problem of the communication between Center Core Processor Computer and the acquisition or executive system above the embedded component-based software platform in the vehicle information system.First, the principle of FlexRay was analyzed and the bus parameters in an XML file were described with their storability and configurability.The bus information was associated with corresponding IDs after the parsing.Every software component can get the desired information through the IDs.Finally,the method was proved to be feasible and effective by simulation of vehicle meters in the laboratory. |
