基于AUTOSAR标准的车辆电气系统CAN通信协议栈研究

摘要

AUTOSAR is a open software architecture standard in automotive E/E system.On the basis of full study and research of AUTOSAR structure,the CAN Communication Protocol Stack was developed with hierarchy and standardization,also loaded and tested on the micro controller of MC9S12XEP100.The results prove that the Protocol Stack can greatly realize communication between different layers of CAN,which can meet the requirements of Vehicle bus communication;it is also capable of compatibility and transportation,which can observably increase the code transporting speed between different hardware platforms,decrease the software developing time and also increase the code reliability.%AUTOSAR是面向车辆电子电气领域的开放式软件体系架构标准;在充分学习研究AUTOSAR软件体系标准的基础上,开发了具有层次化、模块化、标准化接口的的CAN底层通信协议栈,并在飞思卡尔16位微控制器MC9S12XEP100的平台中进行了加载测试;测试证明该协议栈能够很好地实现CAN总线各层间的通信,能够满足车辆电子电气系统对总线通信方面的要求,具有较强的兼容性和移植性,可以显著地提高不同硬件平台间软件代码的移植速度,节省了软件开发时间,提升了软件代码的可靠性.
