摘　　要：针对汽车总线多样化以及汽车ECU之间数据交互量大的问题,设计一款以32位微处理器为硬件内核、以AUTOSAR为软件架构,符合MISRA-C嵌入式编程规范,适用于多种通信总线的XCP标定系统。在该标定系统数据交互中,为增加标定系统通用性和代码可重用性,采用符合AUTOSAR通信协议栈的标准接口,实现与AUTOSAR其他协议栈的无缝连接。同时对XCP代码进行QAC检测,提高标定系统代码阅读性。编写Vector CANoe的CAPL脚本程序,进行自动功能测试,检测标定系统功能的完整性。测试结果表明:所设计的标定系统数据交互实时性高、可靠性强。With regard to the diversified automobile bus and the amount of data exchange between ECU, a XCP calibration system that takes 32-bit microprocessor as the core of hardware and AUTOSAR as the software architecture, complies with MISRA-C standard and applicable to various communication buses is designed. In the data exchange of the calibration system, this system uses a standard port suitable for AUTOSAR protocol stack to improve the universality of the system and the reusability of the code, and realizes the seamless connection with other AUTOSAR protocol stacks. Meanwhile, the XCP system's code is detected with QAC method to improve the code readability of the calibration system. A CAPL script program is written based on Vector CANoe, and the automate testing of functional integrity of calibration system is carried out. The test results show that the designed calibration system has high real-time data and strong reliability.
