【摘要】：随着汽车电子化程度越来越高,整车厂开发的车型中电控单元(行车电脑)的数量越来越多,这些电控单元都通过车载总线网络进行通信和数据交互。通俗来讲,车载总线就像是高速公路,电控单元就像是高速公路上运行的汽车,每辆运行的汽车都必须按照交通法规进行运行,才能避免出现交通事故,否则高速公路就会出现拥堵,甚至瘫痪。因此随着电控单元的增多,对车辆中的CAN总线的安全性、可靠性、以及效率等要求也是越来越高。当前车载总线相关的测试工具主要由国外供应商垄断,不利于国内整车厂的车型研发工作。在车载总线测试工作中,车辆总线仿真是一个至关重要的功能。车辆总线仿真是当车辆在实验室设计研发阶段,车辆上安装的诸多电控单元未研发完成时,通过工具仿真电控单元的功能逻辑,测试车辆总线的功能和可靠性。本课题的ADI车辆总线仿真语言是针对车辆车载总线仿真开发的类C语言,通过开发针对本语言的编译器、模拟器和集成开发环境,为用户提供一套完整的编程环境。ADI语言是在IBM公司提供的LEX、YACC语言词法、语法分析器生成工具生成的分析器基础上,结合编译原理和国内应用要求,对原型代码进行重新架构设计、开发实施,使其更加符合当国内车辆开发测试的应用要求。本课题的工作重点主要有以下几点, (1)在车载总线仿真环境下词法分析其工具(LEX)和语法分析器工具(YACC),语言设计的优化和开发工作； (2)在车载总线仿真环境下对编译器和模拟器进行重构和优化,通过应用更多的标准化函数库提高可靠性和通用性；通过模块化和层次化提高可维护性；通过多线程并发应用,提高整体执行效率。
[Abstract]:With the increasing degree of electronization of vehicles, the number of electronic control units (driving computers) in the vehicles developed by the whole vehicle factory is more and more. These electronic control units communicate and data exchange through the vehicle-bus network. In general, a car bus is like a highway, and an electronic control unit is like a car running on a highway. Every car that runs must be operated in accordance with traffic regulations to avoid traffic accidents. Otherwise, the highway will be congested or even paralyzed. Therefore, with the increase of electronic control units, the security, reliability and efficiency of CAN bus in vehicles are becoming more and more high. At present, the vehicle bus related testing tools are monopolized by foreign suppliers, which is unfavorable to the research and development of domestic vehicle manufacturers. Vehicle bus simulation is a very important function in vehicle bus testing. The vehicle bus simulation is to test the function and reliability of the vehicle bus by simulating the function logic of the electronic control unit when the vehicle is in the design stage of the laboratory and many electronic control units installed on the vehicle are not developed. The ADI vehicle bus simulation language of this subject is a kind of C language which is developed for the vehicle vehicle bus simulation. By developing the compiler, simulator and integrated development environment for this language, To provide users with a complete programming environment. ADI language is based on Lexi YACC language lexical and parser generation tools provided by IBM Company, combined with compiling principle and domestic application requirements. The prototype code is redesigned, developed and implemented to meet the requirements of domestic vehicle development and testing. The main work of this subject is as follows: (1) the lexical analysis tool under the vehicle bus simulation environment (X) and the parser tool (YAC), the optimization and development of language design. Translators and simulators are refactored and optimized, Through the application of more standardized function library to improve reliability and versatility; through modularization and hierarchy to improve maintainability; through multi-thread concurrent applications to improve the overall execution efficiency.
