【摘要】：嵌入式系统应用越来越广泛,其软件规模也在不断扩大,随着人们对汽车多功能需求的提高,汽车电子领域软件控制系统日趋复杂,为了提高软件开发效率,缩短开发周期,软件系统的可维护性和可移植性变得更为重要。本文以汽车电子领域的板级支撑包为设计目标,参照AUTOSAR规范设计符合要求的板级支撑包,并将所设计的板级支撑包应用于车身控制模块(BCM)软件系统,进行硬件测试和分析。针对汽车电子的应用特点,本文所设计的板级支撑包采用层次化、模块化的结构设计方法,包含一套统一的硬件抽象接口函数和可配置的底层驱动库,实现上层软件的平台无关性,提高软件的可移植性。同时参照欧洲的汽车开放式系统架构AUTOSAR标准进行设计,使得板级支撑包具有良好的扩展性。本论文的主要内容包括： 1.分析汽车电子软件的发展现状,现存问题及发展趋势,并参阅最新的AUTOSAR标准,重点研究硬件抽象相关部分。 2.参照AUTOSAR标准,按照层次化、模块化的架构设计了板级支撑包。板级支撑包层次上划分为微控制器抽象层和ECU抽象层。微控制器抽象层包括IO驱动模块、存储驱动模块、通讯驱动模块和微控制器模块,ECU抽象层包括IO抽象模块、存储抽象模块、通讯抽象模块和ECU抽象模块。 3.板级支撑包应用于BCM软件系统,详细分析了在该硬件平台上实现板级支撑包应完成的具体工作。并在车身电器台架上对BCM进行功能和性能测试,最后分析了应用效果。参照AUTOSAR规范的板级支撑包设计方法,使得软件具有高复用性和高可靠性,有效实现了操作系统等上层软件与底层硬件的无关性。
[Abstract]:The application of embedded system is more and more extensive, and its software scale is expanding constantly. With the improvement of people's demand for multi-function of automobile, the software control system in automobile electronic field is becoming more and more complex. In order to improve the efficiency of software development and shorten the development period, The maintainability and portability of software system become more important. The designed board support package is applied to the body control module (BCM) software system, and the hardware is tested and analyzed. In view of the application characteristics of automotive electronics, the board support package designed in this paper adopts a hierarchical and modular structure design method, which includes a set of unified hardware abstract interface functions and configurable bottom driver library. The platform independence of the upper software is realized, and the portability of the software is improved. At the same time, according to the AUTOSAR standard of the automobile open system architecture in Europe, the board support package has good expansibility. The main contents of this thesis are as follows:. 1. Analyze the current situation, existing problems and development trend of automotive electronic software, and refer to the latest AUTOSAR standard, and focus on hardware abstraction. 2. According to the AUTOSAR standard, according to the hierarchical and modular architecture, the board level support package is designed. The board level support package is divided into microcontroller abstract layer and ECU abstract layer. The microcontroller abstract layer includes IO driver module, storage driver module, and so on. The communication driver module and the microcontroller module include IO abstract module, storage abstract module, communication abstract module and ECU abstract module. 3. The board support package is applied to the BCM software system, and the concrete work to realize the board level support package on the hardware platform is analyzed in detail. The function and performance of BCM are tested on the body electric appliance bench, and the application effect is analyzed at last. Referring to the board support package design method of AUTOSAR specification, the software has high reusability and high reliability, which effectively realizes the independence of the upper software such as the operating system from the underlying hardware.
