Vehicle virtual instrument interface, is the main interface that driver gets condition data of automobile. It is convenient for driver to realtime to grasp the working conditions of automotive, effective humanputer interaction and the automobile has the vital significance to guarantee safe and stable running of the car. At present, Windows CE and the Linux operating system are in widespread use. Windows CE operating system has a stable function and perfect technical support,.But the price is expensive and the source code is closed. It also has fewer useful resources from work. Maximum advantage of Linux operating system is free and open source. It is the mainstream operating system of the vehicle information displayed system. But it is not based on the mobile device development and it cannot meet the demands of mobile equipment. Android is developed by Google and it is based on open source mobile platform and open source operating system Linux. For the current, mainstream embedded platform supports well. Superior performance of the Android system has been validated in a variety of mobile devices. It includes the operating system user interface and application program. In order to enhance munication between people and vehicles and improve the friendly interface of people and vehicles,we can view the automobile dashboards and other data can be displayed and other functions in the Android mobile phone platform . Car dashboard reflects a variety of parameters during the process of the car. We can observe the engine speed， vehicle speed, temperature, time, mileage and other realtime information on the Android platform. We can detect and notify the user about the fault encountered in order to improve the performance about safety and use. Keywords: Android platform。 Dashboard。 Eclipse 4 目錄 第一章 緒言 ................................................................ 6 研究背景及意義 ...................................................... 6 課題的主要工作 ...................................................... 6 第二章 汽車儀表盤概述 ...................................................... 8 基本介紹 ........................................................... 8 ............................................................ 8 指示燈和警報(bào)燈 —— ................................ 9 ................................................. 10 ..................................................... 10 ................................................. 10 5 驅(qū)動(dòng)防滑控制指示燈 ............................................... 11 ................................................... 11 ..................................................... 12 ....................................................... 12 硬件系統(tǒng)結(jié)構(gòu) ...................................................... 13 一 . 單總線結(jié)構(gòu)折疊 ................................................. 13 二 . 雙總線結(jié)構(gòu)折疊 ................................................. 13 三． 采用通道的大型系統(tǒng)結(jié)構(gòu)折疊 .................................... 13 CAN模塊 ........................................................... 14 一、 介紹 ......................................................... 14 二、 功能概述 ..................................................... 14 三、 功能特點(diǎn) ..................................................... 14 四、 運(yùn) 用情況 ..................................................... 14 第三章 系統(tǒng)開發(fā)工具概述 .................................................... 15 Eclipse 簡介 ....................................................... 15 ..................................................... 15 Android目錄結(jié)構(gòu)說明 ............................................... 16 Android 系統(tǒng)架構(gòu) ................................................... 17 Android 應(yīng)用程序概念性描述 ........................................ 17 應(yīng)用程序的組成部分 ............................................... 18 一、 Activity ...................................................... 18 二、 Intent Receiver ................................................ 19 三、 Service ....................................................... 19 四、 Content Provider ............................................... 20 應(yīng)用程序的生命周期 ................................................. 20 1． 活動(dòng)的生命周期 ................................................. 21 2． 服務(wù)的生命周期 ................................................. 22 3． 廣播接收器的生命周期 ........................................... 22 第四章 圖吧汽車衛(wèi)士 ...................................................... 23 簡介 .............................................................. 23 功能 .............................................................. 23 相關(guān)界面 .......................................................... 24 5 第五章 終端軟件儀表盤的實(shí)現(xiàn) ................................................ 25 簡介 .............................................................. 25 南郵衛(wèi)士的源文件結(jié)構(gòu) ............................
