毕业设计(论文)常州机电职业技术学院毕业设计（论文）作者：许陈陈学号：30821236系部：汽车工程系专业：汽车电子题目：汽车导航仪故障诊断与分析指导者：张红党评阅者：2010年12月毕业设计（论文）中文摘要汽车导航系统是在全球卫星定位系统GPS基础上发展起来的新型技术。驾车者只要将目的地输入汽车导航系统，系统就会根据电子地图自动计算出最合适的路线，并在车辆行驶过程中（如转弯前）提醒驾驶员按照计算的路线行驶。今天，车用导航系统在日本已基本实现普及，在美国和欧洲的市场增长也是一日千里。随着宽带网和移动网的普及应用．GPS，GIS／GSM的综合应用必将迅速推广，属于ⅡS核心技术之一的GPS车辆导航系统将有更多机会开辟新的更为广阔的国内市场。本文讨论了基于GPS的汽车导航系统的原理和现状，对导航仪的常见故障进行分析和诊断。关键词：汽车导航仪结构原理故障分析诊断展望毕业设计（论文）外文摘要Title：CarNavigatortroubleshootingandanalysisAbstract：CarnavigationsystemisintheglobalpositioningsystemGPSdevelopedonthebasisofnewtechnologies.Driversaslongasthedestinationforcarnavigationsystem,systemswillbebasedontheelectronicmapautomaticallycalculatethebestrouteandvehicledriving(suchasturningtheformer)remindsthedriverroutesinaccordancewithcalculation.Today,carnavigationsystemsinJapanhasbeenbasicallyachieveuniversal,intheUnitedStatesandtheEuropeanmarketisalsogrowingbyleapsandbounds.Asbroadbandandmobilenetworksofuniversalapplication.GPS,GIS/GSMintegratedapplicationwillpromptpromotion,belongstooneofthecoretechnologySⅡGPSvehiclenavigationsystemwillhavemoreopportunitiestoopenupanewbroaderdomesticmarket.ThisarticlediscussesthebasedonGPScarnavigationsystemstatusoftheprincipleand,onthecommonNavigatorforanalysisanddiagnosisoffaults.Keywords：carNavigatorstructureprinciplefailureanalysisdiagnosticperspective.目录1绪论............................................................................................................................11.1汽车导航仪简介及其工作过程............................................................................................21.1.1汽车导航仪概念................................................................................................................21.2汽车导航仪的工作过程........................................................................................................21.2.1用户输入目的地................................................................................................................21.2.2行驶路线的计算................................................................................................................31.2.3行驶中的导航....................................................................................................................31.3本章小结................................................................................................................................42汽车导航仪结构和工作原理.........................................................................................52.1全球定位系统........................................................................................................................52.1.1全球定位系统的定义........................................................................................................52.1.2卫星定位系统....................................................................................................................62.2导航仪的组成和工作原理...................................................................
