摘    要
 电子控制燃油喷射发动机被广泛应用于现代汽车上，它的使用大大提高了发动机的综合性能，同时，发动机故障诊断技术的科技含量变得越来越高。因此，研制车辆诊断和保养信息系统就显得尤为必要。
 本文针对目前国内电喷发动机维修过程中存在的问题，结合专家系统的特点，对电喷发动机故障诊断系统的总体结构及其实现的关键技术进行了研究。
 本文阐述了汽车检测技术的发展历史，国内外研究现状以及专家系统今后的发展趋势。借鉴了已开发的发动机故障诊断系统，以Windows XP为操作系统，Visual Basic, Access等为编程语言，应用人工智能诊断方法和面向对象的编程方法，开发了车辆诊断和保养信息系统，它具有友好的人机界面，实现了故障诊断、数据库管理、引导型功能和图解指导四个模块功能。利用ADO技术，研究了数据库管理方法，改善了车辆诊断和保养信息系统的性能和诊断功能。

Development of Vehicle Diagnosis and Maintenance Information System

Abstract
 Electrical fuel injection engine is widely used in modern automobile. It greatly increases integration capability of engine, at the same time, the technology of fault diagnosis of engine demands more and more high technology. So, to develop vehicle diagnosis and maintenance information system for fault diagnosis of engine looks especially necessary.
 Arming at the problems existing in maintenance of electrical injection engine, combining with the characteristics of expert system, the architecture of expert system for fault diagnosis of electrical injection engine and the key technology for its realization are studied in this paper.
 This article elaborated the automobile examination technology historical development, Domestic and foreign research situation as well as expert system present's trend of development. Has profited from the engine diagnosis system which developes. By using Visual Basic and Access etc under Windows XP and applying the diagnosis method of artificial intelligence and the object-oriented programming technology, to develop the fault diagnosis expert system of engine, which has a friendly interface, four functional parts of the fault diagnosis, the knowledge base management, the database management and online training are realized. Using ADO technology, the way of data base management is studied; the performance and the diagnosis function of vehicle diagnosis and maintenance information system of fault diagnosis are improved.
