摘 要
随着社会经济的发展，汽车已经深入人们的日常生活，私家车的数量急剧增加。汽车油耗支出已经成为日常消费很重要的一项组成。更多的人关心自己的汽车平均油耗，而汽车油耗的准确计算相对比较复杂，很多汽车没有提供具体的数据记录和分析功能，所以采用智能手机这一非常普遍的计算设备提供快捷、方便、直观的油耗记录和统计分析功能成为非常实用可行的方案。
本文介绍了手机操作系统Symbian OS的特点和设计特点，设计并实现了一个运行于Symbian操作系统下S60平台的汽车油耗分析工具。它能帮助车主记录每次加油的情况，保存到数据库中，同时对数据进行统计分析，为车主提供快捷、方便、直观的油耗参考。文章首先介绍了本课题的背景，分析了该研究的必要性以及软件的实用性。接着，对论文运用到的关键技术进行深入研究。了解了这些关键技术后，本论文描述了汽车油耗分析工具的功能分析与设计，对系统的需求、功能分析以及系统设计模式以及软件算法等进行了详细论述。接着，对软件的实现进行了介绍。最后分析了实验的结果，并对该项目进行了总结和展望。

Fuel Consumption system analysis tool
Abstract
As social and economic development, cars have become deeply in people’s daily lives, in the number of private cars increased quickly. Gas expenditures have become a very important component of daily consumption. More people are concerned about their average gas expenditures of cars, gas consumption and the exact calculation of relatively complex, Many vehicles failed to provide specific data recording and analysis functions, And smart phone is a common computing equipment which can provide fast, convenient and visual record gas consumption and statistical analysis functions as a very practical and feasible option.
This paper introduces the cell phone operating system Symbian OS features and design features, Design and implementation of a run on the Symbian operating system S60 platform vehicle gas consumption analysis tools. It will help the owners of record of each refueling, the preservation of the database, and the data for statistical analysis, as the owner provides a fast, convenient and direct reference to the fuel consumption. The article first introduced the subject of the background of the study and the need for software utility. Then, the thesis that the use of key technologies for in-depth study. Understanding of these key technologies, this paper describes a car gas consumption analysis tool functional analysis and design of the system demand, Functional analysis and system design and algorithm algorithms for a detailed exposition. Then, the realization of the software was introduced. Finally, it’s the experimental results of the project and a summary and expectation.
