摘 要
隨著我國(guó)汽車保有量的不斷增加，汽油、柴油等非再生資源的逐漸減少，加之環(huán)境保護(hù)意識(shí)的逐漸加強(qiáng)，使人們更加關(guān)心車輛油耗，而且要求限制車輛用油量的呼聲也越來越強(qiáng)烈。開發(fā)能快速、準(zhǔn)確測(cè)量汽車在各種工況下的油耗的新技術(shù)，已成為一項(xiàng)重要的課題。
本文在分析和總結(jié)目前國(guó)內(nèi)外車輛油耗檢測(cè)儀器普遍存在的問題的基礎(chǔ)上，根據(jù)油耗檢測(cè)技術(shù)現(xiàn)有的技術(shù)水平和發(fā)展趨勢(shì)，采用單片機(jī)技術(shù)，研制基于容積法的汽車油耗檢測(cè)儀器。主要內(nèi)容包括汽車油耗快速檢測(cè)儀器的硬件選擇與設(shè)計(jì)，系統(tǒng)控制電路的設(shè)計(jì)構(gòu)建汽車油耗智能檢測(cè)系統(tǒng)，建立汽車油耗檢測(cè)的數(shù)學(xué)模型，根據(jù)儀器功能要求進(jìn)行軟件的選擇與設(shè)計(jì)，最后選擇語言編寫控制程序。

ABSTRACT
With the cars in the ever-increasing, petrol, diesel and other non-renewable resources gradually reduced, in addition to the gradual strengthening of environmental awareness, it is more concerned about fuel consumption of vehicles, vehicle fuel consumption to limit the voices have become stronger and stronger. To develop rapid, accurate measurement of vehicle fuel consumption in various operating conditions of the new technologies, has become an important topic.
In this paper, analysis and summary of vehicle fuel consumption at home and abroad the issue of widespread detection technique based on the fuel consumption of detection technology and the technological level of existing development trends, the use of single-chip technology, the development of intelligent vehicle fuel consumption testing software. Include motor vehicle fuel consumption to build mathematical model of intelligent detection systems, detection systems based on vehicle fuel consumption and the mathematical model of the design of vehicle fuel consumption testing software and software unit testing and integration testing, the overall test hardware. At the same time, the system anti-jamming measures.
Intelligent vehicle fuel consumption testing of software delivered by calculating the fuel flow sensor flow pulse signal, can measure the fuel consumption of motor vehicles 100 kilometers.
Key words：Fuel consumption; Single chip; Assembly language; Design
