摘要
在中国四轮定位仪处于产品成长时期,大部分厂家是贴牌生产或是和国外厂家合作授权生产,有的甚至盗用国外技术生产,而真正拥有研发能力的国内厂家不超过五家。
国内自行研发的四轮定位仪以PSD测量方式较多,D测量方式,当然掌握此项技术的厂家就极少。对于上位部分,据可靠调查,目前在国内外所有的产品都是使用PC作为上位机,这是导致四轮定位仪体积庞大的原因。
本文针对我国汽车四轮定位仪的现状,研究出一种基于ARM的汽车四轮定位系统,D测量技术,加速度传感器测量技术,红外通信技术。上位机部分,本系统采用了嵌入式ARM+Linux+QT平台,实现了人机交互。
本文研制的汽车四轮定位仪是拥有自主知识产权的高端检测仪器。本文嵌入式技术的成功运用,将成为汽车四轮定位仪发展的必然方向,并将会对中国汽车安全做出重要贡献。

Abstract
In China, car wheel alignment is in its stage of developing period. Many factories are OEMs (Original Equipment Manufacture) or cooperators, even stealing technology panies aboard. At home, Less than five factories can design their own production.
The four-wheel alignment device based on PSD takes up the main market in China. These D technology takes up only a small market, as well as few factories that own this technology. According to survey, as to host machine, all factories home and aboard adopt PC to be host machine, which causes the wheel alignment system takes up large place.
According to the current development of wheel alignment system, a new wheel alignment system based on ARM is designed, including technology D, MMA, munication and embedded technology in ARM supported by Linux and QT.
The system is registered with self-owned intellectual property rights. With the essful application of embedded technology in this system, it will direct the future development of car wheel alignments and it will make great contribution to the safety of car industry.
Key words: for-wheel alignment, Bluetooth, CCD, MMA6260Q
