随着我国汽车产业的不断发展以及人民生活水平的不断提高,汽车已经走进了越来越多的家庭,在汽车给我们的出行带来方便的同时,一方面造成交通的不断拥挤,另一方面由汽车倒车而产生的安全问题也日益突出,据调查在2002年汽车事故的发生比例中,倒车引起的事故占21%,到2006年,倒车引起的事故占28%,到2008年甚至到达了30％.因此,研究一款高性能的倒车辅助装置是很有必要的.
本文详细阐述了汽车倒车雷达的硬件和软件设计过程.硬件部分主要介绍主板的设计,显示器的设计及超声波测距系统的原理等.软件部分采用模块化设计思想,主要分为主程序,测距模块,声音报警模块,显示模块由单独的单片机控制,并由主程序对各模块进行调度管理.
最后对系统的软硬件进行了实验测试,测试表明该系统在30—7500px范围内有较好的准确性,并且能够按设计要求实现LCD显示倒车距离跟声音报警功能.本系统具有集成度高,成本低,系统稳定等优点,对驾驶员倒车具有一定的帮助使减少倒车事故的发生,所以本课题的研究具有一定的理论和实用价值.

With the continuous development of China's automobile industry and
the continuous improvement of people's living standards,cars have entered more
and more families,while cars bring convenience to our travel,on the one hand,
traffic congestion,on the other hand produced by reverse and security issues
are also increasingly prominent,according to the survey in 2002 car accident
proportion,reversing caused by accidents accounted for 21%,to 2006,reversing
caused by accidents accounted for 28%,even reached 30% by 2008.Therefore,
research a high-performance astern auxiliary device is necessary.
This paper expounds the hardware and software design process of car
reversing radar.Hardware part mainly introduces the design of the main board,
the design of the display and the principle of ultrasonic ranging system,etc.
Software part adopts the modular design idea,main points and main program,
ranging module,voice alarm module,display module by a separate single chip
microcomputer control,and the main program for scheduling management module.
Finally,the hardware and software system has carried on the
experiment test,the test shows that the system is in the range of 30-7500 px
has good accuracy,and can according to the requirements of design distance with
LCD display astern voice alarm function.This system has high integration,low
cost,stable system,etc,for the driver reversing back has certain help to
reduce the happening of the accident,so this topic research has certain
theoretical and practical value.
