摘要
首先进行了汽车追尾碰撞预警系统总体设计,把系统划分为主控单元、雷达测距单元、信息采集单元和显示-声光报警单元四个子系统;在分析汽车动力学的基础上,提出了系统安全距离模型;对各子系统进行了软、硬件设计;最后,通过模拟试验和实际装车实验,验证了系统所要求的各种性能。
Firstly the master design of the automobile rear-end collision warning system is conducted, the system includes four sub -systems： the main control unit, radar ranging unit, information gathering unit and monitor, sound ＆ light alarm. Based on analysis of the vehicle system dynamics, the safety distance model is brought forward. The software and hardware of system is designed. Finally, based on simulation test and the system processed vehicle experimental test, the system functions validity is proved.
