激光测距技术在汽车主动安全装置中的应用研究

The Research on Laser Range-Finding Technology in Vehicle Active Safety Device

探讨一种基于激光探测技术的汽车主动安全报警系统装置。并通过模拟系统试验来检验此装置的功能,测试系统的性能。试验结果表明在输入不同的报警距离与制动距离时,均能实现不同方式的报警,从而提醒驾驶员注意并采取减速或制动措施,达到有效预防追尾碰撞事故发生的目的,提高了汽车的主动安全性能。系统工作稳定,报警距离值的选取符合法律规定,且准确率高,具有一定的实用价值,以及广阔的推广应用前景。

Discussing a vehicle active safety device based on laser range-finding technology,testing its function and performance by a analog system. The test result indicated that it can achieve different ways of warming, when inputting different data between wanning distance and braking distance. Then it can remind the driver to reduce the speed or take braking action to achieve the purpose of preventing behind collision accident and improving the car＇s active safety performance. The system has stability,high accuracy,certain practical value and broad application prospect,alarm distance meet the law.
