基于超声波的汽车防撞系统（英文）

The automotive anti-collision system based on Ultrasonic

在现有的汽车防撞系统中,主要都是使用雷达进行测距,这类系统的价格较高,不能大面积推广.在现有的汽车防撞系统上优化测距算法,采用超声波传感器进行测距,建立相关的防撞模型,根据不同的测量距离发出不同的报警信息.实验结果表明,在一定范围内报警信息准确.

In the existing system of automobile anti-collision, the radar is mainly used for ranging. However,it canrt be widely used because of its high cost. In this paper,based on the existing system of automobile anti-collision,the ultrasonic sensor is used to measure the distance and establish rele-vant anti-collision model. The experimental results show that the alarming information is accurate within a certain range.
