| 摘要: |
| 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. |

| Abstract: |
| In the existing system of automobile anti-collision,the radar is mainly used for ranging.However,it can't 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 relevant anti-collision model.The experimental results show that the alarming information is accurate within a certain range. |
| Key words: the system of automobile anti-collision ultrasonic sensor the algorithm of ranging |
