针对高等级公路车辆纵向碰撞事故频发的问题，设计了一种基于DSP的车载测距安全预警系统，该系统通过激光雷达测距传感器实时采集车辆前方障碍物运动状况，由TMS320DM643高速数字信号处理DSP进行主要的数据信息处理，适时解算和分析前方车辆与本方车辆之间的纵向车距是否满足安全车距的需要，利用MC9S12XS128单片机完成车辆行驶状态参数的采集处理及声光预警。实验结果表明，该系统工作可靠性高、价格成本低，具有广泛的应用前景。

For the problems of traffic safety of the highway vehicle longitudinal collision accident , a on-board distance measurement safety warning system is designed, this system real-time acquisition obstacle’s movement before vehicle by laser radar sensor, using the high-speed digital signal processing DSP TMS320DM643 as the platform for primary data information processing, timely calculating and analysis the vertical distance between host vehicle and front vehicle whether meet the needs of the safety vehicle distance, using MC9S12XS128 MCU to complete the acquisition and processing parameters of vehicle operation and sound and light warning. The experimental results show that high reliability work and low cost price of this system has broad application prospects.
