摘　　要：以降低交通事故的发生为目标,建立更加准确并适合不同驾驶员驾驶特征的安全车距数学模型,设计基于数字信号处理器(DSP)和单片机(MCU)的双CPU结构的控制模块,给出DSP与MCU通信、电源系统、报警显示等硬件设计及系统主程序流程。对系统进行仿真实验,结果表明该系统性能稳定,运行良好,具有较强的实际应用价值。In order to reduce traffic accident, we set up a more accurate and suitable safety-distance model for different driving characteristics, design a control module with dual-CPU architecture based on DSP and MCU, and accomplish hardware design of communications between DSP and MCU, power-supply system,alarm display and the design of system work software. System testing shows that this system has stable performance and works well so that it has strong practical application value.
