汽车多功能防撞系统设计与仿真

摘要

To overcome the shortcomings of traditional automotive anti-collision system function and expand the target tracking and identification functions, this paper designed a multi-function car anti-collision system by using target detection search theory of tracking while searching radar. It expounded the design goal, function, distribution and system design diagram, established the model, and simulated and analyzed the target detection curve. The predicted curve was consistent with practical curve, and threshold was adjusted by residual error curve in real-time. Simulation results show that the system can realize the predicted goal accurately.%研究汽车防撞系统优化特性,针对传统汽车防撞系统功能过于单一化的缺点,不能准确识别目标.为了拓展对目标的跟踪和识别功能,采用边搜索边跟踪雷达目标探测理论,提出一款多功能汽车防撞系统.阐述了系统的设计目标、功能分配和系统设计框图等内容,建立了探测目标的模型,并进行了目标预测曲线仿真分析.实现多功能防撞系统可获得与实际曲线较一致的预测曲线,并根据残余误差曲线实时调整防撞预处理门限.仿真结果表明,设计的多功能汽车防撞系统可以准确实现目标识别和防撞功能.
