| 摘 要： | 为有效预防车辆追尾事故的发生,基于系统动力学理论构建了车辆追尾事故模型,设计了车辆追尾预警系统;该模型充分考虑了驾驶员人体反应时间及信息处理过程的时间延迟,跟驰车辆可以根据引导车辆车速的变化及自身车速的变化计算是否会发生追尾事故,系统将在可能发生追尾事故时给出预警信号;详细给出了模型的构建过程和预警系统的工作原理、结构组成、硬件电路设计,以及软件设计;系统试验运行良好,可靠性高,成本低,具有广阔的应用和推广前景。

| Abstract: | In order to prevent vehicle rear-end accident,a model of rear-end accident based on system dynamics theory was proposed,and a beforehand alarm system against vehicle rear-end accident was designed.Driver's physical reaction time and perception process were involved in this model,and after calculating the system installed in the following vehicle can predict whether the rear-end accident will occur.In case that the rear-end accident may occur,the system will give an alarm.In the paper,the model's establishme... |
