| 摘 要： | 驾驶员反应时间受多种因素影响，存在模糊性与随机性，本文中对一些实验数据进行拟合归纳，得出分心驾驶条件及正常驾驶条件下反应时间的概率密度函数，使用模糊物元分析法确定了适应于各年龄人群的反应时间概率密度函数。在此基础上，根据车速及年龄条件，将反应时间进行归类划分和区间细化，分析了适宜于不同年龄、车速且在考虑分心驾驶状态下的安全车距，并研究了更符合实际行车状况的防碰撞安全车距模型。

| Abstract: | Reaction time of drivers is affected by multiple factors, which has randomness and fuzziness. In this paper, the experiment data was fit and summarized to find the probability density function of drivers＇ reaction time under distracted and normal conditions. The fuzzy matter-element analysis method is used to find the probability density functions of reaction time which are adapted to every age group. On this basis,, the reaction time is classi- fied, divided and refined to intervals according to speed and age, then the safe distances under different ages and speeds ,with condieration of the distracted driving, are analyzed, and the safe distance model, which is more suitable to the actual, is studied. |
