摘要

摘要: 紧急情况下驾驶员通常会依据驾驶风格进行转向、制动或二者组合的避障操纵.利用Frecord数据采集系统、制动踏板力传感器、位移传感器及动态GPS研究紧急避障时驾驶员制动操纵随时间的变化规律以及最大制动踏板速度与车距障碍物距离、行驶车速的关系.试验结果表明,紧急避障时制动操纵通常经过4个阶段,一定行驶车速下最大制动踏板速度与车距障碍物距离呈负幂次关系;一定车距障碍物距离下最大制动踏板速度与行驶车速呈正相关线性关系;并且给出了相应的回归曲线.对紧急状况下驾驶员制动特性进行研究有助于更好地理解驾驶员行为,也可为驾驶员安全管理提供理论依据.

Abstract: Drivers are used to steering, braking or steering-braking when they meet obstacles in order to protect lives and properties. Frecord data collecting system, dynamic GPS and sensors of braking force and angles are utilized to study the changing rules of drivers' braking velocitiy according to different time, the relation between maximum braking velocity and the distance between vehicle and obstacle, as well as driving velocity. The results show that drivers' braking operation includes four periods and also indicate that the drivers' maximum braking velocity is changing with distance in negative-power, however drivers' maximum braking velocity is changing with driving velocity in positive-linear. The regressive formulas are given. This research can help us to understand drivers' behavior under emergency and also offer theory basis for drivers' safety management.
