摘要
首先根据车辆实际运行环境,结合各车的初始横向位置,对换道车与各相关车辆碰撞临界时间顺序进行分析。然后,基于换道车与周围各车的相对速度、相对加速度以及换道车的几何尺寸建立换道车初始纵向安全距离的换道模型。最后,运用Matlab对不同碰撞临界时间顺序的换道模型危险态势进行仿真分析,从而得到各状态下换道车的初始纵向安全距离。
Firstly, in combination with the initial lateral position of each vehicle, the critical time sequence of the vehicle and the surrounding vehicle is analyzed according to the actual operating environment of the vehicle. Then, based on the relative speed, the relative acceleration and the geometric dimensions of the lane-change vehicle, the model of initial longitudinal safety distance is established. Finally, Matlab is used to analyze the lane-changing models which are considered the critical time order of different collision, and the initial longitudinal safety distance of the vehicle is obtained in each state.
