【摘要】 通过分析换道时车辆的运动关系,使用最小安全距离作为安全换道的指标,并将安全车距的计算与车辆的当前速度,到达临界碰撞点的时间,两车的相对速度、加速度关联起来,研究了车辆碰撞的条件,给出了换道最小安全距离的计算方法,并进行了仿真与分析。本文的研究结果为下一步的自动换道辅助系统和自动超车辅助系统的研究奠定了理论基础。更多还原

【Abstract】 Using the minimum safety spacing(MSS) as an index of the safe lane-changing of the vehicle, the kinematics of the vehicle involved in lane-changing maneuves was analyzed. The computation of MSS was correlated with the current vehicle velocity, the time searching the critical collision point, the relative velocity and relative acceleration between both vehicles to seek the conditions for vehicle collision avoidance, and the calculation method for MSS at lane-changing process was accomplished and associated simulation and analysis were performed, laying a necessary foundation for further research and development of the autonomous lane-changing and overtaking assistance systems.更多还原
