The invention relates to a vehicle speed planning method and system. The vehicle speed planning method comprises the steps of obtaining motion state data of a vehicle and one or more adjacent vehicles; acquiring map environment data, wherein the map environment data comprises data of a lane where the vehicle is located and data of left and right adjacent lanes; judging whether a lane changing demand exists or not based on the motion state data and the map environment data; if yes, determining a target vehicle with a lane changing demand, and determining a longitudinal distance space required by the target vehicle to complete lane changing; and performing dynamic speed planning based on the motion state data, the map environment data and the longitudinal distance space to generate a final speed planning curve.
本申请涉及一种车辆速度规划方法及系统,该车辆速度规划方法包括:获取本车以及一个或多个相邻车辆的运动状态数据;获取地图环境数据,其中所述地图环境数据包括本车所在车道及左右相邻车道的数据;基于所述运动状态数据以及所述地图环境数据进行判定是否存在变道需求;若是,则确定存在变道需求的目标车辆,并且确定所述目标车辆完成变道所需的纵向距离空间;基于所述运动状态数据、所述地图环境数据以及所述纵向距离空间来进行动态速度规划以生成最终速度规划曲线。
