摘要
为了缓解纯电动汽车用户出行焦虑,提出一种考虑交通动态性及速度时变性的路径规划方法.根据道路节点位置、海拔高度、充电桩位置等信息建立沈阳市20 km×20 km区域道路拓扑结构,基于车辆充电需求、行驶距离、行驶时间、行驶能耗、附件能耗建立纯电动汽车多目标路径函数,采用蚁群算法开展路径规划.仿真结果表明,本文提出的规划方法能够找到切合实际的目标路径.
Abstract
In order to alleviate the anxiety of battery electric vehicle users in travel,a path planning method considering traffic dynamics and time-varying speed is proposed.A 20 km×20 km regional road topology is established based on road node locations,altitude,charging pile locations,etc.A multi-objective path function for battery electric vehicles is established based on vehicle charging demand,driving distance,driving time,driving energy consumption,and accessory energy consump-tion,and an ant colony algorithm is used to carry out path planning.Simulation results show that with the proposed planning method a realistic target path.
