Green wave speed optimization for electric vehicle at multi-signalized intersections
摘要
Abstract
In order to improve the driving range of electric vehicles and realize energy-saving and efficient traffic,a road gradient model and a signal light model are established based on road information,and the green wave speed interval is derived for multi-signal intersections,focusing on the energy-optimal,time-optimal,and energy-time-optimal driving objectives,and the green wave speed trajectories under different driving purposes are optimized based on dynamic planning algorithms.The results show that when energy consumption is optimal,the average speed of the optimized trajectory is relatively low,and the speed fluctuates at the lower limit of the green wave speed in some sections due to the influence of gradient.When time is optimal,the vehicle adjusts to the upper limit of the green wave speed with the maximum or minimum acceleration to keep the constant driving speed,and when energy consumption is time-optimal,with the reduction of the weight of the energy consumption,the overall speed of the optimizd trajectory is increased,and the fluctuation range of the vehicle speed is reduced.关键词
