Abstract
The vehicle lane changing trajectory planning method includes: determining a starting point and an end point of a to-be-planned path on a grid lane changing map, which is a gridded local map reflecting a lane changing condition and takes a road boundary as a map boundary; performing weight allocation on all grids in the grid lane changing map by using a potential function; searching for optimal solutions corresponding to different weight requirements between the starting point and the end point; smoothing the optimal solutions corresponding to the different weight requirements to obtain lane changing trajectories corresponding to the different weight requirements; and selecting an optimal lane changing trajectory from the lane changing trajectories corresponding to the different weight requirements.
