METHOD FOR GUIDING VEHICLE DRIVING, MAP GENERATION METHOD, AND RELATED SYSTEM

Document Type and Number:

WIPO Patent Application WO/2023/134364

Kind Code:

A1

Abstract:

A method for guiding vehicle driving, an intersection-based map generation method, a related system, and a storage medium. The method for guiding vehicle driving comprises: generating M lane topological curves according to obstacles and lane lines in an intersection, an entry road at the intersection, and an exit road at the intersection, wherein each lane topological curve is a curve using the tail end of an entry lane of the entry road and the starting point of an exit lane of the exit road as endpoints (201); performing rationality test on the M lane topological curves to obtain K' lane topological curves, wherein K' is not greater than M (202); and when a vehicle is located in the entry road, determining a target path from the K' lane topological curves (203). Thus, the generated complete and rational lane topological curves better conform to human driving habits, corresponding navigation guidance information can be provided for vehicles during automatic driving, and the human-like properties of tracks of and the passing efficiency of vehicles passing through intersections are effectively improved.
