Embodiment Construction
[0083] The present invention will be further described below in conjunction with accompanying drawing.
[0084] like figure 2 As shown, the vehicle lane prediction method includes the following steps,
[0085] 1) Retrieve the lane-level map in the vehicle information, the lane-level map includes a two-dimensional map and a unique road section ID number that can distinguish the three-dimensional space level of each road on the two-dimensional map;
[0086] 2) Collect and store historical traces:
[0087] Collect a set of vehicle position and heading information data for a period of time before the current time point through satellite positioning to form a set of vehicle driving history track points;
[0088] 3) Determine the ID number of the road section where the current vehicle is located:
[0089] Project a group of vehicle driving history trajectory points in step 2) onto the two-dimensional map in the lane-level map, one vehicle driving history trajectory point corresp...
