US 2024/0255293 A1 · SYSTEMS AND METHODS FOR AUTONOMOUS ROUTE NAVIGATION

Abstract

Systems and methods for autonomous lane level navigation are disclosed. In one aspect, a control system for an autonomous vehicle includes a processor and a computer-readable memory configured to cause the processor to receive a partial high-definition (HD) map that defines a plurality of lane segments that together represent one or more lanes of a roadway, the partial HD map including at least a current lane segment. The processor is also configured to generate auxiliary global information for each of the lane segments in the partial HD map. The processor is further configured to generate a subgraph including a plurality of possible routes between the current lane segment and the destination lane segment using the partial HD map and the auxiliary global information, select one of the possible routes for navigation based on the auxiliary global information, and generate lane level navigation information based on the selected route.

Dependent claims

A control system for an autonomous vehicle, comprising:

one or more vehicle sensors arranged on the autonomous vehicle;
a processor;
and
a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to:
receive a high-definition (HD) map that defines a plurality of lane segments that together represent one or more lanes of a roadway, the plurality of lane segments connecting a current lane segment to a destination lane segment,
select a portion of the HD map as a partial HD map including the current lane segment with a size based at least in part on a range of the one or more vehicle sensors;
obtain auxiliary global information for each of the lane segments in the partial HD map,
generate a subgraph including a plurality of possible routes between the current lane segment and the destination lane segment using the partial HD map and the auxiliary global information,
select one of the possible routes for navigation based on the auxiliary global information and data received from the one or more vehicle sensors, and
generate lane level navigation information based on the selected route.

receive a high-definition (HD) map that defines a plurality of lane segments that together represent one or more lanes of a roadway, the plurality of lane segments connecting a current lane segment to a destination lane segment;
select a portion of the HD map as a partial HD map including the current lane segment with a size based at least in part on a range of one or more vehicle sensors arranged on an autonomous vehicle;
obtain auxiliary global information for each of the lane segments in the partial HD map;
generate a subgraph including a plurality of possible routes between the current lane segment and the destination lane segment using the partial HD map and the auxiliary global information;
select one of the possible routes for navigation based on the auxiliary global information and data received from the one or more vehicle sensors;
and
generate lane level navigation information based on the selected route.
