Vehicle Routing Based on Availability of Radar-Localization Objects

A system implemented in a vehicle, the system comprising:

• a radar module configured to provide radar detections of objects proximate the vehicle;
• at least one processor;
• and
• at least one computer-readable storage medium comprising instructions that, when executed by the at least one processor, implement:
• a route-selection module configured to select a route to a destination by at least:
• responsive to receiving a request to navigate to the destination, determining at least two possible routes to the destination from a current location of the vehicle;
• determining respective availabilities of radar-localization objects for the at least two possible routes;
• and
• selecting the route from the at least two possible routes based on the respective availabilities of the radar-localization objects for the at least two possible routes;
• and
• a radar-localization module configured to adjust a navigation of the vehicle by at least:
• receiving radar detections of radar-localization objects from the radar module;
• localizing the vehicle to the route based on the radar detections of the radar-localization objects;
• monitoring a radar-localization quality of the localizing;
• determining that the radar-localization quality has dropped below a threshold or that the radar-localization quality will drop below the threshold along the route;
• and
• performing at least one of:
• modifying the route;
• or
• adjusting an operation of the radar module.
