Abstract
An illustrative example embodiment of a system for controlling a vehicle includes at least one sensor configured to detect at least one localization reference and at least one processor configured to determine a location of the vehicle with a first precision based on an indication from the at least one sensor while the vehicle is traveling in a first lane of a roadway. The processor is configured to determine that at least one characteristic of the first precision is below a threshold and, based on the at least one characteristic being below the threshold, maneuver the vehicle to a second lane of the roadway.
Claims20
A system for controlling a vehicle, the system comprising:
- at least one sensor configured to:
- detect at least one localization reference;
- detect a signal from at least one GNSS satellite;
- and
- detect an obstruction near or on a roadway that prevents the at least one sensor from detecting a signal from the at least one GNSS satellite while the vehicle is traveling;
- and
- at least one processor configured to:
- determine a location of the vehicle with a first precision based on the at least one localization reference while the vehicle is traveling in a first lane of the roadway;
- determine that at least one characteristic of the first precision is below a threshold;
- and
- based on the at least one characteristic being below the threshold:
- determine a position of the obstruction relative to the vehicle;
- identify, using detections from the at least one sensor and the position of the obstruction relative to the vehicle, a second lane of the roadway that includes the at least one localization reference, the second lane being another lane of the roadway and adjacent to the first lane;
- and
- based on a determination that the at least one localization reference for the second lane provides a greater amount of localization reference information than the at least one localization reference for the first lane and a determination that the signal from the at least one GNSS satellite is detectable by the at least one sensor while the vehicle is in the second lane, maneuver the vehicle to the second lane of the roadway.

A computer-implemented method comprising:

- detecting a signal from at least one GNSS satellite;
- detecting an obstruction near or on a roadway that prevents the at least one sensor from detecting a signal from the at least one GNSS satellite while the vehicle is traveling;

- determining that at least one characteristic of the first precision is below a threshold;
- and
- based on the at least one characteristic being below the threshold:
- determining a position of the obstruction relative to the vehicle;
- identifying, using detections from the at least one sensor and the position of the obstruction relative to the vehicle, a second lane of the roadway that includes the at least one localization reference, the second lane being another lane of the roadway and adjacent to the first lane;
- and
- based on a determination that the at least one localization reference for the second lane provides a greater amount of localization reference information than the at least one localization reference for the first lane and a determination that the signal from the at least one GNSS satellite is detectable by the at least one sensor while the vehicle is in the second lane, maneuvering the vehicle, using the at least one processor, to the second lane of the roadway.

A non-transitory computer-readable storage medium comprising instructions that, when executed by at least one processor of a vehicle, cause the at least one processor to:
- detect, using at least one sensor of the vehicle, at least one localization reference;

- and
- based on the at least one characteristic being below the threshold:
- determine a position of the obstruction relative to the vehicle;
- identify, using detections from the at least one sensor and the position of the obstruction relative to the vehicle, a second lane of the roadway that includes the at least one localization reference, the second lane being another lane of the roadway and adjacent to the first lane;
- and
- based on a determination that the at least one localization reference for the second lane provides a greater amount of localization reference information than the at least one localization reference for the first lane and a determination that the signal from the at least one GNSS satellite is detectable by the at least one sensor while the vehicle is in the second lane, maneuver the vehicle to the second lane of the roadway.
