Abstract

A vehicle includes: motor(s), local sensors, processor(s) configured to: generate a virtual map based on the local sensors; receive a plurality of reports from a plurality of external entities, statistically compare the plurality of reports, and identify an outlying report based on the statistical comparison; instruct the external entity responsible for the outlying report to mark future reports; ignore marked reports; generate the virtual map based on unmarked reports; reallocate virtual map processing resources based on unmarked reports.

Claims

1. A vehicle comprising:

motor(s), local sensors, processor(s) configured to;

generate a virtual map based on the local sensors and a report from an external entity;

reallocate virtual map processing resources based on the report.

2. The vehicle of claim 1, wherein the processor(s) are configured to reallocate virtual map processing resources by reducing processing resources dedicated to certain geographical areas of the virtual map, the certain geographical areas being determined based on the report.

3. The vehicle of claim 2, wherein the processor(s) are configured to control the motor(s) based on the virtual map.

4. The vehicle of claim 1, wherein the processor(s) are configured to dedicate first processing resources to generating at least a portion of the virtual map from the local sensors, and, based on receipt of the report, dedicate second processing resources to generating the at least a portion of the virtual map from the local sensors.

5. The vehicle of claim 4, wherein the first processing resources exceed the second processing resources.

6. The vehicle of claim 5, wherein the processing resources comprise a generation frequency, such that when applying the first processing resources, the processor(s) generate the at least a portion of the virtual map at a first frequency and when applying the second processing resources, the processor(s) generate the at least a portion of the virtual map at a second, lower frequency.

7. The vehicle of claim 1, wherein the report comprises coordinates of a zone and a rule of the zone.

8. The vehicle of claim 7, wherein the rule of the zone is a maximum acceleration and the processor(s) are configured to control the motors based on the maximum acceleration.

9. The vehicle of claim 7, further comprising steering, wherein the rule of the zone is forbidden steering maneuver and the processor(s) are configured to prevent the steering from executing the forbidden steering maneuver when the vehicle is detected to be in the zone.

10. The vehicle of claim 9, wherein the processor(s) are configured to:

enable the forbidden steering maneuver when the vehicle is detected to be outside of the zone.

11. The vehicle of claim 1, wherein the report comprises a marked unit and wherein the processor(s) are configured to:

detect the mark and based on the detection, ignore the unit.

12. The vehicle of claim 11, wherein the report comprises an unmarked unit and wherein the processor(s) are configured to generate the virtual map based on the unmarked unit.

13. The vehicle of claim 1, wherein the processor(s) are configured to:

receive a plurality of reports from a plurality of external entities, statistically compare the plurality of reports, and identify an outlying report based on the statistical comparison.

14. The vehicle of claim 13, wherein the processor(s) are configured to:

compare timestamps of the plurality of reports and select reports for the statistical comparison based on the comparison of the timestamps.

15. The vehicle of claim 13, wherein the processor(s) are configured to:

instruct the external entity responsible for the outlying report to mark future reports.

16. The vehicle of claim 15, wherein the processor(s) are configured to:

ignore marked reports.

17. The vehicle of claim 13, wherein the statistical comparison of the plurality of reports comprises statistical comparison of only selected portions of the plurality of reports.

18. The vehicle of claim 1, wherein the report comprises a marking frequency and the processor(s) are configured to generate the virtual map based on the marking frequency.

19. A vehicle comprising:

motor(s), local sensors, processor(s) configured to;

generate a virtual map based on the local sensors;

receive a plurality of reports from a plurality of external entities, statistically compare the plurality of reports, and identify an outlying report based on the statistical comparison;

instruct the external entity responsible for the outlying report to mark future reports;

ignore marked reports;

generate the virtual map based on unmarked reports.

20. A vehicle comprising:

motor(s), local sensors, processor(s) configured to;

generate a virtual map based on the local sensors;

receive a plurality of reports from a plurality of external entities, statistically compare the plurality of reports, and identify an outlying report based on the statistical comparison;

instruct the external entity responsible for the outlying report to mark future reports;

ignore marked reports;

generate the virtual map based on unmarked reports;

reallocate virtual map processing resources based on unmarked reports.
