Abstract

A method for vehicular communications and information reporting. First and second wireless Internet connections between respective first and second vehicles and a web-server are provided. First and second event information is transmitted, to the web-server, from the first and second vehicles. The first and second event information relates to the same event in visual range, respectively, of occupants of the first and second vehicles. The web server may transmit, to the first and second vehicles, confirmed event information derived from the first and second event information.

Claims

1. A method of transmitting map update information, the method comprising:

receiving, by a network server, a plurality of event notifications from a plurality of first devices, the plurality of event notifications corresponding to a plurality of visual observations of a first event;

determining a minimum threshold score required for reporting the first event to one or more second devices;

processing the received plurality of visual observations to determine whether the minimum threshold score for the first event has been met;

creating a map update associated with the first event in response to the determining that the minimum threshold score has been met; and

transmitting, by the network server, the map update to the one or more second devices.

2. The method of claim 1, wherein the plurality of event notifications comprise a plurality of first geographic locations of the respective plurality of first devices at the time the plurality of event notifications were composed.

3. The method of claim 2, wherein the receiving the plurality of event notifications includes processing the plurality of first geographic locations to determine an estimated second geographic location of the first event.

4. The method of claim 3, wherein the minimum threshold score required for reporting the first event is based, at least in part, on the estimated second geographic location of the first event.

5. The method of claim 1, wherein at least one of the plurality of event notifications includes event type information and event importance information.

6. The method of claim 1, further comprising:

updating a reliability level associated with at least one of the plurality of first devices based at least in part on the processed plurality of visual observations; and

weighting subsequent communications from the at least one of the plurality of first devices based on the updated reliability level when determining whether a second minimum threshold score has been met.

7. The method of claim 1, wherein the minimum threshold score represents a minimum number of received event notifications for the first event.

8. The method of claim 1, wherein the transmitted map update modifies output of the one or more second devices.

9. The method of claim 8, wherein the map update modifies a default map database stored on each of the one or more second devices.

10. The method of claim 1, wherein the plurality of event notifications are selected from the group consisting of points of interest, vehicular incidents, vehicular accidents, objects in the road and disposition of official vehicles.

11. A system configured for transmitting map update information, the system comprising:

a network server configured for;

receiving a plurality of event notifications from a plurality of first devices, the plurality of event notifications relating to a plurality of visual observations of a first event; and

transmitting a map update to one or more second devices;

a determination module configured for determining a minimum threshold score required for reporting the first event to the one or more second devices; and

a processor configured for;

processing the received plurality of visual observations to determine whether the minimum threshold score for the first event has been met; and

creating the map update for the first event in response to determining that the minimum threshold score has been met.

12. The system of claim 11, wherein the plurality of event notifications comprise position information of the respective plurality of first devices at the time the plurality of event notifications were composed.

13. The system of claim 12, further comprising:

a location module for determining an estimated geographic location associated with the first event based on the position information of the respective plurality of first devices.

14. The system of claim 13, wherein the minimum threshold score required for reporting the first event is based, at least in part, on the estimated geographic location associated with the first event.

15. The system of claim 11, further comprising:

a subscription server configured for enabling the plurality of first devices and the one or more second devices to communicate with the network server.

16. The system of claim 11, wherein at least one of the plurality of event notifications includes event type information and event importance information.

17. The system of claim 11, further comprising:

a reliability database configured for updating a reliability level associated with at least one of the plurality of first devices based at least in part on the processed the received plurality of visual observations; and

the processor further configured for weighting subsequent communications from the at least one of the plurality of first devices based on the updated reliability level when determining whether a second minimum threshold score has been met.

18. The system of claim 11, wherein the minimum threshold score represents a minimum number of received event notifications for the first event.

19. The method of claim 11, wherein the map update modifies a default map database stored on each of the one or more second devices.

20. The method of claim 11, wherein the plurality of event notifications are selected from the group consisting of points of interest, vehicular incidents, vehicle accidents, objects in the road and disposition of official vehicles.

21. A method for transmitting map updates, the method comprising:

receiving, by a network server, a first communication from a first device, the first communication comprising first information associated with a first visual observation;

receiving, by a network server, a second communication from a second device, the second communication comprising second information associated with a second visual observation;

determining whether the first visual observation and the second visual observation correspond to a common first event based on first position information associated with the first visual observation and second position information associated with the second visual observation;

estimating a geographic position associated with the first event based on the first position information and the second position information;

generating a map update associated with the common first event based, at least in part on, the first information, the second information and the geographic position; and

transmitting, by the network server, the map update to one or more third devices.

22. The method of claim 21, wherein the geographic position is estimated with respect to the time the first communication and the second communication were composed.

23. The method of claim 21, wherein the determining is based on third information corresponding to a second event received prior to the first communication, the second event being unrelated to the first event.

24. The method of claim 23, wherein the determining is further based on comparing the first visual observation, the second visual observation and the third information.

25. The method of claim 21, further comprising:

providing a subscription service to enable the first device, the second device and the one or more third devices to communicate with the network server.

26. The method of claim 21, wherein at least the first communication further comprises event type and event importance information.

27. The method of claim 21, further comprising:

creating a reliability profile for an entity identifier associated with the first device;

updating the reliability profile based, at least in part, on determining that the first visual observation is associated with the second visual observation; and

weighting subsequent communications received from the first device based on the reliability profile.

28. The method of claim 21, wherein the map update modifies a default map database stored on each of the one or more third devices.
