Abstract

An embodiment of the invention may include a method, computer program product and computer system for managing mobile objects. The embodiment may receive an event detected in a geographic space by a mobile object of a plurality of mobile objects. The embodiment may determine a reliability of the event based on a reliability associated with the mobile object. The embodiment may store the event in a mobile object database based on the reliability of the even being above a reference reliability.

Claims

1. A method for managing mobile object, the method comprising:

receiving an event detected in a geographic space by a mobile object of a plurality of mobile objects;

determining a reliability of the event based on a reliability associated with the mobile object, wherein determining the reliability of the event includes determining the reliability of the one event based on the reliability associated with each of two or more mobile objects among the plurality of mobile objects in the mobile object database, in response to the two or more mobile objects detecting the one event; and

storing the event in a mobile object database based on the reliability of the event being above a reference reliability.

2. The method according to claim 1, further comprising:

performing a process relating to the plurality of mobile objects based on the event being stored in the mobile object database.

3. The method according to claim 2, wherein performing the process includes providing notification of existence of the one event to another mobile object among the plurality of mobile objects.

4. The method according to claim 2, wherein

performing the process includes searching for a movement route of another mobile object among the plurality of mobile objects.

5. The method according to claim 1, further comprising:

updating, in the mobile object database, the reliability associated with the mobile object that detected the event in the mobile object database based on a detection result of the one event by the mobile object.

6. The method according to claim 5, wherein

updating, in the mobile object database, the reliability associated with the mobile object that detected the event based on whether the mobile object has detected existence of a target object in the geographic space.

7. The method according to claim 6, further comprising:

issuing instructions to delete information concerning the target object from map information of the geographic space possessed by the mobile object, wherein

updating, in the mobile object database, the reliability associated with the mobile object that detected the event includes increasing the reliability of the mobile object detecting an event, in response to the mobile object detecting the existence of the target object deleted from the map information.

8. The method according to claim 5, further comprising:

creating a detection rule for detecting the one event, for the mobile object.

9. The method according to claim 8, wherein

creating the detection rule includes setting a difficulty of the detection in association with the detection rule, and

updating, in the mobile object database, the reliability associated with the mobile object that detected the event includes updating an update amount of the reliability of the mobile object detecting an event, based on the difficulty of the detection associated with the detection rule.

10. The method according to claim 9, wherein

creating the detection rule includes setting the difficulty of the detection associated with the detection rule based on statistical information of detection results of an event from at least a portion of the plurality of mobile objects.

11. The method according to claim 10, further comprising:

determining the statistical information for at least a portion of the mobile objects among the plurality of mobile objects, wherein the statistical information is selected from the group consisting of;

a type of vehicle, a model of vehicle, a year model of vehicle, and a total movement distance.

12. The method according to claim 1, wherein

receiving the event detected in the geographic space by the mobile object of the plurality of mobile objects includes changing a reception frequency of the event detected by the mobile object, according to the reliability of the mobile object detecting an event.

13. The method according to claim 1, wherein

storing the event in a mobile object database includes storing the reliability of each mobile object among the plurality of mobile objects detecting an event in the mobile object database, in association with each of one or more sensors possessed by each mobile object, and

determining the reliability of the event includes determining the reliability of the one event based on the reliability associated with a sensor that detected the one event for the mobile object in the mobile object database.

14. The method according to claim 1, wherein

determining the reliability of the event includes determining the reliability of the one event further based on at least one of a behavior state of the mobile object and an environment at a location of the mobile object.

15. A computer program product for managing mobile object, the computer program product comprising:

a computer-readable storage device and program instructions stored on computer-readable storage device, the program instructions comprising;

receiving an event detected in a geographic space by a mobile object of a plurality of mobile objects;

determining a reliability of the event based on a reliability associated with the mobile object, wherein determining the reliability of the event includes determining the reliability of the one event based on the reliability associated with each of two or more mobile objects among the plurality of mobile objects in the mobile object database, in response to the two or more mobile objects detecting the one event; and

storing the event in a mobile object database based on the reliability of the event being above a reference reliability.

16. The computer program product according to claim 15 further comprising performing a process relating to the plurality of mobile objects based on the event being stored in the mobile object database.

17. The computer program product according to claim 15 further comprising updating, in the mobile object database, the reliability associated with the mobile object that detected the event in the mobile object database based on a detection result of the one event by the mobile object.

18. A computer system for managing mobile object, the computer system comprising:

a processor, a computer-readable tangible storage device, and program instructions stored on computer-readable tangible storage device for execution by the processor, the program instructions comprising;

receiving an event detected in a geographic space by a mobile object of a plurality of mobile objects;

determining a reliability of the event based on a reliability associated with the mobile object, wherein determining the reliability of the event includes determining the reliability of the one event based on the reliability associated with each of two or more mobile objects among the plurality of mobile objects in the mobile object database, in response to the two or more mobile objects detecting the one event; and

storing the event in a mobile object database based on the reliability of the event being above a reference reliability.

19. The computer system according to claim 18, the computer program product further comprising performing a process relating to the plurality of mobile objects based on the event being stored in the mobile object database.
