Abstract

A system comprising: an event server including a plurality of event agents for handling events occurring in a geographic space; a selector operable to select an event agent among the plurality of event agents for handling an event candidate based on a type of a source information; and a mobile object server including a mobile object agent assigned to a moving object in the geographic space, wherein the mobile object server is operable to execute the mobile object agent to collect information of an event from the selected event agent and provide the moving object with information that assists the moving object with traveling in the geographic space.

First claim

What is claimed is:

1. A computer program product for managing mobile objects, the computer program product comprising one or more computer-readable storage devices and program instructions stored on at least one of the one or more computer-readable storage devices, the program instructions comprising:
receiving source information from a first mobile object of a plurality of mobile objects pertaining to an event candidate occurring in a geographic space, wherein the source information is based on probe data from the first mobile object;
determining an event type of the event candidate;
determining an event location type of the event candidate;
determining a detected event based on matching the event type, the event location type and the source information pertaining to the event candidate to an event rule;
determining an event agent of an event server to manage movement based on the event rule, wherein a buffer size and structure of the event agent is generated based on whether the event rule is a short time type or a long-time type;
determining a characteristic of a passenger in a second mobile object; and
assisting movement of the second mobile object based on the detected event and the characteristic of the passenger, wherein assisting movement comprises commanding an action of the second mobile object, and wherein the commanded action is selected from the group consisting of: an automatic driving command and a driving assist command.

2. The computer program product of claim 1 , wherein determining the event type comprises matching information received from the first mobile object to the event detection rules for the geographic space.

3. The computer program product of claim 1 further comprising determining the event detection rule from a plurality of event detection rules based on a type of source information.

4. The computer program product of claim 3 further comprising determining an accuracy of the event detection rule, wherein the accuracy is based on an actual occurrence of the detected event, traffic statistics relating to the detected event.

5. The computer program product of claim 4 further comprising removing the event detection rule when the accuracy is below a threshold.

6. The computer program product of claim 4 further comprising updating a threshold for the event detection rule based on an actual occurrence of the detected event.

7. The computer program product of claim 1 , wherein managing movement of the second mobile object is based on a passenger in the second mobile object.

8. The computer program product of claim 1 , wherein determining the detected event is further based on a temporal density of event candidates from the plurality of mobile vehicles.

9. The computer program product of claim 1 , wherein determining the detected event is further based on a spatial density of event candidates from the plurality of mobile vehicles.

10. The computer program product of claim 1 , wherein determining the detected event is based on determining a detected event in an adjacent geographic area.

11. A computer program product for managing mobile objects, the computer program product comprising one or more computer-readable storage devices and program instructions stored on at least one of the one or more computer-readable storage devices, the program instructions comprising:
receiving, by a first mobile object server, source information from a first mobile object of a plurality of mobile objects pertaining to an event candidate occurring in a geographic space, wherein the source information is based on probe data from the first mobile object;
receiving the source information pertaining to the event candidate;
determining an event type of the event candidate;
determining an event location type of the event candidate;
determining a detected event based on matching the event type, the event location type and the source information pertaining to the event candidate to an event rule;
selecting an event server to manage the detected event, wherein the event server is selected based on the determined event rule;
determining an event agent of the event server to manage the movement based on the event rule, wherein a buffer size and structure of the event agent is generated based on whether the event rule is a short time type or a long-time type; and
assisting movement, by a second mobile object server, of the second mobile object based on the detected event which was received as source information by the first mobile object server.

12. The computer program product of claim 11 , wherein determining the event type comprises matching information received from the first mobile object to the event detection rules for the geographic space.

13. The computer program product of claim 11 further comprising determining the event detection rule from a plurality of event detection rules based on a type of source information.

14. The computer program product of claim 13 further comprising determining an accuracy of the event detection rule, wherein the accuracy is based on an actual occurrence of the detected event, traffic statistics relating to the detected event.

15. The computer program product of claim 14 further comprising removing the event detection rule when the accuracy is below a threshold.

16. The computer program product of claim 11 , wherein the first mobile object server manages a first region of a plurality of regions, wherein the second mobile object server manages a second region of a plurality of regions, wherein the plurality of regions divide geographic space.

17. The computer program product of claim 16 , wherein the first region and the second region share a common boundary.
