Abstract

Disclosed herein is a dialogue system capable of identifying preliminary indications related to the failure of the vehicle through a dialogue with a user, to check a part that may not be measured by a sensor and to inhibit accidents so as to provide user safety, a vehicle having the same and a dialogue processing method.

First claim

What is claimed is:

1. A dialogue system comprising:
memory;
a communication device; and
a processor configured to execute instructions stored in the memory and to:
in response to an user's utterance, extract a first search request for a check history of a vehicle from the user's utterance;
cause the communication device to transmit a second search request regarding failure cases and maintenance histories of reference vehicles, wherein a type of the reference vehicles is similar to the vehicle's type;
in response to the first search request, determine an action of the check history search based on context information including at least one of vehicle state information or driving environment information;
acquire an action parameter value of a solution to execute the action;
in response to transmitting the second search request, receive information regarding the failure cases and the maintenance histories of the reference vehicles; and
generate a response by using the acquired action parameter value and the information regarding the failure cases and the maintenance histories of the reference vehicles.

2. The dialogue system of claim 1 , wherein
the processor is further configured to determine whether to execute the action of the check history search based on the context information.

3. The dialogue system of claim 2 , wherein
the processor is configured to request a parameter value of a condition determination parameter used to determine whether to execute the action of check history search.

4. The dialogue system of claim 1 , wherein
the processor is configured to request a check history of the vehicle from a source outside of the vehicle.

5. The dialogue system of claim 4 , wherein the memory is configured to store a personal maintenance history contained in the check history, and the solution.

6. The dialogue system of claim 5 , wherein
the memory is configured to store a dialogue policy related to the solution, and
the processor is configured to recommend a service to the user based on the dialogue policy.

7. The dialogue system of claim 5 , wherein
the processor is configured to update the personal maintenance history based on the solution.

8. The dialogue system of claim 7 , wherein
the processor is configured to generate a response based on the personal maintenance history.

9. The dialogue system of claim 7 , further comprising:
a communication device configured to receive data related to the solution and configured to transmit the updated personal maintenance history to the outside.

10. The dialogue system of claim 1 , wherein
the processor is configured to generate a command for the control of the vehicle based on the solution.

11. The dialogue system of claim 1 , wherein
the processor is configured to extract a feedback according to the solution, from the user's utterance based on the response generated by the result processor.

12. The dialogue system of claim 11 , wherein
the processor is configured to determine a feedback action based on the feedback, and to acquire a feedback action parameter value to execute the feedback action.

13. The dialogue system of claim 12 , wherein
the processor is configured to generate a response by using the feedback action parameter value and to transmit the feedback to the outside.

14. The dialogue system of claim 1 , wherein
the processor is configured to determine whether it is a pre-utterance context based on the context information, wherein the pre-utterance represents a case in which the dialogue system firstly outputs an utterance before a user, and when it is determined that it is the pre-utterance context, the processor is configured to acquire at least one of an action corresponding to the request of the check history search, or a pre-utterance message including an utterance content output by the dialogue system.

15. A vehicle comprising:
memory;
a communication device; and
a processor configured to execute instructions stored in the memory and to:
in response to an user's utterance, extract a first search request for a check history of a vehicle from the user's utterance;
cause the communication device to transmit a second search request regarding failure cases and maintenance histories of reference vehicles, wherein a type of the reference vehicles is similar to the vehicle's type;
in response to the first search request, determine an action of the check history search based on context information including at least one of vehicle state information or driving environment information;
acquire an action parameter value of a solution to execute the action;
in response to transmitting the second search request, receive information regarding the failure cases and the maintenance histories of the reference vehicles; and
generate a response by using the acquired action parameter value and the information regarding the failure cases and the maintenance histories of the reference vehicles.

16. The vehicle of claim 15 , wherein
the processor is configured to determine whether to execute the action of the check history search based on the context information.

17. The vehicle of claim 16 , wherein
the processor is configured to request a parameter value of a condition determination parameter used to determine whether to execute the action of check history search.

18. The vehicle of claim 15 , wherein
the processor is configured to request a check history of the vehicle from a source outside the vehicle.

19. The vehicle of claim 18 , wherein the memory is configured to store a personal maintenance history contained in the check history, and the solution.

20. The vehicle of claim 19 , wherein
the memory is configured to store a dialogue policy related to the solution, and
the processor is configured to recommend a service to the user based on the dialogue policy.

21. A dialogue processing method comprising:
in response to an user's utterance, extracting, by a processor, a first search request for a check history of a vehicle from the user's utterance;
transmitting, by the processor, a second search request regarding failure cases and maintenance histories of reference vehicles, wherein a type of the reference vehicles is similar to the vehicle's type;
in response to the first search request, determining, by the processor, an action of the check history search based on on context information including at least one of vehicle state information or driving environment information;
acquiring, by the processor, an action parameter value of a solution to execute the action;
in response to transmitting the second search request, receiving information regarding the failure cases and the maintenance histories of the reference vehicles; and
generating, by the processor, a response according the request, by using the acquired action parameter value and the information regarding the failure cases and the maintenance histories of the reference vehicles.

22. The dialogue processing method of claim 21 , further comprising:
requesting the check history of the vehicle, to the outside.

23. The dialogue processing method of claim 22 , further comprising:
storing a personal maintenance history contained in the check history, and the solution, by memory configured to store the same.

24. The dialogue processing method of claim 23 , wherein
the storing comprises storing a dialogue policy related to the solution, and
the generation of
