Abstract

A system and method for providing vehicle diagnostic service, in which a central server cumulatively stores diagnostic trouble codes (DTCs) of vehicles, analyzes a problem history based on the DTCs, determines whether a vehicle has a problem or not using the analyzed result, notifies a driver of problem information, and remotely controls a diagnostic period and a diagnostic time for the problemed diagnostic item to perform the intensive diagnostics so that it is possible to allow the driver to promptly manage the problem.

Claims

1. A system of providing vehicle diagnostic service, the system comprising:

a diagnostic unit which analyzes a cumulatively stored diagnostic trouble code (DTC) to analyze a problem history for each vehicle; and

a control unit which compares a DTC received from a telematics device of a vehicle with the problem history to determine whether the vehicle has a problem or not, notifies a driver of problem information when the vehicle has a problem, generates a control signal for adjusting a diagnostic period for an item having a problem, and transmits the control signal to the telematics device of the vehicle.

2. The system according to claim 1, wherein the diagnostic unit divides the DTC by diagnostic item and calculates a statistic value of a problem state for each diagnostic item.

3. The system according to claim 2, wherein the control unit checks a proximity degree relating to how close a current state of each item in the received DTC is to the statistic value and determines the current state is a problem state if the proximity degree reaches a reference value.

4. The system according to claim 1, wherein the diagnostic unit collects DTCs for the same types of items of the same kinds of vehicles respectively which subscribe to a service and analyze the problem history accordingly.

5. The system according to claim 1, wherein control unit transmits information for details of the problem and a response procedure for the problem to a predesignated user terminal.

6. The system according to claim 1, wherein the control unit controls the diagnostic period with a diagnostic time.

7. The system according to claim 6, wherein the control unit makes a diagnostic period for the item having the problem shorter and makes a diagnostic time for the item having the problem longer.

8. A method of providing vehicle diagnostic service, the method comprising:

storing cumulatively a diagnostic trouble code (DTC) of a vehicle;

analyzing a problem history for the DTC cumulatively stored;

comparing the problem history with a DTC received from a telematics device to determine whether the vehicle is has a problem or not; and

in response to determining that the vehicle has a problem, notifying a driver of the problem information and adjusting a diagnostic period for a diagnostic item having a problem.

9. The method according to claim 8, wherein the analyzing a problem history includes calculating a statistic value for a problem state according to each diagnostic item after dividing the DTC by the diagnostic item.

10. The method according to claim 9, wherein the analyzing a problem history includes collecting a DTC for the same diagnostic items of the same kind of vehicles subscribed in the service to analyze the problem history.

11. The method according to claim 10, wherein the checking whether the vehicle has a problem includes checking a proximity degree relating to how closed a current state of each diagnostic item in the received DTC is to the statistic value and determining the current state is a problem state if the proximity degree reaches a reference value.

12. The method according to claim 8, wherein the adjusting a diagnostic period includes adjusting the diagnostic period with a diagnostic time.

13. A system for providing vehicle diagnostic service to a user, the system comprising:

a diagnostic unit configured to analyze cumulatively stored codes by analyzing a problem history for each vehicle; and

a control unit configured to compare each code received from a telematics device of a vehicle with the problem history to determine whether the vehicle has a problem or not, wherein in response to the control unit determining that there is a problem with the vehicle, the control unit is further configured to notify a driver of problem information, generate a control signal for adjusting a diagnostic period for an item having a problem, and transmit the control signal to the telematics device of the vehicle.

14. The system according to claim 13, wherein the diagnostic unit divides the codes according to an item within the vehicle it is related to and calculates a value of a problem state for each item.

15. The system according to claim 14, wherein the control unit checks a proximity degree relating to how close a current state of each item in the received code is to the calculated value and determines the current state is a problem state if the proximity degree reaches a reference value.

16. The system according to claim 13, wherein the diagnostic unit collects codes for the same types of items of the same kinds of vehicles respectively which subscribe to a service and analyze the problem history accordingly.

17. The system according to claim 13, wherein control unit transmits information for details of the problem and a response procedure for the problem to a predesignated user terminal.

18. The system according to claim 17, wherein the control unit makes a diagnostic period for the item having the problem shorter and makes a diagnostic time for the item having the problem longer.
