Abstract

A system and a method of acquiring data of an electronic control unit are provided. The method includes receiving, by a telematics server, information regarding a version of the electronic control unit mounted within a vehicle from a telematics terminal and searching for a configuration file that corresponds to the version of the electronic control unit. The telematics server is configured to generate an acquirement event file for acquiring the data of the electronic control unit using the configuration file and transmit the acquirement event file to the telematics terminal. In response to transmitting the acquirement event file, the terminal server is configured to receive the telematics terminal the data of the electronic control unit. In addition, data communication between the telematics terminal and the electronic control unit uses a controller area network (CAN) calibration protocol (CCP).

Claims

1. A method of acquiring data of an electronic control unit, comprising:

receiving, by a telematics server, information regarding a version of the electronic control unit mounted within a vehicle from a telematics terminal;

searching for, by the telematics server, a configuration file that corresponds to the version of the electronic control unit;

generating, by the telematics server, an acquirement event file for acquiring the data of the electronic control unit using the configuration file;

transmitting, by the telematics server, the acquirement event file to the telematics terminal; and

receiving, by the telematics server, the data of the electronic control unit from the telematics terminal in response to transmitting the acquirement event file,

wherein data communication between the telematics terminal and the electronic control unit uses a controller area network (CAN) calibration protocol (CCP).

2. The method of claim 1, wherein the configuration file includes data item information, data address information, and data conversion rule information.

3. The method of claim 1, wherein the acquirement event file includes data item information, data address information, data conversion rule information, and acquirement period information about data desired to acquire.

4. The method of claim 3, wherein the acquirement event file further includes acquirement period information.

5. The method of claim 1, further comprising:

requesting, by the telematics server, a version of the electronic control unit from the telematics terminal.

6. The method of claim 1, wherein data communication between the telematics terminal and the telematics server uses a wireless network.

7. A system for acquiring data of an electronic control unit, comprising:

a telematics server configured to search for a configuration file that corresponds to a version of the electronic control unit mounted within a vehicle, and generate an acquirement event file for acquiring data of the electronic control unit using the configuration file; and

a telematics terminal configured to download the acquirement event file from the telematics server, acquire data of the electronic control unit using the acquirement event file, and transmit the data of the electronic control unit to the telematics server,

wherein data communication between the telematics terminal and the electronic control unit uses a controller area network (CAN) calibration protocol (CCP).

8. The system of claim 7, wherein the configuration file includes data item information, data address information, and data conversion rule information.

9. The system of claim 7, wherein the acquirement event file includes data item information, data address information, data conversion rule information, and acquirement period information about data desired to acquire.

10. The system of claim 9, wherein the acquirement event file further includes acquirement period information.

11. The system of claim 7, wherein:

the telematics server is configured to request a version of the electronic control unit from the telematics terminal, and

the telematics terminal is configured to determine the version of the electronic control unit, and transmit information regarding the version of the electronic control unit to the telematics server.

12. The system of claim 7, wherein data communication between the telematics terminal and the telematics server uses a wireless network.

13. The system of claim 7, wherein the telematics server includes a database server in which a configuration file that corresponds to each of a plurality of electronic control units is stored.

14. A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:

program instructions that receive information regarding a version of the electronic control unit mounted within a vehicle from a telematics terminal;

program instructions that search for a configuration file that corresponds to the version of the electronic control unit;

program instructions that generate an acquirement event file for acquiring the data of the electronic control unit using the configuration file;

program instructions that transmit the acquirement event file to the telematics terminal; and

program instructions that receive the data of the electronic control unit from the telematics terminal in response to transmitting the acquirement event file,

wherein data communication between the telematics terminal and the electronic control unit uses a controller area network (CAN) calibration protocol (CCP).

15. The non-transitory computer readable medium of claim 14, wherein the configuration file includes data item information, data address information, and data conversion rule information.

16. The non-transitory computer readable medium of claim 14, wherein the acquirement event file includes data item information, data address information, data conversion rule information, and acquirement period information about data desired to acquire.

17. The non-transitory computer readable medium of claim 16, wherein the acquirement event file further includes acquirement period information.

18. The non-transitory computer readable medium of claim 14, further comprising:

program instructions that request a version of the electronic control unit from the telematics terminal.

19. The non-transitory computer readable medium of claim 14, wherein data communication between the telematics terminal and the telematics server uses a wireless network.
