Abstract

Provided is a vehicle data providing apparatus supporting to easily generate vehicle internal communication data at the development stage of a product to perform a test. According to an aspect, there is provided a vehicle data providing apparatus including: a vehicle data analyzer configured to analyze a vehicle data file that is used in a vehicle, and to provide a reference data graph about reference data included in the vehicle data file; a vehicle data changing unit configured to receive a user input signal for changing the reference data, and to change related data associated with the reference data based on the reference data graph; and a test data file generator configured to generate a vehicle data file for test, including the changed reference data and the changed related data.

Claims

1. A vehicle data providing apparatus comprising:

a vehicle data analyzer configured to analyze a vehicle data file that is used in a vehicle, and to provide a reference data graph about reference data included in the vehicle data file;

a vehicle data changing unit configured to receive a user input signal for changing the reference data, and to change related data associated with the reference data based on the reference data graph; and

a test data file generator configured to generate a vehicle data file for test, including the changed reference data and the changed related data.

2. The vehicle data providing apparatus of claim 1, further comprising a display configured to display the reference data graph provided by the vehicle data analyzer,

wherein the vehicle data analyzer configures a screen showing the changed reference is data and the changed related data in a graph form and displays the screen through the display.

3. The vehicle data providing apparatus of claim 1, wherein the vehicle data changing unit receives a user input signal for setting a correction region on the reference data graph, and changes the related data based on a changed amount of the reference data included in the correction region.

4. The vehicle data providing apparatus of claim 3, wherein the user input signal for changing the reference data is a signal for moving a graph line included in the correction region on the reference data graph in a specific direction.

5. The vehicle data providing apparatus of claim 1, further comprising:

a vehicle communication unit configured to receive the vehicle data file by communicating with the vehicle; and

a data storage configured to store data,

wherein the vehicle data analyzer collects the vehicle data file, generates vehicle information database using the collected vehicle data file, and stores the vehicle information database in the data storage.

6. The vehicle data providing apparatus of claim 5, wherein the vehicle data analyzer monitors a changed amount of the reference data from the collected vehicle data file, monitors a changed amount of the related data according to the changed amount of the reference data, and stores the changed amount of the reference data and the changed amount of the related data according to the changed amount of the reference data to thereby generate the vehicle information database.

7. The vehicle data providing apparatus of claim 1, wherein the vehicle data analyzer predicts a changed amount of the related data corresponding to the changed amount of the reference data, and store the predicted, changed amount of the related data to thereby reflect the predicted, changed amount of the related data to vehicle information database.

8. The vehicle data providing apparatus of claim 1, further comprising a user input unit configured to receive a user input signal for setting reference data and related data associated with the reference data with respect to vehicle data included in the vehicle data file.

9. The vehicle data providing apparatus of claim 1, wherein if the user input signal indicates to change reference data that is within a correction region, the vehicle data changing unit changes the reference data and the related data associated with the reference data in response to the user input signal, whereas if the user input signal indicates to change reference data that is not within the correction region, the vehicle data changing unit ignores the user input signal.

10. The vehicle data providing apparatus of claim 1, further comprising a file transfer unit configured to transfer a vehicle data file for test to a test apparatus that performs a test using the vehicle data file for test.

11. A vehicle data providing method comprising:

analyzing a vehicle data file that is used in a vehicle, and providing a reference data graph about reference data among data included in the vehicle data file;

is receiving a user input signal for changing the reference data based on the reference data graph; and

changing the reference data and related data associated with the reference data according to reception of the user input signal; and

generating a data file for test, including the changed reference data and the changed related data.

12. The vehicle data providing method of claim 11, further comprising configuring a screen showing the changed reference data and the changed related data in a graph form and displaying the screen.

13. The vehicle data providing method of claim 11, further comprising receiving a user input signal for setting a correction region of the reference data graph,

wherein the changing of the related data according to the reception of the user input signal comprises when the user input signal for setting the correction region of the reference data graph is received, changing the related data based on a changed amount of reference data included in the correction region.

14. The vehicle data providing method of claim 11, wherein the user input signal for changing the reference data is a signal for moving a graph line included in the correction region on the reference data graph in a specific direction.

15. The vehicle data providing method of claim 11, further comprising:

collecting the vehicle data file; and

is analyzing a plurality of pieces of data packets included in the collected vehicle data file to generate vehicle information database.

16. The vehicle data providing method of claim 15, wherein the generating of the vehicle information database comprises:

monitoring a changed amount of the reference data from the collected vehicle data file;

monitoring a changed amount of the related data according to the changed amount of the reference data; and

storing the changed amount of the reference data and the changed amount of the related data according to the changed amount of the reference data.

17. The vehicle data providing method of claim 15, wherein the generating of the vehicle information database further comprises predicting a changed amount of the related data corresponding to the changed amount of the reference data, and storing the predicted, changed amount of the related data.

18. The vehicle data providing method of claim 11, further comprising receiving a user input signal for setting reference data and related data associated with the reference data with respect to vehicle data included in the vehicle data file.

19. The vehicle data providing method of claim 11, further comprising transmitting the data file for test to a test apparatus.

20. The vehicle data providing method of claim 11, wherein the generating of the data is file for test comprises:

decoding a data packet included in the vehicle data file;

reflecting, if the data packet includes at least one of the changed reference data and the changed related data, a value of the at least one of the changed reference data and the changed related data to the decoded data packet; and

encoding the resultant data packet to which the value of the at least one of the changed referenced data and the changed related data has been reflected.
