Abstract

An apparatus and method of creating a Controller Area Network (CAN) data file for test are provided, in which a setting value of a travelling variable of a vehicle is received, a piece of standard CAN data for communication control between control parts of the vehicle is updated by reflecting the received setting value of the travelling variable, and associated CAN data is updated based on the updated standard CAN data. A test CAN data identical to CAN data which is created during actual driving of a vehicle without having to use expensive hardware equipment or software simulation, thereby facilitating a test process at a product development stage.

Claims

1. A method of creating a Controller Area Network (CAN) data file for test, the method comprising:

receiving a setting value of a travelling variable of a vehicle;

updating a piece of standard CAN data for communication control between control parts of the vehicle by reflecting the received setting value of the travelling variable; and

updating associated CAN data based on the updated standard CAN data.

2. The method of claim 1, further comprising:

collecting a plurality of pieces of CAN data made during actual driving; and

forming the collected CAN data into a database,

wherein the updating of the associated CAN data is performed based on information about the CAN data made during actual driving in a form of the database.

3. The method of claim 2, wherein the collecting of the CAN data comprises:

receiving a standard variation of a predetermined travelling variable; and

monitoring a variation of a travelling variable relating to associated CAN data according to a change of the predetermined travelling variable, in a unit of the standard variation, and wherein

the forming of the collected CAN data into a database comprises;

forming a variation of the associated CAN data according to the change of the travelling variable into a database.

4. The method of claim 3, wherein in the updating of the associated CAN data, a modification value of the associated CAN data is determined by use of a correlation between a variation of the standard CAN data and a variation of the associated CAN data, and the associated CAN data is updated using the determined modification value.

5. The method of claim 4, wherein the variation of the standard CAN data is the variation of the predetermined travelling variable, and the variation of the associated CAN data is the variation of the travelling variable relating to the associated CAN data.

6. The method of claim 1, further comprising transporting the CAN data file for test including the updated standard CAN data and the updated associated data to test equipment.

7. The method of claim 1, further comprising:

displaying information about an initial CAN data file on a screen;

receiving a request for updating the standard CAN data included in the CAN data file for test; and

receiving identification information of the associated CAN data which is updated with the standard CAN data update.

8. The method of claim 7, wherein the initial CAN data file information includes at least one of a frequency in use of the plurality of pieces of CAN data included in the CAN data file, information about travelling variables corresponding to the CAN data and information about a modifiable range of a travelling variable.

9. The method of claim 7, wherein the updating of the associated CAN data comprises:

recognizing the identification information of the associated CAN data;

determining whether the associated CAN data needs to be modified, by use of the identification information; and

updating the associated CAN data based on the updated standard CAN data, according to a result of the determination.

10. An apparatus for creating a Controller Area Network (CAN) data file for test, the apparatus comprising:

a vehicle communication unit configured to receive a plurality of pieces of CAN data for communication control from a control part; and

a CAN data update unit configured to update a piece of standard CAN data of the received CAN data by reflecting an input setting value of a travelling variable and updates associated CAN data based on the updated standard CAN data.

11. The apparatus of claim 10, further comprising:

a database unit configured to store the plurality of pieces of CAN database; and

an information collecting unit configured to collect CAN data, which is made during actual driving of a vehicle, through the vehicle communication unit and stores the collected CAN data in the database unit, wherein

the CAN data update unit updates the associated CAN data based on information stored in the database unit.

12. The apparatus of claim 11, wherein the information collecting unit is configured to monitor a variation of a travelling variable according to a change of a predetermined travelling variable in a unit of a standard variation of the predetermined travelling variable, and to form the variation of the travelling variable according to the change of the predetermined travelling variable into a database.

13. The apparatus of claim 12, wherein the CAN data update unit determines a modification value of the associated CAN data by use of a correlation between a variation of the standard CAN data and a variation of the associated CAN data, and updates the associated CAN data using the determined modification value.

14. The apparatus of claim 10, further comprising a file transport unit configured to transport the CAN data file for test including the updated standard CAN data and the updated associated data to test equipment.

15. The apparatus of claim 10, further comprising an information input unit configured to display information about an initial CAN data file on a screen to receive a request for updating the standard CAN data included in the CAN data file for test, and identification information of the associated CAN data which is updated with the standard CAN data update.

16. The apparatus of claim 15, wherein the initial CAN data file information includes at least one of a frequency in use of the plurality of pieces of CAN data included in the CAN data file, information about a travelling variable corresponding to each CAN data and information about a range of a modifiable travelling variable.

17. The apparatus of claim 15, wherein the CAN data update unit is configured to recognize the identification information of the associated CAN data, determine whether the associated CAN data needs to be modified, by use of the identification information, and update the associated CAN data needing to be modified.
