[0001] The present invention relates to the field of intelligent networking, and in particular to a method and system for solving EOL calibration in OEM. Background Art

[0002] Currently, when performing vehicle OTA (Over-the-Air Technology), the calibration scheme is edited into the upgrade main control program through a fixed program based on the specific calibration scheme of each controller. For a single controller, each different controller requires separate development. Even if the calibration standards are flashed in IMG, TXT, and S19 formats, as long as there is a difference in data during the calibration flashing process, separate development is required.

[0003] Although the current development model can meet the calibration requirements for upgrading each controller, the following problems still exist:

[0004] (1) The calibration process, identification file method, and formula conversion of each controller are different. As a result, each time a controller is calibrated and flashed, a vehicle-side program needs to be developed, which is time-consuming and costly.

[0005] (2) Poor scalability;

[0006] (3) As a result, the vehicle-side programs become larger and more complex, and the program stability is poor;

The embodiment of the present invention also provides a system for solving EOL calibration in OEM accordingly. It should be noted that, in the present invention, OEM stands for Original Equipment Manufacturer, and EOL stands for functional testing of automotive electronic products before they come off the production line.

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0044] See also Figure 1 As shown, an embodiment of the present invention provides a method for solving EOL calibration in OEM, which specifically includes the following steps:

[0045] S1: Classify the controllers to be calibrated and flashed in the OEM, create a calibration master call library for the corresponding controllers and obtain the calibration configuration file; that is, in the early stage of development, classify and sort out the controllers to be calibrated and flashed in the OEM, and design and develop the corresponding calibration master call library.

[0046] In an embodiment of the present invention, the calibration overall call library includes the acquisition of formulas under the IMG (a file compression format) recognition mode scheme, the address sorting of flashing after recognition, and the flashing of S19 (a file format) files, as well as the acquisition of formulas under the QR (a type of two-dimensional barcode) flashing mode scheme, the address sorting of flashing after recognition, and the flashing of S19 files, as well as the acquisition of formulas under the TXT (a file format) recognition scheme, the address sorting of flashing after recognition, and the flashing of S19 files.

[0047] That is, the overall calibration call library must include how to obtain the corresponding formula from the IMG recognition mode scheme, the QR flashing mode scheme, the TXT recognition scheme, the address sorting after recognition, and the flashing of the S19 file. The calibration configuration file must be designed based on the above content.

[0048] Specifically, the calibration configuration file includes calibration standards, specific types of IMG (assigning definitions to each line in the identification file), TXT (assigning content separately for each calibration bracket) and S19. The calibration standard includes IMG, TXT and S19. The specific type of IMG includes flash mode-2E, flash mode-36 and newly added extended target logic. When it is flash mode-2E, it also includes DID, data type, whether address is filled, target address, formula, constant data judgment, data length, starting byte, sorting, whether forced and filling content. When it is flash mode-36, it also includes QR, identification method, flash quantity and target address corresponding to each QR, or also includes IMG, whether to flash and support variable quantity. TXT (assigning content separately for each calibration bracket) includes DID, whether to reuse, data type, formula, abnormal data judgment rule, data length, starting byte, sorting, whether forced, filling content and whether to read back. S19 includes identification file mode.

[0049] S2: Based on the unique identification code of the controller, the calibration configuration file is associated with the calibration processing library, the calibration flash script and the production system input data;

[0050] That is, a function needs to be developed on the server side to associate the calibration configuration file with the calibration processing library, calibration flash script and production system input data through the unique identification code of the controller.

[0051] It should be noted that, in the present invention, the classification of controllers to be calibrated and flashed, the creation of a calibration overall call library, and the association of calibration configuration files with calibration processing libraries, calibration flashing scripts and production system input data are all completed on the server side.

[0052] The controller software is universal. If you need to match different configurations of the vehicle, you need to create corresponding calibration data based on the vehicle configuration information. This is the source of input data. The production system is a system that manages the BOM data and configuration information of the actual production of the vehicle.

[0053] S3: Request the calibration file of the controller to be calibrated and flashed from the production system, and send the corresponding calibration production file to the calibration processing library to obtain the calibration file required to be flashed on the vehicle side;

[0054] The calibration processing library is a code processing library that processes all classifications. It can convert the data information configured for each classification into the actual calibration data information for the corresponding controller.

[0055] In the embodiment of the present invention, the calibration file of the controller to be calibrated and flashed is requested from the production system, and the corresponding calibration production file is sent to the calibration processing library to obtain the calibration file required to be flashed on the vehicle side. The specific steps include:

[0056] S301: Associating an INI (a file format) file and a calibration processing library with the controller to be calibrated and flashed;

[0057] S302: The server side requests the calibration file of the controller to be calibrated and flashed under the corresponding status date from the production system in units of VIN (Vehicle Identification Number);

[0058] S303: The server sends the calibration production file corresponding to the requested calibration file to the calibration processing library to obtain the calibration file required to be flashed by the vehicle.

[0059] S304: The server sends the obtained calibration file to the vehicle.

[0060] That is, after the controller is associated with the INI file and the calibration processing library, when a calibration upgrade is required, the server side requests the calibration file of the controller under the corresponding status date from the production system in units of VIN. The server side passes the corresponding calibration production file to the calibration processing library, and finally obtains the calibration file required to be flashed by the vehicle side, and then sends it to the vehicle side.

[0061] S4: The vehicle side identifies the obtained calibration file and calls the calibration flashing script to complete the flashing of the calibration file.

[0062] In the embodiment of the present invention, the vehicle side identifies the obtained calibration file and calls the calibration flashing script to complete the flashing of the calibration file. The specific steps include:

[0063] S401: The vehicle side identifies the address / DID of the obtained calibration file and the corresponding target data; the target data is the actual data information to be flashed corresponding to each DID.

[0064] S402: The vehicle side calls the calibration flashing script to complete the flashing of the calibration file.
