[0019] Figure 1 This is a flowchart of the present invention; Figure 2 This is a comparative page illustration of the present invention. Detailed Implementation
[0020] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.
[0021] See Figures 1-2 A method for automatically verifying electronic control data includes the following steps: Step 1. Construct the source file page box, the target file page box, and the comparison result display box; such as Figure 2 As shown, the list box at the top left of the interface is the source file page box, the list box at the bottom left of the interface is the target file page box, and the list box on the right is the comparison result display box. Step 2. Obtain at least one source file for the entire vehicle's functions through the source file page box, such as... Figure 2 As shown, up to 6 files can be imported simultaneously; Step 3. Obtain the corresponding electronic control data target file that needs to be calibrated through the target file page box. The number of electronic control data target files is equal to the number of vehicle function source files. Step 4. Construct source file templates, target file templates, and comparison rule bases. The source file templates and target file templates have the same structure. Step 5. Read each variable from the vehicle function source file and store it in the corresponding position of the source file template; read each variable from the electronic control data target file and store it in the corresponding position of the target file template. Step 6. For the two variables in the same position in the source file template and the target file template, compare them according to the comparison rule library, and display the comparison results in the comparison result display box. Mark the variables that are inconsistent, such as in red or by highlighting them. At the same time, mark the corresponding electrical control data target files of the inconsistent variables with inequality marks, such as with red inequality signs. The display is intuitive and convenient, so that users can know at a glance which variable in which file is abnormal. Step 7. Generate and output a comparison report to guide or analyze subsequent improvement or calibration work.
[0022] Specifically, the source files for the whole vehicle functions are DCM files in hexadecimal byte format, which contain single variables, vectors, curves, and MAPs.
[0023] The target file for electronic control data is a Hex file, which contains the variables calibrated for engine electronic control data.
[0024] The present invention also includes an A2L file for the underlying calibration of electronic control data, which is an SQLite3 database file containing various parsing algorithms for parsing variables in the Hex file and aligning them with the variables in the engine electronic control data calibration and the variables in the vehicle function source file (i.e., uniform format).
[0025] The comparison rule base includes univariate comparison rules, vector comparison rules, curve comparison rules, and MAP comparison rules. During the comparison process, each variable is compared according to the corresponding comparison rule. For example, the univariate comparison rule compares whether the numerical value is within the error range, while the curve comparison rule considers not only the error range but also the trend of change.
[0026] The source files for vehicle functions and the target files for electronic control data can be imported into the source file page box and the target file page box by dragging and dropping. The operation is simple and convenient.
[0027] In step 6, variables with discrepancies are marked in red or highlighted, and a response is added to that variable. Clicking on the response will display detailed information, including the reasons for the discrepancies and corresponding solutions. The comparison report will also include the reasons for the discrepancies and corresponding solutions.
[0028] It also includes an expert database, which sets the weight and variable level for each or each type of variable. Based on the comparison results and the expert database, scores and variable level rankings are performed. Variable level ranking is used to sort the degree of influence of inconsistent variables. Scoring and variable level ranking can better help users guide or analyze subsequent improvement or calibration work.

Variables that do not match are marked, and the target files of the electrical control data corresponding to the inconsistent variables are marked as unequal. The output module is used to generate and output a comparison report.
