Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0022] The vehicle calibration parameter conversion method provided in this application can be applied to a vehicle calibration parameter conversion system. For example... Figure 1 As shown, the vehicle calibration parameter conversion system includes a host computer 101 and a terminal 120. The host computer 101 is connected to the terminal 120.
[0023] The host computer 101 is used to calibrate the key parameters of the vehicle, export a text file containing the calibration parameters to be converted, and send the text file to be converted to the terminal 102.
[0024] Terminal 120 is used to acquire a text file containing calibration parameters of key vehicle parameters sent by host computer 101. It identifies the first line of the text file and determines its version. Based on the version, it determines the target automated conversion program for the calibration parameters. It iterates through the text file, using multiple regular expressions to determine the main variable names, variable types, data structures, and calibration parameter values. Based on the target automated conversion program, the main variable names, variable types, data structures, and calibration parameter values, it determines the programming file for converting the calibration parameters into programming language data.
[0025] The following will describe in detail, with reference to specific implementation methods, a method for converting vehicle calibration parameters provided in this application. Figure 2 A flowchart illustrating a method for converting vehicle calibration parameters provided in this application embodiment is shown below. Figure 2 As shown, the specific steps are as follows: Step 201: Obtain the text file containing the calibration parameters of the key vehicle parameters sent by the host computer.
[0026] In implementation, the host computer software exports PAR or TXT text files containing calibration parameters. These calibration parameters need to be converted into programming language initialization code, which affects the vehicle's functional debugging and system adaptation due to the configuration of the vehicle's calibration parameters. The PAR or TXT text files exported by the host computer software contain mixed data structures (scalar / multidimensional arrays), and traditional text processing tools cannot automatically recognize the dimensional information. Data types such as INT(8) / INT(16) / INT(32) also need to be manually converted to standard embedded C language type declarations such as int8 / int16 / int32. The multidimensional array initialization code must strictly follow the {A,B,C} nested format, which is prone to syntax errors such as mismatched brackets. In the existing technology, the conversion is done by manually calibrating the parameters, manually converting thousands of calibration parameters in PAR or TXT text files one by one into C variable initialization code, which takes several hours and has an error rate as high as 5%-10%. Therefore, this application develops an automated conversion method for vehicle calibration data to C language initialization code through a text recognition system. Before proceeding, it is necessary to obtain the calibration parameters of the key vehicle parameters sent by the host computer, which are to be converted into a text file. This text file can be either a PAR or TXT file; there are no restrictions.
[0027] Furthermore, before performing step 201, it is necessary to calibrate the key parameters of the vehicle through the host computer and export a text file containing the calibration parameters to be converted.
[0028] During implementation, engineers use calibration host computer software to calibrate key vehicle parameters in a real vehicle environment. After calibration, they export text files such as PAR or TXT containing all calibration parameters.
[0029] Step 202: Identify the first line of the text file to be converted, and determine the file version of the text file to be converted based on the first line.
[0030] In practice, because different versions of the text files to be converted differ in their content storage format or form, it is necessary to determine the file version of the text file after obtaining it. This can be done by identifying the first line of the text file and determining its file version based on that content.
[0031] Step 203: Determine the target automated conversion program for the calibration parameters based on the document version.
[0032] In implementation, different versions of the text files to be converted differ in their content storage format or form. Therefore, differentiated processing is required when converting calibration parameters. That is, different file versions correspond to different automated conversion programs. Thus, the target automated conversion program for calibration parameters can be determined based on the file version. This allows for precise conversion of calibration parameters into the corresponding programming language based on the file version of the text file to be converted. For example, if the file version includes low and high versions, the automated conversion program can use either keyword mapping or array expansion algorithms. When using keyword mapping, for low-version PAR files, the MEASUREMENT keyword of the calibration parameter is mapped to the volatile const type in C; while for high-version PAR files, the DEPOSIT keyword of the calibration parameter is mapped to const or volatile type, achieving more precise memory allocation. When using array expansion algorithms, for low-version PAR files, the initialization array is generated in 'row-major' order; while for high-version PAR files, it is generated in 'column-major' order, ensuring that the format of the calibration array in the C file is strictly consistent with that in the PAR file. By scanning the first line of text files such as PAR or TXT, the version of the text file is determined, and differentiated processing is achieved based on the file version.
[0033] Step 204: Traverse the text file to be converted, and use multiple regular expressions to determine the main variable name, variable type, data structure, and calibration parameter value of the calibration parameters.
[0034] In implementation, converting a text file to a programming language file involves using multiple regular expressions to extract the main variable names, variable types, data structures, and calibration parameter values. Subsequent steps can identify and detect scalars and multidimensional arrays, accurately capture calibration parameter values, and finally automatically declare variables and populate calibration values. This solves the problem of existing technologies requiring manual conversion, improving conversion efficiency and eliminating the possibility of human error. Therefore, each line of the text file to be converted can be traversed, using multiple regular expressions to determine the main variable names, variable types, data structures, and calibration parameter values.
[0035] Specifically, multiple regular expressions, including a first regular expression, a second regular expression, and a third regular expression, are used in the execution steps. The process of determining the main variable name, variable type, data structure, and value of the calibration parameters using multiple regular expressions is as follows: Step 1: Use the first regular expression to extract the main variable name and variable type of the calibration parameters.
[0036] In implementation, the first regular expression can be used to extract the main variable names and variable types of the calibration parameters. The first regular expression is: For example, using the first regular expression. For content of the form g_SoftVer [INT(8)], extract the main variable name such as: SoftVer, and extract the variable type definition such as: INT(8).
[0037] Step two: Use a second regular expression to identify the data structure of the calibration parameters.
[0038] In implementation, a second regular expression can be used to identify the data structure of the calibration parameters. This data structure includes scalars and multidimensional arrays. The second regular expression is as follows: For example, using the second regular expression. For content of the form [INT(32)] or [INT(32),(1,13)] or [INT(32),(5,7)], identify whether it is a scalar or a multidimensional array. The above are respectively a scalar, a one-dimensional array containing 13 elements, and a two-dimensional array with 5 rows and 7 columns.
[0039] Step 3: Use the third regular expression to obtain the calibration parameter values.
[0040] In implementation, a third regular expression can be used to obtain the calibration parameter values. The third regular expression is (\d+) and (\d+). For example, using the third regular expressions (\d+) and (\d+); for data of the form 106;106 or 303;0.25:390;0.45:429;0.8, the calibration parameter values can be accurately captured, as shown above for the scalar variable value 106 and the one-dimensional array value {303, 390, 429}, respectively.
[0041] Step 205: Based on the target automated conversion program, main variable name, variable type, data structure, and calibration parameter values, determine the programming file for converting the calibration parameters into programming language data.
[0042] In implementation, after obtaining the main variable names, variable types, data structures, and calibration parameter values, variable name prefixes can be added according to user requirements to complete variable declaration. Based on the identified scalar or multidimensional arrays and the captured calibration parameter values, the calibration values of the variables are then filled in. Different versions of the text files to be converted differ in their content storage formats or forms; therefore, differential processing is required during calibration parameter conversion. Thus, the difference data between the corresponding file versions can be converted based on the target automated conversion program. In this way, the programming file for converting the calibration parameters into programming language data can be determined based on the target automated conversion program, the main variable names, variable types, data structures, and calibration parameter values.
[0043] Specifically, the process of executing step 205 is as follows: Step A: Perform differential conversion on the calibration parameters according to the target automated conversion program.
[0044] During implementation, the calibration parameters can be differentiated according to the target automated conversion program.
[0045] Step B: Declare the calibration parameters according to the main variable name and variable type.
[0046] In implementation, the calibration parameters can be declared based on the extracted main variable name and variable type. For example, if the main variable name is SoftVer and the extracted variable type is defined as INT(8), then the declaration yields int8 a_c_s32_Msg_SoftVer.
[0047] Step C: Based on the data structure and calibration parameter values, fill in the calibration values of the calibration parameters and output the programming language data programming file.
[0048] In implementation, the calibration parameters can be populated with their calibration values based on the data structure and calibration parameter values. This completes the variable declaration and calibration value population for all calibration parameters, and then the programming file containing the programming language data can be output. The programming language can be C.
[0049] For example, the original PAR file data: g_SoftVer [INT(8)] 106 ; 106 / c_RtnSpd_Tab [INT(16),(1,3)] 132 ; 132 / : 194 ; 194 / : 238 ; 238 / AstSteps [INT(32),(2,3)]256 ; 0.25 / : 512 ; 0.5 / : 768 ; 0.75 / : 1024 ; 1 / : 1536 ; 1.5 / : 2048 ; 2.
[0050] Automatically generated C code: int8 a_c_s8_Msg_SoftVer = 106; int16 a_c_s16_RtnSpd_Tab[3] = {132,194,238}; int32 a_c_s32_SysCfg_AstSteps [2][3] = {{256,512},{768,1024},{1536,2048},};
[0051] This application provides a method for converting vehicle calibration parameters. By identifying the file version of the text file containing the calibration parameters, the target automated conversion program for the calibration parameters is determined. The entire text file is traversed, and multiple regular expressions are used to determine the main variable names, variable types, data structures, and calibration parameter values. Variables are automatically declared and calibration values are filled in, generating programming language code and a programming file. This reduces manual operations that take hours to complete to within 3 seconds, significantly improving conversion efficiency. Automated processing completely eliminates the possibility of errors from manual transcription, achieving a zero error rate. Furthermore, the output code can be directly embedded into embedded projects such as AUTOSAR / Simulink, making it highly adaptable to various engineering applications.

Figure 3 As shown, firstly, a PAR / TXT file is calibrated and exported via a host computer. This PAR / TXT file is then input into a text recognition system based on rules for PAR or TXT text files. The text recognition system identifies the PAR or TXT file version and determines the target automated conversion program for the calibration parameters. The system extracts variable name data types, identifies scalar multidimensional arrays, captures calibration parameter values, declares variables to populate calibration values, and generates a C code file.
