In the embodiment of the application, the key in the dictionary is the variable name of the variable in the A2L file, and the value is the variable value of the variable.

s101: and reading the variable name of the variable to be deleted.
In this step, the variable name of the variable to be deleted may be read from a variable list to be deleted, where the variable list to be deleted is stored in the device that processes the variable in the A2L file in advance, and may also be stored in other devices, such as a server device.
S102: and judging whether the read variable name is a key in the partial dictionary corresponding to the A2L file, if so, executing S103, and otherwise, ending.
In this step, the dictionary is used to store the variable names and variable values of the partial variables after the A2L file is split according to the variable types in the A2L file, the keys in the dictionary are the variable names of the variables in the A2L file, and the values are the variable values corresponding to the variable names, that is, the contents of the variables in the A2L file may be numerical values or literal descriptions. There is at least one variable in one dictionary and different types of variables exist in different dictionaries. The specific generation mode of the dictionary is as follows: according to the type of the variable, the A2L file is divided into a file header part and a plurality of non-file header parts, the file header part is stored in a character string, and the variables of the non-file header parts are stored in all dictionaries, wherein the non-file header parts comprise: calibration amount (characteristic) information, measurement amount (measurement) information, axis score (axis _ pts) information, recording layout (record _ layout) information, function (function) information, vibration (composition _ vtab) information, pattern (composition _ method) information, unit (unit) information.
Wherein, the file header part contains project information, such as project number, project version and other information; the calibration quantity information is used for defining calibration variables and comprises information such as names, addresses, lengths, calculation formulas, precisions, maximum and minimum values and the like of the variables which can be calibrated, and one ECU can have a plurality of calibration variables; the measured variable information is used for defining measured variables and comprises information such as names, addresses, lengths, calculation formulas, precision, maximum and minimum values and the like of the variables which can be measured, and one ECU can have a plurality of measured variables; the axis information is used for defining the type of the axis corresponding to an array or a table lookup variable, the axis is referred by the recorded layout information, and an ECU (electronic control unit) can have a plurality of different axis types for realizing table lookup and interpolation, and is generally rarely used; recording the physical storage structure of the layout information for defining the calibration variables, such as a single variable, a two-dimensional table, a three-dimensional table, and the like; the vibration information is used for defining the mapping relation between an original value and a physical value, is a special conversion relation and is generally applied to enumeration variables; the mode information is used for defining a calculation formula which can be referred to by a calibration variable and a measurement variable so as to convert an original value into a physical value convenient for reading and use, and a conversion relation between the original value and the physical value; the unit information generally includes information such as description of the unit, and the like; the function information is used to define the function, and usually includes the calibration quantity and the measurement quantity defined by the function, the output calibration quantity and the measurement quantity, the name of the included subfunction, the specific definition of each subfunction, the input and output calibration quantity and the measurement quantity, and so on.
Storing a plurality of variables of non-header parts into a dictionary, storing variable names and variable values of the variables in the calibration quantity information into a calibration quantity dictionary (calDict), storing the variable names and the variable values of the variables in the measurement quantity information into a measurement quantity dictionary (mesDict), storing the variable names and the variable values of the variables in the axis information into an axis dictionary (axis Dict), storing the variable names and the variable values of the variables in the function information into a function dictionary (func Dict), and the like. The contents of each dictionary store are shown in tables 1-8 below.
TABLE 1 calibration volume dictionary
TABLE 2 measurement dictionary
TABLE 3 dictionary with axes
TABLE 4 record layout dictionary
TABLE 5 function dictionary
TABLE 6 vibration dictionary
TABLE 7 schema dictionary
TABLE 8 Unit dictionary
In an alternative embodiment, some variables in the A2L file are not deleted, such as variables in the recording layout information, so that variables in the recording layout dictionary, vibration dictionary information, pattern dictionary, unit dictionary may not be considered when deleting variables.
S103: the variable names and the variable values corresponding to the variable names are deleted from the dictionaries.
In this step, for each dictionary, if the key of the dictionary is the variable name of the variable to be deleted, the variable name and the variable value corresponding to the variable name are deleted. In this case, some variables in the dictionary are not deleted, such as variables in the recording layout information, variables in the vibration information, variables in the pattern information, and variables in the unit information, so that when deleting the variables, only the variable names and variable values of the variables to be deleted in the calibration quantity dictionary, the measurement quantity dictionary, the axis division dictionary, and the function dictionary may be deleted.
It should be noted that a function may include multiple sub-functions, or there may be nested functions in the function, so that the same variable name may correspond to different variable values in different sub-functions or functions, that is, the same key in the function dictionary may have different values. Therefore, when the variable to be deleted belongs to the function information and the variable name and the variable value of the variable to be deleted in the function dictionary are deleted, the whole function dictionary of the variable is required. Specifically, the keys in the function dictionary are traversed, and if the keys in the function dictionary are variable names of variables to be deleted, the variable names and variable values corresponding to the variable names are deleted from the function dictionary. The specific deletion process is described in reference to fig. 2, and will not be further described here.

In the step, after the variable names and the variable values of all the variables to be deleted in the variable list to be deleted are deleted from each dictionary, the remaining variable names and the variable values corresponding to the remaining variable names in each dictionary are sequentially written into a new file according to the variable sequence in the A2L file before splitting, and the file header and the file end mark of the A2L file are added to generate a new A2L file.
In the embodiment of the application, the A2L file is split into multiple parts according to the type of the variable, the file header part is stored in the character string, other parts are separately stored in the dictionaries, the variable name of the variable to be deleted is read from the variable list to be deleted, the variable name and the variable value corresponding to the variable name are deleted from each dictionary, and new A2L files are generated according to the variable sequence after deletion, so that the automatic processing of the A2L files is realized, compared with manual processing, manpower and material resources are saved, and the processing efficiency and accuracy of the A2L files are improved.
