Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular, to a method and apparatus for updating variable attributes, a vehicle, and a storage medium. Background Art

[0002] In a vehicle electronic control system, when building application layer software, a simulation model needs to be built. As the control system becomes increasingly complex, the number of control variables in the simulation model (for example, Simulink) is also increasing. However, most simulation models only support creating control variables under a limited number of types of packages. For example, the Simulink model only supports creating control variables under 7 types of packages, and these 7 types of package types are Simulink, SimulinkBuiltin (a type package of a data format), mpt (a type package of a data format), AUTOSAR (Automotive Open System Architecture, that is, a type package of an automotive open system architecture type), AUTOSAR4 (another type package of an automotive open system architecture type), ECodeDemos (a type package of a data format), and canlib (a type package of a data format).

[0003] In the related art, for a complex electronic control system, the control variable library contains a large number of control variables. When only wanting to change the package type of variables such as Signal (signal line information) and Parameter (parameter information) without changing other attributes of the variables (for example, storage type, etc.), since most simulation models do not support direct modification, it is necessary to record the attributes of each variable and recreate each variable. During the creation process, it is necessary to input the variable attributes and reselect the package type, which greatly increases the operation difficulty.

[0004] In view of the above problems, no effective solution has been proposed yet. Summary of the Invention

[0033] The present invention will be described in detail below in conjunction with each embodiment.

[0034] Embodiment 1

[0035] According to an embodiment of the present invention, there is provided an embodiment of a method for updating variable attributes. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0036] Figure 1 FIG. is a flowchart of an optional method for updating variable attributes according to an embodiment of the present invention. As Figure 1 shown, the method includes the following steps:

[0037] Step S102, based on the first variable library, extract the variable information of the target control variable whose variable type is the preset variable type. Among them, the first variable library includes multiple control variables and the variable attributes of each control variable. The variable information at least includes: variable identifier, variable attribute, and the variable attribute includes: type package attribute and other variable attributes.

[0038] Step S104, according to the variable identifier, determine the target attribute value of the type package attribute of the target control variable. [[ID=1...]]

[0039] Step S106, update the attribute value of the type package attribute of the target control variable to the target attribute value to complete the update of the variable attributes of the target control variable.

[0040] Through the above steps, based on the first variable library, the variable information of the target control variable whose variable type is the preset variable type can be extracted. According to the variable identifier, the target attribute value of the type package attribute of the target control variable can be determined, and the attribute value of the type package attribute of the target control variable can be updated to the target attribute value to complete the update of the variable attributes of the target control variable. In the embodiment of the present invention, the variable information of the target control variable can be automatically extracted. By determining the target attribute value of the type package attribute of the target control variable and updating the attribute value of the type package attribute of the target control variable to the corresponding target attribute value, the function of batch-changing the type package attributes of the control variables can be realized, reducing the process of manually and repeatedly creating control variables, improving work efficiency, and thus solving the technical problem in the related art that when updating the variable attributes of the control variables, each control variable needs to be re-created, resulting in low work efficiency.

[0041] The embodiments of the present invention will be described in detail below in combination with the above steps.

[0042] In an embodiment of the present invention, optionally, before extracting variable information of a target control variable whose variable type is a preset variable type based on a first variable library, it further includes: determining a variable type of a plurality of control variables whose variable attributes involve a type package attribute; and using the variable type as the preset variable type, where the preset variable type at least includes: a signal line type and a parameter type.

[0043] In an embodiment of the present invention, it is possible to first determine a variable type of a control variable whose variable attribute involves a package attribute (i.e., a type package attribute), and set the variable type as the preset variable type (the preset variable type includes: a signal line type (Signal), a parameter type (Parameter), etc.), that is, first determine a target control variable involving a package type selection.

[0044] Step S102, based on the first variable library, extract variable information of a target control variable whose variable type is a preset variable type, where the first variable library includes a plurality of control variables and variable attributes of each control variable, and the variable information at least includes: a variable identifier and a variable attribute, and the variable attribute includes: a type package attribute and other variable attributes. Optionally, the other variable attributes include at least one of the following: an initial value attribute, a variable type attribute, a dimension attribute, a complex type attribute, a maximum value attribute, a minimum value attribute, a unit attribute, and a storage type attribute.

[0045] In an embodiment of the present invention, the first variable library includes a plurality of control variables and variable attributes of each control variable, which is an existing control variable library. By loading the first variable library (i.e., adding all control variables (all control variables in the first variable library) corresponding to the control system application software to the simulation software into the work area), extract variable information of a target control variable whose variable type is a preset variable type in the work area (the variable information includes: a variable identifier (i.e., a variable name), a variable attribute, etc.), and the variable attribute includes: a type package attribute and other variable attributes. In this embodiment, the other variable attributes include but are not limited to: an initial value attribute, a variable type attribute, a dimension attribute, a complex type attribute, a maximum value attribute, a minimum value attribute, a unit attribute, a storage type attribute, etc.

[0046] Optionally, the step of extracting variable information of a target control variable whose variable type is a preset variable type based on the first variable library includes: based on the first variable library, obtain all control variables, and add all control variables to a preset work area; extract a target control variable whose variable type is a preset variable type from the preset work area; based on a preset policy, obtain a variable identifier of the target control variable; based on the variable identifier, obtain a variable attribute of the target control variable; and based on the variable identifier and the variable attribute, obtain variable information of the target control variable.

[0047] In an embodiment of the present invention, all control variables in the first variable library can be obtained first, and all control variables are added to a preset work area. Then, target control variables with a preset variable type are extracted from the preset work area (that is, the control variables related to the package type selection can be extracted from the preset work area through a preset algorithm). Through a preset strategy, the variable identifier of the target control variable is obtained (for example, the variable name of the target control variable can be obtained through the code objName = var(n).name). After the variable identifier extraction is completed, through programming techniques, the variable attributes corresponding to all target control variables in the preset work area can be obtained (including: initial value, variable type, dimension, complex type, maximum value, minimum value, unit, storage type, etc.). For example, in this embodiment, the following code can be used to obtain variable attributes:

[0048] The code for extracting the initial value attribute is:

[0049] objNameInitialValue = eval([[var(n).name],'.InitialValue']);

[0050] The code for extracting the variable type attribute is:

[0051] objNameDataType = eval([[var(n).name],'.DataType']);

[0052] The code for extracting the dimension attribute is:

[0053] objNameDimensions = eval([[var(n).name],'.Dimensions']);

[0054] The code for extracting the complex type attribute is:

[0055] objNameComplexity = eval([[var(n).name],'.Complexity']);

[0056] The code for extracting the maximum value attribute is:

[0057] objNameMax = eval([[var(n).name],'.Max']);

[0058] The code for extracting the minimum value attribute is:

[0059] objNameMin = eval([[var(n).name],'.Min']);

[0060] The code for extracting the unit attribute is: objNameUnit = eval([[var(n).name],'.Unit']);

[0061] The code for extracting the storage type attribute is:

[0062] objNameStorageClass = eval([[var(n).name],'.StorageClass']).

[0063] Then, based on the variable identifier and variable attributes, the variable information of the target control variable can be obtained.

[0064] Optionally, before determining the target attribute value of the type package attribute of the target control variable based on the variable identifier, it further includes: obtaining the requirement information of the target control variable, where the requirement information includes at least one of the following: storage area information, header file information, declaration information; creating a preset type package attribute based on the requirement information; storing the attribute information of the preset type package attribute in a preset folder, where the attribute information includes at least: the target attribute value; storing the preset folder in a preset simulation project folder.

[0065] In the embodiment of the present invention, a custom package type (which can be denoted as mypackage (i.e., the preset type package)) can be created according to the actual requirements for the storage area, header file, declaration, etc. of the control variable (that is, a preset type package attribute can be created based on the obtained requirement information of the target control variable, and the requirement information includes: storage area information, header file information, declaration information, etc.). After that, the detailed information (i.e., the attribute information) of the preset type package attribute can be placed in a preset folder (for example, it can be placed in a folder named "mypackage"), and the preset folder can be placed in a preset simulation project folder (such as, the Simulink project folder).

[0066] Step S104, determine the target attribute value of the type package attribute of the target control variable according to the variable identifier.

[0067] In the embodiment of the present invention, the target attribute value of the type package attribute of the control variable can be determined according to the variable identifier of the control variable, that is, the corresponding preset type package attribute can be queried under the preset folder in the preset simulation project folder through the variable identifier to determine its target attribute value.

[0068] Another option is to store the variable identifier of the extracted target control variable and its corresponding variable attributes in a preset workspace, and add the variable identifier and variable attributes to a preset file (such as an excel table) to further update and maintain the variable information of the target control variable using the preset file.

[0069] Step S106: Update the attribute value of the type package attribute of the target control variable to the target attribute value to complete the update of the variable attribute of the target control variable.

[0070] In the embodiment of the present invention, after determining the target attribute value of the preset type package attribute of each target control variable, the attribute value of the type package attribute of the target control variable can be updated to the corresponding target attribute value to complete the update of the variable attribute of the target control variable. Moreover, in this embodiment, the attribute values of other attributes of the target control variable remain unchanged.

[0071] Alternatively, the step of updating the attribute value of the type package attribute of the target control variable to the target attribute value includes: importing the variable identifier in the preset file into the preset work area; when the variable type of the target control variable indicated by the variable identifier is the signal line type, adopting a first update strategy to update the attribute value of the type package attribute of the target control variable indicated by the variable identifier in the preset work area to the target attribute value of the preset type package attribute corresponding to the target control variable; when the variable type of the target control variable indicated by the variable identifier is the parameter type, adopting a second update strategy to update the attribute value of the type package attribute of the target control variable indicated by the variable identifier in the preset work area to the target attribute value of the preset type package attribute corresponding to the target control variable.

[0072] In an embodiment of the present invention, after managing control variables of types such as Signal (i.e., signal line type) and Parameter (i.e., parameter type) in a preset file, the control variables can be added to a preset workspace, the package type can be changed, and the variable attributes in the preset file can be inherited. Specifically, the following steps are included: (1) Import the variable names of Signal and Parameter types in the preset file; (2) Through a preset programming technique, define the package type of each variable name as "mypackage". When it is of Signal type, adopt a first update strategy (e.g., use the code: objName = mypackage.Signal) to update the attribute value of the type package attribute of this control variable to the corresponding target attribute value; when it is of Parameter type, adopt a second update strategy (e.g., use the code: objName = mypackage.Parameter) to update the attribute value of the type package attribute of this control variable to the corresponding target attribute value; (3) Through a preset programming technique, add other attributes of each control variable of Signal and Parameter types, including initial value, variable type, dimension, complex type, maximum value, minimum value, unit, storage type, etc. In this way, the package types of control variables of types such as Signal and Parameter in the preset workspace have been changed to "mypackage", and other attribute values remain unchanged.

[0073] Optionally, after updating the attribute value of the type package attribute of the target control variable to the target attribute value, it further includes: Based on a preset inheritance strategy, add the attribute values of other variable attributes to the other variable attributes of the target control variable whose type package attribute has been updated.

[0074] In an embodiment of the present invention, a preset inheritance strategy can be adopted to add the attribute values of other variable attributes to the other variable attributes of the target control variable whose type package attribute has been updated, so that only the type package attribute of the target control variable can be updated while keeping other attribute values unchanged.

[0075] Optionally, after adding the attribute values of other variable attributes to the other variable attributes of the target control variable whose type package attribute has been updated, it further includes: Store all current control variables in the preset workspace in a second variable library; Based on the second variable library, obtain the variable identifiers of all current control variables to obtain a variable identifier set; Based on the variable identifier set, determine the target control variables corresponding to each variable identifier in the first variable library to obtain a target control variable set; Replace the attribute value of the type package attribute of each target control variable in the target control variable set with the attribute value of the type package attribute of the control variable in the second variable library corresponding to the target control variable.

[0076] In an embodiment of the present invention, all current control variables in a preset work area can be stored in a second variable library, and the package types of the control variables (i.e., the target control variable set) under types such as Signal and Parameter in the original first variable library are replaced. Specifically: Based on the second variable library, the variable identifiers of all current control variables can be obtained to get a variable identifier set. Then, according to the variable identifier set, the target control variables corresponding to each variable identifier in the variable identifier set in the first variable library are determined to obtain a target control variable set. Then, the attribute value of the type package attribute of each target control variable in the target control variable set is replaced with the attribute value of the type package attribute of the control variable in the second variable library corresponding to the target control variable, so as to complete the function of batch-changing the package types of control variables.

[0077] The following is a detailed description in combination with another optional specific implementation manner.

[0078] Figure 2 It is a flowchart of an optional method for batch-changing the package type of a control variable according to an embodiment of the present invention. This embodiment is described by taking a Simulink model as an example. As Figure 2 shown, it includes the following steps:

[0079] Step S201: Create a custom package type (which can be denoted as mypackage) according to the actual requirements for the storage area, header file, declaration, etc. of the control variable (i.e., establish a custom package type according to the requirements of the control variable), and place the detailed information under this type in a folder named "mypackage", and place the "mypackage" folder in the Simulink project folder.

[0080] Step S202: Load the existing first variable library, that is, add all control variables in the control system application software corresponding to the simulation software to the work area.

[0081] Step S203: In the control system, the control variables involved in package type selection include types such as Signal (signal line information) and Parameter (parameter information). Through programming techniques, obtain the variable names of types such as Signal and Parameter, specifically including the following two steps:

[0082] (1) Find the variables under types such as Signal and Parameter in the work area;

[0083] (2) Extract their names, and the name extraction code is: objName = var(n).name.

[0084] Step S204: After completing the extraction of variable names, use programming techniques to obtain the variable attributes corresponding to all variables of types such as Signal and Parameter in the workspace, including: initial value, variable type, dimension, complex type, maximum value, minimum value, unit, storage type, etc.

[0085] Step S205: After extracting the variable names and their corresponding variable attributes of variables of types such as Signal and Parameter and storing them in the workspace, add the variable names and variable attributes to the excel to complete the update and maintenance of the control variable information.

[0086] Step S206: After completing the management of variables of types such as Signal and Parameter in the excel, add the variables to the workspace, change the package type, and inherit the variable attributes in the excel sheet. The specific steps are as follows:

[0087] (1) Import the variable names of types such as Signal and Parameter in the excel;

[0088] (2) Use programming techniques to define the package type under each variable name as "mypackage". When it is of type Parameter, the code is: objName = mypackage.Parameter; when it is of type Signal, the code is: objName = mypackage.Signal;

[0089] (3) Use programming techniques to add the attributes of each control variable of types such as Signal and Parameter, including initial value, variable type, dimension, complex type, maximum value, minimum value, unit, storage type, etc.

[0090] Step S207: After the package type of the control variables of types such as Signal and Parameter in the workspace has been changed to "mypackage" and other attribute values remain unchanged, store all the variables in the workspace at this time as the second variable library.

[0091] Step S208: Load the first variable library and the second variable library. After that, replace the package type of the control variables of types such as Signal and Parameter in the first variable library with the mypackage type of the control variables of types such as Signal and Parameter in the second variable to complete the function of batch-changing the package type of the control variables.

[0092] In the embodiments of the present invention, the process of automatically extracting the variable name and variable attributes of control variables can be realized, and the variable information of the extracted control variables is stored in a preset file for information adjustment and management. On the basis of inheriting the original variable attributes, the package type of the control variables is batch modified to a custom type, so as to reduce the process of manually and repeatedly creating control variables, save time and improve work efficiency.
