Speedcoat is a HIL solution recommended by the mathworks official, the Real Time is specially designed to be used together with a simulation tool Simulink environment, seamless butt joint with simulation software such as Matlab and Simulink Real-Time can be achieved, and the learning cost is low for engineers who use the Simulink to develop a Control strategy of a Vehicle Controller (VCU). However, in the actual HIL test process using Speedgoat, the following problems also exist: the matlab with the Real-Time machine management interface Simulink Real Time Explorer can only manually change parameters in the Real-Time machine, and cannot meet the requirement of automatic testing.

In order to implement automatic testing, a matlab API is usually used to control a real-time machine using a Test case (i.e., a Test case), so as to implement automatic testing.

Referring to fig. 1, a schematic diagram of an HIL automated testing system based on Speedgoat equipment in the embodiment of the present application is shown, where an upper computer controls an actual time and a controller through matlab software and vehicle calibration software INCA, and an automated testing process corresponding to the testing system mainly includes the following steps:

1. the upper computer inputs a test case in a manual or automatic mode;

2. the upper computer and the real-time machine communicate by using Ethernet;

3. the upper computer and the controller communicate by using an XCP protocol;

4. the upper computer modifies parameters and/or standard quantities in the real-time machine or the controller by using a setparam method according to parameter setting in the test case, reads the observed quantity after the parameters are modified by using the getparam method in real time, judges whether the test result of the controller meets expectation or not, and outputs the test result, wherein the getparam or the setparam is used as a matlab parameter function.

It can be known from the above contents that, when the matlab API is used for automatic testing, in order to ensure that an upper computer can modify real-time or parameter variables (including parameters, standard quantities and the like) of a controller according to a test case, the test case needs to be written in a sentence according to an input format of a getparam or setparam function, and because an absolute path of the parameter variables in a Simulink model (i.e., a simulation model of a virtual object to be tested) needs to be input during the use of the function, the function is relatively long, so that the test case generation process is troublesome, the learning cost is high, and therefore, the test case generation mode needs to be optimized.

In order to solve the prior art problems, embodiments of the present application provide a method, an apparatus, a device, and a computer storage medium for generating a hardware-in-the-loop test case.

The method for generating the hardware-in-loop test case provided by the embodiment of the application can be applied to HIL (hardware in loop) tests of pure electric vehicles, hybrid electric vehicles or traditional fuel vehicles.

Fig. 2 illustrates a flowchart of a method for generating a hardware-in-the-loop test case according to an embodiment of the present application. As shown in fig. 2, the method for generating a hardware-in-the-loop test case according to the embodiment of the present application may include the following steps:

and S21, acquiring an original test statement.

S22, determining a first statement and a second statement in the original test statement, wherein the first statement is a parameter variable operation statement, and the second statement is other statements except the first statement in the original test statement.

And S23, converting the first statement into a third statement which can be run by the hardware-in-the-loop test system.

And S24, combining the third statement, the second statement and a preset general operation statement to generate a test case.

The method for generating the hardware-in-the-loop test case includes the steps of obtaining an original test statement, taking a parameter variable operation statement in the original test statement as a first statement, taking statements except the first statement as a second statement, converting the first statement into a third statement which can be run by a hardware-in-the-loop test system, and combining the first statement, the third statement and a preset general operation statement to obtain the test case which can be run by the hardware-in-the-loop test system. By the method, after the original test statement is obtained, the parameter operation statement in the original test statement can be automatically converted into the statement which can be run by the hardware-in-loop test system, an engineer does not need to manually write the statement according to a function, the workload of the engineer is reduced, the generation efficiency of the test case is improved, and the efficiency of the hardware-in-loop test is further improved.

Specific implementations of the above steps are described below.

In some embodiments, in S21, the script language used by the original test statement may be a script language commonly used by engineers to write scripts, for example, a js language, which is javascript, a lightweight, interpreted, or just-in-time programming language with function priority. For example, as shown in table 1 below, an example of a test case is shown, where the content in the implementation of the test statement is the original test statement:

TABLE 1

In one example, when the original test statement is obtained in S11, a test statement written and input by a user (for example, an engineer or the like) according to a test requirement may be obtained as the original test statement. By adopting the method, the accuracy of the test statement can be ensured, and the user can write the test statement according to the actual requirement, so that the application range is wider.

In one example, a test case library may also be preset, and a plurality of test statements meeting different test requirements are stored in the library, based on which, in S11, corresponding original test statements may be obtained from the test case library according to the test requirements. By adopting the method, the user does not need to write the sentences, and the workload of the user is further reduced.

Because the script language used by the original test statement does not conform to the language specification of the hardware-in-the-loop test system, the statement related to parameter operation cannot run in the hardware-in-the-loop test system, that is, cannot run through matlab, so that the modification of parameter variables in a real-time machine and/or a controller cannot be realized, and the hardware-in-the-loop test cannot be smoothly carried out. Therefore, in order to ensure that the hardware-in-loop test can be smoothly performed, the parameter operation statements in the original test statements need to be subjected to script language conversion, and converted into the script language which can be run by the hardware-in-loop test system.

For the above reasons, after the original test statement is obtained, the original test statement may be analyzed through S22 to identify the parameter operation statement, that is, the first statement, therein.

In an example, the parameter operation statement is a statement for operating a parameter in a real-time machine and/or a controller, where the operation includes a value taking and an assignment, and thus the parameter operation statement may include a statement for taking a value of the parameter at the real-time, a statement for assigning a value of the parameter at the real-time, a statement for taking a value of the parameter of the controller, and a statement for assigning a value of the parameter of the controller.

In one example, since the argument operation statement is to operate on a specific argument in a real-time machine or a controller, an operation object identifier is usually included therein, and the operation object identifier is also called a real-time machine identifier and a controller identifier. Based on this, in S22, when determining the first statement in the original test statement, it may be separately identified, for each statement, whether the statement includes the operand identifier, and if the operand identifier is included, the statement is determined to be the first statement, otherwise, the statement is determined not to be the first statement, but to be the second statement. In this way, the first statement and the second statement in the original test statement can be quickly identified.

After the first statement is identified, S23 may be used to perform a script language conversion on the first statement, and convert the first statement into a third statement that the hardware can run in the ring test system, that is, a third statement that conforms to the input format of the parameter function.

In one example, a test case management library may be preset, and a plurality of statement contents may be stored in the test case management library, where the statement contents may include an operation function and a parameter absolute path, where the operation function may be a parameter function of matlab, such as a getparam function or a setparam function, and the parameter absolute path is a specific path of a parameter in a real-time or in a controller. Based on the above contents, the statement content can use matlab m language to directly call the statement content in a global variable mode on the parameter of the real time or the controller, and carry out normal value taking and assignment operation. Based on this, in S23, when performing script language conversion on the first statement, the statement content corresponding to the first statement may be acquired from the preset test case management library, the parameter value in the first statement may be determined, and finally, the statement content and the parameter value may be combined according to the preset statement format, so as to obtain the third statement. The statement format is a format of a statement that the hardware-in-the-loop test system can run, and for example, the statement format may be: operation functions (parameter absolute path, parameter values).

Further, because different operation functions correspond to different operation types, for example, a getparam function corresponds to a value operation, a setparam function corresponds to a value operation, and different parameter absolute paths correspond to different operation objects and parameters, when obtaining statement content corresponding to a first statement from a preset test case library, operation information of the first statement may be determined first, where the operation information includes an operation object, an operation type, and a parameter name, where the operation object is an actual time or a controller, the operation type is a value or a value, and then, the statement content corresponding to the first statement is obtained from the test case library based on the operation information.

In an example, an operation object, a parameter name, and a parameter value of a first statement may be directly obtained from the first statement, and when the operation type of the first statement is determined, the first statement may be identified to determine whether a preset symbol is included therein, if the preset symbol is included in the first statement, the operation type of the first statement is determined to be an assignment, and if the preset symbol is not included in the first statement, the operation type of the first statement is determined to be a value. The preset symbol is a symbol that can distinguish between an assignment operation and a value operation, and may be, for example, an equal sign, that is, "=".

An example is as follows: the first statement is ' Param1_ sg = Value 1', the statement is analyzed to determine that the operation object contained therein is sg, the parameter name Param1 and the parameter Value is Value1, the operation object is determined to be a real-time machine according to the operation object identifier, and because "=" is contained therein, the operation type is determined to be an assignment, based on the above contents, the operation function in the corresponding statement content obtained from the test case management library is setparam, and the parameter absolute path is passger Car/VSUM/plantatmodel/Driver/Param 1, so that the third statement obtained by combining the statement content and the parameter Value is ' tg.

In one example, in order to obtain the sentence content corresponding to the first sentence, a data dictionary corresponding to the test case library may be set in advance, and then the corresponding sentence content may be obtained from the test case library based on the data dictionary. The data dictionary can store the mapping relation between the operation information and the sentence content, and based on the mapping relation, after the operation information of the first sentence is determined, the corresponding sentence content can be obtained from the test case library according to the mapping relation in the data dictionary.

After all the first statements complete the script language conversion to obtain corresponding third statements, all the third statements, the second statements, and the preset general operation statements may be combined through S24 to generate a test case.

In one example, the general operation statement may be stored in advance in the designated location, and the preset general operation statement may be directly acquired from the designated location in S24. The general operation statements are statements common to all test cases, and may include basic operation statements of real time, basic operation statements of upper computer software, functions related to script running, and the like.

In one example, a test case template may be preset, and based on this, in S24, the third statement, the second statement and the preset general-purpose operation statement may be combined according to the preset test case template to generate the test case. By the method, the combination of the sentences can be quickly realized, the generation efficiency of the test cases is improved, and the normalization of the generated test cases is ensured.
