[0040] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0042] Speedgoat is the HIL solution officially recommended by MathWorks. In fact, it is specially designed to be used with the simulation tool Simulink environment, and can achieve seamless connection with Matlab, Simulink Real-Time and other simulation software. For engineers who already use Simulink to develop control strategies for vehicle controllers (VCU), the learning cost is low. However, in the actual use of Speedgoat for HIL testing, there are also the following problems: Matlab comes with the real-time machine management interface Simulink Real Time Explorer, which can only manually change the parameters in the real-time machine and cannot meet the needs of automated testing.

[0043] In order to realize automatic testing, the matlab API is usually used to control the real-time machine using test cases (ie, Testcases), thereby realizing automatic testing.

[0044] See also Figure 1 , is a schematic diagram of a HIL automated test system based on Speedgoat equipment in an embodiment of the present application, wherein the host computer controls the real-time machine and the controller through matlab software and automobile calibration software INCA, and the automated test process corresponding to the above test system mainly includes the following steps:

[0045] 1. The host computer inputs test cases manually or automatically;

[0046] 2. The host computer and the real-time machine communicate using Ethernet;

[0047] 3. The host computer and the controller communicate using the XCP protocol;

[0048] 4. The host computer uses the setparam method to modify the parameters and / or calibration quantities in the real-time machine or controller according to the parameter settings in the test case, and uses the getparam method in real time to read the observed quantities after the execution parameters are modified, determine whether the controller test results meet expectations, and output the test results. Among them, getparam or setparam is a matlab parameter function.

[0049] From the above content, it can be seen that when using the matlab API method for automatic testing, in order to ensure that the host computer can modify the parameters (including parameters and calibration quantities, etc.) of the real-time machine or controller according to the test case, the test case needs to be written in the input format of the getparam or setparam function. Since the absolute path of the parameter in the Simulink model (that is, the simulation model of the virtual object under test) needs to be entered when the function is used, the function is relatively long, so the test case generation process is more cumbersome and the learning cost is high. Therefore, it is necessary to optimize the test case generation method.

[0050] In order to solve the problems of the prior art, the embodiments of the present application provide a method, apparatus, device and computer storage medium for generating hardware-in-the-loop test cases.

[0051] The following first introduces the method for generating hardware-in-the-loop test cases provided in the embodiment of the present application. The method for generating hardware-in-the-loop test cases provided in the embodiment of the present application can be applied to HIL testing of pure electric vehicles, hybrid electric vehicles or traditional fuel vehicles.

[0052] Figure 2 FIG. 1 is a flow chart showing a method for generating a hardware-in-the-loop test case according to an embodiment of the present application. Figure 2 As shown, the method for generating a hardware-in-the-loop test case provided in an embodiment of the present application may include the following steps:

[0053] S21. Obtain the original test statement.

[0054] S22. Determine a first statement and a second statement in the original test statement, wherein the first statement is a parameter operation statement, and the second statement is other statements in the original test statement except the first statement.

[0055] S23. Convert the first statement into a third statement executable by the hardware-in-the-loop test system.

[0056] S24. Combine the third statement, the second statement and the preset general operation statement to generate a test case.

[0057] The method for generating a hardware-in-the-loop test case of an embodiment of the present application obtains an original test statement, uses a parameter operation statement in the original test statement as a first statement, uses statements other than the first statement as a second statement, converts the first statement into a third statement executable by a hardware-in-the-loop test system, and combines the first statement, the third statement, and a preset general operation statement to obtain a test case executable by the hardware-in-the-loop test system. Through the above method, after obtaining the original test statement, the parameter operation statement in the original test statement can be automatically converted into a statement executable by the hardware-in-the-loop test system, without the need for engineers to manually write statements according to functions, thereby reducing the workload of engineers, improving the efficiency of test case generation, and thereby improving the efficiency of hardware-in-the-loop testing.

[0058] The specific implementation methods of the above steps are introduced below.

[0059] In some embodiments, in S21, the scripting language used by the original test statement can be a scripting language commonly used by engineers when writing scripts, for example, it can be js language, where js is javascript, a lightweight, interpreted or just-in-time compiled programming language with function priority. For example, as shown in Table 1 below, it is an example of a test case, where the content in the test statement implementation is the original test statement:

[0060] Table 1

[0061]

[0062]

[0063] In one example, when obtaining the original test statement in S11, the test statement written and input by the user (such as an engineer, etc.) according to the test requirements can be obtained as the original test statement. This method can ensure the accuracy of the test statement, and the user can write according to actual needs, which has a wider range of applications.

[0064] In one example, a test case library may be pre-set, and multiple test statements that meet different test requirements may be stored in the library. Based on this, in S11, the corresponding original test statement may be obtained from the test case library according to the test requirements. This method does not require the user to write statements, further reducing the user's workload.

[0065] Because the script language used in the original test statement does not conform to the language specification of the hardware-in-the-loop test system, the statements related to parameter operations cannot be run in the hardware-in-the-loop test system, that is, they cannot be run through MATLAB, resulting in the inability to modify the parameters in the real-time machine and / or controller, thereby making the hardware-in-the-loop test unable to proceed smoothly. Therefore, in order to ensure that the hardware-in-the-loop test can proceed smoothly, it is necessary to convert the parameter operation statements in the original test statement into a script language that can be run by the hardware-in-the-loop test system.

[0066] Based on the above reasons, after the original test statement is obtained, the original test statement can be parsed through S22 to identify the parameter variable operation statement therein, that is, the first statement.

[0067] In one example, a parameter operation statement is a statement used to operate on the parameter variables in the real-time machine and / or the controller, wherein the operations include taking values ​​and assigning values. Therefore, the parameter operation statement may include a statement for taking values ​​of the parameter variables of the real-time machine, a statement for assigning values ​​to the parameter variables of the real-time machine, a statement for taking values ​​of the parameter variables of the controller, and a statement for assigning values ​​to the parameter variables of the controller, etc.

[0068] In one example, because the parameter operation statement operates on a specific parameter in a real-time machine or controller, it usually contains an operation object identifier, which is also a real-time machine identifier and a controller identifier. Based on this, in S22, when determining the first statement in the original test statement, each statement can be identified to determine whether the statement contains an operation object identifier. If the statement contains an operation object identifier, the statement is determined to be the first statement, otherwise it is determined that the statement is not the first statement, but the second statement. In this way, the first statement and the second statement in the original test statement can be quickly identified.

[0069] After the first statement is identified, S23 may be used to convert the first statement into a script language, and convert it into a third statement executable by the hardware-in-the-loop test system, that is, a third statement that complies with the input format of the parameter function.

[0070] In one example, a test case management library can be pre-set, and multiple statement contents can be stored in the test case management library, wherein the statement content may include an operation function and a parameter absolute path, wherein 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 the specific path of the parameter in the real-time machine or controller. Based on the above content, the statement content can use the matlab m language to directly call the statement content of the parameter of the real-time machine or controller in the form of a global variable, and perform normal value acquisition and assignment operations. Based on this, in S23, when the first statement is converted into a script language, the statement content corresponding to the first statement can be obtained from the preset test case management library, and the parameter value in the first statement is determined, and finally the statement content and the parameter value are combined according to the preset statement format, thereby obtaining the third statement. Wherein, the statement format is the format of the statement that the hardware-in-the-loop test system can run, and for example, the statement format can be: operation function (parameter absolute path, parameter value).

[0071] Furthermore, because different operation functions correspond to different operation types, for example, the getparam function corresponds to a value-taking operation, the setparam function corresponds to an assignment operation, and different parameter absolute paths correspond to different operation objects and parameter variables, when obtaining the statement content corresponding to the first statement from a preset test case library, the operation information of the first statement can be determined first, the operation information including the operation object, operation type and parameter variable name, wherein the operation object is a real-time machine or controller, and the operation type is value-taking or assignment, and then the statement content corresponding to the first statement is obtained from the test case library based on the operation information.

[0072] In one example, the operation object, parameter name and parameter value of the first statement can be directly obtained from the first statement, and when determining the operation type of the first statement, the first statement can be identified to determine whether it contains a preset symbol. If it is identified that the first statement contains a preset symbol, the operation type of the first statement is determined to be assignment. If it is identified that the first statement does not contain a preset symbol, the operation type of the first statement is determined to be value acquisition. The preset symbol is a symbol that can distinguish between assignment operations and value acquisition operations, such as an equal sign, i.e., "=".

[0073] An example: the first statement is "Param1_sg=Value1". By analyzing the statement, it is determined that the operation object identifier contained therein is sg, the parameter name is Param1, and the parameter value is Value1. According to the operation object identifier, the operation object is determined to be a real-time machine. Because it contains "=", the operation type is determined to be assignment. Based on the above content, the operation function in the corresponding statement content obtained from the test case management library is setparam, and the parameter absolute path is Passenger Car / VSUM / PlantModel / Driver / Param1. The third statement obtained by combining the statement content and the parameter value is "tg.setparam('Passenger Car / VSUM / PlantModel / Driver / Param1',Value,Value1)".

[0074] In one example, in order to facilitate the acquisition of the sentence content corresponding to the first sentence, a data dictionary corresponding to the test case library can be pre-set, and then the corresponding sentence content can be acquired from the test case library based on the data dictionary. The data dictionary can store a mapping relationship between operation information and sentence content, based on which, after determining the operation information of the first sentence, the corresponding sentence content can be acquired from the test case library according to the mapping relationship in the data dictionary.

[0075] After all first statements have completed script language conversion and obtained corresponding third statements, all third statements, second statements and preset general operation statements can be combined in S24 to generate test cases.

[0076] In one example, the general operation statements can be stored in a specified location in advance, and the preset general operation statements can be directly obtained from the specified location in S24. The general operation statements are statements common to all test cases, which may include basic operation statements of the real-time machine, basic operation statements of the host computer software, and functions related to script execution.

[0077] In one example, a test case template may be pre-set, based on which, in S24, the third statement, the second statement, and the preset general operation statement may be combined according to the preset test case template to generate a test case. In this way, the combination of statements may be realized quickly, the generation efficiency of the test case is improved, and the standardization of the generated test case is ensured.

[0078] Based on the method for generating a hardware-in-the-loop test case provided in the above embodiment, the present application also provides a specific implementation of a device for generating a hardware-in-the-loop test case. Please refer to the following embodiment.

[0081] The statement parsing unit 302 is used to determine a first statement and a second statement in the original test statement, wherein the first statement is a parameter operation statement, and the second statement is other statements in the original test statement except the first statement.

[0082] The statement reconstruction unit 303 is used to convert the first statement into a third statement executable by the hardware-in-the-loop test system.

[0083] The combining unit 304 is used to combine the third statement, the second statement and the preset general operation statement to generate a test case.

[0085] As a possible implementation manner, the statement reconstruction unit 303 is used to:

[0087] Determine the value of the parameter in the first statement;

[0098] If it is identified that the first statement does not contain a preset symbol, it is determined that the operation type of the first statement is value acquisition.

[0099] As a possible implementation method, the general operation statements include basic operation statements of the real-time machine, basic operation statements of the host computer software, and functions related to script execution.
