[0024] Example 1

[0025] According to an embodiment of the present invention, an embodiment of a test method for a control system is provided. 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 a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] Figure 1 is a flow chart of a control system testing method according to an embodiment of the present invention, such as Figure 1 As shown, the method comprises the following steps:

[0027] Step S102, in response to receiving a test instruction of the control system, obtaining application layer files and logic layer files of the control system, wherein the application layer files are used to represent files for implementing interactive operations in the control system, and the logic layer files are used to represent files for implementing logical processing in the control system.

[0028] The test instructions in the above steps are used to test the vehicle control system and can trigger the execution of the control system test method.

[0029] The application layer files in the above steps are files used to represent interactive operations in the vehicle control system. They usually refer to files that describe system functions and behaviors at a high level of abstraction. They can be MATLAB model files, but are not limited to them. Application layer files usually include user interfaces, input and output processing, algorithm implementation, etc.

[0030] The logic layer file in the above steps is used to represent the file that implements the logic processing in the vehicle control system. It usually refers to the file that implements the system functions and logic at the bottom layer. It can be the bottom layer software, but it is not limited to this. The logic layer file is responsible for processing the instructions from the application layer, performing the corresponding operations and returning the results to the application layer.

[0031] In an optional embodiment, after receiving the test instruction of the control system, the software executing the test method of the control system opens the software interface and displays all the application layer files and logic layer files on the server to the user, wherein the application layer files may include but are not limited to MATLAB model files, and the logic layer files may include but are not limited to the underlying software. After the user selects the required application layer files and logic layer files, the software executing the test method of the control system will download the application layer files and logic layer files of the control system from the server to the local computer, thereby completing the acquisition of the application layer files and logic layer files of the control system.

[0032] Step S104, in response to the model update instruction for the application layer file, the initial simulation model corresponding to the application layer file is updated based on the update parameters carried in the model update instruction to obtain a simulation model, wherein the initial simulation model is constructed based on the application layer file.

[0033] The model update instruction in the above steps is an instruction for updating the initial simulation model corresponding to the application layer file, and may be an Automotive Open System Architecture Extensible Markup Language (arxml) file, but is not limited thereto.

[0034] The update parameters in the above steps are parameters carried by the model update instruction, which are used to guide the specific update steps and update methods of the initial simulation model.

[0035] The initial simulation model in the above steps is an original model built based on the application layer file, which is used to describe the behavior and function of the vehicle control system. It can be a vehicle dynamics model or a vehicle control algorithm model, but is not limited to this.

[0036] The simulation model in the above steps is the latest model obtained after updating with the guidance of the update parameters. The addition of new functions can be completed through the update. New functions can be added to the initial simulation model or the original functions of the initial simulation model can be improved, so that the updated simulation model can better meet the requirements of system performance, efficiency or safety. The parameters of the initial simulation model can also be adjusted through updating to optimize the performance of the control system or adapt to more working environments. The interface of the initial simulation model can also be modified through updating so that the updated simulation model can adapt to the requirements of other systems or components. The code optimization of the initial simulation model can also be implemented during the update process to improve the operating efficiency of the control system or reduce resource consumption. Errors in the initial simulation model can also be repaired through updating to ensure the stability and reliability of the control system. However, the purpose of updating may not be limited to this.

[0037] In an optional embodiment, the model update instruction can be an arxml file, but is not limited to this. The arxml file can be downloaded from a server by software that implements a test method for a control system. The initial simulation model can be a MATLAB model file that can implement the basic functions of the control system and is built based on an application layer file. The software extracts update parameters that can characterize the vehicle control system configuration information and interface definitions from the arxml file, and then automatically runs a script file in MATLAB that is used to execute a series of MATLAB commands based on the update parameters to update the initial simulation model and obtain a simulation model. Among them, the script file can be a file with a .m extension, but is not limited to this.

[0038] The initial simulation model corresponding to the application layer file is updated using the update parameters carried by the model update instruction, which avoids manually entering a large number of MATLAB commands for the initial simulation model and improves the model update efficiency. By updating the initial simulation model, the latest configuration information, parameter settings, and interface definitions can be synchronized to the simulation model, making the updated simulation model more in line with actual needs.

[0039] Step S106, responding to the code conversion instruction for the simulation model, performing code conversion on the simulation model to obtain target code.

[0040] The code conversion instructions in the above steps are instructions for converting the simulation model into target codes.

[0041] The target code in the above steps is a code that can be used in a vehicle electronic control unit to implement vehicle control functions and complies with the Automotive Open System Architecture (AUTOSAR) standard.

[0042] In an optional embodiment, a code conversion instruction can be generated by selecting a code generation option in the simu link interface, and the simulation model is converted into a target code by simu link based on the code conversion instruction. Wherein, simu link is an additional toolbox of MATLAB, which is used for modeling, simulating and analyzing dynamic systems, and can cooperate with MATLAB to jointly complete the modeling, simulation and code generation of the control system. The target code can be AUTOSAR code, but is not limited to this. AUTOSAR is a standard for the development of automotive electronic control unit software. The purpose of converting the simulation model into AUTOSAR code is to convert the simulation model into a software code that meets the AUTOSAR standard, so as to realize the vehicle control function in the automotive electronic control unit (ECU), and improve the reusability, portability and maintainability of the software.

[0043] Step S108, testing the control system based on the logic layer file and the target code to obtain a test result, wherein the test result is used to indicate whether the control system has passed the test.

[0044] The test results in the above steps refer to the results obtained after testing the control system, which are used to indicate whether the system has passed the test. The indicators for judging the test results can be whether the functions of the control system are operating normally, whether the performance of the control system meets the requirements, or whether there are errors in the control system, but are not limited to these. The test results can be used to describe the stability and reliability of the control system and determine whether the control system meets the design requirements.

[0045] In an optional embodiment, the logic layer file can be tested using a locally stored logic layer file test case. If the logic layer file test fails, the test result is directly determined as a control system test failure. If the logic layer file test passes, click the CompileVCU button on the simu link (the button on the simu link used to edit the model) to integrate and compile the underlying software code and AUTOSAR code, that is, the logic layer file and the target code into machine code to generate a hex file (a file in hexadecimal format). Afterwards, the hex file is tested using the test case to obtain the test result.

[0046] In an embodiment of the present invention, in response to receiving a test instruction of a control system, an application layer file and a logic layer file of the control system are obtained, wherein the application layer file is used to represent a file for implementing interactive operations in the control system, and the logic layer file is used to represent a file for implementing logic processing in the control system; in response to a model update instruction for the application layer file, an initial simulation model corresponding to the application layer file is updated based on update parameters carried by the model update instruction to obtain a simulation model, wherein the initial simulation model is constructed based on the application layer file; in response to a code conversion instruction for the simulation model, the simulation model is converted into code to obtain a target code; the control system is tested based on the logic layer file and the target code to obtain a test result, wherein the test result is used to indicate whether the control system has passed the test. It is easy to notice that the initial simulation model corresponding to the application layer file is updated through the update parameters carried by the model update instruction, avoiding the use of trivial integrated development environment commands to update the initial simulation model; the application layer files and logic layer files used for control system testing are obtained, and the versions of the application layer files and logic layer files can be replaced more conveniently during testing; the application layer files and logic layer files of the control system are obtained, and the application layer files are processed using the update parameters and code conversion instructions carried by the model update instruction to obtain the target code, and the control system is tested based on the logic layer files and the target code, completing the standardized test process of the logic layer files and application layer files, avoiding the high error rate and cumbersome operation caused by manually adding files during the test process. The purpose of improving the test efficiency of the vehicle control system is achieved, thereby solving the technical problem of low test efficiency of the vehicle control system.

[0047] Optionally, the control system is tested based on the logic layer file and the target code to obtain a test result, including: responding to a first test instruction for the control system, placing the target code in the target path where the logic layer file is located for testing, and obtaining a logic test result, wherein the first test instruction is used to test the logic function of the control system, and the logic test result is used to indicate whether the logic function of the control system is normal; when the logic test result is that the logic function is normal, responding to a second test instruction for the control system, testing the control function of the control system based on the target code and the logic layer file, and obtaining a control test result, wherein the second test instruction is used to test the control function of the control system, and the control test result is used to indicate whether the control function is normal; in response to the control test result being that the control function is normal, determining that the test result is that the control system test has passed.

[0048] The first test instruction in the above steps refers to an instruction for testing the logical function of the control system, and the first test instruction can be generated by user interaction.

[0049] The logical function of the control system in the above steps is the basic logical reasoning and decision-making function of the control system when processing data and information. When testing the logical function of the control system, the contents that can be tested include but are not limited to whether the code syntax of the control system is smooth, whether the basic logic of the control system when processing data is reasonable, and whether there are conflicts in the basic logic of the control system when processing events.

[0050] The logic test results in the above steps refer to the results obtained through the logic function test, which can indicate whether the logic function of the control system is normal.

[0051] The target path in the above steps is the path where the logic layer file is located. It is also the path of the target code that needs to be prevented when performing logic function testing. It is usually a designated folder or directory in the control system.

[0052] The second test instruction in the above steps refers to an instruction for testing the control function of the control system, and the second test instruction can be generated by user interaction.

[0053] The control function of the control system in the above steps is the function of the control system to control the vehicle to complete specific behaviors according to the specified logic. When testing the control function of the control system, the contents that can be tested include but are not limited to whether the turning instruction can be successfully received, whether the right turn signal can be successfully issued, and whether the vehicle can be controlled to successfully perform the right turn operation.

[0054] The control test results in the above steps refer to the results obtained through the control function test, which are used to indicate whether the control function is normal.

[0055] In an optional embodiment, after receiving the first test instruction of the control system, the copych option on the simu link (a button on the simu link for creating a copy) is used to create a copy of the target code, and the target path where the logic layer file is located is selected to prevent the target code from being on the target path. Then the bat file (a text file) containing the logic function test case is run to obtain the logic test result. Wherein, when writing the bat file, the text editor writes the command and parameter of the test case and saves it in bat format. Since the bat file can be executed by batch processing, the test case is executed by running the bat file, which can improve the test efficiency of the control system logic function test.

[0056] When the logic test result shows that the logic function is normal, after receiving the second test instruction of the control system, the underlying software code and the AUTOSAR code, that is, the logic layer file and the target code are integrated to obtain a hex file. The hex file is compiled to obtain an executable file. The executable file is tested using the test case of the control function to obtain the control test result.

[0057] When using the test case of the control function to test the executable file, you can determine the input data, expected output, and expected behavior when writing the test case of the control function, and then use the test framework to execute the test case to ensure that the executable file works as expected, and then check the test results to determine whether the actual output is consistent with the expected output. If consistent, it is determined that the control function is normal, and if inconsistent, it is determined that the control function is abnormal. Since the control function test is started only when the logic function is normal, when the control function is normal, it can be determined that both the logic function and the control function are normal, thereby determining that the control system test has passed.

[0058] Optionally, the control function of the control system is tested based on the target code and the logic layer file to obtain a control test result, including: integrating the application layer software and the logic layer software of the control system based on the target code and the logic layer file to obtain an integration result; and testing the control function based on the integration result to obtain a control test result.

[0059] The application layer software in the above steps is the software module in the target code responsible for user interaction and business logic processing, and the logic layer software is the software module in the logic layer file responsible for processing business logic and data transmission.

[0060] The integration result in the above steps refers to the result obtained after integrating the application layer software and the logic layer software. The integration result not only includes the content of the application layer software and the content of the logic layer software, but also includes the operation interaction and data transmission between the application layer software and the logic layer software.

[0061] In an optional embodiment, the application layer software may be the AUTOSAR code obtained by updating the MATLAB model using the arxml file, and the logic layer software may be the underlying software downloaded from the server to the local computer. The AUTOSAR code and the underlying software are integrated using the CompileVCU button on the Simul ink to obtain a hex file as the integration result.

[0062] In the process of testing the control function based on the integration results, the hex file is loaded into the simulator, and the test case is written, including the control instructions and data as input, and the expected output results. Run the test case and record the test results, check whether the output results are consistent with the expectations to determine whether there are any problems with the hex file. If there are problems with the hex file, the control test result is a test failure. If there are no problems with the hex file, the control test result is a test pass.

[0063] Optionally, the application layer software and logic layer software of the control system are integrated based on the target code and the logic layer file to obtain an integration result, including: responding to a conversion instruction for the target code, calling a preset program to convert the target code into an executable file; integrating the application layer software and the logic layer software based on the executable file and the logic layer file to obtain an integration result.

[0064] The conversion instructions in the above steps are instructions for converting the target code into an executable file.

[0065] The executable file in the above steps is a file that contains machine language codes and can be run directly, usually including instructions and data.

[0066] The preset program in the above steps is a pre-written program that can convert the target code into an executable file. It can be a compiler, an assembler, or a custom compiler, but is not limited to these.

[0067] In an optional embodiment, the preset program may be a compiler, which generates conversion instructions after clicking the CompileVCU button on the simu link, and calls an external compiler according to the conversion instructions to compile the target program to obtain an executable file. The executable file may be a binary code that can be executed on a computer, a bytecode that can be executed on a virtual machine, or a hex file that can be burned into a vehicle engine control unit (Engine Control Unit, ECU for short).

[0068] Use integration tools to combine executable files and logic layer files, verify the correctness of the interface and communication between executable files and logic layer files, and ensure that executable files and logic layer files can call and run each other. Then integrate the executable files and logic layer files, and complete the integration of application layer software and logic layer software through the integration between executable files and logic layer files to obtain the integration result.

[0069] Optionally, the application layer software and the logic layer software are integrated based on the executable files and the logic layer files to obtain an integration result, including: deleting duplicate files in the executable files and the logic layer files to obtain a deletion result; determining modified files in the executable files and the logic layer files based on integration rules, wherein the modified files are used to represent files to be modified during the integration process; and integrating the application layer software and the logic layer software based on the deletion result and the modified files to obtain an integration result.

[0070] The duplicate files in the above steps are duplicate executable files and logic layer files in the software that executes the test method of the control system. The duplication form can be that the same file has multiple copies in different paths, or the file names are different but the file contents are completely duplicated, but the duplication form is not limited to this.

[0071] The deletion result in the above steps refers to the result obtained after deleting duplicate files, that is, the remaining file set.

[0072] The integration rules in the above steps refer to the rules and processes defined during the software integration process, which are used to determine which files need to be modified to ensure that the software can work properly after integration.

[0073] The modified files in the above steps are files that need to be modified during the integration process. The modification scenario may be that due to conflicts or dependencies between different modules, executable files or logic layer files need to be modified to ensure the consistency and functional integrity of the control system, but the modification scenario is not limited to this.

[0074] In an optional embodiment, for executable files and logical layer files, duplicate files can be identified by comparing file contents, or by comparing file hash values, but the method of identifying duplicate files in executable files and logical layer files is not limited to this. After duplicate files are identified, the duplicate files are deleted to reduce redundancy and improve overall efficiency.

[0075] According to the pre-set integration rules, determine whether there is a conflict or dependency between the executable file and the logical layer file, and thus determine the modified files in the executable file and the logical layer file. Modify the modified files to eliminate conflicts, resolve errors, or improve performance. Then integrate the deleted and modified executable files and logical layer files to obtain the integration results.

[0076] Optionally, after testing the control system based on the logic layer file and the target code and obtaining the test results, the method also includes: in response to the test result that the control system test passed, outputting the integration result; in response to an upload instruction for the integration result, uploading the integration result to the target server; in response to a flash instruction for the integration result, flashing the integration result to the target vehicle.

[0077] The upload instruction in the above steps is an instruction to instruct the software for executing the test method of the control system to upload the integration result to the target server. The target server is a server for receiving the integration result.

[0078] The integration result in the above steps is an instruction for instructing the software executing the test method of the control system to flash the integration result to the target vehicle. The target vehicle is a vehicle for receiving the integration result.

[0079] In an optional embodiment, if the test result is that the control system test passes, it means that the control system corresponding to the integrated result can meet the design standard, and the integrated result can be output and put into use. When the integrated result is put into use, the integrated result can be applied to the vehicle, or the integrated result can be applied to the target server. If the software that executes the test method of the control system receives an upload instruction for the integrated result, the integrated result is uploaded to the target server.
