The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0033] The simulation evaluation method, apparatus, electronic device, and storage medium of this application are described below with reference to the accompanying drawings. Addressing the problems of low efficiency and time-consuming nature caused by manual testing mentioned in the background art, this application provides a simulation evaluation method. In this method, corresponding test cases are invoked according to the target test function of the software under test, and these cases are loaded into a simulation model. The simulation model is then used to perform simulation testing on the target test function of the software under test, and test results are generated. This enables automated testing and effectively improves testing efficiency. Therefore, it solves the problems of low efficiency and time-consuming nature caused by manual testing in related technologies.

[0034] Specifically, Figure 1 This is a flowchart illustrating a simulation evaluation method provided in an embodiment of this application.

[0035] like Figure 1 As shown, this simulation evaluation method includes the following steps:

[0036] In step S101, the target test function of the software under test is obtained.

[0037] The target testing functions include one or more of the following: perception, prediction, planning, and control functions.

[0038] It is understood that the embodiments of this application can obtain the target test functions of the software under test, so as to facilitate subsequent simulation testing of the target test functions.

[0039] In step S102, the corresponding test cases are called according to the target test function, and the test cases are loaded into the simulation model. The simulation model is then used to perform simulation testing on the target test function.

[0040] The simulation model includes one or more of the following: vehicle dynamics model, sensor model, driver model, and scene rendering model.

[0041] It is understood that, according to the embodiments of this application, the corresponding test cases can be called according to the target test function and loaded into the simulation model. The simulation model is used to perform simulation testing on the target test function so as to generate the test results of the target test function based on the test data of the simulation test process.

[0042] It should be noted that the test case library is designed based on the driver assistance function. The functions include both horizontal and vertical functions, covering warning and action functions. The test case library for smoke test and full test is constructed by analyzing the basic elements of the scenario.

[0043] In this embodiment of the application, the process of using a simulation model to perform simulation testing on the target test function further includes: setting the scene information and vehicle pose information of the simulation model; and controlling the vehicle to perform preset actions based on the target signal emitted by the software under test.

[0044] The preset actions can be actions such as turning, moving forward, or reversing, and can be adjusted according to the actual situation without specific limitations.

[0045] It is understood that the embodiments of this application can set the scene information and vehicle pose information of the simulation model, thereby rendering the scene and vehicle data of the entire simulation model, and controlling the vehicle to perform preset actions based on the target signal emitted by the software under test, so as to achieve automated testing.

[0046] Specifically, communication is established between the desktop runtime environment of the software under test and the VTD, transmitting the scene information and vehicle pose information of the VTD to the software under test, and simultaneously providing the vehicle control signals calculated by the software under test to the vehicle dynamics model of the VTD.

[0047] In step S103, test results for the target test function are generated based on the test data from the simulation test process.

[0048] It is understood that the embodiments of this application can generate test results of the target test function based on the test data of the simulation test process, thereby realizing automated testing without the need for manual or actual vehicle testing, and effectively improving testing efficiency.

[0049] In this embodiment of the application, generating test results for the target test function based on test data from the simulation test process includes: acquiring simulation test data of the simulation model in the simulation test process; and performing online evaluation on the simulation test data to obtain test results for the target test function.

[0050] It is understood that the embodiments of this application can perform online evaluation of simulation test data to obtain test results for the target test function.

[0051] It should be noted that online evaluation rules are established to determine whether the current test has ended, mainly considering dangerous situations such as collisions or veering off the road.

[0052] Specifically, the test cases to be tested are selected based on the software functions, and the test cases in the test case library are loaded one by one; the software and VTD (Virtual Test Drive) in the desktop environment are started to confirm that the functional software is running normally, the VTD is executing the preset test scenarios normally, and real-time communication is normal; during the operation of the software under test and the VTD, the running status is monitored in real time. If dangerous situations such as collisions or deviations from the road occur, or if the test case termination conditions are met, such as meeting time, mileage, speed, etc., the current test is terminated; the data of the current test is stored locally for subsequent offline evaluation; after the current test case ends, it is determined whether there are any test cases that need to be tested. If so, the test case is loaded, tested, and the results are saved until all tests are completed.

[0053] In this embodiment of the application, generating test results for the target test function based on test data from the simulation test process further includes: obtaining simulation test data of the simulation model in the simulation test process; and performing offline evaluation on the simulation test data to obtain test results for the target test function.

[0054] It is understood that the embodiments of this application obtain the test results of the target test function by performing offline evaluation on simulation test data.

[0055] It should be noted that offline evaluation rules are established for different functions and scenarios. Based on the different functions, safety evaluation indicators, comfort evaluation indicators, and compliance evaluation indicators are set, including sub-indicators such as whether a collision, sudden braking, swerving, or shaking occurs. After the online test is completed, the offline evaluation module is called to read the test result data in sequence and determine whether the test result is passed according to the evaluation rules. Then, the results are filled into the test report template.

[0056] Specifically, the test result data saved in the online test is loaded one by one; the scenario pass criteria are loaded according to the test item category, and relevant items are extracted from the data according to the indicators designed in the pass criteria; it is determined whether the data meets the scenario pass criteria and the results are stored in the test report; it is determined whether there are any data items that still need to be evaluated, and if so, the evaluation process is carried out until all data evaluation is completed; the overall pass status is statistically analyzed, the results are filled into the test report, and stored on the cloud platform.

[0057] In this embodiment of the application, after generating the test results of the target test function based on the test data of the simulation test process, the method includes: sending the test results to a preset terminal.

[0058] The preset terminal can be a computer terminal or a mobile phone terminal, without specific restrictions.

[0059] It is understood that, in this embodiment of the application, after generating test results, the results are sent to a preset terminal so that the software and test case library can be updated based on these results, and iterative updates can be completed.

[0060] According to the simulation evaluation method proposed in the embodiments of this application, the corresponding test cases are called according to the target test function of the software under test, and loaded into the simulation model. The simulation model is used to perform simulation testing on the target test function of the software under test and generate test results, which can realize automated testing and effectively improve testing efficiency.

[0061] The following will combine Figures 2 to 6 The simulation evaluation method of this application is described in detail, and the specific steps are as follows:

[0062] Step 1: Design a test case library based on the driver assistance functions. The functions include horizontal and vertical functions, covering warning and action functions. By analyzing the basic elements of the scenario composition, construct a test case library for smoke testing and full-scale testing.

[0063] Step 2: Establish offline evaluation rules for different functions and scenarios. Based on the different functions, set safety evaluation indicators, comfort evaluation indicators, and compliance evaluation indicators, including sub-indicators such as whether a collision occurred, sudden braking, erratic movement, or vibration. Simultaneously, establish online evaluation rules to determine whether the current test has ended, primarily considering dangerous situations such as collisions or veering off the road.

[0064] Step 3: Establish communication between the desktop runtime environment of the software under test and the VTD, transmit the scene information and vehicle pose information of the VTD to the software under test, and at the same time, transmit the vehicle control signals calculated by the software under test to the vehicle dynamics model of the VTD.

[0065] Deploy the Genkins service so that when developers update the software code, the updated code is automatically downloaded to the test server and integrated into the test environment.

[0066] Step 4: The automated testing module integrates the latest version of the software under test into the testing environment. At the same time, it calls different test case sets according to the functions of the software under test and loads them into the VTD in sequence. It synchronously calls the runtime environment of the software under test to execute online model testing and stores the test data in local files.

[0067] If a serious hazard such as a collision or deviation from the road occurs during the test, or if the test's termination conditions are met, such as satisfying time, distance, or speed requirements, then the test will terminate. After the test concludes, check if there are any remaining test cases to execute. If so, perform the tests; otherwise, conduct offline evaluation.

[0068] Select the test cases to be tested based on the software functions, and load the test cases from the test case library one by one; start the software and VTD in the desktop environment, and confirm that the functional software is running normally, the VTD is executing the preset test scenarios normally, and real-time communication is normal; during the operation of the software under test and the VTD, monitor the running status in real time. If dangerous situations such as collisions or deviations from the road occur, or if the test case termination conditions are met, such as time, mileage, speed, etc., the current test ends; store the current test data locally for subsequent offline evaluation; after the current test case ends, determine whether there are any test cases that need to be tested. If so, load the test case, perform the test, and save the results until all tests are completed.

[0069] Step 5: After the online test is completed, call the offline evaluation module to read the test result data in sequence and determine whether the test result is passed according to the evaluation rules. Then fill the results into the test report template.

[0070] Load the test result data saved in the online test one by one; load the scenario pass criteria according to the test item category, and extract the relevant items from the data according to the indicators designed in the pass criteria; determine whether the data meets the scenario pass criteria, and store the results in the test report; determine whether there are any data items that still need to be evaluated, and if so, load the evaluation process until all data evaluation is completed; summarize the overall pass status, fill the results in the test report, and store them on the cloud platform.

[0071] Step 6: After the test report is generated, upload the report to the cloud platform and notify the testers and developers via email. This method can quickly help developers check for software logic errors during the software development process, effectively reduce the workload of testers, and accelerate software iteration efficiency.

[0072] In summary, this application addresses the issue of inaccurate vehicle models by introducing professional vehicle dynamics software, resulting in simulation results that more closely resemble actual performance. The automated testing and evaluation modules effectively improve testing efficiency and consistency, avoiding the time developers would otherwise spend on testing and enhancing software iteration efficiency. Compared to on-road testing by personnel driving test vehicles, this method is not limited by personnel, vehicles, or time constraints. After deploying the automated testing framework, software versions can be monitored in real time, and test tasks are automatically triggered and test reports generated when software updates occur, saving manpower and resources. Each test is executed automatically and results are stored, ensuring good test consistency and facilitating problem reproduction and analysis. Furthermore, it allows for comparison of results with historical software versions, enabling the statistical analysis of the number of issues and additions / closures during software iteration.
