Description

Technical Field

[0001] The present invention relates to the field of vehicle testing technology, and in particular to an ADAS hardware-in-the-loop automated testing method, device, equipment and storage medium. Background Art

[0002] In recent years, with the rapid development of Advanced Driver Assistance System (ADAS) technology, the demand for testing has exploded and the difficulty of testing has become increasingly greater. ADAS Hardware in the Loop (HIL) testing not only covers complex technical links such as scene simulation, sensor simulation, vehicle model, and ECU hardware fusion, but also involves the integrity and real-time synchronization requirements of multiple professional data fusions. This makes the HIL test of the ADAS system more complicated than conventional ECU testing, and requires the simultaneous simulation of millimeter-wave radar detection targets and camera capture test scenarios. How to quickly and massively conduct comprehensive coverage testing has become a problem that needs to be solved in the development and release of ADAS systems.

[0003] The existing automated testing method is to build an automated test sequence based on a third-party automated testing software architecture, which is not flexible enough and does not support certain specific testing requirements. At the same time, the existing automated test sequence is built manually, which makes it difficult to ensure the consistency and accuracy of all test sequence parameters with the expected parameters in the test case, resulting in a high error rate. Therefore, there is an urgent need for a highly accurate ADAS hardware-in-the-loop automated testing solution. Summary of the invention

[0014] In one implementation of the present invention, the construction process of the scenario construction module is: according to the test scenario described in the test case, the OpenDRIVE file consistent with the test case description in the virtual scene simulation platform is retrieved, and the corresponding SCP instruction is sent to the virtual scene simulation platform, and an OpenSCENARIO test scenario file consistent with the test case description is generated based on the OpenDRIVE file.

[0015] In one implementation of the present invention, the scenario test file is an .xml road scenario file, which is a reasonable and free combination of road attributes to build an OpenDRIVE file that meets road regulations in a virtual scenario simulation platform.

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] The present invention provides an ADAS hardware-in-the-loop automated testing method, device, equipment and storage medium, which solve the problems of cumbersome and long cycle in setting up test scenarios and test sequences in existing ADAS HIL automated testing, the problem of needing to set up massive test sequences and difficult later maintenance in existing ADASHIL automated testing, and the problem of high requirements for the stability of the version of the program to be tested in existing ADAS HIL automated testing; and the problem of high customization and poor reusability between the test sequence and the test model engineering in existing ADAS HIL automated testing. Based on hardware-in-the-loop equipment, advanced ADAS systems are automatically tested. The technical solution proposed in the present invention is described in detail below through the accompanying drawings.

[0039] Example 1

[0040] Figure 1 This is the first embodiment of the present invention, specifically providing a flow chart of an ADAS hardware-in-the-loop automated testing method. Figure 1 As shown, the method mainly includes the following steps:

[0041] Step S1: Build a test case library and select the test cases to be tested.

[0042] In this embodiment, the test case library is managed in a table form. The test case table modularizes and granularizes the test requirements according to defined rules so that the automation system can automatically identify them.

[0043] Furthermore, the test requirement module includes a power-on reset module, a static scene description module, an event board module, a monitoring and evaluation module and the like.

[0044] Furthermore, the checking of the test cases to be tested is to mark the test case numbers to be tested in the test case library, so that the automated testing system can identify and locate the test cases to be tested.

[0045] Step S2: Testing the ADAS system to be tested based on the automated test system.

[0046] In this embodiment, the automated testing system is a general automated testing system, including an identification and positioning module, a scene building module, and a control execution module. Figure 2 shown.

[0047] The identification and positioning module is used to identify and locate the desired test cases checked in the test case library, and translate the test cases described in the table text into a language recognized by the computer.

[0048] The scenario building module automatically builds and generates a test scenario file consistent with the test case description according to the test case command translated by the computer.

[0049] Furthermore, the scenario building module is an automated testing system that locates the test scenario described in the test case, retrieves the OpenDRIVE file in the virtual scenario simulation platform that is consistent with the test case description, sends corresponding SCP instructions to the virtual scenario simulation platform, and builds and generates an OpenSCENARIO test scenario file that is consistent with the test case description based on the OpenDRIVE file.

[0050] The control execution module is used to issue execution test commands, control the virtual scene simulation platform and the host computer to collaboratively execute automated tests, and generate test results.

[0051] Furthermore, the control execution module is an automated test system that assigns the event board control variable parameters in the test case table to the host computer system management software, and automatically controls the host computer platform management software to execute the test task.

[0052] Furthermore, the system has the function of completing all test operations with one click, can correctly call the OpenDRIVE files consistent with the test cases in sequence, generate OpenSCENARIO test scenario files consistent with the test cases, and control the host computer management software to perform automated testing. After the system runs in a loop to complete the automated testing of all checked test cases, it will output a complete test report.

[0053] Step S3: During the test, a scene test file is generated based on the virtual scene simulation platform.

[0054] In this embodiment, the virtual scene simulation platform generates a scene test file, which is used to provide a static road scene file required for the test and generate a dynamic test scene file.

[0055] Furthermore, the static scene file is an .xml road scene file, which is a reasonable and free combination of road attributes, and an OpenDRIVE file that meets road regulations is built in the virtual scene simulation platform.

[0056] Furthermore, the generated dynamic test scenario calls the OpenDRIVE file, adds the test entity and event board content in the OpenDRIVE file according to the SCP instruction issued by the automated test system, and generates an OpenSCENARIO test scenario file that conforms to the test case to support scenario simulation testing.

[0057] Furthermore, the test event board is used to describe the behavior of traffic participants, including the initial state of the traffic participants and the behavior changes during the traffic process.

[0058] Step S4: Control the execution of the test based on the host computer management system and monitor the test results.

[0059] In this embodiment, the host computer management system receives the test execution commands issued by the automated test system in sequence, starts executing the corresponding test steps, monitors the test step process and test results, and outputs the test results.

[0060] Furthermore, when a test model project is replaced in a virtual scene based ADAS system hardware-in-the-loop automated test system, only the system interface address name needs to be changed to run the test normally.

[0061] Embodiment 1 of the present invention specifically discloses an ADAS hardware-in-the-loop automated testing method. Through the technical solution of the present invention, a computer can automatically identify variable parameters in a test case table to ensure the consistency and accuracy of parameters in the automated test.

[0062] The technical solution of the present invention can automatically generate corresponding test scenario files, reducing the dependence of ADAS HIL automated testing on pre-built and debugged test scenarios.

[0063] The technical solution of the present invention does not require the construction of a test action library (a library of defined action labels) and a test sequence library (an execution project corresponding to each test case), thereby solving the problem of cumbersome and long-cycle test sequence construction and effectively reducing manpower and time costs.

[0064] The technical solution of the present invention only needs to maintain and update the test case table in the later stage, which solves the problem of difficulty in maintaining the test action library and the test sequence library in the later stage and greatly improves the test efficiency.

[0065] The technical solution of the present invention only requires a universal system. It does not require a one-to-one correspondence between each test case and an automated test sequence. It also does not require secondary editing and can quickly adapt to changes in test requirements. It solves the problem of high requirements on the stability of the program version to be tested in the existing ADAS HIL automated test.

[0066] The automation system of the solution of the present invention is only related to the test case and is not affected by the simulation engineering model. It can conveniently and quickly reuse different simulation test engineering models, reducing a lot of repetitive work and test preparation time, and solving the problems of high customization and poor reusability between test sequences and test model engineering in existing ADAS HIL automated testing.
