However, the expansion of automobile system functions and networks, while bringing a good service experience, the increasing system complexity also brings more safety hazards. Therefore, for the safety and reliability of the vehicle, a lot of testing work needs to be done during the software development process. The traditional vehicle controller testing method often uses hardware-in-the-loop, and the controller is continuously tested and optimized through the hardware-in-the-loop simulation test platform. However, relying solely on the hardware-in-the-loop simulation test platform, the creation of test cases and the analysis of test data can only be completed by on-site testers, and it is difficult to enable more people to quickly participate in the development of automobile controllers.

Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0020] refer to Figures 1 to 4 This embodiment provides a remote vehicle control test system based on an automobile intelligent detection platform, which can not only realize remote observation and control, but also record user operation history and monitor and alarm abnormal situations. The remote vehicle control test system based on the automobile intelligent detection platform includes: a vehicle test terminal, a cloud-based intelligent detection platform and a remote client, wherein the vehicle test terminal is used to store test cases and send test requests to the in-loop test platform and receive test feedback information according to the user's setting information, and remotely monitor vehicle faults online.

[0021] In this embodiment, the vehicle test end collects vehicle information and transmits it to the cloud-based intelligent detection platform in the background. After the background collects these data, it can provide the vehicle R&D department with basic information for optimizing the vehicle, thereby improving and optimizing vehicle design and development. The vehicle test end collects detection interaction signals from various controllers and the body, chassis and human-machine system of the whole vehicle through multi-channel CAN, including detection signals of door controller, sunroof controller, engine controller, fuel controller, transmission controller, airbag controller, etc., as well as door modules. The chassis system includes tire pressure module, electronic power steering system, body stability system, etc. The human-machine system includes instrument, gateway, entertainment host, display, touch panel, etc.

[0022] Specifically, the vehicle test end includes a data forwarding module and a test case module; the data forwarding module is used to send test requests and receive test feedback information to the in-loop test platform through the OBD interface, and receive the whole vehicle control test plan transmitted by the cloud-based intelligent detection platform, and transmit test information to the cloud-based intelligent detection platform; the test case module is connected to the data forwarding module, and the test case module is used to store test cases and test information.

[0023] The in-loop test platform uses the dSPACE platform. The dSPACE real-time simulation system developed by the German dSPACE company is accurate, stable, easy to operate and powerful. The main function of the vehicle controller hardware in-loop simulation test system is to simulate the operating environment of the vehicle controller through simulation models, receive the output signal of the controller and provide the required input signal to the controller, and realize the remote control test of the car through the in-loop test platform.

[0024] In addition to in-loop testing of the vehicle, fault detection and optimization of the vehicle's actual driving status are also required. Through online vehicle fault monitoring, the vehicle's driving status parameters and fault signals can be detected in real time and transmitted to the background for analysis and reminders, thereby facilitating the optimization of vehicle performance.

[0026] In this embodiment, because different vehicles on the market use different communication protocols, data protocols need to be converted and matched when performing vehicle testing. The protocol conversion system used in this system supports vehicle communication protocols such as CAN, SAE J1850, SAEJ1939, ISO 9141, ISO 14230, PWM and VPW, covering almost all vehicle models on the market, and can easily communicate and transmit with the vehicle bus controller.

[0027] The cloud-based intelligent detection platform is used to store test instructions and test content, and to forward and store the test information of the vehicle test terminal and the data information submitted by the remote client, formulate and analyze the vehicle control strategy test plan, and also to analyze the vehicle's online faults.

When formulating and analyzing the vehicle control strategy test plan, the vehicle control strategy test plan can be adjusted according to the test requirements and conditions input by the user. The main components of the test cases in the vehicle control strategy test plan are purpose, requirement number, expected results, test results, notes, test steps, automation type, tester, test item, test version, test time, modifier, modification time, use case level, use case number, use case name, preset conditions, modification content, designer, design time, etc. When adjusting the test cases, it is completed according to the steps of analyzing functional requirements, determining the attributes of the functions, selecting test case design methods, and supplementing test cases based on experience / error deduction and other methods. Analyzing functional requirements is to break down the functional requirements into the smallest measurable units, expected inputs and clear output results. The attributes of the functions include thresholds, table lookups, conditional enablement, state jumps, fault classes, configuration classes, process classes, etc. For example, if the vehicle speed is greater than 60 and less than 120, the cruise control function can be entered. The table lookup class uses boundary values ​​and equivalence class methods, or meets condition 1 to trigger a functional failure, and recovery 1 to restore the function. The process class uses the basic path method, boundary values, scenario analysis methods, etc.

[0029] Specifically, the cloud-based intelligent detection platform includes an application management module and a database module; the application management module is used to receive the user's test commands and test content and the test results of the vehicle test end, and formulate and analyze the vehicle control strategy test plan according to the user's setting information, output the test results, and is also used to perform GIS information fusion management on the vehicle; the database module is used to store user interaction information, the user's test commands and the test results of the vehicle test end.
