[0002] With the development of the automotive industry, the research and development cycle of new models is getting shorter and shorter. However, during the development process of new models, it is necessary to test and evaluate the vehicle's business capabilities in various scenarios.

[0003] Currently, when testing vehicles on test benches, many low-level signals from onboard devices are difficult to trigger on the test bench, making real-world scenarios difficult to verify. Developers' lack of familiarity with the applications that rely on them complicates data integration. This necessitates that test evaluations be conducted in real-world scenarios to complete functional debugging and testing before mass production. However, test scenarios can be temporally or spatially uncontrollable, such as rainy days, high / low temperatures, and congested conditions. These conditions are often subject to random factors and cannot be arbitrarily controlled, leading to delays in the R&D cycle.

DETAILED DESCRIPTION

[0059] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts, including but not limited to combinations of multiple embodiments, are within the scope of protection of this application.

[0060] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the numbers used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0061] Scenario-based services for in-vehicle systems are a key development direction for system intelligence in automotive technology. Scenarios such as commuting, traffic jams, rainy weather, and highway driving are derived from scenarios generated by the scenario engine based on real-time vehicle status, user profiles, and external business environment data. Scenarios rely on numerous data sources from various business entities, including vehicle body signals, navigation data, media information, schedules, and weather conditions. In actual development, developers often face numerous data challenges, such as difficulty triggering underlying signals on test benches, difficulties verifying and implementing real-world scenario conditions, and complex data integration and debugging due to unfamiliarity with application-dependent services. These challenges increase the workload of scenario developers and testers and hinder the integration and debugging of scenarios for subscribers. As the time between vehicle product upgrades shortens, these challenges are increasingly hindering R&D progress, reducing testing efficiency and increasing testing costs.

[0062] In general, the existing technology has technical problems in vehicle development and testing, such as uncontrollable vehicle usage scenarios, which leads to long development time and high testing costs.

[0063] In order to solve the above technical problems, the invention concept of this application is:

[0064] A vehicle usage scenario simulation testing method is proposed. The data simulation application generates simulation data based on a unified data protocol for vehicle system services by simulating the numerous business data required for scenario calculations (such as vehicle body signals, navigation data, media information, schedules, weather conditions, and voice conversations). This simulation data is sent to the test engine via a simulation service, a business program process running within the simulation test system. The test engine receives this simulation data, completes legality verification, sorts data consumption, and then inputs the data into the test engine to calculate the vehicle usage scenario and simultaneously updates the business information to the scenario message bus. The scenario message bus then updates the scenario simulation monitoring backend with data logs, scenario card interaction information, scenario calculation logs, and scenario subscription notifications in real time.

[0065] The scenario simulation backend displays simulation logs in chronological order based on the scenario message bus and automatically stores them in log files. This allows developers to easily and clearly verify scenario services and debug scenario subscription interfaces. This significantly reduces the R&D costs of scenario-based services for various in-vehicle systems. Furthermore, mode and frequency configurations can be configured to meet testers' automated testing needs.

[0066] Figure 1 This is a schematic diagram of an application scenario of a vehicle scenario simulation test method provided in this application. Figure 1 As shown, the vehicle-mounted system of the vehicle to be tested 100 is transplanted into the test engine of the simulation test system 200. The simulation test system 200 inputs simulation protocols for various vehicle usage scenarios, for example, simulation protocols for commuting scenarios, highway scenarios, rural outdoor scenarios, and special scenarios. The so-called special scenarios include tunnels, basements, toll booths, elevated roads, and other scenarios with weak signals. After simulating each vehicle usage scenario and forming vehicle usage scenario simulation data, it is input into the test engine to simulate the service trigger conditions of the vehicle-mounted system in the corresponding vehicle usage scenario, and perform business testing or stress testing on the vehicle-mounted system. The simulation test system 200 then outputs the corresponding simulation test results. Developers adjust the various business modules of the vehicle-mounted system by analyzing the test results, so that the test can be completed without the actual vehicle reaching the vehicle usage scenario.

[0067] Figure 2 This is a flow chart of a vehicle usage scenario simulation test method provided in an embodiment of the present application. Figure 2 As shown, the specific steps of the vehicle usage scenario simulation test method include:

[0068] S201: Acquire and parse simulation configuration information input by a developer.

[0069] In this step, the simulation configuration information includes: data configuration and transmission configuration information. The data configuration is used to specify one or more vehicle usage scenarios, as well as the type and coding value range of various simulation parameters for each vehicle usage scenario. The transmission configuration information includes: one or more transmission frequencies of the transmission scenario simulation data and one or more start transmission times corresponding to each transmission frequency.

[0070] Specifically, developers (including testers) enter simulation configuration information on the simulation test system's configuration interface to specify one or more vehicle usage scenarios to simulate, the order in which each scenario should be simulated, and the simulation start time. Furthermore, if developers want to stress-test the test vehicle's service processing capabilities, they can also adjust the transmission frequency of the simulation data in this step.

[0071] After the developer completes entering the simulation configuration information and clicks Submit, the simulation test system obtains the simulation configuration information and performs configuration analysis to clarify the developer's simulation requirements.

[0072] S202 : According to the parsing result of the simulation configuration information, the scenario configuration data corresponding to the simulation configuration information is loaded, and the scenario simulation data is determined according to the scenario configuration data and a preset scenario simulation protocol.

[0073] In this step, the simulation test system determines one or more vehicle usage scenarios corresponding to the scenario configuration data, as well as the type and value range of each parameter in the scenario configuration data according to the data configuration in the simulation configuration information.

[0074] Specifically, developers need to pre-build simulation protocols based on various vehicle usage scenarios. This means digitizing the vehicle usage scenarios. For example, in a rainy day scenario, the corresponding rain sensor values ​​need to be set, and the rainfall intensity needs to be simulated by varying the values. Each simulation protocol is pre-entered into the simulation test system, allowing the simulation test system to determine the required simulation protocol based on the simulation configuration information and generate the corresponding scenario simulation data.

[0075] In one possible design, if a developer configures multiple vehicle usage scenarios, the simulation configuration information also requires setting simulation modes, such as manual and automatic modes. Manual mode means that the developer manually determines when to generate scenario simulation data for each vehicle usage scenario and when to send that scenario simulation data to the test engine for testing, using the simulation test system's user interface. Automatic mode, on the other hand, means that the developer pre-sets the simulation order for each vehicle usage scenario, either in a random order, and also sets the simulation start time and duration for each scenario.

[0076] S203. Send scenario simulation data to the test engine according to the transmission configuration information in the analysis result to change the vehicle usage scenario in the test engine and test various preset services corresponding to the vehicle usage scenario.

[0077] In this step, scenario simulation data is sent to the test engine according to each transmission frequency in the transmission configuration information and one or more transmission start times corresponding to each transmission frequency.

[0078] Optionally, after receiving the scenario simulation data, the scenario engine can first perform a validity check to avoid the situation where the scenario simulation data is not discarded in time after the user temporarily changes the test target or test content, resulting in erroneous test results and misleading developers.

[0079] It should be noted that during the test process, the test engine can transmit test data to the simulation monitoring background in the form of wired or wireless communication. The simulation monitoring background generates corresponding record logs based on the test data, so that developers can conduct retrospective analysis of the test process at each moment after the test is completed. Because many times, test analysis cannot be completed at the time of testing, it is necessary to organize and summarize the test results after the test to find problems, and then trace the test process to find the real problem.

[0080] In one possible design, the test engine sends test data to the message bus during the test process. The simulation monitoring background only needs to read the data on the message bus to obtain the test data, thereby generating the corresponding record log.

[0081] This embodiment provides a vehicle usage scenario simulation test system method, which obtains and parses the simulation configuration information input by the developer; according to the parsing result of the simulation configuration information, loads the scenario configuration data corresponding to the simulation configuration information, and determines the scenario simulation data according to the scenario configuration data and the preset scenario simulation protocol; according to the transmission configuration information in the parsing result, sends the scenario simulation data to the test engine to change the vehicle usage scenario in the test engine, and tests the various preset services corresponding to the vehicle usage scenario. It solves the technical problem in the prior art that the vehicle usage scenario is uncontrollable during vehicle research and development testing, resulting in long research and development time and high testing costs. It achieves the technical effect of providing vehicle development and testing personnel with a simple and fast testing method for verification testing of scenario services, reducing the waiting time for test scenarios, and reducing the cost of development and testing.

[0082] Figure 3 This is a schematic diagram of the structure of a simulation test system provided by this application. Figure 3 As shown, the simulation test system includes: a data simulation service module 41, a test engine 42, a message bus 43 and a simulation monitoring background 44.

[0083] The data simulation service module 41 includes a configuration management module 411 and a simulation data management module 412. The simulation data management module 412 comprises configuration read and validation, simulation data generation, and data transmission. Data transmission is driven by configuration validation and the association of simulation data. Simulation data must reference the data format and business values ​​of real business data sources, including data encoding, data type, and business significance of the values.

[0084] The test engine 42 includes a calculation module 421 and a data queue management module 422 .

[0085] The simulation monitoring background 44 can display the following contents to the developer: intelligent interaction 441 , simulation data log 442 , scenario calculation log 443 and scenario subscription notification 444 .

[0086] Below through Figure 4 The illustrated embodiment is used to illustrate how each module in the simulation test system works.

[0087] Figure 4 This is a flow chart of another vehicle usage scenario simulation test method provided in an embodiment of the present application. Figure 4 As shown, the vehicle scenario simulation test method is applied to Figure 3 The simulation test system shown includes the following steps:

[0088] S401: Acquire and parse simulation configuration information input by a developer.

[0089] In this step, the simulation configuration information includes: data configuration, simulation mode configuration and transmission configuration information.

[0090] In this embodiment, the data configuration is used to indicate various vehicle usage scenarios that need to be simulated, that is, to specify the corresponding simulation protocol.

[0091] The simulation mode configuration is set up for multiple vehicle usage scenarios or stress tests.

[0092] The transmission configuration information includes one or more transmission frequencies for transmitting scenario simulation data and one or more transmission start times corresponding to each transmission frequency. The transmission frequencies are used to test and verify the test vehicle's processing pressures for different data volumes.

[0093] In this embodiment, if Figure 3 As shown, the configuration management module 411 in the data simulation service module 41 receives the simulation configuration information submitted by the user.

[0094] It is worth noting that the configuration data in the configuration management module 411 includes: preset configuration data and system file replacement configuration data. The content of the configuration data includes three parts: simulation data configuration file, mode configuration file, and frequency configuration file. The data simulation service module 41 will enable the preset configuration data by default when the simulation test system is installed. It should be noted that the file corresponding to the configuration data is a json file. When the developer modifies the data of the configuration file in the operation interface and submits the configuration data, the configuration management module 411 will preferentially load the configuration file to replace the preset configuration data.

[0095] For ease of understanding, Table 1 exemplifies several configuration parameter examples in the simulation configuration information:

[0096]

[0097]

[0098] Table 1

[0099] It should be noted that Table 1 lists the key parameters of simulation data. Developers can simply connect to the data they want to simulate, configure specific simulation data codes and business values, and then add or modify simulation data. They can also query and delete unnecessary simulation data as needed.

[0100] S402. Determine one or more vehicle usage scenarios corresponding to the scenario configuration data, and the type and value range of each parameter in the scenario configuration data according to the data configuration.

[0101] In this embodiment, if Figure 3 As shown, the configuration management module 411 performs configuration validation processing on the three aspects of configuration, namely, data configuration, simulation mode configuration and transmission configuration information, and sends them to the simulation data management module 412 .

[0102] In this step, the simulation data management module 412 reads the data configuration, verifies the validity of the data configuration, and then loads the scenario configuration data corresponding to the data configuration, that is, various parameters.

[0103] S403: Determine the simulation sequence and switching method of each vehicle usage scenario according to the simulation mode configuration.

[0104] In this embodiment, the developer sets up multiple vehicle usage scenarios, and then needs to specify the switching method of each vehicle usage scenario. The switching methods include: manual switching, automatic random switching, and automatic switching according to simulation sequence.

[0105] For ease of understanding, Table 2 exemplarily provides several examples of simulation mode configuration parameters in the simulation configuration information:

[0106]

[0107]

[0108] Table 2

[0109] Specifically, the simulation data management module 412 reads the simulation mode configuration, verifies the validity of the simulation mode configuration, and then sets corresponding parameters in the scenario configuration data according to the simulation mode configuration.

[0110] S404: Determine scene simulation data according to the scene configuration data and a preset scene simulation protocol.

[0111] In this step, after the parameters corresponding to the configuration information are loaded, the scenario simulation protocol corresponding to each vehicle usage scenario is used to generate scenario simulation data according to the configuration parameters.

[0112] S405 : Send scenario simulation data to the test engine at each start transmission time and at its corresponding transmission frequency.

[0113] In this embodiment, for ease of understanding, Table 3 exemplarily provides examples of configuration parameters of several transmission frequencies in the simulation configuration information:

[0114] parameter describe Numerical configId Configuration Code Id frequency configName Configuration Name frequency configValue Configuration Values 1000 description Configuration Description Frequency in milliseconds configId Configuration Code Id startTime configName Configuration Name Start time configValue Configuration Values 022-01-03 09:10:05 description Configuration Description Year Month Day Hour Minute Second

[0115] Table 3

[0116] It should be noted that after all simulation business data is loaded, the queue will be sorted according to the priority of the scenario simulation data to ensure that the scenario simulation data is sent to the test engine in a reasonable order. The lower the priority value, the higher the priority will be, and it will be sent first.

[0117] S406: Verify the legitimacy of the scene simulation data.

[0118] In this step, if the verification result is legal, S407 is executed; if not, the scene simulation data is discarded.

[0119] It should be noted that after simulation data has been generated, if the developer temporarily changes the simulation intent and needs to use a different vehicle scenario, that is, use new simulation data, but the original simulation data has already been sent, then the original simulation data can be discarded through the validation method. For example, after the developer submits the new simulation configuration in the operation interface, the new validation rules are simultaneously sent to the test engine.

[0120] S407: Switch the vehicle usage scenario according to the scenario simulation data and start the test.

[0121] In this embodiment, scenario-based business developers and functional testers can use the test engine to verify specific business implementations and debug corresponding scenario interfaces. Upon startup, the test engine automatically monitors the bound data simulation service and prepares to receive scenario-based simulation data from the data simulation service module. The scenario-based simulation data uses the same data protocol as the actual business data source. The test engine verifies the data's legitimacy and triggers scenario changes through the calculation engine. This allows for reliable and efficient verification of scenario-based business logic.

[0122] S408: Synchronize the test data of the test engine to the simulation monitoring background to determine and store the test record log.

[0123] In this step, the test data is sent to the scene message bus, so that the simulation monitoring background reads the test data through the scene message bus.

[0124] In this embodiment, taking the highway driving scenario as an example, the test engine will sequentially receive data of high-speed driving and 90 kilometers per hour, with an interval of 1000 milliseconds (1 second). After receiving the above scenario simulation data, the high-speed scenario will be triggered, and the corresponding synchronous message bus information will be updated to the data simulation monitoring background. Figure 3 The detailed information displayed in the simulation monitoring background 44 includes: smart card interaction 441, simulation data log 442, scenario calculation log 443, and scenario subscription notification 444. Developers and testers can use this to clearly and conveniently verify scenario services and debug related functional interfaces, greatly reducing the cost of business development.

[0125] This embodiment provides a vehicle usage scenario simulation test system method, which obtains and parses the simulation configuration information input by the developer; according to the parsing result of the simulation configuration information, loads the scenario configuration data corresponding to the simulation configuration information, and determines the scenario simulation data according to the scenario configuration data and the preset scenario simulation protocol; according to the transmission configuration information in the parsing result, sends the scenario simulation data to the test engine to change the vehicle usage scenario in the test engine, and tests the various preset services corresponding to the vehicle usage scenario. It solves the technical problem in the prior art that the vehicle usage scenario is uncontrollable during vehicle research and development testing, resulting in long research and development time and high testing costs. It achieves the technical effect of providing vehicle development and testing personnel with a simple and fast testing method for verification testing of scenario services, reducing the waiting time for test scenarios, and reducing the cost of development and testing.

[0134] Determine one or more vehicle usage scenarios corresponding to the scenario configuration data, as well as the type and value range of each parameter in the scenario configuration data, based on the data configuration.

[0135] In one possible design, the simulation configuration information further includes: simulation mode configuration, and the processing module 502 is further configured to:

[0136] When there are multiple vehicle usage scenarios, the simulation order and switching method of each vehicle usage scenario are determined according to the simulation mode configuration. The switching methods include: manual switching, automatic random switching, and automatic switching according to the simulation order.
