Currently, this is mainly done by using different vehicle models as target test vehicles. The vehicle's onboard information terminal (Telematics-BOX, T-BOX) uploads the collected data to the cloud for vehicle testing. However, this testing method requires the use of physical vehicles. When there are many models to be tested, each model needs to be configured, and the T-BOX must already be installed in the vehicle, which affects the efficiency of vehicle testing and vehicle production line rollout.

Detailed Implementation
[0017] Currently, during vehicle testing, the process begins with testers configuring vehicle data acquisition commands in the cloud and sending them to the in-vehicle infotainment system of the target test vehicle. These commands specify the data to be collected and the data acquisition conditions. The vehicle receives these commands via a T-BOX, configures its data acquisition system accordingly, and uploads the collected data to the cloud via the T-BOX. The vehicle testing system, configured in the cloud, then performs vehicle testing based on the received data.
[0018] When there are many vehicle models to be tested, it is necessary to configure and issue vehicle data collection commands for each model. The vehicles need to collect data for a period of time and upload it to the cloud, which prolongs the vehicle testing time and reduces testing efficiency. Each vehicle model requires the T-BOX to be installed and configured to receive vehicle data collection commands and upload data. This means that if the T-BOX is not installed or not properly debugged, vehicle testing cannot be performed, affecting the efficiency of vehicle production line rollout.
[0019] In view of the above-mentioned problems existing in the prior art, the present invention provides a vehicle simulation testing method, a vehicle simulation server, a vehicle testing terminal, and a system.
[0020] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0021] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.
[0022] Figure 1 This is a schematic diagram illustrating the main steps of a vehicle simulation testing method according to an embodiment of the present invention. Figure 1 As shown, the vehicle simulation testing method of this invention, applied to a vehicle simulation server, mainly includes the following steps: Step S101: Call the target data template corresponding to the target vehicle type; The vehicle simulation server can be configured in the cloud, and it can simulate the data processing, usage, and data transmission links in the in-vehicle systems of different vehicle types.
[0023] The vehicle simulation server can be configured with data templates corresponding to multiple vehicle types to facilitate data configuration. This eliminates the need to simulate the existing technology of configuring vehicle data acquisition commands from the cloud and sending them to the vehicle's infotainment system, as well as the data acquisition configuration process based on these commands. After determining the target vehicle type for testing, the target data template corresponding to that vehicle type can be called from among the multiple data templates to populate and configure the target data template, thus determining the test data.
[0024] Step S102: Determine the test data for the target vehicle type based on the target data template. Step S103: Send the above test data to the vehicle test terminal so that the vehicle test terminal can perform vehicle testing based on the above test data.
[0025] The vehicle testing terminal can also be configured in the cloud. It can be used to perform vehicle testing based on test data sent by the vehicle simulation server, or it can perform vehicle testing based on data sent by the test vehicle.
[0026] By configuring the vehicle simulation server and vehicle testing terminal in the cloud, the vehicle simulation server generates test data and sends it to the vehicle testing terminal for vehicle testing (during which interaction can be achieved through the corresponding webpage or application on the vehicle testing terminal). This allows the entire vehicle testing process to be completed in the cloud. The vehicle simulation server can generate test data for various vehicle models, which is relatively simple and improves testing efficiency. Furthermore, it eliminates the need for vehicles equipped with T-BOX and various physical vehicle models, thus not affecting the efficiency of vehicle production line rollout.
[0027] In an optional embodiment, the method further includes: setting a virtual Internet Protocol Address (IP address) for the vehicle simulation server and establishing a connection between the virtual Internet Protocol Address of the vehicle simulation server and the Internet Protocol Address of the vehicle test terminal, so that the vehicle simulation server and the vehicle test terminal establish a communication link.
[0028] Configure a virtual IP address for the vehicle simulation server so that the vehicle simulation server and the vehicle test terminal can exchange data after establishing a communication link, making it easier for the vehicle simulation server to send test data to the vehicle test terminal.
[0029] A virtual IP address refers to a special-purpose IP address created using network technology on top of a real physical IP address. It is not exclusive to a specific network interface card (NIC) on a particular device and does not require binding to actual hardware. When the vehicle simulation server is configured with a virtual IP, if it switches to a backup cloud virtual server due to server migration or instance expansion, only the virtual IP address mapping needs to be updated from the old endpoint to the new endpoint. The vehicle testing client does not need any configuration changes and continues to access the vehicle simulation server through the same virtual IP address. This avoids problems such as frequent changes to the access address of the vehicle testing client or communication interruptions caused by changes in the vehicle simulation server's real IP address.
[0030] It should be noted that the IP address of the vehicle testing terminal can be either a virtual IP address or a real IP address; no specific restrictions are imposed here. The communication connection method can be customized and is not limited in any way.
[0031] Furthermore, establishing a communication link between the vehicle simulation server and the vehicle testing terminal is not limited to configuring a virtual IP address for the vehicle simulation server and an IP address for the vehicle testing terminal. For example, the communication link can be established using MQTT (Message Queuing Telemetry Transport).
[0032] As an example, the vehicle simulation server can send a message containing the above test data to a specified message topic, and the vehicle testing client can subscribe to the message topic to consume it, thus decoupling the vehicle simulation server and the vehicle testing client.
[0033] In an optional embodiment, the method further includes: pre-constructing a test database comprising multiple data templates; each data template corresponding to a vehicle type to be tested; constructing multiple signal sources for the vehicle type included in each data template and a signal value range for each signal source; wherein the vehicle type includes model and year; and configuring the test database on the vehicle simulation server.
[0034] The test database can include data templates corresponding to multiple vehicle types to be tested. Each data template can be configured to include multiple signal sources for that vehicle type and the signal value range for each signal source. "Vehicle model" refers to the vehicle's model number, and "year model" refers to the different year models corresponding to a specific vehicle model.
[0035] The signal sources include sensor signal sources, control unit signal sources, and input signal sources corresponding to the type of vehicle under test. In the test database, different signal sources are represented by pre-defined signal source identifiers. Among them, sensor signal sources can represent various sensors configured in the actual vehicle, such as vehicle speed sensors, engine speed sensors, temperature sensors, and rain sensors; control unit signal sources can represent various control units that can output operating status, fault information, etc. during the operation of the actual vehicle, such as engine control unit, transmission control unit, and body control module; input signal sources can represent the vehicle key, in-vehicle central control screen, and terminals logged into the vehicle's associated account that the driver can use to input commands during the use of the actual vehicle.
[0036] As an example, such as Figure 2 As shown, the test database can include data templates corresponding to four vehicle types to be tested: Model A, Model B, Model C, and Model D. Figure 3 As shown, vehicle models A and B can each include multiple model years. Model A includes the 2020 and 2023 model years, while model B includes the 2024 and 2025 model years. After a user selects the 2020 model year of vehicle model A as the target vehicle type, they can proceed to... Figure 4 The interface shown displays the data template for the 2020 model of vehicle A. This data template includes four signal sources and their respective signal value ranges: the first signal source RTM-D1 and its signal value range 0~100, the second signal source RTM-D2 and its signal value range 0~101, the third signal source RTM-D3 and its signal value range 0~6000, and the fourth signal source RTM-D4 and its signal value range 0~2000.
[0037] By configuring a test database containing multiple data templates for the vehicle simulation server, the target data template can be determined from among the multiple data templates according to the target vehicle type, and then the test data can be determined. The data templates are used to form a common parsing logic, avoiding the problem of data errors caused by users setting the test data completely by themselves, which affects the vehicle test results.
[0038] In one optional embodiment, determining the test data for the target vehicle type based on the target data template includes: searching for a target data template that matches the target vehicle type from a plurality of the data templates; and generating test data for the target type based on each signal source set in the target data template and the corresponding signal value.
[0039] Each vehicle type corresponds to at least one data template. After determining the target data template matching the target vehicle type, the signal source matching the target vehicle testing objective and the signal value can be determined and set according to the target vehicle testing objective of this vehicle test. Test data generated using the aforementioned data template has a unified format, simplifying the data generation logic and greatly improving the efficiency of test data generation. The vehicle testing objective refers to the data verification purpose of the current vehicle test, including but not limited to basic calculation result accuracy testing, data fusion correctness testing, correction algorithm testing, outlier filtering testing, data collaborative operation testing, data transmission packet loss rate testing, data transmission latency testing, data priority testing, data duplication testing, data encryption testing, and data format testing. The vehicle testing objective for each vehicle test can be set according to the current testing process or defined manually.
[0040] As an example, for a 2020 model year vehicle of type A, the user can, for example... Figure 5 In the interface shown, select the required signal sources RTM-D2 and RTM-D3 based on the target vehicle testing objective, and then... Figure 6 The interface shown allows setting signal values within the signal value range of RTM-D2 and RTM-D3, specifically setting the signal value of RTM-D2 to 56 and the signal value of RTM-D3 to 4000, in order to generate test data for vehicle testing of the aforementioned target vehicle type.
[0041] Optionally, determining the test data for the target vehicle type based on the target data template includes: for a certain vehicle type, receiving one or more signal sources and corresponding signal values selected by the user from the test database, generating a custom data template corresponding to the vehicle type; and determining test data for the vehicle type based on the custom data template.
[0042] There can be multiple data templates for each vehicle type. Users can pre-select the associated signal source and corresponding signal value or signal value range from the test database for the vehicle test purpose to obtain custom data templates for different vehicle test purposes, and each custom data template corresponds to a vehicle test purpose.
[0043] The system selects a target data template from multiple custom data templates based on the target vehicle type and the purpose of the test. When the target data template includes signal values, after selecting the template, the user does not need to reset the signal values for each signal source because the template already contains the corresponding signal values; the test data can be directly determined based on the target data template. When the target data template includes a range of signal values, after selecting the template, the user can set the signal values for each signal source within its range to determine the test data.
[0044] As an example, such as Figure 7 As shown, the target vehicle type is the 2020 model of vehicle type A. There are five custom data templates: Custom Data Template M1, Custom Data Template M2, Custom Data Template M3, Custom Data Template M4, and Custom Data Template M5. Each custom data template corresponds to a vehicle testing objective. The vehicle testing objective for Custom Data Template M1 is to test the accuracy of basic calculation results; the vehicle testing objective for Custom Data Template M2 is to test the correctness of data fusion; the vehicle testing objective for Custom Data Template M3 is to test the algorithm correction; the vehicle testing objective for Custom Data Template M4 is to test outlier filtering; and the vehicle testing objective for Custom Data Template M5 is to test the data transmission packet loss rate. When the target vehicle's testing objective is to test the data transmission packet loss rate, Custom Data Template M5 is selected as the target data template. The display interface after calling Custom Data Template M5 is as follows: Figure 8 As shown, the signal sources in the custom data template M5 are RTM-D2 and RTM-D4. The signal value of signal source RTM-D2 is 35, and the signal value of signal source RTM-D4 is 1500.
[0045] By setting multiple data templates for each vehicle type, and each data template corresponding to a vehicle testing objective, once the target vehicle type and the current vehicle testing objective are determined, the corresponding target data template can be directly called to determine the test data, further simplifying the method of determining test data and streamlining the test data generation process.
[0046] In one optional embodiment, test data for different vehicle types is configured with corresponding data transmission formats to differentiate test data for different vehicle types. The data transmission format refers to the standardized data organization format in which test data is encapsulated and encoded during data transmission from the vehicle simulation server to the vehicle testing terminal. In the prior art, this corresponds to the standard data organization format used in the process of data transmission from a physical vehicle to the cloud-based vehicle testing terminal. A pre-defined association between vehicle type and data transmission format is established.
[0047] Specifically, the above method also includes: converting and encapsulating the generated test data according to the data transmission format associated with the target vehicle type.
[0048] Furthermore, during the format conversion process, an identifier for the target vehicle type can be added so that the converted and packaged test data includes the target vehicle type identifier, making it easier for the vehicle testing end to identify the target vehicle type.
[0049] In an optional embodiment, the method further includes storing the test data as a storage file in a target format.
[0050] Optionally, the target format can be JSON. JSON is a lightweight structured data storage format that is easy to parse and convenient for development and debugging.
[0051] In one optional embodiment, sending the test data to the vehicle test terminal may include sending the test data to the vehicle test terminal at a preset sending frequency.
[0052] According to the vehicle simulation testing method of this invention, a vehicle simulation server is established, and a target data template corresponding to the target vehicle type is called. Test data for the target vehicle type is determined according to the target data template. The test data is sent to the vehicle testing terminal so that the vehicle testing terminal can perform vehicle testing based on the test data. The vehicle testing method can be implemented entirely in the cloud. Test data for multiple vehicle models can be generated through the vehicle simulation server, which is relatively simple and improves testing efficiency. At the same time, it does not require the use of physical vehicles of multiple vehicle types, nor does it require the installation of T-BOX in the vehicle, thus avoiding the impact of vehicle testing on the efficiency of vehicle production and reducing vehicle testing costs.
[0053] Figure 9 This is a schematic diagram of the main modules of a vehicle simulation server according to an embodiment of the present invention. Figure 9 As shown, the vehicle simulation server 900 of this embodiment includes: a calling module 901, used to call a target data template corresponding to the target vehicle type; a determining module 902, used to determine test data for the target vehicle type according to the target data template; and a sending module 903, used to send the test data to the vehicle testing terminal so that the vehicle testing terminal performs vehicle testing based on the test data.
[0054] In an optional embodiment of the present invention, the vehicle simulation server 900 further includes: a setting module, configured to set a virtual Internet Protocol address for the vehicle simulation server and establish a connection between the virtual Internet Protocol address of the vehicle simulation server and the Internet Protocol address of the vehicle test terminal, so that the vehicle simulation server and the vehicle test terminal establish a communication link.
[0055] In an optional embodiment of the present invention, the vehicle simulation server 900 further includes: a construction module, configured to pre-construct a test database including multiple data templates; each data template corresponds to a vehicle type to be tested; construct multiple signal sources for the vehicle type included in each data template and the signal value range of each signal source; wherein the vehicle type includes model and year; and configure the test database in the vehicle simulation server.
[0056] In an optional embodiment of the present invention, the determining module 902 is further configured to search for a target data template matching the target vehicle type from a plurality of the above-mentioned data templates; and generate test data for testing the target type according to each of the above-mentioned signal sources and corresponding signal values set in the above-mentioned target data template.
[0057] In an optional embodiment of the present invention, the determining module 902 is further configured to receive one or more signal sources and corresponding signal values selected by the user from the test database for a certain vehicle type, generate a custom data template corresponding to the vehicle type, and determine test data for the vehicle type according to the custom data template.
[0058] In an optional embodiment of the present invention, test data for different vehicle types are configured with corresponding data transmission formats. The vehicle simulation server 900 further includes a conversion module, used to convert and encapsulate the generated test data according to the data transmission format associated with the target vehicle type.
[0059] In an optional embodiment of the present invention, the vehicle simulation server 900 further includes a storage module for storing the test data as a storage file in a target format.
[0060] According to the vehicle simulation server of the present invention, by establishing a vehicle simulation server, calling the target data template corresponding to the target vehicle type; determining test data for the target vehicle type based on the target data template; and sending the test data to the vehicle testing terminal so that the vehicle testing terminal can perform vehicle testing based on the test data, the vehicle testing method can be fully implemented in the cloud. Test data for multiple vehicle models can be generated through the vehicle simulation server, which is relatively simple and improves testing efficiency. At the same time, it does not require the use of physical vehicles of multiple vehicle types, nor does it require the installation of T-BOX in the vehicle, thus avoiding the impact of vehicle testing on the efficiency of vehicle production and reducing vehicle testing costs.

Figure 10 As shown, the vehicle test terminal 1000 of this embodiment includes: a receiving module 1001, used to receive test data sent by the vehicle simulation server of this embodiment; and a test module 1002, used to perform vehicle testing based on the test data.
[0062] The vehicle testing terminal 1000 of this embodiment can be configured in the cloud and is independent of the vehicle simulation server. It includes multiple application services, each corresponding to at least one vehicle testing objective. After receiving test data sent by the vehicle simulation server, the corresponding application service can be invoked based on the vehicle testing objective to perform vehicle testing on the test data and generate test results.
[0063] According to the vehicle testing terminal of the present invention, it can receive test data sent by the vehicle simulation server of the present invention and perform vehicle testing based on the test data. It can combine the vehicle simulation server to realize a completely cloud-based vehicle testing method without the need for physical vehicles, which greatly improves the vehicle testing speed, avoids the impact of vehicle testing on vehicle production line efficiency, and reduces vehicle testing costs.

[0067] The vehicle simulation server 1101 can call the target data template corresponding to the target vehicle type; determine the test data for the target vehicle type based on the target data template; and send the test data to the vehicle test terminal so that the vehicle test terminal can perform vehicle testing based on the test data.

The names of these modules do not necessarily limit the module itself; for example, the calling module can also be described as "a module that calls the target data template corresponding to the target vehicle type".
[0076] In another aspect, the present invention also provides a computer-readable medium, which may be included in the device described in the above embodiments; or it may exist independently and not assembled into the device. The computer-readable medium carries one or more programs that, when executed by the device, cause the device to: invoke a target data template corresponding to a target vehicle type; determine test data for the target vehicle type based on the target data template; and send the test data to a vehicle testing terminal, so that the vehicle testing terminal performs vehicle testing based on the test data.
[0077] According to the technical solution of this invention, by establishing a vehicle simulation server and calling the target data template corresponding to the target vehicle type; determining test data for the target vehicle type based on the target data template; and sending the test data to the vehicle testing terminal so that the vehicle testing terminal can perform vehicle testing based on the test data, the vehicle testing method can be fully implemented in the cloud. Test data for multiple vehicle models can be generated through the vehicle simulation server, which is relatively simple and improves testing efficiency. At the same time, it eliminates the need to use physical vehicles of multiple vehicle types and eliminates the need to install T-BOX in the vehicle, thus avoiding the impact of vehicle testing on the efficiency of vehicle production and reducing vehicle testing costs.
[0078] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
