[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0030] The following description, with reference to the accompanying drawings, outlines a vehicle-to-everything (V2X) performance testing method, apparatus, testing tool, and storage medium according to embodiments of this application. Addressing the problems mentioned in the background section, this application provides a V2X performance testing method. This method is applied to a testing tool, which incorporates a plugin required for V2X performance testing. The plugin's V2X communication protocol simulates concurrent connections of user vehicles to a V2X platform. A test script adapted to the plugin and the V2X communication protocol is written to simulate login and event messages recognizable by the V2X platform. By concurrently reporting a large number of login and event messages, the throughput, response time, and stability of the V2X performance are verified. This solves the problem in related technologies where testing tools cannot flexibly generate various types of messages reported by vehicles to meet the requirements of V2X performance testing.

[0031] Specifically, Figure 1 This is a flowchart illustrating a vehicle network performance testing method provided in an embodiment of this application.

[0032] like Figure 1 As shown, the vehicle-to-everything (V2X) performance testing method includes the following steps:

[0033] In step S101, the plugins required for vehicle networking performance testing are introduced into the testing tool.

[0034] Understandably, to simulate the data reported by the vehicle in the testing tool, it is necessary to introduce the plugins required for vehicle network performance testing, such as the protobuf protocol plugin, MQTT (Message Queuing Telemetry Transport) middleware plugin, and protocol conversion JAR package plugin.

[0035] In step S102, the vehicle network communication protocol carried by the plug-in is used to simulate one or more vehicle users connecting to the vehicle network platform, and a test script adapted to the plug-in and the vehicle network communication protocol is written. The test script is used to simulate login messages and event messages that the vehicle network platform can recognize.

[0036] Understandably, vehicle-to-everything (V2X) platforms typically use protobuf as the encoding / decoding protocol and MQTT as the message transmission protocol. The raw data reported by the vehicle is deserialized into JSON format, which the system recognizes, using the protobuf protocol for processing. Therefore, this embodiment can use testing tools to start multi-threading, simulating multiple vehicle users and establishing communication links with the MQTT server. The success of the link establishment can be observed through the EMQ dashboard. Furthermore, the test scripts included in the plugin can flexibly generate and convert messages. By concurrently reporting large batches of remote control events and periodic signals, the throughput, response time, and stability of the V2X performance can be verified.

[0037] In one embodiment of this application, a test script is used to simulate login messages and event messages that can be recognized by the vehicle networking platform, including: creating a first target format message and a second target format message according to the test script; converting the first target format message into a login message that can be recognized by the vehicle networking platform; and converting the second target format message into an event message that can be recognized by the vehicle networking platform.

[0038] This embodiment of the application can write a proto file in the testing tool according to the vehicle-to-everything (V2X) communication protocol, create a target format message (JSON format message) based on the proto file, and convert the target format message generated in the previous step into a message that the V2X platform can recognize. When creating the target format message, this embodiment of the application can introduce variable parameters to enrich the test data.

[0039] Specifically, this application embodiment can develop test scripts for adapting the plugin and the vehicle-to-everything (V2X) communication protocol. These test scripts generate simulated vehicle-reported login messages, generate Java object data to be sent according to the protobuf protocol, convert it into a byte stream, and then convert it into a login message recognizable by the V2X platform. The login message includes information such as the vehicle terminal TBOX and SIM card. Furthermore, the test scripts carried by the plugin generate simulated vehicle-reported event messages, generate Java object data to be sent according to the protobuf protocol, convert it into a byte stream, and then convert it into an event message recognizable by the V2X platform.

[0040] In step S103, the vehicle network performance of the vehicle network platform is tested using login messages and event messages.

[0041] To ensure the timeliness and accuracy of vehicle-reported data processing, this application embodiment can send simulated login messages and event messages to the vehicle network platform for testing. Based on the feedback results from the vehicle network platform, the test results of the vehicle network performance test are determined to comprehensively evaluate the performance of the current vehicle network service.

[0042] In one embodiment of this application, sending a login message and an event message to the vehicle network platform includes: after successfully logging into the vehicle network platform using the login message, reporting an event message to the vehicle network platform.

[0043] Understandably, during vehicle-to-everything (V2X) performance testing, a simulated vehicle can log in to the V2X platform using a login message. After receiving the login request, the V2X platform replies with a test thread response message. Only after the simulated vehicle successfully logs in to the platform can the simulated vehicle's event messages be reported to the V2X platform for testing.

[0044] In one embodiment of this application, determining the test result of the vehicle network performance test based on the feedback result of the vehicle network platform includes: identifying a preset identifier in the response message fed back by the vehicle network platform; determining the error rate of vehicle login based on the preset identifier, wherein if the preset identifier is identified, it is determined that the login to the vehicle network platform is successful; otherwise, it is determined that the login to the vehicle network platform has failed and an error is reported.

[0045] The preset identifier can be a marker indicating whether the simulated vehicle has successfully logged in.

[0046] In this embodiment, after receiving the login message, the vehicle-to-everything (V2X) platform sends a response message containing a token. At this point, an assertion is added to the testing tool to determine whether the login to the platform was successful. In actual execution, this embodiment can determine whether the simulated vehicle has successfully logged in based on a preset identifier in the response message. If the preset identifier exists in the response message, the login to the V2X platform is considered successful; otherwise, the simulated login to the V2X platform is considered a failure and an error is reported. When the simulated vehicle fails to log in to the V2X platform, no event message can be reported to the V2X platform.

[0047] Furthermore, in this embodiment of the application, the statistical window of the testing tool can be used to count the number of event messages reported to the vehicle network platform, the success rate, and the test duration; the vehicle network performance can be comprehensively evaluated based on one or more of the number of messages, the success rate, and the test duration.

[0048] Furthermore, embodiments of this application can also determine whether the performance of the vehicle network meets the standards by observing the consumption rate of the MQTT middleware, the backlog situation, and the resource utilization rate of the service.

[0049] The following is combined with Figure 2 This application provides a detailed description of the vehicle network performance testing method according to embodiments of the present application. Vehicle network platforms typically use protobuf as the encoding / decoding protocol and MQTT as a middleware plugin. The method deserializes the raw hexadecimal data reported by the vehicle into a system-recognizable JSON format using the protobuf protocol, and includes the following steps:

[0050] 1. Import the relevant business JAR files and protobuf protocol JAR files into the testing tool via plugins.

[0051] 2. Create JSON format messages in the testing tool according to the protobuf protocol.

[0052] 3. Convert the JSON format message generated in the previous step to hexadecimal.

[0053] 4. Start multi-threading using testing tools to establish a communication link with the MQTT server.

[0054] 5. Using testing tools, simulate an MQTT producer and send the above-mentioned hexadecimal login message to the vehicle networking platform. After receiving the login request, the platform replies with a test thread response message.

[0055] 6. Using testing tools, simulate an MQTT producer to send the aforementioned hexadecimal events or periodic messages to the vehicle networking platform. After receiving the messages, the platform responds, thereby statistically analyzing the success rate of message transmission.

[0056] 7. Confirm the effective concurrency through the EMQ connection count.

[0057] 8. Service performance monitoring can be performed by observing the number of packets sent per unit time, throughput, test duration, success rate, etc., through the statistics window of the testing tool itself. Additionally, Grafna can be used to monitor server message consumption speed, as well as server memory, CPU, and other metrics.

[0058] The vehicle-to-everything (V2X) performance testing method proposed in this application introduces a plugin required for V2X performance testing into the testing tool. The plugin's V2X communication protocol simulates concurrent connections of user vehicles to the V2X platform. Test scripts adapted to the plugin and the V2X communication protocol are written to simulate login and event messages recognizable by the V2X platform. By concurrently reporting a large number of login and event messages, the throughput, response time, and stability of the V2X performance are verified. This solves the problem in related technologies where testing tools cannot flexibly generate various types of messages reported by vehicles to meet the needs of V2X performance testing.

[0059] Next, referring to the accompanying drawings, a vehicle networking performance testing device according to an embodiment of this application is described, which is applied to testing tools.

[0063] In one embodiment of this application, the simulation module 200 is further configured to create a first target format message and a second target format message according to the test script; convert the first target format message into a login message recognizable by the vehicle networking platform; and convert the second target format message into an event message recognizable by the vehicle networking platform.

[0064] In one embodiment of this application, the test module 300 includes a sending unit and a determining unit.

[0065] The sending unit is used to send login messages and event messages to the vehicle network platform; the determining unit is used to determine the test results of the vehicle network performance test based on the feedback results from the vehicle network platform.

[0066] In one embodiment of this application, the determining unit is further configured to identify a preset identifier in the response message fed back by the vehicle network platform; and determine the error rate of vehicle login based on the preset identifier, wherein if the preset identifier is identified, it is determined that the login to the vehicle network platform is successful; otherwise, it is determined that the login to the vehicle network platform has failed and an error is reported.

[0067] In one embodiment of this application, the determining unit is further configured to count the number of event messages reported to the vehicle network platform, the success rate, and the test duration; and to determine the vehicle network performance based on one or more of the number of messages, the success rate, and the test duration.

[0068] In one embodiment of this application, the determining unit is further configured to use the statistics window of the testing tool to count the number of messages, success rate, and test duration.

[0069] In one embodiment of this application, the sending unit is further configured to report an event message to the vehicle network platform after successfully logging into the vehicle network platform using the login message.

[0070] It should be noted that the foregoing explanation of the vehicle network performance testing method embodiment also applies to the vehicle network performance testing device of this embodiment, and will not be repeated here.

It utilizes the V2X communication protocol carried by the plugin to simulate concurrent connections of user vehicles to the V2X platform. Test scripts adapted to the plugin and the V2X communication protocol are written to simulate login and event messages recognizable by the V2X platform. By concurrently reporting a large number of login and event messages, the throughput, response time, and stability of the V2X performance are verified. This solves the problem in related technologies where testing tools cannot flexibly generate various types of messages reported by vehicles to meet the needs of V2X performance testing.
