If the module signaling interaction message indicates that the communication connection between the target vehicle and the target base station is normal, then the network connection of the target vehicle is determined to be normal; if the module signaling interaction message indicates that the communication connection between the target vehicle and the target base station is abnormal, then the network connection of the target vehicle is determined to be abnormal.

This application does not limit specific application scenarios, and any scheme using the vehicle network connectivity testing methods and apparatus provided in this application is within the protection scope of this application.

[0023] It is worth noting that with the rapid development of the connected vehicle ecosystem, the widespread adoption of in-vehicle services such as navigation and intelligent driving has significantly increased users' reliance on vehicle connectivity. In practice, after vehicles have been parked for extended periods and entered a dormant state, network connectivity issues frequently occur upon restarting. However, current vehicle testing in the industry mainly focuses on communication protocol consistency verification and system-level simulation testing, lacking testing of the entire vehicle's network connectivity capabilities, which refers to maintaining network connectivity.

[0024] To address the aforementioned issues, this application proposes a testing method, system, device, and storage medium for vehicle network connectivity. Through multi-dimensional collaborative verification, it improves the reliability of the network connectivity function and the stability of the user experience. Furthermore, it achieves automated testing of network connectivity capabilities and can pinpoint the causes of network connection failures.

[0025] To facilitate understanding of this application, the technical solutions provided in this application will be described in detail below with reference to specific embodiments.

[0026] Existing testing methods generally rely on manual operation to complete the hibernation and wake-up process, log recording, and status judgment. This not only leads to low efficiency in long-term stress testing, but also poses risks of incomplete data collection and misjudgment, making it difficult to meet the system reliability verification requirements in complex application scenarios.

[0027] Please see Figure 1 , Figure 1 This is one of the flowcharts for a vehicle network connectivity test method provided in an embodiment of this application.

[0028] In this embodiment of the application, the vehicle network connectivity testing method is applied to a host computer, such as... Figure 2 As shown, the host computer establishes a communication connection with the target vehicle through OBD wired connection, ADB wired connection and Wi-Fi wireless connection.

[0029] like Figure 1 As shown in the figure, the vehicle network connectivity testing method provided in this application embodiment includes the following steps: Step S101: Control the target vehicle to generate an echo request message to determine whether the target vehicle and the network server are in a communication connection.

[0030] Here, this application uses a Ping (Internet Packet Explorer) test to determine whether the target vehicle and the network server are communicating. Specifically, this step involves controlling the gateway of the target vehicle to generate an echo request message and sending it to the network server.

[0031] In one possible implementation, such as Figure 3 As shown, prior to step S101, the test method further includes: S1. Control the target vehicle to wake up. Here, the host computer connects to the target vehicle's OBD interface via CANOE and sends a wake-up message to the vehicle through the OBD interface. The target vehicle wakes up after receiving the wake-up message.

[0032] S2. Control the target vehicle to apply high voltage power. Here, a high voltage power-on message is sent to the vehicle through the OBD interface, and the target vehicle applies high voltage power after receiving the high voltage power-on message.

[0033] In one possible implementation, after step S2, the testing method further includes: S3. Obtain the network icon of the target vehicle to indicate whether the network connection status of the target vehicle is normal.

[0034] Here, in the target vehicle's infotainment system, the network icon's network connection status refers to whether the target vehicle's T-BOX (communication terminal) has successfully established a communication connection with the target base station. If the target vehicle's T-BOX successfully establishes a communication connection with the target base station, the T-BOX sends a T-BOX network connection success signal to the target vehicle's infotainment system via Ethernet. In response to this signal, the target vehicle's infotainment system generates a network icon indicating a normal network connection status. If the target vehicle's T-BOX fails to establish a communication connection with the target base station, the infotainment system generates a network icon indicating an abnormal network connection status. In this application, the host computer obtains the network icon through the ABD interface.

[0035] S4. If the obtained network icon indicates that the network connection status of the target vehicle is abnormal, a first test report is generated to indicate that the network connection test has failed.

[0036] Here, the network icon indicates that the target vehicle's network connection status is abnormal, which may be caused by the following two situations: The first situation is that if the target vehicle's T-BOX has successfully established a communication connection with the target base station, the abnormality may occur during the signal transmission between the T-BOX and the vehicle's infotainment system; the second situation is that the target vehicle's T-BOX has not successfully established a communication connection with the target base station.

[0037] S5. If the obtained network icon indicates that the network connection status of the target vehicle is normal, then control the target vehicle to generate an echo request message to determine whether the target vehicle is connected to the network server.

[0038] See again Figure 1 Step S102: Determine whether the target vehicle has received a response message from the network server within a preset time period.

[0039] Here, the response message is generated by the network server after receiving the echo request message. Specifically, when the network server receives the echo request message, it generates a response message and sends it to the gateway of the target vehicle.

[0040] Step S103: If it is determined that the target vehicle receives the response message within a preset time period, then it is determined that the network connection of the target vehicle is normal.

[0041] Step S104: If it is determined that the target vehicle has not received the response message within a preset time period, then obtain the module signaling interaction message in the target vehicle used to indicate whether the target vehicle and the target base station are in communication connection.

[0042] Here, the host computer obtains module signaling interaction messages by connecting to the T-BOX via Wi-Fi.

[0043] Step S105: If the module signaling interaction message indicates that the target vehicle and the target base station have a normal communication connection, then it is determined that the network connection of the target vehicle is normal.

[0044] Here, if the module signaling interaction message indicates that the communication connection between the target vehicle and the target base station is normal, it means that the network server is abnormal.

[0045] Step S106: If the module signaling interaction message indicates that the communication connection between the target vehicle and the target base station is abnormal, then it is determined that the network connection of the target vehicle is abnormal.

[0046] In one possible implementation, the testing method further includes: if it is determined that the network connection of the target vehicle is abnormal, generating a first test report to indicate that the network connection test has failed; if it is determined that the network connection of the target vehicle is normal, generating a second test report to indicate that the network connection test has passed.

[0047] In one possible implementation, the testing method further includes: after determining the network connectivity test result of the target vehicle, controlling the target vehicle to power down; after waiting for a preset time, returning to step S1 to perform the network connectivity test of the target vehicle again, ensuring the comprehensiveness and reliability of the test. Here, the vehicle re-enters sleep mode after waiting for the preset time. As an example, the preset time is 15 minutes.

[0048] In this application, after determining that the target vehicle's network connection is abnormal, the target vehicle's logs containing test data are obtained and appended to the test report. These test data logs include T-BOX logs, infotainment system logs, and gateway logs to ensure the integrity and traceability of the network connection test results.

[0049] This application provides a method for testing vehicle network connectivity, which improves the reliability of network access functionality and the stability of user experience. Furthermore, it automates network access capability testing and can pinpoint the causes of network connection failures.
