[0002] With the continuous development of electronics, the connection methods between current diagnostic equipment (VCI, Vehicle Communication Interface) and PC (Personal Computer) diagnostic software are becoming increasingly diverse, with wired and wireless connections being the most common. Wired connections require physical cables, which not only limit distance but also depend on the quality of the hardware itself. If the cable is lost or damaged, diagnostics cannot be performed via the VCI. Wi-Fi communication, with its speed and convenience, has become the preferred diagnostic method. However, in current vehicle diagnostic work, many laptops only have a built-in wireless network card, while many diagnostic software programs require internet access, such as logging in, acquiring data online, and downloading / flashing files. When the laptop's built-in wireless network card is connected to the internet, it cannot connect to the diagnostic equipment's Wi-Fi, necessitating the use of an external wireless network card.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Currently, with the continuous development of electronic appliances, the connection methods between VCI (Vehicle Inspection Center) devices and PC diagnostic software are becoming increasingly diverse, with wired and wireless connections being common. Wired connections require physical wiring, which not only limits distance but also depends on the quality of the hardware itself. If the wire is lost or damaged, the connection to the VCI cannot be established for diagnosis. WIFI communication, with its speed and convenience, has become the preferred diagnostic method. However, in current vehicle diagnostic work, many laptops are only equipped with a built-in wireless network card, while many diagnostic software programs require internet access, such as logging in, acquiring data online, and downloading / writing files. When the laptop's built-in wireless network card connects to the internet, it cannot connect to the diagnostic device's WIFI, necessitating the use of an external wireless network card. This situation is not only extremely inconvenient but can also prevent diagnostic work from proceeding without an external wireless network card, severely impacting the efficiency and progress of vehicle diagnostics. To solve the above technical problems, this application discloses a vehicle diagnostic method, apparatus, device, and storage medium that can improve the efficiency of diagnostic equipment applications.

[0051] See Figure 1 As shown, this embodiment of the invention discloses a vehicle diagnostic method, applied to a physical machine with target diagnostic software installed, comprising:

[0052] Step S11: Determine the corresponding preset wireless network based on the network connection request, and verify the network connection request to connect to the preset wireless network; wherein, the preset wireless network includes an external wireless network and a diagnostic device wireless network.

[0053] In this embodiment, if it is the first time using the target diagnostic software, it is necessary to remove other interfering network card information and find the physical machine's built-in wireless network card. This can be done by scanning the network adapters in the physical machine; based on the scan results, pre-defined interfering network cards in the network adapters are eliminated to determine the target wireless network card; a first network connection request from the diagnostic device's wireless network is sent to the target wireless network card, so that the target wireless network card authenticates with the target diagnostic device based on the first network connection request, connects to the diagnostic device's wireless network based on the corresponding first authentication result, and sends first connection confirmation information to the target diagnostic software in the physical machine; a second network connection request from the external wireless network is sent to the target wireless network card, so that the target wireless network card authenticates with the external wireless network device based on the second network connection request, connects to the external wireless network based on the corresponding second authentication result, and sends second connection confirmation information to the target diagnostic software in the physical machine. Specifically, as shown below... Figure 2 As shown, when the target diagnostic software is used for the first time, it first calls the operating system's low-level interface to scan the physical machine's network adapters, eliminating preset interfering network cards in the network adapters to find the required target wireless network card. These preset interfering network cards include any one or more of the following: wired network cards, virtual network cards, Bluetooth network cards, and USB network cards. Then, as... Figure 3 As shown, a first network connection request is sent to the target wireless network card, specifically a request to the diagnostic device's network VCI_WIFI2. This request may include a static IP address, device IP address, and subnet mask. After the wireless network card matches the signal, it initiates authentication. If the diagnostic device verifies the information and it passes the authentication, it assigns an IP address and completes the connection. The target wireless network card then returns the connection result in JSON format, including status, IP address, signal strength, etc. The software updates the interface synchronously and provides error suggestions. After the first connection is successful, the software automatically or manually triggers a second network connection request, specifically a request to the external network Wireless_WIFI1, to obtain configuration information from the diagnostic device or for the user to enter the WIFI password. Simultaneously, the target wireless network card needs to maintain the diagnostic network connection while scanning for external signals. If the signal is weaker than -85dBm, a pop-up message appears. Authentication failure does not interrupt the existing connection; success establishes a dual network channel. The feedback information now includes a dual network compatibility status, which is displayed in the updated software, ensuring that the diagnostic function is not affected by external connection failures.

[0054] Additionally, if the first connection confirmation information indicates that the diagnostic device's wireless network connection has failed, a corresponding first prompt message is generated and sent to the user terminal; wherein, the first prompt message includes reconfiguring the diagnostic device's wireless network. If the second connection confirmation information indicates that the external wireless network connection has failed, a corresponding second prompt message is generated and sent to the user terminal; wherein, the second prompt message includes reconfiguring the external wireless network. Specifically, when the first connection confirmation information indicates that the diagnostic device's wireless network connection has failed, the target diagnostic software will generate a targeted first prompt message based on the returned error code. If the error code points to a key error, the prompt message will explicitly suggest that the user re-verify the diagnostic device's wireless network password, while providing an entry point for quickly jumping to the network configuration page; if the failure is due to a weak signal, it will prompt the user to check the distance between the physical device and the diagnostic device, suggesting that they be brought closer together to enhance the signal, and displaying the current signal strength value for reference. If the second connection confirmation information indicates that the external wireless network connection has failed, the generated second prompt message will provide corresponding suggestions based on the specific reason for the failure. If the corresponding SSID (Service Set Identifier) ​​does not exist, the user will be prompted to confirm the correctness of the external wireless network name, paying particular attention to capitalization; if authentication fails, in addition to suggesting that the password be re-entered, the user will also be prompted to check whether the encryption method matches.

[0055] Understandably, after the external wireless network and the diagnostic device's wireless network are successfully connected, the connection configuration information of both is saved locally on the diagnostic instrument so that when connecting to the external wireless network and the diagnostic device's wireless network in the future, the corresponding wireless network can be directly connected through the connection configuration information.

[0056] Step S12: Use the diagnostic device's wireless network to send a read device command to the target diagnostic device and obtain the target diagnostic device serial number returned by the target diagnostic device.

[0057] In this embodiment, after successfully connecting to the diagnostic device's wireless network, the target diagnostic software generates a device read command conforming to a specific protocol. This command includes a command identifier, a length field, a CRC32 checksum, and a software identifier, ensuring the command's legality and integrity. The command is sent to the target diagnostic device's port through the diagnostic network channel. After verifying the command's legality, the target diagnostic device reads its serial number from its internal storage chip and encapsulates it into a response packet containing a response identifier, serial number, checksum, and device status. The target diagnostic software parses the response packet and verifies the target diagnostic device's serial number. If successful, the serial number is stored in a local configuration file and displayed on the interface as a unique identifier for subsequent operations. If unsuccessful, an exception is displayed and a log is logged.

[0058] Step S13: Turn off the diagnostic device's wireless network and switch to the external wireless network. Based on the user information obtained through the external wireless network verification and the target diagnostic device's serial number, obtain access permissions for the target diagnostic software.

[0059] In this embodiment, the target wireless network card is controlled to shut down the diagnostic device's wireless network, quickly switch to an external wireless network, enter the target diagnostic software login function, and then obtain the username and password sent by the user terminal. The username, password, and target diagnostic device serial number are sent to the target server so that the target server can verify them and send the verification result to the target diagnostic software in the physical machine. If the verification result indicates that the user terminal and the target diagnostic device meet preset trust conditions, then access to the target diagnostic software is granted. Specifically, when the target wireless network card shuts down the diagnostic device's wireless network, it first sends a disconnect command, releases the IP address, and records connection parameters for later reuse, then quickly reconnects based on the saved external wireless network configuration. After entering the login function, the software interface displays an account and password input box, supporting "remember password" and "auto-fill" functions. After the user submits the username and password, the software encrypts the password and combines it with the plaintext username and target diagnostic device serial number to form a verification data packet. The verification data packet is sent to the target server's verification interface via an external wireless network. Upon receiving the packet, the target server first checks whether the target diagnostic device's serial number is registered in the system, and then compares the username with the encrypted password and the user information stored in the database. If the serial number is not registered or the username and password do not match, the server returns a verification failure result with an explanation of the reason; if all three match and the device is bound to the user account, thus meeting the preset trust conditions, the server returns a verification success result, and the target diagnostic software immediately unlocks all functional modules, granting full access permissions.

[0060] Step S14: In the target diagnostic software, determine the target network requirement according to the diagnostic application scenario, determine the target wireless network from the preset wireless networks based on the target network requirement, and use the target wireless network to perform the corresponding preset diagnostic operation on the target vehicle.

[0061] In this embodiment, after obtaining full access to the target diagnostic software, the target network requirement is determined based on the diagnostic application scenario. This target network requirement includes diagnosing the target vehicle or upgrading the target diagnostic software. If the target network requirement is to diagnose the target vehicle, the diagnostic device's wireless network is identified as the target wireless network, and a preset diagnostic operation is performed on the target vehicle using the target wireless network. If the target network requirement is to upgrade the target diagnostic software, the external wireless network is identified as the target wireless network, and the target diagnostic software is updated using the target wireless network. Specifically, when performing a specific diagnostic function on the target vehicle, the external wireless network is automatically disconnected, and the diagnostic device's wireless network is connected. When targeting the target diagnostic software, the external wireless network is used. For example, if the target network requirement is to upgrade the target diagnostic software, an upgrade request containing the software version and device serial number is sent to the server using the external wireless network, and an upgrade installation package is received to upgrade the target diagnostic software.

[0062] Additionally, when the target diagnostic software exits, it needs to disconnect the diagnostic device's wireless network; connect to the external wireless network; generate corresponding target diagnostic logs for the diagnostic operations performed according to the target network requirements; and upload the generated target diagnostic logs to the target server using the external wireless network. Specifically, after receiving the exit command, the target diagnostic software immediately initiates multi-tasking, prioritizing network switching. It sends a disconnect command to the target wireless network card, which terminates the diagnostic device's network connection. Subsequently, it automatically reconnects to the external network. Simultaneously, the network switch generates target diagnostic logs, including information such as exit time, device serial number, user account, network switch record, vehicle model, fault code, software upgrade version, and verification results. Finally, the generated target diagnostic logs are uploaded to the target server.

[0063] As described above, this embodiment first determines and verifies the corresponding preset wireless network based on the network connection request to complete the connection. Then, it sends a read command to the target diagnostic device via the diagnostic device's wireless network to obtain its serial number. Subsequently, it shuts down the diagnostic device's wireless network and switches to an external wireless network, verifying user information and the device serial number to obtain access permissions for the target diagnostic software. Finally, in the target diagnostic software, the target network requirements are determined according to the specific diagnostic application scenario, and a suitable target wireless network is selected from the preset wireless networks to perform corresponding preset diagnostic operations on the target vehicle. In this way, by quickly switching network connections, even without an additional external wireless network card, the diagnostic software can automatically handle network changes according to the application scenario, achieving intelligent connection between the network and the device. This not only ensures smooth network verification and data acquisition but also guarantees normal communication with the diagnostic device, reduces manual intervention, simplifies the operation process, and significantly improves the efficiency of diagnostic device applications.

[0064] As can be seen from the previous embodiment, this application discloses a vehicle diagnostic method that can improve the efficiency of diagnostic equipment applications. Next, we will discuss... Figure 4 The vehicle diagnostic methods shown are explained in detail.

[0065] First, this application reads the wireless configuration file in XML format. Based on the network connection requests in this file, the diagnostic tool determines the corresponding preset wireless network, namely the external wireless network and the diagnostic device's wireless network, and verifies the network connection requests, thereby successfully connecting to the preset wireless network.

[0066] Next, using the diagnostic device's wireless network, a device read command is sent to the target diagnostic device. Upon receiving the command, the target diagnostic device returns its serial number, which the diagnostic instrument then obtains.

[0067] Afterwards, the diagnostic device's wireless network will be turned off, and it will switch to an external wireless network. Using this external network, the diagnostic tool will verify the acquired user information and the previously obtained target diagnostic device serial number. Once verification is successful, the diagnostic tool will gain access to the target diagnostic software and can then operate it.

[0068] In the target diagnostic software, the target network requirement is determined based on the actual diagnostic application scenario. For example, in a diagnostic scenario requiring real-time, high-volume data interaction with the vehicle diagnostic module and demanding low latency, the target network requirement is determined to be the diagnostic device's wireless network. In scenarios requiring software upgrades or data uploads that rely on the internet, the target network requirement is the use of an external wireless network. After determining the target network requirement, the diagnostic tool identifies the target wireless network from both the external and diagnostic device wireless networks. Then, using the target wireless network, it performs corresponding preset diagnostic operations on the target vehicle, such as fault code scanning and ECU parameter reading via the diagnostic device's wireless network, or diagnostic software upgrades and diagnostic data uploads via the external wireless network. Simultaneously, the external wireless network can also interact with the internet, providing a channel for the diagnostic software to access a wider range of resources and support.

Finally, within the target diagnostic software, the target network requirements are defined according to the specific diagnostic application scenario, and a suitable target wireless network is selected from the preset wireless networks to perform the corresponding preset diagnostic operations on the target vehicle.
