[0023] The application scenarios involved in the embodiments of this application are described below.

[0024] With the continuous development of technology, vehicle diagnostics has gradually evolved from traditional offline diagnostics to remote diagnostics, providing convenience for people.

[0025] In related technologies, during remote diagnostics, repair personnel connect a remote VCI box to the vehicle and then send a diagnostic request to a cloud diagnostic platform (also known as a cloud diagnostic service platform) via a terminal device. This request includes vehicle information, fault information, and the remote VCI box identifier. Upon receiving the request, the cloud diagnostic platform generates a diagnostic task and assigns it to the diagnostic personnel. This task includes vehicle information, fault information, and the communication address corresponding to the remote VCI box identifier. Upon receiving the task, the diagnostic personnel determine the necessary diagnostic functions based on the vehicle and fault information. They then send diagnostic commands to the corresponding remote VCI box using a remote diagnostic tool to obtain diagnostic data from the vehicle connected to that box. Based on this data, they perform fault analysis to obtain a diagnostic result and finally communicate this result to the repair personnel. However, this remote diagnostic method requires manual execution by the diagnostic personnel, and confirmation communication with the repair personnel is necessary after the diagnostic is completed. This results in high labor costs, long processing times, and low diagnostic efficiency.

[0026] Therefore, this application provides a vehicle diagnostic method applied to a diagnostic system. For example, it can be applied to a cloud diagnostic platform within the diagnostic system. In this method, a terminal device sends a diagnostic request to the cloud diagnostic platform, the request including a target diagnostic function identifier and a target VCI device identifier. Upon receiving the diagnostic request, the cloud diagnostic platform determines a first diagnostic device from one or more diagnostic devices based on the target diagnostic function identifier. Each of these diagnostic devices implements one or more diagnostic functions. Based on the target diagnostic function identifier and the target VCI device identifier, the cloud diagnostic platform diagnoses the target vehicle connected to the target VCI device through the first diagnostic device. By receiving structured diagnostic requests, intelligently matching diagnostic devices, and delegating execution, an efficient and scalable cloud diagnostic platform architecture is constructed. Under this architecture, remote automatic diagnostics are performed by allocating a first diagnostic device based on the diagnostic request, which not only improves diagnostic efficiency but also significantly reduces labor costs and enhances the overall flexibility and maintainability of the diagnostic service.

[0027] The vehicle diagnostic system provided in the embodiments of this application will be described below.

[0028] Figure 1 This is a schematic diagram of the structure of a vehicle diagnostic system provided in an embodiment of this application. See also... Figure 1 The diagnostic system 10 may include a terminal device 101 and a cloud diagnostic platform 102.

[0029] Terminal device 101 can communicate with cloud diagnostic platform 102 via wireless connection.

[0030] Terminal device 101 is used to display a remote diagnostic interface, which includes one or more of the following: a vehicle information input box, a diagnostic function selection area, a VCI device selection area, and a send control. A diagnostic request is created based on one or more configuration items in the remote diagnostic interface, and the diagnostic request is sent to cloud diagnostic platform 102. The diagnostic request may include a target diagnostic function identifier and a target VCI device identifier. For example, terminal device 101 can be a terminal device used by a diagnostic personnel. For example, terminal device 101 can be a mobile phone, smartwatch, or laptop computer, etc., and this application embodiment does not limit this. For example, terminal device 101 can display the remote diagnostic interface in a mini-program, application, or public account, and this application embodiment does not limit this.

[0031] In some implementations, the target VCI device can be connected to the target vehicle before the remote diagnostic interface is displayed on the terminal device 101. For example, the target VCI device can be connected to the on-board diagnostics (OBD) interface of the target vehicle. For example, the OBD interface of the target vehicle can be OBD II, etc., and this application embodiment does not limit this.

[0032] The cloud diagnostic platform 102 is used to receive diagnostic requests sent by the terminal device 101, determine a first diagnostic device from one or more diagnostic devices based on a target diagnostic function identifier, each of the one or more diagnostic devices is used to implement one or more diagnostic functions; and perform diagnostics on the target vehicle connected to the target VCI device through the first diagnostic device based on the target diagnostic function identifier and the target VCI device identifier.

[0033] The one or more diagnostic devices are diagnostic devices in the diagnostic system 10. Any one of the one or more diagnostic devices is used to receive diagnostic tasks sent by the cloud diagnostic platform 102, and send diagnostic instructions to the target VCI device based on the communication address and target diagnostic function identifier of the target VCI device, so as to perform diagnostics on the vehicle connected to the target VCI device.

[0034] The one or more diagnostic devices can be pre-installed. For example, the one or more diagnostic devices can be installed in different regions or in the same region; this application embodiment does not limit this. Optionally, the one or more diagnostic devices can be devices for diagnosing the same vehicle model, or the one or more diagnostic devices can be devices for diagnosing different vehicle models. Optionally, each of the one or more diagnostic devices is used to implement one or more diagnostic functions.

[0035] The first diagnostic device is a diagnostic device used to achieve the target diagnostic function.

[0036] The target VCI device can be a VCI device connected to the target vehicle, or a VCI device that communicates with the first diagnostic device. The target VCI device is used to receive diagnostic commands sent by the first diagnostic device, obtain target diagnostic data from the target vehicle connected to the target VCI device based on the diagnostic commands, and send the target diagnostic data to the first diagnostic device.

[0037] The target VCI device can connect to a network. For example, the target VCI device can connect to the network via Wi-Fi, 4G, 5G, or a wired network. Optionally, after connecting to the network, the target VCI device can establish a communication connection with the cloud diagnostic platform 102 and send its VCI device identifier to the cloud diagnostic platform 102. In this way, the cloud diagnostic platform 102 can know the communication address of each VCI device.

[0038] Optionally, the first diagnostic device receives target diagnostic data sent by the target VCI device, analyzes the target diagnostic data, and obtains the diagnostic results of the target vehicle.

[0039] Optionally, after obtaining the diagnostic results of the target vehicle, the first diagnostic device can generate a diagnostic report based on the diagnostic results of the target vehicle and send the diagnostic report to the cloud diagnostic platform 102.

[0040] Optionally, the cloud diagnostic platform 102 receives the diagnostic report sent by the first diagnostic device and sends the diagnostic report to the terminal device 101.

[0041] The vehicle diagnostic method provided in the embodiments of this application will be explained in detail below.

[0042] Figure 2 This is a flowchart of a vehicle diagnostic method provided in an embodiment of this application. Optionally, this method can be applied to the above-described... Figure 1 Diagnostic system 10 in the embodiment. See also Figure 2 The method may include the following steps: Step 201: The terminal device sends a diagnostic request to the cloud diagnostic platform. The diagnostic request includes the target diagnostic function identifier and the target VCI device identifier.

[0043] The target diagnostic function identifier is the identifier of the diagnostic function that requires remote diagnosis.

[0044] The target VCI device is identified as the VCI device that requires remote diagnostics.

[0045] The terminal device sends a diagnostic request, including a target diagnostic function identifier and a target VCI device identifier, to the cloud diagnostic platform, thereby providing data for the cloud diagnostic platform to subsequently determine the first diagnostic device and for the first diagnostic device to communicate with the target VCI device identified by the target VCI device identifier to diagnose the vehicle.

[0046] In some implementations, before the terminal device sends a diagnostic request to the cloud diagnostic platform, the user can configure the configuration information required for the diagnostic request in the terminal device. The configuration process may include the following steps (1) to (4).

[0047] Step (1): The terminal device displays a remote diagnostic interface, which includes a vehicle information input area, a diagnostic function selection area, a VCI device selection area, and a send control. The VCI device selection area displays one or more VCI device options.

[0048] This vehicle information input box is used to enter the identifier of the target vehicle. For example, the target vehicle identifier can be a vehicle identification number (VIN), etc.

[0049] The diagnostic function selection area is the area for selecting the diagnostic function corresponding to the target vehicle identifier. Optionally, after responding to an input operation applied to the vehicle information input box, the terminal device 101 can obtain one or more diagnostic function options corresponding to the input target vehicle identifier, and then display the one or more diagnostic function options in the diagnostic function selection area.

[0050] The VCI device selection area is the area for selecting VCI devices (also known as remote VCI boxes). For example, one or more VCI devices displayed in this VCI device selection area can be devices bound to terminal device 101, specifically devices bound to user accounts logged in on terminal device 101.

[0051] Step (2): The terminal device responds to the input operation applied to the vehicle information input area and obtains the input target vehicle identifier.

[0052] For example, the input operation can be a manual input operation, a voice input operation, etc., and this application embodiment does not limit it.

[0053] Step (3): The terminal device displays one or more diagnostic function options corresponding to the target vehicle identifier in the diagnostic function selection area; in response to the selection operation of any one of the diagnostic function options, the target diagnostic function identifier corresponding to the selected diagnostic function option is obtained.

[0054] The one or more diagnostic function options are options for diagnosing the functions of the target vehicle identified by the target vehicle identifier.

[0055] There is a correspondence between the target vehicle identifier and one or more diagnostic function options. This correspondence can be preset. For example, it can be set by a technician based on the diagnostic functions available on the diagnostic equipment corresponding to the target vehicle.

[0056] The target diagnostic function identifier is the identifier of the target diagnostic function corresponding to the selected diagnostic function option.

[0057] By displaying one or more diagnostic function options, users can clearly see all the diagnostic functions that the target vehicle has, providing them with options to select diagnostic functions and thus improving the accuracy of function selection. On the other hand, by selecting a specific diagnostic function, a basis can be provided for subsequently determining the primary diagnostic device.

[0058] Step (4): In response to the selection operation of any VCI device option in the VCI device selection area, the terminal device obtains the target VCI device identifier corresponding to the selected VCI device option. The target VCI device identified by the target VCI device identifier is used to connect with the target vehicle identified by the target vehicle identifier.

[0059] By selecting the VCI device option, data is provided for establishing a communication connection between the primary diagnostic device and the target VCI device, ensuring the stable progress of the diagnostic process.

[0060] By displaying a remote diagnostic interface, dynamically linking information, and providing guided operations, the system significantly reduces the difficulty of user operation, improves the accuracy and completeness of requests, provides high-quality input for subsequent cloud processing, and enhances the system's usability and user satisfaction.

[0061] In some implementations, the operation of the terminal device sending a diagnostic request to the cloud diagnostic platform can be: the terminal device sends the diagnostic request to the cloud diagnostic platform in response to an operation performed on the sending control.

[0062] Step 202: After receiving the diagnostic request, the cloud diagnostic platform determines the first diagnostic device from the one or more diagnostic devices based on the target diagnostic function identifier. Each of the one or more diagnostic devices is used to implement one or more diagnostic functions.

[0063] The first diagnostic device is a diagnostic device capable of performing the target diagnostic function in the diagnostic request, and is also a diagnostic device that will perform the target diagnostic function.

[0064] Identifying the first diagnostic device by using the target diagnostic function identifier can prevent situations where the first diagnostic device cannot perform the target diagnostic function, ensuring that the first diagnostic device can perform the target diagnostic function normally, thereby improving the accuracy and correctness of the diagnosis.

[0065] In some implementations, step 202 may be performed as follows: the cloud diagnostic platform determines whether a target diagnostic function identifier exists in a preset diagnostic function set, the preset diagnostic function set including one or more diagnostic function identifiers; if a target diagnostic function identifier exists in the preset diagnostic function set, one or more second diagnostic devices are determined, each of the one or more second diagnostic devices being used to implement the target diagnostic function; and a first diagnostic device is determined from the one or more second diagnostic devices.

[0066] The preset diagnostic function set is the set of diagnostic functions that one or more diagnostic devices can perform. The preset diagnostic function set can be set in advance.

[0067] The one or more second diagnostic devices are diagnostic devices capable of performing the target diagnostic function.

[0068] If a target diagnostic function identifier exists in the preset diagnostic function set, it means that one or more diagnostic devices exist that can perform the target diagnostic function, i.e., a diagnostic device capable of diagnosing the target vehicle. Therefore, one or more second diagnostic devices can be identified, and then a first diagnostic device that performs the target diagnostic function can be determined from among these one or more second diagnostic devices. If a target diagnostic function identifier does not exist in the preset diagnostic function set, it means that one or more diagnostic devices do not exist that can perform the target diagnostic function, i.e., a diagnostic device capable of diagnosing the target vehicle. Therefore, it is not necessary to identify one or more second diagnostic devices.

[0069] Optionally, if the target diagnostic function identifier is not found in the preset diagnostic function set, the cloud diagnostic platform can send the diagnostic request to the account corresponding to the diagnostic personnel to instruct the diagnostic personnel to perform diagnostics on the target vehicle.

[0070] Optionally, the cloud diagnostic platform may determine the first diagnostic device from the one or more second diagnostic devices by: obtaining device information of each of the one or more second diagnostic devices; and determining the first diagnostic device from the one or more second diagnostic devices based on the device information of each of the one or more second diagnostic devices.

[0071] The equipment information of the second diagnostic device can reflect information such as the operating status of the second diagnostic device. Based on the equipment information of each of the one or more second diagnostic devices, the diagnostic device (i.e. the first diagnostic device) that can quickly perform the target diagnostic task can be determined from the one or more second diagnostic devices.

[0072] In this way, load balancing of one or more second diagnostic devices can be achieved, avoiding device overload or idleness and improving the overall system throughput.

[0073] Optionally, the device information includes device status and task start time. The cloud diagnostic platform determines the first diagnostic device from the one or more second diagnostic devices based on the device information of each of the one or more second diagnostic devices. This operation can be as follows: if there is at least one second diagnostic device in an idle state among the one or more second diagnostic devices, the first diagnostic device is determined from the at least one second diagnostic device; if the device status of all one or more second diagnostic devices is in a working state, the second diagnostic device with the earliest task start time among the one or more second diagnostic devices is determined as the first diagnostic device.

[0074] This device status is used to indicate whether the second diagnostic device is working.

[0075] The start time of this task reflects when the second diagnostic device begins executing the task. The earlier the start time, the earlier the second diagnostic device begins executing the task, and thus the earlier it completes the task; conversely, the later the start time, the later the second diagnostic device begins executing the task, and thus the later it completes the task.

[0076] If at least one of the one or more second diagnostic devices is in an idle state, it means that there is an idle diagnostic device among the one or more second diagnostic devices, that is, there is a diagnostic device among the one or more second diagnostic devices that can immediately perform a task. Therefore, the first diagnostic device can be determined from the at least one second diagnostic device.

[0077] If all of the one or more second diagnostic devices are in a working state, it means that all of the one or more second diagnostic devices are currently working. In other words, there is no diagnostic device among the one or more second diagnostic devices that can immediately execute the task. Therefore, the second diagnostic device with the earliest task start time among the one or more second diagnostic devices can be identified as the first diagnostic device so that the diagnostic device can start executing the task as early as possible.

[0078] In this way, on the one hand, the diagnostic startup time can be minimized, avoiding excessive waiting for users and thus improving user experience. On the other hand, it ensures that the system can still guarantee the orderly progress of tasks even when there is a large workload, significantly improving the system's concurrent processing capabilities and service quality, and reducing task queuing delays.

[0079] In some implementations, the cloud diagnostic platform may determine the first diagnostic device from the at least one second diagnostic device by: determining the second diagnostic device that is closest to the target VCI device among the at least one second diagnostic devices as the first diagnostic device; or, determining the second diagnostic device with the best performance among the at least one second diagnostic devices as the first diagnostic device.

[0080] Since one or more diagnostic devices can be deployed in different regions, in this case, the communication latency of the second diagnostic device farther away from the target VCI device is greater, while the communication latency of the second diagnostic device closer to the target VCI device is smaller, which affects diagnostic efficiency. Therefore, the cloud diagnostic platform can identify the second diagnostic device closest to the target VCI device among the at least one second diagnostic device as the first diagnostic device, thus ensuring diagnostic efficiency.

[0081] The performance of the secondary diagnostic equipment reflects its efficiency in processing tasks. Better performance results in higher efficiency, while poorer performance leads to lower efficiency.

[0082] In this way, the first diagnostic device is selected to perform diagnostic tasks as efficiently as possible, thereby ensuring diagnostic efficiency.

[0083] Step 203: Based on the target diagnostic function identifier and the target VCI device identifier, the cloud diagnostic platform performs diagnostics on the target vehicle connected to the target VCI device through the first diagnostic device.

[0084] Since the target diagnostic function identifier clearly indicates the function that needs to be diagnosed, and the target VCI device identifier can identify the target VCI device that needs to be communicated, the first diagnostic device can communicate with the target VCI device to diagnose the target vehicle connected to the target VCI device.

[0085] By using the cloud platform as the coordination center and diagnostic equipment as the execution end, a "cloud-edge" collaborative architecture is formed, achieving a combination of remote centralized management and distributed execution. Furthermore, on the one hand, transforming tasks that originally required manual remote diagnostics into automated remote diagnostics by diagnostic equipment can significantly improve diagnostic efficiency; on the other hand, because the diagnostic equipment remotely and automatically diagnoses the target vehicle, labor costs can be greatly reduced.

[0086] In some implementations, the cloud diagnostic platform, based on the target diagnostic function identifier and the target VCI device identifier, performs the following steps (1) to (2) by using a first diagnostic device to diagnose the target vehicle connected to the target VCI device.

[0087] Step (1): The cloud diagnostic platform obtains the communication address of the target VCI device based on the target VCI device identifier; and sends a diagnostic task to the first diagnostic device, which includes the target diagnostic function identifier and the communication address of the target VCI device.

[0088] For example, the communication address of the target VCI device can be obtained by the cloud diagnostic platform when communicating with the target VCI device.

[0089] By obtaining the communication address of the target VCI device, a basis is provided for the first diagnostic device to communicate with the target VCI device.

[0090] Step (2): After receiving the diagnostic task, the first diagnostic device performs the target diagnostic function on the target vehicle connected to the target VCI device based on the target diagnostic function identifier and the communication address of the target VCI device.

[0091] By using the target VCI device's communication address, the first diagnostic device can accurately communicate with the target VCI device, thereby performing target diagnostic functions on the target vehicle through the target VCI device. Furthermore, this method achieves end-to-end operability for remote diagnostics, reduces the complexity of direct platform control over diagnostic devices, and ensures the secure and reliable transmission of diagnostic commands, thus enhancing the system's flexibility and security.

[0092] In some implementations, the first diagnostic device performs the target diagnostic function operation on the target vehicle connected to the target VCI device based on the target diagnostic function identifier and the communication address of the target VCI device, and the operation can be performed in the following steps (1) to (3).

[0093] Step (1): The first diagnostic device establishes a communication connection with the target VCI device based on the communication address of the target VCI device; if the communication connection is successfully established, the first diagnostic device sends a diagnostic command to the target VCI device based on the target diagnostic function identifier.

[0094] Due to firewalls, weak networks, or other reasons, the first diagnostic device may fail to establish a communication connection with the target VCI device. Therefore, after ensuring that the communication connection is successfully established, diagnostic commands are sent to the target VCI device based on the target diagnostic function identifier. This can ensure the stable progress of the diagnostic process and improve diagnostic efficiency.

[0095] If the communication connection is successfully established, it indicates that the communication between the first diagnostic device and the target VCI device is normal. The first diagnostic device can communicate normally with the target VCI device, meaning the target VCI device can normally receive diagnostic commands sent by the first diagnostic device. If the communication connection fails to be established, it indicates that the communication between the first diagnostic device and the target VCI device is abnormal. The first diagnostic device cannot communicate with the target VCI device, meaning the target VCI device cannot receive diagnostic commands sent by the first diagnostic device and therefore cannot perform diagnostics on the target vehicle.

[0096] In some implementations, if the communication connection fails to be established, the first diagnostic device can send a communication connection establishment failure message to the cloud diagnostic platform. After receiving the communication connection establishment failure message, the diagnostic platform can allocate a target relay server to the first diagnostic device and the target VCI device based on the diagnostic message, so that the first diagnostic device and the target VCI device can communicate indirectly through the target relay server.

[0097] This method ensures the smooth operation of the diagnostic process.

[0098] Step (2): After receiving the diagnostic command, the target VCI device obtains the target diagnostic data from the connected target vehicle and sends the target diagnostic data to the first diagnostic device.

[0099] The target diagnostic data is vehicle data related to this diagnostic command.

[0100] For example, after receiving the diagnostic command, the target VCI device can convert it into a signal recognizable by the target vehicle and then send the signal to the target vehicle. Upon receiving the signal, the target vehicle can send target diagnostic data to the target VCI device. For example, the target VCI device can convert the diagnostic command into a signal corresponding to a communication protocol such as Controller Area Network (CAN), Line, or Diagnostics Over Internet Protocol (DoIP).

[0101] Step (3): After receiving the target diagnostic data, the first diagnostic device analyzes the target diagnostic data and obtains the diagnostic results.

[0102] Target diagnostic data can reflect the actual operating status of the target vehicle. Therefore, by analyzing the target vehicle data, we can know the current operating status of the target vehicle.

[0103] In some implementations, the first diagnostic device diagnoses the target vehicle connected to the target VCI device based on the target diagnostic function identifier and the target VCI device identifier. After the first diagnostic device generates a diagnostic report based on the diagnostic results of the target vehicle, it sends the diagnostic report to the cloud diagnostic platform. After receiving the diagnostic report, the cloud diagnostic platform sends the diagnostic report to the terminal device.

[0104] This approach creates a complete closed loop from diagnostic execution to user receipt of the diagnostic report, allowing users to access diagnostic conclusions promptly and intuitively. This enhances the user's diagnostic experience.

[0105] To facilitate understanding, the following will be combined with... Figure 3 The vehicle diagnostic method provided in the embodiments of this application will be described by way of example.

[0106] Figure 3 This is a flowchart of the vehicle diagnostic method provided in the embodiments of this application. Figure 3 As shown, this vehicle diagnostic method is applied to a diagnostic system. The diagnostic system includes terminal equipment, a cloud diagnostic platform, N diagnostic devices, and a target VCI device, where N is a positive integer.

[0107] The user connects the target VCI device to the OBD II interface of the target vehicle.

[0108] Afterwards, the user opens the terminal device, configures the diagnostic request option in the remote diagnostic interface, and then controls the terminal device to send the diagnostic request to the cloud diagnostic platform. The diagnostic request includes the target diagnostic function identifier and the target VCI device identifier.

[0109] Upon receiving the diagnostic request, the cloud diagnostic platform determines whether the target diagnostic function identifier exists in the preset diagnostic function set. If the target diagnostic function identifier does not exist in the preset diagnostic function set, the cloud diagnostic platform sends the diagnostic request to a diagnostician for manual diagnosis. If the target diagnostic function identifier exists in the preset diagnostic function set, the cloud diagnostic platform determines a first diagnostic device from N diagnostic devices based on the target diagnostic function identifier. The cloud diagnostic platform then sends a diagnostic task to the first diagnostic device, which includes the target diagnostic function identifier and the communication address of the target VCI device.

[0110] After receiving the diagnostic task, the first diagnostic device sends a diagnostic instruction corresponding to the target diagnostic function identifier to the target VCI device based on the target VCI device's communication address.

[0111] After receiving the diagnostic command, the target VCI device obtains the target diagnostic data from the target vehicle and then sends the target diagnostic data to the first diagnostic device.

[0112] After receiving the target diagnostic data, the first diagnostic device analyzes the target diagnostic data to obtain the diagnostic results; based on the diagnostic results, it generates a diagnostic report and sends the diagnostic report to the cloud diagnostic platform.

[0113] After receiving the diagnostic report, the cloud diagnostic platform sends the diagnostic report to the terminal device.

[0114] In this embodiment, the terminal device sends a diagnostic request to the cloud diagnostic platform. This request includes a target diagnostic function identifier and a target VCI device identifier. Upon receiving the request, the cloud diagnostic platform determines a first diagnostic device from one or more diagnostic devices based on the target diagnostic function identifier. Each of these devices implements one or more diagnostic functions. The cloud diagnostic platform then diagnoses the target vehicle connected to the target VCI device using the first diagnostic device, based on the target diagnostic function identifier and the target VCI device identifier. By receiving structured diagnostic requests, intelligently matching diagnostic devices, and delegating execution, a highly efficient and scalable cloud diagnostic platform architecture is constructed. Under this architecture, remote automatic diagnostics are performed by allocating a first diagnostic device based on the diagnostic request, which not only improves diagnostic efficiency but also significantly reduces labor costs and enhances the overall flexibility and maintainability of the diagnostic service.
