[0044] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and 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 this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0045] Vehicle diagnostics refers to the process by which after-sales personnel manually troubleshoot any abnormal problems that arise after a vehicle has been sold to a customer. Vehicle diagnostic methods include the following categories:

[0046] (1) Diagnostic instrument diagnosis: This method allows diagnostic equipment to be connected to the vehicle via the On Board Diagnostics (OBD) interface for diagnosis.

[0047] (2) Remote diagnostics with a vehicle communication interface (VCI) device. This method can connect the VCI device to the vehicle's OBD interface, and then the VCI device can be wirelessly connected to a remote diagnostic instrument, mobile device, or computer. Then, the VCI device can be operated remotely to perform diagnostics.

[0048] (3) Basic Remote Diagnostics: A diagnostic control program is integrated into the telematics control unit (T-BOX), which supports a limited set of diagnostic commands. Diagnostic commands are sent directly from the cloud, executed by the diagnostic control program in the vehicle, and the results are returned. Of the three methods above, methods (1) and (2) require offline connection to a diagnostic tool or VCI, and the diagnosis must be performed through the OBD interface, resulting in fewer diagnostic operations. The disadvantage of method (3) is that the number of diagnostic commands that can be accepted is limited and fixed, and cannot be dynamically expanded; and only a single command can be executed at a time, and the result can be received, making it impossible to execute complex logic.

[0049] Specifically, existing basic remote diagnostic methods do not employ script-based diagnostics; instead, they rely on individual commands, which lack logical control functionality. For example, in current technology, when a remote diagnostic platform needs to acquire data, it sends a data acquisition command to the vehicle. The vehicle acquires the data according to this command and returns it to the remote diagnostic platform. The platform then continues subsequent vehicle diagnostics based on the received data. Similarly, when the remote diagnostic platform needs to control the vehicle to perform operations, it sends operation commands to the vehicle, which executes the corresponding operations and provides feedback. Upon receiving the feedback, the remote diagnostic platform continues the subsequent vehicle diagnostic process. In essence, existing remote vehicle diagnostic methods involve the remote diagnostic platform sending commands to the vehicle one by one, with the vehicle executing each command sequentially. The vehicle can only execute a single command at a time and cannot perform complex logic.

[0050] Figure 1 This is a schematic diagram of one application scenario disclosed herein. For example... Figure 1 As shown, the application scenario includes: cloud diagnostic platform 110 and vehicle 120.

[0051] In some implementations, the cloud diagnostic platform 110 may include user-used electronic devices, such as personal computers, mobile phones, tablets, laptops, and e-book readers, which are computer devices with certain computing capabilities. The cloud diagnostic platform 110 may include independent physical servers, server clusters consisting of multiple physical servers, distributed systems, and a Content Delivery Network (CDN) capable of providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, and security services. In this application scenario, one or more components (e.g., the cloud diagnostic platform 110, the vehicle 120) can be connected via any type of wireless network.

[0052] This disclosure proposes a remote vehicle diagnostic method based on a script engine. Figure 2 This is a schematic diagram of the application system structure for remote vehicle diagnostics according to this disclosure. The remote vehicle diagnostics method proposed in this embodiment can be applied to this application system. Figure 2 As shown, this embodiment of the present disclosure can set up a script engine inside the vehicle and set up a cloud diagnostic platform remotely. The script engine receives diagnostic scripts from the cloud diagnostic platform and performs an interactive script execution process, which can expand the diagnostic functions of the vehicle.

[0053] Figure 3 This is a schematic diagram of a vehicle remote diagnostic method according to the present disclosure. Figure 1This method can be applied to the script engine of a vehicle remote diagnostics application system. This script engine can be set up inside the vehicle, such as... Figure 3 As shown, the method may include at least a portion of the following steps:

[0054] S310, Receive diagnostic scripts from the cloud-based diagnostic platform;

[0055] S320. Parse and execute the diagnostic script, and send the execution results to the cloud diagnostic platform during the execution process;

[0056] S330: Receive input information from the cloud-based diagnostic platform, use this input information as input parameters during the execution process, and continue executing the diagnostic script.

[0057] In this way, the script engine can achieve an interactive script execution process. For example, S320 and S330 can be executed repeatedly until the diagnostic script is fully executed. The core of the diagnostic script is its support for logical control functions, including sequential execution, conditional statements, loop statements, and judgment statements. Because the diagnostic script is executed using a script engine, and the diagnostic script supports logical control functions, it avoids the existing method of receiving and executing instructions one by one for vehicle diagnosis, thus improving the efficiency of vehicle diagnosis and saving labor costs. Furthermore, due to the interactive script execution method, input information is received from the cloud diagnostic platform during script execution and used as input parameters in subsequent script execution processes to control the subsequent diagnostic script execution process. Therefore, it can expand the diagnostic functions of the vehicle and achieve better results, improving customer satisfaction.

[0058] In some implementations, the method may further include sending the diagnostic results to the cloud diagnostic platform after the diagnostic script has been executed, so that the cloud diagnostic platform can display the diagnostic results.

[0059] By sending the diagnostic results to the cloud-based diagnostic platform, the platform can display the results, allowing the diagnostic experts to see them clearly and take appropriate action.

[0060] In some implementations, a diagnostic master control program can be set in the vehicle's T-BOX, and a script engine can be set within this program. The Telematics BOX (T-BOX), also known as the in-vehicle T-BOX, is a component of the vehicle-to-everything (V2X) system. The V2X system comprises four parts: the main unit, the in-vehicle T-BOX, a mobile app, and a backend system. The in-vehicle T-BOX can communicate with the backend system / mobile app, enabling vehicle information display and control via the app. Setting the script engine within the diagnostic master control program of the T-BOX facilitates interaction between the diagnostic engine and a remote cloud-based diagnostic platform.

[0061] Figure 4 This is a schematic diagram of another application system architecture for remote vehicle diagnostics disclosed herein. For example... Figure 4 As shown, a diagnostic master control program is installed in the vehicle's T-BOX, and a script engine is installed within the diagnostic master control program. In some implementations, a cloud-based diagnostic platform (hereinafter referred to as the diagnostic platform) is installed remotely, and the cloud-based diagnostic platform and the vehicle can communicate through a secure communication layer. The cloud-based diagnostic platform can include a script editor unit for editing diagnostic scripts for vehicle fault diagnosis and sending the diagnostic scripts to the vehicle. The script engine in the vehicle can receive the diagnostic script, parse it, and execute it; during execution, the script engine can send the execution results to the cloud-based diagnostic platform. After receiving the execution results, the cloud-based diagnostic platform can display them; based on the execution results, diagnostic experts can input information into the cloud-based diagnostic platform to control subsequent execution processes. After receiving the input information from the diagnostic expert, the cloud-based diagnostic platform sends the input information to the vehicle. The script engine in the vehicle receives this input information and uses it as input parameters for subsequent script execution, thereby continuing to execute the diagnostic script.

[0062] In some implementations, embodiments of this disclosure may place the instructions supported by the diagnostic script in a dynamic link library. This dynamic link library may be an SO library or a DLL library, etc. During the execution of the diagnostic script, the instructions supported by the diagnostic script can be called from the dynamic link library at any time and executed. Figure 4 As shown in the embodiments of this disclosure, the instructions involved can be uploaded by diagnostic experts to a cloud-based diagnostic platform, and the cloud-based diagnostic platform can then send the uploaded instructions to the vehicle, where they are stored. For example, diagnostic experts can upload instructions supported by the diagnostic script to the cloud-based diagnostic platform using an SO library upload method; the cloud-based diagnostic platform sends the uploaded instructions to the T-BOX or central gateway in the form of an SO library; the vehicle stores the received instructions in the form of an SO library, and each SO library may include one or more instructions. Figure 4The diagram illustrates a method for uploading, sending, and saving instructions supported by diagnostic scripts in SO format. In other embodiments of this disclosure, other dynamic link libraries can be used for uploading, sending, and saving instructions, such as DLLs. This disclosure does not limit the specific implementation method.

[0063] In some embodiments, the method proposed in this disclosure may further include: receiving instructions supported by the diagnostic script from a cloud-based diagnostic platform; storing the instructions in multiple dynamic link libraries, with each dynamic link library storing one or more instructions.

[0064] By storing the instructions supported by the diagnostic scripts in their respective dynamic link libraries, the diversity of vehicle diagnostic methods can be improved, facilitating dynamic control of vehicle diagnostics.

[0065] In some implementations, the process of parsing and executing the diagnostic script in the method proposed in this disclosure may include:

[0066] Parse the diagnostic script;

[0067] Execute the diagnostic script and, during execution, determine the instructions supported by the diagnostic script.

[0068] Identify and invoke the instructions supported by the diagnostic script from the dynamic link library;

[0069] Execute the commands supported by this diagnostic script.

[0070] Taking dynamic link libraries, including SO libraries, as an example, when a script engine executes a diagnostic script, if the diagnostic script needs to call instruction A, the script engine can find the SO library containing instruction A, retrieve the code of instruction A from the SO library, execute the code of instruction A, and then continue executing the diagnostic script; when the diagnostic script needs to call instruction B, the script engine can find the SO library containing instruction B, retrieve the code of instruction B from the SO library, and execute the code; ... and so on, until the diagnostic script has been executed.

[0071] By calling the necessary instructions in real time during the execution of the diagnostic script, the flexibility of vehicle diagnosis can be improved, thereby enhancing the overall diagnostic effect and increasing user satisfaction.

[0072] In some implementations, the instructions supported by the diagnostic scripts in these embodiments can be updated in real time. For example, a dynamic link library including an SO library, such as... Figure 4As shown, for example, a diagnostic expert sends an instruction operation command to an instruction on a cloud-based diagnostic platform; the instruction operation command can be used to instruct the operation performed on the instructions supported by the diagnostic script, such as instructing at least one of the following operations: extension operation, modification operation, and deletion operation.

[0073] Accordingly, in some implementations, the script engine can receive instruction operation commands from the cloud diagnostic platform; these instruction operation commands are used to indicate the operation to be performed on the instruction; and the dynamic link library corresponding to the instruction can be updated according to the instruction operation commands.

[0074] By receiving instruction operation commands from the cloud-based diagnostic platform and updating the corresponding dynamic link libraries based on these commands, the instructions supported by the diagnostic script can be dynamically updated, facilitating the updating and upgrading of vehicle diagnostic methods.

[0075] This disclosure also proposes another method for remote vehicle diagnostics, which can be applied to a cloud-based diagnostic platform, such as... Figure 4 The diagnostic platform in the vehicle remote diagnostic application system shown is illustrated. Figure 5 As shown, the method may include at least some of the following steps:

[0076] S510. Edit the vehicle's diagnostic script and send the diagnostic script to the script engine, which is set up inside the vehicle.

[0077] S520: Receive the execution results of the diagnostic script during its execution from the script engine;

[0078] S530. Display the execution result and receive the input information based on the execution result;

[0079] S540. Send the input information to the script engine. The input information serves as the input parameter for the diagnostic script during execution.

[0080] In some implementations, the script engine can be set up inside the vehicle, such as in the diagnostic master program in the vehicle's T-BOX.

[0081] The cloud-based diagnostic platform can receive information input from diagnostic experts and use this information to edit vehicle diagnostic scripts. These scripts support logical control functions, including sequential execution, conditional statements, loops, and conditional statements. The cloud-based platform sends the diagnostic script to a script engine, which parses and executes it. Because the script engine executes the diagnostic script, and the script supports logical control functions, it avoids the need to receive and execute instructions line by line, thus improving diagnostic efficiency and saving labor costs. Furthermore, during script execution, the cloud-based platform can receive the execution results in real time and send the expert's input based on these results back to the script engine for further execution. This interactive script execution method allows the cloud-based platform to effectively control the subsequent execution process, expanding vehicle diagnostic capabilities, achieving better results, and increasing customer satisfaction.

[0082] In some implementations, the vehicle diagnostic method may further include a cloud-based diagnostic platform receiving diagnostic results from a script engine and displaying the diagnostic results.

[0083] By displaying the diagnostic results, the results can be presented intuitively to diagnostic experts, who can then take appropriate action based on them.

[0084] In some implementations, the cloud-based diagnostic platform can update and edit the instructions supported by the script in real time and send the instructions supported by the diagnostic script to the script engine. These instructions are stored in multiple dynamic link libraries, with one or more of the instructions stored in each dynamic link library.

[0085] In some implementations, the method further includes sending an instruction operation command to the script engine; the instruction operation command is used to indicate the operation to be performed on the instruction.

[0086] In some implementations, the instruction operation command is used to instruct at least one of the following operations: expansion operation, modification operation, and deletion operation.

[0087] By editing the instructions supported by the diagnostic scripts and sending these instructions to the vehicle, which then stores the instructions in their corresponding dynamic link libraries, the diversity of vehicle diagnostic methods can be improved, facilitating dynamic control of vehicle diagnostics. Furthermore, the cloud-based diagnostic platform can send and receive instruction operation commands to the vehicle, controlling the vehicle to update the corresponding dynamic link libraries based on these commands. This enables dynamic updates to the instructions supported by the diagnostic scripts, facilitating the updating and upgrading of vehicle diagnostic methods.
