[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] Figure 1 This is a flowchart of a vehicle fault detection method provided in an embodiment of this application. This vehicle fault detection method is applied to the vehicle end, such as... Figure 1 As shown, the method includes steps 110 to 130.

[0049] Step 110: Receive the fault detection script sent by the server.

[0050] In an exemplary embodiment, the fault detection script may correspond to the position of the vehicle (such as the front left side of the vehicle, the front right side of the vehicle, etc.), that is, different positions of the vehicle correspond to different fault detection scripts, and the fault detection scripts are used to perform fault detection on the corresponding positions of the vehicle.

[0051] In one exemplary embodiment, after-sales experts can log in to the corresponding application on a mobile terminal such as a mobile phone and select the fault detection script for the corresponding vehicle collision location. The mobile terminal sends the script identifier of the fault detection script to the server. The server obtains the corresponding fault detection script based on the script identifier and sends the fault detection script to the vehicle. The vehicle receives the fault detection script sent by the server.

[0052] Step 120: Execute the fault detection script and perform the target operation during the execution of the fault detection script to obtain the target operation result. The target operation includes vehicle control operation and / or reading target signal value.

[0053] In one exemplary embodiment, after receiving a fault detection script, the vehicle executes the script. The fault detection script may involve performing a target operation. During the execution of the fault detection script, the target operation is performed to perform vehicle control operations and / or read target signal values ​​to obtain the target operation result. For example, when the target operation is a vehicle control operation, the target operation result can be operation success or operation failure; when the target operation is reading a target signal value, the target operation result is the read target signal value. Target signals may include, for example, headlight signals, seat signals, air conditioning signals, power signals, central locking signals, and the vehicle's gear position.

[0054] Step 130: Send the target operation result to the server. The target operation result is used to request the server to perform fault detection analysis to obtain fault detection results.

[0055] Upon receiving the target operation result, the vehicle can feed it back to the server in real time. After the fault detection script completes its execution, the vehicle sends a completion message to the server. The server then performs fault detection analysis on the received target operation result to obtain the final fault detection result. During this analysis, the server can combine the input from after-sales experts regarding vehicle faults with the target operation result to obtain fault detection results, such as identifying damaged components, and generate an analysis report including the fault detection results. The server can employ existing methods based on target operation results for fault detection analysis; this embodiment does not limit the specific method used.

[0056] The vehicle fault detection method provided in this application embodiment receives a fault detection script sent by the server, executes the fault detection result, performs a target operation during the execution of the fault detection script, obtains the target operation result, and sends the target operation result to the server. The server then performs fault detection analysis based on the target operation result to obtain the fault detection result. In this application embodiment, the server can send the fault detection script to the vehicle, and the vehicle can execute the fault detection script and feed back the target operation result during the execution process to the server. The server can determine the fault detection result based on the target operation result. The entire fault detection process does not require connection to a DTC diagnostic tool or manual judgment, thereby reducing detection costs, improving detection efficiency, avoiding errors in manual judgment, and improving detection accuracy.

[0057] Based on the above technical solution, the vehicle end includes a vehicle engine and vehicle applications;

[0058] The execution of the target operation during the execution of the fault detection script may include: during the execution of the fault detection script, sending a target operation execution request to the vehicle application through the vehicle engine; executing the target operation through the vehicle application; and returning the target operation result to the vehicle engine.

[0059] In one exemplary embodiment, the vehicle-side engine, also known as the function computing engine, together with the function computing platform (second server) on the server side, forms an integrated edge-cloud function computing product. It can operate function scripts in the cloud, run them on the vehicle, and provide a calling interface for the server (first server). The vehicle-side engine is deployed on the vehicle side to perform function computing in the background, i.e., to execute fault detection scripts.

[0060] In one exemplary embodiment, a vehicle-side application is an application in the vehicle that can provide services to users and after-sales departments.

[0061] In an exemplary embodiment, the vehicle engine receives a fault detection script sent by the server (second server), brings up the main interface of the vehicle application, and executes the fault detection script in the background of the vehicle. During the execution of the fault detection script, if the fault detection script requires the execution of a target operation, the vehicle engine sends a target operation execution request to the vehicle application. The vehicle application executes the target operation based on the target operation execution request and returns the target operation result to the vehicle engine.

[0062] By coordinating the vehicle-side engine and vehicle-side applications to execute fault detection scripts and target operations, the results of the target operations can be accurately obtained without relying on DTC diagnostic tools, thus reducing equipment costs in the fault detection process.

[0063] Based on the above technical solution, before executing the fault detection script, the method may further include: sending an authentication command to the vehicle application through the vehicle engine; and obtaining authorization through the vehicle application when the user is logged in.

[0064] In one exemplary embodiment, the vehicle-side engine needs to perform authentication before executing the fault detection script. This involves authenticating the user (who could be an after-sales expert) and downgrading vehicle safety permissions. The vehicle-side engine sends an authentication command to the vehicle-side application. Based on the authentication command, the vehicle-side application displays an authorization interface when the user is logged in and obtains the user's authorization through the authorization interface. If the user is not logged in, the vehicle-side application displays a login interface and obtains the user's authorization after the user logs in. At the same time, the vehicle-side application also needs to confirm that the vehicle is in P gear. If the vehicle is not in P gear, it prompts the user to switch the vehicle to P gear. The authentication is confirmed to be successful when the user authorizes and the vehicle is in P gear, and the authentication result is returned to the vehicle-side engine. After receiving the authentication result, the vehicle-side engine can execute the fault detection script.

[0065] By sending authentication commands from the vehicle engine to the vehicle application, and having the vehicle application perform authentication, the fault detection script can be executed when the user authorizes it and the vehicle is in P gear, thus ensuring vehicle safety.

[0066] Based on the above technical solution, the method may further include: after the fault detection script is executed, the vehicle-side engine executes a termination function to send a termination command to the vehicle-side application; and the vehicle-side application controls the vehicle to restore the target state.

[0067] In one exemplary embodiment, the closing function is a script that runs after the fault detection script has finished running, restoring the vehicle to its default state.

[0068] In one exemplary embodiment, after the fault detection script finishes execution, the vehicle-side engine executes a cleanup function and sends a cleanup command to the vehicle-side application. Based on the cleanup command, the vehicle-side application controls the vehicle to restore the target state.

[0069] By controlling the vehicle to return to the target state after the fault detection script finishes execution, the vehicle can be restored to the target state.

[0070] Based on the above technical solution, the method may further include: sending the execution progress of the fault detection script to the server.

[0071] In one exemplary embodiment, during the execution of the fault detection script, the vehicle engine can send the execution progress of the fault detection script to the server, and the server can send the execution progress to the mobile terminal so that the execution progress can be displayed in real time on the mobile terminal, making it easier for after-sales experts to understand the progress of fault detection.

[0072] Figure 2 This is a flowchart of a vehicle fault detection method provided in an embodiment of this application. This vehicle fault detection method is applied to a server, such as... Figure 2 As shown, the method includes steps 210 to 250.

[0073] Step 210: Receive a fault detection request sent by the mobile terminal. The fault detection request includes a script identifier and a vehicle identifier.

[0074] In one exemplary embodiment, the script identifier is an identifier for a fault detection script. The fault detection script may correspond to the vehicle's position (such as the front left side of the vehicle, the front right side of the vehicle, etc.), that is, different positions of the vehicle correspond to different fault detection scripts, and the fault detection scripts are used to perform fault detection at the corresponding positions of the vehicle.

[0075] In one exemplary embodiment, the vehicle identifier is a unique identifier for the vehicle, such as the VIN (Vehicle Identification Number). The VIN is determined by national vehicle management standards and contains information such as the vehicle's manufacturer, year, model, body style and code, engine code, and assembly location. Each vehicle has a unique VIN code.

[0076] In one exemplary embodiment, after-sales experts can log in to the corresponding application on a mobile terminal such as a mobile phone, select the fault detection script for the corresponding vehicle collision location, and input the vehicle identifier of the vehicle to be detected. The mobile terminal sends a fault detection request, including the footprint identifier of the fault detection script and the vehicle identifier, to the server, and the server receives the fault detection request sent by the mobile terminal.

[0077] Step 220: Send the fault detection script corresponding to the script identifier to the vehicle terminal corresponding to the vehicle identifier.

[0078] In one exemplary embodiment, after receiving a fault detection request from a mobile terminal, the server obtains the corresponding fault detection script based on the script identifier in the fault detection request and sends the fault detection script to the vehicle terminal corresponding to the vehicle identifier.

[0079] Step 230: Receive the target operation result sent by the vehicle terminal. The target operation result is the result of the target operation performed by the vehicle terminal during the execution of the fault detection script. The target operation includes vehicle control operation and / or reading target signal value.

[0080] In one exemplary embodiment, after receiving a fault detection script from the server, the vehicle can execute the script and perform a target operation during its execution to obtain the target operation result, which is then sent to the server. For example, when the target operation is a vehicle control operation, the result can be either successful or unsuccessful; when the target operation is reading a target signal value, the result is the read target signal value. Target signals may include, for example, headlight signals, seat signals, air conditioning signals, power signals, central locking signals, and the vehicle's gear position.

[0081] Step 240: Perform fault detection analysis on the target operation result to obtain fault detection results.

[0082] In one exemplary embodiment, after the fault detection script completes execution, the vehicle sends the script completion information to the server. The server performs fault detection analysis on the received target operation results to obtain the final fault detection result. When performing fault detection analysis on the target operation results, the server can combine the input content of after-sales experts regarding vehicle faults with the target operation results to obtain fault detection results, such as identifying damaged components, and generate an analysis report including the fault detection results. The server can perform fault detection analysis using existing methods based on target operation results; this embodiment does not limit this approach. For example, when analyzing the target operation results, the server can compare the target operation results with the corresponding correct operation results to determine whether the target operation performed by the vehicle is faulty. If the target operation is faulty, the server can identify the component associated with the target operation as the faulty component.

[0083] Step 250: Send the fault detection result to the mobile terminal.

[0084] In one exemplary embodiment, the server sends the fault detection results to the mobile terminal, which can then display the results for easy viewing by after-sales experts to help them repair the vehicle.

[0085] The vehicle fault detection method provided in this application embodiment, after receiving a fault detection request sent by a mobile terminal, sends the fault detection script corresponding to the script identifier in the fault detection request to the vehicle terminal corresponding to the vehicle identifier, receives the target operation result sent by the vehicle terminal, the target operation result is the result of the target operation executed during the execution of the fault detection script by the vehicle terminal, performs fault detection analysis on the target operation result to obtain the fault detection result, and sends the fault detection result to the mobile terminal. In this application embodiment, the fault detection script can be sent from the server to the vehicle terminal, and the vehicle terminal can execute the fault detection script and feed back the target operation result during the execution process to the server. The server can determine the fault detection result based on the target operation result. The entire fault detection process does not require connection to a DTC diagnostic tool or manual judgment, thereby reducing detection costs, improving detection efficiency, avoiding errors in manual judgment, and improving detection accuracy.

[0086] Based on the above technical solution, the server includes a first server and a second server;

[0087] Sending the fault detection script corresponding to the script identifier to the vehicle terminal corresponding to the vehicle identifier may include: sending a call request from the first server to the second server, the call request including the script identifier and the vehicle identifier; and sending the fault detection script corresponding to the script identifier to the vehicle terminal corresponding to the vehicle identifier through the second server.

[0088] In one exemplary embodiment, the first server is a data science platform with capabilities such as calling the capabilities of the second server (function computing platform) and analyzing vehicle test data. The first server provides services to applications in the mobile terminal to perform vehicle fault detection.

[0089] In one exemplary embodiment, the second server, also referred to as a function computing platform, is an edge-cloud integrated function computing product that, together with the vehicle-side engine, can operate function scripts (such as fault detection scripts) in the cloud and run them on the vehicle side, providing a calling interface for the server (first server). The second server provides fault detection scripts for different fault types (i.e., vehicle location).

[0090] In an exemplary embodiment, the first server receives a fault detection request sent by the mobile terminal and sends a call request including a script identifier and a vehicle identifier to the second server to call the fault detection script in the second server. After receiving the call request sent by the first server, the second server sends the fault detection script corresponding to the script identifier to the vehicle terminal corresponding to the vehicle identifier.

[0091] By sending a call request from the first server to the second server, the second server sends the fault detection script to the vehicle, thus achieving isolation between the vehicle fault detection service and the script service.

[0092] Based on the above technical solution, the method may further include: sending the target operation result to the mobile terminal, wherein the target operation result is used to display on the mobile terminal.

[0093] In an exemplary embodiment, after receiving the target operation result sent by the vehicle, the server can send the target operation result to the mobile terminal in real time so that the target operation result can be displayed in real time on the mobile terminal, enabling after-sales experts to understand the fault detection information in real time.

[0094] Based on the above technical solution, the method may further include: receiving the execution progress of the fault detection script sent by the vehicle terminal, and sending the execution progress to the mobile terminal, wherein the execution progress is used to display on the mobile terminal.

[0095] In an exemplary embodiment, during the execution of the fault detection script, the vehicle engine can send the execution progress of the fault detection script to the server (first server), and the server can send the execution progress to the mobile terminal to display the execution progress in real time on the mobile terminal, so that after-sales experts can understand the progress of fault detection.

[0096] Figure 3 This is a flowchart of a vehicle fault detection method provided in an embodiment of this application. This vehicle fault detection method is applied to a mobile terminal, such as... Figure 3 As shown, the method includes steps 310 to 330.

[0097] Step 310: Obtain the script identifier and the vehicle identifier of the vehicle to be detected, wherein the script identifier is the identifier of the fault detection script to be executed.

[0098] In one exemplary embodiment, the script identifier is an identifier for a fault detection script. The fault detection script may correspond to the vehicle's position (such as the front left side of the vehicle, the front right side of the vehicle, etc.), that is, different positions of the vehicle correspond to different fault detection scripts, and the fault detection scripts are used to perform fault detection at the corresponding positions of the vehicle.

[0099] In one exemplary embodiment, the vehicle identifier is a unique identifier for the vehicle, such as the VIN (Vehicle Identification Number). The VIN is determined by national vehicle management standards and contains information such as the vehicle's manufacturer, year, model, body style and code, engine code, and assembly location. Each vehicle has a unique VIN code.

[0100] In one exemplary embodiment, an after-sales expert can log into a corresponding application on a mobile terminal such as a smartphone, select a fault detection script for the corresponding vehicle collision location, and input the vehicle identifier of the vehicle to be detected. The mobile terminal obtains the step identifiers of the fault detection script and the vehicle identifier of the vehicle to be detected. The mobile terminal application can directly display the step identifiers of all fault detection scripts for the user to select, or it can recommend corresponding fault detection scripts based on the vehicle information (such as the fault location) input by the after-sales expert.

[0101] Step 320: Send a fault detection request, including the script identifier and the vehicle identifier, to the server.

[0102] In one exemplary embodiment, the mobile terminal sends a fault detection request, including a footstep identifier and a vehicle identifier, comprising a fault detection script, to the server. Upon receiving the fault detection request from the mobile terminal, the server obtains the fault detection script corresponding to the script identifier and sends it to the vehicle terminal corresponding to the vehicle identifier. The vehicle terminal executes the fault detection script, performs a target operation during script execution, obtains the target operation result, and sends the result to the server. After the script execution is complete, the vehicle terminal sends script completion information to the server. The server performs fault detection analysis on the received target operation results to obtain the final fault detection result.

[0103] Step 330: Receive the fault detection result sent by the server and display the fault detection result.

[0104] In one exemplary embodiment, after determining the fault detection result, the server sends the detection result to the mobile terminal, which then receives and displays the fault detection result.

[0105] The vehicle fault detection method provided in this application obtains a script identifier and a vehicle identifier of the vehicle to be tested, sends a fault detection request including the script identifier and the vehicle identifier to a server, receives the fault detection result sent by the server and displays the fault detection result. The server can send the fault detection script corresponding to the script identifier to the vehicle terminal corresponding to the vehicle identifier, and the vehicle terminal executes the fault detection script and feeds back the target operation result during the execution process to the server. The server can determine the fault detection result based on the target operation result. The entire fault detection process does not require connection to a DTC diagnostic instrument or manual judgment, thereby reducing detection costs, improving detection efficiency, avoiding errors in manual judgment, and improving detection accuracy.

[0106] Based on the above technical solution, the method may further include: receiving the target operation result sent by the server and displaying the target operation result, wherein the target operation result is the result of performing the target operation during the execution of the fault detection script by the vehicle, and the target operation includes vehicle control operation and / or reading target signal value.

[0107] In one exemplary embodiment, when the target operation is a vehicle control operation, the result of the target operation can be either successful or unsuccessful; when the target operation is reading a target signal value, the result of the target operation is the read target signal value. Target signals may include, for example, headlight signals, seat signals, air conditioning signals, power signals, central locking signals, and the vehicle's gear position.

[0108] In one exemplary embodiment, after receiving the target operation result sent by the vehicle, the server can send the target operation result to the mobile terminal in real time. The mobile terminal can display the target operation result in real time, so that after-sales experts can understand the fault detection information in real time.

[0109] Based on the above technical solution, the method may further include: receiving the execution progress of the fault detection script sent by the server, and displaying the execution progress.

[0110] In one exemplary embodiment, during the execution of the fault detection script, the vehicle engine can send the execution progress of the fault detection script to the server (first server), and the server can send the execution progress to the mobile terminal. The mobile terminal can display the execution progress in real time, so that after-sales experts can understand the progress of fault detection.

[0111] Figure 4 This is a schematic diagram of the overall processing flow of the vehicle fault detection method in the embodiments of this application, as shown below. Figure 4As shown, when a vehicle malfunctions, after-sales experts can select the appropriate type of fault detection script in the mobile app (mobile terminal application) based on the vehicle's condition and input the vehicle identifier. The mobile app then sends a fault detection request, including the fault detection script identifier and the vehicle identifier, to the first server. The first server calls the function calculation capability of the second server to send the fault detection script corresponding to the script identifier to the vehicle engine. The vehicle engine executes the fault detection script. During the execution of the fault detection script, the script uses dynamic capabilities to notify the vehicle application to perform target operations, such as performing vehicle control operations and / or reading target signal values, and returns the target operation results to the first server (information synchronization). The first server performs fault detection analysis based on the target operation results to determine whether a component is faulty and generates a fault detection report including the fault detection results, which is then sent to the mobile app.

[0112] Figure 5 This is a flowchart of a vehicle fault detection method provided in an embodiment of this application, such as... Figure 5 As shown, the vehicle fault detection method may include a script distribution phase, a test execution phase, and a test completion phase, specifically including the following steps:

[0113] Step 501: The mobile terminal application obtains the script identifier and vehicle identifier.

[0114] After the after-sales expert prepares the vehicle to be inspected and the mobile terminal application, they select the script identifier for the fault detection script in the mobile terminal application and enter the vehicle identifier.

[0115] Step 502: The mobile terminal application sends a fault detection request to the first server.

[0116] Step 503: The first server obtains the script identifier and vehicle identifier.

[0117] Step 504: The first server sends a call request to the second server.

[0118] Step 505: The second server obtains the fault detection script corresponding to the script identifier and sends it to the vehicle engine.

[0119] Step 506: The vehicle engine receives the fault detection script and sends a call-up command to the vehicle application, which then calls up the main interface.

[0120] Step 507: The vehicle engine sends an authentication command to the vehicle application, and the vehicle application performs the authentication.

[0121] Step 508: After authentication is successful, the vehicle-side engine executes the fault detection script and controls the vehicle-side application to perform the target operation.

[0122] Step 509: The first server collects vehicle information (such as the target operation result and execution progress) and displays it in real time in the mobile terminal application.

[0123] Step 510: After the script finishes execution, the vehicle engine sends an exit command to the vehicle application, and the vehicle application exits to the background.

[0124] Step 511: The vehicle engine executes the cleanup function and sends a cleanup command to the vehicle application. The vehicle application then controls the vehicle to restore the target state.

[0125] Step 512: The first server performs fault detection and analysis, and sends the fault detection results to the mobile terminal application.

[0126] Step 513: The mobile terminal application displays the fault detection results.

[0127] Steps 501 to 503 are the script distribution stage, steps 504 to 510 are the test execution stage, and steps 511 to 513 are the test completion stage.
