Detailed ways

In order to enable those in the technical field to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

In view of the technical problems raised by the background art, the inventor proposed a remote diagnosis method, device, electronic equipment and storage medium for a vehicle. The corresponding diagnosis script is obtained according to the target diagnosis service actually required by the vehicle end, and is controlled through the central domain. The device parses the diagnostic script and forwards the parsed diagnostic instructions to the electronic control unit, so that the electronic control unit performs diagnostic operations according to the diagnostic instructions and feeds back the diagnostic results. Obtaining the corresponding diagnostic script according to the target diagnosis service of the vehicle terminal realizes the flexible configuration of the diagnostic script and avoids the situation of single fixed script diagnosis task. Moreover, diagnosis through the diagnostic script corresponding to the target diagnosis service can more accurately diagnose the vehicle terminal. The actual fault status is diagnosed, which improves the accuracy of fault diagnosis.

Please refer to FIG. 1 , which shows a schematic flowchart of a vehicle remote diagnosis method provided by an embodiment of the present application. In a specific embodiment, the vehicle remote diagnosis method is applied to the vehicle remote diagnosis device 300 as shown in FIG. 6 and the electronic device 100 configured with the vehicle remote diagnosis device 300 .

The process shown in Figure 1 will be described in detail below. The vehicle remote diagnosis method may specifically include the following steps:

Step S110: The vehicle terminal obtains the diagnosis script corresponding to the target diagnosis service from the cloud.

The diagnostic service refers to diagnosing one or more services of the vehicle in the current state or preset state of the vehicle to determine whether the service is normal. Diagnostic services include but are not limited to battery diagnostic services, driving diagnostic services, etc.

A diagnostic script refers to an executable file written in one or more assembly languages to perform the diagnostic service. Assembly language includes but is not limited to Java, C# and other assembly languages. The selection of assembly language is not specifically limited here.

The vehicle terminal obtains from the cloud the diagnostic script corresponding to the target diagnostic service that the vehicle terminal needs to perform business diagnosis, and uses the diagnostic script to determine whether the target diagnostic service is normal.

Step S120: The central domain controller of the vehicle parses the diagnostic script and obtains the diagnostic instructions.

Diagnostic instructions refer to instructions that need to instruct the processor or other modules to perform work during the diagnostic process.

The central domain controller integrates multiple processors, memories, communication interfaces and other components to achieve fast response and efficient control of vehicle systems.

The central domain controller parses the diagnostic script obtained from the cloud, thereby extracting multiple corresponding diagnostic instructions in the diagnostic script.

Please refer to Figure 2. In some implementations, step S120 includes steps S121 to S125. The details are as follows:

Step S121: The central domain controller of the vehicle obtains the diagnostic information corresponding to the target diagnostic service from the cloud.

Diagnostic information refers to diagnostic information containing diagnostic scripts sent to the vehicle by the cloud in response to the target diagnostic service. The diagnostic information may be transmitted using the Message Queuing Telemetry Transport Protocol (Message Queuing Telemetry Transport, MQTT) or the Hypertext Transfer Protocol (Hypertext Transfer Protocol, HTTP). In the embodiment of this application, the communication protocol is preferably the MQTT protocol, and the diagnostic information is sent by the MQTT server. When data is transmitted using the MQTT protocol, the data transmitted by the MQTT protocol includes header data and payload. The header data is used to represent the basic information of the data, such as data type and other information. The payload is the transmitted data content, in which diagnostic information exists in the payload.

Specifically, according to the determination operation of the target diagnosis service, the subject information carrying the diagnosis script is obtained from the cloud, and the diagnosis information in the subject information is obtained.

The determination operation may be the user's selection and determination operation of the target diagnosis service on the terminal, or it may refer to the user's input operation of the target diagnosis service. The determination operation is not specifically limited here.

Topic information refers to the information corresponding to the payload during the MQTT protocol transmission process, for example, the topic of diagnosing battery power.

According to the determination operation for the target diagnostic business, the topic information carrying the diagnostic script sent from the cloud is obtained through the MQTT protocol, and then further information is extracted from the topic information to obtain the diagnostic information.

Step S122: Extract execution conditions corresponding to the diagnostic script in the diagnostic information.

According to the extraction device or extraction program, the execution conditions corresponding to the diagnostic script are extracted from the diagnostic information. In the embodiment of the present application, the virtual diagnostic instrument in the central domain controller extracts the execution conditions in the diagnostic information. Execution conditions refer to the vehicle condition conditions required to execute the diagnostic script. For example, to execute the diagnostic battery power script, the vehicle needs to be in working condition. The vehicle is in working status as the execution condition for executing the diagnostic battery power script.

Step S123: Obtain the current vehicle condition of the vehicle terminal, and determine whether the current vehicle condition meets the execution condition.

Execution conditions include but are not limited to vehicle speed conditions, power battery power conditions, driving mode conditions, usage mode conditions and other execution conditions. The vehicle speed condition refers to whether the current vehicle speed is higher or lower than a preset vehicle speed. For example, when the vehicle speed is greater than 120km/h, the vehicle stability service is diagnosed. At this time, the vehicle speed condition is greater than 120km/h. The execution conditions can be set according to different diagnostic services and are not specifically limited here.

Step S124: If the execution condition is met, obtain script execution instructions from the diagnostic information.

Compare the current vehicle condition of the vehicle terminal with the execution conditions to determine whether the vehicle terminal under the current vehicle condition meets the execution conditions. For example, the vehicle speed condition in the execution condition is 80km/h and the power battery power is greater than 80%. In the current vehicle condition, the vehicle speed is 80km/h and the power battery power is 85%. At this time, the execution conditions are met, and the running instructions of the diagnostic script are obtained from the diagnostic information to run the diagnostic script. When the vehicle speed does not meet the execution conditions, the vehicle needs to feedback the unsatisfied situation to the cloud to obtain the next step operation instructions from the cloud.

Step S125: Run the diagnostic script according to the script running instruction to obtain the diagnostic instructions in the diagnostic script.

When the current vehicle condition meets the execution conditions and the script running instructions in the diagnostic information are obtained, the script is run according to the script running instructions, and the diagnostic instructions in the post-run diagnostic script are obtained.

Step S130: The central domain controller of the vehicle forwards the diagnosis instruction to the electronic control unit corresponding to the diagnosis instruction.

The electronic control unit is used to convert the received input information into control signals and perform corresponding actions based on the control signals. Different diagnostic instructions require different electronic control units to execute.

Specifically, the central domain controller on the vehicle side analyzes the diagnostic instruction through the diagnostic routing module and obtains the address corresponding to the diagnostic instruction. Obtain the electronic control unit corresponding to the address. The diagnostic routing module is used to forward the diagnostic instructions to the electronic control unit. The diagnostic routing module is mainly used for data forwarding based on the destination address.

The address may be the physical address of the electronic control unit in the vehicle system. Diagnostic instructions include source addresses and destination addresses.

The diagnostic routing module is used to obtain the target address in the diagnostic command, and then the target address is matched to the electronic control unit corresponding to the diagnostic command, and the diagnostic command is forwarded to the electronic control unit through the diagnostic routing module, so that the electronic control unit obtains and Execute diagnostic instructions.

Step S140: The electronic control unit on the vehicle side executes the diagnosis task corresponding to the diagnosis instruction and returns the diagnosis result.

The electronic control unit performs the diagnosis of the diagnosis task according to the diagnosis instruction, obtains the corresponding diagnosis result, and feeds back the diagnosis result to the terminal.

The solution provided by this application obtains the corresponding diagnostic script based on the target diagnostic service actually required by the vehicle end, parses the diagnostic script through the central domain controller, and forwards the parsed diagnostic instructions to the electronic control unit to Make the electronic control unit perform diagnostic operations according to the diagnostic instructions and feed back the diagnostic results. Obtaining the corresponding diagnostic script according to the target diagnosis service of the vehicle terminal realizes the flexible configuration of the diagnostic script and avoids the situation of single fixed script diagnosis task. Moreover, diagnosis through the diagnostic script corresponding to the target diagnosis service can more accurately diagnose the vehicle terminal. The actual fault status is diagnosed, which improves the accuracy of fault diagnosis.

Please refer to FIG. 3 , which shows a schematic flowchart of a vehicle remote diagnosis method provided by an embodiment of the present application. The vehicle remote diagnosis method is applied to the vehicle remote diagnosis device 400 shown in FIG. 7 and the electronic device 100 configured with the vehicle remote diagnosis device 400 . The process shown in Figure 3 will be described in detail below. The vehicle remote diagnosis method may specifically include the following steps:

Step S210: The cloud responds to the target diagnostic service for the vehicle sent by the terminal, and determines the diagnostic script corresponding to the target diagnostic service.

The terminal may be a device with a selection function to facilitate users to select target diagnostic services. The terminal sends the target diagnostic service determined by the user to the cloud, thereby obtaining the diagnostic script corresponding to the target diagnostic service from the cloud.

Please refer to Figure 4. In some implementations, step S210 includes steps S211 to S213, which are described in detail as follows:

Step S211: The information security server in the cloud obtains the written diagnostic script.

The information security server uses public keys and/or private keys for identity authentication.

Specifically, the diagnostic script is based on the writing operation of diagnostic scripts corresponding to different diagnostic services, and the cloud script editing platform obtains the written diagnostic script.

The script editing platform can be a script editing tool. After engineers use the script editing platform to edit different diagnostic scripts, they can be directly synchronized to the cloud to facilitate the use of other engineers and diagnostic services.

Step S212: The information security server in the cloud performs signature authentication on the written diagnostic script.

The information security server performs signature authentication on diagnostic scripts obtained from the cloud to avoid obtaining data containing viruses, which may lead to information security issues such as information loss.

Step S213: Synchronize the signature-authenticated diagnostic script to the diagnostic cloud platform in the cloud.

After the signature is authenticated and determined to be a diagnostic script obtained from the cloud scripting platform, the authenticated diagnostic script is synchronized to the diagnostic cloud platform, and the diagnostic cloud platform implements the issuance of the script.

In other implementations, the script editing platform in the cloud synchronizes the written diagnostic script to the diagnostic cloud platform in the cloud.

The script editing platform can directly synchronize the written scripts to the diagnostic cloud platform in the cloud, saving information security server certification time and improving script synchronization efficiency.

Step S220: Obtain the vehicle identification code corresponding to the vehicle terminal.

The Vehicle Identification Number (VIN) is a seventeen-digit character determined in accordance with the national vehicle management standards and contains information such as the vehicle's manufacturer, age, model, body type and code, engine code, and assembly location. The vehicle identification code can be obtained by direct input by the user, or the terminal and the vehicle terminal can be bound during use, so that the vehicle identification code can be obtained directly from the terminal. The method of obtaining the vehicle identification code is not described here. Specific limitations.

The purpose of obtaining the vehicle identification code is to identify the vehicle terminal and avoid sending diagnostic scripts to other vehicle terminals.

Step S230: The diagnostic cloud platform in the cloud sends the diagnostic script to the vehicle terminal corresponding to the vehicle identification code.

The diagnostic cloud platform identifies the vehicle terminal that needs to perform the target diagnostic service based on the vehicle identification code, and sends the diagnostic script corresponding to the target diagnostic service to the vehicle terminal.

In the embodiment of this application, the cloud sends the diagnostic script corresponding to the target diagnostic service to the vehicle terminal corresponding to the vehicle identification code based on the target diagnostic service and vehicle identification code sent by the terminal, so that the vehicle terminal runs the diagnostic script to perform the diagnostic task, and performs the target diagnosis according to the target diagnosis service. The business sends corresponding diagnostic scripts, which avoids the single diagnostic service caused by fixed diagnostic scripts. Moreover, data transmission based on the vehicle identification code can improve the accuracy of data transmission.

Please refer to FIG. 5 , which shows a schematic diagram of information interaction of a vehicle remote diagnosis method provided by an embodiment of the present application.

Step S310: The cloud responds to the target diagnostic service for the vehicle sent by the terminal, and determines the diagnostic script corresponding to the target diagnostic service.

Step S320: Obtain the vehicle identification code corresponding to the vehicle terminal.

Step S330: The diagnostic cloud platform in the cloud sends the diagnostic script to the vehicle terminal corresponding to the vehicle identification code.

Step S340: The vehicle terminal obtains the diagnosis script corresponding to the target diagnosis service from the cloud.

Step S350: The central domain controller of the vehicle parses the diagnostic script and obtains the diagnostic instructions.

Step S360: The central domain controller of the vehicle forwards the diagnosis instruction to the electronic control unit corresponding to the diagnosis instruction.

Step S370: The electronic control unit on the vehicle side executes the diagnostic task corresponding to the diagnostic instruction and returns the diagnostic result.

For detailed description of steps S310 to S370, please refer to steps S110 to S140 and steps S210 to S230, which will not be described again here.

During the specific implementation process, engineers synchronized the diagnostic scripts edited based on the actual diagnostic business to the cloud diagnostic cloud platform through the cloud script editing platform, so that other users using the same cloud can obtain updated diagnostic scripts in real time. When the script editing platform synchronizes diagnostic scripts to the diagnostic cloud platform, the information security server can also be used to perform signature authentication on the diagnostic scripts, making the diagnostic scripts more secure during synchronization.

After the user determines the target diagnostic service through the terminal, the terminal sends the diagnostic service and the vehicle identification code corresponding to the vehicle on which the diagnostic service is applied to the cloud, so that the cloud diagnostic cloud platform can accurately map the target diagnostic service to the cloud. The diagnostic script is sent to the corresponding vehicle terminal. During the data communication process between the cloud, the vehicle, and the terminal, the MQTT server is responsible for issuing diagnostic scripts and uploading diagnostic services and vehicle identification codes. The MQTT server sends the topic information with the diagnostic script to the Internet of Vehicles system (Telematics-BOX, TBOX). The Internet of Vehicles system extracts the payload of the MQTT information in the MQTT server, obtains the diagnostic information in the MQTT information, and This diagnostic information is sent to the virtual diagnostic instrument of the central domain controller. After receiving the diagnostic information, the virtual diagnostic instrument parses the payload of the diagnostic information and obtains the execution conditions in the diagnostic information. Query whether the current vehicle condition of the vehicle terminal meets the execution conditions of the diagnostic script. If the execution conditions are met, a script execution instruction is sent to the script interpreter. If it is not met, the execution condition is not met and returned to the cloud. After receiving the script running command, the script interpreter in the central domain controller starts running the diagnostic script, obtains the diagnostic command, and sends it to the diagnostic routing module. The diagnostic routing module parses the diagnostic command, obtains the source address and target address corresponding to the diagnostic command, and forwards the diagnostic command to the corresponding target electronic control unit according to the target address. The target electronic control unit performs diagnostic actions according to the diagnostic instructions and returns the diagnostic results to the terminal. According to the different diagnostic services sent by the terminal, the diagnostic script is sent to the vehicle terminal corresponding to the vehicle identification code, which can realize flexible configuration of the diagnostic script.
