Description

Technical Field

[0001] The present invention relates to the technical field of fault diagnosis, and in particular to a fault repair guidance method, device, equipment and storage medium. Background Art

[0002] Fault codes are an important input source for vehicle diagnosis and maintenance. Users locate vehicle problems through fault codes read by diagnostic equipment. With the continuous development of automotive electronics, more and more ECUs (Electronic Control Units) are installed in vehicles, and the electronic architecture is becoming more and more complex, which poses greater challenges to corresponding fault maintenance. Traditional reliance on the experience of maintenance technicians can no longer meet the current complex vehicle diagnosis. Obtaining maintenance guidance solutions through the Internet has become the main method of fault code maintenance.

[0003] The existing maintenance guidance scheme is to store the maintenance guidance scheme of each fault code in PDF (Portable Document Format) format on the server. When the user uses the diagnostic instrument to query the maintenance guidance scheme for the corresponding fault, the diagnostic software requests the corresponding PDF document from the network and displays it in the software. The technician uses the guidance document to troubleshoot the vehicle problem. However, fault codes are also divided into complex and simple ones. Complex fault codes can use PDFs with longer pictures and text to guide users to troubleshoot the problem, while simple fault codes only need simple text descriptions to quickly guide users. If PDFs are downloaded and the content is displayed for such simple fault codes, it will cause a relatively large burden on the network and memory, and the display efficiency will also decrease, resulting in a poor user experience.

[0004] As can be seen from the above, how to avoid burdening the network and memory and improve the display efficiency of fault codes is a problem that needs to be solved urgently. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] At present, complex fault codes can use PDFs with long images and text to guide users to troubleshoot problems, while simple fault codes only need simple text descriptions to quickly guide users. If simple fault codes also need to download PDFs and display content, it will cause a relatively large burden on the network and memory, and the display efficiency will also decrease, and the number of users will also be greatly reduced. To this end, the present application provides a fault repair guidance method, which flexibly and efficiently displays the target fault code repair guidance plan corresponding to the fault code of the target vehicle on the preset display interface of the diagnostic software, so as to perform fault repair operations based on the target fault code repair guidance plan, greatly reducing the waste of network and memory, thereby improving user experience and diagnostic efficiency.

[0049] See also Figure 1 As shown, an embodiment of the present invention discloses a fault repair guidance method, comprising:

[0050] Step S11, using diagnostic software to read vehicle information corresponding to the target vehicle, uploading the vehicle information to a preset server, so that a diagnostic data packet corresponding to the vehicle information can be downloaded through the preset server, and the diagnostic data packet can be sent to the diagnostic software.

[0051] In this embodiment, a communication relationship is first established between the diagnostic software and the target vehicle based on a preset communication protocol and a preset communication interface, and then the communication relationship and the diagnostic software are used to read the vehicle information corresponding to the target vehicle, and the vehicle information is uploaded to a preset server, so that the diagnostic data packet corresponding to the vehicle information can be downloaded through the preset server, and the diagnostic data packet can be sent to the diagnostic software. Specifically, the use of the diagnostic software to read the vehicle information corresponding to the target vehicle and upload the vehicle information to the preset server includes: establishing a communication relationship between the diagnostic software and the target vehicle based on a preset communication protocol and a preset communication interface, so that the diagnostic software uses the communication relationship to read the vehicle information corresponding to the target vehicle, and upload the vehicle information to the preset server.

[0052] It is understandable that any communication protocol that can establish a communication relationship between the diagnostic software and the target vehicle can be used as the preset communication protocol, and then based on the communication relationship and using the diagnostic software, a vehicle information reading request is sent to the target vehicle to read the vehicle information of the target vehicle, wherein the vehicle information includes vehicle identification number, engine model, software version, fault code, etc. The vehicle information is uploaded to the preset server through the diagnostic software, so that the corresponding diagnostic data packet can be searched and downloaded through the preset server and based on the vehicle information, and the diagnostic data packet is encapsulated into a preset data format and sent to the diagnostic software. It is worth mentioning that the preset data format can be adjusted based on the actual situation, and is not specifically limited here.

[0053] Step S12: sending a fault code reading command corresponding to the target vehicle generated based on the diagnostic data packet to an electronic control unit on the target vehicle to obtain a corresponding command reply result.

[0054] In this embodiment, after the diagnostic software receives the diagnostic data packet, the diagnostic data packet is parsed using the built-in parser or preset parsing algorithm of the diagnostic software to obtain a fault code reading command corresponding to the target vehicle, and the fault code reading command is sent to the electronic control unit on the target vehicle based on the communication relationship, so that the electronic control unit can perform a command reply to the received fault code reading command to obtain a corresponding command reply result. Specifically, the fault code reading command corresponding to the target vehicle generated based on the diagnostic data packet is sent to the electronic control unit on the target vehicle to obtain a corresponding command reply result, including: parsing the diagnostic data packet by the diagnostic software to generate a fault code reading command corresponding to the target vehicle, and sending the fault code reading command to each electronic control unit of the target vehicle, so that the electronic control unit can perform a command reply to the fault code reading command to obtain a corresponding command reply result.

[0055] Step S13, based on the command reply result, obtaining the fault code corresponding to the target vehicle, and querying the format type of the fault code repair guidance plan corresponding to the fault code and the target fault code repair guidance plan through the preset fault code library of the diagnostic software, so that the user can perform fault repair operations based on the target fault code repair guidance plan corresponding to the fault code displayed on the preset display interface of the diagnostic software; the format type of the fault code repair guidance plan includes a file type and a text type.

[0056] In this embodiment, after obtaining the command reply result, the fault code corresponding to the target vehicle is obtained from the command reply result, and then the format type of the fault code maintenance guidance scheme corresponding to the fault code and the corresponding target fault code maintenance guidance scheme are queried through the preset fault code library pre-created in the diagnostic software. The preset fault code library is created based on the complexity of the fault code. Specifically, before querying the format type of the fault code maintenance guidance scheme corresponding to the fault code and the target fault code maintenance guidance scheme through the preset fault code library of the diagnostic software, it also includes: judging whether the fault code meets the preset complexity condition; if the fault code meets the preset complexity condition, the target fault code maintenance guidance scheme corresponding to the fault code that meets the preset complexity condition is encapsulated as a file type and stored in the preset fault code library; if the fault code does not meet the preset complexity condition, the target fault code maintenance guidance scheme corresponding to the fault code that does not meet the preset complexity condition is encapsulated as a text type and stored in the preset fault code library.

[0057] It is understandable that if the fault code meets the preset complex conditions, that is, if the fault code is a fault code for a complex system, such as engine and drive related faults (such as some fault codes starting with P0), these faults may involve multiple systems of the engine, such as the fuel system, ignition system, emission system, etc. Since these systems are interrelated and complex, detailed graphic instructions are usually required to ensure the accuracy of maintenance. The guidance program corresponding to this type of fault code can be made into a file type (i.e. PDF type); if the fault code does not meet the preset complex conditions, it indicates that the fault code is a fault code for a non-complex system, such as insufficient tire pressure (tire pressure monitoring system warning light), and only a short text prompt is needed to remind the owner to check the tire pressure and replenish it to the normal range, so the guidance program corresponding to this type of fault code can be made into a string text type.

[0058] In this embodiment, after the preset fault code library is created, it is also necessary to set a corresponding fault code label in the preset fault code library, and the fault code label includes the fault code name, fault code description, fault code type, format type of fault code maintenance guidance scheme, target fault code maintenance guidance scheme and file download link corresponding to the fault code. Specifically, before obtaining the fault code corresponding to the target vehicle based on the command reply result and querying the format type of the fault code maintenance guidance scheme corresponding to the fault code and the target fault code maintenance guidance scheme through the preset fault code library of the diagnostic software, it also includes: setting the corresponding fault code label in the preset fault code library based on the fault code, and constructing the preset fault code library using each of the fault code labels; the fault code label includes the fault code name, fault code description, fault code type, format type of fault code maintenance guidance scheme, target fault code maintenance guidance scheme and file download link corresponding to the fault code.

[0059] Figure 2 A schematic diagram for creating a preset fault code library is provided for this embodiment, wherein a plurality of DTC tags are included in the DTC tag, and each DTC tag corresponds to the content of a fault code, including the fault code name, fault code description, fault code description, fault code level, etc. A new SDGS tag is added under the DTC tag, and the SDGS tag contains an SDG tag. If the format type of the fault code repair guidance plan corresponding to the fault code is a text type, a string is identified in the SDG tag, and the content is filled with the corresponding target fault code repair guidance plan; if the format type of the fault code repair guidance plan corresponding to the fault code is a file type, a PDF is identified in the SDG tag, and the content is filled with the file download link corresponding to the format type of the fault code repair guidance plan.

[0060] Furthermore, the format type of the fault code maintenance guidance scheme corresponding to the fault code is queried based on the created preset fault code library, and the corresponding target fault code maintenance guidance scheme is obtained based on the format type of the fault code maintenance guidance scheme. Specifically, the querying of the format type of the fault code maintenance guidance scheme corresponding to the fault code and the target fault code maintenance guidance scheme through the preset fault code library of the diagnostic software includes: querying the format type of the fault code maintenance guidance scheme corresponding to the fault code through the preset fault code library of the diagnostic software; if the format type of the fault code maintenance guidance scheme corresponding to the fault code is a text type, obtaining the target fault code maintenance guidance scheme corresponding to the format type of the fault code maintenance guidance scheme from the preset fault code library; if the format type of the fault code maintenance guidance scheme corresponding to the fault code is a file type, obtaining the file download link corresponding to the format type of the fault code maintenance guidance scheme from the preset fault code library, and downloading the corresponding target fault code maintenance guidance scheme based on the file download link.

[0061] In this embodiment, after obtaining the format type of the fault code maintenance guidance scheme corresponding to the fault code and the target fault code maintenance guidance scheme, it is necessary to create a preset help button on the preset display interface of the diagnostic software. When a click event for the preset help button corresponding to the fault code is detected, the target fault code maintenance guidance scheme corresponding to the fault code is displayed on the preset display interface, so that the user can perform fault maintenance operations based on the target fault code maintenance guidance scheme. Specifically, the method of obtaining the fault code corresponding to the target vehicle based on the command reply result and querying the format type of the fault code maintenance guidance scheme corresponding to the fault code and the target fault code maintenance guidance scheme through the preset fault code library of the diagnostic software also includes: creating a preset help button corresponding to the fault code on the preset display interface of the diagnostic software; when a click event for the preset help button corresponding to the fault code is detected, the target fault code maintenance guidance scheme corresponding to the fault code is displayed, so that the user can perform fault maintenance operations based on the target fault code maintenance guidance scheme.

[0062] Figure 3 A schematic diagram of a preset display interface provided in this embodiment. After querying the format type of the fault code repair guidance scheme corresponding to the fault code and the target fault code repair guidance scheme through the preset fault code library, the fault code information corresponding to the fault code is stored in a preset container. Figure 4A schematic diagram of a preset container structure provided for this embodiment. The fault code name, fault code description, fault code type, format type of the fault code repair guidance plan, target fault code repair guidance plan and file download link in the fault code information are stored in the preset container, so that the diagnostic software can parse each fault code information in the preset container and display each fault code information in the form of a list on the preset display interface. A corresponding preset help button is set after each fault code. When the user clicks the preset help button, the corresponding fault code information is queried based on the preset help button. Figure 5 A text display diagram of a preset display interface provided in this embodiment. If the format type of the fault code repair guidance plan corresponding to the fault code information is a text type, the corresponding target fault code repair guidance plan is directly displayed on the preset display interface; Figure 6 A file content display diagram of a preset display interface provided for this embodiment. If the format type of the fault code repair guidance plan corresponding to the fault code information is a file type, a file download link corresponding to the format type of the fault code repair guidance plan will be obtained first, and the target fault code repair guidance plan corresponding to the file download link will be displayed on the preset display interface.

[0063] As can be seen from the above, the file type and text content of the maintenance instruction file are defined according to the difficulty of the fault, and the preset fault code library of the diagnostic software is used to query the target fault code maintenance instruction plan corresponding to the format type of the fault code maintenance instruction plan corresponding to the fault code. In this way, the target fault code maintenance instruction plan corresponding to the fault code of the target vehicle is flexibly and efficiently displayed on the preset display interface of the diagnostic software, so that fault maintenance operations can be performed based on the target fault code maintenance instruction plan, greatly reducing the waste of network and memory, thereby improving user experience and diagnostic efficiency.

[0064] It can be seen from the above embodiments that the present application performs vehicle diagnosis on a target vehicle based on diagnostic software and a preset server. Therefore, the process of performing vehicle diagnosis on a target vehicle based on diagnostic software and a preset server is described.

[0065] See also Figure 7 As shown, the embodiment of the present invention discloses a specific fault repair guidance method, including:

[0066] In this embodiment, a communication relationship is first established between the diagnostic software and the target vehicle so that the diagnostic software can read the vehicle information corresponding to the target vehicle and upload the vehicle information to a preset server, so that after the preset server receives the vehicle information, it can search and download the diagnostic data packet corresponding to the vehicle information and send the diagnostic data packet to the diagnostic software; the diagnostic data packet is received by the diagnostic software, and a fault code reading command corresponding to the target vehicle is generated based on the diagnostic data packet, and the fault code reading command is sent to the electronic control unit on the target vehicle.

[0067] After the fault code reading command is received by the electronic control unit, the internal fault information is checked by the electronic control unit based on the fault code reading command to generate a corresponding command reply result, and the command reply result is sent to the diagnostic software. After the command reply result is received by the diagnostic software, the command reply result is parsed to obtain the fault code corresponding to the target vehicle. Then, the format type of the fault code maintenance guidance scheme corresponding to the fault code is queried using the pre-established preset fault code library, and the corresponding target fault code maintenance guidance scheme is obtained based on the format type of the fault code maintenance guidance scheme.

[0068] A preset help button corresponding to the fault code is created on the preset display interface of the diagnostic software, and when a click event of the preset help button corresponding to the fault code is detected, the target fault code maintenance guidance plan corresponding to the fault code is displayed. If the format type of the fault code maintenance guidance plan is a text type, the corresponding target fault code maintenance guidance plan is displayed on the preset display interface; if the format type of the fault code maintenance guidance plan is a file type, a file download link corresponding to the format type of the fault code maintenance guidance plan is obtained, and the target fault code maintenance guidance plan corresponding to the file download link is displayed on the preset display interface, so that the user can perform fault maintenance operations based on the target fault code maintenance guidance plan corresponding to the fault code displayed on the preset display interface of the diagnostic software.

[0069] As can be seen from the above, this embodiment uses diagnostic software to read the vehicle information of the target vehicle and upload it to the preset server, so as to download the corresponding diagnostic data packet based on the preset server, and use the diagnostic data packet to generate a fault code reading command and send it to the electronic control unit of the target vehicle, so as to return the corresponding command reply result through the electronic control unit, and use the fault code in the command reply result and the preset fault code library to query the format type of the corresponding fault code maintenance guidance plan and the target fault code maintenance guidance plan, so as to perform fault maintenance operations based on the target fault code maintenance guidance plan corresponding to the fault code displayed on the preset display interface of the diagnostic software. By displaying the fault code of the target vehicle on the preset display interface of the diagnostic software, the waste of network and memory can be reduced, and the accuracy and efficiency of diagnosis can be improved.
