[0038] 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.

[0039] Since the existing diagnostic software has deep function menu levels and complex pages, relevant personnel need to search layer by layer after starting the diagnostic software during use. It is easy for them to find it difficult to find the target menu they need in a short time due to unfamiliarity with the software, thus wasting a lot of time. At the same time, the intelligent search function configured in the device is usually unusable due to the lack of Internet access, making it difficult to quickly find the target menu. If values ​​need to be transferred between pages, the complexity of the software will be increased during the layer-by-layer search process, and data errors may occur easily due to unstable data transmission mechanisms. The overall user experience of the diagnostic equipment is poor, and the diagnostic efficiency is low.

[0040] In order to overcome the above technical problems, the present application provides a vehicle diagnosis method to simplify the menu search and page value transfer process of the diagnostic software to improve the diagnostic efficiency and realize offline diagnosis.

[0041] See also Figure 1 As shown, an embodiment of the present invention discloses a vehicle diagnosis method, which is applied to a diagnostic device, including:

[0042] Step S11, determining target-related data from a local database based on the received search instruction, and displaying the target-related data on a front end of the diagnostic device in a preset display manner, so as to receive a corresponding selection instruction through the front end.

[0043] In this embodiment, the diagnostic device receives the search instruction through the preset interface, and determines the target-related data from the local database according to the search instruction, so as to display the target-related data in a preset display mode on the front end of the diagnostic device, so as to receive the corresponding selection instruction through the front end. The preset interface can be the front end of the diagnostic device; the search instruction is an instruction initiated through the preset interface when the user has a search demand.

[0044] Specifically, this embodiment can determine the target keyword based on the received search instruction, and scan the local database to determine the target-related data related to the target keyword; and display the target-related data in the form of a list on the front end of the diagnostic device. That is, first determine the target keyword in the search instruction according to the received search instruction, and scan the local database to determine the target-related data related to the target keyword in the local database, and display the target-related data in the form of a list on the front end of the diagnostic device, so that the user can select the target-related data through the front end, and then receive the selection instruction initiated by the user through the front end. Among them, the user refers to the person who uses the diagnostic device, including but not limited to vehicle maintenance personnel, vehicle owners, etc. It can be understood that in addition to displaying in the form of a list, the preset display method can also be displayed in the form of a grid arrangement.

[0045] It should be pointed out that the local database contains relevant information of the diagnostic software and relevant information of the system menus at all levels in the diagnostic software. Among them, the relevant information of the diagnostic software includes SW_ID (i.e., software package identifier), corresponding multilingual expressions, and version information, and the relevant information of the system menus at all levels includes menu IDs (i.e., menu identifiers) such as MENU_ID_1 and MENU_ID_2, data to be transmitted by each menu, and corresponding multilingual expressions. That is, the vehicle diagnostic method of this embodiment is applied to the diagnostic device. After the diagnostic device receives the search instruction initiated by the user, the target keyword that the user needs to search is determined, and the target keyword is compared and matched with the corresponding multilingual expressions of the diagnostic software and the corresponding multilingual expressions of the system menus at all levels stored in the local database of the diagnostic device in a fuzzy matching manner, so as to determine the multilingual expressions that can match the target keyword as the data to be displayed, that is, the target-related data, and display the data to be displayed to determine the diagnostic program that the user wants to execute and complete the vehicle diagnosis.

[0046] It should be further pointed out that the diagnostic device of this embodiment has an application called an upgrade center, which contains a data packet of diagnostic software. Developers can provide or update the data of the corresponding diagnostic software to users through the upgrade center, and users can update the local database through the upgrade center. Specifically, after the developer uploads the relevant data of the integrated diagnostic software to the diagnostic device, the diagnostic device of this embodiment determines the data to be uploaded based on the received upload instruction, and stores the data to be uploaded in a file of a preset format; encrypts the file using a second preset encryption algorithm, and uploads the encrypted file to the local upgrade center. Among them, the second preset encryption algorithm can be an AES (Advanced Encryption Standard) encryption algorithm. That is, the diagnostic device first receives the data to be uploaded in the upload instruction, stores the data to be uploaded in a file of a preset format, encrypts the file using a second preset encryption algorithm to reduce the risk of data theft, and uploads the encrypted file to the local upgrade center. It should be noted that during this period, the file is released according to the version of the diagnostic software, and the user can determine whether the diagnostic software in his diagnostic device needs to be updated by checking the version information. At the same time, considering that bin files (a binary file format) have the advantages of efficient space utilization, fast storage, and data that is not easily tampered with, the file in the preset format can be a bin file, so as to improve data security and ensure space utilization. Specifically, when the user initiates a data packet download instruction from the upgrade center through the front end, the diagnostic device downloads the target version of the diagnostic software from the upgrade center based on the received download instruction, and after the download is successful, the diagnostic software is decrypted to obtain the decrypted data; the data stored in the local database is updated according to the decrypted data. That is, first obtain the target version of the diagnostic software that needs to be downloaded in the download instruction, then download the target version of the diagnostic software from the upgrade center, and after the download is successful, decrypt the bin file of the diagnostic software to obtain the decrypted data in the bin file, so as to update the data stored in the local database according to the decrypted data. In this way, the present embodiment can support the user to input the target keyword to be searched through the preset interface, and search for relevant data based on the target keyword for the user to select, without the user having to select from the menu layer by layer, thus realizing the function of intelligent search and improving the user experience; at the same time, the data are all stored in the local database of the diagnostic equipment, and the diagnosis can be completed without networking during the diagnostic process, thus realizing offline diagnosis and expanding the application scenarios; and the relevant data of the diagnostic software is encrypted for transmission, thus improving the security of the data and reducing the risk of data theft.

[0047] Step S12: determining a corresponding menu path according to the selection instruction, and when a diagnostic program under the menu path needs to be transmitted, determining the data to be transmitted corresponding to the menu path from the local database.

[0048] In this embodiment, the diagnostic device determines a corresponding menu path according to the received selection instruction, and when the diagnostic program under the menu path needs to be transmitted, determines the data to be transmitted corresponding to the menu path from the local database.

[0049] It should be noted that the processing flow of determining the corresponding menu path according to the selection instruction is as follows: determining the target selection data from the target-related data according to the selection instruction, and combining the identifiers of the target selection data to obtain the corresponding menu path. That is, in addition to the multilingual expression, the target-related data also includes the menu ID corresponding to the multilingual expression and the IDs of the various levels of menus related to the multilingual expression, that is, the identifiers. In this embodiment, the target selection data, that is, the data selected by the user, is first determined from the target-related data according to the selection instruction, and the identifiers of the target selection data are combined to obtain the combined corresponding menu path. For example, when the user clicks on the menu item of Wabco in the demonstration program, the diagnostic device determines the menu path corresponding to "Demonstration Program V15.11>International>ABS (Anti-lock Braking System)>Wabco". In this path, when the diagnostic program under the menu path needs to be transmitted, the embodiment can determine the data to be transmitted corresponding to the various levels of menus under the menu path stored therein from the local database, that is, the data to be transmitted. In this way, this embodiment first determines the corresponding menu path and the data to be transmitted according to the selection instruction initiated by the user, so as to quickly jump to the menu path, and after receiving the user's diagnostic instruction, starts the diagnostic program under the menu path based on the data to be transmitted, thereby improving the efficiency of vehicle diagnosis.

[0050] Step S13, jump to the menu path to determine the diagnostic program under the menu path, and after receiving the target diagnostic instruction, transmit the data to be transmitted to the diagnostic program in an encrypted form, so as to start the diagnostic program based on the data to be transmitted and diagnose the vehicle to be diagnosed.

[0051] In this embodiment, the diagnostic device jumps to the menu path to determine the diagnostic program under the menu path, and after receiving the target diagnostic instruction, transmits the data to be transmitted to the diagnostic program in an encrypted form, so as to start the diagnostic program based on the data to be transmitted and diagnose the vehicle to be diagnosed. The target diagnostic instruction may be an instruction initiated by the user clicking a corresponding diagnostic button on the front end.

[0052] It should be noted that the processing flow of transmitting the data to be transmitted to the diagnostic program in an encrypted form is as follows: encrypting the data to be transmitted using a first preset encryption algorithm to obtain encrypted data; transmitting the encrypted data to the diagnostic program in a preset format so that the diagnostic program decrypts the encrypted data and diagnoses the vehicle to be diagnosed based on the corresponding decrypted data. Among them, the first preset encryption algorithm can be an MD5 encryption algorithm (a cryptographic hash function), and the preset format can be a JSON format (i.e., JavaScript ObjectNotation, a lightweight data exchange format). That is, the data to be transmitted is encrypted using a first preset encryption algorithm to obtain encrypted data, and the encrypted data is transmitted to the diagnostic program in a preset format so that the diagnostic program decrypts the encrypted data and diagnoses the vehicle to be diagnosed based on the corresponding decrypted data, thereby completing the function of secure value transmission and improving data security.

[0053] It should be further pointed out that, since the operation of diagnosing the vehicle to be diagnosed through the diagnostic device requires ensuring that the diagnostic device has established a stable communication connection with the vehicle to be diagnosed, before the diagnostic program is started based on the data to be transmitted and the vehicle to be diagnosed is diagnosed, the following processing flow is also required: if it is detected that the local Bluetooth is not started, the Bluetooth is started to establish a Bluetooth connection with the vehicle to be diagnosed, so as to diagnose the vehicle to be diagnosed using the diagnostic program. That is, when the diagnostic device detects that the local Bluetooth is not started, the Bluetooth is automatically started to establish a Bluetooth connection with the vehicle to be diagnosed, so as to diagnose the vehicle to be diagnosed using the diagnostic program through the Bluetooth connection. It is understandable that there is also a situation where the local Bluetooth of the diagnostic device has been started, but a Bluetooth connection with the vehicle to be diagnosed has not been successfully established. At this time, manual intervention is required to analyze the situation and perform corresponding operations based on the results of the analysis. For example, if the Bluetooth is activated, but the Bluetooth of the diagnostic device has established a Bluetooth connection with other vehicles except the vehicle to be diagnosed, the connection channel is occupied and cannot be connected to the vehicle to be diagnosed. At this time, the user needs to manually operate the diagnostic device to establish a Bluetooth connection with the vehicle to be diagnosed in order to diagnose the vehicle to be diagnosed. In this way, this embodiment transmits the data to be transmitted to the diagnostic program in an encrypted form, completes the function of secure value transmission, and improves data security; and before starting the diagnostic program and diagnosing the vehicle to be diagnosed, it automatically detects whether Bluetooth is activated, and activates Bluetooth when it is detected that it is not activated, so as to determine that the diagnostic device has established a communication connection with the vehicle to be diagnosed, thereby avoiding the occurrence of diagnostic failure due to failure to establish a connection with the vehicle to be diagnosed.

[0054] As can be seen from the above, the embodiment of the present application first determines the target-related data from the local database based on the received search instruction, and displays the target-related data on the front end of the diagnostic device, so as to receive the selection instruction through the front end, and determine the menu path through the selection instruction, and determine the data to be transmitted corresponding to the menu path when it is necessary to transmit a value, so as to jump to the menu path, determine the diagnostic program under the menu path, and after receiving the target diagnostic instruction, transmit the data to be transmitted to the diagnostic program in an encrypted form, so as to start the diagnostic program based on the data to be transmitted, and diagnose the vehicle to be diagnosed. In this way, through the above process of the embodiment of the present application, on the one hand, the data are all stored in the local database of the diagnostic device, and the data in the local database can be used to search for menu paths during the diagnosis process, and the diagnosis can be completed without connecting to the Internet, realizing offline diagnosis and expanding the application scenarios; on the one hand, it can support the user to input the target keyword to be searched through the preset interface, and search for relevant data based on the target keyword for the user to select, without the user having to select the menu layer by layer, and provide an intelligent search function so that relevant personnel can quickly find the required menu path, thereby improving the user experience; on the one hand, after receiving the target diagnosis instruction, the data to be transmitted is directly transmitted to the diagnostic program, and the operation of transmitting data in multiple interfaces on one page is completed at one time; on the one hand, the relevant data of the diagnostic software is encrypted and transmitted, thereby improving the data Security, reducing the risk of data theft; on the one hand, the corresponding menu path and the data to be transmitted are determined according to the selection instruction initiated by the user, so as to quickly jump to the menu path, and after receiving the user's diagnostic instruction, the diagnostic program under the menu path is started based on the data to be transmitted, thereby improving the efficiency of vehicle diagnosis; on the one hand, the data to be transmitted is transmitted to the diagnostic program in an encrypted form to complete the function of secure value transmission, thereby improving the security of data; on the other hand, before starting the diagnostic program and diagnosing the vehicle to be diagnosed, it automatically detects whether Bluetooth is started, and starts Bluetooth when it is detected that it is not started, so as to determine that the diagnostic device has established a communication connection with the vehicle to be diagnosed, thereby avoiding the occurrence of diagnostic failure due to failure to establish a connection with the vehicle to be diagnosed, thereby simplifying the menu search and value transmission process between pages of the diagnostic software to improve diagnostic efficiency and realize offline diagnosis.

[0055] Accordingly, see Figure 2 As shown, the embodiment of the present application also provides a vehicle diagnostic device, which is applied to a diagnostic device, including:

[0059] As can be seen from the above, the embodiment of the present application first determines the target-related data from the local database based on the received search instruction, and displays the target-related data on the front end of the diagnostic device, so as to receive the selection instruction through the front end, and determine the menu path through the selection instruction, and determine the data to be transmitted corresponding to the menu path when the value needs to be transmitted, so as to jump to the menu path, determine the diagnostic program under the menu path, and after receiving the target diagnostic instruction, transmit the data to be transmitted to the diagnostic program in an encrypted form, so as to start the diagnostic program based on the data to be transmitted, and diagnose the vehicle to be diagnosed. In this way, through the above process of the embodiment of the present application, the menu path is searched using the data in the local database, and offline diagnosis is realized.
