[0054] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures, technologies, etc. are proposed so as to thoroughly understand the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, the detailed description of well-known systems, devices, circuits and methods is omitted to prevent unnecessary details from hindering the description of the present application. It should be understood that in the description of the present application specification and the attached claims, the terms "first", "second", "third", etc. are only used to distinguish descriptions and cannot be interpreted as indicating or suggesting relative importance.

[0055] It should also be understood that the references to "one embodiment" or "some embodiments" described in the specification of the present application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of the contents. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the various operations (or steps) as sequential processes, many of the operations therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the various operations can be rearranged. The process can be terminated when its operation is completed, but it can also have additional steps not included in the accompanying drawings. The process can correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.

[0056] At present, in the field of vehicle applications, vehicle identification, license plate processing, insurance registration, traffic accident handling, repair shop repair record, lost search and evidence collection, second-hand car transactions, accurate purchase of accessories, etc., all require vehicle identity verification based on the vehicle identification code (VIN). The vehicle identification code is like everyone's ID number, which can be used to uniquely identify the vehicle identity. So that manufacturers can monitor and feedback the quality of factory vehicles, as well as after-sales service spare parts management. However, in the second-hand car trading market, some merchants will modify the vehicle identification code in order to obtain higher profits, so as to achieve the purpose of low-configuration vehicles pretending to be high-configuration vehicles. In order to prevent this from happening, it is necessary to rely on professionals to verify the correctness of the vehicle identification code to determine the eligibility of the vehicle. Not only does it waste a lot of human resources, but it also cannot guarantee the accuracy of the results. In order to improve the accuracy and efficiency of vehicle verification, the embodiment of the present application provides a vehicle verification method, which can effectively verify the eligibility of the vehicle based on the vehicle identification code, so as to achieve the purpose of improving the accuracy and efficiency of vehicle verification. It can further provide assistance to the police's vehicle-related detection work.

[0057] See also Figure 1 , Figure 1 The present invention is a schematic diagram of the implementation process of the vehicle verification method provided in an embodiment of the application. In the embodiment of the present application, the vehicle verification device provided for executing the vehicle verification method can be a server or a terminal device in various vehicle management environments, the server can be a single server or a server cluster, and the terminal device can be a handheld terminal, a personal digital assistant PDA, a computer, a robot or a wearable smart device, etc.

[0058] like Figure 1 As shown, the vehicle diagnosis method provided in this embodiment includes S101 to S103. The details are as follows:

[0059] S101, obtaining a first vehicle identification code built into the vehicle.

[0060] It should be understood that the vehicle diagnostic device can establish a communication connection with the diagnostic interface of the on-board diagnostic system (OBD) to read the first vehicle identification code of the vehicle. The first vehicle identification code can also be obtained by scanning the vehicle logo, wherein the vehicle logo includes the first vehicle identification code. In some other cases, the vehicle identification code can also be obtained through the vehicle's central control platform.

[0061] Among them, the first vehicle identification code of the vehicle is the identification information built into each vehicle system when the vehicle leaves the factory, which is used to uniquely identify the vehicle, and is usually called the vehicle identification code, that is, the VIN code. In addition, the embodiment of the present application does not specifically limit the method of reading the vehicle identification code. For example, the vehicle verification device can also be provided with an operable display screen, and the display screen includes a vehicle identification code reading icon. The user can also trigger the instruction to read the vehicle identification code by operating the icon for reading the vehicle identification code, and obtain the vehicle identification code based on the instruction.

[0062] S102, obtaining a pre-registered second vehicle identification code of the vehicle from a vehicle information registration database, and matching the first vehicle identification code with the second vehicle identification code to obtain a matching result.

[0063] The matching of the first vehicle identification code and the second vehicle identification code to obtain a matching result includes: using a character segmentation recognition model to compare and match the first vehicle identification code and the second vehicle identification code to obtain a matching result.

[0064] Optionally, the character segmentation and recognition model segments and recognizes the first vehicle identification code to obtain a plurality of first VIN code characters, and segments and recognizes the second vehicle identification code to obtain a plurality of second VIN code characters; the plurality of first VIN code characters and the plurality of second VIN code characters are sequentially compared, and a matching result is determined based on the comparison result. For example, if after the plurality of first VIN code characters and the plurality of second VIN code characters are sequentially compared, the plurality of first VIN code characters are exactly the same as the plurality of second VIN code characters, then it is determined that the first vehicle identification code and the second vehicle identification code completely match. If any character in the plurality of first VIN code characters is not the same as a character in the plurality of second VIN code characters, then it is determined that the first vehicle identification code and the second vehicle identification code do not completely match.

[0065] S103: Generate and display verification result information of the vehicle according to the matching result.

[0066] Among them, the verification result information of the vehicle is generated and displayed according to the matching result, including: if the first vehicle identification code and the second vehicle identification code are exactly the same, then the information that the vehicle verification result is qualified is generated and displayed; if the first vehicle identification code and the second vehicle identification code are not exactly the same, then the information that the vehicle verification result is unqualified is generated and displayed.

[0067] It is understandable that when a user makes illegal modifications to a vehicle identification code, only some characters in the vehicle identification code can be modified, which can not only improve the modification efficiency of the vehicle identification code but also better hide the modification of the vehicle identification code. Therefore, as long as the first vehicle identification code and the second vehicle identification code are not exactly the same, for example, the letters are different, or the letters are exactly the same but the position order of the letters is different, it means that the first vehicle identification code is a modified vehicle identification code, and the corresponding vehicle verification result is unqualified. It can effectively check the modification of the vehicle identification code by illegal elements and improve the safety of the vehicle.

[0068] Through the above analysis, it can be known that the vehicle verification method provided in the embodiment of the present application reads the first vehicle identification code of the vehicle; obtains the second vehicle identification code of the vehicle pre-registered from the vehicle information filing library, matches the first vehicle identification code with the second vehicle identification code to obtain a matching result; generates and displays the verification result information of the vehicle according to the matching result. The vehicle's eligibility can be effectively verified based on the vehicle's identification code, thereby improving the accuracy and efficiency of vehicle verification.

[0069] For example, Figure 2 As shown, Figure 2FIG. 1 is a schematic diagram of an application scenario in which the vehicle verification method provided in the embodiment of the present application is applied to a vehicle management office server. Figure 2 It can be seen that in this embodiment, a vehicle verification system 201 is installed on the server 20, and the vehicle verification system 201 is an application integrated on the server 20 with a vehicle verification function. It should be understood that when the vehicle 21 needs to be verified through the server 20, a communication connection can be established with the vehicle 21 through the OBD diagnostic interface 210 to trigger the server 20 to run the vehicle verification system 201. In this embodiment, a Bluetooth communication connection or a network communication connection can be established between the server 20 and the OBD diagnostic interface 210 of the vehicle 21, and after the communication connection is established, the vehicle verification system 201 reads the first vehicle identification code of the vehicle 21, and obtains the second vehicle identification code of the vehicle pre-registered from the vehicle information filing library, matches the first vehicle identification code and the second vehicle identification code, and obtains a matching result; the verification result information of the vehicle is generated and displayed according to the matching result. Among them, the vehicle information filing library stores information such as vehicle factory information, vehicle license information or vehicle transaction information that needs to be filed at the vehicle management office. It should be understood that the vehicle identification information must be registered when the vehicle is filed at the vehicle management office.

[0070] In addition, if Figure 2 As shown, a police system 202 is also installed on the server 20. The server 20 can access the vehicle information filing library through the police system, and obtain the second vehicle identification code of the vehicle 21 pre-filed from the vehicle information filing library. It should be understood that in order to facilitate the tracing of vehicle problems, the vehicle management office requires the second-hand car market, repair shops and 4S shops to replace vehicle parts and other information in a timely manner. Upload the vehicle information to the vehicle management office for filing and registration. Therefore, the second vehicle identification code of the vehicle is the information that the vehicle 21 needs to register with the vehicle management office for identification of the vehicle 21. For example, the identification code of the vehicle 21 registered in the vehicle information filing library during the second-hand transaction of the vehicle 21, or the identification code of the vehicle 21 entered into the vehicle information filing library when the vehicle 21 is repaired, or the identification code of the vehicle 21 entered into the vehicle information filing library when the vehicle 21 is maintained at the 4S shop.

[0071] Through the above analysis, it can be known that the vehicle diagnostic method provided in the embodiment of the present application reads the first vehicle identification code built into the vehicle; obtains the second vehicle identification code of the vehicle pre-registered from the vehicle information filing library, matches the first vehicle identification code with the second vehicle identification code to obtain a matching result; generates and displays the verification result information of the vehicle according to the matching result. The vehicle's eligibility can be effectively verified based on the vehicle's identification code, thereby improving the accuracy and efficiency of vehicle verification.

[0072] For example, Figure 3 As shown, Figure 3 FIG. 1 is a schematic diagram of the implementation flow of a vehicle verification method provided by another embodiment of the present application. Figure 3 It can be seen that this embodiment and Figure 1 Compared with the embodiment shown, the specific implementation process of S301 to S303 is the same as that of S101 to S103, except that S304 and S305 are included after S303. The details are as follows:

[0073] S301, reading a first vehicle identification code built into the vehicle.

[0074] S302, obtaining a pre-registered second vehicle identification code of the vehicle from a vehicle information registration database, and matching the first vehicle identification code with the second vehicle identification code to obtain a matching result.

[0075] S303: Generate and display verification result information of the vehicle according to the matching result.

[0076] S304: If the first vehicle identification code and the second vehicle identification code are not exactly the same, obtaining the associated diagnostic information of the vehicle from the vehicle information filing library based on the second vehicle identification code, and tracing back the vehicle information change record based on the associated diagnostic information.

[0077] S305: Determine the change information of the first vehicle identification code based on the vehicle information change record, and generate warning prompt information based on the change information of the first vehicle identification code.

[0078] It can be understood that the first vehicle identification code is the read vehicle identification code, and the second vehicle identification code is the original VIN code of the vehicle stored in the vehicle information filing database. During the verification process, if the first vehicle identification code of the current vehicle matches the second vehicle identification code obtained, the current vehicle is determined to be qualified. If the first vehicle identification code of the current vehicle does not match the second vehicle identification code obtained, it means that the original VIN code of the corresponding vehicle has been modified, and the current vehicle is determined to be unqualified. Further, the information on the change of the vehicle identification code can be found by retrieving the data recorded in the vehicle information filing database. For example, the vehicle diagnostic maintenance records in the vehicle information filing database are traversed, the change information of the vehicle identification code is determined from the vehicle diagnostic maintenance records, and the geographical location appearing in the vehicle diagnostic maintenance record is queried according to the change information of the vehicle identification code, and then the repair link for executing the vehicle identification code change is confirmed based on the geographical location appearing in the diagnostic maintenance record, and the owner is reminded to pay attention. In addition, the vehicle management office confirms the subject that executes the vehicle identification code change according to the geographical location appearing in the diagnostic maintenance record, and requires the subject that executes the vehicle identification code change to be modified regularly. Among them, the entities that implement the vehicle identification code change include the used car market, repair shops and 4S stores. After determining the entities that implement the vehicle identification code change, the vehicle management office may further require them to make regular rectifications.

[0079] It should be understood that when the first vehicle identification code is not completely the same as the second vehicle identification code, the source of the second vehicle identification code can be traced back, and based on the source of the second vehicle identification code, the subject information of the first vehicle identification code to be changed is determined. That is to say, after obtaining the second vehicle identification code of the vehicle pre-registered from the vehicle information filing library, matching the first vehicle identification code and the second vehicle identification code, and obtaining the matching result, it can also include: tracing the source of the second vehicle identification code, and based on the source of the second vehicle identification code, determining the subject information of the first vehicle identification code to be changed.

[0080] Specifically, tracing the source of the second vehicle identification code and determining the subject information of changing the first vehicle identification code based on the source of the second vehicle identification code include: obtaining the vehicle's diagnostic maintenance record data from a vehicle information filing library, traversing the diagnostic maintenance record data based on the second vehicle identification code, and determining the target record in the diagnostic maintenance record data that involves changing the first vehicle identification code to the second vehicle identification code; querying the geographic location corresponding to the target record; and determining the subject information of changing the first vehicle identification code based on the geographic location.

[0081] It should be understood that since each link of the vehicle from production, sale to maintenance needs to be registered and filed with the vehicle management office, the possible nodes of the vehicle identification code change can be determined based on the registration and filing information of each link, and the subject that performs the change and the purpose of the subject change can be determined based on the changed node, so as to take corresponding control measures. For example, by traversing the vehicle's diagnostic records, according to the Electronic Control Unit (ECU) system involved in changing the vehicle identification code in the diagnostic records, the geographical location that appears in the vehicle diagnostic records can be queried, and then the subject that changes the vehicle can be determined based on the geographical location, and the purpose of changing the vehicle identification code can be predicted based on the identity of the subject. Among them, the subject information includes one of the following: used car dealers, repair shops, and car owners.

[0082] Through the above analysis, it can be known that the vehicle verification method provided by the embodiment of the present application reads the first vehicle identification code built into the vehicle; obtains the second vehicle identification code of the vehicle pre-registered from the vehicle information filing library, matches the first vehicle identification code with the second vehicle identification code to obtain a matching result; generates and displays the verification result information of the vehicle according to the matching result. The vehicle's eligibility can be effectively verified based on the vehicle's identification code, thereby improving the accuracy and efficiency of vehicle verification.

[0083] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
