Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a method and device for information feedback based on a vehicle identification number. Background Art

[0002] With the increasing production of automobiles, various types of vehicles are gradually becoming popular among the working class. Every vehicle has a vehicle identification number; through the vehicle identification number, you can quickly understand the relevant basic information of the vehicle, such as the year, model, engine, etc. And in terms of vehicle use, the vehicle identification number (VIN) can also play a certain role. For example, when a technician uses a vehicle diagnostic tool to diagnose a vehicle to be tested, he can obtain information such as the model, manufacturer, and manufacturing time of specific vehicle components based on the vehicle's VIN, and accurately match the corresponding vehicle diagnostic module to effectively diagnose and repair the vehicle.

[0003] At present, in the application process of VIN, the amount and types of vehicle information obtained based on VIN are limited. Moreover, the VIN standards adopted by different automobile manufacturers may be different, and the meaning of each character of VIN in different standards and different countries is also different. The above situation causes inefficiency and inconvenience in the actual application of VIN, which is often far from the real goal and expected effect.

[0004] Therefore, how to efficiently use VIN to obtain relevant information is an urgent problem to be solved in this application. Summary of the invention

[0005] The present application provides a vehicle identification number-based information feedback method and device, which can determine specific component information of a vehicle according to the VIN, thereby facilitating subsequent vehicle use and automobile diagnosis and other services.

[0006] In the first aspect, an embodiment of the present invention provides an information feedback method based on a vehicle identification number, which may include: obtaining the vehicle identification number VIN of a target vehicle; determining one or more first information matching the target vehicle based on the VIN, the one or more first information being used to describe vehicle characteristics of the target vehicle; determining one or more second information from the one or more first information based on target components or target functions of the target vehicle; the one or more second information being used to determine vehicle usage services corresponding to the target vehicle.

[0007] In an embodiment of the present invention, one or more first information matching the vehicle is obtained by obtaining a VIN and based on the VIN; wherein the first information may include a vehicle body type, a vehicle model series, and a manufacturer, etc. One or more first information may define or describe the characteristics of the target vehicle, and determine the specific information of the vehicle, for example, the vehicle is determined to be an Audi A3 Sportback 2020 model through the VIN. According to the content specified by the target component or the target function, the second information is determined from the first information; and accurate vehicle service items may be provided to the user according to the second information. For example, in the process of vehicle diagnosis, all vehicle information about vehicle A is obtained according to the VIN of vehicle A; according to the component (such as the engine) targeted by the diagnosis, various parameters such as the engine model are determined to match the most suitable diagnostic module, so as to facilitate the subsequent diagnosis. By implementing the embodiment of the present invention, the VIN of the vehicle can be effectively used to obtain the corresponding vehicle information, improve the efficiency of subsequent vehicle information use, and improve the user experience. Further optionally, the second information is directly determined according to the VIN and specific user needs (such as a certain vehicle function).

[0008] In a possible implementation, the method of obtaining the vehicle identification number (VIN) of the target vehicle includes: obtaining an image containing the VIN; and determining the VIN according to the image and a preset recognition algorithm. In the embodiment of the present invention, by first recognizing the image and then obtaining the VIN in the image, the diversity and efficiency of the methods for obtaining the VIN are enriched.

[0009] In a possible implementation, the determining one or more second information from the one or more first information according to the target component or target function of the target vehicle includes: filtering out the component information corresponding to the target function from the one or more first information as the one or more second information according to the name of the target function; or filtering out the component information corresponding to the target component from the one or more first information as the one or more second information according to the name of the target component. In an embodiment of the present invention, the second information is filtered out from the first information by the name of the target function or the name of the target component, so that the second information related thereto can be determined relatively accurately. Among them, the name of the target function and the name of the target component can be detailed and specific, a general term or an alias. In an embodiment of the present invention, the first information is filtered out according to the name of the target function or the target component to obtain the second information, and the information that meets the requirements is purposefully obtained from a large amount of information, which is conducive to improving the efficiency of information utilization.

In an embodiment of the present invention, after the VIN of the vehicle is determined, data is returned and enriched for the database related to the VIN to further improve the database related to the VIN. For example, in the process of the vehicle using the service, the process of service use and the corresponding diagnostic object parameters are recorded throughout the process. In the case of missing necessary diagnostic information or units, the missing necessary information or / and units are recorded. In the case of information existence, for different data of the information or data with a newer recording date, the new data replaces the old data and forms historical information or the new data is added on the basis of retaining the old data.

[0014] In a possible implementation, after obtaining and identifying the vehicle identification code VIN, based on the information obtained from the VIN and the functional requirements of the user, the required functions can be provided to the user within the scope of the functions or data stored in the database. For example, based on the VIN of vehicle A, communication links are established with several related databases. There are three functions a, b, and c in the database that can be provided to the user, and the user can obtain one of the three according to specific needs. However, for needs beyond the aforementioned three functions, the existing vehicle-related data can be screened, classified, or integrated according to the needs to form or facilitate the subsequent formation of a new database for user calls.

[0031] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0032] The terms "first", "second", "third" and "fourth" etc. in the specification and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] First, some terms in the embodiments of the present invention are explained to facilitate understanding by those skilled in the art.

[0035] (1) Vehicle Identification Number (VIN), or chassis number, is a set of seventeen letters or numbers that are used on a car as a unique number that can identify the car's manufacturer, engine, chassis serial number, and other performance information. The meaning of each bit in the VIN produced by different manufacturers may be different. At present, there are two main VIN formats. The first is the ISO3779 standard adopted by the European Union, and the second standard is mainly used in North America. The two standards are still compatible with each other. For example, through the VIN, you can obtain relevant information such as the vehicle's country of production, manufacturer, model category, occupant safety protection device, model series, body type, engine model, VIN inspection number, model year, assembly plant, and production sequence number.

[0036] (2) On Board Diagnostics (OBD) monitors the exhaust gas level of the vehicle at any time according to the engine's operating status. Once the exhaust gas level exceeds the standard, an alarm will be issued immediately. When a system fault occurs, the Malfunction Indicator Lamp (MIL) or the Check Engine warning light will light up, and the Powertrain Control Module (PCM) will store the fault information in the memory. The fault code can be read from the PCM through a certain program. Based on the fault code prompt, maintenance personnel can quickly and accurately determine the nature and location of the fault. One of the mature functions of OBDⅡ is that when the system lights up the fault light, it records the data of all sensors and drivers, which can meet the needs of diagnosis and maintenance to the greatest extent. The computer capacity of this system has not only been greatly improved, but it can also track the damage of components. OBD monitors the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, exhaust gas recirculation system (EGR) and other systems and components in real time.

[0037] (3) The components of a vehicle generally include chassis, engine, body and electrical equipment. The chassis of a vehicle is composed of four parts: transmission system, running system, steering system and braking system. The function of the chassis is to support and install the vehicle engine and its components and assemblies to form the overall shape of the vehicle, and to receive the power of the engine so that the vehicle can move and run normally according to the control.

[0038] The engine is used to generate power and convert the heat energy generated by the combustion of fuel into mechanical energy; it is generally composed of a crank-connecting rod mechanism, a valve mechanism, a fuel supply system, a cooling system, a lubrication system, an ignition system, and a starting system.

[0039] The part of the vehicle body used to carry people and cargo, or the entire vehicle. It generally includes windows, doors, cockpit, passenger compartment, engine compartment, and luggage compartment. The body shape includes box, fish, boat, flow, and wedge, etc.; the structural form can be divided into single compartment, two compartments, and three compartments.

[0040] Electrical equipment that meets the needs of automobile power consumption and control. Generally includes power pack (battery), (starter) engine starting system and ignition system, lighting and signal devices, electronic control devices, etc. Vehicles may also include other accessories / components: wipers, seats, dashboards, bumpers, seat belts, airbags.

[0041] The information feedback method based on the vehicle identification number involved in the present application is further described in detail below in conjunction with the accompanying drawings.

[0042] See also Figure 1 , Figure 1 is a schematic diagram of a vehicle diagnosis scenario based on a vehicle identification number provided by an embodiment of the present invention; Figure 1 As shown, the scenario includes vehicles (such as vehicle 1, vehicle 2, ..., vehicle N shown in the figure; wherein the vehicles shown in the figure can be distinguished by model or series, etc.), diagnostic equipment and servers; a certain part of the vehicle is generally marked with a VIN, such as in the engine compartment, on the front windshield, etc. The embodiment of the present invention is not limited to this. Among them,

[0043] The vehicle is a vehicle to be diagnosed or tested; the vehicle in the application scenario needs to have at least a valid VIN, which can be obtained by a third-party device such as a diagnostic device. The type of vehicle is not limited in the embodiments of the present invention. The diagnostic device can diagnose a variety of vehicles, such as providing corresponding services after obtaining the vehicle VIN.

[0044] The diagnostic device can obtain the VIN by scanning a QR code, receiving a user's direct input of the VIN, or identifying the VIN after taking a photo of the vehicle. Optionally, the diagnostic device can include full-scene recognition for VIN, such as the front windshield, driving license, engine nameplate, motor vehicle registration certificate, etc.; it can also support full-car recognition, such as domestic cars, imported cars, etc.; the style of the recognition object can also include black characters on a white background, white characters on a black background, steel stamps, and special-shaped characters. It is understandable that the diagnostic device can also include a program dedicated to identifying the VIN, so that the VIN can be normally identified for pictures taken at different angles. The embodiment of the present invention is not limited to the diagnostic device obtaining the VIN. Optionally, the mobile terminal captures and identifies a picture containing the VIN, identifies the picture, and then sends the identified VIN to the diagnostic device. The diagnostic device matches the corresponding diagnostic module or program, system, etc. according to the received VIN. In this application scenario, the diagnostic device can obtain the VIN of the vehicle from the vehicle, establish a connection with the server, obtain vehicle data related to the VIN, and provide corresponding vehicle use services based on the vehicle data.

[0045] A server is a device that efficiently processes and stores data. In this application scenario, the diagnostic device can search the server for all vehicle information related to the VIN for the vehicle when connected to the network. The server can host and run one or more databases. The server can be one or more computers; this is not limited in the embodiments of the present invention.

[0046] It should be noted that this application scenario is only an exemplary scenario description; the application scenarios involved in the embodiments of the present invention include but are not limited to the above application scenarios.

[0047] See also Figure 2 , Figure 2 is a flow chart of information feedback based on a vehicle identification number provided by an embodiment of the present invention; Figure 2 As shown, the method embodiment takes the diagnostic device as an example of the execution subject and is explained from the side of the diagnostic device, and specifically may include steps S201 to S203.

[0048] Step S201: Obtain the vehicle identification number VIN of the target vehicle.

[0049] Specifically, the diagnostic device can obtain the VIN of the target vehicle by receiving the VIN input by the user, or identifying the VIN information contained in the picture, or scanning the QR code to indirectly read the VIN of the vehicle. The embodiment of the present invention does not limit the method of obtaining the VIN; specifically, the diagnostic device can also obtain the VIN of the target vehicle from the network or database when connected to the network.

[0050] In a possible implementation, the method of obtaining the vehicle identification number VIN of the target vehicle includes: obtaining an image containing the VIN; and determining the VIN based on the image and a preset recognition algorithm. Specifically, the diagnostic device can obtain the VIN of the vehicle through a picture of the target vehicle. For example, the picture contains image information of the VIN, and the VIN is recognized through an image recognition algorithm; or the diagnostic device may also include a camera module (such as a lens), and after turning on the camera function, the VIN is recognized based on the operating instructions of the diagnostic device (for example, there is an identification box in the interface of the diagnostic device, and when the lens is at a certain angle, the VIN can roughly fall within the range of the identification box). For another example, the VIN corresponding to the vehicle is obtained by the license plate number or by recognizing a picture containing the license plate information.

[0051] Step S202: determining one or more first information matching the target vehicle according to the VIN.

[0052] Specifically, the diagnostic device determines one or more first information of the target vehicle according to the VIN of the target vehicle. Among them, one or more first information is used to describe the vehicle characteristics of the target vehicle. The first information may include information related to various aspects of the vehicle, such as the year of manufacture, manufacturer, engine model, country of manufacture, vehicle model, and vehicle series. In an embodiment of the present invention, the required vehicle information can be obtained directly from the VIN according to the needs of the user or the settings of the device; or all relevant vehicle information can be obtained from the VIN first and then filtered according to the set filtering conditions.

[0053] Optionally, the VIN not only includes multiple vehicle part numbers of a vehicle, but may also correspond to a certain part number of the vehicle; the same part number may be included in the information of multiple VINs.

[0054] In a possible implementation, the determining one or more first information matching the target vehicle according to the VIN includes: determining one or more databases corresponding to the VIN according to the VIN; determining one or more first information matching the target vehicle from the one or more databases. For example, all information about the vehicle is obtained from the aforementioned database based on the VIN, and all information includes the vehicle type, vehicle series, and manufacturer corresponding to the VIN in general; and related information about specific parts or components of the vehicle. And basic vehicle functions or personalized functions. Among them, the database may include the structural composition, type, etc. of the vehicle.

[0055] Optionally, the diagnostic device can also determine specific functional information corresponding to the target vehicle based on the VIN, such as cooling function, starting function, braking function, etc.; the diagnostic device can also determine one or more vehicle components in the vehicle system corresponding to the function, for example, the vehicle structure corresponding to the cooling function may include a radiator, a thermostat, a water temperature gauge, etc.

[0056] Further optionally, the diagnostic device can split the VIN string into several segments, such as three segments, according to a preset splitting rule. Each segment can correspond to a type of vehicle function or a certain vehicle system. One or more characters in each segment can correspond to a function; for example, a digit in the digital string represents the start function of the vehicle. Alternatively, multiple characters represent a certain function or machine type of the vehicle. The vehicle function can include some or all functions in each system of the target vehicle.

[0057] Step S203: determining one or more second information from the one or more first information according to the target component or target function of the target vehicle.

[0058] Specifically, the diagnostic device determines one or more second information from one or more first information according to preset user needs or preset information processing rules, and feeds back one or more of the second information to the user according to corresponding needs. The one or more second information is used to determine the vehicle usage service corresponding to the target vehicle. The second information may include information about the vehicle structure or vehicle components contained in the target vehicle. Among them, the purpose and specific content of the second information are closely related to the user's choice. The embodiment of the present invention does not limit this.

[0059] In a possible implementation, the determining one or more second information from the one or more first information according to the target component or target function of the target vehicle includes: filtering out the component information corresponding to the target function from the one or more first information as the one or more second information according to the name of the target function; or filtering out the component information corresponding to the target component from the one or more first information as the one or more second information according to the name of the target component. For example, the diagnostic device receives the function name "cooling function" input by the user, and filters the specific parameters, models and other information of the components or parts (such as radiator, thermostat, water pump, etc.) in the vehicle corresponding to the cooling function from the multiple first information. For another example, the component name received by the diagnostic device is "brake pump", and the information or data related to the brake pump of the vehicle is filtered out from the multiple first information according to the name of the component.

[0060] For example, information related to the vehicle engine is automatically determined based on the type of diagnostic equipment (e.g., diagnostic equipment for a certain component or structure, such as an engine diagnostic equipment). Second information (here, information related to the engine) is selected from one or more first information and provided or fed back to the user. For example, from a large range of data (i.e., the first information) to a small range of data (i.e., the second information), the brand (e.g., Audi), model (including the grade of the car, such as A3), production year (e.g., 2008), displacement, production place, engine condition and other auxiliary information can be determined first (there can also be a body type, such as SUV, which is more about the purpose and functionality of the car), and the basic situation of the car can be basically determined. After the model is roughly determined, the vehicle situation can also be accurately determined based on the determination of detailed features or name differences. For example, the name alone cannot be directly distinguished, and other information such as the vehicle displacement and engine must be combined to determine which model the car is.

[0061] Optionally, before determining the second information from the first information set, a target function name or a target component name of the target vehicle may be determined first.

[0062] In an embodiment of the present invention, a VIN is obtained and one or more first information matching the vehicle is obtained based on the VIN; wherein the first information may include vehicle body type, vehicle model series, and manufacturer, etc. The required second information is then determined from the first information; based on the second information, accurate vehicle service items can be provided to the user. For example, during vehicle diagnosis, all vehicle information about vehicle A is obtained based on the VIN of vehicle A; based on the components targeted by the diagnosis (such as the engine), various parameters such as the engine model are determined to match the most appropriate diagnostic module, so as to facilitate subsequent diagnosis. By implementing an embodiment of the present invention, the VIN of the vehicle can be effectively used to obtain corresponding vehicle information, improve the efficiency of subsequent vehicle information use, and improve the user experience.

[0063] See also Figure 3 , Figure 3 is another flow chart of information feedback based on a vehicle identification number provided by an embodiment of the present invention; Figure 3 As shown, the method embodiment is described by taking the diagnostic device side as an example, and may specifically include steps S301 to S303; optional steps may also include steps S304, S305, S306, S307, S308 and S309.

[0064] Step S301: Obtain the vehicle identification number VIN of the target vehicle.

[0065] For details, please refer to the aforementioned step S201.

[0066] Step S302: determining one or more first information matching the target vehicle according to the VIN.

[0067] For details, please refer to the aforementioned step S202.

[0068] Step S303: Determine one or more second information from the one or more first information according to the target component or target function of the target vehicle.

[0069] For details, please refer to the aforementioned step S203.

[0070] Step S304: Determine a vehicle diagnostic module that matches the target function or target component according to the one or more second information.

[0071] Specifically, after determining the second information, obtain the model, usage method, precautions and corresponding diagnostic module or method of one or more parts corresponding to the target vehicle. The vehicle usage service is a vehicle diagnostic service. For example, it is determined that the engine of the vehicle needs to be diagnosed, and the specific model and production date of the vehicle engine and other detailed information are determined through the VIN of the vehicle, and then the diagnostic module adapted to it is matched through the aforementioned detailed information. In particular, when the second information is about the underlying functional information of the vehicle, the diagnostic module for the components involved in the underlying functions can be determined through the second information. After determining the diagnostic module, the diagnostic equipment can use these diagnostic modules to conduct a comprehensive diagnosis of the underlying functions and underlying systems of the target vehicle, such as the anti-theft system, engine system and brake system, etc. It can be understood that for the diagnosis of the general structure, components or systems of the vehicle, the diagnostic equipment can also filter out the second information from the first information according to the needs of the user, and then perform a routine diagnosis on the vehicle.

[0072] Step S305: Diagnose the target vehicle and the vehicle system related to the target function or target component according to the vehicle diagnostic module.

[0073] Specifically, when the user selects the diagnostic mode, the diagnostic device diagnoses the part according to the diagnostic module determined by the VIN. For example, after the diagnostic module is determined, the vehicle is systematically and comprehensively diagnosed according to the diagnostic module, which can mainly focus on the faulty parts.

[0074] Step S306: Determine a function guidance program matching the target function or the target component according to the one or more second information.

[0075] Specifically, according to the acquired second information (such as the model or name of a certain component of the vehicle), the corresponding usage guide of the component in the vehicle is determined. The vehicle usage service is a vehicle function guide service. For example, for a certain function of the vehicle, a specific, detailed and operational function operation guide is provided, which is consistent with the specific situation of the vehicle and can even realize fool-proof teaching.

[0076] Step S307: According to the function guidance program, instruct the corresponding function usage process in the target vehicle.

[0077] Specifically, when the user chooses to use the component, a corresponding usage guidance program is provided to guide the user to use the component correctly through certain steps. For example, based on a certain function of the vehicle, the functional usage instructions corresponding to the vehicle function are provided. For example, after determining the start function through the VIN, the vehicle components, structures, and detailed steps and precautions for how to start the vehicle involved in the start function are fed back to the user to help the user apply and solve common problems. For example, after the user buys a new car, if he is unfamiliar with the special functions of the car and it is difficult to actually operate it only by relying on the manual, the user can be guided step by step to use and familiarize himself with it by obtaining the corresponding example demonstration of the function.

[0078] Step S308: During the process of the vehicle using the service, the process information of the vehicle using the service is recorded and the third information is collected.

[0079] Specifically, after the diagnostic device obtains the VIN, it can start recording the process content of applying the VIN on the diagnostic device, such as obtaining the corresponding diagnostic module based on the VIN, or obtaining the instructions for a certain function. Among them, the third information is used to update the first information. In particular, when the information that the VIN can provide does not match the actual needs of the user (for example, the user needs the diagnostic module corresponding to component A, but the diagnostic module cannot be provided based on the VIN), then when the user diagnoses by himself or obtains the corresponding diagnostic module through other means and completes the diagnosis, the diagnostic device can record the process information and transmit it back to the database to further enrich the content of the database.

[0080] Optionally, after the information stored in the database corresponding to the VIN reaches a certain level of richness, an optional functional diagnosis or function guidance menu can be provided to the user after the diagnostic device recognizes the VIN; wherein the content in the menu may involve various known vehicle structures and functions of the target vehicle, and can provide corresponding usage services for the user.

[0081] For example, when a vehicle is being diagnosed, the vehicle diagnostic device is connected to the vehicle and can obtain relevant information about the vehicle based on the vehicle's VIN and provide the user with various information about the vehicle. When the user selects a certain part of the vehicle or a certain function of the vehicle, the diagnostic device selects the vehicle information related to the function or the part from the obtained relevant information according to the user's selection.

[0082] When the diagnostic device cannot provide the information required by the user or cannot match the corresponding diagnostic module, the user will be provided with corresponding reminders, such as "matching failed" or "unable to match", etc., and the process of the diagnostic service and related important details will be recorded. For example, if the user cannot obtain the corresponding diagnostic service from this diagnostic device, the diagnostic device will record the diagnostic part, vehicle information, date and other service information involved in this diagnostic process, and then feed it back to the server where the database is located. For another example, although the user cannot obtain services from this diagnostic device, the diagnosis of the vehicle is completed based on other methods or means. Under the premise of effective connection with the vehicle, the diagnostic device obtains the process and various parameters of the diagnostic service performed by other means, collects and organizes them, and adds them to the database related to the VIN.

[0083] In the case where the diagnostic device can provide a diagnostic module that matches the vehicle, a diagnostic module that is suitable for the vehicle is provided based on the data information obtained based on the VIN; it is understandable that different diagnostic devices may be connected to different databases based on the same VIN; the diagnostic module provided by the diagnostic device may differ from the specific vehicle details of the vehicle. In the case where the diagnostic module and the vehicle cannot be fully matched, the diagnostic device will record the service throughout the entire process of the diagnostic service provided, and for the part that is not suitable or does not match the vehicle, the specific situation of the incompatibility or incompatibility with the vehicle will be recorded and then uploaded to the associated database.

[0084] Step S309: Upload the process information and the third information to the one or more databases to update and / or supplement the first information in the one or more databases.

[0085] Specifically, after recording the process information, the diagnostic device can feed back the content of the process information and the corresponding VIN to the server where the database is located, so that the data related to the VIN stored in the database can be updated in time. Alternatively, the diagnostic device uploads the recorded information to the database while recording the process information. For example, after determining the VIN of the vehicle, an introduction to the use of a certain function of the vehicle is provided according to the needs of the user. For the needs raised by the user, if the query in the database is unsuccessful, start recording the needs. In particular, when the user obtains the use process of a certain function through other means, the use process is recorded and transmitted back to the database. This kind of update operation is conducive to timely feedback and provision in the event that there is a demand for the same service in the future.

[0086] Optionally, the database can be run on a server or a device with similar computing functions. For example, the diagnostic device can store part or all of the first information; when the diagnostic device cannot be connected to the Internet or is used offline, it can match and filter information based on the first information stored in itself and the identified VIN.

[0087] Optionally, during the process of the vehicle using the service, the user's operation behavior and operation content may be recorded in real time, or may be recorded at a certain frequency. This embodiment of the present invention does not limit this.

[0088] Optionally, each time a service situation of a corresponding vehicle is provided based on the vehicle identification number, a relatively detailed record will be made. For a service situation that cannot be provided temporarily, the existing data results can also be classified to form a relatively suitable new database for the user to call. For example, if the function S required by the user does not exist in the database associated with the vehicle, the diagnostic device can search for a functional module with a high similarity or high matching degree with the required function S from the associated database for the user to call or to be improved later.

[0089] Further optionally, when the diagnostic device cannot provide the required functions or modules, the functions or modules required by the user can be searched and obtained through the network. The existing data can also be classified and combined according to the user's specified needs to develop personalized functional services for different users. For example, the user owns an Audi A4 or the user often uses the diagnostic device to perform vehicle diagnosis on the Audi A4. Under the aforementioned conditions, the diagnostic device can store the user's usage records. The diagnostic device can also provide the user with common diagnostic services or service usage instructions for the vehicle (such as the aforementioned Audi A4). The diagnostic device can also form a database strongly related to the vehicle's VIN based on the user's choice or preference; wherein the information stored in the database can be selected and deleted by the user according to actual needs.

[0090] In an embodiment of the present invention, a VIN is obtained and one or more first information matching the vehicle is obtained based on the VIN; wherein the first information may include vehicle body type, vehicle model series, and manufacturer, etc. The required second information is then determined from the first information; based on the second information, accurate vehicle service items can be provided to the user. For example, during vehicle diagnosis, all vehicle information about vehicle A is obtained based on the VIN of vehicle A; based on the components targeted by the diagnosis (such as the engine), various parameters such as the engine model are determined to match the most appropriate diagnostic module, so as to facilitate subsequent diagnosis. By implementing an embodiment of the present invention, the VIN of the vehicle can be effectively used to obtain corresponding vehicle information, improve the efficiency of subsequent vehicle information use, and improve the user experience.
