[0003] Existing intelligent diagnostic software usually contains a large number of menu options and complex function settings, which makes it easy for users to get lost during operation and difficult to find the required diagnostic functions quickly and accurately. In addition, due to the complexity of the diagnostic software menu, the intelligent diagnostic system often finds it difficult to give accurate diagnostic results when dealing with certain complex or rare faults, resulting in misdiagnosis or missed diagnosis.

[0004] Currently, when diagnosing automobile faults, intelligent diagnostic systems usually require users to input a large amount of data, such as vehicle model, year, fault code, etc., and cannot provide a one-step diagnostic solution. Although this form of interaction helps improve the accuracy of diagnosis, it also increases the difficulty of user operation, making the intelligent diagnostic process less "intelligent".

[0005] The above contents are only used to assist in understanding the technical solution of the present application and do not constitute an admission that the above contents are prior art. Summary of the invention

[0069] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0070] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0071] Since the prior art automobile diagnosis process usually requires the input of a large amount of data to improve accuracy, it is impossible to implement a one-step diagnosis solution.

[0072] The present application provides a solution, which identifies vehicle fault information through a pre-built diagnostic model; generates a diagnostic solution based on the vehicle fault information and ranks the popularity of the diagnostic solution; polls the popularity ranking of the diagnostic solution to determine whether the currently displayed diagnostic solution meets expectations; if the currently displayed diagnostic solution meets expectations, the currently displayed diagnostic solution is confirmed as the final diagnostic solution; otherwise, the matching parameters of the diagnostic solution are obtained by guiding real-time input information to update the popularity ranking of the diagnostic solution until it is confirmed as the final diagnostic solution. The present application identifies and diagnoses vehicle faults through a pre-built diagnostic model and polls the popularity ranking of diagnostic solutions. The diagnostic solution can be quickly found without additional input information. When the final diagnostic solution does not exist, the user's real-time input information is used to implement diagnostic model iteration and dynamic update of solution popularity ranking until the currently displayed diagnostic solution that meets expectations is confirmed as the final diagnostic solution.

[0073] Based on this, the present application embodiment provides an intelligent diagnosis method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the intelligent diagnosis method of the present application.

[0074] In this embodiment, the intelligent diagnosis method includes steps S10 to S50:

[0075] Step S10, identifying vehicle fault information through a pre-built diagnostic model;

[0076] It should be noted that the vehicle fault information at least includes fault code, vehicle model and year, historical diagnostic data, sensor readings, vehicle performance data, etc.; the collected vehicle fault information is cleaned, formatted and standardized, and features related to fault diagnosis are extracted from the pre-processed data, such as combinations of fault codes, abnormal patterns of sensor readings, etc.; the pre-built diagnostic model operation adopts machine learning algorithms such as decision trees, support vector machines, neural networks, etc. for training.

[0077] Specifically, the newly collected vehicle fault information is input into a pre-built diagnostic model, and the diagnostic model outputs possible fault types and diagnostic suggestions based on the input data.

[0078] Step S20, generating a diagnosis plan according to the vehicle fault information and ranking the popularity of the diagnosis plan;

[0079] It should be noted that a series of possible diagnostic schemes are generated based on vehicle fault information using a diagnostic knowledge base and an algorithm, and each diagnostic scheme includes at least a fault description, a fault cause, recommended inspection steps, and maintenance suggestions. The popularity ranking of the diagnostic schemes is based on the evaluation results of the generated diagnostic schemes, and the popularity value of each diagnostic scheme is calculated, such as the matching degree of the fault code, the number of times the diagnostic scheme is adopted, and the success rate, etc. The diagnostic schemes are sorted according to the popularity values ​​to form a popularity ranking, and the ranking results are displayed to users, with diagnostic schemes with high popularity being ranked first.

[0080] Step S30, polling the popularity ranking of the diagnostic scheme to determine whether the currently displayed diagnostic scheme meets expectations;

[0081] It should be noted that polling the popularity ranking of the diagnostic solutions means that the system displays the generated diagnostic solutions to the user according to the popularity values ​​from high to low, and judges whether the currently displayed diagnostic solution meets expectations by checking the detailed information of the currently displayed diagnostic solution, including fault description, fault cause, recommended inspection steps and maintenance suggestions. If it does not meet expectations, the next diagnostic solution is polled according to the popularity ranking and the above steps are repeated.

[0082] Step S40, if the currently displayed diagnostic solution meets expectations, confirm the currently displayed diagnostic solution as the final diagnostic solution;

[0083] It should be noted that the user can evaluate the currently displayed diagnostic plan. If he believes that the diagnostic plan is reasonable and consistent with the actual fault condition of the vehicle, he can confirm it through the user interface. The system will record the diagnostic plan confirmed by the user as the final diagnostic plan. The confirmation can be completed by clicking a button, selecting an option, voice command or other interactive methods.

[0084] Step S50, if the currently displayed diagnostic solution does not meet expectations, then obtain matching parameters of the diagnostic solution by guiding real-time input information to update the popularity ranking of the diagnostic solution, until the currently displayed diagnostic solution that meets expectations is confirmed as the final diagnostic solution.

[0085] It should be noted that if the currently displayed diagnostic solution does not meet expectations, the system may guide the user to provide additional information through the user interface to help more accurately diagnose the vehicle fault. The guidance may include asking questions, providing input fields or options, entering voice commands, etc.; at the same time, the system uses the additional information provided by the user to update the matching parameters of the diagnostic solution, and the matching parameters may include fault code matching, vehicle and year correlation, historical success count, etc.; a series of diagnostic solutions and diagnostic solution popularity rankings are regenerated based on the updated matching parameters; the system will continue to rotate the updated diagnostic solution popularity rankings and determine whether the displayed new diagnostic solution meets expectations.

[0086] The present application identifies vehicle fault information through a pre-built diagnostic model; generates a diagnostic solution based on the vehicle fault information and ranks the popularity of the diagnostic solution; polls the popularity ranking of the diagnostic solution to determine whether the currently displayed diagnostic solution meets expectations; if the currently displayed diagnostic solution meets expectations, the currently displayed diagnostic solution is confirmed as the final diagnostic solution; otherwise, the matching parameters of the diagnostic solution are obtained by guiding real-time input information to update the popularity ranking of the diagnostic solution until it is confirmed as the final diagnostic solution. The present application identifies and diagnoses vehicle faults through a pre-built diagnostic model and polls the popularity ranking of the diagnostic solution, solving the technical problem that a large amount of data is usually required to be input in the process of automobile diagnosis to improve accuracy, and the diagnostic solution cannot be implemented in one step. Compared with the prior art, the diagnostic solution can be quickly found without additional input information. When there is no final diagnostic solution, the user's real-time input information is used to implement the iteration of the diagnostic model and the dynamic update of the solution popularity ranking until the currently displayed diagnostic solution that meets expectations is confirmed as the final diagnostic solution.

[0087] Based on this, the present application embodiment provides an intelligent diagnosis method, referring to Figure 2 , Figure 2 This is a flow chart of the second embodiment of the intelligent diagnosis method of the present application.

[0088] In this embodiment, the construction of the pre-constructed diagnostic model includes steps A101 to A107:

[0089] Step A101, collecting historical diagnostic data, maintenance cases and user input information to clean and format the data;

[0090] It should be noted that the historical diagnostic data may come from vehicle maintenance records, fault code databases, etc.; the maintenance cases may include vehicle successful maintenance records, troubleshooting processes, etc.; the user input information may come from user feedback, etc.; data cleaning includes removing irrelevant data, erroneous data, duplicate data, etc.; formatting data may include data conversion, standardization, normalization, etc., so that the data meets the requirements of the diagnostic model.

[0091] Step A102, using machine learning technology to analyze data and extract features;

[0092] It should be noted that the features include at least fault codes and their combinations, sensor readings, and user-described symptoms to reduce the dimension of the data. Cross-validation techniques can also be used to verify the importance of the extracted features to the diagnostic model.

[0093] Step A103, constructing an initial diagnosis model through a machine learning algorithm;

[0094] It should be noted that the machine learning algorithm includes at least a decision tree, a support vector machine, and a neural network.

[0095] Step A104, using the labeled training data set to perform initial diagnosis model training;

[0096] Step A105, verifying and testing the initial diagnosis model through a verification set and a test set;

[0097] It should be noted that a part of the cleaned and formatted data is selected as the training data set, where the labeled data set means that each data sample has a corresponding label or target variable, such as fault category, maintenance suggestion, etc.; the training data set is divided into smaller subsets, such as training set, validation set and test set. The training set is used to train the model, the validation set is used to adjust the model parameters, and the test set is used to evaluate the model performance.

[0098] Step A106, designing a user interface to input user information;

[0099] It should be noted that the system analyzes the needs and expectations of users, determines what information the user interface needs to collect, designs multiple interaction methods, such as clicking, input, interaction, etc., and provides clear guidance and feedback to help users enter information correctly.

[0100] Step A107, iteratively updating the initial diagnosis model according to the user input information and the new diagnosis scheme to obtain a diagnosis model.

[0101] It should be noted that the system integrates user input information and new diagnostic schemes into the existing test set, uses the integrated data set to retrain the diagnostic model, adjusts and optimizes the diagnostic model parameters, performs iterative updates, and improves the accuracy and adaptability of the diagnostic model.

[0102] Further, refer to Figure 3 The third embodiment of the intelligent diagnosis method of the present application provides a flow chart based on the above Figure 3 In the embodiment shown, the "identifying vehicle fault information by using a pre-built diagnostic model" in step S10 is further refined to include steps A301 to A303:

[0103] Step A301, preprocessing the vehicle fault information to extract key features related to diagnosis;

[0104] It should be noted that the data preprocessing includes at least data cleaning and data conversion, so as to convert the vehicle fault information into a format suitable for diagnosis model processing; the key features include at least fault codes, sensor readings, and diagnostic routes.

[0105] Step A302, inputting the key features into a pre-built diagnostic model;

[0106] It should be noted that the key features may be further subjected to feature scaling and feature encoding processing to improve the accuracy of the diagnosis model.

[0107] Step A303, obtaining necessary matching parameters of the diagnosis scheme according to the input key features and the preset algorithm.

[0108] It should be noted that the necessary matching parameters may include fault code, fault category, fault probability, confidence level, etc.

[0109] Specifically, fault information is collected through the vehicle's electronic control unit (ECU) or other data sources, cleaned and formatted, and input into the loaded diagnostic model. Key features related to fault diagnosis are extracted from the preprocessed data, and the input features are processed using the preset algorithm in the diagnostic model to calculate the necessary matching parameter fault codes for the diagnostic solution.

[0110] This embodiment pre-processes the vehicle fault information and inputs it into the loaded diagnostic model to extract key features for matching to obtain necessary matching parameters, which can improve the accuracy and efficiency of diagnosis and facilitate the generation of subsequent diagnostic solutions.

[0111] Further, refer to Figure 4 The fourth embodiment of the intelligent diagnosis method of the present application provides a flow chart based on the above Figure 4In the embodiment shown, the step S20 of "generating a diagnosis plan according to the vehicle fault information and ranking the popularity of the diagnosis plan" is further refined to include steps A401 to A404:

[0112] Step A401, matching the necessary matching parameters with preset matching parameters in the knowledge base;

[0113] It should be noted that the knowledge base may include fault codes, historical fault cases, fault types, etc.

[0114] Step A402, generating a set of diagnostic solutions according to the matching results of the necessary matching parameters;

[0115] It should be noted that each diagnostic solution may include the cause of the fault, maintenance suggestions, maintenance routes, etc.

[0116] Step A403, calculating the heat of the diagnostic scheme by using the heat ranking parameters of the diagnostic scheme, and generating the heat ranking of the diagnostic scheme;

[0117] It should be noted that the popularity ranking parameters at least include the number of times adopted, failure probability, historical maintenance records, etc.

[0118] Step A404, arranging the most popular diagnostic solution at the front of the popularity ranking for user display.

[0119] Specifically, the necessary matching parameters are extracted from the vehicle fault information as fault codes through the diagnostic model, and the fault codes are matched with the preset matching parameters in the knowledge base. A group of 5 possible diagnostic schemes are generated according to the matching results, and the popularity of each diagnostic scheme is obtained by calculating the number of times based on the popularity ranking parameters of the diagnostic scheme. The diagnostic scheme with the highest popularity is ranked at the top of the popularity ranking for user display and selection, helping users to quickly identify the most likely fault causes and solutions.

[0120] This embodiment ensures that the generated diagnostic scheme is highly relevant to the vehicle fault information through necessary matching parameters and preset matching parameters in the knowledge base, and quickly generates a set of diagnostic schemes based on the matching results, thereby reducing the time and labor cost of manual analysis of fault information. The generated diagnostic schemes are ranked based on popularity, which reflects the credibility and priority of the generated diagnostic schemes, helping users to quickly identify and select the most popular and effective diagnostic schemes and reduce waiting time.

[0121] Further, refer to Figure 5 The fifth embodiment of the intelligent diagnosis method of the present application provides a flow chart based on the above Figure 5In the embodiment shown, the step S30 of "polling the popularity ranking of the diagnostic scheme to determine whether the currently displayed diagnostic scheme meets expectations" is further refined, including steps A501 to A505:

[0122] Step A501, displaying the top diagnostic solutions in the popularity ranking to the user;

[0123] It should be noted that the display interface may include elements such as icons, lists, indicator lights, etc., which intuitively display the popularity of the diagnostic solution and related information.

[0124] Step A502, determining whether the currently displayed diagnostic solution meets expectations;

[0125] It should be noted that user feedback on the currently displayed diagnostic solution is collected through the user interface, and the feedback includes user selections, evaluations, questions, etc.; based on the nature of the diagnostic problem and user needs, standards are set to determine whether the diagnostic solution meets expectations, and the standards include the accuracy, feasibility, cost, etc. of the diagnostic solution; the collected user feedback is compared with the set expected standards, and based on the comparison results, a judgment is made and output as to whether the currently displayed diagnostic solution meets expectations.

[0126] Step A503: If the result meets expectations, the currently displayed diagnostic solution is displayed continuously, and the currently displayed diagnostic solution is confirmed as the final diagnostic solution; otherwise, the solution is iterated according to the popularity ranking, and the next diagnostic solution is displayed;

[0127] Step A504, by polling the user review results of each displayed diagnostic solution at a preset time, determining whether the iteratively displayed diagnostic solution meets expectations;

[0128] It should be noted that the user review results of the currently displayed diagnostic plan within a preset time are obtained. The user review results may include user selections, evaluations, questions, etc., and whether the currently displayed diagnostic plan meets expectations is judged based on the user review results. If it does not meet expectations, the next diagnostic plan is displayed in turn based on the popularity ranking, and whether it meets expectations is continued to be judged. The diagnostic plans are polled until no generated diagnostic plan meets expectations.

[0129] Step A505, if the iteratively displayed diagnostic solution does not meet expectations, the matching parameters of the diagnostic solution are obtained through real-time user input information to update the popularity ranking of the diagnostic solution until the iteratively displayed diagnostic solution is confirmed as the final diagnostic solution; otherwise, it is directly confirmed as the final diagnostic solution.

[0130] It should be noted that, based on user feedback and preset expected standards, if the diagnostic solution displayed in the current iteration does not meet expectations, and the diagnostic solutions displayed in the polling do not meet expectations, the user is guided to input information in real time, and the input information may include vehicle model, maintenance history, vehicle usage, etc.; based on the information input by the user in real time, the supplementary matching parameters of the diagnostic solution are obtained, and a set of diagnostic solutions are updated based on the necessary matching parameters and the supplementary matching parameters, and the popularity ranking of the updated diagnostic solution is recalculated; based on the updated popularity ranking, the next diagnostic solution is selected to continue displaying; if the iteratively displayed diagnostic solution meets expectations, it is confirmed as the final diagnostic solution. If the diagnostic solution after the polling display update iteration still does not meet expectations, the user is guided to input information again to update the iterative diagnostic solution and the popularity ranking until the final diagnostic solution is confirmed.

[0131] This embodiment determines whether the currently displayed diagnostic scheme meets expectations by polling the popularity ranking of the diagnostic schemes, wherein polling the popularity ranking of the diagnostic schemes improves the accuracy and efficiency of diagnosis by preferentially displaying the most likely diagnostic schemes; users can directly participate in the diagnostic process by inputting information and reviewing diagnostic schemes in real time, which helps to quickly locate the cause of the fault and improve user participation and satisfaction.

[0132] Further, refer to Figure 6 The fifth embodiment of the intelligent diagnosis method of the present application provides a flow chart based on the above Figure 6 In the embodiment shown, the step S50 of "obtaining matching parameters of the diagnostic scheme by guiding real-time input information to update the popularity ranking of the diagnostic scheme" is further refined, including steps A601 to A604:

[0133] Step A601, displaying a description of a problem and possible options related to the current diagnosis through a user interface;

[0134] It should be noted that the options displayed by the user interface for the user to select may include radio buttons, check boxes, etc.

[0135] Step A602, guiding the user to input information;

[0136] It should be noted that the user interface guides the user to select corresponding options or input relevant information according to the displayed problem description.

[0137] Step A603, obtaining input information provided by the user through the user interface in real time;

[0138] It should be noted that the user interface obtains and displays the information input by the user in real time, and can also be modified.

[0139] Step A604, verifying and confirming the input information.

[0140] It should be noted that the user interface has a confirmation button and a cancel button to confirm the input message or re-enter the message when the input is wrong.

[0141] Specifically, when the user interface displays a description of the problem related to the current diagnosis, for example, "Your vehicle has an engine failure. Please select the following possible symptoms: engine stalling, engine shaking, abnormal engine noise, etc.", the user interface guides the user to input information, such as "Please enter the frequency and duration of the engine shaking, etc." The user interface obtains the user input information in real time: "The user entered the engine shaking frequency as "5 times per minute"", and finally the user interface displays a confirmation button, for example: "Confirm the input information", the user clicks the confirmation button, and the user interface displays confirmation information, such as: "You have successfully entered the engine shaking frequency as 5 times per minute, please wait for the diagnosis result."

[0142] This embodiment guides users to input information by displaying diagnosis-related problem descriptions, obtains user input information in real time, and verifies and confirms the input information; it helps users to more clearly understand the context of the diagnosis and the type of information that needs to be provided, avoids misdiagnosis or missed diagnosis due to incorrect or incomplete information, and helps to update diagnostic models and popularity rankings, thereby providing more accurate diagnostic solutions.

[0144] Step A701, collecting real-time user input information during the diagnosis process through the user interface;

[0145] It should be noted that the user inputs real-time information according to the real-time input prompts during the diagnosis process displayed on the user interface.

[0146] Step A702, processing and analyzing the user's real-time input information to extract key information related to diagnosis;

[0147] It should be noted that natural language processing can be used to identify user input information in real time and extract key information.

[0148] Step A703, obtaining supplementary matching parameters of the diagnosis scheme according to the key information;
