[0002] When a user uses diagnostic equipment to diagnose a vehicle, the system collects the vehicle's data stream for the user to view. The user can also change the display of the vehicle's data stream by viewing all or a portion of it, thereby further determining the vehicle's fault status.

[0003] However, when users use diagnostic equipment to diagnose vehicles, the sheer volume of data streams generated by vehicle systems, coupled with the differences between data streams generated by different vehicle systems, makes it difficult for diagnostic personnel to quickly identify important data streams from a large amount of data, thus affecting the efficiency of vehicle diagnosis.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] To achieve the above objectives, this application proposes a vehicle diagnostic method, which is applied to a diagnostic device and includes:

[0007] Collect vehicle data streams from the vehicle to be diagnosed;

[0008] Based on preset data stream combination display rules, the vehicle data stream is rendered onto the data stream display interface of the diagnostic device for data display, so that diagnostic personnel can diagnose the vehicle to be diagnosed based on the displayed target data stream.

[0019] In one embodiment, the step of determining the data stream type of the plurality of vehicles based on the fault statistical analysis results includes:

[0020] Based on the aforementioned fault statistical analysis results, the fault rate is obtained;

[0021] If the failure rate reaches a preset failure rate threshold, then the data stream type corresponding to the vehicle is determined to be a critical data stream type.

[0022] If the failure rate does not reach the preset failure rate threshold, the data stream type corresponding to the vehicle is determined to be a non-critical data stream type.

[0023] In one embodiment, the data stream display interface includes at least a graphical display area and a list display area.

[0024] The step of rendering the vehicle data stream to the data stream display interface of the diagnostic device based on preset data stream combination display rules for data display, so that diagnostic personnel can diagnose the vehicle to be diagnosed according to the displayed target data stream, includes:

[0025] Based on the vehicle data stream and the vehicle information of the vehicle to be diagnosed, obtain the vehicle key data stream and the vehicle non-key data stream.

[0026] The vehicle's critical data stream is rendered into the graphics display area for graphical data display, and the vehicle's non-critical data stream is rendered into the list display area for list data display, so that diagnostic personnel can diagnose the vehicle to be diagnosed based on the displayed target data stream.

[0027] In one embodiment, prior to the step of rendering the vehicle's critical data stream onto the graphics display area for graphical data display and rendering the vehicle's non-critical data stream onto the list display area for list data display, so that diagnostic personnel can diagnose the vehicle to be diagnosed based on the displayed target data stream, the method further includes:

[0032] The combined display module is used to render the vehicle data stream to the data stream display interface of the diagnostic device based on preset data stream combined display rules, so that the diagnostic personnel can diagnose the vehicle to be diagnosed according to the displayed target data stream. The data stream combined display rules are constructed based on pre-acquired vehicle information, a list of key data streams and a list of non-key data streams.

[0045] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0047] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of this application embodiment is: to collect vehicle data stream of the vehicle to be diagnosed; and to render the vehicle data stream to the data stream display interface of the diagnostic device for display based on preset data stream combination display rules, so that the diagnostic personnel can diagnose the vehicle to be diagnosed according to the displayed target data stream. The data stream combination display rules are constructed based on pre-acquired vehicle information, a list of key data streams and a list of non-key data streams.

[0049] In existing technologies, when using diagnostic equipment to diagnose a vehicle, all data streams of the system are presented for the user to select before viewing the data streams. Users can choose all or some data streams before viewing them. While experts familiar with the vehicle system know which data streams to select, most people are unclear about which data streams are important for each system. Therefore, how to quickly and conveniently view valuable data streams becomes a problem that needs to be solved.

[0050] This application renders the acquired vehicle data stream of the vehicle to be diagnosed onto the data stream display interface of the diagnostic device through data stream combination display rules, realizing vehicle diagnosis based on data stream combination display. This solves the problem in the prior art where diagnostic personnel cannot quickly identify important vehicle data streams, which affects diagnostic efficiency and improves the efficiency of vehicle diagnosis.

[0051] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or diagnostic device capable of performing the above functions. The following description uses a diagnostic device as an example to illustrate this embodiment and the subsequent embodiments.

[0052] Based on this, embodiments of this application provide a vehicle diagnostic method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the vehicle diagnostic method of this application.

[0053] In this embodiment, the vehicle diagnostic method is applied to a diagnostic device and includes steps S10 to S20:

[0054] Step S10: Collect vehicle data stream of the vehicle to be diagnosed;

[0055] It should be noted that the vehicle to be diagnosed refers to the vehicle that needs to be diagnosed. The vehicle data stream is a streaming data collected by sensors from various components of the vehicle and transmitted to the diagnostic equipment through an interface or bus. The vehicle data stream may include data streams related to the vehicle ECU control module, such as engine control parameters (e.g., engine speed, intake air temperature, intake air pressure, oil pressure, coolant temperature, outlet temperature, etc.), powertrain control parameters (e.g., fuel pressure, fuel injection quantity, shift status, clutch status, etc.), and transmission control parameters (e.g., transmission oil temperature, transmission pressure, etc.).

[0056] Step S20: Based on preset data stream combination display rules, the vehicle data stream is rendered to the data stream display interface of the diagnostic device for data display, so that the diagnostic personnel can diagnose the vehicle to be diagnosed according to the displayed target data stream. The data stream combination display rules are constructed based on pre-acquired vehicle information, a list of key data streams, and a list of non-key data streams.

[0057] It should be noted that the data stream combination display rules are constructed based on pre-acquired vehicle information, a list of key data streams, and a list of non-key data streams. These rules determine how to present the vehicle data streams on the diagnostic device interface. Rendering refers to presenting the vehicle data streams on the display interface in a specific manner.

[0058] Understandably, based on the pre-set data stream combination display rules, the collected vehicle data stream is displayed on the interface of the diagnostic equipment in an appropriate manner, enabling diagnostic personnel to clearly observe key vehicle data. This solves the problems of chaotic data display and difficulty in quick location in traditional diagnostic equipment, and helps diagnostic personnel to more accurately locate vehicle problems and shorten troubleshooting time.

[0059] In one possible implementation, steps S21 to S24 may be included before step S20:

[0060] Step S21: Obtain vehicle information for several vehicles;

[0061] It should be noted that the vehicle information may include one or more basic vehicle information related to the vehicle, such as unique identifier, vehicle model, engine type, and sensor type.

[0062] Step S22: Based on the vehicle information, determine the data stream type of the plurality of vehicles, wherein the data stream type includes critical data stream type and non-critical data stream type;

[0063] It should be noted that the data stream type refers to the data stream of vehicle operation. In addition to data stream types that are important for vehicle diagnosis, such as data stream types directly related to vehicle performance and safety, or data stream types that have a high incidence of faults or a high degree of impact on the vehicle (such as engine speed, vehicle speed, etc.), it can also include secondary data stream types in vehicle diagnosis, such as data stream types related to vehicle comfort and entertainment, or data stream types that have a low incidence of faults or a low degree of impact on the vehicle (such as air conditioning status, audio volume, etc.).

[0064] Understandably, based on the acquired vehicle information, the key data stream type and non-key data stream type corresponding to each vehicle are determined, which serves as the basis for classifying data streams in subsequent steps.

[0065] Step S23: Based on the data stream types corresponding to the vehicles, obtain a list of critical data streams and a list of non-critical data streams;

[0066] It should be noted that the critical data flow list refers to a list that summarizes the critical data flow types across all vehicles. The non-critical data flow list refers to a list that summarizes the non-critical data flow types across all vehicles.

[0067] Understandably, the key data flow list and non-key data flow list for each vehicle are obtained from the data flow type corresponding to each vehicle, providing the basis for constructing data flow display rules for subsequent steps.

[0068] Step S24: Based on the vehicle information, the list of key data streams, and the list of non-key data streams, a data stream combination display rule is constructed.

[0069] It should be noted that the data stream combination display rule refers to the rule for determining the key and non-key data streams of the vehicle based on the vehicle information, and determining how different data stream types are combined and displayed on the diagnostic device interface.

[0070] Understandably, based on the vehicle information and the integrated list of key and non-key data streams, data stream combination display rules are constructed to determine how to present the vehicle data stream on the diagnostic device's interface, ensuring that the diagnostic device can clearly and reasonably display the vehicle data stream, enabling diagnostic personnel to accurately observe and analyze the vehicle's status.

[0071] In this embodiment, by comprehensively considering vehicle information and data stream types, integrating data stream types from multiple vehicles, and formulating comprehensive and systematic data stream combination display rules, the diagnostic equipment can clearly and reasonably display vehicle data streams, better adapt to the diagnostic needs of different vehicles, ensure that the diagnostic equipment can accurately present important data streams, solve the problem of chaotic and inconsistent data display on the diagnostic equipment interface, and help diagnostic personnel improve diagnostic efficiency and accuracy.

[0072] In one feasible implementation, the vehicle information includes at least vehicle model information and system information, and step S22 may include steps S221 to S223:

[0073] Step S221: Obtain vehicle fault diagnosis records based on the vehicle model information and system information of the aforementioned vehicles;

[0074] It should be noted that the vehicle model information refers to basic information such as the vehicle's brand and model. The system information refers to information about various vehicle systems, such as the engine control system and braking system. The fault diagnosis record refers to the record of historical fault diagnosis information of the vehicle stored in diagnostic equipment or a database.

[0075] Understandably, by extracting relevant data from the vehicle's fault diagnosis records based on vehicle model information and system information, including fault codes and sensor data, we can understand the historical fault situation of the vehicle or the corresponding model and provide data support for subsequent fault analysis.

[0076] Step S222: Perform statistical analysis on the vehicle fault diagnosis records to obtain fault statistical analysis results;

[0077] Understandably, the aim is to discover the extent to which vehicle malfunctions affect data streams. By conducting statistical analysis on vehicle malfunction diagnostic records, the statistical analysis results can be obtained, which can identify the influencing factors related to common malfunction data streams and provide a basis for determining critical and non-critical data stream types.

[0078] Step S223: Determine the data stream type of the plurality of vehicles based on the fault statistical analysis results.

[0079] It should be noted that the data stream types can include critical data stream types and non-critical data stream types. Critical data stream types refer to data stream types within the vehicle's data stream that are associated with known faults, and can characterize data stream types that indicate or represent the precursors to vehicle faults. Non-critical data stream types refer to data stream types within the vehicle's data stream that are not directly related to known fault types or frequencies, and can represent general vehicle operating data.

[0080] Understandably, determining the data stream type for each vehicle based on the statistical analysis of vehicle fault diagnosis records helps to classify and distinguish data streams of different importance in different vehicles.

[0081] In this embodiment, the vehicle's historical fault diagnosis records are used to determine the fault patterns and trends through statistical analysis, thereby enabling more accurate data stream classification and rule formulation, and improving the accuracy of key data display.

[0082] In one feasible implementation, step S223 may include steps S2231 to S2233:

[0083] Step S2231: Obtain the failure rate based on the fault statistical analysis results;

[0084] It is understood that the aforementioned fault statistical analysis results refer to the results obtained through statistical analysis of vehicle faults, including the frequency of various fault types that may occur in different vehicles, such as engine faults and braking system faults. The fault rate refers to the frequency of a certain type of fault occurring within a certain period of time or in different vehicle models, and can be expressed in the form of time frequency or percentage.

[0085] Step S2232: If the failure rate reaches a preset failure rate threshold, then the data stream type corresponding to the vehicle is determined to be a critical data stream type.

[0086] It is understood that the preset failure rate threshold is a set threshold used to determine whether the failure rate has reached a critical level. The critical data stream type refers to data stream types closely related to vehicle failures, which may include information such as fault detection and early warning. The non-critical data stream type refers to data stream types related to general vehicle operation data, which may include information such as daily operating status and performance parameters.

[0087] It should be noted that if the failure rate reaches the preset failure rate threshold, the data stream type corresponding to the vehicle can be determined as a critical data stream type.

[0088] Step S2233: If the failure rate does not reach the preset failure rate threshold, then the data stream type corresponding to the vehicle is determined to be a non-critical data stream type.

[0089] It should be noted that if the failure rate corresponding to the vehicle fault type does not reach the preset failure rate threshold, then the data stream type corresponding to the vehicle can be determined to be a non-critical data stream type.

[0090] In this embodiment, based on the fault types and fault rates obtained from the statistical analysis of vehicle fault diagnosis records, the data stream types whose fault rates reach a preset fault rate threshold are identified as critical data stream types, and those whose fault rates do not reach a preset fault rate threshold are identified as non-critical data stream types. By managing critical and non-critical data streams, targeted data analysis and display processing can be performed.

[0091] This embodiment provides a vehicle diagnostic method that renders the acquired vehicle data stream of the vehicle to be diagnosed onto the data stream display interface of the diagnostic device through data stream combination display rules. This realizes vehicle diagnosis based on data stream combination display, solves the problem in the prior art that diagnostic personnel cannot quickly identify important vehicle data streams, which affects diagnostic efficiency, and improves the efficiency of vehicle diagnosis.

[0092] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the vehicle diagnostic method of this application.

[0093] In this embodiment, the data stream display interface includes at least a graphical display area and a list display area, and step S20 may include steps S201 to S202:

[0094] Step S201: Based on the vehicle data stream and the vehicle information of the vehicle to be diagnosed, obtain the vehicle key data stream and the vehicle non-key data stream.

[0095] Understandably, under the data stream combination display rules, the key data stream type and non-key data stream type of the vehicle to be diagnosed are determined based on the vehicle information of the vehicle to be diagnosed, thereby dividing the vehicle data stream into vehicle key data stream and vehicle non-key data stream.

[0096] Step S202: The vehicle key data stream is rendered to the graphics display area for graphical data display, and the vehicle non-key data stream is rendered to the list display area for list data display, so that diagnostic personnel can diagnose the vehicle to be diagnosed based on the displayed target data stream.

[0097] It should be noted that the graphical data display refers to showcasing the vehicle's key data streams, such as real-time data collected by sensors and fault warning information, in an intuitive graphical format. This allows diagnostic personnel to quickly understand the vehicle's status. Specific graphical display areas may include line graphs, bar charts, dashboards, component diagrams, etc., and can be designed according to the characteristics of the specific key data streams. The list data display refers to displaying the vehicle's non-critical data streams in a list format in the list display area, such as basic vehicle information and performance parameters. This facilitates detailed viewing and comparative analysis by diagnostic personnel. The specific list may include the name, value, or description of each data field, as well as possible operation buttons or filtering functions, and is displayed in a specific order.

[0098] In one possible implementation, steps S2021 to S2022 may be included before step S202:

[0099] Step S2021: Construct component diagrams of the vehicle to be diagnosed based on the vehicle components corresponding to the vehicle key data stream;

[0100] Understandably, based on the components involved in the vehicle's key data flow, a graph of one or more components of the vehicle to be diagnosed is created to display the real-time dynamic changes of each component in the graphical display area. This can intuitively show the position and status of each component of the vehicle to be diagnosed, helping diagnostic personnel to better understand the relationship between the vehicle's component structure and data flow.

[0101] Step S2022: Render the component graphic onto the graphic display area to display the data graphically in conjunction with the vehicle key data stream.

[0102] Understandably, rendering the constructed component graphics into the graphics display area and combining them with the vehicle's key data streams enables graphical data display. By displaying component graphics and data streams together, vehicle status information is presented in a more intuitive and comprehensive way. Diagnostic personnel can simultaneously see the component locations and corresponding data stream information on the graphical interface, which helps them to perform diagnostic analysis more quickly and accurately.

[0103] In this embodiment, data is displayed by combining key data streams and vehicle component graphics, which improves the visualization effect and information display capability of the data display interface. This provides diagnostic personnel with a more comprehensive and intuitive data display environment, helping them to better understand the vehicle's condition and perform diagnostic work.

[0104] In one possible implementation, step A2023 may be included after step S202:

[0105] Step A2023: In response to the button trigger command of the component graphic, stop the rendering of the component graphic and the rendering of the vehicle key data stream, and re-render the vehicle key data stream to the parallel display area for data display.

[0106] Understandably, when a diagnostician clicks on a component graphic in the graphical display area of ​​the data stream display interface, switching the displayed content from component graphic and key data stream to displaying only multiple key data streams side by side allows for flexible switching between component graphic and data stream display, enabling better viewing and analysis of the data stream and improving diagnostic efficiency.

[0107] This implementation provides users with a more flexible operating method, enabling them to select the display of component graphics and key vehicle data streams according to actual needs. This helps users observe and diagnose data according to different stages or situations, improves user experience, and better meets users' personalized needs for data display interfaces.

[0108] For example, such as Figure 3 As shown, Figure 3 This is a schematic diagram illustrating an example of the combined display of data streams in the vehicle diagnostic method described in this application. Based on the importance of the data streams in the vehicle system, a maximum of a certain number of the most important key data streams that need to be viewed can be predefined for each system. These most important data streams are displayed in the corresponding important area of ​​the data stream display interface, which can be displayed using component graphics combined with data. A certain number of common data streams are displayed in the less important area of ​​the interface, which can be displayed as a data list. When the user selects to read a data stream, the most important and common data streams are displayed directly, and a button to read more data streams is provided, allowing the user to select other data streams to read.

[0109] Step S1: The user enters the corresponding vehicle system module in the diagnostic device and selects the data stream reading function;

[0110] Step S2: Read the most important data streams predefined by the module, the graphical diagram of the module, and the fixed parts of the important data streams (data stream name, data stream unit, standard value range, etc.);

[0111] Step S3: Read the module's predefined common data streams (data stream name, data stream unit, standard value range, etc.);

[0112] Step S4: Display the data from steps S2 and S3 on the interface, with the most important data stream being displayed. Figure 3 The right side of the interface displays common data streams. Figure 3 The left side of the interface;

[0113] Step S5: Loop through the values ​​and status (whether they are within the normal range) of the most important data stream and common data streams, and refresh the data stream on the interface.

[0114] Step S6, as follows Figure 4 As shown, Figure 4 This is a schematic diagram illustrating an example of a data stream display interface displaying data streams side-by-side, as described in the vehicle diagnostic method of this application. If a user wishes to view other data streams, they can click on the interface buttons or graphical buttons to select from more data streams provided by the system. After selection, one or more selected data streams will be displayed side-by-side in the data stream display interface.

[0115] Step S7, in Figure 4 In the right-hand graphical display area of ​​the interface, you can select a data stream to view its graph. You can also combine the data streams read from the right-hand area and the data streams from the left-hand list interface for a single view.

[0116] By using data stream combination display rules, the acquired vehicle data stream of the vehicle to be diagnosed is rendered onto the data stream display interface of the diagnostic device, realizing vehicle diagnosis based on data stream combination display. This solves the problem in the existing technology where diagnostic personnel cannot quickly identify important vehicle data streams, which affects diagnostic efficiency and improves the efficiency of vehicle diagnosis.

[0117] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the vehicle diagnostic method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0118] In this embodiment, the key vehicle data stream is rendered to the graphics display area for graphical data display, and the non-key vehicle data stream is rendered to the list display area for list data display. This allows diagnostic personnel to diagnose the vehicle to be diagnosed based on the displayed target data stream, realizing real-time updates and dynamic and static displays of the data stream, ensuring that diagnostic personnel can obtain the latest vehicle data in a timely manner.
