Description

TECHNICAL FIELD

[0001] The present application belongs to the field of user interface of automobile diagnostic equipment, and particularly relates to a display method and device of automobile diagnostic data, an automobile diagnostic equipment and a storage medium. BACKGROUND

[0002] When an operator uses an automobile diagnostic equipment to diagnose a vehicle to be detected, after running diagnostic software, the display mode of diagnostic results is that the page currently displayed on the display screen of the diagnostic equipment only displays diagnostic result data flow of one system.

[0003] If the operator needs to view diagnostic results of multiple systems (such as engine system, transmission system, brake system and other automobile systems) of the automobile detected by the diagnostic equipment, the operator must view each diagnostic data flow one by one on the display screen of the diagnostic equipment to view each diagnostic result, that is, the operator needs to exit the page of the currently displayed system and enter the page of other system to view the corresponding diagnostic result data flow, which will result in poor user experience and affect work efficiency. SUMMARY

[0004] Therefore, the present application provides a display method and device of automobile diagnostic data, an automobile diagnostic equipment and a storage medium to solve the technical problem that the user needs to switch different automobile systems through the diagnostic equipment to view each diagnostic data when the user needs to view different diagnostic data of multiple automobile systems at the same time, which results in poor user experience.

[0026] In one implementation, each of the target diagnostic data stream options in the multi-system data stream area is configured with a delete icon;

[0027] The method further includes:

[0028] In response to receiving a trigger operation on the deleted icon, the target diagnostic data stream option is deleted from the multi-system data stream area.

[0029] In one implementation, before displaying the vehicle system options area in the application interface, the method further includes:

[0048] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0049] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0050] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0051] As used in this application specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if detected [the described condition or event]" may be interpreted, depending on the context, as meaning "once determined," "in response to determination," "once detected [the described condition or event]," or "in response to detection [the described condition or event]."

[0052] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0054] Understandably, in conventional operations of the prior art, when operators (users) use diagnostic equipment to diagnose a vehicle under test, they often need to view different diagnostic data from multiple automotive systems simultaneously. Users must switch between different automotive systems using the diagnostic equipment to view each piece of diagnostic data. How to facilitate users in selecting diagnostic data from multiple different automotive systems is a technical problem that urgently needs to be solved. In this regard, this application provides a method for displaying automotive diagnostic data, which solves the above-mentioned defects of the prior art. Specifically, this application illustrates the technical solution of the present invention through specific embodiments.

[0055] Example 1

[0056] like Figure 1 As shown in the embodiments of this application, the method for displaying automotive diagnostic data is applied to automotive diagnostic equipment, and the method includes:

[0057] Step S10: Display the vehicle system options area in the application interface. The vehicle system options area contains n system options for the vehicle under test, where n is a positive integer.

[0058] Understandably, such as Figure 2 As shown, the vehicle system options area can be a list of system options located on the far left of the application interface;

[0059] In practice, after a user uses a vehicle diagnostic device to inspect the vehicle under test, the vehicle diagnostic device will add the system type names corresponding to the n vehicle ECU systems under test as system options to the vehicle system options area.

[0060] Combination Figure 3 As shown, the n (automotive ECU) systems of the vehicle under test may include the EMS (engine control module) system, BCM (body control module) system, ABC (anti-lock braking system), TCU (transmission control module) system, and SRS (assisted inflatable restraint system).

[0061] Step S20: Upon receiving a trigger operation for the system option, display the diagnostic data area, where m diagnostic data stream options corresponding to the triggered target system option are displayed in the diagnostic data area, where m is a positive integer.

[0062] In practical implementation, the automotive diagnostic equipment acquires diagnostic results related to each system of the vehicle under test, and adds each diagnostic result as a diagnostic data stream option to the diagnostic data area; for example... Figure 2 As shown, each system of the tested vehicle can correspond to m diagnostic results; combined with Figure 3 As shown, for example, the EMS (Engine Control Module) system can correspond to five diagnostic results: "reference voltage", "in-vehicle temperature", "vehicle speed", "idle speed control RPM expected value" and "engine cooling temperature". These five diagnostic results are added to the diagnostic data area as diagnostic data stream options.

[0063] Furthermore, in the user's "vehicle system options area (i.e. Figure 2 and Figure 3 When you select the "EMS (Engine Control Module) System" system option from the system options list on the left side of the application interface (i.e., when the vehicle diagnostic equipment performs a trigger operation), the application interface will immediately display a "diagnostic data area" containing five diagnostic results: "reference voltage," "in-vehicle temperature," "vehicle speed," "idle speed control RPM expected value," and "engine cooling temperature." Figure 2 and Figure 3 (The data flow option list is located in the middle of the application interface).

[0064] Step S30: Upon receiving a trigger operation for the diagnostic data stream option, the triggered target diagnostic data stream option is added to the multi-system data stream area, and the multi-system data stream area containing the target diagnostic data stream option is displayed.

[0065] Understandably, such as Figure 2 As shown, each "Diagnostic Data Stream Option" in the "Multi-System Data Stream Area" is configured with a corresponding "Selection Icon." When a user clicks this "Selection Icon," a checkmark icon appears, indicating that the "Diagnostic Data Stream Option" has been selected (i.e., the diagnostic device triggers an operation on the diagnostic data stream option). The selected "Target Diagnostic Data Stream Option" is then immediately added to the "Multi-System Data Stream Area." Figure 2As shown, after the user "checks" the two "target diagnostic data stream options" in the "diagnostic data area", the "multi-system data stream area" containing the two "target diagnostic data stream options" checked by the user will be displayed on the far right of the application interface. In this way, when the user uses the diagnostic equipment to diagnose the vehicle being tested, he / she can view different diagnostic data of multiple vehicle systems at the same time in a specific application interface of the diagnostic equipment. The user does not need to switch between different vehicle systems through the diagnostic equipment to view each piece of diagnostic data, which helps to improve the efficiency of the user in using the diagnostic equipment to test and repair vehicles.

[0066] For example, a diagnostic indicator of a vehicle's fault manifesting as weak acceleration when the accelerator pedal is pressed might be related to the Engine Control System (EMS) and Transmission Control Unit (TCU) system options. This diagnostic indicator requires analysis of vehicle diagnostic data related to acceleration from the accelerator pedal in both the EMS and TCU systems. Examples include diagnostic data stream options in the EMS system such as accelerator pedal position sensor voltage, fuel injector phase values ​​for each cylinder, oxygen sensor voltage, throttle position data, and engine RPM; and diagnostic data stream options in the TCU system such as clutch sensor data, input shaft speed, and output shaft data. After selecting the target diagnostic data stream option related to vehicle speed acceleration diagnostic indicators from the EMS system and TCU system, the software cyclically reads the selected data streams from each system of the vehicle and refreshes them in the application interface. Ultimately, the user can simultaneously display the target diagnostic data stream option related to vehicle speed acceleration diagnostic indicators selected from the EMS system and TCU system in a specific multi-system data stream area of ​​the diagnostic device application interface through the operation method described in steps S10 to S30 above. The user does not need to switch between the dedicated interfaces of the EMS system and TCU system to view each diagnostic data, thereby improving the user experience.

[0067] Example 2

[0068] Based on the technical solution of Embodiment 1 above, and referring to... Figure 4 The method for displaying vehicle diagnostic data in this second embodiment further includes:

[0069] Sub-step S21: In response to receiving a trigger operation for the first system option, multiple first diagnostic data stream options corresponding to the triggered first system option are displayed in the diagnostic data area;

[0070] Specifically, for example, if the user first selects "EMS System" (first system option) from the "Vehicle System Options Area" list on the left side of the application interface, the "Diagnostic Data Area List" in the middle of the application interface will display multiple first diagnostic data stream options (such as...) corresponding to the triggered "EMS System". Figure 3The system displays the following parameters: "Reference Voltage", "In-Vehicle Temperature", "Vehicle Speed", "Idle Speed ​​Control RPM Expected Value" and "Engine Cooling Temperature".

[0071] Sub-step S31: In response to receiving a trigger operation for the first diagnostic data stream option, add the triggered first target diagnostic data stream option to the multi-system data stream region;

[0072] Step S33: Display the multi-system data stream area containing the first target diagnostic data stream option.

[0073] Specifically, refer to Figure 3 After the user "checks" the "Reference Voltage" first diagnostic data stream option of the EMS system in the "Diagnostic Data Area", the "Reference Voltage" first diagnostic data stream option will be added to the multi-system data stream area. Then, the "Multi-system Data Stream Area" will be displayed on the far right of the application interface, and the "Reference Voltage" first diagnostic data stream option will be displayed in the "Multi-system Data Stream Area".

[0074] Sub-step S22: In response to receiving a trigger operation for the second system option, multiple second diagnostic data stream options corresponding to the triggered second system option are displayed in the diagnostic data area;

[0075] Specifically, users can then select "BCM System" (second system option) from the "Vehicle System Options Area" list on the left side of the application interface. The "Diagnostic Data Area List" in the middle of the application interface will then display multiple second diagnostic data stream options corresponding to the triggered "BCM System". Figure 3 (Not shown, the diagnostic data of the BCM system may specifically include data such as "vehicle battery temperature" and "steering wheel angle sensor" for display.)

[0076] Sub-step S32: In response to receiving a trigger operation for the second diagnostic data stream option, add the triggered second target diagnostic data stream option to the multi-system data stream region;

[0077] Specifically, refer to Figure 3 After the user selects the three second diagnostic data stream options "Battery Voltage", "Vehicle Battery Temperature" and "Steering Wheel Angle Sensor" of the BCM system in the "Diagnostic Data Area", these three second diagnostic data stream options will be added to the multi-system data stream area that has been displayed in step S33. Then the three second diagnostic data stream options "Battery Voltage", "Vehicle Battery Temperature" and "Steering Wheel Angle Sensor" will be displayed in the "Multi-system Data Stream Area".

[0078] Step S33: Display the second target diagnostic data stream option and the first target diagnostic data stream option in the multi-system data stream area.

[0079] Furthermore, in this embodiment, as Figure 3 As shown, the multi-system data stream area also includes a data combination button; the application interface also includes a historical data preview button.

[0080] Following step S33' above, the method further includes:

[0081] Step A1: In response to receiving a trigger operation on the data combination button, combine the first target diagnostic data stream option and the second target diagnostic data stream option to obtain a multi-system data stream;

[0082] It is understandable that the "multi-system data stream" can be understood as the need to combine diagnostic data (diagnostic data streams) from several different automotive systems to form a set of combined data representing the diagnostic indicator when a user needs to know a certain diagnostic indicator of the car.

[0083] For example, the vehicle speed control diagnostic indicator is included in the Engine Control System (EMS) and Transmission Control Unit (TCU). During vehicle diagnostics, if the acceleration of the vehicle under test does not meet expectations after the user presses the accelerator pedal, the user needs to check the relevant diagnostic data (diagnostic data stream option) of the two automotive ECU systems, the EMS system and the TCU system.

[0084] Step A2: Save the multi-system data stream to a preset storage area;

[0085] Step A3: In response to receiving a trigger operation on the historical data preview button, the preset storage area is displayed. The preset storage area contains multi-system data stream options corresponding to the multi-system data stream. The labels of the multi-system data stream options display relevant information such as the generation time of the multi-system data stream, the system option type, and the identification information of the test vehicle.

[0086] In the specific implementation, after the user clicks the "Data Combination Button," the multi-system data stream is saved to a preset storage area, and multi-system data stream options corresponding to the multi-system data stream are generated, such as... Figure 5 As shown, the label of the multi-system data stream option at least displays the generation time and system option type of the multi-system data stream. In other embodiments, the label of the multi-system data stream option may also include the identification information of the test vehicle (e.g., the specific model of the test vehicle, i.e., the diagnostic device can store multi-system data streams of different models of test vehicles).

[0087] When a user wants to view the diagnostic records of the vehicle under test by the diagnostic device, they can click the historical data preview button on the application interface of the diagnostic device. The preset storage area can be randomly displayed on the application interface. In some embodiments, each multi-system data stream option in the preset storage area is configured with an "edit icon" and a "delete icon". The user can click the "edit icon" to modify the label of the selected target multi-system data stream option, and the user can click the "delete icon" to delete the selected target multi-system data stream option from the preset storage area.

[0088] Furthermore, to avoid the technical problem of data not being able to be updated in real time when refreshing the diagnostic data stream due to the potential operational pressure on the diagnostic equipment hardware when users select too much diagnostic data at once, in some embodiments, after the automotive diagnostic equipment tests the vehicle under test, it can pre-set the maximum number of system options supported for the vehicle under test, as well as the maximum number of diagnostic data stream options under each system option, based on the specific circumstances of the vehicle model (model-related data), so as to provide users with the convenience to select multiple system data streams according to their actual needs in the application interface.

[0089] Understandably, due to the need to switch between data streams of different ECU systems, or because some ECU systems have a large number of data streams (some ECU systems have thousands of diagnostic data streams), especially in some non-CAN line (LINE line, or K-line low speed) ECU systems, restrictions are placed on the selection of data streams from multiple different ECU systems in order to ensure the real-time viewing of cross-system data streams.

[0090] In specific implementations, for example, vehicle model A supports packaging and reading vehicle data via the CAN bus, allowing for rapid reading of data from multiple systems and meeting the real-time requirements for data stream viewing. Therefore, this embodiment can set a large value to allow users to arbitrarily select the number of vehicle system options and diagnostic data stream options. On the other hand, for vehicle model K, a single diagnostic data stream option may require multiple commands to interact with the vehicle for reading, and this model does not support packaged data. Without restrictions, selecting a large number of data streams from multiple systems would be extremely time-consuming and would compromise the real-time viewing of multi-system data streams.

[0091] Furthermore, in other embodiments, the diagnostic software of the automotive diagnostic equipment pre-selects important multi-system data stream selection information by default, such as... Figure 3As shown, the bottom of the application interface may also include a "Vehicle Core Data Stream" function button. When the user triggers the "Vehicle Core Data Stream" function button, the vehicle diagnostic equipment can update and display the pre-built multi-system data stream information in the "Multi-System Data Stream Area" interface.

[0094] The first display unit 601 is used to display a vehicle system option area on the application interface. The vehicle system option area contains n system options of the vehicle under test, where n is a positive integer.

[0095] The second display unit 602 is used to display a diagnostic data area when a trigger operation on the system option is received, and to display m diagnostic data stream options corresponding to the triggered target system option in the diagnostic data area, where m is a positive integer;

[0096] The third display unit 603 is configured to add the triggered target diagnostic data stream option to the multi-system data stream area upon receiving a trigger operation for the diagnostic data stream option.
