[0030] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0032] In addition, it should be noted that the acquisition, storage, use, and processing of data in the embodiments of this application are in compliance with the relevant provisions of national laws and regulations. It should be noted that in the embodiments of this application, some existing solutions in the industry such as certain software, components, and models may be mentioned, and they should be considered as exemplary. Their purpose is only to illustrate the feasibility of the implementation of the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0033] In order to solve the problems of the prior art, the embodiments of the present application provide a display control method, device, equipment, medium and program product for an instrument screen. The display control method for an instrument screen provided by the embodiments of the present application is first introduced below.

[0034] Figure 1 FIG. 1 is a flow chart showing a display control method of an instrument screen provided by an embodiment of the present application. Figure 1 As shown, the display control method of the instrument screen may include:

[0035] Step 101, obtaining the display status of the instrument interface on the instrument screen.

[0036] In step 101, a keep-alive program may be set to monitor the display status of the instrument interface on the instrument screen to determine whether the current instrument interface has a display abnormality.

[0037] For example, the display status of the instrument interface on the instrument screen can be obtained, and the display status can be the process running status information of the instrument program. For example, if the process of the instrument program is not running during the vehicle startup process, it can be considered that the instrument interface display is abnormal. The display status can also be a heartbeat signal sent by the instrument program at regular intervals. For example, if the heartbeat signal is not received for a long time, it can be considered that the instrument interface display is abnormal.

[0038] Step 102, when the display status indicates that the instrument interface displays abnormally, a transition page is generated according to the display content of the instrument interface; wherein the display content of the instrument interface and the display content of the transition page include the same display information, and the transition page is configured to prohibit responding to user input.

[0039] In step 102, it is understandable that if the display status indicates that the instrument interface displays abnormally, the instrument interface may be in a stuck state, that is, the display content of the instrument interface can no longer respond to any signal changes, resulting in the user being unable to accurately obtain the vehicle's driving information including speed, gear, battery power, mileage, etc., thereby affecting driving safety. Therefore, it is necessary to restart the instrument interface to restore the normal display. However, during the restart of the instrument interface, since the instrument program is killed and it takes some time to reinitialize, the user may see a black screen on the instrument screen during this period, thereby perceiving that an abnormality has occurred in the instrument program.

[0040] Based on this, when the instrument interface displays abnormally, a transition page can be generated according to the display content of the instrument interface, and the display content of the transition page can include the same display information as the display content of the instrument interface. For example, the display content of the instrument interface can include driving information such as speed, gear, battery power, and cruising range, and can also include entertainment information such as music playback screen and navigation. Correspondingly, the transition page can also include driving information such as speed, gear, battery power, and cruising range, as well as entertainment information such as music playback screen and navigation. And the display position corresponding to the same type of display information in the display content of the instrument interface and the display content of the transition page is also consistent.

[0041] It is understandable that the transition page can be a static page that is configured to prohibit responding to user input. In other words, when the transition page is displayed, it cannot respond to the user's operation of switching the displayed content. For example, if the user inputs an operation of switching cards on the transition page, the transition page will not respond and will still display the original content.

[0042] Step 103: Display a transition page on the instrument screen.

[0043] In step 103, a transition page may be displayed on the instrument screen. Figure 2a As shown, when the instrument interface 202 is displayed normally, the display layer of the instrument screen may include a black screen background 201 at the bottom layer, and the instrument interface 202 located above the black screen background 201. Figure 2b As shown, when the instrument interface 202 displays abnormally, a transition page 203 can be generated. The transition page 203 also serves as a display layer of the instrument screen and is located above the instrument interface 202. At this time, the instrument screen image seen by the user is the transition page 203.

[0044] The display control method, device, equipment, medium and program product of the instrument screen of the embodiment of the present application can obtain the display status of the instrument interface on the instrument screen; when the display status indicates that the instrument interface is abnormal, a transition page is generated according to the display content of the instrument interface; wherein the display content of the instrument interface and the display content of the transition page include the same display information; and the transition page is displayed on the instrument screen. In this way, before the instrument interface is restarted, a transition page with the same display information as the instrument interface with the abnormal display can be generated, that is, the display content of the transition page is highly consistent with the display content of the instrument interface with the abnormal display, so that during the restart of the instrument interface, the user's perception of the abnormality of the instrument program can be reduced by displaying the transition page, thereby reducing the risk of panic and anxiety of the user caused by the abnormality of the instrument program, thereby improving driving safety.

[0045] In some embodiments, after controlling the instrument interface to restart, the method may further include:

[0046] The control instrument interface restarts.

[0047] In this embodiment, when a transition page is displayed on the instrument screen, the instrument interface can be controlled to restart. In other words, the instrument program can be forcibly closed so that the instrument program is killed, and then the instrument program can be started again to complete the initialization of the instrument program, thereby achieving the purpose of restoring the normal display of the instrument interface.

[0048] It is understandable that if Figure 2c As shown, during the restart process, the display layer of the instrument screen may include a black screen background 201 and a transition page 203 located above the black screen background 201, that is, during the restart process, the instrument screen image seen by the user is the transition page 203, and the black screen background 201 will not be directly seen due to the restart of the instrument interface.

[0049] In this way, the user's perception of abnormalities in the instrument program can be reduced, thereby reducing the risk of panic and anxiety caused by abnormalities in the instrument program and improving driving safety.

[0050] In some embodiments, after the control instrument interface is restarted, the method further includes:

[0051] When the restart of the instrument interface is completed, the restarted instrument interface is displayed on the instrument screen, and the transition page is hidden.

[0052] In this embodiment, when the instrument interface is restarted, the instrument interface is displayed normally, that is, the display content in the instrument interface can be updated in time in response to the received signal. Figure 2dAs shown, at this time, the instrument interface 202 after restart can be displayed on the instrument screen, and the transition page 203 is hidden, that is, the picture seen by the user on the instrument screen is the instrument interface 202 after restart.

[0053] In some embodiments, generating a transition page according to the display content of the instrument interface may include:

[0054] The display content of the instrument interface is copied to obtain a transition page, and the display content of the transition page is the same as the display content of the instrument interface.

[0055] In this embodiment, the display content of the instrument interface can be directly copied to obtain a transition page with exactly the same display content. In other words, the transition page can be an image, which can be obtained by taking a screenshot of the instrument interface and displayed on the instrument screen as a transition page.

[0056] In this way, since the transition page is exactly the same as the display content when the instrument interface displays an abnormality, the transition page is displayed during the restart of the instrument interface, and the user will not perceive the process of restarting the instrument interface, thereby reducing the user's perception of abnormal situations in the instrument program, thereby reducing the risk of user panic and anxiety, and improving driving safety.

[0057] In some embodiments, when the display status indicates that the instrument interface is abnormal, a transition page is generated according to the display content of the instrument interface, including:

[0058] When the display status indicator instrument interface displays an abnormality, obtaining the vehicle's driving information, the driving information including at least one of the vehicle speed, gear position, battery power and cruising range;

[0059] Driving information is drawn based on a lightweight graphics engine, and a transition page is generated, and the displayed information includes driving information.

[0060] In this embodiment, the displayed information may include driving information, and the driving information may include at least one of vehicle speed, gear position, battery power, and cruising range.

[0061] When generating a transition page, the vehicle driving information corresponding to that moment can be read and the display content can be drawn that is the same as the instrument interface. In this way, the display content of the transition page can include the vehicle driving information at the time of display, so that the user can obtain the accurate driving status of the vehicle and further improve driving safety.

[0062] In some embodiments, when the displayed information includes driving information and entertainment information, the driving information is drawn based on a lightweight graphics engine to generate a transition page, including:

[0063] Drawing driving information based on a lightweight graphics engine to generate first display data;

[0064] Generating second display data according to entertainment information in the display content of the instrument interface;

[0065] A transition page is generated according to the first display data and the second display data.

[0066] In this embodiment, the displayed information may include driving information such as speed, gear, battery power, and cruising range, as well as entertainment information such as music playback screen and navigation.

[0067] According to the vehicle motion signal and state signal fed back by the vehicle system, the driving information can be drawn based on the lightweight graphics engine to generate the first display data. That is, the first display data can indicate the display content of the driving information such as speed, gear, battery power, and cruising range that changes in response to the relevant signals.

[0068] The lightweight graphics engine may include engines such as LVGL, MicroGFX, Embedded Wizard, and EmWin, which may be selected according to actual needs and are not specifically limited here. For example, the lightweight graphics engine may be an LVGL engine.

[0069] The entertainment information in the display content of the instrument interface can also be directly copied to generate the second display data. In other words, the second display data can indicate the display content of the entertainment information, and the display content of this part is the same as the display content of the instrument interface and will not change according to the real-time situation of the vehicle.

[0070] A transition page may be generated based on the first display data and the second display data. It is understood that the transition page may include driving information updated in real time based on the real-time driving status of the vehicle and entertainment information that does not change. It is understood that although the driving information may be updated in real time, the same type of driving information is displayed in the same position as the instrument interface.

[0071] In this way, the user's perception of abnormal situations in the instrument program can be reduced, and the driving information of the transition page can be updated by the lightweight graphics engine while using fewer system resources, so that the user can obtain the accurate driving status of the vehicle in real time, further improving driving safety.

[0072] In some embodiments, obtaining the display status of the instrument interface on the instrument screen includes:

[0073] Monitoring the heartbeat signal of the instrument program, which is a signal sent by the instrument program according to a preset period;

[0074] When no heartbeat signal is detected within a first time period, it is determined that the instrument interface display is abnormal; wherein the first time period is determined according to a preset cycle.

[0075] In this embodiment, the keep-alive program can monitor the heartbeat signal of the instrument program. The heartbeat signal can be a signal sent by the instrument program according to a preset period, and the preset period can be a preset time period, for example, the preset period can be t1, and the instrument program sends a heartbeat signal every t1.

[0076] If the heartbeat signal is not detected within the first time period, it can be considered that the instrument program may be stuck, and the instrument interface display can be determined to be abnormal. The first time period can be determined according to a preset period, and the first time period can be greater than or equal to the preset period.

[0077] In this way, the display status of the instrument interface can be judged by monitoring the heartbeat signal of the instrument program, avoiding the situation where an abnormal display of the instrument interface is misjudged as a normal display due to the existence of the instrument program process. This improves the accuracy of the display status of the instrument interface, and enables timely processing of display abnormalities, further improving driving safety.

[0078] In some embodiments, when the heartbeat signal is not detected for a period exceeding a threshold, before determining that the instrument interface display is abnormal, the method further includes:

[0079] Get the actual startup time and standard startup time of the instrument program;

[0080] Determine the delay rate of the instrument procedure based on the actual startup time and the standard startup time;

[0081] A first time period is determined according to a preset period and a delay rate.

[0082] In this embodiment, the actual startup time and the standard startup time of the instrument program can be obtained. The standard startup time can be the time required for the instrument program to start from the beginning to the completion of startup when the network is normal.

[0083] The standard startup time can be a time predetermined based on basic information such as the model version of the instrument program, or it can be a time determined based on the historical startup times of multiple instrument programs. For example, the minimum value in the historical startup time can be determined as the standard startup time, and the average of multiple values ​​in the historical startup time whose standard deviation meets the requirements can also be determined as the standard startup time.

[0084] The actual startup time is the actual time taken for the instrument program to start from the beginning to the completion of the startup.

[0085] The delay rate of the instrument program may be determined according to the actual startup time and the standard startup time. For example, the delay rate may be a ratio of the actual startup time to the standard startup time.

[0086] The first time period may be determined according to a preset period and a delay rate. For example, the first time period may be the product of the preset period and the delay rate.

[0087] In this way, the situation in which the keep-alive program receives the heartbeat signal with a lag due to network delay can be considered, and a more accurate first time period can be calculated based on the preset cycle and delay rate, thereby improving the accuracy of abnormality judgment on the instrument interface display.

[0088] In order to facilitate understanding of the display control method of the instrument screen provided by the above embodiment, the display control method of the instrument screen is described below with a specific scenario embodiment. Figure 3 As shown, this scenario embodiment may include:

[0089] Step 301, the keep-alive program monitors the heartbeat signal of the instrument program;

[0090] Step 302, whether a heartbeat signal is detected within the first time period, if yes, execute step 303, if no, execute step 305;

[0091] Step 303, whether the transition page has been displayed, if yes, execute step 304, if not, execute step 301;

[0092] Step 304, hiding the transition page;

[0093] Step 305, whether the transition page has been displayed, if yes, execute step 301, if no, execute step 306;

[0094] Step 306, display the transition page and reset the instrument program.

[0095] Based on the display control method of the instrument screen provided in the above embodiment, the present application also provides an embodiment of a display control device of the instrument screen.
