Similarly, for clarity and brevity, the following description omits the description of well-known functions and configurations.

According to an embodiment of the present application, FIG. 1 is a schematic flowchart of a first screen switching display method according to an embodiment of the present application, in which the present embodiment is described during execution of an application program in a smart rear-view mirror. It is applied when the content provided by the application program is displayed by switching between the screen of the smart rear-view mirror and the screen of another in-vehicle terminal. Other in-vehicle terminals are other terminals of the smart rear-view mirror among all in-vehicle terminals in a smart car, and include, but are not limited to, in-vehicle infotainment, fingerprint readers, identity recognition devices, driving behavior analyzers, and the like. Other in-vehicle terminals are required to have a screen arranged and to be able to communicate with a smart rear-view mirror.

The method may be performed by a screen switching display device, which device may be implemented in the form of software and / or hardware, or integrated in a smart rearview mirror.

As shown in FIG. 1, the screen switching display method according to this embodiment may include the following steps.

S110: The display data on the current screen of the target application program is stored during the execution of the target application program.

The target application program may be any application program installed in the smart rearview mirror, for example, an application program such as a voice assistant, audio video or game. The current screen may be the screen of a smart rear-view mirror or the screen of another vehicle-mounted terminal, for example, the screen of vehicle-mounted infotainment. Taking in-vehicle infotainment as an example, after the smart rear-view mirror establishes a connection relationship with in-vehicle infotainment, the display data of the target application program switches from the smart rear-view mirror screen to the in-vehicle infotainment screen. Is the in-vehicle infotainment screen, and after the smart rear-view mirror screen closes or displays a screen saver and the smart rear-view mirror cuts off the connection with the in-vehicle infotainment, the display data of the target application program is in-vehicle. The infotainment screen is switched to the smart rear-view mirror screen, and at this time, the current screen is the smart rear-view mirror screen, and the in-vehicle infotainment screen is closed or the screen saver is displayed.

When the target application program is executed, the smart rear-view mirror stores the display data of the target application program on the current screen in real time. For example, after the user logs in to the game application program, the display data includes guinea information, images, and the like in the game interface displayed on the current screen. To be selectable, the smart rearview mirror may store all display data on the current screen of the target application program running, or only the latest display data on the current screen of the target application program. The historical data may be covered.

S120: In response to monitoring the screen switching signal, the switched display state including the mirroring display state and the local display state is determined.

The user can switch the screen by blocking or establishing a connection relationship between the smart rear-view mirror and another in-vehicle terminal. Selectably, the in-vehicle infotainment can be connected to the smart rear-view mirror via USB (Universal Serial Bus) to realize data exchange. Based on this, the user can switch screens by plugging and unplugging the USB interface.

Taking in-vehicle infotainment as an example, when an application program for data transmission is installed in both the smart back mirror and the in-vehicle infotainment, and the smart back mirror is connected to the in-vehicle infotainment via USB, data Trigger the start of the application program for transmission and prepare the data transmission. After the application program for data transmission in the smart rear-view mirror is started, the screen switching signal from the smart rear-view mirror to the in-vehicle infotainment is transmitted. Correspondingly, when the USB connection between the smart rear-view mirror and the in-vehicle infotainment is cut off, it triggers to terminate the data transmission application program. Before the application program for data transmission in the smart rear-view mirror is terminated, the screen switching signal from the in-vehicle infotainment to the smart rear-view mirror is transmitted.

To be selectable, the smart rearview mirror determines the switched display state and the switched screen after receiving the screen switching signal, i.e., in response to monitoring the screen switching signal. The display state in this embodiment is the display state of the smart rear-view mirror, and when the screen switching from the smart rear-view mirror to the in-vehicle infotainment is received, that is, the screen switching notification from the smart rear-view mirror to the in-vehicle infotainment is received. When the message is received, the smart rear-view mirror switches to the mirroring display state, and the switched screen is the in-vehicle infotainment, and when the screen switching from the in-vehicle infotainment to the smart rear-view mirror is monitored, that is, from the in-vehicle infotainment to the smart When the screen switching notification to the rear-view mirror is received, the smart rear-view mirror is switched to the local display state, and the switched screen is the smart rear-view mirror.

Note that this embodiment is applied when monitoring screen switching during execution of the target application program, and in order to avoid interruption of the application program, a target display style that matches the switched display state is determined. However, it is necessary to display the display data on the switched screen based on the target display style. On the other hand, when the target application program is not running, for example, when the desktop is displayed or waiting, and the screen switching is monitored, there is no valid display data, so there is no need to perform subsequent steps. ..

S130: A target display style that matches the switched display state is determined.

Based on the above description, the switched display state indicates which screen to display after switching, so that different screens have different resolutions and do not affect normal viewing. The display style that adapts to the resolution should be determined. Of course, even if two screens that can be switched to each other have the same resolution, the display style can be determined based on parameters such as screen mounting position and display performance.

In this embodiment, the display state has a correspondence relationship with the display style. If the switched display state is the local display state and the switched screen is the smart rearview mirror screen, the target display style that matches the local display state should be the style that matches the smart rearview mirror screen. .. When the switched display state is the mirroring display state and the switched screen is the screen of another in-vehicle terminal, the target display style that matches the mirrored display state should be the style that matches the screen of the other in-vehicle terminal. is. For convenience of description and distinction, a display style that matches the switched display state is called a target display style. To be selectable, the target display style includes the format of the display data (eg, characters or images), the page layout and the trigger position and trigger effect on the display data.

S140: Display data is displayed on the switched screen based on the target display style.

If the current screen is the in-vehicle infotainment screen and the switched screen is the smart rearview mirror screen, the smart rearview mirror renders and displays the stored display data on the local screen in a target display style. .. When the current screen is the screen of the smart rear-view mirror and the switched screen is the screen of the vehicle-mounted infotainment, the display data is displayed on the screen of the vehicle-mounted infotainment based on the target display style.

In the embodiment of the present application, by storing the display data on the current screen of the target application program during execution of the target application program, a data source is provided on the switched screen, and the display data of the target application program is displayed. By displaying the display data based on the target display style that matches the switched display state while ensuring that it is not interrupted, the target display style adapts to the switched screen and the display data is changed to the switched screen. Ensure display and ensure clear, complete and beautiful display. Therefore, this embodiment solves the technical problem that the display data of the application program is interrupted and lost after the screen is switched, and ensures the consistency of the data display of the application program after the screen is switched. Improve the user experience, as well as the clarity, completeness and beauty of the display.

According to the embodiment of the present application, FIG. 2 is a schematic flowchart of the second screen switching display method according to the embodiment of the present application, and this embodiment is an optimized version of the above embodiment.

To be selectable, the operation of "determining the target display style that matches the switched display state" is changed to "if the switched display state does not match the current display style of the display data, the switch is made. It is subdivided into "Create a target display style that matches the display state" and provides a method for determining the target display style.

To be selectable, the operation of "displaying the display data on the switched screen based on the target display style" is performed by "in the smart back mirror, the display data is rendered based on the target display style. , Generate video data and transmit the video data to the in-vehicle infotainment so that the in-vehicle infotainment displays the video data on the in-vehicle infotainment screen ”, based on the display style. It is applied to in-vehicle infotainment that does not have a function to display data.

As shown in FIG. 2, the screen switching display method according to this embodiment may include the following steps.

S210: The display data on the current screen of the target application program is stored during the execution of the target application program.

S220: In response to monitoring the screen switching signal, the switched display state including the mirroring display state and the local display state is determined.

S230: Determines whether or not the switched display state matches the current display style of the display data, and if matching is performed, that is, when the switched display state matches the current display style of the display data, the process proceeds to S231. However, if there is no match, that is, if the switched display state does not match the current display style of the display data, the process proceeds to S232.

S231: The display data is displayed on the switched screen based on the current display style. This operation ends.

S232: Create a target display style that matches the switched display state. Further, S233 is executed.

In one embodiment, the target display style is created based on the switched screen resolution. In addition, after creating the target display style, the current display style and the display interface on the current screen are destroyed, freeing up storage space. After the display interface on the current screen is destroyed, the default interface is used instead. For example, if the default interface is the default menu interface, the smart rearview mirror screen display state switches from the local display state to the mirrored display state, and the mirrored display state does not match the current display style, then the current display interface is used. By discarding and displaying the default menu interface, after the screen of the smart rearview mirror is switched, the display data will not be displayed further, the display data leakage will be avoided, the user's privacy will be protected, and the user will be able to use it. When using the switched screen, prevent others from manipulating the data displayed on the current screen and increase security.

In one application scene, assuming that the local display state matches the display style A, the mirrored display state matches the display style B. In some cases, since the switched display state is the mirrored display state and the current display style is the display style A, matching is not possible, and a display style B that matches the mirrored display state is created, and the display style A and the display style A and the display style A are created. Destroy the smart rearview mirror display interface and display the default menu interface. In other cases, the switched display state is the mirrored display state, the current display style is the display style B, the switched display state matches the current display style, and the display style B is the target display style. Destroy the smart rearview mirror display interface and display the default menu interface. In the other case, since the switched display state is the local display state and the current display style is the display style B, matching is not possible, and a display style A that matches the local display state is created to create a display style. Destroy the display interface of B and in-vehicle infotainment and display the default menu interface. In other cases, the switched display state is the local display state, the current display style is the display style A, the switched display state matches the current display style, and the display style A is the target display style. Discard the in-vehicle infotainment display interface and display the default menu interface.

S233: The display data is displayed on the switched screen based on the target display style.

In one application scene, the other in-vehicle terminal is the in-vehicle infotainment, the current screen is the screen of the smart rear-view mirror, and the switched screen is the in-vehicle infotainment screen. Based on this, the smart rear-view mirror renders the display data based on the target display style to generate video data, and the vehicle-mounted infotainment displays the video data on the vehicle-mounted infotainment screen. As described above, the video data is transmitted to the in-vehicle infotainment.

Specifically, the smart rearview mirror renders the display data on its auxiliary screen based on the target display style to generate video data, and the auxiliary screen of the smart rearview mirror is invisible to the user, and the video. In order to project the data to a plurality of types of in-vehicle terminals, it is necessary to make the resolution of the auxiliary screen higher than the resolution of all the in-vehicle terminals. Each of the video data includes at least one video frame corresponding to the displayed page of the displayed data on the current screen. For example, if the current interface has only one display page, the display data renders the display data based on the target display style to generate one video frame. Subsequently, the video data is encoded and then transmitted to the in-vehicle infotainment. In-vehicle infotainment is a style in which after receiving the encoded video data, it is decoded to obtain the video data, and the obtained video data is matched with the in-vehicle infotainment screen, and the in-vehicle infotainment is displayed. Video data can be displayed directly on the in-vehicle infotainment screen without adjusting the style.

In this embodiment, the smart rear-view mirror renders the display data to generate video data, so that the in-vehicle infotainment can be displayed directly, the operation process of the in-vehicle infotainment is reduced, and the screen switching display is performed. It is applied to in-vehicle infotainment that does not have the function of displaying data based on the display style.

In this embodiment, when the screen is switched during the execution of the target application program and the switched display state does not match the current interface style of the display data, the older display style is not used and the switched display state is matched. By creating and creating a target display style, the display style and display state can be matched, and the display data can be displayed clearly and completely on the switched screen, improving the user experience.

According to the embodiment of the present application, FIG. 3 is a schematic flowchart of a third screen switching display method according to the embodiment of the present application, and the present embodiment is a further optimization of the above embodiment. The dynamic proxy can be used to determine the display state, determine the target display style, and execute the display operation.

As shown in FIG. 3, the screen switching display method according to this embodiment may include the following steps.

S310: The display data on the current screen of the target application program is stored during the execution of the target application program.

S320: In response to monitoring the screen switching signal, the switched display state including the mirroring display state and the local display state is determined by the dynamic proxy.

S330: The dynamic proxy determines a target display style that matches the switched display state.

S340: The display data is displayed by the dynamic proxy on the switched screen based on the target display style.

In this embodiment, a dynamic proxy is dynamically created by using a reflection mechanism when responding to monitoring the screen switching signal. The dynamic proxy is used to proxy the current display object in the smart rearview mirror. The display object is used to display display data on a corresponding screen according to a default display style (smart rearview mirror display style or other in-vehicle terminal display style). After the screen is switched, continue to display the data in the old display style, or use the old display style and go back to display the default interface. In this embodiment, when the screen switching is monitored during the execution of the target application program, the operations of S320 to S340 are executed by the dynamic proxy instead of the display object. Correspondingly, the operations represented by the dynamic proxy are the operations of S320 to S340.

In this embodiment, a dynamic proxy is created only for the target application program that may interrupt the display, the above operation is executed by the dynamic proxy, and the current display object is not affected. There is no need to create a dynamic proxy for other non-disruptive application programs installed in the smart rearview mirror, and they can continue to display normally through the current display object. For example, a map image of a city with display data of a map application program, and after the screen is switched, the screen is switched so as to adapt to the switched screen without adjusting the style of the map image. Automatically scales the map of the city at equal proportions. Therefore, in this embodiment, the above-mentioned operation is executed by a dynamic proxy instead of the display object, and the code is easily realized without revising the operation position of the display object. In addition, it does not affect the normal display of other application programs.

According to the embodiment of the present application, FIG. 4a is a schematic flowchart of the fourth screen switching display method according to the embodiment of the present application, and this embodiment is a further optimization of the above embodiment.

To be selectable, the operation of "determining the target display style that matches the switched display state" is performed by "determining a display style candidate that matches the switched display state from the pre-stored display style, and the above. When there are two or more display style candidates, the resolution of the switched screen is acquired, and the target display style that matches the resolution of the switched screen is screened from the display style candidates. Therefore, the efficiency of determining the target display style is improved, and the display efficiency is further improved.

To be selectable, the operation of "remembering the display data on the current screen of the target application program while the target application program is being executed" is changed to "during the execution of the voice application program, on the current screen of the voice application program." The operation of "determining the target display style that matches the switched display state" is subdivided into "memorize the dialogue text of", and the operation "the text format that matches the switched display state and the text" The target application program is limited to the voice application program, and the display style of the dialogue text is subdivided.

As shown in FIG. 4a, the screen switching display method according to the present embodiment may include the following steps.

S410: During the execution of the voice application program, the dialogue text on the current screen of the voice application program is stored.

During execution of the voice application program, the user makes a voice to the voice application program, the voice application program recognizes the user's voice, and then the response content is generated. Since the text corresponding to the user's voice and / or the response content is called the dialogue text and is displayed on the current screen, it can be understood that the dialogue text is the display data on the current screen.

Selectably, during the execution of the voice application program, the most recently generated set of dialogue text between the user and the voice application program is stored in real time. Specifically, one node is used to store a set of dialogue text, and a new node is used instead of the old node, thereby leaving the newest node, that is, storing the newest set of dialogue text. Ensure that you do.

FIG. 4b is a schematic screen display of a smart rear-view mirror according to an embodiment of the present application. The dialogue interface of the voice application program containing a set of dialogue texts is displayed on the screen. Specifically, the user makes a voice "Please display Zhang San's phone number" to the voice application program, displays the voice in text format on the current screen, and displays Zhang San's phone number. do. In addition, the text corresponding to the voice uttered by the user and the text "Zhangsan's telephone number" corresponding to the response content are stored in the node. After this, when the user makes another voice saying "Please display Li 4's phone number", in addition to the data displayed before this, the subsequent dialogue text "Display Li 4's phone number" is displayed. Please, "and Lee Shi's phone number can be displayed. However, when memorizing, it is necessary to cover the historical dialogue text with the subsequent dialogue text, that is, "Please display Li 4's phone number" and remember only Li 4's phone number, with less display data. The amount of storage is used, thereby reducing the amount of data displayed on which the screen has been switched and improving the efficiency of switching screens.

S420: In response to monitoring the screen switching signal, the switched display state including the mirroring display state and the local display state is determined.

S430: The text format matching the switched display state, the trigger position of the text, and the trigger effect are determined.

The display data is interactive text, the display style of which includes the text format and the trigger position and trigger effect of the text. The text format may be the font of the text, word spacing, line spacing, etc., the trigger position of the text may be the trigger position of actions such as selection, jump and revision to the text, and the trigger effect is: Visual effects such as selection, jumping, and revision of text, such as highlighting, font enlargement, and focus state.

Selectably, the smart rearview mirror can pre-store at least one display style (ie, the text format and the trigger position of the text) that matches the switched display state. Each display style corresponds to a different resolution. After determining the switched display state, it is possible to determine a display style candidate that matches the switched display state from the display styles stored in advance. When there are two or more display style candidates, the resolution of the switched screen is acquired, and from the display style candidates, a display style adapted to the resolution of the switched screen is screened as a target display style. Can be done. When there is only one display style candidate, the display style candidate is directly set as the target display style.

Illustratively, the smart rearview mirror stores in advance display style 1, display style 2 and display style 3 corresponding to the resolutions A × B, 2A × B and A × 2B, respectively, and the display style is a text format and text. Includes the trigger position of. The display style matches the local display state, and the display style 2 and the display style 3 match the mirrored display state. The resolution of the smart rear-view mirror is AxB, the resolution of the vehicle-mounted infotainment 1 is 2AxB, and the resolution of the vehicle-mounted infotainment 2 is Ax2B. When the switched display state is the mirroring display state, it is determined that the display style candidates include the display style 2 and the display style 3, and when the switched screen is the screen of the in-vehicle infotainment 1, the display style 2 is the target display style, and when the switched screen is the screen of the in-vehicle infotainment 2, the display style 3 is the target display style.

S440: Display the dialogue text on the switched screen based on the text format and the trigger position and trigger effect of the text.

In FIG. 4b, the screen resolution of the smart rearview mirror is AxB, and the current display style of the dialogue text is font size 4, word spacing 0.3 points, single line spacing, text selection, jumping and revision. Includes trigger positions for actions such as, as well as trigger effects that match font size, word spacing, and line spacing. FIG. 4b shows a highlight trigger effect when performing a selection operation on a telephone number.

FIG. 4c is a schematic screen display of the in-vehicle infotainment according to the embodiment of the present application. The screen resolution of the smart rearview mirror is 2A x B, the target display style of the dialogue text includes a font size of 15pt, a word spacing of 0.4 points, and a line spacing of 1.5 lines, and the trigger position is the dialogue text display position. The trigger effect should match the font size, word spacing, and line spacing of the target display style. FIG. 4c is a highlight trigger effect when performing a selection operation on the text, and the highlight range is wider and longer than that of FIG. 4b.

In this embodiment, the display style is stored in advance, and the target display style that matches the switched display state and adapts to the switched screen is screened from the stored display style in advance, thereby creating or discarding the display style. It is not necessary to improve the efficiency of determining the target display style, further improve the display efficiency, and improve the display fluency in the screen switching process.

This embodiment is applied when switching screens during execution of a voice application program. By storing the dialogue text on the current screen, a data source is provided on the switched screens and the target application program is displayed.
