[0058] Figure 1 This is a flow chart of a vehicle-mounted split-screen display method provided by an embodiment of the present invention. This embodiment is at least applicable to vehicle-mounted split-screen display and dynamic position switching scenarios of various types of manned vehicles, such as fuel vehicles, hybrid vehicles, plug-in hybrid vehicles, pure electric vehicles, etc. The vehicle-mounted split-screen display method can be, but is not limited to, executed by the vehicle-mounted split-screen display device in the embodiment of the present invention as the execution subject, and the execution subject can be implemented in software and / or hardware. Figure 1 As shown, the vehicle-mounted split-screen display method includes at least the following steps:

[0059] S1. In response to the vehicle computer being in a split-screen state, monitor the real-time gear switching of the vehicle.

[0060] S2. If the vehicle gear is switched to the forward gear, check whether the vehicle's assisted driving function is turned on.

[0061] Among them, the assisted driving function can correspond to the vehicle's advanced driver assistance system (ADAS), which can display the status of other vehicles, pedestrians, etc. around the vehicle on the car screen, and is mainly suitable for assisted driving scenarios.

[0062] S3. If the assisted driving function is turned on and the assisted driving application is displayed on the secondary split screen of the vehicle computer, the split screen switching process is triggered.

[0063] S4. In response to the triggering of the split-screen switching process, the main application parameters, sub-application parameters and split-screen line parameters after the split-screen switching are calculated according to the main split-screen application position parameters, sub-split-screen application position parameters and split-screen line position parameters of the vehicle computer.

[0064] Among them, the main split screen may refer to the split screen close to the driver's side; correspondingly, the secondary split screen may refer to the split screen away from the driver's side.

[0065] Android application display windows are organized in a tree structure. The car's head unit screen can be considered a single display, displaying different applications, each considered a task. When displayed full screen, tasks are arranged in a stack. When split (using two sub-screens as an example), one display simultaneously displays two tasks, with the task area occupying half the screen.

[0066] Figure 2 This is a schematic diagram of a screen split without performing split-screen switching provided by an embodiment of the present invention, see Figure 2 When split screen is activated, two applications are displayed on the screen, namely desktop and navigation. Figure 3 This is an application tree structure diagram provided by an embodiment of the present invention, such as Figure 3 As shown, the two Tasks represent two applications respectively. For example, a rectangular coordinate system is established with the lower left corner of the screen as the origin, the horizontal direction to the right from the origin as the positive direction of the x-axis, and the vertical direction upward from the origin as the positive direction of the y-axis. The range of the navigation application can be the area covered by (857.000, 0.000)-(2560.000, 1327.000) (the range of the aforementioned navigation application is the secondary split-screen application position parameter), the range of the desktop application can be the area covered by (0.000, 0.000)-(849.000, 1327.000) (the range of the aforementioned desktop application is the main split-screen application position parameter), and the range of the split-screen bar can be the area covered by (825.000, 0.000)-(881.000, 1327.000) (the range of the aforementioned split-screen bar is the split-screen line position parameter).

[0067] Adaptively, after performing split-screen switching, Figure 4 is a schematic diagram of a screen split after performing split-screen switching provided by an embodiment of the present invention, Figure 4It can be seen that after executing split-screen switching, the navigation application switches to the left side of the screen, the desktop application switches to the right side of the screen, and the position of the split-screen bar also changes. At this time, the range of the navigation application can be the area covered by (0.000, 0.000)-(1703.000, 1327.000) (at this time, the range of the navigation application is the main application parameter), the range of the desktop application can be the area covered by (1711.000, 0.000)-(2560.000, 1327.000) (at this time, the range of the desktop application is the secondary application parameter), and the range of the split-screen bar can be the area covered by (1679.000, 0.000)-(1735.000, 1327.000) (at this time, the range of the split-screen bar is the split-screen line parameter).

[0068] S5. Generate a split-screen switching animation based on the main application parameters, the sub-application parameters, the split-screen line parameters, and the real-time screenshots of the main and sub-applications, so as to complete the split-screen switching during the playback of the split-screen switching animation.

[0069] Among them, the real-time screenshots of the main and secondary applications can be composed of real-time screenshots of the main application and real-time screenshots of the secondary application; among them, the real-time screenshots of the main application can refer to the screenshots of the application displayed on one side of the main split screen at any time, and the real-time screenshots of the secondary application can refer to the screenshots of the application displayed on one side of the secondary split screen at any time.

[0070] Understandably, due to the real-time requirements of animation display, this step cannot take too long, otherwise it will cause delays in animation generation and playback, affecting system smoothness. After careful research, the inventors discovered that optimizing the Gaussian blur layer process can be used. Because the main factor affecting the generation time of the Gaussian blur layer is the resolution of the input screenshot, the smaller the resolution, the faster the generation time. Therefore, it is necessary to find an appropriate balance between the quality of the blurred layer and the image resolution.

[0071] In a specific embodiment, optionally, the aforementioned step S5 at least includes:

[0072] (5-1) Generate a main application cover layer and a sub-application cover layer based on the main application parameters, the sub-application parameters, and the split screen line parameters.

[0073] Among them, the main application covering layer can be a layer covering the main split-screen application, and the secondary application covering layer can be a layer covering the secondary split-screen application.

[0074] (5-2) Get real-time screenshots of the main application.

[0075] (5-3) The resolution of the real-time screenshot of the main application is proportionally reduced from the original resolution to the first preset resolution.

[0076] The first preset resolution may be 50% of the original resolution.

[0077] (5-4) Performing a first Gaussian blur algorithm on the real-time screenshot of the main application with a first preset resolution.

[0078] (5-5) Restore the resolution of the real-time screenshot of the main application processed by the first Gaussian blur algorithm to the original resolution to obtain a first screenshot.

[0079] (5-6) Get real-time screenshots of secondary applications.

[0080] (5-7) The resolution of the real-time screenshot of the secondary application is proportionally reduced from the initial resolution to a second preset resolution.

[0081] The second preset resolution may be 50% of the initial resolution.

[0082] (5-8) Perform a second Gaussian blur algorithm on the real-time screenshot of the secondary application with a second preset resolution.

[0083] (5-9) The resolution of the real-time screenshot of the secondary application processed by the second Gaussian blur algorithm is restored to the initial resolution to obtain a second screenshot.

[0084] (5-10) Construct a mapping relationship between the first screenshot and the main application cover layer, and a mapping relationship between the second screenshot and the secondary application cover layer.

[0085] (5-11) Generate a split-screen switching animation based on the first screenshot and the second screenshot constructed based on the completed mapping relationship (for example, the first screenshot and the second screenshot can be merged, and the merged screenshot can be delivered to the animation playback thread for processing) to complete the split-screen switching during the split-screen switching animation playback process.

[0086] According to the inventor's test, the average time to generate a screenshot is reduced by 70% with the configuration of this embodiment, which can basically meet the requirements of real-time fuzzy generation, and the delay is acceptable. Specific test results are shown in Table 1.

[0087] Table 1

[0088]

[0089] The technical solution provided by the embodiment of the present invention first monitors the real-time gear switching of the vehicle in response to the vehicle computer being in a split-screen state; further, if the vehicle gear is switched to a forward gear, it detects whether the vehicle's assisted driving function is turned on; further, if the assisted driving function is turned on and the assisted driving application is displayed on the secondary split-screen of the vehicle computer, the split-screen switching process is triggered; further, in response to the triggering of the split-screen switching process, the main application parameters, secondary application parameters and split-screen line parameters after the split-screen switching are calculated based on the main split-screen application position parameters, secondary split-screen application position parameters and split-screen line position parameters of the vehicle computer; finally, a split-screen switching animation is generated based on the main application parameters, secondary application parameters, split-screen line parameters and real-time screenshots of the main and secondary applications to complete the split-screen switching during the split-screen switching animation playback. In view of this, the embodiment of the present invention can realize the dynamic position switching of the vehicle computer split-screen application according to the user's actual vehicle usage scenario, which is conducive to improving the user's vehicle usage experience.

[0090] It should be noted that, in addition to the operating conditions where the vehicle gear is switched to the forward gear, the assisted driving function is turned on, and the assisted driving application is displayed on the secondary split screen of the vehicle computer, the embodiment of the present invention also provides the following vehicle operating conditions that can trigger the split-screen switching process based on the actual use of the user.

[0091] In another specific embodiment, optionally, after the aforementioned step S1, the method further includes:

[0092] If the vehicle gear is switched to reverse gear, the system detects whether the vehicle's reversing image application is displayed on the secondary split screen of the vehicle computer. If so, the split screen switching process is triggered.

[0093] Based on this, Figure 5 This is a flow chart of another vehicle split-screen display method provided by an embodiment of the present invention, see Figure 5 The vehicle-mounted split-screen display method includes at least the following steps:

[0094] S1. In response to the vehicle computer being in a split-screen state, monitor the real-time gear switching of the vehicle.

[0095] S6. If the vehicle gear is switched to reverse gear, it is detected whether the vehicle's reversing image application is displayed on the secondary split screen of the vehicle computer. If so, the split screen switching process is triggered.

[0096] S2. If the vehicle gear is switched to the forward gear, check whether the vehicle's assisted driving function is turned on.

[0097] S3. If the assisted driving function is turned on and the assisted driving application is displayed on the secondary split screen of the vehicle computer, the split screen switching process is triggered.

[0098] S4. In response to the triggering of the split-screen switching process, the main application parameters, sub-application parameters and split-screen line parameters after the split-screen switching are calculated according to the main split-screen application position parameters, sub-split-screen application position parameters and split-screen line position parameters of the vehicle computer.

[0099] S5. Generate a split-screen switching animation based on the main application parameters, the sub-application parameters, the split-screen line parameters, and the real-time screenshots of the main and sub-applications, so as to complete the split-screen switching during the playback of the split-screen switching animation.

[0100] Obviously, this embodiment can automatically perform a split-screen switching operation when the vehicle gear is switched to reverse gear and the reversing image application is displayed on the secondary split screen, so as to switch the reversing image application to the main split-screen area, which can simplify the driver's operation and improve driving safety.

[0101] In another specific embodiment, optionally, before the aforementioned step S4, the method further includes at least:

[0102] In response to the vehicle computer being in a split-screen state, identifying whether the user issues a screen switching instruction;

[0103] If so, the split-screen switching process is triggered according to the screen switching instruction.

[0104] Based on this, Figure 6 This is a flow chart of another vehicle-mounted split-screen display method provided by an embodiment of the present invention, see Figure 6 The vehicle-mounted split-screen display method includes at least the following steps:

[0105] S1. In response to the vehicle computer being in a split-screen state, monitor the real-time gear switching of the vehicle.

[0106] S2. If the vehicle gear is switched to the forward gear, check whether the vehicle's assisted driving function is turned on.

[0107] S3. If the assisted driving function is turned on and the assisted driving application is displayed on the secondary split screen of the vehicle computer, the split screen switching process is triggered.

[0108] S7. In response to the vehicle computer being in a split-screen state, identifying whether the user issues a screen switching instruction.

[0109] Among them, the screen switching instruction can be a voice instruction, a gesture instruction, etc.

[0110] S8. If yes, trigger the split-screen switching process according to the screen switching instruction.

[0111] S4. In response to the triggering of the split-screen switching process, the main application parameters, sub-application parameters and split-screen line parameters after the split-screen switching are calculated according to the main split-screen application position parameters, sub-split-screen application position parameters and split-screen line position parameters of the vehicle computer.

[0112] S5. Generate a split-screen switching animation based on the main application parameters, the sub-application parameters, the split-screen line parameters, and the real-time screenshots of the main and sub-applications, so as to complete the split-screen switching during the playback of the split-screen switching animation.

[0113] As you can see, on vehicles equipped with the zoned voice control feature, when a user is using at least one split-screen app simultaneously, the car computer can, but is not limited to, switch between split-screens based on the location of the user's voice command. For example, if the main split-screen area currently displays App A and the secondary split-screen area displays App B, and the driver issues a voice command to open App B, the car computer will execute the app switching function, swapping Apps A and B. This feature not only simplifies driver operation and improves driving safety, but also enhances the user experience of the voice control feature.

[0114] In another specific embodiment, optionally, before the aforementioned step S4, the method further includes at least:

[0115] In response to the vehicle computer being in a split-screen state, identifying an activation state of a handset-vehicle interconnection function in the vehicle;

[0116] If the car-to-car interconnection function is enabled and the car-to-car interconnection application list is displayed on the main split screen of the car computer, the split-screen switching process will be triggered when the user opens at least one mobile application.

[0117] Based on this, Figure 7 This is a flow chart of another vehicle-mounted split-screen display method provided by an embodiment of the present invention, see Figure 7 The vehicle-mounted split-screen display method includes at least the following steps:

[0118] S1. In response to the vehicle computer being in a split-screen state, monitor the real-time gear switching of the vehicle.

[0119] S2. If the vehicle gear is switched to the forward gear, check whether the vehicle's assisted driving function is turned on.

[0120] S3. If the assisted driving function is turned on and the assisted driving application is displayed on the secondary split screen of the vehicle computer, the split screen switching process is triggered.

[0121] S9. In response to the vehicle computer being in a split-screen state, identifying an activation state of a hand-vehicle interconnection function in the vehicle.

[0122] S10. If the car-vehicle interconnection function is enabled and the car-vehicle interconnection application list is displayed on the main split screen of the car computer, the split screen switching process is triggered when the user opens at least one mobile phone application.

[0123] S4. In response to the triggering of the split-screen switching process, the main application parameters, sub-application parameters and split-screen line parameters after the split-screen switching are calculated according to the main split-screen application position parameters, sub-split-screen application position parameters and split-screen line position parameters of the vehicle computer.

[0124] S5. Generate a split-screen switching animation based on the main application parameters, the sub-application parameters, the split-screen line parameters, and the real-time screenshots of the main and sub-applications, so as to complete the split-screen switching during the playback of the split-screen switching animation.

[0125] As you can see, after the user's phone is connected to the car computer and the car-connected app is open, the car computer can activate the car-connected app list function and display it in the main split-screen area. When the user clicks on a specific mobile phone app, the car computer can execute the application switch and switch the car-connected app to the secondary split-screen area. It is understandable that the reason for this setting is that the secondary split-screen display area is larger than the main split-screen area. Switching the car-connected app to the secondary split-screen area can achieve a better display effect, which is conducive to improving the user's car experience.

[0126] Figure 8 This is a structural diagram of a split-screen display device for a vehicle provided by an embodiment of the present invention. This embodiment is at least applicable to split-screen display and dynamic position switching scenarios of various types of manned vehicles, such as fuel vehicles, hybrid vehicles, plug-in hybrid vehicles, pure electric vehicles, etc. The split-screen display device for the vehicle can be implemented in software and / or hardware.
