Description

Technical Field

[0001] This invention belongs to the field of navigation projection technology, specifically relating to a navigation three-screen interactive control method, system, vehicle, and storage medium. Background Technology

[0002] With the development of automotive intelligence, connectivity, and hardware, cars are no longer just a means of transportation; they have become mobile intelligent cockpits, leading to a growing demand for rich in-car software applications. In-car maps are becoming the preferred navigation solution for an increasing number of users. Currently, the number of displays in automotive intelligent cockpits is increasing, and applications for vehicle control, comfort adjustments, system settings, and audio-visual entertainment are becoming more abundant. Enhancing driver safety while ensuring convenient and quick access to various information during driving has become a crucial requirement.

[0003] For example, patent document CN202210402955.4 discloses a smart cockpit multi-screen interaction system, method, and readable storage medium, belonging to the field of vehicle driving. This method allows users to share the corresponding vehicle screen content to a target vehicle screen in the direction of the swipe by swiping with three fingers. Alternatively, it allows passengers to long-press on the vehicle screen, obtaining the touch duration and the screen content within that duration. When the touch duration exceeds a preset duration, the screen content is shared to the target vehicle screen. This technology focuses on user-initiated screen projection methods, but does not consider the safety and convenience issues of user-initiated operation in a driving scenario, thus its practicality is limited.

[0004] For example, patent document CN202010005789.5 discloses a multi-screen interaction method based on a smart cockpit. This method proposes to establish a connection between the Linux and Android systems by establishing a server-side Socket communication in the Linux system and a client-side Socket communication in the Android system. Data is then exchanged between the two systems, thereby achieving information sharing and interaction between multiple screens. This technology focuses on the software solution for multi-screen interaction between different operating systems, without considering the actual screen projection logic and user experience of the smart cockpit software product.

[0005] Therefore, there is a need to develop a new navigation three-screen interactive control method, system, vehicle, and storage medium. Summary of the Invention

[0006] The purpose of this invention is to provide a navigation three-screen interactive control method, system, vehicle, and storage medium that can realize automatic switching of navigation information between the vehicle screen, instrument screen, and third screen.

[0009] If the automatic multi-screen navigation function is detected to be enabled and navigation has been initiated, the automatic screen casting function will be activated; otherwise, the automatic screen casting function will not be activated.

[0010] If the automatic screen mirroring function is detected to be activated, the screen mirroring trigger condition is a long-term application trigger, and the instrument panel can perform navigation screen mirroring, then full-screen navigation will be displayed on the instrument panel.

[0011] In response to the detection that the automatic screen casting function has been activated, the screen casting trigger condition is long-term application trigger, and the instrument panel cannot perform navigation screen casting, but the third screen can perform navigation screen casting, then the full-screen navigation is displayed through the third screen;

[0012] In response to the detection that the automatic screen mirroring function has been activated, the screen mirroring is triggered by a short application or by the vehicle screen switching from desktop one to desktop two, and the third screen can perform navigation screen mirroring, then full-screen navigation is displayed through the third screen;

[0013] In response to the detection that the automatic screen casting function has been activated, the screen casting trigger condition is a short-term application trigger or the vehicle screen switches from desktop one to desktop two, and the third screen cannot perform navigation screen casting, but the instrument panel screen can perform navigation screen casting, then the full-screen navigation is displayed through the instrument panel screen;

[0015] Optionally, it also includes:

[0016] When full-screen navigation is displayed on the instrument panel, if the IACC / ACC function is detected to be enabled and the third screen can perform navigation projection, then full-screen navigation will be displayed on the third screen.

[0017] Optionally, it also includes:

[0018] If the automatic screen mirroring function is detected to be activated, and the screen mirroring trigger condition is long-term application trigger, and the instrument panel screen cannot perform navigation screen mirroring, then neither the instrument panel screen nor the third screen will perform navigation screen mirroring.

[0019] Optionally, it also includes:

[0020] If the automatic screen mirroring function is detected to be activated, and the screen mirroring is triggered by a short-term application or by the vehicle's infotainment screen switching from desktop one to desktop two, and the third screen cannot perform navigation screen mirroring, then neither the instrument panel nor the third screen will perform navigation screen mirroring.

[0021] Optionally, it also includes:

[0022] When the automatic multi-screen navigation function is enabled and navigation has been initiated, in response to the user's active action of projecting navigation onto the instrument panel screen, full-screen navigation will be displayed on the instrument panel screen.

[0023] Optionally, it also includes:

[0024] When the automatic multi-screen navigation function is enabled and navigation has been initiated, in response to the user's active action of casting navigation to the third screen, full-screen navigation will be displayed on the third screen.

[0025] Optionally, it also includes:

[0026] When full-screen navigation is displayed on the instrument panel, in response to the detection that the vehicle screen has switched back to the desktop, the instrument panel is notified to exit full-screen navigation and return to the page before full-screen navigation was entered.

[0027] Optionally, it also includes:

[0028] When full-screen navigation is displayed on the third screen, in response to the detection that the vehicle screen has switched back to the desktop, the third screen is notified to exit full-screen navigation and return to the page before entering full-screen navigation.

[0029] Optionally, when the instrument panel is in the IACC / ACC display interface, it is considered that the instrument panel cannot perform navigation projection;

[0030] When the instrument panel is not in the IACC / ACC display interface, it is assumed that the instrument panel can perform navigation projection.

[0031] Optionally, if the third screen is displaying lyrics or the rearview camera screen, it is assumed that the third screen cannot perform navigation projection.

[0032] When the third screen is not on the lyrics or cloud-based rearview camera page, it is assumed that the third screen can perform navigation projection.

[0036] The present invention has the following advantages:

[0037] (1) The entire navigation three-screen interactive control system divides the applications on the vehicle into two categories: long-term applications and short-term applications. It makes full use of the display functions of the instrument panel and the third screen. When the vehicle is in navigation mode and music or other applications are turned on, the system can automatically project the navigation onto the instrument panel or the third screen according to preset rules. This not only makes it convenient for the driver to view the navigation guidance while driving, but also allows for convenient operation of other applications on the vehicle. It also facilitates the use of other applications (such as entertainment applications) by other passengers in the vehicle, thus taking into account the driving and riding needs of both the driver and passengers to obtain different information in the vehicle. At the same time, it avoids the insecurity and inconvenience caused by the existing active operation.

[0038] (2) Based on the priority of the vehicle application scenarios, provide appropriate screen projection logic and conflict logic solutions between the instrument panel and other content on the third screen and the full-screen navigation display, so as to ensure that other information on the instrument panel and the third screen is not interfered with.

[0045] The present invention will now be described in detail with reference to the accompanying drawings.

[0046] In this embodiment, a navigation three-screen interactive control method includes the following steps:

[0047] Obtain information about whether the automatic multi-screen navigation function is enabled, as well as the navigation initiation signal;

[0048] If the automatic multi-screen navigation function is detected to be enabled and navigation has been initiated, the automatic screen casting function will be activated; otherwise, the automatic screen casting function will not be activated.

[0049] In response to the detection that the automatic screen casting function has been activated, the screen casting trigger condition is long-term application trigger, and the instrument panel 2 can perform navigation screen casting, then full-screen navigation is displayed through the instrument panel 2;

[0050] In response to the detection that the automatic screen casting function has been activated, the screen casting trigger condition is long-term application trigger, and the instrument panel 2 cannot perform navigation screen casting, but the third screen 3 can perform navigation screen casting, then full-screen navigation is displayed through the third screen 3;

[0051] In response to the detection that the automatic screen casting function has been activated, the screen casting trigger condition is short-term application trigger or the vehicle screen 4 switches from desktop one to desktop two, and the third screen 3 can perform navigation screen casting, then full-screen navigation is displayed through the third screen 3;

[0052] In response to the detection that the automatic screen casting function has been activated, the screen casting trigger condition is short-term application trigger or the vehicle screen 4 switches from desktop one to desktop two, and the third screen 3 cannot perform navigation screen casting, but the instrument panel screen 2 can perform navigation screen casting, then full-screen navigation is displayed through the instrument panel screen 2.

[0053] This method can automatically switch navigation information between the in-vehicle infotainment system, instrument panel, and third screen based on the current status of the in-vehicle infotainment system and follow the principle that only one screen should be supported for full-screen navigation at a time. This provides users with convenient map navigation information without being disturbed by other applications, while also allowing other occupants in the vehicle to use other in-vehicle infotainment system functions.

[0054] In this embodiment, desktop 1 is the navigation page, desktop 2 is the vehicle system 1 APP entry interface, and the foreground is the interface where the currently running software is located.

[0055] In this embodiment, long-term application triggering refers to opening an audio-visual APP, such as the playback page of local videos in the car system 1, which is displayed on the front end of the system, regardless of whether the APP is paused or playing.

[0056] In this embodiment, short-term application triggering refers to the vehicle screen 4 being on other pages that are not desktop one or two, such as non-video playback pages such as image, air conditioning, lighting, EaglePilot, Bluetooth phone, Xiaoou voice, etc.

[0057] In this embodiment, the third screen 3 is installed on the dashboard near the windshield. The size of the third screen 3 is generally smaller than that of the vehicle infotainment screen 4 and the instrument panel screen 2.

[0058] In this embodiment, when the triggering condition is short-term application triggering or the vehicle screen 4 switches from desktop one to desktop two, since only short-term screen projection is required, although the size of the third screen 3 is small, it has no impact on short-term screen projection. In addition, since the instrument panel 2 itself displays a lot of content, frequent switching will affect the visual effect. Therefore, when there is a need for short-term screen projection, the system will give priority to the third screen 3.

[0059] In this embodiment, when the trigger condition is a long-term application trigger, that is, a long-term screen projection is required, the system will give priority to the instrument panel 2 when there is a need for long-term screen projection because the instrument panel 2 is large in size and easy for the driver to see.

[0060] In this embodiment, when the instrument panel 2 is in the IACC / ACC display interface, it is considered that the instrument panel 2 cannot perform navigation projection; when the instrument panel 2 is in a non-IACC / ACC display interface, it is considered that the instrument panel 2 can perform navigation projection.

[0061] In this embodiment, when the third screen 3 is on the lyrics or cloud-eye rearview camera page, it is considered that the third screen 3 cannot perform navigation projection; when the third screen 3 is on a page other than lyrics or cloud-eye rearview camera page, it is considered that the third screen 3 can perform navigation projection.

[0062] This embodiment includes an automatic multi-screen navigation function switch. The factory default setting for this function is "on," but users can disable the entire multi-screen interaction system according to their needs. When the automatic multi-screen navigation function switch is detected as being on, the automatic multi-screen navigation function is considered to be enabled.

[0063] In this embodiment, a navigation three-screen interactive control method further includes: in response to the detection that the automatic screen projection function has been activated, the screen projection trigger condition is long-term application trigger, the instrument screen 2 cannot perform navigation screen projection, and the third screen 3 cannot perform navigation screen projection, then neither the instrument screen 2 nor the third screen 3 will perform navigation screen projection.

[0064] In this embodiment, a navigation three-screen interactive control method further includes: in response to detecting that the automatic screen projection function has been activated, and the screen projection trigger condition is short-term application trigger or the vehicle screen 4 switches from desktop one to desktop two, the third screen 3 cannot perform navigation screen projection, and the instrument screen 2 cannot perform navigation screen projection, then neither the instrument screen 2 nor the third screen 3 performs navigation screen projection.

[0065] In this embodiment, a navigation three-screen interactive control method further includes: when full-screen navigation is displayed on the instrument panel 2, in response to detecting that the IACC / ACC function is enabled and the third screen 3 can perform navigation projection, then full-screen navigation is displayed on the third screen 3; specifically:

[0066] When instrument panel 2 is already in full-screen navigation mode, and the user activates IACC / ACC, instrument panel control module 5 first determines whether navigation can be cast to the third screen 3. If it can, the third screen 3 displays full-screen navigation, and the instrument panel switches to the IACC / ACC interface. If the third screen 3 cannot be cast, instrument panel 2 is also forced to switch to the IACC / ACC interface. At this time, neither instrument panel 2 nor the third screen 3 displays full-screen navigation.

[0067] The following combination Figure 1 The flow of the navigation three-screen interactive control method described in this embodiment is explained in detail:

[0068] like Figure 2 As shown in this embodiment, a navigation three-screen interactive control method includes the following specific steps:

[0069] Step 1: Determine whether the automatic multi-screen interaction switch for navigation is turned on and whether navigation has been initiated. If yes, proceed to Step 2; otherwise, the process ends.

[0070] Step 2: Determine whether the screen mirroring is triggered by a long-term application, a short-term application, or by switching from desktop one to desktop two. If the trigger condition is a long-term application, proceed to step 3. If the trigger condition is a short-term application or a switch from desktop one to desktop two, proceed to step 6.

[0071] Step 3: Determine if the instrument panel 2 is in the IACC / ACC interface. If not, proceed to step 4; if yes, proceed to step 6.

[0072] Step 4: The instrument panel 2 displays full-screen navigation;

[0073] Step 5: Determine whether the IACC / ACC function is enabled. If not, proceed to step 4; if yes, proceed to step 6.

[0074] Step 6: Determine if the third screen 3 is on the lyrics or cloud-eye rearview camera page. If not, display full-screen navigation on the third screen 3. If so, proceed to step 7.

[0075] Step 7: Determine if instrument panel 2 is in the IACC / ACC interface. If not, proceed to step 4. If yes, neither instrument panel 2 nor the third screen 3 will display full-screen navigation.

[0076] like Figure 3As shown in this embodiment, a navigation three-screen interactive control method further includes: when the automatic multi-screen navigation function is enabled and navigation has been initiated, in response to detecting that the user actively projects the navigation onto the instrument panel screen, then displaying full-screen navigation on the instrument panel screen 2; the specific process is as follows:

[0077] Step 10: Determine whether the automatic multi-screen interaction switch for navigation is turned on and whether navigation is initiated. If yes, proceed to step 20; otherwise, the process ends.

[0078] Step 20: When the user actively projects the navigation onto the instrument panel 2 (e.g., by pointing three fingers at the top of the instrument panel 2 or by using voice control to "turn on full-screen navigation on the instrument panel"), the instrument panel 2 will switch to full-screen navigation regardless of whether it is in the IACC / ACC interface.

[0079] In this embodiment, manual switching has the highest priority.

[0080] like Figure 4 As shown in this embodiment, a navigation three-screen interactive control method further includes: when the automatic multi-screen navigation function is enabled and navigation has been initiated, in response to detecting that the user actively projects the navigation onto the third screen, then displaying full-screen navigation on the third screen 3; the specific process is as follows:

[0081] Step 100: Determine whether the automatic multi-screen interaction switch for navigation is turned on and whether navigation is initiated. If yes, proceed to step 200; otherwise, the process ends.

[0082] Step 200: When the user actively projects the navigation onto the third screen 3 (e.g., by using three fingers to project the navigation onto the top of the third screen 3, or by long-pressing the switch button on the third screen 3), the third screen 3 will switch to full-screen navigation regardless of whether it is on the lyrics page or the rearview camera page.

[0083] In this embodiment, a navigation three-screen interactive control method further includes: when full-screen navigation is displayed on the instrument panel 2, in response to detecting that the vehicle screen 4 has switched back to desktop 1 (e.g., the user switches back to the desktop via touch), the instrument panel 2 is notified to exit full-screen navigation and return to the page before the full-screen navigation was entered on the instrument panel 2.

[0084] In this embodiment, a navigation three-screen interactive control method further includes: when full-screen navigation is displayed on the third screen 3, in response to detecting that the vehicle screen 4 has switched back to the desktop, notifying the third screen 3 to exit full-screen navigation and return to the page before the third screen 3 entered full-screen navigation.

[0085] like Figure 1As shown in this embodiment, a navigation three-screen interactive control system includes a vehicle-mounted unit 1, a vehicle-mounted unit screen 4, an instrument panel screen 2, and a third screen 3, all connected to the vehicle-mounted unit 1. The vehicle-mounted unit 1 stores a computer-readable program, which, when invoked, can execute the steps of the navigation three-screen interactive control method as described in this invention.

[0086] In this embodiment, the computer-readable program is hereinafter referred to as including three functional modules: the instrument panel control module 5, the navigation application module 7, and the third screen content management service module 6. The instrument panel control module 5 is responsible for instrument content management, judgment and execution of interactive scenarios; the navigation application module 7 is used to pre-create three map instances for projection display on the three screens respectively, with the vehicle system 1 map instance running in the foreground by default, and the other two map instances running in the background; the third screen content management service module 6 is used to manage the content of the third screen 3.

[0087] The in-vehicle infotainment system contains various software applications, including navigation, audio-visual, and settings apps. The instrument panel control module 5, navigation application module 7, and third-screen content management service module 6 all run within it. After the system boots up, two desktops are displayed: desktop one is the default navigation interface, and desktop two is the entry point for other audio-visual apps. The system settings include a switch for the automatic multi-screen function, controlling whether this function is enabled.

[0088] Instrument panel: Used to implement the pages and content displayed on the instrument panel 2. It can also receive CAN signal commands output by the instrument panel control module 5, and receive navigation screens sent by the vehicle unit 1 through MIPI video stream for full-screen display.

[0089] Third screen: Used for the specific implementation of the third screen display pages and content. It can also receive screen projection instructions from the third screen content management service module 6 and receive video streams transmitted by the vehicle unit 1 via the LVDS protocol for page display in various screen projection applications.

[0090] Vehicle infotainment screen 4: Arranged side-by-side with the instrument panel screen 2, it is located in the middle of the instrument panel, to the right of the instrument panel screen 2. Vehicle infotainment screen 4 is responsible for displaying the page displays of all software on the vehicle infotainment system 1.

[0091] The instrument panel control module is a software module running on the vehicle's infotainment system. It is responsible for determining interactive scenarios, executing interactive behaviors, and managing the content projected onto the instrument panel 2. After the vehicle's infotainment system starts up, the instrument panel control module 5 determines the status of the automatic multi-screen interaction switch for navigation. If the automatic multi-screen interaction switch is off, neither the instrument panel 2 nor the third screen 3 will execute any automatic multi-screen interaction logic. If the automatic multi-screen interaction switch is on, it further determines whether the navigation application module 7 has initiated navigation. If navigation has not been initiated, no automatic multi-screen interaction processing is performed. If navigation has been initiated, it constantly checks the application status on the vehicle's infotainment system 1 and prepares to schedule multi-screen interaction. For example, if a long-running application is open on the vehicle's infotainment system (video playback applications such as Changba / Kugou Changchang / iQiyi / File Manager - local video playback pages are displayed on the front end of the vehicle's infotainment system, regardless of whether they are paused or playing), the instrument panel control module 5 determines that such an application has been started and is on the front end of the vehicle's infotainment screen 4. It then sends this information to the instrument panel via the CAN bus. After receiving the information, the instrument panel calls the navigation MIPI video stream to realize map navigation on the instrument panel 2.

[0092] The third-screen content management service module is a software module running in the vehicle's infotainment system. It manages the content of the third screen (3) and receives interface signals from the instrument panel control module to determine which application content should be projected onto the third screen (3). When a short-term application is opened on the vehicle's infotainment system (not on the list of apps on desktop 1 / 2, such as imaging, air conditioning, lighting, EaglePilot, Bluetooth phone, or Xiaoou voice assistant, etc., which are not video playback pages), the instrument panel control module (5) determines that this type of application is running and in the foreground of the vehicle's infotainment screen (4). It then transmits this information to the third-screen content management service module (6), which calls the navigation LVDS video stream to achieve full-screen navigation display on the third screen (3).

[0093] Navigation application module: Used to create three map instances, each for display on three screens.

[0094] When the vehicle is powered on, the vehicle infotainment system 1 starts up, along with the instrument cluster screen 2, the third screen 3, and the infotainment system screen 4, all of which are now operational. Simultaneously, the instrument panel control module 5, the third screen content management service module 6, and the navigation application module 7, all running on the vehicle infotainment system 1, also start up and begin operation. At this point, the system awaits user interaction with the vehicle infotainment system 1. When the user opens a long-used application on the vehicle infotainment system 1, this application is brought to the foreground of the infotainment system screen 4. Since the instrument panel control module 5 monitors applications appearing on the foreground of the infotainment system screen 4 in real time, this application will be detected by the instrument panel control module 5. Based on the preset interaction scenario and adhering to the principle that only one screen (instrument cluster screen 2, infotainment system screen 4, and third screen 3) can support full-screen navigation at any given time, the module will make a decision and control the relevant modules to respond accordingly.

[0095] In this embodiment, the interaction scenario determination mainly includes the following situations:

[0096] Scenario 1: When a user opens an application (e.g., an application displayed on the vehicle's infotainment screen 4 automatically triggered by a driver or passenger or certain driving operations, such as a panoramic / reversing camera), the instrument panel control module 5 determines whether the automatic multi-screen interaction switch for navigation is turned on. If it is not turned on, the automatic screen projection function is not activated, and the system does not perform the automatic screen projection action.

[0097] Scenario 2: When a user opens an application, the dashboard control module 5 determines whether the automatic multi-screen interaction switch for navigation is turned on. If it is turned on, it determines whether to initiate navigation. If navigation is not initiated, the automatic screen casting function is not activated, and the system does not perform the automatic screen casting action.

[0098] Scenario 3: When a user opens an application, the dashboard control module 5 determines whether the automatic multi-screen interaction switch for navigation is enabled. If it is enabled, it determines whether to initiate navigation. If navigation is initiated, it indicates that the automatic screen casting function is activated. At this time, the system performs the corresponding logical judgment and navigation screen casting according to the method described in this embodiment.

[0099] For example, after the system's automatic screen projection function is activated, if the instrument panel control module 5 determines that the vehicle's infotainment system 1 is running a long-term application (such as: Changba, Kugou Changchang, iQiyi, or the playback page of the file manager - local video displayed on the front of the vehicle's infotainment system 1, regardless of whether it is paused or playing), then it will notify the instrument panel 2 of the determination result through the CAN signal. The instrument panel 2 will then call the navigation video information through the MIPI video stream and perform full-screen navigation display.

[0100] For example, after the system's automatic screen projection function is activated, the instrument panel control module 5 determines that the vehicle's infotainment system 1 is using a short-term application (such as other pages that are not on desktop 1 / 2, such as images, air conditioning, lights, EaglePilot, Bluetooth phone, Xiaoou voice, etc., which are not video playback pages). The determination result is sent to the third screen content management service module 6 through the interface information. The third screen content management service module 6 calls the navigation information through the LVDS video stream, so that the third screen 3 can display full-screen navigation.

[0101] The entire navigation three-screen interactive control system divides the applications on the vehicle's infotainment system (VIS1) into two main categories: long-term and short-term applications. It fully utilizes the display functions of the instrument cluster screen (Screen 2) and the third screen (Screen 3). When the VIS1 is in navigation mode and music or other applications are played, the system automatically projects the navigation onto the instrument cluster screen (Screen 2) or the third screen (Screen 3) according to preset rules. This allows the driver to conveniently view navigation guidance while driving and easily operate other applications on the VIS, while also facilitating the use of other applications (such as entertainment applications) by other passengers, thus catering to the diverse information needs of both the driver and passengers.

[0102] In this embodiment, a vehicle employs a navigation three-screen interactive control system as described in this embodiment.

[0103] In this embodiment, a storage medium stores a computer-readable program, which, when invoked, can execute the steps of the navigation three-screen interactive control method described in this embodiment.
