Description

Technical Field

[0001] This application relates to the field of intelligent vehicle technology, and in particular to a distributed display method, a readable medium, and an in-vehicle device. Background Technology

[0002] With the rise of connected vehicles, people's demands for in-car entertainment are constantly increasing, and more and more passenger cars support multi-screen displays to provide a rich audio-visual experience. Furthermore, multi-screen displays also support distributed display functionality; for example, an application displayed on screen A can be launched and displayed on screen B.

[0003] For example, such as Figure 1 As shown, vehicle 11 supports three displays: display 100-1, display 100-2, and display 100-3. Display 100-1 can be the central control screen on vehicle 11, display 100-2 can be the display on the passenger seat of vehicle 11, and display 100-3 can be the display on the rear seat of vehicle 11.

[0004] For example, an application displayed on display screen 100-1 can be launched and displayed on display screen 100-2, such as... Figure 2A As shown, the driver can click the "Navigation" icon on the display interface 101 of the display screen 100-1. A small window 102 will pop up on the display interface 101 of the display screen 100-1, where the driver can select which display screen the "Navigation" application will be launched and displayed on. For example, as... Figure 2B As shown, the driver taps the button on the passenger-side screen to launch the "Navigation" application and display it on display screen 100-2. For example, as... Figure 2C As shown, the "Navigation" application is launched and displayed on screen 100-2.

[0005] Although drivers can manually launch applications on display screen 100-1 and display them on display screen 100-2, when the vehicle is in motion, drivers need to operate the controls while driving, which can easily lead to driver distraction and poses a significant safety hazard. Therefore, how to support multi-screen interaction while reducing driver operation and avoiding driver distraction has become an urgent problem to be solved for vehicle multi-screen interactive displays.

[0038] The illustrative embodiments of the present application include, but are not limited to, methods, readable media, and electronic devices.

[0039] To solve the above technical problems, the present application provides a distributed display method, which is applied to a vehicle-mounted device. The vehicle-mounted device can detect the position of a user in a vehicle cabin and determine which display screen of a vehicle 11 to display a to-be-started application according to the position of the user.

[0040] Further, the vehicle-mounted device can also acquire biological feature information of the user and determine the position of the user in the vehicle cabin, and determine which display screen of the vehicle 11 to display the to-be-started application according to the biological feature information of the user, the position of the user in the vehicle cabin, and the number of times that the user uses the to-be-started application corresponding to the biological feature information of the user in the past period of time.

[0041] As an exemplary, Figure 3AAs shown, the in-vehicle device detects the user's activation of the "Navigation" application on display screen 100-1, and the in-vehicle device determines the user's location in the passenger compartment as the front passenger seat; based on the user's location in the passenger compartment, the in-vehicle device displays the "Navigation" application interface on display screen 100-2 on the front passenger seat (e.g., Figure 3B (As shown).

[0042] To make the purpose, technical solution, and advantages of this application clearer, the following is in conjunction with... Figures 1-12 The technical solution of this application is described in detail.

[0043] Figure 4 According to an embodiment of this application, a schematic diagram of a distributed display scenario is shown, the scenario including: vehicle 11; wherein, vehicle 11 is equipped with multiple vehicle-mounted devices, namely vehicle-mounted device 10-1, vehicle-mounted device 10-2, ..., vehicle-mounted device 10-n.

[0044] like Figure 4 As shown, each in-vehicle device includes a display screen. For example, in-vehicle device 10-1 includes display screen 100-1, in-vehicle device 10-2 includes display screen 100-2, ..., in-vehicle device 10-n includes display screen 100-n. The display interfaces of display screens 100-1 to 100-n can display the same in-vehicle application or different in-vehicle applications.

[0045] In the embodiments of this application, the operating system that can run on vehicle-mounted device 10-1, vehicle-mounted device 10-2, ..., vehicle-mounted device 10-n can be any of the following operating systems: HarmonyOS. operating system, operating system, Operating systems, MAC operating systems, etc. The operating systems running on vehicle-mounted devices 10-1, 10-2, ..., 10-n can be the same or different. This application does not specifically limit whether the operating systems running on vehicle-mounted devices 10-1, 10-2, ..., 10-n are the same, depending on the actual application requirements.

[0046] In some embodiments, the distributed display is achieved through communication connection between the plurality of in-vehicle devices, for example, the plurality of in-vehicle devices can be connected through wireless communication network such as wireless local area networks (WLAN) (e.g. wireless fidelity (Wi-Fi) network), bluetooth (BT), near field communication (NFC) and the like.

[0047] It can be understood that, for example, Figure 1 The three display screens shown on the vehicle 11 can be display screens respectively deployed on the three in-vehicle devices, and the distributed display is achieved through communication between the three in-vehicle devices. It can be understood that the application displayed on the display interface of the display screen on any in-vehicle device can be displayed on the in-vehicle device itself or on other in-vehicle devices. For example, the application displayed on the display interface of the display screen of the in-vehicle device 10-1 can be displayed on the display screen of the in-vehicle device 10-1, the display screen of the in-vehicle device 10-2 or the display screen of the in-vehicle device 10-n.

[0048] Hereinafter, an example is described in which the vehicle 11 is installed with three in-vehicle devices, i.e. the in-vehicle device 10-1, the in-vehicle device 10-2 and the in-vehicle device 10-3, and the display content of the application on the in-vehicle device 10-1 is displayed on the display screen 100-2.

[0049] Figure 5 For embodiments according to the present application, a flowchart of a distributed display is shown; as shown in Figure 5 As shown, the distributed display process includes:

[0050] S501: The in-vehicle device 10-1 detects an operation of starting the "navigation" application, wherein the "navigation" application icon is displayed on the display screen 100-1 of the in-vehicle device 10-1.

[0051] In some embodiments, the in-vehicle device 10-1 can detect an operation of the user starting the "navigation" application on the display screen 100-1, wherein the "navigation" application is displayed on the display screen of the in-vehicle device 10-1.

[0052] For example, as shown in the display screen 100-1 on the vehicle 11 in FIG. 3, the user can start the application displayed on the display screen 100-1 through operation modes such as touch, gesture, voice and the like. For example, as shown in Figure 3A As shown, the user can click the "navigation" icon on the display interface of the display screen 100-1, at which time the in-vehicle device 10-1 can detect the operation of the user starting the "navigation" application.

[0053] It can be understood that the user can also start the application displayed on the display screen 100-2 of the vehicle-mounted device 10-2 by touch, gesture, voice, etc. The user can also start the application displayed on the display screen 100-3 of the vehicle-mounted device 10-3 by touch, gesture, voice, etc. Hereinafter, the operation that the vehicle-mounted device 10-1 detects that the user starts the "navigation" application displayed on the display screen 100-1 of the vehicle-mounted device 10-1 is taken as an example for description.

[0054] S502: The vehicle-mounted device 10-1 acquires the position of the user in the vehicle cabin.

[0055] In some embodiments, the vehicle-mounted device 10-1 can determine the position of the user in the vehicle cabin according to the data collected by the sensor arranged in the vehicle cabin. The sensor can be an image sensor (for example, a camera), and can also be an infrared sensor, an ultrasonic sensor, a laser radar sensor, etc.

[0056] For example, the vehicle-mounted device 10-1 can determine that the user is on the main driver's seat according to the data collected by the sensor on the device itself. The vehicle-mounted device 10-1 can also determine that the user is on the co-driver's seat or the back seat according to the data collected by the sensor of the vehicle-mounted device 10-2 or the vehicle-mounted device 10-3 sent by the vehicle-mounted device 10-2 or the vehicle-mounted device 10-3.

[0057] In other embodiments, the vehicle-mounted device 10-2 or the vehicle-mounted device 10-3 can determine that the user is on the co-driver's seat or the back seat according to the data collected by the sensor on the device itself. The vehicle-mounted device 10-2 or the vehicle-mounted device 10-3 sends the information that the user is on the co-driver's seat or the back seat to the vehicle-mounted device 10-1, and the vehicle-mounted device 10-1 acquires the position of the user in the vehicle cabin.

[0058] In other embodiments of the present application, the vehicle-mounted device 10-1 can determine the position of the user in the vehicle cabin according to the sound source information of the user collected by the microphone arranged in the vehicle cabin. The vehicle-mounted device 10-1 can also determine the position of the user in the vehicle cabin according to the sound source information of the user collected by the microphone arranged in the vehicle cabin. The specific content of the source of the sound source information of the user acquired by the vehicle-mounted device 10-1 is referred to the content of the data collected by the sensor arranged in the vehicle cabin, which is not described here.

[0059] S503: The vehicle-mounted device 10-1 determines the display screen on which the display content of the "navigation" application is displayed according to the position of the user in the vehicle cabin.

[0060] For example, the vehicle-mounted device 10-1 acquires that the position of the user in the vehicle cabin is the co-driver's seat. When detecting that the user starts the "navigation" application of the vehicle-mounted device, the vehicle-mounted device 10-1 determines that the display content of the "navigation" application is displayed on the display screen 100-2.

[0061] For example, the in-vehicle device 10-1 can also acquire the position of the user in the vehicle cabin as the front passenger seat, the driver seat, and the back seat, respectively, and determine that the display content of the "navigation" application is displayed on the display screen 100-1, the display screen 100-2, and the display screen 100-3.

[0062] S504: The in-vehicle device 10-1 displays the display interface of the "navigation" application on the display screen 100-2.

[0063] For example, as shown in Figure 3B , the in-vehicle device 10-1 can start and display the "navigation" application on the display screen 100-2 of the in-vehicle device 10-2. The specific content of the in-vehicle device 10-1 starting and displaying the "navigation" application on the display screen 100-2 of the in-vehicle device 10-2 is described in detail below in combination with the software architecture of the in-vehicle device 10-1 and the in-vehicle device 10-2, which is not repeated here.

[0064] It can be understood that the in-vehicle device 10-2 or the in-vehicle device 10-3 can also acquire the position of the user in the vehicle cabin and determine which display screen in the vehicle cabin to display the application on the in-vehicle device 10-2 or the in-vehicle device 10-3. The specific content is described with reference to Figure 5 , which is not repeated here.

[0065] As can be known from the description process of Figure 5 , the in-vehicle device 10-1 can acquire the position of the user in the vehicle cabin, and in the case of detecting that the user starts the application on the in-vehicle device 10-1, the in-vehicle device 10-1 determines which display screen in the vehicle cabin to display the application on the in-vehicle device 10-1. Thus, in the case that the user performs an operation (for example, Figure 2B ) on the "navigation" application on the display screen, the display content of the "navigation" application can be displayed on the display screen 100-2, thereby reducing the redundant operation of the user and improving the user experience.

[0066] In other embodiments of the present application, the in-vehicle device can also acquire the biometric information of the user in the vehicle cabin, and determine which display screen in the vehicle cabin to display the "navigation" application according to the position of the user in the vehicle cabin and the biometric information of the user in the vehicle cabin.

[0067] Figure 6 For embodiments according to the present application, another flowchart of distributed display is shown; as shown in Figure 6 , the distributed display process includes:

[0068] S601: The in-vehicle device 10-1 detects an operation of starting the "navigation" application, wherein the "navigation" application icon is displayed on the display screen 100-1 of the in-vehicle device 10-1. The specific content is described with reference toFigure 5 The step S501 is not repeated here.

[0069] S602: The in-vehicle device 10-1 acquires the position of the user in the vehicle cabin. For details, refer to the step S502 of the method 500. Figure 5 The step S502 is not repeated here.

[0070] S603: The in-vehicle device 10-1 acquires the biometric information of the user in the vehicle cabin. The in-vehicle device 10-1 can identify the user in the vehicle cabin according to the biometric information of the user.

[0071] In some embodiments, the biometric information of the user includes face information, voiceprint information, fingerprint information, iris information, etc. The in-vehicle device 10-1 can identify whether the user in the vehicle cabin is the user A or the user B according to the biometric information of the user.

[0072] In some embodiments, the in-vehicle device 10-1 can perform the step S602, and then the in-vehicle device 10-1 acquires the biometric information of the user at the position according to the position of the user in the vehicle cabin, so as to identify the user at the position.

[0073] Taking the face information as an example, the in-vehicle device 10-1 can acquire the image data of the user sitting on the driver seat or other seats through the camera arranged in the vehicle cabin, acquire the face information according to the image data, and identify the user sitting on the driver seat or other seats. The in-vehicle device 10-1 can also acquire the face information of the user on the driver seat or other seats sent by the in-vehicle device 10-2 or the in-vehicle device 10-3, and identify the user sitting on the driver seat or other seats.

[0074] It can be understood that the camera for collecting the image data in the vehicle cabin can be the camera on the in-vehicle device 10-1, which can be installed on the display screen 100-1. The camera for collecting the image data in the vehicle cabin can also be the camera on the in-vehicle device 10-2 or the in-vehicle device 10-3, which can send the image data collected by the camera to the in-vehicle device 10-1. According to the actual application, the position of the data collection device (for example, the camera, the microphone, the fingerprint sensor) where the in-vehicle device 10-1 acquires the biometric information of the user in the vehicle cabin is not limited.

[0075] S604: The in-vehicle device 10-1 determines the display screen for displaying the display content of the "navigation" application according to the position of the user in the vehicle cabin, the biometric information of the user, and the number of times that the user uses the "navigation" application corresponding to the biometric information of the user in the past period of time.

[0076] In some embodiments, the in-vehicle device 10-1 can save the number of times each user uses each application on the in-vehicle device 10-1 in the past period of time, determine which display screen in the vehicle cabin to display the "navigation" application according to the number of times of use, the position of the user in the vehicle cabin, and the biometric information of the user.

[0077] For example, the number of times user A uses the "navigation" application in the past 10 days is 100, the number of times user B uses the "navigation" application in the past 10 days is 50, the in-vehicle device 10-1 obtains that user A is on the front passenger seat and user B is on the back seat, and then the in-vehicle device 10-1 displays the display content of the "navigation" application on the display screen 100-2 when detecting that the user starts the application on the in-vehicle device 10-1, because the user uses the application more frequently in the past 10 days.

[0078] S605: The in-vehicle device 10-1 displays the display interface of the "navigation" application on the display screen 100-2. For details, refer to the description of step S505, which will not be repeated here.

[0079] It can be understood that the in-vehicle device 10-2 or the in-vehicle device 10-3 can also obtain the position of the user in the vehicle cabin and the biometric information of the user to determine which display screen in the vehicle cabin to display the application on the in-vehicle device 10-2 or the in-vehicle device 10-3. For details, refer to the description of Figure 6 the display content, which will not be repeated here.

[0080] As can be known from the description process of Figure 6 , the in-vehicle device 10-1 can obtain the position of the user in the vehicle cabin and the biometric information of the user, and determine which display screen in the vehicle cabin to display the "navigation" application according to the position of the user in the vehicle cabin and the biometric information of the user in the vehicle cabin. It can be understood that the in-vehicle device 10-1 can display the application frequently used by the user on the display screen of the seat where the user is located according to the habit of the user using the application, after determining the identity and position of the user in the vehicle cabin. Thus, the application can be displayed on the display screen desired by the user without additional operation of the user, thereby improving the user experience.

[0081] Figure 7 For another distributed display process according to the embodiments of the present application, a flowchart is shown as Figure 7 shown, the distributed display process includes:

[0082] S701: The in-vehicle device 10-1 detects an operation of starting the "navigation" application, wherein the "navigation" application icon is displayed on the display screen of the in-vehicle device 10-1. For details, refer to step S501 of Figure 5 , which will not be repeated here.

[0083] S702: The in-vehicle device 10-1 determines the display screen 100-2 that displays the display content of the "navigation" application according to the preset association relationship between the "navigation" application and the display screen 100-2.

[0084] For example, the in-vehicle device 10-1 can display the display interface of the "navigation" application on the display screen 100-2 according to the preset association relationship between the "navigation" application and the display screen 100-2.

[0085] In some embodiments, the in-vehicle device can create the association relationship between the application and the display screen according to the association operation of the user on the in-vehicle device; for example, the user can perform the association operation on the "navigation" application and the display screen 100-2 in the "setting" application of the in-vehicle device, and the in-vehicle device generates the association relationship between the "navigation" application and the display screen 100-2 in response to the association operation.

[0086] In other embodiments, the electronic device and the in-vehicle device establish a communication connection, and the electronic device can install an application for managing the association relationship between the in-vehicle application and the display screen; the in-vehicle device can create the association relationship between the application and the display screen according to the association operation of the user on the electronic device; for example, the electronic device can install a "vehicle pass" application (APP), and the user can perform the association operation on the "navigation" application and the display screen 100-2 in the "vehicle pass" application of the electronic device, and the in-vehicle device generates the association relationship between the "navigation" application and the display screen 100-2 in response to the association operation.

[0087] It can be understood that the "navigation" application can also be associated with the display screen 100-3, and the "navigation" application can also be associated with the display screen 100-1; the association relationship between the application on the in-vehicle device 10-1 and the display screen in the vehicle 11 is not limited in the present application.

[0088] S703: The in-vehicle device 10-1 displays the display interface of the "navigation" application on the display screen 100-2. For details, refer to step S504 of Figure 5 , which will not be repeated here.

[0089] It can be understood that the in-vehicle device 10-2 or the in-vehicle device 10-3 can also determine which display screen in the vehicle cabin to display the application on the in-vehicle device 10-2 or the in-vehicle device 10-3 according to the association relationship between the application on the in-vehicle device 10-2 or the in-vehicle device 10-3 and the display screen in the vehicle cabin set by the user in advance. For details, refer to the description of Figure 5 , which will not be repeated here.

[0090] From the description process of Figure 7 , it can be known that the vehicle-mounted device 10-1 can determine which display screen in the vehicle cabin the application on the vehicle-mounted device 10-1 is displayed on according to the association relationship between the application on the vehicle-mounted device 10-1 and the display screen in the vehicle cabin pre-set by the user, in the case that the vehicle-mounted device 10-1 detects that the user starts the application on the vehicle-mounted device 10-1. Thus, the application on the vehicle-mounted device 10-1 is displayed on the display screen desired by the user without additional operation of the user, improving the user experience.

[0091] The process of the vehicle-mounted device 10-1 creating the association relationship between the application and the display screen in step S702 of Figure 7 will be described in detail below.

[0092] In some embodiments, the association relationship between the application on the vehicle-mounted device 10-1 and the display screen in the vehicle cabin can be saved in a static rule set.

[0093] For example, as shown in Figure 8 , the static rule set can include the association relationship between a single application and a display screen, and the association relationship between an application set and a display screen. The application set represents a collection containing multiple applications with similar functions; for example, the “instant messaging” application set can include the “message” application, the “ ” application, the “ ” application, etc., and if the “instant messaging” application set establishes an association relationship with a display screen, it means that each application in the “instant messaging” application set establishes an association relationship with the display screen.

[0094] In some embodiments, the static rule set of the application contains the association relationship between the application or the application set and the display screen, which can make the vehicle-mounted device 10-1 start and display the application on the display screen having the association relationship with the application when the vehicle-mounted device 10-1 detects that the application in the static rule set is started.

[0095] For example, as shown in Figure 3A , the applications displayed on the display screen 100-1 include: “navigation”, “music”, “video”, “audiobook”, and the “instant messaging” application set, etc., wherein the “instant messaging” application set includes the “ ” application, the “message” application, and the “ ” application.
