[0040] It should be noted that during the ride, if passengers want to enjoy in-car entertainment and comfort control without interfering with the driver's screen use, they mainly use additional in-car hardware sub-screens. However, adding additional in-car hardware screens will increase the manufacturing cost and design complexity of the vehicle, especially high-end models may require high-resolution, multi-touch screens.

[0041] Based on this, an embodiment of the present invention provides an application display method, which is applied to a vehicle, wherein the vehicle is integrated with a control system, and the control system is configured with a network web service and a wireless WiFi hotspot. Figure 1 A flowchart of an application display method provided in an embodiment of the present invention. The embodiment of the present invention can be applied to a scenario in which passengers control and use an in-vehicle entertainment application in an in-vehicle entertainment system through a display terminal. The method can be executed by a control system, and the control system can be implemented in the form of software and / or hardware configured on the vehicle.

[0042] like Figure 1 As shown, the application display method provided by the embodiment of the present invention may specifically include:

[0043] S101. After detecting that communication is established with at least one display terminal via a WiFi hotspot, obtain pre-configured virtual screen information, and generate a virtual screen interface according to the virtual screen information, wherein the virtual screen information includes: screen attribute information of the virtual screen and application attribute information of the vehicle-mounted application contained in the screen.

[0044] Among them, the display terminal can be understood as a non-vehicle device with display function that can connect to a WiFi hotspot, such as a mobile phone, a tablet, etc. The virtual screen interface can be understood as an interface generated by software in the in-vehicle entertainment system, which is used to display the application functions and various information in the in-vehicle entertainment system without relying on the actual physical screen, wherein the in-vehicle entertainment system can be used as a subsystem under the control system to manage and control the entertainment applications on the vehicle. The virtual screen information can be understood as a series of parameters and settings for defining and configuring the virtual screen interface, including the screen attribute information of the virtual screen interface and the application attribute information of the in-vehicle application contained in the screen; the screen attribute information can be considered as a parameter that defines the appearance and performance of the virtual screen, including a collection of information such as the virtual screen pixel resolution, physical size, display area size, the number of colors that can be displayed, refresh frequency, and aspect ratio; the application attribute set can be understood as the relevant information of the application, including the application name, version number, claim requirements, configuration settings (such as language, theme, etc.) of the application.

[0045] In this embodiment, when the in-vehicle entertainment system detects that communication has been successfully established with at least one display terminal through the WiFi hotspot, it obtains pre-configured virtual screen information that matches the display terminal, and generates a virtual screen interface based on the obtained virtual screen information. The virtual screen interface will display the interface and functions of the in-vehicle entertainment application, and will be adapted to the display habits and usage habits of the display terminal.

[0046] Exemplarily, when the display terminal is a mobile phone, the corresponding aspect ratio included in the corresponding pre-configured virtual screen information may be 16:9.

[0047] For example, the in-vehicle entertainment applications displayed on the virtual screen interface may include music, movies, seat massage, fragrance, and other functions that do not affect driving.

[0048] S102, transmitting the virtual screen interface to the web service, and transmitting the first interface content of the virtual screen interface to the web page displayed on the display terminal through the web service, the web page is generated based on a pre-assigned network address, and the network address is assigned after establishing communication with the corresponding display terminal.

[0049] The first interface content can be understood as the content initially presented on the virtual screen interface. The web service can be understood as a software system that provides web applications, which is used to ensure that cross-network application programs can interact with each other.

[0050] In this embodiment, the virtual screen interface is transmitted in real time to a web service, such as a vehicle-mounted lightweight web service, and through the web service, the first interface content of the virtual screen interface is transmitted to the web page displayed by the display terminal. The web page needs to be generated based on the network address assigned to the display terminal by the vehicle-mounted entertainment system after establishing communication with the display terminal.

[0051] An application display method provided by an embodiment of the present invention obtains pre-configured virtual screen information after detecting that communication is established with at least one display terminal through a WiFi hotspot, and generates a virtual screen interface according to the virtual screen information; transmits the virtual screen interface to a web service, and transmits the first interface content of the virtual screen interface to a web page displayed on the display terminal through the web service. The technical solution of the embodiment of the present invention customizes and generates a virtual screen interface according to the virtual screen information, ensuring that the first interface content can be synchronously and correctly displayed and run on different display terminals, and by transmitting the first interface content of the virtual screen interface to a web page displayed on the display terminal, the vehicle body hardware cost and the occupation of empty space in the vehicle are reduced, and the convenience of application display is improved. At the same time, the display terminal is provided with entertainment functions that are strongly associated with the vehicle body hardware, and the feasibility of flexibly accessing more web resources to update and expand entertainment application functions is further improved. User experience.

[0052] As a first optional embodiment of this embodiment, on the basis of the above embodiment, the virtual screen interface can be transmitted to the web service, and the first interface content of the virtual screen interface can be transmitted to the web page displayed on the display terminal through the web service, which is specifically implemented as the following steps:

[0053] a1) performing video encoding on the virtual screen interface, and transmitting the generated first video code stream to the web service.

[0054] The first video code stream may be understood as a video code stream formed by performing video encoding on the content initially presented on the virtual screen interface.

[0055] In this embodiment, the initial content presented by the virtual screen interface is encoded in real time to form a first video code stream, and the formed first video code stream is transmitted to the web service. Exemplarily, the transmission can be performed via websocket.

[0056] Exemplarily, the first video code stream may be an H264 video code stream, and the video encoding may be performed using MediaCodecAPI.

[0057] b1) transmitting the first video code stream to the display terminal through the web service, decoding the first video code stream through the display terminal, obtaining the first interface content of the decoded virtual screen interface, and presenting the first interface content on the web page corresponding to the web service through the browser on the display terminal.

[0058] In this embodiment, the first video code stream is transmitted to the browser of the display terminal through a web service via Http or websocket, the received first video code stream is decoded in the display terminal, the first interface content of the decoded virtual screen interface is obtained, and the first interface content is presented on the web page corresponding to the web service through the browser on the display terminal.

[0059] The above technical solution of this embodiment transmits the first video code stream to the display terminal through the web service in real time, obtains the first interface content of the virtual screen interface by decoding the first video code stream, and presents the first interface content through the browser on the display terminal, thereby realizing the synchronous, correct display and operation of the first interface content on different display terminals, avoiding the need for the display terminal to pre-install additional plug-ins or applications, and improving the convenience of application display.

[0060] As a second optional embodiment of this embodiment, based on the above embodiment, it also includes:

[0061] a2) After detecting that the WiFi hotspot is turned on, if a display terminal requesting access is captured, when it is determined that the current access volume has not reached a set upper limit, it is determined that the display terminal has access authority and access inquiry information is sent to the display terminal.

[0062] Among them, the current access volume can be considered as the number of display terminals currently connected to the WiFi hotspot opened by the control system; the access inquiry information can be understood as a message used to confirm whether the display terminal wants to access the WiFi hotspot, and the access inquiry information may include a request to enter a WiFi password.

[0063] In this embodiment, when it is detected that the control system has turned on the WiFi hotspot, the display terminal requesting access is captured in real time. If a display terminal requesting access is captured, it is determined whether the current access volume has reached the set upper limit of the access volume. If the current access volume has not reached the set upper limit, it is determined that the display terminal currently captured requesting access has access authority, and access inquiry information is sent to the display terminal.

[0064] It should be noted that the WiFi hotspot is configured in advance in the control system through an operating system such as a Linux system, an Android system, etc., and whether a WiFi password needs to be entered is set. If necessary, an initial WiFi password is set, and the dynamic host configuration protocol service is enabled.

[0065] b2) after receiving the access authentication information fed back by the display terminal in response to the access inquiry information, establishing a communication connection with the display terminal and allocating a network address for web access to the display terminal.

[0066] The access authentication information may be understood as the authorization information, identity authentication information, etc. fed back by the display terminal.

[0067] In this embodiment, after receiving the access authentication information fed back by the display terminal in response to the query information and passing the verification, a communication connection is established with the display terminal, and a network address for accessing the web page is allocated to the display terminal through the dynamic host configuration protocol service.

[0068] Exemplarily, when no password is required to connect to the WiFi hotspot turned on by the control system, the access inquiry information sent to the display terminal is whether to confirm the connection to this WiFi hotspot. After receiving the access authentication information feedback from the display terminal as yes and the local area network address of the display terminal, if the local area network address is verified to be valid, a communication connection is established with the display terminal, and a network address for web access is assigned to the display terminal.

[0069] Exemplarily, when a password is required to connect to the WiFi hotspot turned on by the control system, the access inquiry information sent to the display terminal is please enter the WiFi password. After receiving the access authentication information (i.e., WiFi password) fed back by the display terminal, if the access authentication information is verified to be valid, a communication connection is established with the display terminal, and a network address for web access is assigned to the display terminal.

[0070] It is understandable that the WiFi password can be obtained by asking the main driver, and the main driver can also change the WiFi password at any time.

[0071] The above technical solution of this embodiment captures the display terminal requesting access, sends access inquiry information to the display terminal after determining that the display terminal has access authority, establishes a communication connection with the display terminal after receiving the access authentication information fed back by the access inquiry information, and allocates a network address for web access to the display terminal, thereby ensuring the effective management of the number of connected devices and enabling the display terminal to access web services through the network address.

[0072] As one implementation method, based on this optional embodiment, it also includes:

[0073] a3) receiving a web access request sent by the display terminal through the network address through the started web service.

[0074] It should be noted that before capturing the display terminal that requests access, the web service of the in-vehicle entertainment system needs to be enabled through the in-vehicle screen.

[0075] In this embodiment, when the display terminal sends a web access request through the network address, the started web service will receive the web access request.

[0076] b3) determining a login interface corresponding to the web access request and transmitting it to the display terminal so as to be displayed through the browser of the display terminal.

[0077] In this embodiment, the web service determines a corresponding login interface to be displayed according to the web access request, transmits the login interface to the display terminal, and displays the login page through the browser of the display terminal.

[0078] c3) after determining that the login authentication information input by the display terminal through the login interface is correct, generating a web page for virtual screen display, and transmitting the web page displayed on the browser to the display terminal.

[0079] The login authentication information may be understood as authentication information for accessing the web page displayed corresponding to the virtual screen interface, such as a password, etc.

[0080] In this embodiment, after the display terminal enters the login authentication information through the login interface and submits it, if the web service determines that the login authentication information is correct, it generates a web page for displaying the virtual screen interface presented by the virtual screen, and sends the web page to the display terminal. The web page will be displayed on the browser of the display terminal.

[0081] The above technical solution of this embodiment, after receiving the web access request sent by the display terminal through the network address through the started web service, provides a login interface corresponding to the web access request to the display terminal, and after confirming that the login authentication information is correct, generates a web page for virtual screen display and transmits it to the display terminal, so that the display terminal can display the virtual screen interface and the web application therein on the web page of the browser, thereby enabling the display terminal to interact with the virtual screen interface.

[0082] As a third optional embodiment of this embodiment, it also includes:

[0083] a4) According to the pre-configured application permissions, determine the in-vehicle applications that are allowed to be presented on the display terminal, and obtain application attribute information of each of the in-vehicle applications.

[0084] In this embodiment, application permissions are pre-configured for the display terminal, such as disabling navigation application permissions, enabling seat massage application permissions, etc. Based on the pre-configured application permissions, the in-vehicle applications allowed to be presented on the display terminal are determined, i.e., the in-vehicle applications with application permissions enabled, and application attribute information of each of the in-vehicle applications is obtained.

[0085] Exemplarily, the in-vehicle applications allowed to be presented on the display terminal may be displayed in the form of a list.

[0086] It is understandable that the pre-configured application permissions may be the initial default configuration of the in-vehicle entertainment system, or may be reconfigured in the in-vehicle screen according to specific needs.

[0087] b4) Determine screen attribute information of the virtual screen according to pre-configured role display management information.

[0088] Among them, the pre-configured role display management information can be understood as information for managing the screen display related feature information of the display terminals used by different roles. For example, the roles can be the main driver and passengers in the vehicle. The display terminal corresponding to the main driver can be the main screen in the vehicle. For another example, the display terminal corresponding to the passenger can be a mobile phone, a tablet, and a laptop computer. The role display management information may include screen size information adapted by different display terminals. Therefore, based on the screen size information, the appropriate screen size, clarity, and resolution can be determined for the virtual screen, and the determined information can constitute the screen attribute information of the virtual screen.

[0089] Exemplarily, when the display terminal is a mobile phone, the pre-configured character display management information can be based on the conventional screen characteristics of the mobile phone, such as an aspect ratio of 16:9, and the aspect ratio of the screen attribute information of the virtual screen is 16:9.

[0090] c4) Based on the application attribute information and the screen attribute information, construct and store the virtual screen information.

[0091] In this embodiment, the application attribute information and the screen attribute information are integrated to form the virtual screen information, and the virtual screen information is stored.

[0092] The above technical scheme of this embodiment, by determining the application attribute information of the in-vehicle application allowed to be presented on the display terminal and the screen attribute information of the virtual screen, constitutes and stores the virtual screen information, thereby ensuring that the display terminal only displays the application functions that are allowed to be used, ensuring the safety of using the in-vehicle entertainment application, and storing the virtual screen information improves the response speed of the application display and enhances the user experience.

[0093] As one implementation of any embodiment of the present invention, the method further includes:

[0094] a5) determining a target vehicle-mounted application through the web service according to the application operation information fed back by the display terminal.

[0095] The application operation information is generated by the display terminal according to the received screen touch event, and is used to describe the specific screen touch event of the display terminal. For example, the screen touch event may be to play a movie by clicking, to increase the massage intensity by sliding, etc. The target vehicle application may be understood as the vehicle application being operated by the display terminal.

[0096] Exemplarily, the application operation information may include coordinate information of a click on a web page received by the display terminal.

[0097] Exemplarily, the application operation information may also include the direction, distance, and coordinate information of the sliding web page received by the display terminal.

[0098] In this embodiment, the application operation information fed back by the display terminal is analyzed and processed through the web service, the target vehicle application is determined, and the processed application operation information and the determined target vehicle application are sent to the virtual screen interface.

[0099] Exemplarily, by calculating the coordinate information of the clicked web page received by the display terminal contained in the application operation information, the coordinate information of the web page is converted with the coordinate information of the virtual screen interface in the web service, thereby determining the target vehicle-mounted application.

[0100] b5) responding to the application execution logic of the target vehicle-mounted application, and transmitting the second interface content corresponding to the application execution logic response to the web page of the display terminal in the form of a second video code stream.

[0101] The application execution logic can be understood as the logical process of running the application code, processing the user request, and generating the corresponding output. The second interface content can be understood as the new interface generated after the virtual screen interface responds to the application execution logic. The second video code stream can be understood as the video code stream obtained after the second interface content is video encoded.

[0102] In this embodiment, the virtual screen responds to the application execution logic of the target vehicle-mounted application and generates second interface content based on the received processed application operation information and the determined target vehicle-mounted application, performs video encoding on the second interface content corresponding to the application execution logic response to obtain a second video stream, and then transmits the second video stream to the web page of the display terminal through the web service.

[0103] Exemplarily, the virtual screen receives application operation information and the determined target vehicle-mounted application by sending the coordinate-transformed application operation information and the determined target vehicle-mounted application to the Android screen touch event receiving module through websocket on the web service. The Android screen touch event receiving module performs touch operations on the virtual screen according to the application operation information and the determined target vehicle-mounted application. That is, the virtual screen receives the application operation information and the determined target vehicle-mounted application fed back by the display terminal.

[0104] The above-mentioned technical scheme of this embodiment determines the target vehicle-mounted application according to the application operation information fed back by the display terminal and responds to the application execution logic of the target vehicle-mounted application, and transmits the corresponding second interface content in the response to the web page of the display terminal in the form of a second video code stream, so that the virtual screen can respond to and execute the application operation of the display terminal, and the result after executing the application operation is synchronously and smoothly displayed on the display terminal.

[0105] In this specific embodiment, the implementation process of the application display method is given from the perspective of the display terminal. Specifically, Figure 2 This is a flow chart of an application display method provided in an embodiment of the present invention. The embodiment of the present invention can be applicable to a scenario in which passengers control and use an in-vehicle entertainment application in an in-vehicle entertainment system through a display terminal. The method can be executed by an in-vehicle application display device configured on the display terminal. The device can be implemented in the form of software and / or hardware, and optionally, can be implemented by an electronic device, which is preferably a mobile terminal, a desktop computer, a laptop computer, etc.
