Obviously, the drawings described below are some embodiments of the present application.

[0059] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0060] When some mobile devices, such as iOS phones, are in the screen-off state, locked state, or the application on the mobile terminal is switched to the background, the navigation screen will disappear immediately. The main reason for this problem is that map applications usually use the graphics processing unit (GPU) to draw the user interface (UI) and render the page as a map image. When the mobile terminal is in the screen-off state or locked state, when the application on the mobile terminal is switched to the background, the graphics processor on the mobile terminal stops working and no longer renders the page that the background application still needs to draw.

[0061] In some examples, when the mobile terminal is in the screen-off state or the screen-locked state and the application is switched to the background, the map image is abandoned and simple navigation data is transmitted to the electronic device through the mobile terminal to realize simple navigation information display on the electronic device, such as Figure 1 As shown, this method cannot realize road network navigation, such as Figure 2 As shown, the user visual experience is not good.

[0062] In addition, some applications, such as CarPlay, can realize navigation screen projection and achieve the effect of road network navigation by encoding and other processing according to specially designed technical specifications when the mobile terminal is unlocked and the application of the mobile terminal is in the foreground running state. However, the projection technology supported by its technical specifications has high hardware requirements for the projection object (such as the vehicle side). For example, the electronic device needs to have a minimum resolution of 800×480 or 710×570, the electronic device needs to support the digital video compression format of H264 and the supported encoding format of HEVC (High Efficiency Video Coding), and the electronic device needs to have audio input (such as microphone, etc.) and audio output (such as speakers, etc.). Therefore, these map display projection solutions are difficult to apply to low-cost hardware, such as electric two-wheeled vehicles, to realize the function of navigation screen projection.

[0063] To this end, the present application provides a map display method, which draws a map image by the central processing unit in the mobile terminal when the image processor in the mobile terminal stops drawing, thereby solving the problem that the image processor cannot draw the map image when the target application switches to background operation or the mobile terminal is in the screen-off or screen-locked state, so that the electronic device can display the map in real time.

[0064] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0065] Figure 3 FIG. 1 is a schematic diagram showing a scene of a map display method provided by an embodiment of the present application. Figure 3 As shown, a mobile terminal (such as a mobile phone, a tablet computer, etc.) 101 and an electronic device (such as an electric two-wheeled vehicle, an electric three-wheeled vehicle, etc., an electric two-wheeled vehicle such as an electric bicycle, an electric motorcycle, an electric scooter, etc.) 102 are configured with a wireless communication module (such as a Bluetooth communication module, a WiFi communication module), and a wireless communication connection can be established between the mobile terminal 101 and the electronic device 102.

[0066] After receiving the drawing start instruction from the user 103, the mobile terminal 101 starts the drawing function of the target application in the mobile terminal 101, and obtains the location information of the mobile terminal through the target application. When the target application in the mobile terminal 101 is switched to the background, or the mobile terminal 101 is in the screen-off state or the screen-locked state, the mobile terminal 101 draws a map image on the mobile terminal according to the location information of the mobile terminal through the central processor in the mobile terminal 101. Then, the mobile terminal 101 generates a map video stream according to the map image drawn by the central processor through the target application, and sends the map video stream to the electronic device 102 through the wireless communication module. The hardware configuration of the electronic device 102 is relatively low, and it only needs to display the corresponding map video according to the received map video stream.

[0067] Figure 4 FIG. 1 is a flowchart of a map display method provided by an embodiment of the present application. Figure 4 As shown, with the mobile terminal as the execution subject, the method of this embodiment may include the following steps:

[0068] S101 . After receiving a drawing start instruction from a user, start a drawing function of a target application in a mobile terminal, and obtain location information of the mobile terminal through the target application.

[0069] For example, the mobile terminal may be a smart terminal such as a mobile phone, a tablet computer, a smart watch, etc. The target application may be any application with a drawing function, such as various map applications.

[0070] In this step, after receiving the drawing start instruction from the user, the mobile terminal starts the drawing function of the target application. After the drawing function of the target application is started, the location information of the mobile terminal can be obtained through the target application.

[0071] The location information may include the current location of the mobile terminal, for example, a display screen of the current location, which may include roads, landmarks, etc. at the current location. The location information may also include a display screen of a target location input by a user, which may include roads, landmarks, etc. at the target location.

[0072] In some embodiments, the location information of the mobile terminal includes the current location of the mobile terminal. After starting the drawing function of the target application in the mobile terminal, the current location of the mobile terminal can be obtained through the target application. For example, the target application includes a map navigation module, and after starting the drawing function of the target application in the mobile terminal, the current location of the mobile terminal can be obtained through the map navigation module.

[0073] In some examples, after starting the drawing function of the target application in the mobile terminal, the destination information input by the user can be received through the map navigation module of the target application, for example, the destination name input by the user can be received through the map navigation module of the target application, and then the display screen of the current location of the mobile terminal and the display screen of the destination can be obtained through the target application. It should be noted that each time the mobile terminal arrives at a location, it has a corresponding current location, so the display screen of the current location of the mobile terminal can be obtained in real time through the target application, so that the navigation map image can be generated later according to the display screen of the current location and the display screen of the destination obtained in real time.

[0074] In other examples, the destination information may also be included in the drawing start instruction. For example, after receiving the destination name input by the user through the map navigation module of the target application, the drawing function of the target application in the mobile terminal is started to obtain the display screen of the current location of the mobile terminal and the display screen of the destination through the target application, so as to subsequently generate a navigation map image according to the display screen of the current location and the display screen of the destination. For example, the user can search for the destination, select the destination, and initiate navigation on the mobile terminal. The user initiating navigation is to send a drawing start instruction to the mobile terminal. After receiving the user's drawing start instruction, the mobile terminal starts the drawing function of the target application in the mobile terminal.

[0075] In other embodiments, the location information includes a display screen of the target location. For example, the drawing start instruction includes the target location. After the mobile terminal receives the drawing start instruction, the display screen of the target location is obtained through the target application, so that a map image between the target locations can be drawn later based on the display screen of the target location. For another example, after starting the drawing function of the target application in the mobile terminal, the target location input by the user can be received through the map navigation module of the target application, and the display screen of the target location is obtained through the target application, so that a map image between the target locations can be drawn later. The number of target locations can be determined according to actual conditions.

[0076] S102: When the image processor in the mobile terminal stops drawing, a central processor in the mobile terminal draws a map image on the mobile terminal according to the location information of the mobile terminal.

[0077] After the drawing function of the target application is started, a map image may be drawn on the mobile terminal by the central processor of the mobile terminal according to the location information of the mobile terminal, or by the image processor of the mobile terminal according to the location information of the mobile terminal.

[0078] It should be noted that when the target application is switched to the background, or the mobile terminal is in the screen-off or locked state, the image processor of the mobile terminal stops drawing the map image on the mobile terminal according to the location information of the mobile terminal. For example, when the target application is switched to the background or the mobile terminal is in the screen-off or locked state, the image processor of the mobile terminal stops working, and the image processor no longer renders the pages that still need to be drawn in the background, thereby stopping drawing the map image on the mobile terminal according to the location information of the mobile terminal.

[0079] Therefore, in some embodiments, when the target application is switched to background operation, or the mobile terminal is in a screen-off or locked state, the central processor in the mobile terminal draws a map image on the mobile terminal according to the location information of the mobile terminal, ensuring that the mobile terminal is in a screen-off or locked state, or the target application is switched to background operation, the mobile terminal can still generate map information, thereby enabling the electronic device to display map video in real time, thereby improving the user experience.

[0080] In other embodiments, when the image processor in the mobile terminal stops drawing due to driver problems, overheating problems, etc., the central processing unit in the mobile terminal can also draw a map image on the mobile terminal according to the location information of the mobile terminal.

[0081] For example, the location information of the mobile terminal includes the current positioning position of the mobile terminal. After obtaining the current positioning position of the mobile terminal and the destination information input by the user, the central processor in the mobile terminal can draw a navigation map image on the mobile terminal according to the current positioning position of the mobile terminal and the destination information input by the user, so that when the mobile terminal is in the screen-off or lock state, or the target application is switched to background operation, the electronic device can display the navigation video in real time, thereby improving the convenience and safety during driving.

[0082] In some examples, the target application is integrated with a software development kit corresponding to the central processing unit, and the software development kit corresponding to the central processing unit can call the central processing unit interface. When the target application is switched to background operation, or the mobile terminal is in a screen-off state or a screen-locked state, a map can be drawn on the mobile terminal according to the location information of the mobile terminal through the software development kit corresponding to the central processing unit. For example, a navigation map image is drawn on the mobile terminal according to the current location of the mobile terminal and the destination information input by the user through the software development kit corresponding to the central processing unit. Among them, the software development kit can be a software development kit (SDK) for various maps.

[0083] In some embodiments, when the image processor in the mobile terminal runs the drawing, the map image is drawn on the mobile terminal by the image processor in the mobile terminal according to the location information of the mobile terminal.

[0084] For example, when the target application is not switched to background operation, or the mobile terminal is not in a screen-off or screen-locked state, a map image can be drawn on the mobile terminal according to the location information of the mobile terminal by an image processor in the mobile terminal.

[0085] Specifically, it can detect whether the target application is switched to the background, or whether the mobile terminal is in the screen-off or lock state. If the target application is not switched to the background, or the mobile terminal is not in the screen-off or lock state, a map image is drawn on the mobile terminal according to the location information of the mobile terminal through the image processor in the mobile terminal.

[0086] For example, it is possible to detect whether the target application is included in the applications running in the background to determine whether the target application is switched to the background. It is possible to detect the brightness of the screen of the mobile terminal to determine whether the mobile terminal is in the screen-off or screen-locked state.

[0087] In other examples, the target application integrates a software development kit corresponding to the image processor, and the software development kit corresponding to the image processor can call the image processor interface. If the target application is not switched to background operation, or the mobile terminal is not in the screen-off or screen-locked state, the software development kit corresponding to the image processor draws a map image on the mobile terminal according to the location information of the mobile terminal. For example, the software development kit corresponding to the image processor draws a navigation map image on the mobile terminal according to the current location of the mobile terminal and the destination information entered by the user.

[0088] As an implementation method, the map image drawn by the image processor may contain more information than the map image drawn by the central processing unit, and / or the setting graphics contained in the map image drawn by the central processing unit are simpler than the setting images contained in the map image drawn by the image processor, thereby reducing the usage rate and power consumption of the central processing unit by simplifying the graphics (for example, simplifying route drawing) and reducing the display of non-critical information (for example, stores, place marks, etc.).

[0089] S103, generating a map video stream according to the map image drawn by the central processor through the target application, and sending the map video stream to the electronic device, so that the electronic device displays the corresponding map video after receiving the map video stream.

[0090] For example, the electronic device may be an electric two-wheeled vehicle such as an electric bicycle, an electric motorcycle, an electric scooter, or an electric three-wheeled vehicle.

[0091] In this step, a map video stream is generated by a target application according to a map image drawn by a central processor, and the map video stream is sent to an electronic device so that the electronic device can display the map video in real time.

[0092] For example, a target application generates a navigation video stream based on a navigation map image drawn by a central processor, and sends the navigation video stream to an electronic device, so that the electronic device can display the navigation video containing rich navigation data and content in real time, thereby improving the user experience.

[0093] Optionally, after the central processor draws the map image on the mobile terminal, the map image drawn by the central processor may be screen recorded or captured, and a map video stream may be generated according to the screen recording or the capture.

[0094] For example, after drawing a map image on a mobile terminal through the central processor, the map image can be displayed in the background of the mobile terminal. When the map image is displayed in the background of the mobile terminal, the map image drawn on the mobile terminal can be captured by performing background recording or screenshot of the mobile terminal, and then a map video stream can be generated according to the captured map image through the target application.

[0095] It should be noted that, when the image processor in the mobile terminal runs the drawing, the map image can be drawn on the mobile terminal by the image processor according to the location information of the mobile terminal. Accordingly, the map video stream can be generated by the target application according to the map image drawn by the image processor, and the map video stream can be sent to the electronic device so that the electronic device displays the map video stream generated according to the map image drawn by the image processor, so that the electronic device can display the map video.

[0096] For example, after a map image is drawn on a mobile terminal by an image processor, a screen recording or screenshot is performed on the map image drawn by the image processor, and a map video stream is generated according to the screen recording or screenshot.

[0097] For example, after drawing a map image on a mobile terminal through an image processor, the map image can be displayed in the background of the mobile terminal. When the map image is displayed in the background of the mobile terminal, the map image drawn on the mobile terminal can be captured by performing background recording or screenshot of the mobile terminal, and then a map video stream can be generated according to the captured map image through the target application.

[0098] For another example, after drawing a map image on a mobile terminal through an image processor, the map image can be displayed on the screen of the mobile terminal. When the map image is displayed on the screen of the mobile terminal, the map image drawn on the mobile terminal can be captured by recording or taking a screenshot of the screen of the mobile terminal, and then a map video stream can be generated according to the captured map image through the target application.

[0099] In some embodiments, after the map video stream is generated, the map video stream can be encoded according to the audio and video codec parameters of the electronic device and sent to the electronic device, so that the electronic device decodes the received map video stream and displays the corresponding map video. The audio and video codec parameters can include, for example, the frame rate and bit rate supported by the electronic device.

[0100] In some examples, the mobile terminal can transmit the map video stream to the electronic device via wireless communication. For example, a wireless communication connection is established between the mobile terminal and the electronic device, and the wireless communication connection may include a direct or indirect wireless communication connection, and specifically may include a Bluetooth communication connection and / or a Wifi communication connection, etc. For another example, the mobile terminal can transmit the video stream to the electronic device after transfer. After the mobile terminal generates the map video stream, the map video stream is sent to the electronic device via a wireless communication connection. In some embodiments, when the electronic device displays a map video, the mobile terminal may send an end display instruction to the electronic device so that the electronic device stops displaying the map video; and / or, after receiving the end display instruction sent by the electronic device, the mobile terminal stops sending the map video stream to the electronic device so that the electronic device stops displaying the map video.

[0101] The map display method provided by the present application uses the central processing unit in the mobile terminal to draw the map image when the image processor in the mobile terminal stops drawing, thereby solving the problem that the image processor cannot draw the map image when the target application is switched to the background or the mobile terminal is in the screen-off or screen-locked state, so that the electronic device can continue to display the map. In addition, the electronic device only needs to display the corresponding map video according to the received map video stream, which has low hardware requirements for the electronic device, so that the electronic device can display the map in a low hardware environment.

[0102] Figure 5 FIG. 1 is a flowchart of a map display method provided by an embodiment of the present application. Figure 5 As shown, with the electronic device as the execution subject, the method of this embodiment may include the following steps:

[0103] S201. Receive a first map video stream sent by a mobile terminal.

[0104] Among them, the first map video stream is generated by the target application in the mobile terminal starting the drawing function of the target application in the mobile terminal after receiving the user's drawing start instruction, obtaining the location information of the mobile terminal through the target application, and drawing the map image on the mobile terminal according to the location information of the mobile terminal through the central processing unit of the mobile terminal when the image processor in the mobile terminal stops drawing, and the target application is generated according to the map image drawn by the central processing unit.

[0105] For example, the situation where the image processor in the mobile terminal stops drawing includes: the target application is switched to background operation, or the mobile terminal is in the screen-off or screen-locked state.

[0106] S202. Display the map video corresponding to the first map video stream.

[0107] In some embodiments, the electronic device receives a first map video stream sent by a mobile terminal and encoded according to audio and video codec parameters of the electronic device, and may first encode the received first map video stream and then display a map video corresponding to the first map video stream.

[0108] In some embodiments, the electronic device stops displaying the map video after receiving an end display instruction sent by the mobile terminal or receiving a trigger operation from the user.

[0109] In some embodiments, the electronic device may also receive a second map video stream sent by the mobile terminal, and display a map video corresponding to the second map video stream. The second map video stream is generated by the target application according to the map image drawn by the image processor when the image processor in the mobile terminal runs the drawing, and the map image is drawn on the mobile terminal by the image processor in the mobile terminal according to the location information of the mobile terminal.

[0110] For example, the situation where the image processor in the mobile terminal stops drawing includes: the target application is not switched to background operation, or the mobile terminal is not in the screen-off or screen-locked state.

[0111] The map display method provided in this embodiment is that after receiving the first map video stream sent by the mobile terminal, the electronic device displays the corresponding map video, which has low hardware requirements for the electronic device, so that the electronic device can display the map in a low hardware environment.
