Detailed Description

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

In the technical scheme of the disclosure, the related processes of collecting, storing, using, processing, transmitting, providing, disclosing and the like of the personal information of the user accord with the regulations of related laws and regulations, and the public order colloquial is not violated.

In this case, if the user wants to display multimedia information of different mobile phones on different display screens, a set of special vehicle system and connection module (such as WIFI module, bluetooth module, etc.) needs to be configured for each display screen, which increases the cost of vehicle manufacture.

In order to solve the above-mentioned problems, an embodiment of the present disclosure provides a screen projection method for projecting multimedia information of different terminals on different display screens. The screen projection method is applied to the vehicle-mounted electronic equipment deployed on the vehicle. The vehicle may include a plurality of display screens, and a plurality of connection management Applications (APP) corresponding to the plurality of display screens one to one may be installed on the in-vehicle electronic device. The screen projection method can be executed by a vehicle-mounted system in the vehicle-mounted electronic equipment, and also can be executed by a processor, a functional module, a chip or a system on a chip in the vehicle-mounted electronic equipment, and the embodiment of the disclosure is not limited to be executed. For convenience of description, the following description will take an in-vehicle electronic apparatus as an example.

In the screen projection method, after receiving terminal information from a plurality of terminals, for each display screen in the plurality of display screens, the vehicle-mounted electronic equipment can control the display screen to display a connection management page corresponding to the connection management APP according to the terminal information of the plurality of terminals. Wherein the connection management page may include terminal information of a plurality of terminals. Then, the vehicle-mounted electronic device can respond to the operation of the user on the connection management page of the first display screen for selecting the terminal information of the first terminal, and establish the screen throwing relation between the first terminal and the first display screen. Wherein the plurality of display screens includes a first display screen.

As can be seen from the above, for a vehicle configured with multiple display screens, the embodiment of the disclosure does not need to configure a dedicated vehicle-to-machine system and a connection module for each display screen, and can realize that multimedia information of different terminals is displayed on different display screens through one vehicle-to-machine system, thereby reducing the vehicle manufacturing cost.

The screen projection method provided by the embodiment of the disclosure can be applied to a screen projection system. Fig. 1 shows a schematic diagram of a composition of a screen projection system according to an embodiment of the present disclosure. As shown in fig. 1, the screen projection system may include: an in-vehicle electronic device 102 disposed on a vehicle 101, a plurality of display screens (fig. 1 is illustrated by way of example with 3 display screens: display screen 103-1, display screen 103-2, and display screen 103-3), and a plurality of terminals (fig. 1 is illustrated by way of example with 3 terminals: terminal 104-1, terminal 104-2, and terminal 104-3). The in-vehicle electronic device 102 is communicatively coupled to each of the plurality of display screens.

Alternatively, the multiple display screens of the vehicle 101 may be deployed at any location within the vehicle 101.

For example, as shown in FIG. 1, the display screen 103-1 may be deployed on a center console for use by a user of a primary or secondary drive. The display screen 103-2 may be disposed at the rear of the headrest of the primary driving seat, and the display screen 103-3 may be disposed at the rear of the headrest of the secondary driving seat. Display 103-2 and display 103-3 may be available to users of the back row.

It should be appreciated that the in-vehicle electronic device 102 typically includes a display screen for interacting with a user. In this case, the display screen of the in-vehicle electronic device 102 and any one of the plurality of display screens may be the same display screen, that is, the in-vehicle electronic device 102 and any one of the plurality of display screens may be integrated together, for example, the in-vehicle electronic device 102 and the display screen 103-1 of the center console may be integrated together.

The in-vehicle electronic device 102 has an in-vehicle system disposed thereon. And a plurality of connection management APP corresponding to the display screens one by one are installed in the vehicle-mounted system. Each display screen may display an APP interface of the connection management APP corresponding thereto, for example, a connection management page of the connection management APP in the embodiment of the present application.

The plurality of connection management APPs may be a plurality of software packages installed in the vehicle system by an engineer at the time of shipment of the vehicle. Each software package has the same function, but the names of the software packages are different. The in-vehicle electronic device 102 may control different connection management APPs to be displayed on different display screens.

Alternatively, the vehicle system may be an operating system such as an android system, which is not limited in this embodiment.

Illustratively, it is assumed that the plurality of connection management APPs includes a first APP, a second APP, and a third APP. The in-vehicle electronic device 102 can control: display screen 103-1 displays the APP interface of the first APP, display screen 103-2 displays the APP interface of the second APP, and display screen 103-3 displays the APP interface of the third APP.

Optionally, the connection management APP may be a hundred degree internet of vehicles (carlife) APP, may also be an apple vehicle system (carrlay) APP, and may also be other internet of vehicles APP, which is not limited in this disclosure.

The vehicle-mounted electronic device 102 has a screen projection function, and the screen projection function is executed to realize the screen projection display of the multimedia content of the terminal on the display screen.

For example, as shown in fig. 1, the in-vehicle electronic device 102 may implement: the multimedia information of the terminal 104-1 is displayed on the display screen 103-1, the multimedia information of the terminal 104-2 is displayed on the display screen 103-2, and the multimedia information of the terminal 104-3 is displayed on the display screen 103-3.

It should be noted that, the in-vehicle electronic device 102 and each terminal include a plurality of communication modules, such as a bluetooth module, a wireless network communication technology (wireless fidelity, WIFI) module, and the like, for implementing information interaction between the in-vehicle electronic device 102 and the plurality of terminals.

Alternatively, the terminal may be a device that provides voice and/or data connectivity to the user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem.

The wireless terminals may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers with mobile terminals, as well as portable, pocket, hand-held, computer-built-in or car-mounted mobile devices which exchange voice and/or data with radio access networks, e.g. cell phones, tablet computers, notebook computers, netbooks, personal digital assistants (personal digital assistant, PDA).

The following describes in detail the technical solutions provided by the embodiments of the present disclosure with reference to the accompanying drawings.

Fig. 2 illustrates a screen projection method provided by an embodiment of the present disclosure, where the screen projection method may be applied to the vehicle-mounted electronic device 102 in fig. 1. As shown in fig. 2, the screen projection method specifically includes:

s201, the vehicle-mounted electronic equipment receives terminal information from a plurality of terminals.

The vehicle-mounted electronic device is the vehicle-mounted electronic device 102 in fig. 1, the plurality of terminals are the plurality of terminals in fig. 1, and related functions of the vehicle-mounted electronic device may be described in reference to the corresponding embodiment of the vehicle-mounted electronic device 102 in fig. 1, which is not described herein. Accordingly, the related functions of the plurality of terminals may be described with reference to fig. 1 in the corresponding embodiments of the plurality of terminals, which are not described herein.

Specifically, after each terminal and the vehicle-mounted electronic device establish communication connection, each terminal and the vehicle-mounted electronic device may be located under the same local area network. In this case, each terminal may transmit its own terminal information to the in-vehicle electronic device based on the above-described local area network.

Alternatively, the terminal information may include a protocol (Internet Protocol, IP) address of an interconnection between networks of the terminal, a port number of the terminal, a model number of the terminal, a brand of the terminal, a media access control address (Media Access Control Address, MAC) address of the terminal, and the like.

S202, for each display screen in the plurality of display screens, the vehicle-mounted electronic equipment controls the display screen to display a connection management page of a corresponding connection management APP according to terminal information of the plurality of terminals.

Wherein the connection management page includes terminal information of a plurality of terminals.

Specifically, after terminal information of a plurality of terminals is acquired, in order to facilitate a user to manage the terminal information of the plurality of terminals through display screens, each display screen can display a connection management page of a connection management APP corresponding to the display screen. In the connection management page, terminal information of a plurality of terminals may be included.

By way of example, fig. 3 shows a schematic diagram of a connection management page displayed by a display screen. As shown in fig. 3, the connection management page may include three display areas: a display area 301 of a connected terminal, a display area 302 of a connectable terminal, and a display area 303 of a saved terminal.

The display area 301 of the connected terminal is used to display terminal information of the terminal that establishes a screen-casting relationship with the display screen. Fig. 3 illustrates an example of terminal information as a terminal name, for example, the terminal 1 in fig. 3.

Optionally, a disconnect control corresponding to each connected terminal may also be displayed in the display area 301 of the connected terminal, for example, in fig. 3, disconnect control 304 corresponding to terminal 1. The disconnection control 304 is used for disconnecting the screen-throwing relationship of the terminal 1 and the display screen in response to a triggering operation performed on the disconnection control 304.

When the display screen does not establish a screen-throwing relationship with any terminal, the terminal information of any terminal is not displayed in the display area 301 of the connected terminal.

The display area 302 of the connectable terminal is used to display terminal information of a terminal with which a screen-casting relationship can be established but which has not yet been established. Fig. 3 illustrates an example of terminal information as a terminal name, for example, the terminal 2 and the terminal 3 in fig. 3.

Optionally, when the display is a main display (for example, a display disposed on a central console), if a certain terminal has established a screen-throwing relationship with other displays, the display area 302 of the connected terminal may also display information of the connected associated display of the terminal, for example, the connected rear left display 305 of the terminal 3 in fig. 3.

In this case, the display area 302 of the connected terminal may also display a disconnect control for the terminal, such as disconnect control 306 of terminal 3 in fig. 3. The disconnection control 306 is used for disconnecting the screen-throwing relationship of the terminal 3 with other display screens in response to a triggering operation performed on the disconnection control 306.

The display area 303 of the saved terminal is used for displaying terminal information of the terminal which establishes the screen-throwing relation with the display screen in the historical time period but does not establish the screen-throwing relation at the current moment. Fig. 3 illustrates an example of terminal information as a terminal name, for example, the terminal 4 in fig. 3.

Optionally, the display area 303 of the saved terminal may also display a deletion control of the terminal, for example, the deletion control 307 of the terminal 4 in fig. 3. The deletion control 307 is configured to delete a history of the screen-over relationship established between the terminal 4 and the display screen in response to a triggering operation performed on the deletion control 307.

S203, the vehicle-mounted electronic equipment responds to the operation of the user on the connection management page of the first display screen for selecting the terminal information of the first terminal, and establishes the screen throwing relation between the first terminal and the first display screen.

Wherein the plurality of display screens includes a first display screen; the first terminal is any one of a plurality of terminals; the first display screen is any one of a plurality of display screens; the screen-throwing relation between the first terminal and the first display screen is used for representing that the multimedia information of the first terminal is displayed on the first display screen in a screen-throwing mode.

Optionally, the multimedia information displayed by the screen may be a video played by the terminal, a terminal storage address book, an APP installed by the terminal, and the like.

Specifically, since the connection management page of the connection management APP displayed on each display screen includes terminal information of a plurality of terminals, different users can select terminals that want to establish a screen-throwing relationship on different display screens. When the user performs the terminal information operation for selecting the first terminal on the connection management page of the first display screen, the vehicle-mounted electronic device can respond to the operation of the user to establish the screen throwing relation between the first terminal and the first display screen. Thus, the first display screen can throw screen to display the multimedia information of the first terminal.

Based on the screen projection method shown in fig. 2, for a vehicle configured with a plurality of display screens, the embodiment of the disclosure can realize screen projection display of multimedia information of different terminals on different display screens through one vehicle system without configuring a special vehicle system and a connecting module for each display screen, thereby reducing the vehicle manufacturing cost.

Fig. 4 illustrates yet another screen projection method provided by an embodiment of the present disclosure, which may also be applied to the in-vehicle electronic device 102 in fig. 1. As shown in fig. 4, the screen projection method specifically includes:

s401, the vehicle-mounted electronic equipment determines a main connection management APP and an auxiliary connection management APP in a plurality of connection management APP.

Specifically, in order to realize communication among a plurality of connection management APPs, in the process of initializing a vehicle-mounted system, the vehicle-mounted electronic device can mutually bind the control of the plurality of connection management APPs based on a cross-process communication mode of an android system. Therefore, terminal information of a plurality of terminals, whether a display screen corresponding to each connection management APP has established a screen throwing relation with the terminal or not and other information can be interacted among the plurality of connection management APPs.

Alternatively, the initialization process of the vehicle-mounted system may be an initialization process when the vehicle-mounted system is started each time, or may be an initialization process when the vehicle leaves the factory, which is not limited in the embodiment of the present disclosure.

After the connection management APP is mutually bound, the vehicle-mounted electronic equipment can determine any one connection management APP of the connection management APP as a main connection management APP, and other connection management APP are determined as auxiliary connection management APP.

In this way, when information interaction is performed with another module or device (for example, a communication module or a terminal of a vehicle), only the master connection management APP of the plurality of connection management APPs may perform information interaction with another module or device. After the main connection management APP obtains information, the obtained information can be sent to the auxiliary connection management APP, and each connection management APP does not need to interact with other modules or devices, so that the efficiency of information interaction is improved.

S402, the vehicle-mounted electronic equipment responds to a broadcast instruction of the main connection management APP and sends a first broadcast message.

Wherein the first broadcast message includes an identification of the vehicle-mounted electronic device.

Optionally, the broadcast instruction may be generated by the active connection management APP in response to a broadcast operation performed by the user on a display screen corresponding to the active connection management APP, or may be generated periodically and automatically (e.g., after the vehicle-mounted electronic device is started, the broadcast instruction is sent to the vehicle-mounted electronic device every 1 minute), which is not limited in this embodiment of the disclosure.

According to the method, when the first broadcast message is required to be sent, only the main connection management APP is required to send the broadcast instruction to the vehicle-mounted electronic equipment, and each connection management APP is not required to send the broadcast instruction to the vehicle-mounted electronic equipment, so that data interaction is reduced, and data processing pressure of the vehicle-mounted electronic equipment is reduced.

After receiving the broadcast instruction, the vehicle-mounted electronic device may send a first broadcast message through a first communication module of the vehicle within a signal coverage range of the first communication module in response to the received broadcast instruction.

Optionally, the first communication module of the vehicle may be a bluetooth module of the vehicle, the first broadcast message may be a bluetooth low energy (Bluetooth Low Energy, BLE) broadcast message, and the vehicle identifier may be a device Name (Deivce Name) of WIFI P2P (WIFI Peer-to-Peer) of the vehicle system. The first communication module may also be another communication module, such as a WiFi module, which is not limited herein.

S403, the vehicle-mounted electronic equipment receives connection requests sent by the plurality of terminals according to the identifications of the vehicle-mounted electronic equipment, and communication connection with the plurality of terminals is established.

Specifically, after the vehicle-mounted electronic device sends the first broadcast message, a plurality of terminals in the signal coverage range of the first communication module of the vehicle can receive the first broadcast message through the first communication module of the terminal.

Then, for each of the plurality of terminals, a connection instruction may be initiated to the connection management APP installed in the terminal. After receiving the connection instruction, the connection management APP installed on the terminal can display the vehicle-mounted identification of the vehicle-mounted electronic equipment on a display screen of the terminal. The user can execute the selected operation on the car machine identification on the display screen of the terminal. Correspondingly, the terminal can respond to the selected operation executed by the user and establish communication connection with the vehicle-mounted electronic equipment through the second communication module of the terminal, the vehicle machine identifier and the second communication module of the vehicle.

After the communication connection between the terminal and the vehicle-mounted electronic equipment is established successfully, the terminal and the vehicle-mounted electronic equipment are located under the same local area network.

Optionally, the first communication module of the terminal may be a bluetooth module of the terminal, the second communication module of the terminal may be a WIFI module of the terminal, the second communication module of the vehicle may be a WIFI module of the vehicle, and the communication connection between the terminal and the vehicle-mounted electronic device may be a WIFI P2P communication connection.

Further, after establishing communication connection with the plurality of terminals, the vehicle-mounted electronic device receives terminal information from the plurality of terminals, and specifically includes:

S404, for each of the plurality of terminals, the in-vehicle electronic device receives the second broadcast message transmitted by the terminal based on the communication connection.

Wherein the second broadcast message includes terminal information of the terminal.

Specifically, after each terminal and the vehicle-mounted electronic device establish communication connection, each terminal and the vehicle-mounted electronic device may be located under the same local area network. In this case, each terminal may transmit its corresponding second broadcast message based on the communication connection.

Alternatively, the second broadcast message may be a user datagram protocol (User Datagram Protocol, UDP) broadcast message. A plurality of terminals and vehicle-mounted electronic devices under the unified local area network can agree on a port number. When a plurality of terminals send a plurality of UDP broadcast messages, the vehicle-mounted electronic equipment can monitor the agreed port numbers to acquire a plurality of UDP broadcast messages.

Since each UDP broadcast message carries terminal information of the terminal, the vehicle-mounted electronic device may extract terminal information of a plurality of terminals from a plurality of UDP broadcast messages.

Further, after receiving terminal information from a plurality of terminals, for each display screen in the plurality of display screens, the vehicle-mounted electronic device controls the display screen to display a connection management page of a corresponding connection management APP according to the terminal information of the plurality of terminals, and specifically includes:

The vehicle-mounted electronic equipment transmits terminal information of the plurality of terminals to each of the plurality of connection management APP. Therefore, each connection management APP can display the connection management page of the connection management APP on the corresponding display screen, so that a user can select a proper terminal to establish a screen throwing relation with the display screen.

In one implementation manner, the vehicle-mounted electronic device transmits terminal information of a plurality of terminals to each of a plurality of connection management APPs, and specifically includes:

s405, the vehicle-mounted electronic equipment transmits terminal information of a plurality of terminals to the main connection management APP, and the main connection management APP transmits the terminal information of the plurality of terminals to the auxiliary connection management APP.

It should be appreciated that a vehicle system deployed on an in-vehicle electronic device may include a control layer and an application layer. The control layer may be a system level other than an application layer in the vehicle system. The control layer and the application layer may interact data. The application layer may comprise a plurality of connection management APPs as described above. The control layer is used for controlling each connection management APP of the application layer to display a connection management page in charge of data receiving and transmitting. The connection management APPs can communicate based on a cross-process communication mode of the android system.

The control layer can acquire terminal information of a plurality of terminals through a communication module of the vehicle-mounted electronic equipment, and send the terminal information of the plurality of terminals to the application layer. After acquiring the terminal information of the plurality of terminals, the application layer can transmit the terminal information of the plurality of terminals to the main connection management APP. After receiving the terminal information of the plurality of terminals, the main connection management APP can transmit the terminal information of the plurality of terminals to the auxiliary connection management APP based on a cross-process communication mode of the android system.

From the above, when each connection management APP needs to obtain terminal information of a plurality of terminals, the embodiment of the disclosure only needs the master connection management APP to obtain the terminal information of the plurality of terminals through the control layer. After the main connection management APP obtains the terminal information of the plurality of terminals, the obtained terminal information of the plurality of terminals can be sent to the auxiliary connection management APP based on the inter-process communication mode of the vehicle-mounted system, each connection management APP does not need to obtain the terminal information of the plurality of terminals through a control layer, the interaction times of data are reduced, and the data processing pressure of the vehicle-mounted electronic equipment is reduced.

S406, the vehicle-mounted electronic equipment receives indication information from each connection management APP.

The indication information is used for indicating and displaying the connection management page.

Specifically, after acquiring terminal information of a plurality of terminals, each connection management APP of the application layer may send, to the control layer, indication information for indicating to display a connection management page, so that the connection management page of the corresponding connection management APP is displayed on the display screen later.

S407, the vehicle-mounted electronic equipment controls a display screen corresponding to the connection management APP to display a connection management page according to the indication information of each connection management APP.

Specifically, after receiving the indication information of each connection management APP, the control layer may control the display screen to display the connection management page of the corresponding connection management APP, so that the user may select a suitable terminal to establish a screen-throwing relationship with the display screen.

S408, the vehicle-mounted electronic equipment responds to the operation of the user on the connection management page of the first display screen for selecting the terminal information of the first terminal, and establishes the screen throwing relation between the first terminal and the first display screen.

Wherein the plurality of display screens includes the first display screen.

It should be noted that the specific implementation of step S408 is the same as that of step S203, and will not be described again.

S409, the vehicle-mounted electronic equipment controls the display screens except the first display screen to update and display the connection management page of the corresponding connection management APP.

Wherein the updated connection management page comprises: terminal information of other terminals than the first terminal among the plurality of terminals, and/or information for indicating an associated display screen of the first terminal.

Specifically, in order to remind the user that the first terminal and the first display screen have established a screen-throwing relationship, the vehicle-mounted electronic device may control other display screens to update the displayed terminal connection management page. The updated terminal connection management page may not display the terminal information of the first terminal, or may display the information of the associated display screen of the first terminal. Therefore, the user can be prevented from executing the association operation on one terminal on a plurality of display screens, and the overall use experience of the plurality of display screens in the vehicle is improved.

Optionally, in the case that the vehicle-mounted electronic device comprises a control layer and an application layer, the specific implementation manner of the vehicle-mounted electronic device for controlling other display screens to update the connection management page displayed is as follows:

after the first terminal and the first display screen establish a screen throwing relation, the connection management APP corresponding to the first display screen can send a prompt message to the connection management APP corresponding to other display screens, and the prompt message is used for prompting the first terminal and the first display screen to establish the screen throwing relation.

After receiving the prompt message, the connection management APP corresponding to the display screen can update the displayed connection management page and send an update instruction to the control layer. After receiving the update instruction, the control layer can control other display screens to update the displayed connection management page.

The above description has been made mainly from the point of view of the in-vehicle electronic device. It will be appreciated that, in order to implement the above-mentioned functions, the vehicle-mounted electronic device includes software modules that perform respective functions, such as a primary connection management APP, a secondary connection management APP, and the like. Embodiments of the present application are described below from the perspective of software modules. Fig. 5 illustrates yet another screen projection method provided by an embodiment of the present disclosure. In fig. 5, the screen projection method is illustrated by taking an example that a plurality of connection management APPs include a primary connection management APP and a secondary connection management APP, and a plurality of terminals include a first terminal and a second terminal, and specifically includes:

s501, in the process of initializing a vehicle system, binding a main connection management APP and an auxiliary connection management APP.

S502, a Bluetooth module of the vehicle is controlled by the main connection management APP to send BLE broadcast messages.

Specifically, the master connection management APP may send a broadcast instruction to a processing core of a control layer of the vehicle machine system, where the processing core of the control layer responds to the broadcast instruction, and controls, through a driving core of a bluetooth module of the vehicle, the bluetooth module of the vehicle to send a BLE broadcast message.

S503, the first terminal and the second terminal respond to the received BLE broadcast message to establish communication connection with the vehicle-mounted system.

S504, the first terminal sends UDP broadcast messages of the first terminal to the main connection management APP.

Wherein the UDP broadcast message for the first terminal includes terminal information for the first terminal.

Specifically, the first terminal may send, through the WIFI module of the first terminal, a UDP broadcast message carrying terminal information of the first terminal to the WIFI module of the vehicle. After receiving the UDP broadcast message, the WIFI module of the vehicle can send the UDP broadcast message to the processing core of the control layer through the driving core of the WIFI module. The processing core of the control layer can extract the terminal information of the first terminal in the UDP broadcast message and send the terminal information of the first terminal to the main connection management APP.
