FIG. 4 shows a flow diagram of a screen projection method in one embodiment.

Referring to fig. 4, taking the application of the screen projection method to the system in fig. 1 and the electronic device shown in fig. 2 as an example, the screen projection method may include the following steps:

and S42, receiving original information sent by the vehicle machine.

The connection between the electronic device 200 and the vehicle 300 may be established in various wireless or wired manners, such as bluetooth, Wifi, HDMI, USB, etc., so as to implement the functions of communication connection, data transmission, audio and video synchronization, etc., between the electronic device 200 and the vehicle 300.

The original information may include speed information, position information, rainfall information, ambient light information, visibility information, road information, and the like, and may be one of the information or a combination of more than one of the information.

The speed information may be used to indicate the speed at which the vehicle is traveling. The vehicle may have a variety of methods to obtain speed information. For example, the speed information may be obtained by a speed sensor, or the vehicle position change and the corresponding time may be obtained by a GPS positioning system, or the vehicle position change and the corresponding time may be obtained by a vehicle-mounted device connected to a network and then by data of an application such as a map navigation application.

The location information may be used to indicate where the vehicle is located. The vehicle machine can acquire the position of the vehicle through a GPS positioning system.

The rainfall information may be used to indicate the magnitude of the rainfall, and thus the real-time weather conditions. The vehicle can acquire rainfall information through the rainfall sensor, and can also acquire weather information after being connected with a network through a vehicle machine.

The ambient light information may be used to indicate light brightness information of the vehicle surroundings. The vehicle may acquire ambient light information through an ambient light sensor.

The visibility information may be used to indicate the visibility of the area in which the vehicle is located. The vehicle can obtain the visibility information through the combination of one or more information such as ambient light information and rainfall information, and can also obtain the visibility information of the area where the vehicle is located after the vehicle is connected with a network through a vehicle machine.

The road information may be used to indicate congestion conditions, accident conditions, traffic control conditions, etc. for the road. The vehicle can obtain real-time road information after being connected with a network through a vehicle machine.

In another embodiment, the raw information may be obtained by the electronic device 200. The electronic equipment can acquire various original information in a mode of acquiring real-time road information through a GPS positioning function and a connection network.

And S44, processing the original information to obtain safety state information.

After receiving one or more kinds of original information sent by the car machine, the electronic device 200 may process the original information to obtain the security status information.

The safety state information may be information indicating a driving safety state of the vehicle, the driving safety state of the vehicle may include a high speed driving state, a normal driving state, a congestion state, a red light state, a parking state, a heavy rain weather state, a snow day state, and the like, and the safety state information may be processed from the original information.

In one embodiment, the high speed running state may be preset to a state when the running speed of the vehicle is greater than a certain speed threshold. For example, a running state in which the vehicle running speed >60km/h may be preset as a high speed running state. Further, the running state may be determined in conjunction with the position information of the vehicle. For example, the position information where the vehicle is traveling on a highway may be one of the conditions for determining the high-speed traveling state of the vehicle.

In one embodiment, the normal running state may be preset to a state when the running speed of the vehicle is in a certain speed threshold interval. For example, a running state of 5km/h ≦ vehicle running speed ≦ 60km/h may be preset as the normal running state. Further, the driving state of the vehicle can be determined in combination with the position information of the vehicle. For example, the position information of the vehicle traveling on the road with the speed limit of 60km/h may be one of the conditions for determining the normal traveling state of the vehicle.

In one embodiment, the congestion state may be preset to a state when the traveling speed of the vehicle is lower than a certain speed threshold interval. For example, a running state in which the vehicle running speed is <5km/h may be preset as the congestion state. In addition, the driving state of the vehicle can be judged by combining the road condition information. For example, when the link on which the vehicle travels is a congested link, the travel state of the vehicle may be determined as a congested state.

In one embodiment, the red light waiting state may be preset as a state in which the vehicle is waiting for parking at a traffic light intersection. Whether the vehicle is in the red light waiting state or not can be judged through vehicle running information such as position information, real-time road condition information and running speed of the vehicle.

In one embodiment, the parking state may be preset to a state where the vehicle is parked for longer than a certain time threshold. For example, a state in which the parking time is longer than 2 minutes may be preset as the parking state. Further, the parking state can be distinguished from other vehicle states such as a traffic jam state, a red light state, and the like, by the position information of the vehicle, the road condition information, and the like.

And S46, determining the application displayed on the vehicle machine in a preset application list according to the safety state information. The preset application list may be a list formed by various applications (i.e., APPs) that can be displayed on the car machine 300 on the electronic device 200.

In one embodiment, the preset application list may be set by a user. The user may add an application, which the user wishes to display on the in-vehicle machine 300, to the application list on the electronic device 200. Applications added to the application list will be available for display on the in-vehicle machine 300 according to the security status information. For example, a user may want to display a plurality of applications, such as a music application, a navigation application, an instant messenger application, etc., through the in-vehicle machine 300 while using a vehicle, and at this time, the user may add the applications to a list in advance without having to open the plurality of applications one by one before each use of the vehicle or manually switch the applications while using the vehicle. The preset application list is set by the user, so that the user can determine which applications are projected to be displayed on the car machine 300 according to personal preference, use habits and the like, and the screen projection of the car machine 300 is more in line with the use requirements of the user.

In another embodiment, the preset application list may be automatically generated according to a user's habit of using the application. For example, the electronic device 200 may select an application with the highest frequency of use or the longest time of use by the user to be placed in the application list, and may dynamically adjust the application list according to the change of the user's usage habits on a regular basis or in real time, so that the application list can better reflect the interests and habits of the user. For another example, the electronic device 200 may obtain habits of the user in using the application in different time periods, so as to update the application list in different time periods, so that the applications on the application list are more suitable for the use habits and interests of the user, and a better use experience is provided for the user.

In another embodiment, the preset application list may be a default application list. The default application list may be composed according to applications that most users are interested in, applications that are downloaded most frequently, applications that are most closely related to driving scenes, and the like. The default application may be dynamically adjusted in real-time or periodically. The default application list can also be edited by the user, and the user can add, delete and adjust the priority of the applications in the default application list according to the preference and the use habit of the user. The default application list is preset, so that a more convenient application screen projection function can be provided for a user, and meanwhile, the user is allowed to edit the default application list, so that the individuation of the default application list can be considered.

The application displayed on the in-vehicle device is determined in the preset application list according to the safety state information, which may be that the electronic device 200 determines the application displayed on the in-vehicle device according to the safety state information and the corresponding relationship between the safety state information and the application in the preset application list.

In one embodiment, the correspondence between the security status information and the applications in the preset application list may be set by a user. The user can set the corresponding relation according to own use habits, hobbies, requirements and the like. One type of security state information may correspond to one or more applications, or one type of security state information may not correspond to any application.

For example, the user may preset the application corresponding to the high-speed driving state as a map application; setting applications corresponding to the normal driving state as map applications, music applications, book listening applications and the like; setting applications corresponding to the congestion state into instant chat applications, short message applications and the like; setting applications corresponding to the red light waiting states into instant chat applications, short video applications and the like; and setting the application corresponding to the parking state into a short video application, a web browsing application, a reading application and the like. The corresponding relation between the application interface display condition and the application interface is only exemplified, and the user can preset and change the corresponding relation between the application interface display condition and the application interface at any time according to own preference and use habit so as to obtain better driving experience.

In another embodiment, the user may preset only the application programs that the user wishes to pay attention to during use of the vehicle, and the correspondence between the safety status information and the application is intelligently determined by the electronic device 200. For example, the user may set an instant chat application, a short video application, or a news browsing application as the application that the user wishes to pay attention to during the use of the vehicle, and the electronic device 200 may intelligently establish a corresponding relationship between the security status information and the application that the user wishes to pay attention to. For example, when the vehicle is in the red waiting light state, the electronic device 200 determines that the instant chat type application and the short video application are displayed on the car machine 300; when the vehicle is in a parking state, the electronic device 200 determines to display a chat-type application, a short video-type application, and a news-browsing-type application at the in-vehicle machine 300. Because the user only needs to set the application which the user wants to pay attention to, and does not need to set the specific corresponding relation between the safety state information and the application, the operation is simplified, and more intelligent application screen projection experience is obtained.

In another embodiment, the correspondence between the security state information and the application may be configured to facilitate secure use of the application program in the in-vehicle environment. In consideration of the driving safety of the vehicle, the correspondence relationship between some safety states and the application may be configured as a relationship that is not allowed to be set, or the correspondence relationship between some safety state information and the application may be configured as a mandatory correspondence relationship. For example, the user may not be allowed to preset a corresponding relationship between the high-speed driving state and applications such as an instant chat application, a short video application, a web browsing application and the like, so as to prevent the driving safety from being affected by the use of the software on the vehicle machine by the user in the driving process of the vehicle. For example, in a heavy rain state or a snow state, the correspondence between the normal driving state, the congestion state, and the like and the applications such as the instant chat application, the short video application, and the like may be cut off to ensure the driving safety.

And S48, sending the applied multimedia information to the vehicle machine for displaying application by the vehicle machine.

After determining the application to be displayed on the car machine 300 in the preset application list according to the corresponding relationship between the security status information and the application, the electronic device 200 may encode the multimedia information of the application and send the encoded multimedia information to the car machine 300, so that the car machine 300 can display the application.

In one embodiment, after determining the application to be displayed in the in-vehicle device 300, the electronic device 200 switches the application from the system screen to the virtual screen and encodes the application data. It is understood that the encoding technique is known per se to those skilled in the art, such as encoding video with h.264/265, encoding pictures with JPG, etc., and encoding audio with AAC/MP3, etc., which are not described herein. After the user data is encoded, the encoded data is transmitted to the car machine 300 in a wireless or wired manner, and after the car machine 300 receives the encoded data, the application is displayed according to the encoded data. It is understood that the multimedia information may be at least one of image information, audio information, video information, or a combination thereof. For example, when the application of screen projection is a music application, the transmitted multimedia information may be audio information of music, or image information of covers such as songs and albums, audio information of music, or video information of music videos. The type of multimedia information may vary depending on the specific type or function of the application and is not limited herein.

In another embodiment, for an application that is not already started on the electronic device 200, the electronic device 200 may start the application and leave the application running in the background.

In yet another embodiment, after the electronic device 200 terminates the screen-casting to the car machine 300, the car machine 300 may resume displaying its own application. For example, the in-vehicle device 300 may resume its own map-like application display when the vehicle changes from the red waiting state to the normal driving state. Therefore, the intelligent alternate use of the electronic device 200 application program and the car machine 300 application program can be realized, the power consumption of the electronic device is saved, and the car machine 300 is more flexible to use and better in user experience.

In summary, according to the screen-casting method of the exemplary embodiment of the present disclosure, according to the driving information of the vehicle and the application program that the user wants to focus on during the use of the vehicle, the corresponding application is automatically selected to be displayed on the vehicle controller 300 based on the driving state of the vehicle. Therefore, the method is beneficial to a user not to control the electronic equipment 200 in the vehicle using process, and the interested application interface can be conveniently obtained at the display end of the vehicle machine 300, so that the efficiency of using related application programs by the user is greatly improved, the user obtains better driving experience, and meanwhile, the safety of the driving process is also improved.
