In this embodiment, the target terminal is a vehicle-mounted information terminal.
In order to ensure the display effect of each screen, and meanwhile, the system overhead is considered, the maximum number of the split screens m (m is more than or equal to 2) of the target terminal is determined according to the size and resolution of the display screen of the target terminal and the processing capacity of the system, and generally, the number of the split screens is not more than 10. For example, if the display screen of the target terminal is 17 inches, it is generally appropriate to have 3 split screens (including a projection screen interface, a telematics terminal program interface) that are allowed to be displayed.
And 2, receiving a screen throwing request of at least one request end, and displaying a screen throwing interface on the target terminal in a full-screen mode.
In this embodiment, the request end refers to a terminal that initiates a screen-throwing request, for example, a mobile phone or the like.
In this embodiment, the request end throws the screen to the target terminal through WIFI.

And step 3, reading all levels of split screen man-machine interaction interfaces corresponding to the application programs currently operated by the target terminal according to the maximum split screen number, and storing the split screen man-machine interaction interfaces in a display cache.
Storing all levels of split screen human-computer interaction interfaces corresponding to the prefabricated application programs, and reading the corresponding levels of split screen human-computer interaction interfaces after the maximum split screen number m is determined.
The split corresponding to the maximum split number m is called the maximum split.
For example, if the application program operated by the current target terminal is radio, and the maximum number m of split screens is 3, two man-machine interaction interfaces of 2 split screens and 3 split screens (maximum split screens) of radio are read into the display cache.
And step 4, receiving a split screen request initiated by a request terminal, judging whether the request terminal is a screen throwing terminal, if yes, entering a step 5, otherwise, entering a step 7.

In this embodiment, the screen-throwing end is a terminal that has thrown its own interface to the target terminal.
And 5, judging whether a target terminal program interface is displayed, if so, sending out information of failure in split screen, otherwise, entering the next step.
And step 6, judging whether the current number of split screens reaches the maximum number of split screens, if so, displaying the target terminal program interface according to a first preset rule, otherwise, displaying the target terminal program interface according to a second preset rule.
In this embodiment, the first preset rule is:
and A1, judging whether the request end is a priority screen throwing end, if so, entering a step A2, otherwise, entering a step A4.
In this embodiment, the priority screen-throwing end is a corresponding state of the priority request end after the interface is thrown to the target terminal.
And the common screen-throwing end corresponds to the state of the common request end after the interface is thrown to the target terminal.
That is, the screen-throwing end is also a request end when the screen-throwing request is initiated.

For example, as shown in fig. 2, the current target terminal display screen is a 3-split screen (k=m=3), the common screen-throwing interface A, B displays music and navigation respectively, the preset priority is navigation and music, and when the priority request end initiates a split screen request, the common screen-throwing interface a is covered by the target terminal program interface of the 3-split screen.
Step A4, sequentially initiating a screen-throwing-out request to all the current common screen-throwing terminals, if the common screen-throwing terminals for exiting the screen throwing exist within a preset time, reading a maximum screen-dividing man-machine interaction interface of an application program or a default application program currently operated by a target terminal from the display cache, replacing the screen-throwing interface of the common screen-throwing terminals for exiting the screen throwing, and switching an interface focus to the target terminal program interface; if no common screen throwing end exits the screen throwing, sending out the information of failed screen throwing request.
In this embodiment, the preset time is 1 to 5 seconds.
For example, as shown in fig. 3, the current target terminal display screen is 3 split screens (k=m=3), the screen-throwing interfaces of the common screen-throwing end A, B respectively display music and navigation, at this time, the request end a initiates a screen-splitting request, then the screen-throwing end (the priority screen-throwing end, the common screen-throwing end a and the common screen-throwing end B) which has been thrown at present is sequentially inquired whether to exit the screen-throwing, if the common screen-throwing end B accepts to exit the screen-throwing, the screen-throwing interface of the common screen-throwing end B is replaced by the target terminal program interface of 3 split screens.
In this embodiment, the second preset rule is:
and B1, acquiring the current split screen number k, and determining that the split screen number is k+1.
And B2, reading the split-screen human-computer interaction interfaces of the target terminal program corresponding to the number of the split screens from the cache, displaying the split-screen human-computer interaction interfaces at a preset split-screen position, and switching the interface focus to the target terminal program interface.

As shown in fig. 4, the current target terminal display screen is a 2-split screen (k=2), the screen-throwing interface of the priority screen-throwing end is displayed on the left side, and the common screen-throwing interface a is displayed on the right side. If the request end A initiates the split screen request again, the target terminal program interface of 3 split screens is read from the cache and displayed on the right side, and the focus of the interface is switched to the target terminal program interface because the common screen-throwing interface A is displayed but the target terminal program interface is not displayed
And 7, judging whether the current split screen number reaches the maximum split screen number, if so, displaying the screen throwing interface of the request terminal according to a third preset rule, otherwise, displaying the screen throwing interface of the request terminal according to a fourth preset rule.

and C1, judging whether the request end is a priority request end, if so, entering a step C2, otherwise, entering a step C4.
In this embodiment, the priority request end is a request end of a driver; correspondingly, the request ends except the driver are common request ends;
and C2, acquiring the content types of all the current common screen-throwing interfaces, and determining the common screen-throwing interface with the lowest priority according to the preset content type priority.
And C3, covering the common screen-throwing interface with the lowest priority by using the screen-throwing interface of the priority request terminal, and switching an interface focus to the screen-throwing interface of the priority request terminal.
For example, as shown in fig. 5, the current target terminal display screen is a 3-split screen (k=m=3), the common screen-throwing interface A, B, C displays music, navigation and a main page respectively, and the preset priorities are navigation, a main page and music, and when the priority request terminal initiates a split screen request, the common screen-throwing interface a is covered by the screen-throwing interface of the priority request terminal.
Step C4, sequentially initiating a request for exiting the screen to all the current common screen-throwing terminals, if the common screen-throwing terminals exiting the screen-throwing terminals exist within a preset time, replacing the common screen-throwing interface of the screen-throwing terminals exiting the screen-throwing terminals with the screen-throwing interface of the request terminal, and switching the interface focus to the screen-throwing interface of the request terminal; if no screen throwing end exits the screen throwing, sending out information of failed screen throwing request.
For example, as shown in fig. 6, the current target terminal display screen is 3 split screens (k=m=3), the common screen-throwing interfaces B respectively display videos, when the request end D initiates a split screen request, then the common screen-throwing end B is inquired whether to exit the screen throwing, and if the common screen-throwing end B accepts to exit the screen throwing, the common screen-throwing interface B is replaced by the screen-throwing interface of the request end D.
In this embodiment, the fourth preset rule is:
and D1, acquiring the current split screen number k, and determining that the split screen number is k+1.
And D2, displaying the screen-throwing interface of the request end at a preset screen-splitting position, and switching an interface focus to the screen-throwing interface of the request end initiating the screen-splitting request.
In this embodiment, the preset split screen position is one of the rightmost, leftmost, topmost and bottommost.
As shown in fig. 7, the current target terminal display screen is a 2-split screen (k=2), the screen-throwing interface of the priority screen-throwing end is displayed on the left side, and the common screen-throwing interface a is displayed on the right side. If the request end B initiates a split screen request, the number of split screens at this time is determined to be 3 because the screen-throwing interface of the request end B is not displayed, the screen-throwing interface of the request end B is displayed in the split screen at the rightmost side, and the interface focus is switched to the common screen-throwing interface B.
