In this embodiment, the determination is made by whether the information to be used meets one of the vehicle-machine theme selection conditions.

Specifically, the selection conditions of the vehicle theme include the selection conditions of the environment information inside the vehicle, the selection conditions of the environment information outside the vehicle, the selection conditions of the driver information, and the selection conditions of the vehicle driving information;

Judging whether the information to be used meets one of the vehicle-machine theme selection conditions includes:

When at least one of the at least two pieces of information to be used in the acquired information meets the selection conditions of the in-vehicle environment information, the selection conditions of the external environment information, the selection conditions of the driver information, and the selection conditions of the vehicle driving One of the information selection conditions and the other information conforms to the selection conditions of the in-vehicle environment information, the selection conditions of the external environment information, the selection conditions of the driver information, and the selection conditions of the vehicle driving information in the selection conditions of the vehicle theme. One condition, it is determined that the information to be used meets the vehicle-machine theme selection condition.

More specifically, the environment information selection conditions in the vehicle include at least one of the following conditions: ambient light status information conditions, ambient light mode information conditions, and vehicle audio working information conditions;

The selection condition of the environment information outside the vehicle includes at least one of the following conditions: information condition of road congestion degree, information condition of scenery outside the vehicle;

In this way, when the number of screens in the cockpit increases, such as displaying the overall animation effect, such as boot animation or screen saver interface, it is necessary to perform image processing according to the screen opening status, and re-divide the display content, so that the display of different screens can be displayed as a whole.

For example, when the passenger of the co-pilot gets on the car and the screen of the co-pilot is turned on, at this time, the screen information of the input source changes, the number of screens is recognized to increase, and the whole vehicle is displayed in the state of multi-screen. Using the above method, the display of different screens can be displayed as a whole.

Referring to Fig. 3, the present application also provides a multi-screen-based car-machine theme segmentation method, the multi-screen-based car-machine theme segmentation method includes:

Step 201: Obtain the vehicle-machine theme to be switched through the above-mentioned automatic vehicle-machine theme switching method;

Step 202: Obtain the number of used screens, if the number of used screens is at least two, then

Step 203: Divide the subject of the car to be switched to form the same number of sub-screen theme pictures as the number of use screens. One theme sub-screen corresponds to one use screen, and one main part of the split-screen is used for one use screen.

In this embodiment, the theme of the car to be switched is divided to form a sub-screen theme picture with the same number of screens as the number of screens in use. A theme picture of a split-screen corresponds to a screen to be used and includes:

Divide the virtual screen to form the same number of split screen theme screens as the number of used screens.

Referring to Fig. 4, the present application also provides a car-machine theme segmentation device based on multi-screen, which includes a car-machine theme automatic switching device 21, a screen information acquisition module 22, and a screen information judging device. Module cutting module 23, car machine theme automatic switching device, 21 is the car machine theme automatic switching device as described above; Screen information acquisition module 22 is used to obtain the number of screens used; Screen information judgment module 23 is used to judge the number of screens used; Module 24 is used to divide the subject of the vehicle to be switched when the screen information judging module judges that the number of screens to be used is at least two, so as to form a sub-screen theme picture with the same number of screens as the number of used screens, one sub-screen theme picture and one Use screen correspondence.

Referring to Fig. 5, the present application also provides a car-machine theme display method, the car-machine theme display method includes:

Step 301: Obtain the vehicle-machine theme to be switched through the above-mentioned automatic vehicle-machine theme acquisition method;

Step 302: Sending the car-computer theme to be switched to the display screen for display.

In this embodiment, when the number of screens to be displayed is more than one, transmitting the theme of the vehicle to be switched to the display screen for display includes:

Obtain the display type of the car-machine theme to be switched, and the display type of the car-machine theme to be switched includes a split display type and a preset display type;

When the type to be displayed is a split display type, the above-mentioned multi-screen-based car-machine theme segmentation method is used to cut the car-machine theme to be switched so as to obtain a split-screen theme picture;

For example, a car theme may have two display modes, one of which is the default display type. For example, a car theme may have a default default mode (that is, the default display type), that is, the car The mobile phone theme has multiple backgrounds, and each background is applied to a display. For example, take a mobile phone theme based on Journey to the West as an example. It may have multiple backgrounds, and one of the backgrounds is Monkey King. The default display of the mobile phone theme In the method, the Monkey King background corresponds to the driver's display, and the pig Bajie's background corresponds to the co-pilot's display, that is, when the driver's display is turned on, the co-pilot's display is also turned on and the theme is selected, the background of the driver's display It is the background of Monkey King, and the background of the display of the co-pilot is the display background of Zhu Bajie.

When the driver selects the preset display type, the above method can be used to directly display the above corresponding background according to the number of displays used and the positions of the displays.

When the driver selects the type of split display, the above-mentioned car-machine theme segmentation method based on multi-screen can be used to cut the car-machine theme to be switched to obtain the split-screen theme picture, and send each split-screen theme picture to the corresponding display screen so that each display screen is displayed according to the obtained sub-screen theme picture.

For example, if a display theme is not preset, for example, it may be a photo taken by the driver himself as the background of the theme, then the background of the theme is segmented by the above-mentioned method, so as to be displayed by the above-mentioned method.

For another example, when the display theme is preset, for example, the above-mentioned Journey to the West theme, one of the backgrounds (such as the Monkey King background) can also be selected to be segmented and displayed by the above-mentioned method.

In this embodiment, the car-machine theme display method further includes:

For example, during the driving process, the co-pilot gets on and the co-pilot's display is turned on. At this time, the system detects that the use of the screen has increased, and then re-segments the theme of the car and re-displays it.
