Device for controlling vehicle display device, system having the same, and method for controlling vehicle display device

1. A device for controlling a vehicle display device, the controlling device comprising:

a processor configured to adjust a screen size of the vehicle display device based on a vehicle driving condition and an input from a user; and

a storage configured to store information determined by the processor,

wherein:

the vehicle driving condition includes an autonomous driving mode and a normal driving mode, and

the input from the user includes at least one of a request of use of a navigation function, a request of use of a multimedia function, and a request of use of a rear side monitoring function, and

wherein after the autonomous driving mode is deactivated, and when the use of the navigation function or the multimedia function, and the rear side monitoring function are requested from the user, the processor is configured to:

physically enlarge the screen size of the vehicle display device into a first stage size in a first direction, and subsequently and physically enlarge the first stage size of the screen size into a second stage size in the first direction, and

physically enlarge the second stage size of the screen size of the vehicle display device into a third stage size in a second direction.

2. The controlling device of claim 1 , wherein when a vehicle starting is turned off, or when the vehicle driving condition is the autonomous driving mode, the processor is configured to turn off the vehicle display device.

3. The controlling device of claim 1 , wherein the first direction and the second direction are opposite to each other.

4. The controlling device of claim 1 , wherein when a rear monitoring switch is turned on or a left-turn signal is activated, the processor is configured to determine that request of the use of the rear side monitoring function has occurred.

5. The controlling device of claim 1 , wherein when, after deactivation of the autonomous driving mode, request from the user to use the rear side monitoring function is received without the request to use the navigation function or the multimedia function, the processor is configured to physically enlarge the screen size of the vehicle display device into the first stage size in the first direction, and subsequently into the third stage size.

6. A vehicle system comprising:

a vehicle display device configured to roll a display screen; and

a controlling device configured to control the vehicle display device,

wherein the controlling device is configured to adjust a screen size of the vehicle display device depending on a vehicle driving condition and an input from a user,

wherein:

the vehicle driving condition includes an autonomous driving mode and a normal driving mode, and

the input from the user includes at least one of a request of use of a navigation function, a request of use of a multimedia function, and a request of use of a rear side monitoring function,

the vehicle display device includes:

a first display screen to be physically enlarged in a first direction when the autonomous driving mode is deactivated;

a second display screen to be subsequently and physically enlarged in a second direction when the autonomous driving mode is deactivated, and when the use of the navigation function or the multimedia function, and the rear side monitoring function are requested from the user; and

a rod-shaped rolling mechanism configured to roll the first display screen and the second display screen.

7. The vehicle system of claim 6 , wherein the rod-shaped rolling mechanism includes:

a driving motor configured to extend and roll the first display screen and the second display screen;

a rail moving portion configured to fix the first and second display screens, wherein the rail moving portion is movable by the driving motor; and

a rail body surrounding the rail moving portion.

8. A method for controlling a vehicle display device, the method comprising:

determining, by a processor, a vehicle driving condition; and

adjusting, by the processor, a screen size of the vehicle display device based on the determined vehicle driving condition, and a user input,

wherein:

the vehicle driving condition includes an autonomous driving mode and a normal driving mode,

the user input includes at least one of a request of use of a navigation function, a request of use of a multimedia function, and a request of use of a rear side monitoring function, and

wherein adjusting the screen size of the vehicle display device includes:

after the autonomous driving mode is deactivated, and when the use of the navigation function or the multimedia function, and the rear side monitoring function are requested from a user,

physically enlarging the screen size of the vehicle display device into a first stage size in a first direction;

subsequently and physically enlarging the first stage size of the screen size into a second stage size in the first direction; and

physically enlarging the second stage size of the screen size of the vehicle display device into a third stage size in a second direction.

9. The method of claim 8 , wherein adjusting the screen size of the vehicle display device includes:

when a vehicle starting is turned off, or when the vehicle driving condition is in the autonomous driving mode, turning off the vehicle display device.

10. The method of claim 8 , wherein determining the vehicle driving condition includes:

determining at least one of whether the vehicle is in the autonomous driving mode, whether the rear side monitoring function is requested, whether the navigation function is used, or whether the multimedia function is used.
