Abstract

A method of communicating between an in-vehicle infotainment (IVI) device in a vehicle and a mobile terminal. The method includes receiving, via a communication unit of the IVI device, application data from the mobile terminal for executing a prescribed application on the IVI device; displaying, via a display of the IVI device, one of a first execution screen having a first execution depth and a second execution screen having a second execution depth higher than the first execution depth for the prescribed application; receiving an interrupt request for requesting the one of the first and second execution screens stopped being displayed; displaying, via the display of the IVI device, the first execution screen having the first execution depth in response to the second execution screen being displayed when receiving the interrupt request; and displaying, via the display of the IVI device, a list of certified applications certified for the IVI device or switch a launcher application to a foreground, in response to the first execution screen being displayed when receiving the interrupt request.

Claims

1. A method of communicating between an in-vehicle infotainment (IVI) device in a vehicle and a mobile terminal using MirrorLink, the method comprising:

receiving, via a communication unit of the IVI device, application data from the mobile terminal for executing a prescribed application on the IVI device;

displaying, via a display of the IVI device, one of a first execution screen having a first execution depth, a second execution screen having a second execution depth higher than the first execution depth for the prescribed application, and a third execution screen having a third execution depth higher than the second execution depth for the prescribed application, wherein the first execution screen corresponds to displaying a list of music items to be played on the IVI device, the second execution screen corresponds to displaying a play screen and the third execution screen corresponds to displaying a current play list;

receiving an interrupt request for requesting the one of the first, second and third execution screens stopped being displayed;

displaying, via the display of the IVI device, the first execution screen having the first execution depth in response to receiving the interrupt request while displaying the second execution screen, and displaying the second execution screen having the second execution depth in response to receiving the interrupt request while displaying the third execution screen;

determining whether or not a launcher application exists in response to receiving the interrupt request while displaying the first execution screen;

displaying, via the display of the IVI device, a list of certified applications certified for the IVI device if it is determined that the launcher application does not exist; and

switching the launcher application to a foreground and displaying the execution screen of the launcher application if it is determined that the launcher application exists.

2. The method of claim 1, wherein the first execution screen having the first execution depth corresponds to displaying a list of items to be executed on the IVI device.

3. The method of claim 2, wherein the second execution screen having the second execution depth corresponds to executing an application corresponding to a selected item and displaying the second execution screen corresponding to the executing application.

4. The method of claim 1, wherein the interrupt request is caused by a touch input of either a home button or a cancel button on the IVI device or the mobile terminal.

5. The method of claim 1, wherein the first execution screen is an initial execution screen of the prescribed application.

6. The method of claim 1, wherein the prescribed application corresponds to a music playing function.

7. The method of claim 1, further comprising:

receiving another interrupt request when the launcher application is switched to the foreground, said launcher application including an initial launcher screen and a setting screen for customizing the initial launcher screen; and

displaying, via the display, the initial launcher screen in response to the setting screen being displayed when receiving the other interrupt request.

8. An in-vehicle infotainment (IVI) device for communicating with a mobile terminal by using MirrorLink, comprising:

a communication unit configured to receive application data from the mobile terminal for executing a prescribed application on the IVI device;

a display configured to display one of a first execution screen having a first execution depth, a second execution screen having a second execution depth higher than the first execution depth for the prescribed application, and a third execution screen having a third execution depth higher than the second execution depth for the prescribed application, wherein the first execution screen corresponds to displaying a list of music items to be played on the IVI device, the second execution screen corresponds to displaying a play screen and the third execution screen corresponds to displaying a current play list; and

a controller configured to;

receive an interrupt request for requesting the one of the first, second and third execution screens stopped being displayed,

display the first execution screen having the first execution depth on the display, in response to receiving the interrupt request while displaying the second execution screen, and display the second execution screen having the second execution depth in response to receiving the interrupt request while displaying the third execution screen,

determine whether or not a launcher application exists in response to receiving the interrupt request while displaying the first execution screen,

display, via the display of the IVI device, a list of certified applications certified for the IVI device if it is determined that the launcher application does not exist, and

switch the launcher application to a foreground and display the execution screen of the launcher application if it is determined that the launcher application exists.

9. The IVI device of claim 8, wherein the interrupt request is caused by a touch input of either a home button or a cancel button on the IVI device or the mobile terminal.

10. The IVI device of claim 8, wherein the controller is further configured to:

receive another interrupt request when the launcher application is switched to the foreground, said launcher application including an initial launcher screen and a setting screen for customizing the initial launcher screen, and

display the initial launcher screen on the display, in response to the setting screen being displayed when receiving the other interrupt request.

11. A mobile terminal for communicating with an in-vehicle infotainment (IVI) device by using MirrorLink, comprising:

a communication unit configured to transmit application data to the IVI device for executing a prescribed application on the IVI device; and

a controller configured to;

control a display of the IVI device to display one of a first execution screen having a first execution depth, a second execution screen having a second execution depth higher than the first execution depth for the prescribed application, and a third execution screen having a third execution depth higher than the second execution depth for the prescribed application, wherein the first execution screen corresponds to displaying a list of music items to be played on the IVI device, the second execution screen corresponds to playing a music file corresponding to a selected music item and displaying the second execution screen corresponding to the playing music file, and the third execution screen corresponds to displaying a play list,

receive an interrupt request for requesting the one of the first, second and third execution screens stopped being displayed,
