Abstract

A display control device for controlling a display unit in a vehicle, including a dedicated middleware that executes a dedicated application program on a vehicle side, a general purpose middleware that executes a general purpose application program from an external of the vehicle, and an interface that exchanges necessary information between the dedicate middleware and the general purpose middleware, includes: an activation device that activates the dedicated middleware first, and activates the general purpose middleware after the dedicated middleware; and a dedicated display control device that displays, before an activation of the general-purpose middleware is completed, a dedicated menu screen for activating the dedicated application program on the display unit via the dedicated middleware when the dedicated application program on the dedicated middleware is available.

Claims

1. A display control device for controlling a display of a display unit mounted in a vehicle, including a dedicated middleware that executes a dedicated application program prepared on a vehicle side, a general purpose middleware that executes a general purpose application program delivered from an external of the vehicle, and an interface that exchanges necessary information between the dedicate middleware and the general purpose middleware, the display control device comprising:

an activation device that activates the dedicated middleware first on start-up, and activates the general purpose middleware after the dedicated middleware is activated; and

a dedicated display control device that displays, before an activation of the general-purpose middleware is completed by the activation device, a dedicated menu screen for activating the dedicated application program on the display unit via the dedicated middleware when the dedicated application program on the dedicated middleware is available.

2. The display control device according to claim 1, further comprising:

a general-purpose display control device that displays a general-purpose menu screen for activating the dedicated application program and the general-purpose application program on the display unit via the general-purpose middleware after the activation of the general-purpose middleware is completed.

3. The display control device according to claim 2, wherein:

when the activation of the general-purpose middleware is completed, the general-purpose display control device notifies the dedicated middleware of a completion of the activation, and displays the general-purpose menu screen on the display unit when the display is directed from the dedicated middleware.

4. The display control device according to claim 3, further comprising:

a display directing device that directs a display of the general-purpose menu screen when a predetermined condition is established in response to a notification of the completion of the activation from the general-purpose middleware.

5. The display control device according to claim 4, wherein:

the display directing device directs the display when the dedicated application program is not executed or when a user directs to stop executing the dedicated application program.

6. The display control device according to claim 1, wherein:

the dedicated display control device displays the dedicated menu screen on behalf of the general-purpose middleware when the general-purpose middleware does not notify a completion of the display of the general-purpose menu screen.

7. The display control device according to claim 3, wherein:

when the activation of the general-purpose middleware is completed, the dedicated middleware is notified of the completion of the activation via the interface.

8. (canceled)

9. A display control method for controlling a display of a display unit mounted on a vehicle, comprising:

activating a dedicated middleware that executes a dedicated application program prepared on a vehicle side first on start-up;

activating a general-purpose middleware that executes a general-purpose application program delivered from an external of the vehicle after the dedicated middleware is activated;

displaying, before an activation of the general-purpose middleware is completed, a dedicated menu screen for activating the dedicated application program on the display unit via the dedicated middleware when the dedicated application program on the dedicated middleware is available; and

exchanging necessary information between the dedicated middleware and the general-purpose middleware through an interface.
