Abstract

The present invention relates to an in-car computer system which comprises a control device 12 for displaying a main menu and plural sub-menus, each containing at least one selectable menu item, an operating unit 12 for selecting and activating a menu item within the main menu or sub-menu, and a switching member 20. A repeated operation of the switching member 20 causes the control device to activate the individual menu items HM1–HM4 of the main menu in a predetermined order.

Claims

1. An in-car computer system comprising:

a control device having a display for displaying a plurality of hierarchically arranged menus comprising a main menu having plural items and plural sub-menus, with each sub-menu containing at least one selectable menu item,

an operating unit for selecting and activating a menu item within the main menu or one of said sub-menus when said menu item is displayed on said display, and

a switching member, its repeated actuation causing the control device to activate the individual menu items of only the main menu in a predetermined order.

2. The in-car computer system of claim 1, wherein the operating unit is a rotary/push button.

3. The in-car computer system of claim 1, wherein an evaluation device is provided which registers the activation of menu items of the main menu and determines a frequency value for each menu item.

4. The in-car computer system of claim 3, wherein said control device determines the order according to the frequency values.

5. The in-car computer system of claim 1, wherein the order of menu item'"'"'s activation is adjustable.

6. The in-car computer system of claim 1, wherein the menu items intended for being displayed are selectable.

7. The in-car computer system of claim 1 wherein the display for each main menu item comprises one or more first sub-menu items and the display for each of said first sub-menu items comprises one or more second sub-menu items.

8. The in-car computer system of claim 1 wherein initial actuation of said switching member causes the display of said control device to display the first sub-menu items associated with a first predetermined one of said main menu items.

9. The in-car computer system of claim 8 wherein a second consecutive actuation of said switching member causes the display of said control device to display the first sub-menu items associated with a second predetermined one of said main menu items.

10. The in-car computer system of claim 1 wherein actuation of the switching member activates the main menu items regardless of the particular menu being displayed when the switching member is actuated.

11. A method for selecting and activating menu items from a plurality of hierarchically arranged menus displayed on the display of an in-car computer system, the plurality of menus comprising a main menu with at least two main menu items and at least a sub-menu with at least two sub-menu items, wherein by actuating a switching member the main menu items only are selected and activated consecutively, regardless of the particular menu being displayed when said switching member is initially actuated.

12. The method of claim 11, wherein said order of selection and activation of the main menu items is adjustable by actuating the switching member.

13. The method of claim 12, wherein said order is determined according to a frequency value of the main menu items used.

14. The method of claim 11, wherein after actuating the switching member and selecting and activating a sub-menu item said order starts again from the beginning with respect to selection and activation of the main menu items.
