Abstract

A vehicle multimedia system includes a display that displays a hierarchically structured menu. The hierarchically structured menu may have a main menu, a plurality of submenus, and menu items. The multimedia system provides a memory for storing information identifying a menu or menu item, and a memory control unit for writing information related to a menu item upon a user'"'"'s selection of the menu by an operating element or by automatic return to a main menu, and displaying the information as selectable menu items identified by the information.

Claims

1. A method for controlling the display of hierarchically structured menus where each menu includes at least one menu item for being selected and activated comprising:

displaying a menu on a display of a vehicle multimedia system;

determining, with a control unit, whether a predetermined criterion corresponding to a displayed menu or menu item is satisfied;

the control unit storing information identifying the displayed menu or menu item in response to an activation of a menu item or in response to an automatically caused return to a predetermined menu;

reading, with the control unit, information stored in response to an operation of an operating element; and

the control unit displaying the read information as selectable and activatable menu items on the display, where the selection and activation of the menu item allows the display of the menu or menu item identified by the information;

wherein the information identifying the displayed menu or menu item is selectively stored based on the predetermined criterion such that the information is stored if the criterion is satisfied and the information is not stored if the criterion is not satisfied.

2. The method of claim 1 where the return to a predetermined menu occurs after a predetermined period of time.

3. The method of claim 1 where the predetermined menu is a main menu or main status screen.

4. The method of claim 1 where the memory element is selected from the group consisting of:

a flash memory, a non-volatile memory, and a hard-disk memory.

5. The method of claim 1 wherein the predetermined criterion is a menu type or menu item type and wherein:

the information identifying the displayed menu or menu item is stored in response to a determination, based on the menu type or menu item type, that the displayed menu or menu item activates a function; and

the information identifying the displayed menu or menu item type is not stored in response to a determination, based on the menu type or menu item type, that the displayed menu or menu item displays a submenu.

6. The method of claim 1 wherein a first action is performed in response to a long operation of the operating element and a second action is performed in response to a short operation of the operating element.

7. The method of claim 6 wherein the first action returns to a selected menu in the hierarchically structured menus and the second action returns to and activates a selected menu item.

8. The method of claim 1 where the information is adjustable.

9. The method of claim 8 further comprising:

the control unit storing the information in a memory organized as a ring memory; and

overwriting one or more old memory entries by one or more new entries if the memory is full.

10. The method of claim 9 where the stored information is capable of deletion by the user.

11. A computer program product comprising:

a non-transitory computer useable medium having a computer readable code means embodied in the medium for controlling the display of hierarchically structured menus on a display of a vehicle multimedia system, the computer readable program code in the computer program product comprising;

computer readable program code means for causing a control unit to display a menu on the display;

computer readable program code means for determining whether a predetermined criterion corresponding to a displayed menu or menu item is satisfied;

computer readable program code means for causing a memory control unit to store information identifying the displayed menu or menu item in response to an activation of a menu item or in response to an automatically caused return to a predetermined menu;

computer readable program code means for causing the memory control unit to read information stored in response to an operation of an operating element;

computer readable program code means for causing the control unit to display the read information as selectable and activatable menu items on the display, where the selection and activation of the menu item allows the display of the menu or menu item identified by the information; and

computer readable program code means for causing the control unit to selectively store the information identifying the displayed menu or menu item based on a predetermined criterion such that the memory control unit stores the information if the criterion is satisfied and the memory control unit does not store the information if the criterion is not satisfied.

12. The computer program product of claim 11 further comprising:

computer readable program code means for causing the memory control unit to store the information in a memory; and

computer readable program code means for causing the memory control unit to overwrite one or more old memory entries by one or more new entries if the memory is full.

13. The method of claim 12 where the memory is organized as a ring memory.

14. The computer program product of claim 11 wherein the predetermined criterion is a menu type or menu item type and the computer program product further comprising:

computer readable program code means for causing the memory control unit to store the information identifying the displayed menu or menu item in response to a determination, based on the menu type or menu item type, that the displayed menu or menu item activates a function; and

computer readable program code means for causing the memory control unit not to store the information identifying the displayed menu or menu item in response to a determination, based on the menu type or menu item type, that the displayed menu or menu item displays a submenu.

15. The computer program product of claim 11 further comprising:

computer readable program code means for performing a first action in response to a long operation of the operating element; and

computer readable program code means for performing a second action in response to a short operation of the operating element.

16. The computer program product of claim 15 wherein the first action returns to a selected menu in the hierarchically structured menus and the second action returns to and activates a selected menu item.

17. A method of controlling the display of hierarchically structured menus comprising:

driving a display of a vehicle multimedia system with a control unit to display a menu comprising menu items;

determining, with the control unit, whether a predetermined criterion corresponding to a displayed menu or menu item is satisfied;

the control unit selectively storing information identifying the displayed menu or menu item in response to the predetermined criterion being satisfied, and at least one of activation of a menu item or an automatically caused return to a predetermined menu, the information being selected for storage in response to the predetermined criterion being satisfied and the information not being selected for storage in response to the predetermined criterion not being satisfied;

reading, with the control unit, the selectively stored information in response to an operation of an operating element; and

the control unit driving the display to display the read information as the menu or menu item identified by the information.

18. The method of claim 17, where the displayed menu or menu item is the last accessed menu or menu item.

19. The method of claim 17, where the control unit driving the display further comprises the initial step of the control unit driving the display to display at least one of selectable or activatable menu or menu items, where the selection or activation of the at least one of selectable or activatable menu or menu items allows the display of the menu or menu items identified by the information.

20. The method of claim 17, further comprising the control unit overwriting previously stored information with the information, the previously stored information selected by the control unit for overwriting based on being stored the longest.
