Abstract

An electronic apparatus provided with a bidirectional rotary switch having a control element for selecting individual function elements of function groups by rotation of the control element, and for activating the individual function elements by pushing the control element, and where the selected or activated function group and/or a function is exited by pulling the control element.

Claims

1. An electronic system for selecting and activating functions from different groups of functions and for activating an apparatus, the system comprising:

a display which shows different functions arranged in function groups, each function representing the implementation of an apparatus function;

a bidirectional control element being actuable in a rotary direction and capable of being pushed or pulled, the control element being coupled to the display, wherein a function shown on the display is selected by rotating the control element and the function is activated by pushing the control element and the last activated function is exited by pulling the control element.

2. The electronic system of claim 1, wherein the control element is a rotary knob.

3. The electronic system of claim 1, wherein the function groups are hierarchically structured and that a respective pulling motion of the control element addresses a respective higher level function group.

4. The electronic system of claim 1 wherein a respective function group with individual function elements is associated with each of the individual functions and a respective pulling motion of the control element is provided so as to switch back and forth between the function and the function group associated with the function.

5. The electronic system of claim 1, wherein the control element is biased in the direction of a central position so that the control element automatically returns to the central position when it is released.

6. The electronic system of claim 1, wherein the control element is coupled to an increment member which subdivides the rotation of the control element into discrete steps.

7. The electronic system of claim 1, wherein the apparatus is a vehicle, and the functions further comprise:

a navigation function which causes the vehicle to display position data when the navigation function is activated by the control element;

an on-board computer function which causes the vehicle to measure and display vehicle operation data when the on-board computer function is activated by the control element; and

a radio function which causes the vehicle to activate a radio when the radio function is activated by the control element.

8. The electronic system of claim 1, wherein the apparatus is an automotive data system and the functions further comprise:

a map function which causes the automotive data system to display a map on the display when the map function is activated by the control element;

a navigation function which causes the automotive data system to display information relating to the distance and direction of a location when the navigation function is activated by the control element; and

an information function which causes the automotive data system to display data relating to a location when the information function is activated by the control element.

9. A control system for allowing a user to select and control the functions of different apparatus, the system comprising:

a bidirectional control element capable of being pushed or pulled;

a first apparatus having at least two different functions coupled to the control element;

a second apparatus having at least two different functions coupled to the control element;

wherein a function of the first apparatus is selected by rotating the control element to select a first function group sub-menu, said selected function is activated by pushing the control element and deactivated by pulling the control element; and

wherein a function of the second apparatus is selected by rotating the control element to select a second function group sub-menu, said selected function is activated by pushing the control element and deactivated by pulling the control element.

10. The control system of claim 9, wherein the control element is a rotary knob.

11. The electronic system of claim 9, wherein the control element is biased in the direction of a central position so that the control element automatically returns to the central position when it is released.

12. The electronic system of claim 9, wherein the control element is coupled to an increment member which subdivides the rotation of the control element into discrete steps.

13. The control system of claim 9 further comprising a display, the display showing the first function group sub-menu when the first function group is selected by the control element, and showing the second function group sub-menu when the second function group is selected by the control element.
