Abstract

A control system for a vehicle with a plurality of selectively variable characteristics includes a first button depressible to cause a first mode of operation and a second button depressible to cause a second mode of operation. In the first mode of operation, a rotary dial is rotatable to cause variation of the first characteristic. In the second mode of operation, the rotary dial is rotatable to cause variation of the second characteristic. The control system thus enables a single dial to control multiple characteristics or multiple vehicle systems, which enables a corresponding reduction in the quantity of switches and other control input devices in a vehicle passenger compartment.

Claims

1. A multifunction control and display system by which a vehicle operator may control multiple vehicle systems comprising:

a display screen having a plurality of screen quadrants, and at least one display window superimposed between the quadrants;

each of the screen quadrants displaying information about the operating conditions of one of the vehicle systems;

an input interface having an input device corresponding to each of the screen quadrants of the display screen and at least one input knob located centrally of the quadrants,

and a controller that responds to the operator actuating one of the quadrant input devices by enabling the at least one input knob to adjust an operating characteristic of the vehicle system associated with that quadrant.

2. The multifunction control and display system of claim 1 wherein the controller further causes the particular display screen quadrant that displays the information relating to that vehicle system that is adjusted by the input knob to display updated information regarding that operating characteristic that is adjusted by the operator actuation of the input knob.

3. The multifunction control and display system of claim 1 in which the display window displays information about the operating characteristic that has been most recently adjusted by actuating the knob.

4. The multifunction control and display system of claim 3 in which the input interface includes an inner knob and an outer knob by which two operating characteristics of the selected vehicle system may be adjusted.

5. The multifunction control and display system of claim 4 in which the at least one display window includes an inner window that displays information regarding the characteristic that is adjusted by the inner knob and an outer window that displays information regarding the characteristic that is adjusted by the outer knob.

6. The multifunction control and display system of claim 1 in which a plurality of auxiliary buttons are provided on the input interface and a like plurality of corresponding auxiliary display screens are provided, and the controller responds to the operator actuation of a particular input device by enabling the actuation of a selected one of the auxiliary button to select the operating characteristic that I shown on the corresponding auxiliary display screen.

7. The multifunction control and display system of claim 1 in which the input interface of each quadrant is a switch.

8. The multifunction control and display system of claim 1 in which the input interface of each quadrant is a gesture pad.

12. The multifunction control and display system of claim 1 wherein the controller further causes the particular display screen quadrant that displays the information relating to that vehicle system that is adjusted by the input knob or gesture pad to display updated information regarding that operating characteristic that is adjusted by the chosen operator actuation.

9. A multifunction control and display system by which a vehicle operator may control multiple vehicle systems comprising:

a display screen having a plurality of screen quadrants, and at least one display window superimposed between the quadrants;

each of the screen quadrants displaying information about the operating conditions of one of the vehicle systems;

an input interface having a gesture pad input device corresponding to each of the screen quadrants of the display screen and at least one input knob located centrally of the screen quadrants,

and a controller that responds to the operator actuating one of the quadrant input devices by enabling the at least one input knob to adjust an operating characteristic of the vehicle system associated with that quadrant.

10. The multifunction control and display system of claim 9 in which the operator may use the gesture pad to adjust the operating characteristic as an alternative to using the input knob to adjust the operating characteristic.

11. The multifunction control and display system of claim 10 in which the operator'"'"'s first touch of one of the quadrant gesture pads instructs the controller to accept a next touch as an instruction to adjust an operating condition of the vehicle system corresponding to the particular quadrant and then the next touch by operator adjusts the operating condition.

13. The multifunction control and display system of claim 9 in which the input interface includes an inner knob and an outer knob by which two operating characteristics of the selected vehicle system may be adjusted.

14. The multifunction control and display system of claim 13 in which the at least one display window includes an inner window that displays information regarding the characteristic that is adjusted by the inner knob and an outer window that displays information regarding the characteristic that is adjusted by the outer knob.
