Abstract

A vehicle steering wheel is provided with a thin reconfigurable display such as an LED, an LCD, an electro-luminescent display, or other types of reconfigurable thin display. Vehicle instrument information such as speedometer, fuel level, vehicle temperature, engine speed, etc. are provided on this display. The reconfigurable display is provided with a control that reconfigures the location of the information on the display. The control is provided with a signal indicative of rotation of the steering wheel, and the control takes that signal and adjusts the information such that the displayed information maintains a particular orientation relative to the horizontal during a turn. With the present invention, the vehicle operator need only consult the vehicle steering wheel to obtain information about the vehicle condition. There are thus less constraints on the design of the steering wheel, and in the requirement of providing visual access to the instrument panel.

Claims

1. A vehicle steering wheel comprising:

a steering wheel body having a central portion and an outer rim connected for rotation with said central portion;

a reconfigurable display unit placed on said central portion, and rotating with said central portion and said outer rim; and

a control for providing information to said display unit, said control causing said display unit to display said information on said central portion of said steering wheel, said control monitoring rotation of said steering wheel body and reconfiguring the orientation of said display information on said display unit to maintain said information relatively horizontal in orientation relative to an operator.

2. A steering wheel as recited in claim 1, wherein said control stops reconfiguring orientation once a predetermined range of turn has been exceeded.

3. A steering wheel as recited in claim 1, wherein said control rotating said information on said display unit in response to rotation, but not causing said information to move relative to said wheel.

4. A steering wheel as recited in claim 1, wherein said control maintaining said information in an approximately stationary position in space during rotation.

5. A steering wheel as recited in claim 4, wherein said control scrolling some information off of said display unit during rotation.

6. A steering wheel as recited in claim 1, wherein said control assigning a hierarchy of a higher level to at least some elements of said information, and maintaining said higher level information elements displayed on said display at a prominent location during a turn.

7. A method of providing information to a vehicle operator comprising the steps of:

1) providing a vehicle steering wheel having a reconfigurable display which rotates with said vehicle steering wheel, and a sensor for sensing rotation of said steering wheel;

2) monitoring rotation of said steering wheel with said sensor, and providing a signal of said steering wheel turning to a control for said display;

3) reconfiguring said display to adjust for rotation of said steering wheel such that said displayed information maintain a particular orientation relative to the horizontal during the turning of said steering wheel.

8. A method as recited in claim 7, wherein said reconfiguration includes moving said displayed information such at least some elements of said displayed information maintain a relatively constant location in space during said rotation.

9. A method as recited in claim 7, wherein an upper limit of rotation is set, and further reconfiguration under step 3) is ceased when said upper limit is exceeded.

10. A method as recited in claim 7, wherein said reconfiguration of step 3) includes maintaining the orientation of elements of said displayed information generally parallel relative to the horizontal.

11. A vehicle steering wheel comprising:

a vehicle steering wheel body having a central portion and an outer rim connected for rotation with said central portion;

a reconfigurable display unit placed on said central portion to rotate with said central portion and said outer rim;

a sensor for monitoring rotation of said steering wheel body; and

a control receiving signals from said sensor, said control controlling the information to be displayed on said display unit, said control unit causing said display to display information on said central portion of said steering wheel with regard to operational information of said vehicle, and said control reconfiguring the orientation of said displayed information in response to signals from said sensor to maintain a relatively constant horizontal orientation.

12. A vehicle steering wheel as recited in claim 11, wherein said display unit comprises an LED.

13. A vehicle steering wheel as recited in claim 11, wherein said display unit is an LCD.

14. A vehicle steering wheel as recited in claim 12, wherein said control includes an upper limit, and once said amount of rotation exceeds said upper limit, further reconfiguration of said displayed information is ceased.
