Abstract

An improved display for steering wheels places display elements on the rim of the steering wheel. In this way, an operator of a vehicle is less likely to ignore display elements such as turn signals or warning lights. In one embodiment, lights are utilized to display the informational element. In a second embodiment a reconfigurable thin display, such as an LED, an LCD or an electro-luminescent display, is utilized. In either embodiment, the displayed information may change with rotation of the steering wheel.

Claims

1. A vehicle steering wheel comprising:

a hub and a rim surrounding said hub, at least one spoke connecting said hub and said rim;

a control receiving an indication of an upcoming turn; and

a display mounted on said rim, said display communicating with said control such that said display provides a turn signal on said rim.

2. A steering wheel as recited in claim 1, wherein said display is a light.

3. A steering wheel as recited in claim 1, wherein said display is a reconfigurable thin display.

4. A steering wheel as recited in claim 1, wherein said display further displays warning signals.

5. A display as recited in claim 1, wherein said control receives feedback of rotation of said steering wheel.

6. A steering wheel as recited in claim 5, wherein said display is adjusted with rotation of said steering wheel to maintain display elements prominent to a vehicle operator.

7. A steering wheel as recited in claim 6, wherein after a predetermined amount of turning, said control no longer adjusts said display.

8. A steering wheel as recited in claim 6, wherein said displayed elements move in opposition to rotation of said wheel such that it maintains a generally constant position in space.

9. A steering wheel as recited in claim 6, wherein said display is an LED display.

10. A steering wheel as recited in claim 6, wherein said display is an LCD display.

11. A method of displaying information on a vehicle comprising the steps of:

(1) providing a steering wheel, and display on a rim of said steering wheel;

(2) providing a control sensing an indication from the operator of an upcoming turn, said control controlling the display on said display on said rim; and

(3) displaying a turn signal on said rim of said steering wheel when an operator has indicated an upcoming turn.

12. A method as recited in claim 11, further including the steps of monitoring rotation of said steering wheel, and moving the location of said displayed turn signal on said rim with a turn to maintain a generally constant location for said displayed turn signal.

13. A method as recited in claim 12, further comprising the step of setting an upper limit for adjustment of said display, and ceasing further adjustment of said display if said wheel turns beyond said limit.

14. A vehicle steering wheel comprising:

a hub and a rim surrounding said hub, at least one spoke connecting said hub and said rim;

a control receiving an indication of an upcoming turn;

a sensor for sensing rotation of said wheel, said sensor providing a signal of amount of turn of said wheel to said control; and

a reconfigurable thin display mounted on said rim, said display communicating with said control such that said display provides an indication of turn signals on said rim.

15. A vehicle steering wheel as recited in claim 14, wherein said display further displays warning signals.
