Abstract

Visual indicators on a steering wheel of a vehicle provide information to a driver of the vehicle. In one embodiment an input stage is used to receive an input signal. The signal is processed to provide a signal for an indicator on the steering wheel. Conditions of the steering wheel can be sensed to provide modification of the indicator display. For example, the rotation or orientation of the steering wheel can be taken into account to modify the display for better viewing. The position or placement of a driver'"'"'s hand on the steering wheel can be used to change the display of indicators so that the indicators are less obscured.

Claims

1. An apparatus for displaying information to a vehicle'"'"'s driver, the apparatus comprising:

an input stage for receiving an input signal about a condition; and

an indicator mounted onto a steering wheel of the vehicle, wherein the indicator is coupled to the input stage and displays an indication of the condition in response to the input signal.

2. The apparatus of claim 1, wherein the indicator includes a light emitting diode.

3. The apparatus of claim 1, wherein the indicator is arranged on a touch screen.

4. The apparatus of claim 3, wherein the touch screen includes a liquid crystal display.

5. The apparatus of claim 1, wherein the information includes outside temperature.

6. The apparatus of claim 1, wherein the information includes operations-related information of the vehicle.

7. The apparatus of claim 6, wherein the operations-related information includes a speed of the vehicle.

8. The apparatus of claim 6, wherein the operations-related information of the vehicle includes a distance covered by the vehicle.

9. The apparatus of claim 6, wherein the operations-related information of the vehicle includes a condition of an engine of the vehicle.

10. The apparatus of claim 6, wherein the operations-related information includes a turn signal indication.

11. The apparatus of claim 5, further comprising:

a position sensor for determining a degree of rotation of the steering wheel; and

multiple indicators spaced along a circumference of the steering wheel, wherein the received operations-related information is selectively displayed among the multiple indicators in response to the degree of rotation.

12. The apparatus of claim 11, wherein the received operations-related information is displayed among the multiple indicators so that the displayed operations-related information maintains substantially the same angular position with respect to a driver of the vehicle as the steering wheel is rotated.

13. The apparatus of claim 11, wherein the position sensor comprises a gravity switch.

14. The apparatus of claim 11, wherein the position sensor comprises a rotation detector coupled to a shaft of the steering wheel.

15. The apparatus of claim 11, wherein the position sensor comprises an infrared sensor.

16. The apparatus of claim 11, wherein the position sensor includes an optical sensor.

17. The apparatus of claim 1, further comprising:

a hand sensor for determining the position of the hand on the steering wheel; and

multiple indicators spaced along a circumference of the steering wheel, wherein the indication of the condition is selectively displayed among the multiple indicators in response to the position of the hand on the steering wheel.

18. The apparatus of claim 17, wherein the hand sensor includes a capacitive sensor coupled to a circumference of the steering wheel.

19. The apparatus of claim 17, wherein the hand sensor includes a pressure sensor coupled to a circumference of the steering wheel.

20. The apparatus of claim 17, wherein the hand sensor includes an infrared sensor.

21. The apparatus of claim 17, wherein the hand sensor includes an optical sensor.

22. The apparatus of claim 1, wherein the input stage for receiving the input signal comprising:

a transmission stage for receiving the input signal from a central control system;

a processing unit for processing the received input signal; and

a memory for storing the processed input signal.

23. A method for displaying information to a driver of a vehicle, the method comprising:

receiving an input signal about a condition;

processing the received input signal; and

displaying the processed input signal by using an indicator on a steering wheel of the vehicle.

24. The method of claim 23 further comprising:

determining a parameter of a condition of the steering wheel; and

modifying a display of the processed input signal in response to the determined parameter.

25. The method of claim 24, wherein determining the parameter includes determining a degree of rotation of the steering wheel.

26. The method of claim 24, wherein determining the parameter on the steering wheel includes determining a position of a hand on the steering wheel.
