Abstract

Disclosed embodiments provide a technical improvement for providing visualization of vehicle speed via a speedometer in an instrument cluster of a vehicle/driver interface of a transportation vehicle by providing multiple indicia of vehicle speed and rate of change of speed in a manner that connotes vehicle motion so as to enhance the driving experience for the driver and improve safety.

First claim

The invention claimed is:

1. A speedometer for a transportation vehicle, the speedometer comprising:
a display that includes at least one rotating wheel that is controlled to rotate relative to a stationary portion of the display to depict rotation of the at least one rotating wheel by relative displacement of an edge of the at least one wheel relative to the stationary portion of the display; and
a processor configured to control the rotation of the at least one rotating wheel relative to a fixed point in the stationary portion of the display to indicate a speed of the transportation vehicle, wherein a rate of rotation of the wheel is based on a rate of acceleration of the speed of the transportation vehicle,
wherein the display further comprises a plurality of shapes positioned adjacent to the at least one wheel that move continuously relative to the at least one wheel to convey a sense of movement.

2. The speedometer of claim 1 , wherein the at least one rotating wheel rotates relative to a fixed point so as to display indicia of a speed and acceleration of the transportation vehicle.

3. The speedometer of claim 1 , wherein the at least one rotating wheel rotates so that a current vehicle speed indicia positioned on the at least one rotating wheel aligns on a horizontal rule of the at least one rotating wheel.

4. A user interface for a transportation vehicle, the user interface comprising:
a display that includes at least one wheel that is controlled to rotate relative to a stationary portion of the display to depict rotation of the at least one wheel by relative displacement of an edge of the at least one wheel,
wherein the at least one wheel appears to rotate relative to a fixed point in the stationary portion of the display to convey movement and indicate a speed of the transportation vehicle,
wherein a rate of rotation of the wheel is based on a rate of acceleration of the speed of the transportation vehicle, and
wherein the display further comprises a plurality of shapes positioned adjacent to the at least one wheel that move continuously relative to the at least one wheel to convey a sense of movement.

5. The user interface of claim 4 , wherein the at least one wheel rotates relative to the fixed point so as to display indicia of a speed and acceleration of the transportation vehicle.

6. The user interface of claim 4 , wherein the at least one wheel rotates in a first direction as the vehicle speed increases.

7. The user interface of claim 4 , wherein the at least one rotating wheel rotates so that a current vehicle speed indicia positioned on the at least one rotating wheel aligns on a horizontal rule of the at least one rotating wheel.

8. The user interface of claim 4 , wherein the user interface further comprises a numerical value of the speed of the transportation vehicle.

9. The user interface of claim 4 , wherein the at least one wheel includes a plurality of markers positioned around a circumference of the at least one wheel and indicating vehicle speed.

10. The user interface of claim 1 , wherein a speed of movement of the plurality of shapes increases with acceleration.

11. The user interface of claim 4 , a shape of the at least one wheel is altered based on a force per unit mass produced by acceleration of the transportation vehicle.

12. The user interface of claim 11 , wherein the alteration of the shape of the at least one wheel deforms the wheels proportionally based on the force per unit mass.

13. The user interface of claim 4 , wherein the at least one wheel may include graphics including variable shading, wherein the shading varies based on transportation speed associated with a position of the graphics on the at least one wheel.

14. The user interface of claim 4 , wherein the user interface includes at least two wheels including a first wheel and a second wheel, wherein the first wheel includes a plurality of markers positioned around a circumference of the first wheel and indicating vehicle speed in miles per hour and the second wheel includes a plurality of markers positioned around a circumference of the second wheel and indicating vehicle speed in kilometers per hour.

15. The user interface of claim 14 , wherein the first and second wheels rotate together relative to respective fixed points so as to display indicia of a speed and acceleration of the transportation vehicle.

16. The user interface of claim 14 , a shape of the first and second wheels is altered based on a force per unit mass produced by acceleration of the transportation vehicle.

17. The user interface of claim 16 , wherein the alteration of the shape of the first and second wheels deforms the wheels proportionally based on the force per unit mass.

18. The user interface of claim 4 , wherein the user interface includes at least two wheels including a first wheel and a second wheel, wherein the first wheel is an outer wheel and the second wheel is an inner wheel.

19. The user interface of claim 18 , wherein the outer wheel includes markers around the circumference of the outer wheel in ascending order to indicate vehicle speed.
