Abstract

A novel graphical display apparatus (and methods) for motor vehicles. The apparatus has a display coupled to an interior portion of a motor vehicle and facing a driver of the motor vehicle. The display is coupled to an output for identifying a revolution per minute (RPM) value of an engine of the motor vehicle. The display has a first graphical display portion of the display for outputting a current gear indication of a current gear. The current gear is one of a plurality of gears in the motor vehicle. A second graphical display portion of the display for outputting one or more indication(s) of a past gear is coupled to the first portion of the display. The past gear is one of the plurality of gears in the motor vehicle that is used before the current gear. A third graphical display portion is also coupled to the display. The third display portion outputs an RPM value indication that corresponds to a current RPM value of the engine of the motor vehicle. The RPM value indication is coupled to the output.

Claims

1. A three-dimensional graphical display apparatus for motor vehicles, the display comprising:

a display coupled to an interior portion of a motor vehicle and facing a driver of the motor vehicle, the display being coupled to an output for identifying a revolution per minute (RPM) value of an engine of the motor vehicle;

a first graphical display portion of the display for outputting a current gear indication of a current gear, the current gear being one of a plurality of gears in the motor vehicle being engaged by the motor vehicle;

a second graphical display portion of the display for outputting one or more indications of a past gear, the past gear being one of the plurality of gears in the motor vehicle that was engaged before the current gear and is disengaged by the motor vehicle, the second graphical display portion being coupled to the first graphical display portion; and

a third graphical display portion of the display for outputting an RPM value indication that corresponds to a current RPM value of the engine of the motor vehicle, the RPM value indication being coupled to the output,

wherein the current gear indication and the one or more indications of the past gear are displayed simultaneously.

2. The graphical display of claim 1 wherein the third graphical display portion is coupled to the first graphical display portion.

3. The graphical display of claim 1 wherein the current gear indication is larger in size than the one or more indications of the past gear.

4. The graphical display of claim 1 wherein the display is selected from a CRT, a flat panel display, an active matrix display, or a plasma display.

5. The graphical display of claim 1 wherein the motor vehicle is an automobile.

6. The graphical display of claim 1 wherein the one or more indications of the past gear changes from a larger current gear indication to one or more of the past gear indications.

7. The graphical display of claim 1 wherein the current gear indication and the one or more indications of the past gear form a continuous annular structure in more than one spatial dimension.

8. The graphical display of claim 1 wherein the RPM value indication comprises a range of RPM values from zero to greater than seven thousand.

9. The graphical display of claim 1 wherein the RPM value indication is provided as a single indication in a continuous annular structure in more than one dimension.

10. The graphical display of claim 1 wherein the current gear indication, the one or more indications of the past gear, and the RPM value indication are simultaneously outputted on the display.

11. A method for displaying engine characteristics, the method comprising:

receiving a gear information from an interface coupled to an engine of an operating motor vehicle, the gear information corresponding to only one of a plurality of gears numbered from 1 to N, where N is an integer greater than 1, the gear information corresponding to the gear number used by the operating motor vehicle at a present time of receiving the gear information;

converting the gear information into a gear display format;

displaying a gear indication based upon the gear display format on a display, the gear indication being selected from 1 to N based upon the gear information being used by the operating motor vehicle;

revolving the gear indication about an axis; and

repeating the steps of displaying and revolving for other gears whereupon a current gear indication and a past gear indication are displayed simultaneously where the current gear indication and the past gear indication are among the 1 to N.

12. The method of claim 11 wherein N is an integer greater than six or ten.

13. The method of claim 11 further comprising outputting a past gear indication based upon the gear indication for the gear number used by the operating motor vehicle at the present time that is a past in time of receiving the gear information.

14. The method of claim 13 wherein the past gear indication is displayed simultaneously with the gear indication of the present time.

15. The method of claim 14 wherein the past gear indication is smaller in size to the gear indication.

16. The method of claim 11 further comprising outputting an RPM value indication that corresponds to a current RPM value of the engine of the operating motor vehicle.

17. The method of claim 16 wherein the outputting of the RPM value indication occurs simultaneously with the outputting of the gear indication.

18. The method of claim 17 wherein the RPM value indication is coupled to the gear indication.

19. A method for displaying engine characteristics within an interior portion of motor vehicles, the method comprising:

receiving a first gear information from an interface coupled to an engine of an operating motor vehicle, the first gear information corresponding to only one of a plurality of gears numbered from 1 to N, where N is an integer greater than 1, the first gear information corresponding to the first gear number being engaged by an operating motor vehicle at a present time of receiving the first gear information;

converting the first gear information into a gear display format;

displaying a first gear indication based upon the first gear information on a first portion of a display, the first gear indication being selected from 1 to N based upon the first gear information being used by the operating motor vehicle, where N is an integer greater than 1; and

moving the first gear indication from the first portion of the display to a second portion of the display whereupon the first portion of the display appears in front of the second portion of the display in a multi-dimensional graphical format while replacing the first portion of the display with a second gear indication corresponding to a second gear number being engaged while disengaging the first gear number, the second gear number being among the 1 to N but not the first gear number.
