Abstract

A multi-functional, composite fuel display for displaying both fuel level information and fuel economy information is provided. The fuel level is displayed using a plurality of bar segments, each corresponding to a single unit of fuel. Once a single unit of fuel is consumed, the corresponding bar segment changes size to indicate an average fuel economy for that unit of fuel. The bar segment corresponding to the current unit of fuel being consumed changes size in real time to indicate instantaneous fuel economy. An indicator is provided over the bar segments corresponding to single unit of consumed fuel to indicate average fuel economy for the current tank of fuel.

Claims

1. A fuel gauge comprising:

a plurality of bar segments that collectively correspond to a single tank of fuel, each individual bar segment corresponding to a single unit of fuel and having a fuel consumed state and a fuel remaining state, wherein each bar segment in the fuel consumed state is sized according to an average fuel economy value for the unit of fuel to which it corresponds.

2. The fuel gauge of claim 1, wherein the bar segment associated with a current unit of fuel being consumed is displayed in the fuel remaining state.

3. The fuel gauge of claim 2, wherein the bar segment associated with the current unit of fuel being consumed is sized according to an instantaneous fuel economy value.

4. The fuel gauge of claim 1, further comprising a fuel economy indicator corresponding to a fuel economy value.

5. The fuel gauge of claim 4, wherein the fuel economy indicator is an average fuel economy indicator corresponding to an average fuel economy value for a current tank of fuel.

6. The fuel gauge of claim 4, wherein the fuel economy indicator is an average fuel economy indicator corresponding to a trip average fuel economy value.

7. The fuel gauge of claim 4, wherein the fuel economy indicator is an overall fuel economy indicator.

8. The fuel gauge of claim 4, wherein the fuel economy indicator is a numerical fuel economy readout for displaying the fuel economy value.

9. A digital fuel gauge comprising:

a plurality of discrete bar segments that collectively represent a capacity of a fuel tank, each individual bar segment representing an equal unit of fuel and is displayed in one of only two display states, a fuel consumed state and a fuel remaining state, wherein each bar segment changes size based on an average fuel economy value for the unit of fuel to which it corresponds upon transitioning from the fuel remaining state to the fuel consumed state.

10. The fuel gauge of claim 9, wherein the bar segment associated with a current unit of fuel being consumed is displayed in the fuel remaining state.

11. The fuel gauge of claim 10, wherein the bar segment associated with the current unit of fuel being consumed is sized according to an instantaneous fuel economy value.

12. The fuel gauge of claim 9, further comprising a fuel economy indicator corresponding to a fuel economy value.

13. The fuel gauge of claim 12, wherein the fuel economy indicator is an average fuel economy indicator corresponding to an average fuel economy value for a current tank of fuel.

14. The fuel gauge of claim 12, wherein the fuel economy indicator is superimposed over at least the bar segments in the fuel consumed state.

15. The fuel gauge of claim 12, wherein the fuel economy indicator is an average fuel economy indicator corresponding to a trip average fuel economy value.

16. The fuel gauge of claim 12, wherein the fuel economy indicator is an overall fuel economy indicator.

17. The fuel gauge of claim 12, wherein the fuel economy indicator is a numerical fuel economy readout for displaying the fuel economy value.

18. A fuel gauge comprising:

a plurality of bar segments that collectively correspond to a single tank of fuel, each individual bar segment corresponding to a single unit of fuel and having either a fuel consumed state or a fuel remaining state, each bar segment in the fuel consumed state is sized according to an average fuel economy value for the unit of fuel to which it corresponds; and

a fuel economy indicator superimposed over at least the bar segments in the fuel consumed state, the fuel economy indicator corresponding to a fuel economy value.
