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. An information display system comprising:

a fuel gauge including a plurality of bar segments that collectively correspond to a single tank of fuel, each bar segment corresponding to a single unit of fuel and having a fuel consumed state and a fuel remaining state; and

a controller configured to;

determine a number of units of fuel remaining within the single tank of fuel based at least in part upon an amount of fuel consumed; and

transmit the number of units of fuel remaining so that the fuel gauge displays a bar segment for each unit of fuel in the fuel consumed state and the fuel remaining state.

2. The information display system of claim 1, wherein the fuel gauge further includes a fuel economy indicator corresponding to a fuel economy value.

3. The information display system of claim 1, wherein a bar segment displayed in the fuel consumed state is sized to represent an average fuel economy value for the unit of fuel to which the bar segment corresponds.

4. The information display system of claim 1, wherein the bar segment displayed to indicate a single unit of fuel currently being consumed by the vehicle is displayed in the fuel remaining state.

5. The information display system of claim 4, wherein the bar segment displayed to indicate the single unit of fuel currently being consumed by the vehicle further indicates instantaneous fuel economy.

6. The information display system of claim 2, wherein the fuel economy indicator is an average fuel economy indicator corresponding to an average fuel economy value for a current tank of fuel.

7. The information display system of claim 6, wherein the average fuel economy indicator is displayed as a line over at least the bar segments in the fuel consumed state.

8. The information display system of claim 2, wherein the fuel economy indicator is an overall fuel economy indicator.

9. The information display system of claim 8, wherein the overall fuel economy indicator is displayed as a line over at least the bar segments in the fuel consumed state.

10. The information display system of claim 2, wherein the fuel economy indicator is a numerical fuel economy readout for displaying the fuel economy value.

11. A method comprising:

determining an amount of fuel consumed by a vehicle; and

displaying a fuel gauge including a plurality of bar segments that collectively correspond to a single tank of fuel, each bar segment corresponding to a single unit of fuel and having a fuel consumed state and a fuel remaining state based upon the amount of fuel consumed.

12. The method of claim 11, further comprising:

determining an average fuel economy value for each single unit of consumed fuel; and

displaying the bar segment corresponding to each single unit of consumed fuel having a size indicating the corresponding average fuel economy value.

13. The method of claim 11, further comprising:

determining an instantaneous fuel economy value for the vehicle; and

adjusting the size of the bar segment corresponding to the single unit of fuel currently being consumed to indicate the instantaneous fuel economy value.

14. The method of claim 13, further comprising:

displaying the single unit of fuel currently being consumed by the vehicle in the fuel remaining state.

15. The method of claim 11, further comprising:

determining a tank average fuel economy value corresponding to an average fuel economy for the amount of fuel consumed by the vehicle for the current tank of fuel; and

displaying an average fuel economy indicator corresponding to the tank average fuel economy value.

16. The method of claim 15, wherein the average fuel economy indicator is displayed as a line over at least the bar segments in the fuel consumed state.
