Abstract

A method for providing in-vehicle fuel-related information is disclosed. A geographic location of a vehicle is determined. A driving distance remaining for the vehicle is estimated based on a current fuel level and a fuel consumption rate of the vehicle. Fuel providers are located within a search area of the driving distance remaining for the vehicle, and one or more of the fuel providers are output. A travel cost for the vehicle may also be calculated.

Claims

1. A method for providing in-vehicle fuel-related information, the method comprising:

determining a geographic location of a vehicle;

estimating a driving distance remaining for the vehicle based on a current fuel level and a fuel consumption rate of the vehicle;

locating fuel providers within a search area of the driving distance remaining for the vehicle; and

outputting one or more of the fuel providers.

2. The method of claim 1, wherein the search area is determined by:

comparing the driving distance remaining for the vehicle with a search distance threshold; and

setting the search area to the lesser of the driving distance remaining for the vehicle and the search distance threshold.

3. The method of claim 1, further comprising receiving a user preference for optimum time, wherein the search area is constrained based upon a direction of travel of the vehicle such that fuel providers closer to the direction of travel are preferred over fuel providers in an opposite direction of travel.

4. The method of claim 1, further comprising receiving a user preference for optimum time and a vehicle destination, wherein the search area is constrained based upon a route of travel to the vehicle destination such that fuel providers closer to the route of travel are preferred over fuel providers further from the route of travel.

5. The method of claim 1, further comprising receiving a fuel price per unit of measure for a fuel type compatible with the vehicle from the fuel providers within the search area and ranking the fuel providers from lowest to highest fuel price per unit of measure.

6. The method of claim 5, wherein the ranking of the fuel providers within the search area is furthered adjusted favoring previously selected fuel providers.

7. The method of claim 5, wherein the ranking of the fuel providers within the search area is further adjusted favoring fuel providers in closer geographic proximity to the vehicle.

8. The method of claim 5, wherein the outputting includes the fuel providers within the search area and their associated rankings.

9. The method of claim 1, further comprising:

receiving a fuel price per unit of measure for one fuel type compatible with the vehicle from the fuel providers within the search area;

if the vehicle is compatible with two or more fuel types then for each fuel price per unit of measure received normalizing the fuel price per unit as a price per unit of distance; and

ranking the fuel providers from lowest to highest fuel price per unit of distance.

10. The method of claim 1, further comprising initiating generation of in-vehicle fuel-related information upon a user command, upon the estimated driving distance remaining for the vehicle falling below a safety margin distance threshold value, or upon the fuel level falling below a fuel level threshold value.

11. An apparatus for providing in-vehicle fuel-related information, comprising:

a processing circuit responsive to executable instructions which, when executed by the processing circuit;

determines a geographic location of a vehicle;

estimates a driving distance remaining for the vehicle based on a current fuel level and a fuel consumption rate of the vehicle;

locates fuel providers within a search area of the driving distance remaining for the vehicle; and

outputs one or more of the fuel providers.

12. The apparatus of claim 11, wherein the processing circuit determines the search area by:

comparing the driving distance remaining for the vehicle with a search distance threshold; and

setting the search area to the lesser of the driving distance remaining for the vehicle and the search distance threshold.

13. The apparatus of claim 11, wherein the processing circuit further receives a user preference for optimum time, and constrains the search area based upon a direction of travel of the vehicle such that fuel providers closer to the direction of travel are preferred over fuel providers in an opposite direction of travel.

14. The apparatus of claim 11, wherein the processing circuit further receives a user preference for optimum time and a vehicle destination, and constrains the search area based upon a route of travel to the vehicle destination such that fuel providers closer to the route of travel are preferred over fuel providers further from the route of travel.

15. The apparatus of claim 11, wherein the processing circuit further receives a fuel price per unit of measure for a fuel type compatible with the vehicle from the fuel providers within the search area and ranks the fuel providers from lowest to highest fuel price per unit of measure.

16. The apparatus of claim 15, wherein the processing circuit further adjusts the ranking of the fuel providers within the search area by favoring previously selected fuel providers.

17. The apparatus of claim 15, wherein the processing circuit further adjusts the ranking of the fuel providers within the search area by favoring fuel providers in closer geographic proximity to the vehicle.

18. The apparatus of claim 15, wherein the outputting includes the fuel providers within the search area and their associated rankings.

19. The apparatus of claim 11, wherein the processing circuit further:

receives a fuel price per unit of measure for one fuel type compatible with the vehicle from the fuel providers within the search area;

if the vehicle is compatible with two or more fuel types then for each fuel price per unit of measure received normalizes the fuel price per unit as a price per unit of distance; and

ranks the fuel providers from lowest to highest fuel price per unit of distance.

20. A method for providing in-vehicle fuel related information, the method comprising:

initiating a travel cost calculation;

determining an initial amount of fuel available in a vehicle prior to an additional amount of fuel being added;

determining the cost of the initial amount of fuel, comprising;

receiving information about the cost-per-unit-of-measure of the initial amount of fuel, and multiplying this cost-per-unit-of-measure by the initial amount;

sensing an additional amount of fuel being added to the vehicle, determining the amount of fuel added, and determining the total amount of fuel available from the initial amount and the amount added;

determining the cost of the additional amount of fuel, comprising;

receiving from a provider of the additional amount of fuel the provider'"'"'s cost-per-unit-of-measure, and multiplying the provider'"'"'s cost-per-unit-of-measure by the additional amount;

determining the average monetary value of the total amount of fuel, comprising;

adding the cost of the initial amount of fuel to the cost of the additional amount of fuel to determine a total cost of the total amount of fuel, and dividing the total cost by the total amount of fuel to determine the average-cost-per-unit-of-measure of the total amount of fuel available;

providing to a user of the vehicle the average monetary value of the total amount of fuel available, comprising;

providing to a user of the vehicle the average-cost-per-unit-of-measure of the total amount of fuel available, the total cost of the total amount of fuel available, or both; and

concluding the travel cost calculation, and in response thereto, determining the amount of fuel consumed since the initiating step, and calculating the cost of the fuel consumed by multiplying the amount of fuel consumed by the average monetary value of the total amount of fuel available, the average monetary value being provided as a per-unit-of-measure value.
