System and method for measuring and reducing vehicle fuel waste
One way to improve fuel efficiency of a vehicle is to detect the vehicle operational shortcomings related to fuel consumption by determining whether fuel used during operation of the vehicle is normal fuel use or wasted fuel use. Considerations of idling, speeding and inappropriate gear shifts are some ways to measure the amount of fuel wasted due to operator shortcomings. Communicating this information to the operator in real-time so adjustments can be made will improve vehicle fuel efficiency. These techniques are applicable to tracking employment of other driving best practices as well.
1. A method of detecting vehicle operational shortcomings related to fuel consumption, comprising:
determining, from information obtained by a sensor positioned on a vehicle, that fuel used during operation of the vehicle is wasted fuel use;
categorizing the fuel used by the vehicle into one of a plurality of wasted fuel use categories;
recording, on a non-transitory computer readable medium, the categorized fuel use;
determining performance information related to the vehicle from the recorded categorized fuel used by determining a minimum amount of fuel required for a sortie, wherein determining the minimum amount of fuel required for the sortie comprises:
determining a total amount of fuel used for the sortie; and
subtracting a wasted amount of fuel categorized into the plurality of wasted fuel use categories for the sortie from the total amount of fuel used for the sortie; and
presenting the performance information which comprises the amount of fuel wasted.
2. The method of claim 1 , wherein the plurality of wasted fuel use categories comprises at least one idle gear category.
3. The method of claim 1 , wherein the plurality of wasted fuel use categories comprises at least one gear shifting category.
4. The method of claim 1 , wherein the plurality of wasted fuel use categories comprises at least one speed category.
5. The method of claim 1 , wherein the performance information further comprises operator instructions and presenting further comprises communicating the operator instructions to an operator of the vehicle during operation of the vehicle.
6. The method of claim 1 , comprising receiving global positioning satellite signals.
7. The method of claim 1 , wherein the presenting occurs via a display visible to a driver of the vehicle.
8. The method of claim 1 , wherein the wasted fuel use categories comprise vehicle weight, route, terrain, a perfectly-geared vehicle, and speed thresholds.
9. The method of claim 1 , further comprising attributing fuel used during a current time frame as normal fuel use and storing fuel used in a fuel-use log in association with an attributed category.
10. The method of claim 1 , further comprising attributing an amount of fuel used outside an efficient range to a gearing category and recording the attribution in a fuel-use log, based upon engine speed being outside of a fuel-efficient range for a selected gear.
11. A system for detecting vehicle operational shortcomings, comprising:
at least one sensor configured to sense information about operation of a vehicle and positioned on the vehicle;
a data storage device configured to record the sensed information;
a determination module configured to determine, from the sensed information, whether fuel used during operation of the vehicle is wasted fuel use;
a categorization module configured to categorize the fuel used by the vehicle into one of a plurality of wasted fuel use categories; and
an apparatus configured to present performance information comprising an amount of fuel wasted related to the vehicle, wherein the determination module further is configured to determine the performance information from the categorized fuel used by being further configured to determine a minimum amount of fuel required for a sortie, wherein being further configured to determine the minimum amount of fuel required for the sortie further comprises being further configured to:
determine a total amount of fuel used for the sortie; and
subtract the wasted amount of fuel categorized into the plurality of wasted fuel use categories for the sortie from the total amount of fuel used for the sortie.
12. The system of claim 11 , wherein the plurality of wasted fuel use categories comprises at least one idle gear category.
13. The system of claim 11 , wherein the plurality of wasted fuel use categories comprises at least one gear shifting category.
14. The system of claim 11 , wherein the plurality of wasted fuel use categories comprises at least one speed category.
15. The system of claim 11 , wherein the performance information comprises operator instructions and the apparatus is configured to present the operator instructions to an operator of the vehicle during operation of the vehicle.
16. The system of claim 11 , comprising a global positioning satellite receiver.
17. The system of claim 11 , wherein the apparatus comprises a display visible to a driver of the vehicle.
18. The system of claim 11 , wherein the wasted fuel use categories comprise vehicle weight, route, terrain, a perfectly-geared vehicle, and speed thresholds.
19. The system of claim 11 , wherein the determination module is further configured to attribute fuel used during a current time frame as normal fuel use and store fuel used in a fuel-use log in association with an attributed category.
20. The system of claim 11 , wherein the determination module is further configured to attribute an amount of fuel used outside an efficient range to a gearing category and record the attribution in a fuel-use log, based upon engine speed being outside of a fuel-efficient range for a selected gear.
