System and method for measuring and reducing vehicle fuel waste
View Patent ↗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:
sensing information about operation of a vehicle from at least one sensor positioned on the vehicle;
recording, on a non-transitory computer readable medium, the sensed information;
determining, from the information, whether fuel used during operation of the vehicle is normal fuel use or wasted fuel use;
categorizing the fuel used by the vehicle into one of a plurality of normal fuel use categories when the fuel used is determined to be normal fuel use, or into one of a plurality of wasted fuel use categories when the fuel used is determined to be wasted fuel use;
recording, on the non-transitory computer readable medium, the categorized fuel use;
determining performance information related to the vehicle from the recorded categorized fuel used; and
presenting the performance information which comprises an amount of fuel wasted.
2. The method of claim 1 , wherein determining performance information further comprises determining a minimum amount of fuel required for a sortie.
3. The method of claim 2 , 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.
4. The method of claim 1 , wherein the plurality of wasted fuel use categories comprises at least one idle gear category.
5. The method of claim 1 , wherein the plurality of wasted fuel use categories comprises at least one gear shifting category.
6. The method of claim 1 , wherein the plurality of wasted fuel use categories comprises at least one speed category.
7. 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.
8. The method of claim 1 , comprising receiving global positioning satellite signals.
9. The method of claim 1 , wherein the presenting occurs via a display visible to a driver of the vehicle.
10. 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 normal fuel use or wasted fuel use;
a categorization module configured to categorize the fuel used by the vehicle into one of a plurality of normal fuel use categories when the fuel used is determined to be normal fuel use, and into one of a plurality of wasted fuel use categories when the fuel used is determined to be wasted fuel use; and
an apparatus configured to present performance information comprising an amount of fuel wasted related to the vehicle,
the determination module further configured to determine the performance information from the categorized fuel used.
11. The system of claim 10 , wherein the determination module is further configured to determine a minimum amount of fuel required for a sortie as the performance information.
12. The system of claim 11 , wherein the determination module is configured to determine a total amount of fuel used for the sortie and subtract 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 as the minimum amount of fuel required for the sortie.
13. The system of claim 10 , wherein the plurality of wasted fuel use categories comprises at least one idle gear category.
14. The system of claim 10 , wherein the plurality of wasted fuel use categories comprises at least one gear shifting category.
15. The system of claim 10 , wherein the plurality of wasted fuel use categories comprises at least one speed category.
16. The system of claim 10 , 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.
17. The system of claim 10 , comprising a global positioning satellite receiver.
18. The system of claim 10 , wherein the apparatus comprises a display visible to a driver of the vehicle.
