Abstract:
1. A method for tracking fuel economy across a plurality of vehicles in a fleet of vehicles by a computer that is remote from the vehicles, comprising the steps of: (a) receiving fuel information from a radio frequency (RF) interrogator corresponding to a quantity of fuel pumped into a first vehicle; (b) receiving a current odometer reading from the RF interrogator corresponding to a current reading for an odometer associated with the first vehicle; (c) determining a previous odometer reading received for the odometer associated with the first vehicle, the previous odometer reading corresponding to a previous fueling of the first vehicle; (d) calculating a distance traveled by the first vehicle since the previous fueling as the difference between the previous odometer reading and the current odometer reading; (e) calculating a fuel economy for the first vehicle as the ratio of the distance traveled and quantity of fuel pumped into the first vehicle; (f) recording the fuel economy and current odometer reading for the first vehicle; and (g) repeating the steps of (a) through (f) for the first vehicle and a plurality of other vehicles of the fleet of vehicles.
