Patent Images
1. A method for calculating the mileage range for a vehicle having a fuel tank, the method comprising:
- obtaining a current fuel parameter value corresponding to fuel in the fuel tank after a refueling event;
obtaining a past fuel parameter value corresponding to fuel in the fuel tank prior to the refueling event;
calculating a scale factor based on the current fuel parameter value and the past fuel parameter value;
scaling a past fuel consumption value using the scale factor to obtain an adjusted fuel consumption value; and
generating an updated mileage range value based on the adjusted fuel consumption value.

Abstract
A flex fuel vehicle mileage range calculating system and method as described herein can effectively be utilized to calculate the mileage range value corresponding to a fuel mixture. The system is suitable for use in all vehicles capable of using various fuel mixtures. The system can calculate a scale factor, update the mileage range value based on the scale factor and, display the updated mileage range value on an on-board display element to correspond to the fuel mixture in the fuel tank.
