Patent Images
1. On a computing device, a method for predicting fuel usage for a vehicle, the method comprising:
- obtaining map information for a trip having a route;
obtaining road characteristic information for the route from the map information, the road characteristic information defining road features for the route;
obtaining a plurality of trip features from the map information and road characteristic information, the plurality of trip features comprising effects of the road features on a vehicle traveling the route;
obtaining vehicle-specific parameters for the vehicle;
determining a predicted fuel usage for the trip from the vehicle-specific parameters and the plurality of trip features; and
outputting the predicted fuel usage.

Abstract
Examples are disclosed herein that relate to estimating and predicting vehicular fuel use. One example estimates fuel usage by a vehicle during a trip by obtaining sensor measurements from one or more sensors of a mobile computing device during the trip, determining a plurality of trip features from the sensor measurements, each trip feature representing an aspect of one or more of energy produced and energy consumed during the trip, obtaining vehicle-specific parameters of the vehicle, and determining an estimated fuel usage from the vehicle-specific parameters and the plurality of trip features for output by the computing device.
