1. A vehicle comprising:
- a battery that drives wheels via a motor;
a processor configured to;
break a received route into a plurality of segments;
calculate a route energy consumption rate correction factor (RECF) for a current segment as a function of the following received values;
a RECF of the previous segment, an observed energy consumption rate, an energy consumption estimate for the current segment, and a distance of the current segment.

Abstract
A vehicle includes an electric machine configured to provide torque to vehicle wheels, a battery electrically coupled with and configured to provide electric power to the electric machine, a display configured to signal information to an operator, and a processor. The processor is configured to present a vehicle driving range on the display. The vehicle driving range is based on a known vehicle route including at least one route segment, an estimated energy usage for the route segment, an available battery charge, and stored energy consumption data from previous drive cycles.
