Abstract
A powertrain for a hybrid electric vehicle (HEV) such as a plug-in hybrid electric vehicle (PHEV) includes an engine, a fuel tank, a battery, and a controller. The controller is configured to determine a distance to empty value as a sum of fuel in the fuel tank and a battery equivalent amount of fuel, the sum multiplied by an average fuel economy of the PHEV based on a driving condition of the vehicle.
