Abstract

A system and method for determining fuel consumption and travel range of an electric hybrid vehicle, such as an electric hybrid fuel cell vehicle. The method includes converting the output current of a battery to a virtual consumed fuel consumption flow value and then adding the virtual consumed fuel consumption flow value to an actual consumed fuel value to get a total consumed fuel value that is then divided by the travelled distance of the vehicle to get the fuel consumption of the vehicle. The method also includes converting the SOC of the battery to a virtual available fuel value and then adding the virtual available fuel value to an actual available fuel value to get a total available fuel value that is then divided by the fuel consumption to get the travel range of the vehicle.
