Beschreibung
Zusammenfassung:	A method can be used for determining fuel consumption of an internal combustion engine of a vehicle, in real time. The method includes determining a fuel injection quantity of the internal combustion engine based on an oxygen concentration signal from an oxygen sensor and a MAF signal from a mass airflow (MAF) sensor. The MAF sensor is coupled to the intake line and is configured to measure and monitor the mass flow rate of intake air flowing through the intake line. The method further includes determining, via an engine control module (ECM), an instantaneous fuel flow of the internal combustion engine based on the fuel injection quantity. The method further includes communicating, via the ECM, the instantaneous fuel flow to a body control module (BCM) and determining, via the BCM, an average fuel economy of the internal combustion engine based on the fuel flow.
