ABSTRACT:
A method and system for calculating the effective fuel economy of a fuel-consuming engine in a vehicle are disclosed. The effective fuel economy is calculated taking into consideration the chemical energy contained in the fuel and the change in kinetic energy of the vehicle (42). The effective fuel economy is also calculated by further considering the change in potential energy of the vehicle (60). The chemical energy contained in the fuel is determined by sensing the mass flow rate of fuel (52). The kinetic energy (56) is determined by sensing the change in the speed of the vehicle and the mass of the vehicle (50). The potential energy (58) is determined by sensing the change in elevation of the vehicle (50). The effective fuel economy is displayed to the operator of the vehicle (64).
