Disclosed are an automobile fuel performance calculation apparatus and a method thereof. According to the present invention, the automobile fuel performance calculation apparatus comprises a driving distance calculation unit; a real fuel consumption calculation unit; a fuel performance calculation unit which calculates the fuel performance based on the driving distance calculated by the driving distance calculation unit and the amount of real fuel consumption calculated by the real fuel consumption calculation unit; an energy storage variation calculation unit which calculates the variation in vehicular storage energy including at least one of vehicular kinetic energy stored in a vehicle, vehicular potential energy, and vehicular electric energy; and an energy consumption calculation unit which calculates the energy consumption when the vehicular storage energy is stored.; More specifically, the fuel performance calculation unit calculates the storage energy fuel consumption by converting the amount of energy storage variation to the fuel amount consumed in an engine, calculates the storage energy fuel consumption by converting the consumed energy to the fuel amount consumed in the engine, calculates available fuel consumption by subtracting the storage energy fuel consumption from the real fuel consumption, and calculates the fuel performance comparing the available fuel consumption with the driving distance. According to the present invention, the automobile fuel performance calculation apparatus can inform the relation between the driving distance and fuel consumption by applying driving conditions and operation state of an electric device.
Description
technical field [0001] The present invention relates to a vehicle fuel consumption calculating device and method thereof, and more specifically relates to calculating the fuel consumption of a fuel vehicle equipped with an engine that generates power by using the oxidation heat energy of fuel such as gasoline or hydrogen oil, LPG, ethanol, or hydrogen. Technology for consumer efficiency. Background technique [0002] A fuel car basically includes an engine that generates power, a power transmission device that transmits the power generated by the engine to wheels, a power generator connected to the power transmission device, and a battery connected to the power generator. The term "fuel vehicle" used in this specification also includes a hybrid vehicle that oxidizes hydrogen to generate heat. [0003] Engines generate power by generating heat energy from fuel and converting that heat energy into mechanical energy. [0004] The power generator converts mechanical energy sup...
