Patent ID: 7772970

Claim:
A vehicle display device comprising: an instantaneous fuel consumption calculation unit for calculating an instantaneous fuel consumption of a vehicle based on a mileage and a fuel injection quantity within a preset set time; an average fuel consumption calculation unit for calculating an average fuel consumption of the vehicle based on a cumulative value of the mileage and a cumulative value of the fuel injection quantity; a display unit comprising a pointer type meter for displaying a deviation of the instantaneous fuel consumption with respect to the average fuel consumption as a fuel consumption information based on a swinging of a pointer with respect to a neutral position; and a display control unit for controlling said display unit so as to display the fuel consumption information by swinging the pointer in a plus direction set on one side of the neutral position with a swinging width corresponding to a deviation quantity when the deviation comprises a positive value, and swinging the pointer in a minus direction set on another side of the neutral position with a swinging width corresponding to the deviation quantity when the deviation comprises a negative value, wherein said average fuel consumption calculation unit calculates a value which is obtained by leveling an average fuel consumption which is directly calculated based on the cumulative value of the mileage and the cumulative value of the fuel injection quantity by weighted average calculation by using a past average fuel consumption as a final average fuel consumption, and wherein a weighting coefficient used in the weighted average calculation is a value which changes the deviation between the average fuel consumption and the instantaneous fuel consumption with respect to an accelerator operation of a driver in a preset region of the accelerator operation.
