Abstract
The present invention provides a vehicle display device which can display fuel consumption information of a vehicle in a useful and optimum mode for a driver. A meter_EUC calculates an instantaneous fuel consumption of a vehicle based on a mileage and a fuel injection quantity within a set time, calculates an average fuel consumption of the vehicle based on respective cumulative values of the mileage and the fuel injection quantity repeatedly calculated for every set time, and displays the deviation of the instantaneous fuel consumption with respect to the average fuel consumption as fuel consumption information on a fuel consumption meter. The display on the fuel consumption meter is performed by swinging a pointer with respect to a neutral position. When the deviation takes a positive value, the pointer is swung in the pulse direction with a swinging width corresponding to the deviation quantity, while when the deviation takes a negative value, the pointer is swung in the minus direction with a swinging width corresponding to the deviation quantity.
