Vehicle display device
First Claim
1. A vehicle-use 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 the cumulative value of the fuel injection quantity;
a display unit for having a pointer type meter for displaying the deviation of the instantaneous fuel consumption with respect to the average fuel consumption as the fuel consumption information based on swinging of a pointer with respect to a neutral position; and
the display control unit for controlling said display unit so as to display the fuel consumption information by swinging the pointer in the plus direction set on one side of the neutral position with a swinging width corresponding to the deviation quantity when the deviation takes a positive value, and swinging the pointer in the minus direction set on another side of the neutral position with a swinging width corresponding to the deviation quantity when the deviation takes a negative value.

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.
