First Claim
Patent Images
1. A fuel consumption display system for vehicles, comprising:
- an operator a fuel consumption calculator which calculates different kinds of fuel consumption in a common quantitative unit; and
a computer operated display associated with the fuel consumption calculator which simultaneously displays by a common scale factor the different kinds of fuel consumption calculated by the operator on a common chart by difference in one of indication color and indication pattern, wherein the different kinds of fuel consumption are displayed on a bar graph and a single bar of the bar graph displays more than one kind of fuel consumption.

Abstract
A short-term fuel consumption (A) and a longer-term fuel consumption (B) or corrected longer-term fuel consumption (C) are calculated in a common quantitative unit, and comparatively indicated on a display (2), respectively by a bar graph (20) and a level pointer (211) having a graduated scale common thereto, visually aiding a decision by comparison therebetween.

10. A fuel consumption display system for vehicles, comprising:
-
a temporary fuel consumption calculator for calculating a temporary fuel consumption based on a distance traveled and an amount of fuel consumed during a first period of time;
a comparative fuel consumption calculator for calculating a comparative fuel consumption based on a distance traveled and an amount of fuel consumed during a second period of time longer than the first period of time; and
a computer operated display associated with each one of the temporary fuel consumption calculator and the comparative fuel consumption calculator for indicating the temporary fuel consumption and the comparative fuel consumption by a common indication index on a common chart by difference in one of indication color and indication pattern, wherein the temporary fuel consumption and the comparative fuel consumption are displayed on a bar graph and a single bar of the bar graph displays the temporary fuel consumption and the comparative fuel consumption. - View Dependent Claims (11, 12, 13)

14. A fuel consumption display system for vehicles, comprising:
-
a temporary fuel consumption calculator for calculating a temporary fuel consumption based on a distance traveled and an amount of fuel consumed during a prescribed period of time;
a comparative fuel consumption calculator for calculating a comparative fuel consumption based on travel path information to be set; and
a computer operated display associated with each one of the temporary fuel consumption calculator and the comparative fuel consumption calculator for indicating the temporary fuel consumption and the comparative fuel consumption by a common indication index on a common chart by difference in one of indication color and indication pattern, wherein the temporary fuel consumption and the comparative fuel consumption are displayed on a bar graph and a single bar of the bar graph displays the temporary fuel consumption and the comparative fuel consumption.
