FUEL EFFICIENCY DISPLAY DEVICE, FUEL EFFICIENCY DISPLAY METHOD, AND FUEL EFFICIENCY DISPLAY PROGRAM |
摘要 |
A fuel efficiency display device includes a past average fuel efficiency (AFE) calculating unit, a present AFE calculating unit, an AFE comparison unit, and a display unit. The past AFE calculating unit calculates AFE from a start time of use of the fuel efficiency display device to a finish time of a last driving operation as a past AFE. The present AFE calculating unit calculates an AFE at constant time intervals or at constant intervals of running distance as a present AFE since a start time of a present driving operation. The AFE comparison unit makes a comparison between the present AFE and the past AFE. The display unit displays a proportion of a number of times that the present AFE is more efficient than the past AFE to a total number of the comparisons between the present AFE and the past AFE. |
