摘要
PROBLEM TO BE SOLVED: To enable instructions on driving methods for improved fuel economy by analyzing driving ways and providing a numerical evaluation, whereas evalua tion as to whether it is good mileage driving or bad mileage driving is easily made since the mileage can be calculated provided the miles driven and the fuel consumption are obtained, but what driving aspect causes a bad mileage has been unknown.;SOLUTION: Paying attention to the fact that the higher a driving speed is, the worse a mileage becomes, whether driving is fuel-efficient or not is evaluated. Generally, driving ways are different between local street driving and expressway driving. Therefore, whether it is local street driving or expressway driving is determined (steps 1 to 5), and each driving time for each predetermined driving speed range is recorded respectively (steps 6, 7). A time portion of extraordinary driving which is made reluctantly is excluded as a noise portion, and for the other driving time approximate maximum driving speeds are determined to make evaluation with those driving speeds (steps 10, 11).;COPYRIGHT: (C)2003,JPO
