FUEL ECONOMY EVALUATION DEVICE AND FUEL ECONOMY EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To more accurately evaluate fuel economy based on universal ideal fuel consumption rate.;SOLUTION: In this fuel economy evaluation device 10a, a fuel consumption rate evaluation process part 11e divides actual fuel consumption rate (liter/km) based on universal fuel consumption rate (liter/km) not depending on drivers by ideal fuel consumption rate (liter/km) calculated based on similarly universal fuel consumption rate (liter/km), multiplies the quotient by 100 to calculate percentage of the actual fuel consumption rate (liter/km) to the ideal fuel consumption rate (liter/km), and evaluates the actual fuel consumption rate (liter/km). A drive of a vehicle 1 can obviously recognize how good economical travel its own drive achieves. Since fuel economy can be evaluated with universal unified standard regardless with types of vehicles, fuel economy can be compared among different vehicle kinds and among different drivers.;COPYRIGHT: (C)2009,JPO&INPIT
