摘要

An accelerator opening determining unit determines whether an accelerator opening achieved through an accelerator operation by a driver of a vehicle exceeds an upper limit value thereof. A travel distance adding-up unit adds up a travel distance within accelerator-opening upper limit value when the accelerator opening is not determined to exceed the upper limit value. When the accelerator opening is determined to exceed the upper limit value, the travel distance adding-up unit adds up a travel distance exceeding accelerator-opening upper limit value. A fuel-saving driving rating unit rates the driving of the driver based on each added-up value added up by the travel distance adding-up unit.
