  • Patent number: 8508354
    Abstract: An accelerator-off, fuel-cut traveling determining unit determines whether the number of engine revolutions of a vehicle is equal to or higher than a predetermined value, whether an accelerator opening rate is equal to or lower than a predetermined value, and whether a traveling state is an accelerator-off, fuel-cut traveling state where a quantity of fuel injection to an engine is 0. When it is determined that the traveling state is the accelerator-off, fuel-cut traveling state, the traveling distance adding-up unit adds up accelerator-off, fuel-cut traveling distances. A fuel-saving driving rating unit rates driving by a driver based on each of the added-up values which were added up by the traveling distance adding-up unit. A fuel-saving driving advice generating unit notifies the driver of a fuel-saving driving advice together with a rating result in accordance with the rating result.
