Patent ID: 8229610

Claim:
An apparatus that evaluates a deceleration running of a vehicle, the deceleration running being a deceleration state of the vehicle having an energy cut-off mechanism that cuts off energy supply to a motor of the vehicle during the deceleration running, the apparatus comprising: a first calculating unit that calculates a first running distance, the first running distance being a distance run by the vehicle while the vehicle is in the deceleration state during a predetermined period, the predetermined period being from a time when a start of the deceleration state of the vehicle is detected to a time when a start of an acceleration state of the vehicle is detected; a second calculating unit that calculates a second running distance, the second running distance being an ideal distance run by the vehicle when the vehicle decelerates at a predetermined ideal deceleration for energy saving while the vehicle is in the deceleration state during the predetermined period, the second running distance is calculated based on: a running speed of the vehicle at the time when the start of the deceleration state of the vehicle is detected; a running speed of the vehicle at the time when the start of an acceleration state of the vehicle is detected; and the predetermined ideal deceleration for energy saving; an evaluating unit that evaluates the deceleration running of the vehicle based on the first running distance and the second running distance; and a notifying unit that notifies a result of evaluation obtained by the evaluating unit.
