Patent ID: 7917271

Claim:
A vehicle comprising: an accelerator operation amount detection unit for detecting an accelerator operation amount; a vehicle speed detection unit for detecting a vehicle speed; a climbing road traveling determination unit for performing climbing road traveling determination whether the vehicle travels on a predetermined climbing road based on said detected vehicle speed; a traveling state determination unit for determining that a traveling state of the vehicle is a good state that is an energy efficient state when said detected accelerator operation amount is smaller than a first operation amount, determining that the traveling state of the vehicle is a poor state that is an energy inefficient state when said detected accelerator operation amount is equal to or larger than a second operation amount larger than said first operation amount, maintaining a determination result of the previous traveling state of the vehicle while said climbing road traveling determination unit performs the climbing road traveling determination when said detected accelerator operation amount is equal to or larger than said first operation amount and smaller than said second operation amount, determining that the traveling state of the vehicle is the good state when said climbing road traveling determination unit determines that the vehicle travels on said predetermined climbing road when said detected accelerator operation amount is equal to or larger than said first operation amount and smaller than said second operation amount, and determining that the traveling state of the vehicle is the poor state when said climbing road traveling determination unit determines that the vehicle does not travel on said predetermined climbing road when said detected accelerator operation amount is equal to or larger than said first operation amount and smaller than said second operation amount; and a notification unit for notifying an occupant of the determination result by said traveling state determination unit.
