Eco-drive assist apparatus and method |
摘要 |
An eco-drive assist apparatus displays a quantity of eco-drive that indicates a degree of ecology and/or economy in driving in a hybrid vehicle equipped with an engine and a motor. The apparatus includes a first part configured to calculate the quantity of eco-drive on the basis of a vehicle power generated in the vehicle, and a second part configured to cause the quantity of eco-drive to be displayed in a graphic manner as a relative quantity to an eco-drive judgment threshold value that indicates whether the vehicle is in an eco-drive state and as a relative quantity to an engine startup threshold value that indicates whether the engine has been started up and configured to cause the quantity of eco-drive to be displayed on a boundary of the engine startup threshold value or displayed at a position where the quantity of eco-drive is worse than the engine startup threshold value when the engine has been started up. The second part causes the quantity of eco-drive to be displayed at a position where the quantity of eco-drive is better than the engine startup threshold value when the engine has been started up and a driver's operation needs no vehicle power. |
