Abstract:
1. An eco-drive assist apparatus that displays a quantity of eco-drive that indicates a degree of ecology or economy in driving in a hybrid vehicle equipped with an engine and a motor, comprising: 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 to cause the quantity of eco-drive to be displayed in a graphic manner as a relative quantity to an engine startup threshold value that indicates whether the engine is started up, the second part controlling a display of the quantity of eco-drive in the graphic manner as the relative quantity to the engine startup threshold value on the basis of a first display change threshold value that changes the display from a first display showing that the engine has not been started up to a second display showing that the engine has been started up and a second display change threshold value that changes the display from the second display to the first display, the first display change threshold value being the engine startup threshold value the degree of eco-drive obtained at the first display change threshold value is worse than that at the second display change threshold value, and the second part controls the display so that the quantity of eco-drive is located on a boundary of the engine startup threshold value when the engine has not been started up, when the quantity of eco-drive reaches the second display change threshold value and when the quantity of eco-drive goes beyond the second display change threshold value.
