Eco-drive assist apparatus and method

摘要

An eco-drive assist apparatus that 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, 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 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 controls 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 is the engine startup threshold value.
