  • Vehicle that switches between displaying fuel efficiency on a display device and displaying electricity efficiency on the display device based on engine use history when a selected running mode is a charge depleting mode
    Patent number: 9855958
    Abstract: An ECU causes a display device to display fuel efficiency when a recovery mode is selected as an operation mode in which amount-of-stored-power recovery control of making a target value of an amount of charge of a battery higher than in other modes is performed, causes the display device to display fuel efficiency when a CS mode is selected as a running mode in which the amount of charge of the battery is maintained at a prescribed target with an engine operating, and causes switching of display between fuel efficiency and electricity efficiency on the display device based on an indicator of use history of the engine when a CD mode is selected as the running mode in which running using only a motor generator with the engine stopped is given a high priority.
