Abstract:
A hybrid vehicle includes an internal combustion engine, an electrical storage device, a rotary electric machine, and a controller. The hybrid vehicle travels in a selected one of a charge sustaining mode and a charge depleting mode. Switching from the charge depleting mode to the charge sustaining mode is controlled such that a first state of charge is higher than a second state of charge. In the first state of charge, the controller switches from the charge depleting mode to the charge sustaining mode at the time when operation characteristic of the intake valve is unchangeable to a desired operation characteristic. In the second state of charge there is switching from the charge depleting mode to the charge sustaining mode at the time when the operation characteristic of the intake valve is changeable to a desired operation characteristic.
