Abstract

At least one of a state and a storage amount of a battery is detected, and a battery output that can be outputted by the battery is calculated on the basis of it. A state of an electric motor is detected, and at least one of electric motor torque and electric motor output that can be outputted from the electric motor and maximal torque of the electric motor are calculated on the basis of it. A state of an engine is detected, and engine starting torque required to start the engine is calculated on the basis of it. An EV range in which the engine is cut off to be capable of driving with only the electric motor is set up on the basis of the calculated battery output, at least one of the calculated electric motor torque and electric motor output, and the calculated engine starting torque.
