Abstract
An FI/AT/MGECU in a control unit calculates an EV travel capable battery terminal discharge power which is the dischargeable power from a battery during EV travel which is travel under the driving force from the motor, according to a state of charge of the battery and a vehicle travelling speed. Based on the calculated EV travel capable battery terminal discharge power and a predetermined limit value, an energy management charge-discharge required battery terminal power is calculated. Then an energy management charge-discharge required torque corresponding to the energy management charge-discharge required battery terminal power, that is the motor torque capable of being output, is calculated based on; a predetermined PDU-MOT overall efficiency efima which is the conversion efficiency of the electric power and the motive power between the power drive unit and the motor, a rotation frequency of the motor, and a predetermined torque limit value for protecting the motor.
