ABSTRACT:
When engine stop control is executed, an ECU estimates input power to a power storage device in accordance with an estimation of power generated by a generator and estimation of total power consumption of circuitry from the generator to the power storage device in the current state of operation. Further, the ECU compares the estimated input power with a tolerable input power to the storage device. When the generated power is excessive, the state of operation of the circuitry is changed such that the total power consumption by the circuitry increases, and then, torque output of the generator is permitted, to attain desired deceleration at the engine stop. Accordingly, in the engine stop control in which stopping force is generated by the power generating operation by the rotating electric machine, excessive charging caused by excessive power input to the power storage device can be prevented.
