摘要
A power output device is provided with an internal combustion engine having an output shaft, an electric motor for generating and receiving electric power and for rotating a rotation shaft, a drive shaft mechanically connected to the output and the rotation shaft, and a battery for supplying electric power to the electric motor and storing electric power from the electric motor. When a vehicle mounting the power output device drives normally, a target torque of the motor is determined by the PI (Proportional Integral) control. When the vehicle drives with the engine stopping or idling, however, a target torque is determined to be substantially zero. Then an electric power for the control of the electric motor is prevented from being consumed. While such a control is executed, a target torque of the electric motor is determined by the PI control when the drive shaft is locked. Consequently, even when the drive shaft is locked, the rotation speed of the engine is kept to be substantially constant. Then such problems as a resonance and etc. of the power output device can be avoided and the vehicle drives stably.
