1. A power output apparatus that outputs power to a drive shaft, said power output apparatus comprising:

  • an internal combustion engine;

    an electric power-mechanical power input-output module that is connected to an output shaft of the internal combustion engine and to the drive shaft and outputs at least part of output power from the internal combustion engine to the drive shaft through input and output of electric power and mechanical power;

    a motor that inputs and outputs power from and to the drive shaft;

    a target drive point setting module that sets a target drive point of the internal combustion engine, based on a power demand required to the drive shaft;

    an output decrease detection module that detects an output decreasing state, where the output power from the internal combustion engine is lower than a power level defined by the target drive point, while the internal combustion engine is under a preset control to be driven at the target drive point; and

    a control module that controls the internal combustion engine, said electric power-mechanical power input-output module, and the motor with a predetermined control parameter, in the case of no detection of the output decreasing state by said output decrease detection module, said control module correcting the predetermined control parameter to increase the output power from the internal combustion engine, in the case of detection of the output decreasing state by said output decrease detection module, and controlling the internal combustion engine, said electric power-mechanical power input-output module, and the motor with the corrected control parameter.
