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 linked with an output shaft of said internal combustion engine and with said drive shaft and outputs at least part of power from said internal combustion engine to said drive shaft through inputs and outputs of electric power and mechanical power;

    a motor that is capable of inputting and outputting power from and to said drive shaft;

    an accumulator that is capable of supplying and receiving electric power to and from said electric power-mechanical power input-output module and said motor;

    a power demand setting module that sets a power demand required to said drive shaft, in response to an operator'"'"'s manipulation;

    a target power setting module that sets a target power to be output from said internal combustion engine, based on the setting of the power demand;

    a drive restriction effectuation module that, when a predetermined restricting condition is fulfilled, effects a drive restriction of said motor based on the predetermined restricting condition;

    a correction module that corrects the setting of the target power based on the effected drive restriction, when the drive restriction of said motor is effected by said drive restriction effectuation module; and

    a control module that executes normal control of controlling said internal combustion engine, said electric power-mechanical power input-output module, and said motor in the case of no effectuation of the drive restriction of said motor by said drive restriction effectuation module to ensure output of the target power from said internal combustion engine and output of a power corresponding to the setting of the power demand to said drive shaft, said control module executing restriction control of controlling said internal combustion engine, said electric power-mechanical power input-output module, and said motor in the case of effectuation of the drive restriction of said motor by said drive restriction effectuation module to ensure output of the corrected target power from said internal combustion engine and output of a power in a range of the effected drive restriction from said motor.
