Abstract:
1. A power output apparatus that outputs power to a driveshaft, the power output apparatus comprising: an internal combustion engine; an electric power-mechanical power input output structure that is connected to an output shaft of the internal combustion engine and to the driveshaft and outputs at least part of output power of the internal combustion engine to the driveshaft through input and output of electric power and mechanical power; a motor that inputs and outputs power; a transmission mechanism that transmits power between a rotating shaft of the motor and the driveshaft with a changeover of a change gear ratio; an accumulator unit that inputs and outputs electric power from and to the electric power-mechanical power input output structure and the motor; a power demand setting module that sets a power demand to be output to the driveshaft; and a control module that attains the changeover of the change gear ratio of the transmission mechanism with corrective change of the output power of the motor,
