Patent ID: 8380376

Claim:
A power output apparatus that outputs power to a drive shaft, comprising: an internal combustion engine; an exhaust gas control apparatus that includes a catalyst for purifying exhaust gas discharged from the internal combustion engine; a first electric motor that inputs and outputs power; a power distributing portion that is connected to three shafts, including an engine shaft of the internal combustion engine, a rotating shaft of the first electric motor, and the drive shaft, and inputs and outputs power that is based on power input and output from and to two of these three shafts, to and from the remaining shaft; a second electric motor that inputs and outputs power from and to the drive shaft; a power storage device that supplies and receives electric power to and from the first electric motor and the second electric motor; a required torque setting portion that sets a required torque that is required at the drive shaft; and a control portion that, when there is a demand to decelerate the drive shaft while a supply of fuel to the internal combustion engine is being prohibited to suppress degradation of the catalyst, controls the internal combustion engine, the first electric motor, and the second electric motor such that torque based on the set required torque is output to the drive shaft and the rotation speed of the internal combustion engine is decreased to a preset self-sustaining rotation speed with the supply of fuel and an intake air adjustment that increases the intake air amount of the internal combustion engine as the temperature of the power storage device increases.
