Patent ID: 7987935

Claim:
A power output apparatus for delivering power to a drive shaft, said power output apparatus comprising: an internal combustion engine; an electric power-mechanical power input output mechanism which is connected to said drive shaft and also rotatably connected to an output shaft of said internal combustion engine independently of said drive shaft to input and output power to and from said drive shaft and said output shaft along with the input and output of electric power and mechanical power; an electric motor capable of delivering power to said drive shaft; an accumulator unit capable of sending and receiving electric power to and from said electric power-mechanical power input output mechanism and said electric motor; an exhaust gas purifying housing which is arranged in an exhaust system of said internal combustion engine, and has a purification catalyst section having a purification catalyst for purifying exhaust gas disposed within the housing on an outlet side, a fuel gas adsorbing section having a fuel gas adsorbent for adsorbing fuel gas in exhaust gas disposed within the housing on an inlet side, and a flow switching section for switching from a first flow that allows exhaust gas to flow mainly to said purification catalyst section of the housing to a second flow that allows all exhaust gas to flow to said purification catalyst section via said fuel gas adsorbing section of the same housing and vice versa; a driving power demand setting unit for setting a driving power demand required to said drive shaft; and a control module for controlling said internal combustion engine, said electric power-mechanical power input output mechanism, and said electric motor so that a driving power based on said set driving power demand is delivered to said drive shaft based on a switching state of said flow switching section of said exhaust gas purifying unit, wherein said power output apparatus further comprises an engine rotation speed detecting module for detecting an engine rotation speed, which is a rotation speed of said internal combustion engine, and wherein said control module is a module for setting a target rotation speed and a target torque by correcting said target torque by a correction amount that is larger as said detected engine rotation speed is higher when the switching state of said flow switching section is a state in which exhaust gas is allowed to flow by said second flow.
