Abstract

A power output apparatus 20 includes an engine 50, a clutch motor 30 having rotors 31 and 33 respectively linked with a crankshaft 56 and a drive shaft 22, an assist motor 40 attached to a rotor-rotating shaft 38, a first clutch 45 for connecting and disconnecting the rotor-rotating shaft 38 to and from the crankshaft 56, a second clutch 46 for connecting and disconnecting the rotor-rotating shaft 38 to and from the drive shaft 22, and a controller 80 for controlling the motors 30 and 40. The controller 80 operates the clutches 45 and 46 according to the states of the engine 50 and the drive shaft 22 and changes the connection of the rotor-rotating shaft 38, so as to enable power output from the engine 50 to be efficiently converted by the motors 30 and 40 and output to the drive shaft 22.
