POWER OUTPUT APPARATUS AND METHOD OF CONTROLLING THE SAME

摘要

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).
