ABSTRACT:
A power output apparatus (20) of the present invention includes an engine (50), a clutch motor (30) connecting with a crankshaft (56) of the engine (50), an assist motor (40) connecting with a drive shaft (22), and a controller (80) for controlling the clutch motor (30) and the assist motor (40). In order to attain stable driving of the engine (50) at a target engine torque and a target engine speed, the engine (50) is feedback controlled with the torque of the clutch motor (30). In the feedback control, a range of scatter of the revolving speed of the crankshaft (56) (that is, a variation in rotation or pulsating torque) due to the pulsating power output from the engine (50) is set as a dead zone. The torque of the clutch motor (30) is accordingly not varied with the variation in rotation of the crankshaft 56 (pulsating torque). This structure effectively prevents the variation in rotation (pulsating torque) from being transmitted to the drive shaft (22).
