Abstract
A power output apparatus (20) of the present invention includes a clutch motor (30), an assist motor (40), and a controller (80) for controlling the clutch motor (30) and the assist motor (40). The clutch motor (30) includes an outer rotor (32) linked with a crankshaft (56) of a gasoline engine (50) and an inner rotor (34) connecting with a drive shaft (22). The assist motor (40) includes a rotor (42) connecting with the drive shaft (22). A control CPU (90) of the controller (80) controls a first driving circuit (91) to enable the clutch motor (30) to carry out the regenerative operation. The clutch motor (30) accordingly regenerates energy corresponding to a slip between the outer rotor (32) and the inner rotor (34) as electric power. The control CPU (90) then controls a second driving circuit (92) to enable the assist motor (40) to carry out the power operation with the electric power regenerated by the clutch motor (30), thereby rotating the drive shaft (22) in the reverse of the rotation of the crankshaft (56). The power output apparatus (20) of the invention thus constructed can transmit or utilize the power generated by the gasoline engine (50) at a high efficiency and enable the drive shaft (22) to rotate in the reverse of the rotation of the crankshaft (56).
