ABSTRACT:
A power output apparatus (20) of the present invention includes a clutch motor (30), an assist motor (40), an engine (50), and a controller (80) for controlling the clutch motor (30) and the assist motor (40). Auxiliary machinery driven by the rotation of a crankshaft (56), such as a cooling pump (104) and a P/S pump (106), are connected directly or via a belt (102) to a crankshaft (56B) of the engine (50). When the assist motor (40) rotates a drive shaft (22) only with electric power stored in a battery (94) under the non-operating condition of the engine (50), the clutch motor (30) applies a torque of rotational motion TST to the crankshaft (56) to rotate the crankshaft (56) at a predetermined revolving speed. This structure allows the crankshaft (56) to be rotated even when the engine (50) is at a stop, thereby supplying the required power to drive the auxiliary machinery.
