A power output apparatus includes a planetary gear having a planetary carrier, a sun gear, and a ring gear, an engine having a crankshaft linked with the planetary carrier, a first motor attached to the sun gear, and a second motor attached to the ring gear. In response to an engine operation stop instruction, the power output apparatus stops a fuel injection into the engine and controls the first motor, in order to enable a torque acting in reverse of the rotation of the crankshaft to be output to the crankshaft via the planetary gear and a carrier shaft until the revolving speed of the engine becomes close to zero. This structure allows the revolving speed of the engine to quickly approach zero.

[ What is claimed is:] [1.]1. A power output apparatus for outputting power to a drive shaft, said power output apparatus comprising:an engine having an output shaft;a first motor having a rotating shaft and inputting and outputting power to and from said rotating shaft;a second motor inputting and outputting power to and from said drive shaft;a parallel hybrid system having a power channel that directly outputs at least a part of the power of the engine to the drive shaft;fuel stop instruction means for giving an instruction to stop fuel supply to said engine when a condition of stopping operation of said engine is fulfilled; andstop-time control means for applying a torque to said output shaft of said engine and thereby restricting a deceleration of revolving speed of said output shaft to a predetermined range in response to said instruction to stop the fuel supply to said engine, so as to implement a stop-time control for stopping the operation of said engine.
