Abstract
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.
