Abstract
While a ring gear shaftlinked with a drive shaft rotates, a power output apparatusapplies a torque to a first motor MGattached to a sun gear shaft, thereby abruptly increasing a revolving speed of an engine, to which a fuel injection is stopped. A torque generated by a frictional force of, for example, a piston in the engineand working as a reaction is applied as a braking torque to the ring gear shaftvia a planetary gear. The magnitude of the braking torque depends upon the frictional force of, for example, the piston and can be controlled by regulating the revolving speed of the engineby means of the first motor MG. This control procedure enables the energy consumed by the engineto be output as a braking force to the drive shaft.
