An electrically variable transmission having a single motor/generator
provides electrically variable power flow along dual power paths and
provides an electrically variable reverse operating mode. The
transmission includes a compound differential gear set having at least
four gear elements operatively interconnected with one another. A
transmission input member and the single motor/generator selectively
provide power to a transmission output member via the differential gear
set. The transmission includes a plurality of intermeshing gears,
including a reversing gear and gears connected for rotation with the
output member, for operatively connecting the differential gear set with
the output member. Torque-transmitting mechanisms are selectively
engagable to provide power flow between the input member and the output
member in multiple operating modes, including a parallel hybrid
electrically variable reverse operating mode utilizing the reversing
gear. A method of operating a transmission that allows shifting between
different gearing portions of the transmission is provided.
