One-mode, input-split, parallel, hybrid transmission

A hybrid transmission comprising:

• an input shaft to receive power from an engine;
• an output shaft;
• first and second motor/generators;
• energy storage means for accepting power from, and supplying power to, said first and second motor/generators;
• control means for regulating power flow between said energy storage means and said motor/generators as well as between said first and second motor/generators;
• at least a first planetary gear set;
• said first planetary gear set having an inner gear member and an outer gear member, each of which meshingly engage a plurality of planet gear members;
• said input shaft is operatively connected to said outer gear member of said first planetary gear set;
• a torque transfer device interposed in the operative connection between said input shaft and said outer gear member of said first planetary gear set;
• said output shaft being operatively connected to one of the other of said gear members in said first planetary gear set;
• said first motor/generator is operatively connected to said inner gear member of said first planetary gear set;
• and,
• said second motor/generator being in continuous, operative connection to said output shaft.
