Abstract
A hybrid powertrain incorporates an engine, two motor/generator mechanisms, and a planetary gearset. The planetary gearset has at least one torque-transmitting mechanism, which may be selectively energized to provide a brake on one of the motor/generators thereby reducing the electrical power generation within the hybrid transmission.
