摘要： Regular torque split planetary gear trains for automotive hybrid powertrains are limited by the fixed ratio of the planetary gear train. A powertrain incorporating a continuously variable transmission using a torque split with variable ratios enables the powertrain to use the ideal operating lines (IOL) of the engine, electric motor and generator along with the high voltage battery charge/discharge paths, depending upon the mode of operation (charge sustain or charge deplete modes) of the hybrid powertrain. A powertrain further equipped with a hybrid supervisory controller that chooses the torque split and path of highest efficiency from engine to wheel, can operate at the best potential overall efficiency point in any mode and also provide torque variability, thereby leading to the best combination of powertrain performance and fuel efficiency. Embodiments of powertrain configurations that can improve the efficiency of hybrid vehicles are discussed herein.

摘要： Regular series-parallel hybrid electric powertrains (powersplit eCVT) are two-motor HEV propulsion systems mated with a planetary gear, and most mild or full parallel hybrid systems are single motor systems with a gearbox or continuously variable transmission (CVT) coupled with an electric machine. Coupling a ball-type continuously variable planetary (CVP), such as a VariGlide ® , with one electric machine enables the creation of a parallel HEV architecture with the CVP functioning as a continuously variable transmission, and the motor providing the functionality of electric assist, starter motor capability, launch assist and regenerative braking. Two motor variants provide series-parallel hybrid electric vehicle (HEV) architectures. Embodiments disclosed herein, coupled with a hybrid supervisory controller that chooses the path of highest efficiency from engine to wheel, leads to the creation of a hybrid powertrain that are capable of operating at the best potential overall efficiency point in any mode and also provide torque variability.
