Abstract

See full text

A plug-in hybrid powertrain for automotive vehicle is provided which has an internal combustion engine; an electric machine; multiple planetary gear sets, multiple selectively engageable clutch mechanisms and an output member. Selectively engaging those clutches will achieve multiple operation modes including multiple torque transfer ratio from electric machine to output member; multiple torque transfer ratio from internal combustion engine to output member; electric machine propulsion mode; internal combustion engine propulsion mode; generator assistant vehicle launch modes for forward and reverse in the internal combustion engine vehicle launch operations; motor assistant propulsion when in internal combustion engine vehicle propulsion operations; and engine cranking mode. The plug-in hybrid powertrain achieves more torque transfer ratios and operational mode with given number of planetary gear sets and clutches then any existing system.
