Vehicle drivetrain with an electric torque converter

摘要

A powertrain includes an Electric Torque Converter (ETC) assembly interconnecting a primary power source and a transmission. An ETC clutch connects a clutched ETC input from the ETC assembly to an output of the primary power source. A primary transmission clutch connects a clutched input of the transmission to the output of the primary power source. An ETC output from the ETC assembly is directly connected to a fixed input of the transmission. The ETC assembly includes a planetary gearset interconnecting the clutched ETC input and the ETC output of the ETC assembly. An electric motor is coupled to the planetary gearset and configured to provide a torque thereto. The torque may be directed to either the fixed input of the transmission through the ETC output of the ETC assembly, or to the output of the primary power source through the clutched ETC input of the ETC assembly.
