Abstract:
1. A powertrain system for a vehicle, the powertrain system comprising: an internal combustion engine; a drivetrain gear for connection to a drivetrain of the vehicle; a gearset connecting the internal combustion engine to the drivetrain gear; a first electric machine comprising a first rotor and a first stator; a first shaft connecting the first electric machine to the gearset, and defining a shaft axis; a second electric machine comprising a second rotor and second stator; and at least one dynamic clutch selectively coupling the second electric machine to the drivetrain gear and the gearset, wherein the first and second electric machines are operable independently as an electric motor and an electric generator, wherein the first rotor and stator are arranged concentrically about the shaft axis, and the second rotor and stator are arranged concentrically about the shaft axis and wherein the at least one dynamic clutch comprises a first dynamic clutch, and, in a compound mode of operation, the first dynamic clutch connects the second electric machine to the first shaft for transferring power from the first and second electric machines to the gearset.
