Abstract
A powertrain system for a vehicle is provided, including 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 connected to the gearset, a second electric machine, and at least one dynamic clutch selectively coupling the second electric machine to the drivetrain gear and the gearset. In a compound mode of operation, the at least one dynamic clutch couples the second electric machine and the gearset. In a split mode of operation, the at least one dynamic clutch couples the second electric machine and the drivetrain gear.
