Abstract: A propulsion system includes an electric motor assembly having an electric motor, a driveshaft, and a disconnect clutch. The disconnect clutch is structured to couple the driveshaft to an engine output shaft. The propulsion system further includes a fluid system having a cooling and lubrication fluid circuit fluidly connected to a first pump, and a clutch actuation fluid circuit fluidly connected to a second pump. The cooling and lubrication fluid circuit is fluidly connected to the clutch actuation fluid circuit via at least one of respective pump outgoing conduits from the first pump and the second pump or respective pump supply conduits to the first pump and the second pump. Related operating methodology is also disclosed.
