Abstract:
A powertrain includes an electromechanical transmission operative to transmit torque between an input member and an electric machine and an output member to transmit tractive torque. The electric machine is electrically connected to an inverter device which is electrically connected to an energy storage device. A method for operating the powertrain includes detecting a shutdown event, commanding the transmission to neutral, commanding the electric machine to cease operating in a torque generating mode, and electrically disconnecting the energy storage device from the inverter device.
