摘要：
A method of operating a hybrid powertrain including an engine, an electric motor and a high voltage battery includes preventing a fuel flow to the engine when the high voltage battery includes a state of charge at or above a pre-defined upper limit, and driving the engine with torque supplied by the electric motor when the hybrid powertrain is operating in a fuel-off disabled condition to maintain operation of the engine without producing any engine torque.
