Abstract

See full text

A method of operating a hybrid powertrain including an engine, an electric motor and a high voltage battery includes preventing fuel flow to the engine when the high voltage battery includes a state of charge at or above a pre-defined upper limit, and when the hybrid powertrain is operating in a second fueling condition in which fuel flow to the engine is preferably maintained. The engine is rotated with torque supplied by the electric motor to maintain rotation of the engine without producing any engine torque.
