ABSTRACT:
A powertrain system includes a hybrid transmission coupled to an engine and an auxiliary hydraulic pump. The auxiliary hydraulic pump is commanded to operate at a predetermined speed only when enable criteria are met. An engine-off state is inhibited based upon a difference between a commanded speed and a monitored operating speed of the auxiliary hydraulic pump.
