Abstract: A system for a vehicle includes a rate of change module, a period estimation module, a deceleration fuel cutoff (DFCO) module, and an injection control module. The rate of change module determines a rate of change of an engine speed. While an engine is being fueled, the period estimation module determines an estimated period of a next DFCO event based on the rate of change of the engine speed. The DFCO control module selectively generates a DFCO signal based on the estimated period. The injection control module cuts off fuel to the engine when the DFCO signal is generated.

Abstract: An engine control system includes a fuel cutoff (FCO) module, a fuel control module, and a spark control module. The FCO module, when a FCO event is disabled, determines a feed-forward (FF) number of cylinders to offset a delay period associated with supplying fuel to the cylinders of an engine and selectively maintains a FCO torque request at a predetermined torque. The fuel control module commands fuel be supplied to the FF number of cylinders of the engine when the FCO event is disabled. The spark control module maintains a spark timing of the FF number of cylinders at a fully retarded spark timing based on the FCO torque request.

Abstract: A powertrain system includes an engine control module that generates a negative torque transition signal based on a pending negative torque event of an engine. A transmission control module receives the negative torque transition signal from the engine control module. The transmission control module increases a slip speed of a torque converter clutch in preparation for the pending negative torque event by adjusting pressure in the torque converter clutch prior to the pending negative torque event. The transmission control module decreases the slip speed in the torque converter clutch based on completion of a transition at least one of to the pending negative torque event and from the pending negative torque event.
