Abstract:
A variety of methods and arrangements are described for controlling transitions between firing fractions during skip fire or other dynamic firing level modulation operation of an engine. In general, actuator first transition strategies are described in which an actuator position (e.g., cam phase, TCC slip, etc.) is changed to, or close to a target position before a corresponding firing fraction change is implemented. When the actuator change associated with a desired firing fraction change is relatively large, the firing fraction change is divided into a series of two or more firing fraction change steps. A number of intermediate target selection schemes are described as well.

Claim (Index 16):
A method of controlling an engine to deliver a requested engine output, the method comprising:\n while the engine is operating at a first effective firing fraction having an associated first cam phase, determining a desired second effective firing fraction and an associated second cam phase, the second cam phase being different than the first cam phase; initiating a transition from the first cam phase to the second cam phase; after an actual cam phase is at or within a predetermined range of the second cam phase transitioning to the second effective firing fraction, wherein transition to the second effective firing fraction is initiated only after the actual cam phase is at or within the predetermined range of the second cam phase; and directing operation of the engine during the transitions to deliver the requested engine output, whereby an actual commanded effective firing fraction gradually changes over the course of the transition from the first effective firing fraction to the second effective firing fraction, and wherein operating the engine at at least one of the first and second effective firing fractions involves operating the engine in a multi-level skip fire or multi-charge level operating mode.
