Abstract
Based on a desired average number of activated cylinders per sub-period of a predetermined period including P sub-periods, a cylinder control module selects one of N predetermined cylinder activation/deactivation patterns. The selected cylinder activation/deactivation pattern corresponds to Q activated cylinders per sub-period, Q is an integer between zero and a total number of cylinders of an engine, inclusive, P is an integer greater than one, and the desired average number of active cylinders is a number between zero and the total number of cylinders of the engine. The cylinder control module also determines an adjusted cylinder activation/deactivation pattern based on the selected predetermined cylinder activation/deactivation pattern, generates a desired cylinder activation/deactivation pattern for the predetermined period using the selected predetermined cylinder activation/deactivation pattern during a first number of the P sub-periods and using the adjusted cylinder activation/deactivation pattern during a second number of the P sub-periods.
