Abstract
A cylinder control module generates a desired cylinder activation/deactivation sequence for a future period based on Q predetermined cylinder activation/deactivation sub-sequences used during a previous period, a desired number of cylinders to be activated during a predetermined period including the previous and future periods, and an operating condition. Q is an integer greater than zero. The cylinder control module activates and deactivates opening of intake and exhaust valves of first and second ones of the cylinders that are to be activated and deactivated based on the desired cylinder activation/deactivation sequence, respectively. A fuel control module provides and disables fuel to the first and second ones of the cylinders, respectively.
