    Abstract: A firing module determines a target number of activated cylinders of an engine based on a torque request and a present gear ratio of a transmission. A combination identification module, based on the torque request, identifies a combination including a possible number of activated cylinders and a possible transmission gear ratio, wherein at least one of: the possible number of activated cylinders is different than the target number of activated cylinders; and the possible transmission gear ratio is different than the present gear ratio of the transmission. A transitioning module, when a second fuel consumption for the possible number of activated cylinders and the possible transmission gear ratio is less than a first fuel consumption for the target number of activated cylinders and the present gear ratio, selectively: transitions the target number of activated cylinders to the possible number of activated cylinders; and transitions a target gear ratio of the transmission to the possible transmission gear ratio. An activation/deactivation module controls cylinder activation and deactivation based on the target number of activated cylinders.

    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.

    Abstract: A ranking module determines N ranking values for N predetermined cylinder activation/deactivation sequences of an engine, respectively. N is an integer greater than or equal to two. A cylinder control module, based on the N ranking values, selects one of the N predetermined cylinder activation/deactivation sequences as a desired cylinder activation/deactivation sequence for cylinders of the engine. The cylinder control module also: activates opening of intake and exhaust valves of first ones of the cylinders that are to be activated based on the desired cylinder activation/deactivation sequence; and deactivates opening of intake and exhaust valves of second ones of the cylinders that are to be deactivated based on the desired cylinder activation/deactivation sequence. A fuel control module provides fuel to the first ones of the cylinders and disables fueling to the second ones of the cylinders.
