Claim Text:
1. A cylinder control system of a vehicle, comprising: a target cylinder count module that determines a target number of cylinders of an engine to be activated during a future period, wherein the future period includes N sub-periods and N is an integer greater than or equal to two; a first sequence setting module that, when a change in the target number is less than a predetermined value: retrieves M predetermined percentages for M predetermined sequences for activating and deactivating cylinders of the engine, respectively, wherein M is an integer greater than or equal to two, respectively; and, generates a sequence indicating N target numbers of cylinders to be activated during the N sub-periods, respectively, based on use of the M predetermined sequences in proportion to the M predetermined percentages, respectively; a second sequence setting module that retrieves the M predetermined sequences for activating and deactivating cylinders of the engine, and that generates a target sequence for activating and deactivating cylinders of the engine during the future period using the M predetermined sequences in order according to the sequence indicating N target numbers of cylinders to be activated during the N sub-periods; and a cylinder actuator module that, during the future period: activates opening of intake and exhaust valves of first ones of the cylinders that are to be activated based on the target sequence; and deactivates opening of intake and exhaust valves of second ones of the cylinders that are to be deactivated based on the target sequence.
