Abstract: A system includes a cylinder control module that determines target numbers of cylinders of an engine to be activated during a period, determines, based on the target numbers and an engine speed, N predetermined sequences for controlling the cylinders of the engine during the period, determines whether a transition parameter is associated with at least one of the N predetermined subsequences and selectively adjusts at least one of the N predetermined subsequences based on the determination of whether a transition parameter is associated with at least two of the N predetermined sequences. The system further includes a cylinder actuator module that, during the period, controls the cylinders of the engine based on the N predetermined sequence and based on the at least one selectively adjusted predetermined sequences.

Abstract translation: 一个系统包括一个气缸控制模块，该气缸控制模块确定一段时间内要被激活的发动机气缸的目标数量，根据目标数量和发动机转速确定在此期间控制发动机气缸的N个预定次序，确定 转移参数是否与N个预定子序列中的至少一个相关联，并且基于确定转移参数是否与N个预定序列中的至少两个相关联来选择性地调整N个预定子序列中的至少一个。 所述系统还包括气缸致动器模块，所述气缸致动器模块在该时段期间基于所述N个预定顺序并且基于所述至少一个选择性调节的预定顺序来控制所述发动机气缸。
