1. A cylinder control system of a vehicle, comprising:

  • a cylinder control module that;

    selects one of N predetermined cylinder activation/deactivation patterns as a desired cylinder activation/deactivation pattern for cylinders of an engine, wherein N is an integer greater than two;

    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 pattern; 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 pattern; and

    a fuel control module that provides fuel to the first ones of the cylinders and that disables fueling to the second ones of the cylinders,wherein the cylinder control module further;

    determines M possible ones of the N cylinder activation/deactivation patterns, wherein M is an integer greater than or equal to one;

    selectively compares the M possible cylinder activation/deactivation patterns with the desired cylinder activation/deactivation pattern; and

    selectively updates the desired cylinder activation/deactivation pattern to one of the M possible cylinder activation/deactivation patterns.
