Abstract

A system according to the principles of the present disclosure includes a vibration prediction module and a firing sequence module. The vibration prediction module predicts a vibration response of a vehicle based on a firing sequence of an engine when a cylinder of the engine is deactivated. The firing sequence module adjusts the firing sequence of the engine based on the predicted vibration response of the vehicle.
