ABSTRACT:
A method for controlling an engine to reduce vehicle shuffle mode vibration during mode transition. The engine includes multiple cylinders, each with at least one electrically actuated valve, and the engine operates in a first mode having a first number of firing cylinders and a second mode having a second number of firing cylinders. The method comprises transitioning the engine from operating in the first mode to the second mode; adjusting at least a valve timing or lift of one of a last cylinder to be fired in said first mode and a first cylinder to be fired in said second mode to temporarily adjust a cylinder torque and thereby reduce vehicle shuffle mode vibration.
