Abstract
A system and method for calibrating and controlling an active dampening system for a chassis of a vehicle having an engine involve operating the engine in a cylinder deactivation mode and, during the cylinder deactivation mode, (i) receiving, from a set of sensors, measured vibrations on first and second frame rails of the chassis, (ii) generating control signals for a set of actuators based on the measured vibration of the first and second frame rails, each actuator being configured to generate a vibrational force in at least one direction, and (iii) outputting, to the set of actuators, the control signals, wherein receipt of the control signals cause the set of actuators to generate vibrational forces that dampen the vibration of the first and second frame rails, respectively, to decrease noise/vibration/harshness (NVH).
