Abstract:
Systems and methods for reducing noise or vibration generated by an internal combustion engine are described. An engine controller is arranged to operate the working chambers of the engine in a cylinder output level modulation manner. A noise/vibration reduction unit actively control of a device that is not a part of the powertrain. The device is controlled in a feed forward manner to alter an NVH characteristic of the vehicle in a desired manner based at least in part on a characteristic of the cylinder output level modulation operation of the engine.

Claim (Index 21):
A method of mitigating or adjusting an NVH characteristic of a vehicle having a powertrain that includes an engine capable of cylinder output level modulation operation, the engine including a plurality of working chambers, the method comprising:\n operating the engine in a cylinder output level modulation mode at a first effective firing fraction; and actively controlling a device that is not a part of the power train in a feed forward manner during the cylinder output level modulation operation at the first effective firing fraction, to alter the NVH characteristic of the vehicle in a desired manner based at least in part on specific working chamber output level decisions, each specific working chamber output level decision being indicative of a desired output level for an individual associated working chamber during a single associated firing opportunity, wherein for each firing opportunity, the device is controlled differently during the associated firing opportunity based on the associated output level decision, whereby the control of the device varies in accordance with the output level decisions over the course of each engine cycle during the cylinder output level modulation operation of the engine at the first effective firing fraction.
