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 17):
A system as recited in  claim 13 , wherein the NVH controller includes:\n a variable filter arranged to shape the response of the actuator during operation of the engine at the first effective firing fraction; and a filter coefficient setter arranged to set selected filter coefficients of the variable filter.
