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 13):
A system for reducing NVH generated by an internal combustion engine during cylinder output level modulation operation of the engine, the internal combustion engine having a plurality of working chambers and a cylinder output level modulation engine controller arranged to direct cylinder output level modulation operation of the engine, the system comprising:\n at least one actuator that is not part of a powertrain that includes the engine; and a NVH controller arranged to actively control actuation of the at least one actuator in a feed forward manner during cylinder level modulation operation of the engine at a first effective firing fraction to facilitate mitigation of an NVH characteristic associated with the cylinder level modulation operation of the engine at the first effective firing fraction, wherein the feed forward control is based at least in part on a current engine speed and at least one of a minimum repeating pattern length, the first effective firing fraction, a then current operational engine order, or a harmonic of the then current operational engine order.
