Abstract:
Systems and methods are described for mitigating vehicle vibration through the control of a variable spring absorber that is part of a powertrain that includes the engine. In some such embodiments, an absorption frequency of the variable spring absorber is tuned in a feed forward manner based at least in part on the current engine speed and a factor indicative of the minimum repeating firing sequence cycle length associated with the current effective firing fraction (which in many implementations may be the denominator of the firing fraction).

Claim (Index 10):
A system for reducing at least one of noise and vibration generated by an internal combustion engine during operation of the engine, the system comprising:\n a powertrain that includes the engine and a variable spring absorber; an engine controller configured to direct operation of the engine in a cylinder output level modulation mode; and an absorber controller arranged to set an absorption frequency for the variable spring absorber during cylinder output level modulation operation of the engine, wherein the absorption frequency is set based at least in part on a minimum repeating pattern length of a repeating firing sequence associated with an operational firing fraction and level fraction.
