Abstract

Methods and controllers are described that facilitate the determination of an operational skip fire firing fraction for an engine based at least in part noise levels and/or vehicle vibration levels that are not induced by engine operation. In some embodiments, the firing fraction is determined based at least in part of noise or vibrations associated with road roughness and/or cabin noise levels.
