Abstract

A variety of methods, devices and filters are described that are suitable for averaging measured power train operating parameters over a period that varies as a function of an engine cylinder firing characteristic such as a current operational firing fraction or firing sequence. The averaged measured operating parameter may be used in a variety of different engine control related functions, calculations and/or operations. The described techniques and devices are particularly well suited for use during skip fire operation of an engine.
