Abstract:
Systems and methods for controlling an engine with cylinders that may be selectively activated and deactivated are presented. In one example, coefficients of a finite impulse response filter are adjusted responsive to changes in engine induction ratio so that undesirable frequencies output from engine sensors may be attenuated to improve engine control.
