Abstract
A method for correction of intake pulsation is provided. The method includes calculating a basic air charge amount of a cylinder or a charge amount conversion coefficient based on a measurement value of a sensor disposed in an intake system of an engine. A basic pulsation compensation coefficient for correcting an intake amount from a basic waveform of pulsation is calculated based on opening/closing of an intake valve and engine RPM. The basic pulsation compensation coefficient is then corrected when the basic waveform of the pulsation is changed.
