System and method for controlling a supercharged engine with intake and duct throttle

摘要

A method and system for controlling an engine with a supercharger includes a bypass valve control module controlling a bypass valve for the supercharger having a bypass flow area in response to a desired manifold absolute pressure, an inlet valve control module controlling an inlet throttle for a supercharger in response to a bypass flow area and a port throttle control module controlling a port throttle in response to the desired mass airflow.
