    摘要： A system and method for controlling an internal combustion engine control an actuator in response to variations of intake airflow relative to an average intake airflow to manage induction acoustics. The system and method may include controlling an actuator, such as a throttle valve, to increase intake manifold vacuum in response to intake airflow. In an engine having electronically actuated intake and/or exhaust valves, intake airflow is estimated based on at least engine speed and valve timing and compared to a measured intake airflow to determine a first difference. The measured airflow is divided into a steady-state and transient term or component with a second difference determined based on the transient component and a target value. Throttle valve position is selectively controlled to increase vacuum in response to a combination of the first and second difference to manage induction acoustics.
