Abstract
A method for controlling a powertrain of a vehicle adjusts a minimum allowed airflow based on operating conditions. Specifically, when conditions of engine speed and/or vehicle speed area away from idle conditions, no increasing of the minimum allowed airflow is carried out. However, when conditions of engine speed and/or vehicle speed area approaching idle conditions, the minimum allowed airflow is increased to the required airflow for those idle conditions.
