Abstract
Internal combustion engine control is generally in accordance with RPM and torque modes. Transition from RPM to torque control is accomplished by employing a mass airflow term accounting for any nonequivalence between RPM mode and torque mode mass airflows corresponding respectively to an RPM mode mass airflow and a closed-throttle mass airflow contribution to a total torque mode mass airflow.
