Abstract
A computer-implemented apparatus and method for inferring power steering load and for controlling airflow to an engine of a vehicle having an engine speed. A sensor which is connected to the engine senses the engine speed of the engine. An engine speed reference data table stores at least one engine reference speed, and a reference comparator module which is connected to the sensor and to the reference data table performs a comparison between the sensed engine speed and the engine reference speed. The airflow to the engine is controlled based upon the comparison.
