Abstract
Engine load for a supercharged engine is estimated by determining airflow upstream of a throttle valve that is upstream of a supercharger, subtracting a value representative of a change in air mass between the throttle valve and the supercharger based on a measured change in pressure between the throttle valve and the supercharger, and subtracting a modification value dependent upon a current engine speed and a signal representative of a pressure at the intake manifold.
