Abstract
The method includes the following features. A first pressure upstream of a throttle is received. A temperature upstream of the throttle is received. A second pressure within an intake manifold is received. An engine speed is received. An air flow is estimated based on the received first pressure, the received temperature, the received second pressure, and the received engine speed. Estimating the air flow includes determining one or more models to use for calculating air flow based on the received first pressure and the received second pressure. The models include a throttle flow model, a port flow model, or both.
