Abstract
A method and system for estimating engine parameters in a combustion engine gas exchange system based on dynamic pressure readings taken by one or more pressure sensors. According to an exemplary embodiment, the method and system may use an artificial neural network (ANN) to process the dynamic pressure readings and any additional engine conditions that may have been provided.

13. A system for estimating an engine parameter, comprising:
-
a pressure sensor being located in a first section of a combustion engine gas exchange system and having an electronic output, wherein the pressure sensor provides dynamic pressure readings on the electronic output that are representative of the dynamic pressure behavior in the first section of the combustion engine gas exchange system; a mechanical device being located in the first section of the combustion engine gas exchange system so that it is in acoustic communication with the pressure sensor; and an electronic controller having an electronic input coupled to the electronic output of the pressure sensor, wherein the electronic controller estimates the position of the mechanical device from the dynamic pressure readings received from the pressure sensor. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
