An air dynamic method for detecting a stationary and a transient state for a cam phaser movement

摘要

An air-dynamic system for detecting a steady state for a cam phaser movement of an internal combustion engine comprises a cam position detection device and a control module. The cam position detecting means generates a position signal based on a position of the cam phaser of the motor. The control module receives the position signal and applies first and second filters to the position signal to select a transient or stationary state. The control module also calculates an estimated air value based on the selection of the transient or steady state.
