Electric cam phaser control systems and methods
A system for an engine includes a motor driver module, a target phase angle module, and a correlation control module. The motor driver module controls an electric motor of a camshaft phaser based on a target angle defined by a crankshaft position and a camshaft position. The target phase angle modul...

| description | A system for an engine includes a motor driver module, a target phase angle module, and a correlation control module. The motor driver module controls an electric motor of a camshaft phaser based on a target angle defined by a crankshaft position and a camshaft position. The target phase angle module selectively sets the target angle to a first phase angle before a deceleration fuel cutoff (DFCO) event and selectively transitions the target angle to a predetermined phase angle during the DFCO event. The correlation control module selectively compares a value of the crankshaft position with a predetermined crankshaft position range during the DFCO event. |
