Abstract

A control module and system includes a camshaft position module that determines a camshaft position change of a crankshaft. The control module also includes a cam phaser velocity module determines a cam phaser velocity based on the camshaft position change. A cam phaser velocity module determines a compensation factor based on the cam phaser velocity. A cam position compensation module generates a corrected cam position signal based on the compensation factor.
