Abstract
A vehicle driveline component includes an armature disposed and moveable along a translation axis, a coil assembly having a coil, a coil driver, an oscillator circuit having a resonant circuit, and a controller. The oscillator circuit is electrically coupled to the coil such that the coil defines a portion of the resonant circuit. The oscillator circuit generates an oscillating signal having a frequency that varies based on a spacing between the armature and the coil assembly along the translation axis. The controller applies a drive signal to the coil driver to have the coil driver provide a modulating power signal to the coil to generate an electromagnetic field that causes relative motion between the coil assembly and the armature along the translation axis. The controller determines a system response characteristic related to the spacing between the armature and the coil assembly based on the oscillating signal.
