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.

A vehicle driveline component that employs a latching actuator to toggle between a first operation mode and a second operational mode. The latching actuator includes first and second actuator structures, a biasing spring, which biases the second actuator structure away from the first actuator structure, a linear motor, which can be operated to drive the second actuator structure toward the first actuator structure, and a plurality of linkages that cooperate with the biasing spring to releasably lock the second actuator structure relative to the first actuator structure in each of an extended position and a retracted position.
