1. A vehicle, comprising:
an inductive charging element;
a signal component located relative to the inductive charging element for common movement with the inducting charging element, wherein the signal component receives signals from a ground coil assembly that is not part of the vehicle;
a controller that determines positions of the inductive charging element relative to the target position based on time measurements of the signals;
a guidance control system that controls movement of the vehicle towards the ground coil assembly until a position of the inducting charging element has reached a threshold distance from the ground coil assembly; and
a motive device that, in response to the inducting charging element reaching the threshold distance from the ground coil assembly, controls movement of the inductive charging element and signal component, independent from movement of the vehicle, to position the inducting charging element in a defined position relative to the ground coil assembly.
