Claim:
1. Apparatus for aligning a vehicle with an inductive charging system, comprising: (a) a transformer including a stationary primary coil and a secondary coil mounted on the vehicle; (b) at least one alignment coil assembly including at least three assembly coils, each assembly coil having a longitudinal axis and oriented orthogonally to a plane defined by the longitudinal axes of two other assembly coils, said alignment coil assembly being arranged in the vicinity of said secondary coil, said primary coil generating a magnetic field when energized to induce a voltage in each assembly coil; and (c) a controller connected with said alignment coil assembly for generating an output signal corresponding to the voltage induced in each assembly coil by the magnetic field, each voltage corresponding to the position of the secondary coil relative to the primary coil.
