Abstract
A vehicle guidance system for guiding a vehicle on a virtual track includes a waveguide connected to a member emitting electromagnetic radiation at a frequency between 1 and 100 kHz and disposed on the axis of the track to be followed. At least one set of two magnetic sensors disposed on the vehicle receive the field to determine the lateral offset of the vehicle relative to the axis of the track.
