Abstract

An automatic vehicle identification system for use in identifying and routing vehicles, such as railway cars or other vehicles which routinely travel a given track or path. A passive electronic device or electrical circuit is employed to intersect an energy field and respond thereto by generating a code in accordance with energy received and converted to coded electrical signals. Connected to the passive device is a short wave transmitter for transmitting signals generated by the electrical device when so energized. The electrical device may also comprise a plurality of different induction coils or antenna which serve to modify an energy field in a given manner, which modification may be detected by short wave sensing and converted to a coded electrical signal which is employed to identify the vehicle. In another form, a coded array of antenna or induction coils is provided which modify energy fields generated at check points or scanning locations along a trackway or roadway, wherein such energy field modifications are sensed at each such scanning location, resulting in the generation of an electrical code at each location and identification of the vehicle.
