INDUSTRIAL VEHICLE COMPRISING TAG READER AND READER MODULE
First Claim
1. An industrial vehicle comprising industrial vehicle hardware, a user interface, a tag reader, a reader module, and a vehicle controller, wherein:
- the industrial vehicle hardware comprises storage and retrieval hardware and a vehicle drive mechanism;
the tag reader and the reader module cooperate to identify individual tags of a tag layout;
the individual tags of the tag layout comprise a plurality of zone identification tags and a plurality of zone tags;
each zone identification tag occupies a position in the tag layout that corresponds to a unique set of zone tags;
each unique set of zone tags comprises a plurality of zone tags;
the reader modulediscriminates between the plurality of zone identification tags and the plurality of zone tags identified in the tag layout,correlates an identified zone identification tag with a unique set of zone tags, andcorrelates vehicle functionality with an identified zone tag within the unique set of zone tags, tag-dependent positional data derived from the identified zone tag, or both; and
the vehicle controller controls operational functions of the industrial vehicle hardware in response to (i) the correlation of vehicle functionality with an identified zone tag, tag-dependent positional data, or both, (ii) user input at a user interface of the industrial vehicle, or (iii) both.

Abstract
According to one embodiment of the present disclosure, an industrial vehicle is provided comprising industrial vehicle hardware, a user interface, tag reader, reader module, and vehicle controller. The tag reader and the reader module cooperate to identify individual tags of a tag layout comprising a plurality of zone identification tags and a plurality of zone tags. Each zone identification tag occupies a position in the tag layout that corresponds to a unique set of zone tags. Each unique set of zone tags comprises a plurality of zone tags. The reader module discriminates between the plurality of zone identification tags and the plurality of zone tags identified in the tag layout, correlates an identified zone identification tag with a unique set of zone tags, and correlates vehicle functionality with an identified zone tag within the unique set of zone tags, tag-dependent positional data derived from the identified zone tag, or both.

38. An industrial vehicle comprising storage and retrieval hardware, a tag reader, a reader module, and a vehicle controller, wherein:
-
the storage and retrieval hardware is configured to store and retrieve items from selected storage elements positioned along an aisle path; the tag reader and the reader module cooperate to identify individual tags along the aisle path; the tag reader comprises two read antennas positioned on opposite sides of a longitudinal travel axis of the industrial vehicle; the read antennas define respective read ranges and generate respective tag read signals when tags enter the respective read ranges of the read antennas; the tag reader and the reader module further cooperate to generate a vehicle direction signal when the individual tags are identified primarily with reference to tag read signals from only one of the two read antennas; and the vehicle controller controls operational functions of the storage and retrieval hardware partially as a function of the vehicle direction signal.
