Abstract: According to one embodiment of the present disclosure, an industrial vehicle is provided comprising industrial vehicle hardware, tag reader, reader module, user interface, and vehicle controller. The tag reader and reader module cooperate to identify individual sequenced tags along an aisle path of a tag layout in accordance with a sequence list accessible to the reader module. The reader module compares a succession of sequenced tags with at least a portion of the accessible sequence list to determine if the succession of sequenced tags is in sequence along the aisle path in accordance with the sequence list and generates a missing tag signal for a malfunctioning sequenced tag when the comparison of the succession of sequenced tags with the sequence list indicates a sequence irregularity in the plurality of sequenced tags. The reader module then correlates vehicle functionality with the malfunctioning sequenced tag when a missing tag signal is generated.

Abstract: In location-based geo-feature implementations, messages for conveyance on an industrial vehicle are determined based on a current operating state of the industrial vehicle, information about a zone with expected operating conditions, and the industrial vehicle's location. When the industrial vehicle enters the zone, the current operating state of the industrial vehicle is compared to the expected operating state, which determines the message for display. Further, the current operating state may change the way the message is displayed. In vehicle-based implementations, vehicle data is collected and analyzed to generate messages upon the triggering of predetermined events. The detection of an event can be combined with vehicle position data to create an event record that captures location. Tools are also provided for setting up, managing and using the above capabilities.
