Object tracking and steer maneuvers for materials handling vehicles

摘要

A materials handling vehicle having detection zone control comprising: a power unit for driving the vehicle; at least one contactless obstacle sensor on the vehicle that is operable to scan a scanned zone within an environment proximate to the vehicle, the environment comprising the scanned zone and a history zone; and a controller configured to receive information obtained from the at least one obstacle sensor and to define at least two zones within the environment based on the received information, the at least two zones comprising at least one stop zone and at least one steer away zone, wherein the controller: performs a stop action to bring the vehicle to a stop if an object is detected in the at least one stop zone; performs a steer maneuver to steer the vehicle away from an object detected in the at least one steer away zone; and tracks objects determined to be in the history zone until such objects are no longer in the environment. 5292268_2 (GHMatters) P93262.AU.1 1/05/2014 -- - - - - - - I-C
