Publication number: 20240059145Abstract: A materials handling vehicle comprises a processor, a throttle, and a zone sensing subsystem coupled to the processor. The processor, responsive to the zone sensing subsystem detecting that the materials handling vehicle is in a restricted operational zone, controls the materials handling vehicle by applying a maximum vehicle operational limit of the materials handling vehicle to a magnitude that is at or below an operational limit of the restricted operational zone. Further, the processor overrides the maximum vehicle operational limit based on application of a throttle neutral action.Type: ApplicationFiled: October 24, 2023Publication date: February 22, 2024Applicant: Crown Equipment CorporationInventor: Kashyap Chandrasekar
