  • Patent number: 11947361
    Abstract: A system is provided that controls an industrial vehicle responsive to encountering working environment tags. The system comprises a transceiver and a tag reader mounted on the industrial vehicle. Also, the system comprises an information processing device communicably coupled to the transceiver and the tag reader. The information processing device comprises a processor in data communication with memory. In this regard, the processor is programmed to receive an identifier of a tag detected by the tag reader while the industrial vehicle is being operated within a work environment, and access electronically, a predetermined action based upon the identifier of the detected tag. The processor is further programmed to communicate information across a vehicle network bus to at least one electronic component of the industrial vehicle to perform the predetermined action, wherein the predetermined action automatically modifies a working state of the industrial vehicle.

  • Patent number: 11945705
    Abstract: Controlling a maximum vehicle speed for an industrial vehicle includes determining, by a processor of the industrial vehicle, a torque applied to the traction wheel of the industrial vehicle; converting the torque to an equivalent force value; and determining an acceleration of the industrial vehicle while the torque is applied to the traction wheel. Additional steps include calculating a load being moved by the industrial vehicle, based at least in part on the acceleration and the equivalent force value; and controlling the maximum speed of the industrial vehicle based on the calculated load being moved by the industrial vehicle.

  • Patent number: 11935426
    Abstract: Industrial vehicle monitoring for modification of vehicle operator behavior comprises storing data identifying an event associated with the operation of an industrial vehicle, the data having a performance parameter to evaluate against the event. Further, operation of the industrial vehicle is monitored for an event. When an occurrence of the event is detected, event data that characterizes an action of a vehicle operator is recorded into memory. The recorded event data is evaluated against the performance parameter to determine whether the vehicle operator demonstrated appropriate behavior for the detected event, and a behavior modification action is determined based on the evaluation of the recorded event data against the performance parameter. An output message is conveyed on the industrial vehicle to perform the behavior modification action.

  • Publication number: 20240083272
    Abstract: A materials handling vehicle including a vehicle-side charging contact assembly coupled to a battery, a steerable drive wheel defining a drive wheel track width W, and a pair of load wheels defining a load wheel gap G between the pair of load wheels that is larger than the drive wheel track width W. A charging station includes a pair of floor-side charging contacts configured to transfer charging current to the vehicle-side charging contact assembly. The pair of floor-side charging contacts define an inner contact spacing S1 that is larger than the drive wheel track width W, and an outer contact spacing S2 that is larger than the inner contact spacing S1 and smaller than the load wheel gap G to permit passage of the steerable drive wheel between the floor-side charging contacts, followed by passage of the pair of load wheels outside of the floor-side charging contacts.

  • Patent number: 11914394
    Abstract: A materials handling vehicle comprising a path validation tool and a drive unit, steering unit, localization module, and navigation module that cooperate to navigate the vehicle along a warehouse travel path. The tool comprises warehouse layout data, a proposed travel path, vehicle kinematics, and a dynamic vehicle boundary that approximates the vehicle physical periphery. The tool executes path validation logic to determine vehicle pose along the proposed travel path, update the dynamic vehicle boundary to account for changes in vehicle speed and steering angle, determine whether the dynamic vehicle boundary is likely to intersect obstacles represented in the layout data based on the determined vehicle pose at candidate positions along the proposed travel path, determine a degree of potential impingement at the candidate positions by referring to the dynamic vehicle boundary and obstacle data, and modify the proposed travel path to mitigate the degree of potential impingement.

  • Publication number: 20240059145
    Abstract: 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.
