  • Patent number: 9908527
    Abstract: A materials handling vehicle includes at least one contactless obstacle sensor that scans at least two speed zones, each speed zone being defined in an area at least partially in front of a forward traveling direction of the vehicle and being associated with a unique predetermined maximum speed greater than zero (0) miles per hour. A controller that receives information obtained from the at least one obstacle sensor and, if the vehicle is traveling under remote control, the controller is configured to limit the vehicle speed to the predetermined maximum speed of a corresponding one of the at least two speed zones based upon the detection of an obstacle in that speed zone.

  • Patent number: 9645968
    Abstract: A supplemental control system for a materials handling vehicle comprises one or more sensors capable of defining multiple contactless detection zones at least towards the front of the forward travel direction of a remotely controlled vehicle. The vehicle responds to the detection of objects within the designated zones based upon predetermined actions, such as to slow down or stop the vehicle, and/or to take other action, such as to perform a steer angle correction.

  • Patent number: 9421963
    Abstract: A materials handling vehicle is provided comprising: a frame; wheels supported on the frame; a traction motor coupled to one of the wheels to effect rotation of the one wheel; a speed control element operable by an operator to define a speed control signal corresponding to a desired speed of the traction motor; a system associated with a steerable wheel to effect angular movement of the steerable wheel; and control apparatus coupled to the speed control element to receive the speed control signal, and coupled to the traction motor to generate a drive signal to the traction motor in response to the speed control signal to control the operation of the traction motor. The control apparatus may determine an acceleration value for the traction motor based on at least one of an angular position of the steerable wheel, a speed of the traction motor and a current position of the speed control element as defined by the speed control signal.

  • Patent number: 9145163
    Abstract: A system for providing an electrical steering assist for a materials handling vehicle includes a drive housing; a steerable wheel coupled to the drive housing; a steering arm pivotally mounted to the drive housing; a steer drive unit coupled to the steerable wheel; an input sensing device; and a controller. The steering arm is operatively configured to determine a steering direction of the steerable wheel. The input sensing device is arranged to detect a turning force applied to the steering arm by an operator, wherein the turning force is provided to change the angle of travel of the vehicle. The input sensing device includes a strain measuring assembly defining a strain sensitive region between the steering arm and the steer drive unit. The controller is operatively configured to control the steer drive unit to turn the steerable wheel based upon a signal from the input sensing device.

  • Patent number: 9025827
    Abstract: A method is provided for controlling forks of a vehicle. The method may comprise: while the forks of the vehicle are moving vertically, acquiring a series of images of a scene of a physical environment in which a plurality of pallets are visible; identifying in each image, by a computer system, one or more scored candidate objects, each potentially corresponding to a respective one of the plurality of pallets; for each of the one or more scored candidate objects, tracking, by the computer system, a respective location in each of at least two images of the series; determining for each of the one or more scored candidate objects a respective, associated height in the physical environment; and stopping, by the computer system, the forks of the vehicle at a height in the physical environment based on the height of a specific one of the scored candidate objects.
