  • Patent number: 9002581
    Abstract: A materials handling vehicle automatically implements steer maneuvers when objects enter one or more zones proximate the vehicle, wherein the zones are monitored by a controller associated with the vehicle. The controller tracks objects in the zones via sensor data obtained from at least one obstacle sensor located on the vehicle and via dead reckoning. The objects are tracked by the controller until they are no longer in an environment proximate the vehicle. Different zones result in different steer maneuvers being implemented by the controller.

  • Publication number: 20150057843
    Abstract: A remote control device worn by an operator in combination with a materials handling vehicle includes a wireless transmitter and control structure in communication with the wireless transmitter. The control structure is actuated by the operator to cause the wireless transmitter to generate a travel request signal. The vehicle includes a traction control system, a receiver for receiving travel request signals from the wireless transmitter, at least one sensor, and a controller. The sensor(s) is configured to detect objects near the vehicle or to detect a person on a vehicle operating platform. The controller is configured to decide not to cause the traction control system to advance the vehicle in response to a travel request signal from the receiver if the status from one or more of the at least one sensor is indicative of the presence of either: an object near the vehicle; or a person on the platform.

  • Publication number: 20140343758
    Abstract: A supplemental remote control system for a materials handling vehicle includes a wireless remote control device that is useable by an operator interacting with the materials handling vehicle. Actuation of a travel control on the remote control device causes a wireless transmitter on the device to transmit a travel request to the vehicle. The remote control system further includes a receiver for receiving transmissions from the wireless transmitter at the vehicle and a controller at the vehicle in communication with the receiver for implementing the travel request. The wireless remote control device further includes an input component, wherein actuation of the input component causes the wireless transmitter to wirelessly transmit a second type of request to the receiver on the vehicle requesting the controller to implement a second vehicle function other than to advance the vehicle.

  • Publication number: 20140195121
    Abstract: A materials handling vehicle implements a steer maneuver to hug an object. A controller on the vehicle receives sensor data from at least one sensing device and detects that a selected object is in an environment proximate the vehicle using the received sensor data. The controller performs a steer maneuver by causing the vehicle to steer such that the vehicle is substantially maintained at a desired distance from the selected object as the vehicle travels on a desired heading.

  • Publication number: 20130197760
    Abstract: A materials handling vehicle includes a power unit, a load handling assembly, at least one first obstacle detector, and at least one second obstacle detector. The at least one first obstacle detector is mounted at a first location on the power unit to detect an object located along a path of travel of the power unit beyond a non-detect zone of the at least one first obstacle detector. The at least one second obstacle detector is mounted at a second location on the power unit, spaced from the first location in a first direction, and is capable of detecting an object in the non-detect zone of the at least one first obstacle detector.

  • Patent number: 8452464
    Abstract: A materials handling vehicle automatically applies a steer correction maneuver if an object is detected in a steer bumper zone in front of the vehicle. A controller detects whether an object is in front of the materials handling vehicle and automatically determines whether a steer correction maneuver should be to the right or left of the traveling direction of the materials handling vehicle. The materials handling vehicle automatically steer corrects the vehicle, e.g., at a determined steer angle that is opposite the direction to the detected position of the object, and accumulates the distance traveled by vehicle while steer correction is being performed. The vehicle then automatically counter steers the vehicle, e.g., by a determined steer amount, in the opposite direction as the steer correction for a percentage of accumulated steer distance traveled. After performing the counter steer maneuver, the vehicle may, for example, resume a substantially straight heading.
