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.

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.

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.

Abstract: A supplemental control system for a materials handling vehicle comprises a wearable control device, and a corresponding receiver on the materials handling vehicle. The wearable control device is donned by an operator interacting with the materials handling vehicle, and comprises a wireless transmitter to be worn on the wrist of the operator and a travel control communicably coupled to the wireless transmitter. Actuation of the travel control causes the wireless transmitter to transmit a first type signal designating a request to the vehicle. The receiver is supported by the vehicle for receiving transmissions from the wireless transmitter.
