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.

Steer maneuvers for materials handling vehicles

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.

Object tracking and steer maneuvers for materials handling vehicles

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.

Steer correction for a remotely operated materials handling vehicle

A compressor protection and control subsystem for a rotary compressor provides temperature pressure, mis-wiring and vibrational protection for the scroll machine. The vibrational protection comprises a vibration sensor which is integrated on the circuit board of the protection and control subsystem. The vibration sensor, in conjunction with at least one timer, monitors the vibrations of the scroll machine and will shut down the machine when excess vibrations are sensed over a prespecified period of time. The temperature system monitors operating temperature conditions the pressure system monitors operating pressures and the mis-wiring system monitors the power supplied to the compressor. Once an undesirable characteristic is identified, the operation of the scroll machine is stopped. These protection systems are integrated into a single subsystem which identifies the reason of shutting off the scroll machine in order to simplify repairs needed. The subsystem incorporates a gateway and/or a serial peripheral interface in order to communicate with a central operating and control system.
