STEER CONTROL MANEUVERS FOR MATERIALS HANDLING VEHICLES
First Claim
Patent Images
1. A method for a materials handling vehicle to automatically perform a steer correction maneuver comprising:
- receiving sensor data from at least one sensing device by a controller on a materials handling vehicle;
detecting based on the received sensor data that an object is located in an environment monitored by the controller, the environment comprising an area around the vehicle;
determining how far the detected object is from a reference coordinate associated with the vehicle; and
automatically performing a steer correction maneuver by steering the vehicle away from the detected object, wherein an angle of steer correction is dependent upon how far from the reference coordinate the detected object is determined to be.

Abstract
A materials handling vehicle automatically implements steer maneuvers when objects enter an environment around the vehicle. A steer correction maneuver is automatically performed by steering the vehicle away from the detected object, wherein an angle of steer correction and/or a rate of change of the steering angle that is implemented to achieve a desired angle of steer correction is dependent upon how far from a reference coordinate associated with the vehicle the detected object is determined to be.
