Steer correction for a remotely operated materials handling vehicle

A materials handling vehicle automatically applies a steer correction maneuver if a structure is detected in either a left or right multi-zone steer bumper zone (to the left or right of the vehicle). A controller detects whether a structure is to the side of the materials handling vehicle and automa...

description A materials handling vehicle automatically applies a steer correction maneuver if a structure is detected in either a left or right multi-zone steer bumper zone (to the left or right of the vehicle). A controller detects whether a structure is to the side 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 establishes a hysteresis such that the controller maintains a heading by keeping the structure between the first, outer steer bumper limit and the second, inner steer bumper limit of the left or right multi-zone steer bumper zone. After performing the counter steer maneuver, the vehicle may, for example, resume a substantially straight heading.
