Claim 19:
20. The method of claim 17, further comprising:
eliminating the obstacle collision error, the pinch point error, or both, on both sides of the materials handling vehicle when possible when possible by modification of the proposed travel path;
mitigating the obstacle collision error, the pinch point error, or both, by eliminating the obstacle collision error, the pinch point error, or both, on at least one side of the vehicle when the proposed travel path is not modifiable to eliminate the obstacle collision error, the pinch point error, or both, on both sides of the vehicle;
setting an impingement distance on each side equidistant and mark an area of the proposed travel path including the obstacle collision error, the pinch point error, or both, as a hazard area, when the proposed travel path is not modifiable to mitigate the obstacle collision error, the pinch point error, or both, by eliminating the obstacle collision error, the pinch point error, or both, on at least one side of the vehicle, though a collision is avoidable, wherein the degree of potential impingement comprises the impingement distance that is an overlap distance at candidate positions indicative of an overlap between the dynamic exterior boundary or the dynamic clearance boundary of the materials handling vehicle and obstacle data; and
automatically stopping the materials handling vehicle to avoid the collision when the proposed travel path is not modifiable to mitigate the obstacle collision error, the pinch point error, or both, by eliminating the obstacle collision error, the pinch point error, or both, on at least one side of the vehicle, and a collision is unavoidable.
