A method of navigating a mobile machine dependent upon the relationship of
the mobile machine to a target path includes operating a steering system
to change the heading of the mobile machine in response to the mobile
machine deviating from a first navigational dead band. Additionally, the
method may include subsequently operating the steering system to make a
heading change of the mobile machine only in response to predetermined
events, which may include operating the steering system to make a heading
change of the mobile machine if the mobile machine deviates from a second
navigational dead band.
