Mobile-machine navigation system
First Claim
1. A method of navigating a mobile machine dependent upon a relationship of the mobile machine to a target path, the method comprising:
- in response to the mobile machine deviating from a first navigational dead band, operating a steering system to change the heading of the mobile machine; and
subsequently, operating the steering system to make a heading change of the mobile machine only in response to predetermined events, including operating the steering system to make a heading change of the mobile machine if the mobile machine deviates from a second navigational dead band.

Abstract
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.

13. A mobile-machine navigation system for navigating a mobile machine, the mobile-machine navigation system comprising:
-
navigation controls, including a steering system operable to adjust the heading of the mobile machine;
the navigation controls being configured to execute a method of navigating the mobile machine dependent upon the relationship of the mobile machine to a target path, the method of navigating the mobile machine including operating in a first mode until the mobile machine deviates from a first navigational dead band;
in response to the mobile machine deviating from the first navigational dead band, operating the steering system to change the heading of the mobile machine and, subsequently, operating in a second mode until the mobile machine reaches a target zone, the target zone including the target path; and
in response to the mobile machine reaching the target zone, operating the steering system to make a heading change and, subsequently, returning to operation in the first mode. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method of navigating a mobile machine dependent upon the relationship of the mobile machine to a target path and a first navigational dead band defined as a function of the target path, the method comprising:
in response to each deviation of the mobile machine from the first navigational dead band, operating a steering system to make a heading change to direct the mobile machine toward a portion of the target path ahead of a point on the target path nearest the mobile machine. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. A mobile-machine navigation system for navigating a mobile machine, the mobile-machine navigation system comprising:
-
navigation controls, the navigation controls including a steering system; and
the navigation controls being configured to execute a method of navigating the mobile machine dependent upon a relationship of the mobile machine to a target path and a target zone that includes the target path, the method of navigating the mobile machine including in response to the mobile machine moving from off the target zone onto the target zone, operating the steering system to make a heading change toward a portion of the target path ahead of a point on the target path nearest the mobile machine. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)
