Abstract
A method for determining the relationship between the heading of a machine and the course of machine travel is provided. The method includes the steps of determining a previous and current course of machine travel, and a current and filtered heading. An indicator is used to represent the relationship between the heading of the machine and the course of machine travel. The previous and current course of machine travel are compared and the indicator is responsively updated. The current and filtered heading are compared and the indicator is again responsively updated, and then the filtered heading is updated.
