Claim 14:
15. A work vehicle comprising:
at least first and second ground engaging units supporting a main frame and configured to controllably propel the work vehicle across a ground surface;
one or more onboard sensors having an external field of view to at least one side of the work vehicle; and
a controller functionally linked to the one or more onboard sensors and configured to:
detect a first position of at least a first component of the work vehicle relative to a first external point in a local reference system independent of a global reference system, using data provided from the one or more onboard sensors;
detect, upon the work vehicle having advanced from the detected first position a predetermined distance, a second position of the at least first component of the work vehicle relative to a second external point in the local reference system, using further data provided from the one or more onboard sensors;
determine an amount of mistrack error corresponding to a difference between the detected second position and an expected second position; and
generate an output signal based on the determined amount of mistrack error.
