Abstract

A system and method is provided for adaptive control of at least one parameter of an auto guidance control algorithm for a vehicle. The parameters may be varied according to a previously established look up table, or automatically adapted through the use of control logic, such as a 'fuzzy logic' algorithm. The control parameters that can be adaptively controlled include steered wheel turn rate, proportional valve current gain, line acquisition rate and/or auto guidance control valve current limits. The control algorithm responds to the vehicle's operating parameters such as vehicle speed, tracking error, predicted heading, and hydraulic oil temperature to make adjustments to the auto guidance control parameters.
