Abstract
An automated steering system for an agricultural vehicle operating in a row crop field. The automated steering system includes a correction system having a controller and an alignment sensor. The alignment sensor is disposed between two adjacently spaced crop rows and generates output signals indicative of the alignment sensor's lateral position relative to the two adjacently spaced crop rows as the vehicle advances in the forward direction of travel. The controller receives the generated output signals from the alignment sensor and determines an offset distance of said alignment sensor from a centerline between the two adjacently spaced crop rows. The controller outputs a modified vehicle position signal corresponding to the latitude and longitude position received from said GPS receiver shifted by the offset distance. The vehicle's on board navigation controller causes the vehicles on-board steering control system to steer the vehicle based on the modified vehicle position signal.
