Abstract: A method for automatically guiding a vehicle along at least a first of a plurality of rows comprising predefined centerlines. At least a second of the rows comprises a number of objects of known dimensions positioned at known locations along the centerline thereof. The method comprises the steps of scanning the objects from the vehicle, generating a set of data points representative of the locations of the objects relative to the vehicle, determining a sensed position and heading of the vehicle from the data points, comparing the sensed position and heading of the vehicle to a position and direction of the first row centerline, and generating offset and heading errors for the vehicle based on differences between the sensed position and heading of the vehicle and the position and direction of the first row centerline.

Abstract: In accordance with aspects of the present disclosure, a method of limiting a vehicle speed is provided. The method includes limiting the speed of the vehicle to a predetermined limit under normal operating conditions. The method further includes selectively engaging an override condition in response to an operator generated input. During the override condition, the vehicle can exceed the predetermined limit by a specified offset. The override condition is not available when the vehicle has traveled in the override condition for a predetermined number of miles.
