Abstract
Guiding a leading vehicle according to a desired trailing vehicle path includes generating one or more proceeding paths for one or more intermediate locations along an implement train between a trailing vehicle first location and a leading vehicle second location. The proceeding paths generated with a propagation and transformation algorithm that propagates a preceding path of one of the first location, such as the desired trailing vehicle path, or one of one or more intermediate locations to an immediately proceeding location, and transforms the preceding path according to dimensional characteristics of the implement train. A second guiding path is generated for the leading vehicle second location with the algorithm based on the immediately preceding path of the intermediate location closest to the second location. The method facilitates guidance of the trailing vehicle along the desired trailing vehicle path without navigation markers on the implement train except for the leading vehicle.
