Method and system for implement steering for agricultural vehicles
DCFirst Claim
1. A guidance system for directing a towed implement comprising:
- a first DGPS system, comprising an antenna located on a towing vehicle in operable communication with a receiver;
a second DGPS system comprising another antenna located on a towed implement in operable communication with another receiver;
a receiver configured to receive differential correctors from a reference GPS system;
a controller in operable communication with said first DGPS system, said second DGPS system, and said receiver, said controller generating a first steering command;
a steering mechanism on a towed implement in operable communication with said controller and configured to direct a towed implement based on said first steering command provided thereto.

8. A method for steering a towed implement comprising:
-
generating a differential corrector at a reference DGPS receiver and transmitting said differential corrector of a towing vehicle;
receiving said differential corrector;
receiving a first position from a first DGPS system corresponding to a position or said towing vehicle;
receiving a second position from a second DGPS system corresponding to a position or said towed implement;
computing a corrected position for said towed implement; and
for each desired swath;
computing a desired track and cross track error computing a steering correction for said towed implement; and
generating a first steering command to a first steering mechanism on said towed implement. - View Dependent Claims (9, 10, 11, 12, 13, 14)
