Patent number: 6144910Abstract: In the field of agricultural tractor and implement combinations, there have been numerous attempts at improving the efficiency of isolated sub-systems such as the engine, the implement control and the transmission. Such sub-systems have individually successfully been automated, but previous attempts to automate the entire control of a tractor during eg. plowing operations have previously failed. Accordingly, a control apparatus has been provided for a tractor/implement combination to include a control apparatus comprising a plurality of microprocessors. The microprocessors are arranged in a hierarchical control strategy that includes a steady state reference model of various performance parameters of the tractor/implement combination.Type: GrantFiled: October 10, 1997Date of Patent: November 7, 2000Assignee: New Holland North America, Inc.Inventors: Andrew James Scarlett, John Charles Lowe
