摘要

In the field of tractor/implement control, there is a need for accurate, real-time data on the true draught force generated by engagement of an implement (60) with the ground. A method of controlling a tractor/implement combination (10) includes obtaining and storing calibration data on the torque generated at the tractor flywheel, while the implement (60) is disengaged from the ground. Such data includes the rolling resistance and frictional/parasitic losses between the flywheel and driven wheel axle of the tractor. During subsequent operation of the tractor/implement combination, the calibration data are subtracted from instantaneous torque data to generate a signal indicative of the implement draught force. The draught force signal may be factored to take account of the tractor powertrain ratio and the rolling radius of the tractor tyres. The method allows generation of accurate draught force data, regardless of the nature and mounting location of the implement (60).
