Abstract:
The invention is related to a method for controlling the rotational speed of an engine operating as the power source of a work machine, preferably an agricultural harvester, wherein a change in the load required from the engine during operation of the machine results in the controlled change of the engine speed towards a target value defined by a control curve, wherein the controlled change takes place according to one of a plurality of active control characteristics, depending on the degree of change in the engine speed detected as a direct consequence of the load change. A faster or slower speed change may for example be selected, and/or the target value may be continuously updated. According to a further embodiment, the control curve is referenced to the crop load, being the part of the load related to crop processing. The invention is related also to a machine equipped with a control mechanism configured to implement the method of the invention.

Claim (Index 10):
A method for controlling the rotational speed of an engine that operates as the power source of a work machine, the method comprising the steps of:\n obtaining a measured value representative of a load of the engine; obtaining a measured value of a rotational speed of the engine; deriving from a pre-defined control curve, a target value for the engine speed as a function of the measured engine load value or a portion thereof; if the measured speed differs from the target value, changing the engine speed towards the target value, according to an active control characteristic wherein: the pre-defined control curve comprises a first portion where the target speed is constant at a first value, a second portion where the target speed is constant at a second value higher than the first, and a third portion where the target speed is an increasing function of the measured load, increasing from the first to the second value, and the operator of the machine can select from at least two of said pre-defined control curves, the second control curve operating between first and second speeds that are higher than the first and second speed of the first control curve, and wherein according to the second control curve, the target speed decreases less rapidly in the third portion of the curve than according to the first control curve.
