SYSTEMS AND METHOD OF DETERMINING PTO TRANSMISSION GEAR RATIO

A method includes receiving a first shaft (16) speed, measuring a parameter indicative of a PTO shaft (20) speed, determining a PTO shaft (20) acceleration by monitoring the parameter indicative of the PTO shaft (20) speed over time, determining, via a plurality of estimators (262), a plurality of n...

Zusammenfassung:	A method includes receiving a first shaft (16) speed, measuring a parameter indicative of a PTO shaft (20) speed, determining a PTO shaft (20) acceleration by monitoring the parameter indicative of the PTO shaft (20) speed over time, determining, via a plurality of estimators (262), a plurality of normalized PTO clutch (60) gear ratios, wherein each of the plurality of estimators (262) determines one of the plurality of normalized PTO clutch (60) gear ratios based, at least in part, on the first shaft (16) speed, the PTO shaft (20) speed, and one of a plurality of known PTO transmission gear ratio options, and selecting one of the plurality of estimators (262), when the PTO shaft (20) acceleration drops below a threshold value, wherein the normalized PTO clutch (60) gear ratio determined by the selected estimator is about 1.
