Systems and method of determining PTO transmission gear ratio

A system, comprising:

• a sensor configured to sense a parameter indicative of a power take-off (PTO) shaft speed;
• a controller comprising:
• communication circuitry configured to receive a first shaft speed;
• a processor configured to determine a PTO shaft acceleration by monitoring the parameter indicative of the PTO shaft speed over time;
• and
• a plurality of estimators, wherein each of the plurality of estimators is assigned one of a plurality of known PTO transmission gear ratio options, and wherein each estimator is configured to determine a normalized PTO clutch gear ratio based, at least in part, on the first shaft speed, the PTO shaft speed, and the PTO transmission gear ratio assigned to the estimator;
• wherein the controller is configured to select the estimator of the plurality of estimators outputting the normalized PTO clutch gear ratio closest to 1 when the PTO shaft acceleration drops below a threshold value,
• wherein the controller is configured to control a PTO clutch based, at least in part, on the known PTO transmission gear ratio assigned to the selected estimator of the plurality of estimators.

A non-transitory computer readable medium comprising executable instructions that when executed cause a processor to:

• determine a PTO shaft acceleration by monitoring a received parameter indicative of a power take-off (PTO) shaft speed over time;
• determine a plurality of normalized PTO clutch gear ratios, wherein each of the plurality of normalized PTO clutch gear ratios is determined based, at least in part, on a drive shaft speed, the PTO shaft speed, and one of a plurality of known PTO transmission gear ratio options;
• select one of the plurality of normalized PTO clutch gear ratios, when the PTO shaft acceleration drops below a threshold value, wherein the normalized PTO clutch gear ratio that is closest to 1 is selected;
• and
• control a PTO clutch based, at least in part, on the known PTO transmission gear ratio associated with the selected normalized PTO clutch gear ratio.
