Abstract
An agricultural system including an agricultural baler and a control unit. The agricultural baler includes a baler driveline; a rotatable flywheel; and a rotary input shaft connected by way of the baler driveline to the rotatable flywheel. The driveline includes one or more clutches for controllably transferring rotary drive between the input shaft and the flywheel. The control unit is configured to receive input-power-data indicative of a drive power available at the rotary input shaft; and determine a clutch-control-signal for controlling an amount of torque transferred from the input shaft to the flywheel bye the one or more clutches, based on the input-power-data.
Claims15
An agricultural system comprising:
- an agricultural baler comprising:
- a baler driveline;
- a rotatable flywheel;
- and
- a rotary input shaft connected by way of the baler driveline to the rotatable flywheel, the driveline including one or more clutches for controllably transferring rotary drive between the input shaft and the flywheel;
- and
- a control unit that:
- receives input-power-data indicative of a drive power available at the rotary input shaft, wherein the input-power-data comprises measured-input-power-data that represents measurements of one or more operating parameters of the agricultural system or an associated tractor;
- determines a clutch-control-signal for controlling an amount of torque transferred from the input shaft to the flywheel by the one or more clutches, based on the input-power-data;
- determines an error-factor that is an indicator that one or more of the measurements has dropped below an expected value;
- determines a clutch-control-signal for decreasing a rate at which torque is transferred to the flywheel by the one or more clutches based on the error-factor;
- and
- controls the one or more clutches based on the clutch-control-signals to set a pressure applied to engage friction surfaces of the one or more clutches.
An agricultural system comprising:
- an agricultural baler comprising:
- a baler driveline;
- a rotatable flywheel;
- and
- a rotary input shaft connected by way of the baler driveline to the rotatable flywheel, the driveline including one or more clutches for controllably transferring rotary drive between the input shaft and the flywheel;
- and
- a control unit that:
- receives input-power-data indicative of a drive power available at the rotary input shaft;
- determines a clutch-control-signal for controlling an amount of torque transferred from the input shaft to the flywheel by the one or more clutches, based on the input-power-data;
- and
- controls the one or more clutches based on the clutch-control-signal to set a pressure applied to engage friction surfaces of the one or more clutches,
- wherein the input-power-data comprises predefined-input-power-data, wherein the predefined-input-power-data is provided by an operator, and wherein the control unit is configured to select a high-responsive target-control-profile if the operator does not provide the predefined input-power-data before a rotational speed of the rotary input shaft exceeds a set speed-threshold.
A computer-implemented method for controlling an agricultural baler, the baler comprising a baler driveline;
- a rotatable flywheel;
- and a rotary input shaft connected by way of the baler driveline to the rotatable flywheel, the driveline including one or more clutches for controllably transferring rotary drive between the input shaft and the flywheel,
- wherein the method comprises:
- receiving input-power-data indicative of a drive power available at the rotary input shaft, wherein the input-power-data comprises measured-input-power-data that represents measurements of one or more operating parameters of the agricultural system or an associated tractor;
- determining a clutch-control-signal for controlling an amount of torque transferred from the input shaft to the flywheel by the one or more clutches, based on the input-power-data;
- determining an error-factor that is an indicator that one or more of the measurements has dropped below an expected value;
- determining a clutch-control-signal for decreasing a rate at which torque is transferred to the flywheel by the one or more clutches based on the error-factor;
- and
- controlling the one or more clutches based on the clutch-control-signals to set a pressure applied to engage friction surfaces of the one or more clutches.
