SYSTEM AND METHOD FOR CONTROLLING THE ENGAGEMENT OF A PTO CLUTCH FOR A WORK VEHICLE

A method for controlling the engagement of a power take-off (PTO) clutch of a work vehicle may generally include implementing one or more recovery actions to prevent the clutch from being damaged and/or to prevent the vehicle's engine from stalling. For instance, an energy-related recovery acti...

Zusammenfassung:	A method for controlling the engagement of a power take-off (PTO) clutch of a work vehicle may generally include implementing one or more recovery actions to prevent the clutch from being damaged and/or to prevent the vehicle's engine from stalling. For instance, an energy-related recovery action may be implemented when an estimated clutch energy transmitted through the PTO clutch is greater than or equal to a maximum allowable clutch energy associated with the clutch. In addition, or as an alternative thereto, a stall-related recovery action may be implemented when the engine speed is less than or equal to a predetermined engine stall speed and the speed deceleration rate for the engine is greater than or equal to a predetermined deceleration rate threshold.
