Abstract
A method for controlling engagement of a power take-off (PTO) clutch may include transmitting a PTO control command for initiating engagement of the PTO clutch, determining that an output speed for the PTO clutch has not increased within a predetermined time period following the transmission of the PTO control command, and determining an average engine pre-load for the work vehicle over a time period occurring prior to transmission of the PTO control command. Moreover, in response to determining that the output speed for the PTO clutch has not increased within the predetermined time period, the method may include transmitting a speed control command associated with increasing a requested engine speed for the work vehicle, determining an adaptive torque command for controlling the engagement of the PTO clutch as a function of the average engine-pre-load, and controlling the engagement of the PTO clutch based on the adaptive torque command.
