Abstract
A method for determining a torque acting at a position of a drive train of an agricultural towing vehicle, includes controlling a clutch of the drive train between a closed state and an open state, capturing a drive-side rotational speed at the clutch via a first rotational speed sensor, capturing an output-side rotational speed at the clutch via a second rotational speed sensor, controlling the clutch in the direction of the open state, determining, during controlling the clutch, a difference between the rotational speeds on the drive and output sides, comparing the difference with a predetermined difference limit value, capturing the value of a physical variable that causes the clutch control on the basis of the comparison result, and determining the torque on the basis of the captured value of the physical variable.
