A method for approximately determining the torque actually transmitted by a clutch of a drive train of a vehicle, includes the steps of: setting a closed state of the clutch and transmitting a torque by way of the drive train, providing a state space model showing the drive train, particularly a Kalman filter, determining a torque which can theoretically be transmitted or is transmitted by the clutch in the closed state, and approximately determining the torque actually transmitted by the clutch, by adding the theoretically transmittable or transmitted torque and a disturbance torque determined by calculation, wherein the disturbance torque is determined on the basis of the state space model and actual rotational speeds of individual drive train components and/or of actual torques transmitted by individual drive train components.
