According the present invention, the requested torque Tq demand is controlled at least based on a current value Tq fw_pres for the dynamic torque, a moment of inertia J for the powertrain, a desired derivative Tq fw_req of the dynamic torque related to a spring constant k for the powertrain; T Ù ¢ q f ¢ w _ r ¢ e ¢ q k ; a current rotational difference É pres between a first rotational speed É 1 for a first end of the powertrain and a second rotational speed É 2 for a second end of the powertrain, and a calibration parameter Ä cal related to a transient for the dynamic torque in the direction of the desired derivative Tq fw_req , wherein the current rotational speed difference É pres is minimised.",
