1. A method of disengaging a clutching device, the method comprising:
sweeping an output torque of an electric motor drivingly connected to the clutching device such that a torque transmitted by the clutching device vanishes at least temporarily during the sweep, and
disengaging the clutching device during the sweep;
wherein the output torque of the electric motor is reduced to zero when or once an acceleration of the electric motor following disengagement of the clutching device exceeds a predetermined threshold.
