    • A method of controlling an electro-actuated clutch (1) in an internal combustion engine, which clutch is provided with a clutch mechanism (2), an electric motor (3) for actuating the clutch mechanism (2), and a mechanical transmission (4) which is interposed between the electric motor (3) and the clutch mechanism (2); the method includes the steps of establishing, during a manufacturing phase of the system, a detachable connection in the mechanical transmission (4), wherein a first element simply rests on a second element to divide the electro-actuated clutch (1) into a first part, arranged upstream of the detachable connection, and a second part arranged downstream of the detachable connection; reading a first position signal generated by a first position sensor (14) mechanically connected to a point of the first portion of the electro-actuated clutch (1); reading a second position signal generated by a second position sensor (22) mechanically connected to a point of the second portion of the electro-actuated clutch (1); comparing the first position signal with the second position signal; recognizing the position in which the first position signal starts differing from the second position signal; and estimating the closing position of the clutch mechanism (2) coinciding with the position in which the first position signal starts differing from the second position signal.
