摘要： A method of controlling an electro-actuated clutch in an internal combustion engine, the clutch including a clutch mechanism, an electric motor for actuating the clutch mechanism, and a mechanical transmission, which is interposed between the electric motor and the clutch mechanism. During a manufacturing phase of the system, a detachable connection is established in the mechanical transmission, wherein a first element simply rests on a second element to divide the electro-actuated clutch into a first part, arranged upstream of the detachable connection, and a second part, arranged downstream of the detachable connection. During operation, a first position signal generated by a first position sensor mechanically connected to a point of the first portion of the electro-actuated clutch is read, as is a second position signal generated by a second position sensor mechanically connected to a point of the second portion of the electro-actuated clutch. The first position signal is compared with the second position signal. A position in which the first position signal starts differing from the second position signal is recognized, and an estimate made of a closing position of the clutch mechanism coinciding with the position in which the first position signal starts differing from the second position signal.
