Method of controlling an electro-actuated clutch for determining the closing position

Abstract

A method of controlling an electro-actuated clutch in an internal combustion engine, which clutch is provided with 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; the method includes the steps of establishing, during a manufacturing phase of the system, a detachable connection 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; reading a first position signal generated by a first position sensor mechanically connected to a point of the first portion of the electro-actuated clutch; reading a second position signal generated by a second position sensor mechanically connected to a point of the second portion of the electro-actuated clutch; 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 coinciding with the position in which the first position signal starts differing from the second position signal.
