Abstract

A method for controlling the movement of a component that moves towards a position defined by a limit stop in an internal combustion engine; the control method comprises the steps of detecting, by means of at least one acoustic microphone, the intensity of the microphonic signal generated by the impact of the component against the limit stop; and determining the impact instant and/or the impact speed of the component against the limit stop by analyzing the intensity of the microphonic signal generated by the impact.
