Abstract

See full text

Method and device for estimating the position of an actuator body in an electromagnetic actuator to control a valve of an engine, according to which the actuator body, which is at least partly made of ferromagnetic material, is displaced towards at least one electromagnet, by the effect of the force of electromagnetic attraction generated by the electromagnet itself; the position of the actuator body relative to the electromagnet is determined on the basis of the value assumed by the reluctance of a magnetic circuit constituted by the electromagnet and by the actuator body.
