A method for controlling and recovering the adhesion, during a slipping phase, of wheels (Wi) belonging to at least two controlled axles (Ai) of a railway vehicle, comprising the steps of: generating speed signals indicative of the angular speed (ωi) of said wheels (Wi); estimating the value of the instantaneous adhesion (μ(Tj)) at the point of contact of such wheels (Wi) and the rails, using an adhesion observer; generating a target-slip value (δ) for the wheels (Wi) of the controlled axles (Ai) by means of an optimization algorithm which processes the estimated adhesion values (μi(Tj)), and modifying the target-slip value continuously in time, with a predetermined sampling period, such as to maximize the average value of the adhesion of the wheels of the vehicle.
