a step of comparing the real RADAR image and the simulated RADAR image; and
a step of correcting the estimated position of the vehicle as a function of a result of the comparing,
wherein the acquiring, elaborating, and comparing steps are repeated at successive time steps with different estimated positions of the vehicle,
wherein, at the correcting step during a first time step of the successive time steps, defining a pool of uncertainty corresponding to a zone in which the vehicle is located,
wherein, during a second time step of the successive time steps, the acquiring step is repeated using a plurality of estimated positions of the vehicle located within the pool of uncertainty, and
