Abstract
A rotational monitoring system of at least one axle designed to identify at least one axle controlled by it having an estimated instantaneous linear speed lower than a predetermined instantaneous linear limit speed, and remove the braking force to one or more wheels of the axle identified to have an estimated instantaneous linear speed lower than the predetermined instantaneous linear limit speed, by canceling a pressure to brake cylinders associated with the at least one axle identified to have an estimated instantaneous linear speed lower than the predetermined instantaneous linear limit speed. The cancellation of a pressure is obtained by acting on an electro-pneumatic valve designed to perform a Remote Release function associated with the pneumatic circuits generating braking pressure for the brake cylinders and adapted to cancel a residual braking pressure.
