METHOD FOR MANAGING BRAKING IN A DEGRADED ADHESION CONDITION FOR A TRAIN

摘要

A method for managing braking in a degraded adhesion condition is described, comprising the steps of: - setting a target deceleration value (D_obb) that allows the train to reach a zero traveling speed in a target stopping distance (Dis_obb); - applying a non-degraded braking force (F_nd), the value of which allows the target deceleration value (D_obb) to be obtained; - verifying the presence of a degraded adhesion condition; - if no degraded adhesion condition is detected, maintaining the application of the non-degraded braking force (F_nd); - if a degraded adhesion condition is detected: - by means of sliding control means, ensuring that the braking means apply a degraded braking force (F_d); - activating recovery means arranged to positively influence the train deceleration; - determining a compensation deceleration value (D_comp); - applying a compensation braking force by means of at least one braking means and/or recovery means, so that the train reaches a zero traveling speed within the target stopping distance (Dis_obb).
