Abstract

A system and method for managing braking in a degraded adhesion condition for a vehicle system including at least one vehicle comprising setting a target deceleration value, applying a non-degraded braking force via a braking system of the vehicle system, detecting a presence of a degraded adhesion condition between the vehicle system and a route along which the vehicle system moves. Responsive to the degraded adhesion condition not being detected, maintaining the application of the non-degraded braking force, or responsive to the degraded adhesion condition being detected, applying a degraded braking force, activating recovery means to control deceleration of the vehicle system, determining a compensation deceleration value, and applying at least one of the braking system or recovery means to control the deceleration of the vehicle system.
