Claim 0:
1. A method comprising:
setting a target deceleration value to be reached by a vehicle system comprising at least one vehicle, the target deceleration value set using one or more processors of a brake management system, the target deceleration value set to allow the vehicle system to reach a zero traveling speed within a target stopping distance and within a first time;
applying a non-degraded braking force using at least one braking system of the vehicle system, a value of the non-degraded braking force calculated by the one or more processors of the brake management system to obtain the target deceleration value;
checking a presence of a degraded adhesion condition between the vehicle system and a route along which the vehicle system moves using the one or more processors of the brake management system; and one or more of:
(a) responsive to the degraded adhesion condition not being detected, maintaining application of the non-degraded braking force with the at least one braking system of the vehicle system, which will allow the vehicle system to reach the target deceleration value within a first time and allow the vehicle system to achieve accordingly a zero traveling speed within the target stopping distance; or
(b) responsive to the degraded adhesion condition being detected:
applying a degraded braking force with the at least one braking system that is lower than the non-degraded braking force and coinciding with an upper limit braking force based on the degraded adhesion condition;
activating a rail vehicle sandbox, a magnetic shoe, a magnetic track brake, or an eddy current brake to control deceleration of the vehicle system using the one or more processors of the brake management system, the rail vehicle sandbox, the magnetic shoe, the magnetic track brake, or the eddy current brake allowing the vehicle system to reach the target deceleration value within a second time that is greater than the first time to allow the vehicle system to reach a zero traveling speed within a degraded stopping distance that is greater than the target stopping distance;
determining a compensation deceleration value as a function of the degraded stopping distance based on one or more difference between the degraded braking force and the non-degraded braking force using the one or more processors of the brake management system, the compensation deceleration value being arranged by the one or more processors of the brake management system to allow the vehicle system to reach a zero traveling speed within the target stopping distance; and
applying at least one of: the at least one braking system or the rail vehicle sandbox, the magnetic shoe, the magnetic track brake, or the eddy current brake to control one or more of the deceleration of the vehicle system or a compensation braking force using the one or more processors of the brake management system, the compensation braking force being greater than the non-degraded braking force and based on the compensation deceleration value, to the compensation braking force allowing the vehicle system to reach the compensation deceleration value and to reach the zero traveling speed within the target stopping distance.
