Claim 7:
8. A brake management system, comprising:
one or more processors configured to set a target deceleration value to be reached by a vehicle system comprising at least one vehicle, the target deceleration value allowing the vehicle system to reach a zero traveling speed within a target stopping distance and within a first time, the one or more processors configured to direct at least one braking system of the vehicle system to apply a non-degraded braking force, a value of the non-degraded braking force calculated to obtain the target deceleration value, the one or more processors configured to check a presence of a degraded adhesion condition between the vehicle system and a route along which the vehicle system moves, wherein:
responsive to the degraded adhesion condition not being detected, the one or more processors are configured to direct the at least one braking system to maintain application of the non-degraded braking force, 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
responsive to the degraded adhesion condition being detected, the one or more processors are configured to direct the at least one braking system to:
apply a degraded braking force with the 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;
activate a recovery means arranged to control deceleration of the vehicle system, the recover means 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;
determine 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, the compensation deceleration value being arranged to allow the vehicle system to reach a zero traveling speed within the target stopping distance; and
apply at least one of the braking system or the recovery means to control one or more of the deceleration of the vehicle system or a compensation braking force, 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.
