A system (10) and method for automatically controlling braking of a train (38). The method includes applying a first degree of braking to the train during a first period of time, and then applying a second degree of braking to the train during a second time period following the first time period so that the train is slowed in a manner effective to limit a peak deceleration rate experienced by the train. The system includes a sensor (36) providing a signal indicative of an operating condition of a locomotive of the train requiring braking of the train, a memory (22) storing a braking schedule, and a processor (18) comprising logic executable for accessing the braking schedule stored in the memory responsive to the signal to automatically control braking of the locomotive according to the schedule.

La présente invention a trait à un système (10) et un procédé pour la commande automatique de freinage d'un train (38). Le procédé comprend l'application d'un premier degré de freinage au train pendant une première période de temps, et l'application d'un deuxième degré de freinage au train pendant une deuxième période de temps suivant la première période de temps de sorte que le train ralentisse de manière efficace pour limiter un taux de décélération de crête subi par le train. Le système comporte un capteur (6) fournissant un signal représentatif d'un régime d'une locomotive du train nécessitant le freinage du train, une mémoire (22) assurant le stockage d'un programme de freinage, et un processeur (18) comprenant une logique exécutable pour l'accès au freinage programmé dans la mémoire sensible au signal pour la commande de freinage automatique de la locomotive selon le programme.
