Electric brake control system and method for railroad car

摘要

A microprocessor based brake control system for a railroad car, wherein the car brake cylinder pressure is regulated in accordance with the specific design net braking ratio of the car and the actual car load weight in order to achieve consistent levels of retardation on the cars throughout the length of a train irrespective of such variables as design net braking ratio that otherwise influence car retardation. The actual level of retardation is increased on partially loaded or empty cars so that those cars share in the braking of a train. This is especially useful during grade braking.
