Abstract
Method and apparatus for compensating for transient effects in pneumatically operated air brake system for a railway vehicle. A look up table or experimentally determined second order correction values is stored in a memory. Based on the magnitude of a previous application of the brakes, a correction value is selected from the look up table having a magnitude to compensate for transient errors in the system. The correction value is then diminished by fixed decrements at fixed intervals. Upon a subsequent application of the brakes, the diminished correction value is used to adjust the pressure communicated to braking mechanisms located on the train cars.
