SYSTEM AND METHOD FOR DETERMINING A BRAKE APPLICATION LEVEL OF A TRAIN DURING A COMMUNICATION LOSS•

摘要

pIn a railroad train having a brake system including a fluid carrying brake pipe ( 14 ) having an exhaust ( 52 ) and connecting a lead locomotive ( 12 ) and at least one remote locomotive, the train further comprising a communication system ( 24 ) for communicating between the lead locomotive and the remote locomotive, a method for adaptively determining a brake application for signaling a remote locomotive of a train during a communication loss includes determining a brake system operating condition of the train ( 72 ). The method also includes determining an operability condition of the communication system ( 74 ) and identifying an operator commanded brake application level at the lead locomotive during a communication system inoperability condition ( 76 ). The method further includes determining a signaling brake application level sufficient for signaling the remote locomotive via the brake pipe responsive to the monitored brake system operating condition ( 78 )./p[US2007241610A1]
