Patent ID: 8224591

Claim:
A system comprising: a control subsystem configured to control at least one of braking or traction operations of a vehicle system that includes a first powered unit and a second powered unit that is remote from the first powered unit, each of the first and second powered units configured to provide a tractive effort to propel the vehicle system; and a comparator subsystem configured to evaluate a difference between a first pressure reading received from a first transducer that is part of a braking system on the first powered unit and a second pressure reading received from a second transducer that is part of a braking system on the second powered unit, wherein the comparator subsystem is configured to determine the difference in the first and second pressure readings when the first powered unit and the second powered unit are operating in a distributed power application of the vehicle system, and wherein at least one of the comparator subsystem or the control subsystem is configured to determine that the second pressure reading is invalid based on the difference in the first and second pressure readings.
