Patent ID: 8521447

Claim:
A method comprising: comparing a first brake pressure measured at a first transducer that is part of a braking system on a lead powered unit of a distributed power (DP) system to a second brake pressure measured at a second transducer that is part of a braking system on a remote powered unit of the DP system; and determining, using one or more processors, whether the second transducer is functioning within designated operational parameters when the DP system is operating in a DP mode based on comparing the first brake pressure to the second brake pressure, wherein determining, using the one or more processors, whether the second transducer is functioning within the designated operational parameters includes determining that the second brake pressure is invalid; wherein each of the lead and remote powered units is a separate and distinct powered unit capable of providing tractive efforts to the DP system, the lead and remote powered units being directly or indirectly coupled to each other.
