ON VEHICLE COMPRESSED AIR SYSTEM LEAK DETECTION

Abstract:

A system for detecting a compressed air system leak. The system includes a first air tank, a second air tank, a pressure sensor, and a controller communicatively coupled to at least one of the pressure sensor. The controller is structured to determine an identifiable event including a requested air use or an unrequested air use, determine a leak rate associated with the identifiable event, compare the leak rate to a leak threshold, and generate a command structured to indicate a compressed air system leak responsive to the leak rate exceeding the leak threshold.
