Reducing nuisance fault indications from a vehicle using physics based and data driven models

摘要

An off-board apparatus is provided for reducing nuisance fault indications from a vehicle. The apparatus is communicably coupled to a vehicle health monitoring (VHM) system, or one or more vehicle systems for at least collecting and communicating data thereto such as data that indicates fault generated by a line replaceable unit of the vehicle in response to a built-in test. The apparatus is also coupleable with a computerized maintenance management system configured to store data that describes a historical condition and maintenance of the vehicle. The apparatus is programmed to determine a probability of validity or invalidity of the fault indication, determine a condition indicator for the signal path based on the LRUs current and historical operational environment, and generate a notification, or output the fault indication for generation of a notification, only in an instance in which the fault indication, with a high probability is valid.
