Abstract
Official abstract text for this publication.
A method for monitoring a subsystem of a subject vehicle includes, in an off-board environment, executing a controller-based scheme. The scheme includes determining a plurality of residuals based upon expected and observed states of parameters associated with operation of the subsystem, determining a subsystem operating signature based upon the residuals, employing the subsystem operating signature to isolate a subsystem fault, and communicating the subsystem fault to an on-board controller of the subject vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for monitoring a subsystem of a subject vehicle, comprising: when an on-board algorithm detects unexpected behavior in the subsystem, communicating subsystem data to an off-board environment; in the off-board environment, executing a controller-based scheme comprising: determining a plurality of residuals based upon expected and observed states of parameters associated with operation of the subsystem; determining a subsystem operating sig…
