Method and apparatus for on-board/off-board fault detection
Abstract:
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.
