Abstract: A system is configured to store a relationship data set of a plurality of diagnostic estimators and a plurality of failure modes, each failure mode represents a type of failure that can occur with a sensor or a vehicle component of a vehicle system, each diagnostic estimator is associated with a respective subset of the failure modes, each subset defines a control space within the vehicle system that contains at least one of (i) one or more sensors or (ii) one or more vehicle components. The system is configured to store a healthy diagnostic vector regarding nominal operational parameters of the vehicle system; acquire diagnostic information regarding current operational parameters of the vehicle system to generate an error diagnostic vector; apply the error diagnostic vector to the healthy diagnostic vector to generate a ratio diagnostic vector; and apply the ratio diagnostic vector to generate a value for each failure mode.

Abstract: A computing system is structured to receive operating data provided by a telematics circuit associated with a remote engine. The operating data comprises information provided by at least one sensor and/or at least one actuation command. The computing system is structured to determine, based on the operating data, a plurality of field-replaceable units (FRUs) associated with the operating data. The computing system is structured to generate a computer-based simulation corresponding to at least one degradation level for an FRU from the plurality of FRUs, identify a most probable failure, and rank the computer-based simulations across the plurality of FRUs. The computing system is structured to generate an electronic notification comprising data associated with the most probable failure and transmit the electronic notification to a computing device.

Abstract: A system includes a controller having a control signal generation unit that provides control signals to actuate one or more valve actuators of an engine to a desired position, and control signals to modify one or more operational parameters and an operational mode of the engine. A parameter signal process unit receives parameter signals corresponding to at least one operational parameter of the engine, and at least one sensor coupled to the engine. At least one sensor corresponds to a position of a valve. A failure detection unit generates at least one fault code corresponding to one or more failure modes. A failure mode isolation unit isolates a failure mode from the one or more failure modes in response to modifying the operational parameters or the operational mode, causing actuation of the valves to a desired position, or receiving the parameter signals and the sensor.
