    Abstract: A system and method for converting a vehicle steering angle command to a vehicle steering torque command for a vehicle steering system in a vehicle. The method estimates a self-aligning torque that defines the torque that maintains a vehicle steering wheel at a neutral steering position or to a position that makes no slip angle at the road wheel, applies known total steering torque commands to the steering system at a plurality of sample time steps where the known steering torque commands include the self-aligning torque, and measures a vehicle steering angle at each time step. The method then models the steering system of the vehicle using the torque commands, the measured steering angles, a system delay and a plurality of unknown parameters.

    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.

    Abstract: A distributed vehicle health management system includes a vehicle-based diagnostic processor executing diagnostic routines in a vehicle. The diagnostic routines generate diagnostic data. A processor-based device executes advanced vehicle health management routines. The processor-based device determines a state of health of a component as a function of the diagnostic data. A telematics device communicates at least one of state of health data and diagnostic data from the vehicle. A remote entity disposed remotely from the vehicle. The remote entity receives data via the telematics device, the data being a selective subset of data output from at least one of the vehicle-based processor and processor-based device. The remote entity executes calibration routines as a function of the data received by the vehicle for calibrating at least one of the diagnostic routines and health management routines.

    Abstract: An internal combustion engine including a starter is shown. A method for monitoring the starter includes determining electrical energy consumed by pinion and motor solenoids operative to activate and rotate a pinion gear of an electrically-powered motor meshingly engageable to a starter ring gear portion of a flywheel of the engine during an engine starting event. Current ringing in the pinion and motor solenoids is monitored during the engine starting even, and a fault is identified in the pinion and motor solenoids based upon the current ringing and the electrical energy consumption of the starter during the engine starting event.

    Abstract: Methods and systems are provided for vehicular communications. The systems include a server and a controller in a vehicle. The controller is configured to receive data from vehicular components and transmit the data to the remote server. In a normal mode, the data is transmitted in accordance with a normal frequency of events, while in an abnormal mode, the data is transmitted in accordance with an abnormal frequency of events. The abnormal frequency is different from the normal frequency. The abnormal mode is set in response to an event trigger denoting a fault of at least one component.

    Abstract: A method proactively transitions performance of a functional operation from a primary subsystem to a secondary subsystem within a vehicle or other system having an electronic control unit (ECU). The method includes receiving health management information via the ECU when the primary subsystem is actively performing the functional operation within the system and the secondary subsystem operates in a standby mode, wherein the health information is indicative of a numeric state of health (SOH) of the primary subsystem. The method also includes comparing the numeric SOH to a calibrated non-zero threshold SOH, and then commanding, via the ECU, a transition of the performance of the functional operation to the secondary subsystem and placing the primary subsystem in the standby mode when the numeric SOH is less than the calibrated non-zero threshold SOH. A vehicle executes the method via the ECU.
