Abstract: A method for monitoring the starter motor includes determining starter motor resistance associated with an engine starting event and determining a back-emf for the starter motor based upon the starter motor resistance. A state of health of the starter motor corresponding to the back-emf of the starter motor and engine cranking time is determined. Engine stop/start functionality is controlled based upon the state of health of the starter motor.

Abstract: A method for detecting and locating an open-wire fault within a vehicle subsystem, is provided. The method compares an output voltage of a low-pass filter circuit of the vehicle subsystem to a threshold voltage; detects that an open-wire fault exists in the vehicle subsystem when the output voltage is not less than the threshold voltage; determines a capacitance value of the low-pass filter circuit; and performs a lookup, using the capacitance value, to determine the location of the detected open wire fault.

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: A vehicle includes a plurality of subsystems that are monitored during on-going operation. A method for monitoring a subsystem includes monitoring states of commanded and observed parameters for the subsystem. Deviations in the observed parameters are determined off-board the vehicle. The deviations are employed to determine magnitudes of subsystem operating signatures off-board the vehicle. The subsystem operating signatures are employed to identify presence of a subsystem fault and isolate the subsystem fault off-board the vehicle. The presence of the isolated fault is communicated to the vehicle.

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.
