Abstract: A method and system for diagnosing battery system problems in a vehicle, where the method distinguishes between problems of various battery system components. More particularly, battery connection problems such as loose connections, corroded battery terminals, etc., may be distinguished from battery system problems as a whole. Load related readings that generally reflect the performance of the battery system during a cranking event and one or more non-load related readings may be gathered and used to determine whether there is a battery system problem and whether there is a battery specific problem. If load related readings and/or non-load related readings fail to indicate a battery specific problem, a battery connection problem may be diagnosed.

Abstract: A method and system are provided for controlling a vehicle capable of operating in a fuel economy mode in which fuel is conserved by limiting operation of an engine. The method includes obtaining forecast temperatures for one or more dates and comparing the forecast temperature for each date to a threshold temperature. The method further includes generating a control signal if the forecast temperature for a given date meets a predetermined condition relative to the threshold temperature. The control signal is configured to disable fuel economy mode of the vehicle. The method further includes disabling the fuel economy mode of the vehicle in response to receiving the control signal. By disabling fuel economy mode at selected temperatures, the method and system allow the vehicle to preserve a sufficient state of charge in the vehicle battery for cold starts.

Abstract: Methods and systems for monitoring no start events for vehicles are provided. In accordance with one embodiment, a vehicle includes an engine, a sensing unit, a processor, and a transmitter. The sensing unit is configured to measure one or more parameter values for a vehicle after a request has been made to start the engine. The processor is coupled to the sensing unit, and configured to determine when a no start event has occurred for the vehicle using the one or more parameter values. The transmitter is coupled to the processor, and is configured to transmit, to a remote server, a no start event history for the vehicle based on the determining by the processor.
