    摘要： Methods, program products, hybrid, and non-hybrid vehicles are provided for providing diagnostics for a direct current (DC) converter of the hybrid, and non-hybrid vehicle. The vehicle includes an engine, a rechargeable energy storage system (RESS), the direct current (DC) converter, and a controller. The engine is automatically turned on and off based on driver inputs in accordance with an auto-stop feature. The RESS at least facilitates turning on the engine. The DC converter is coupled to the RESS. The controller is coupled to the DC converter, and is configured to determine a status of the engine, receive a DC converter voltage value from the DC converter, and provide diagnostics for the DC converter based on the engine status, RESS voltage, and the DC converter voltage.

    摘要： Methods, program products, and vehicles are provided for providing diagnostics for a smart sensor, such as a direct current (DC) converter, for a vehicle. A result of a diagnostic test is received from the smart sensor at a first time. A sequence indicator is retrieved from memory. The sequence indicator pertains to a second time in which the diagnostic test is expected to be completed by the smart sensor. A health assessment is provided using the result via a processor, provided that the second time does not precede the first time. The health assessments may be linked individually to a diagnostic trouble code, or may be grouped together and linked as a group to a diagnostic trouble code. Multiple smart sensor health assessments may be grouped and linked to diagnostic trouble codes.

    摘要： A method for isolating voltage sensor errors from contactor errors in an electrical system includes measuring a voltage between ground and a voltage bus rail when a contactor is open, and comparing the measured voltage to a first threshold voltage corresponding to a calibrated voltage reading that is expected when the contactor is closed. A first diagnostic code is recorded with a stuck-in-range status for the sensor when the measured voltage is greater than 0 and less than the first threshold voltage. A second diagnostic code is recorded with a stuck-closed status for the contactor when the measured voltage is equal to the first threshold voltage. The measured voltage may be compared to a second threshold voltage that exceeds the first threshold voltage, with a third diagnostic code recorded with a shorted value for the sensor when the measured voltage exceeds the first threshold voltage or is less than 0.

    摘要： A motor vehicle engine includes an operator controlled fuel injection enabling switch effective to disconnect electric fuel injection apparatus from an electric power source and thus initiate the cessation of engine operation when deactivated. However, the spark ignition system is still powered through an oil pressure switch so as to continue engine operation for a few extra crankshaft rotations to reduce the unburned fuel in the intake passage as the engine stops and thus reduce throttle bore coking. In a vehicle having a fuel pump relay activated by the fuel injection enabling switch with contacts connected across the oil pressure switch, the invention may be obtained by changing the power connection of the spark ignition system from the fuel injection enabling (ignition) switch to the fuel pump relay.

    摘要： In accordance with exemplary embodiments, battery capacity of an electric vehicle can be automatically determined. In an exemplary method, an instruction is received to determine a battery capacity value and one or more vehicle accessories are activated to discharge the battery to a first charge level. When the first charge level is reached, a generator in the vehicle is started and used to charge the battery to a second charge level, after which the battery capacity value can be determined and stored. In accordance with the exemplary embodiments, the vehicle comprises a controller adapted to cause a battery to be discharged and charged to determine a capacity value of the battery. A plurality of accessories are configured to activate and deactivate responsive to the controller to discharge the battery, while a generator is responsive to the controller to charge the battery so that the controller can determine the battery capacity value.
