    摘要： The present invention provides a method for determining ethanol thresholds for a flexible fuel control system for a motor vehicle capable of operating on more than one type of fuel. Preferably, the ethanol threshold is determined from an off-idle purge-free cell from a matrix of fuel adaptive memory cells normally used to compensate for car-to-car variations in required fueling. The ethanol threshold is periodically reduced to compensate for levels of alcohol creep indicated by the amount of purge-free adaptive memory elevation. If the learned value of percent alcohol content of the fuel is less than the ethanol threshold, gasoline operating parameters are implemented for the internal combustion engine. The off-idle purge-free cell also provides a basis for interpolating an on-board diagnostic (OBDII) ethanol threshold. As such, the OBDII monitors are only enabled if the learned value of percent alcohol content of the fuel is less than the OBDII ethanol threshold.

    摘要： A vehicle controller adjusts fuel delivered to an engine to compensate for an unknown fuel type being added to a fuel tank in a flexible fueled vehicle. The controller fuels a first set of engine cylinders according to first fueling scheme. For example, the controller fuels the first set assuming that E85 fuel was added to the fuel tank. The controller fuels a second set of engine cylinders according to a second fueling scheme. For example, the controller fuels the second set assuming that E0 fuel was added to the fuel tank. The controller continues to fuel the engine in this manner until an oxygen sensor becomes available. When the oxygen sensor becomes available, the vehicle controller may fuel the engine according to information from the oxygen sensor.

    摘要： A method for controlling a clutch for an air conditioner compressor having an armature and a rotor separated by an air gap width powered by an internal combustion engine having a crankshaft includes the steps of receiving a signal to engage the clutch, moving the armature to the rotor over a predetermined time to reduce the air gap width to zero, measuring rotational acceleration of the crankshaft of the internal combustion engine, and changing the predetermined time to reduce the air gap width to zero such that subsequent movement of the armature reduces the changes in the rotational acceleration of the crankshaft.

    摘要： A method of reducing vehicle component loading variations on an internal combustion engine in a motor vehicle includes the step of receiving a request to actuate a vehicle component and modifying a spark timing sequence for each spark plug of the internal combustion engine. The method also includes the step of actuating said vehicle component. The method further includes opposing a vehicle component torque generated by said actuation of said vehicle component with an adjustment of the internal combustion engine torque by reverting said modification of said spark timing sequence of each spark plug of the internal combustion engine.

    摘要： A spark control method for a vehicle engine is provided for enhancing engine performance and fuel economy prior to a fully warm state. The spark control method is based on coolant temperature and engine speed while accounting for an engine position and time from the start-to-run transfer. More particularly, the methodology of the present invention initially determines if the desired spark advance is before top dead center and if the throttle is open. If so, the methodology loads engine speed and coolant temperature to the engine control unit and interpolates a spark advance multiplier value. Thereafter, the current engine position pulse is loaded and an engine position pulse multiplier is interpolated and applied to the spark advance multiplier value. Next, the time since the start-to-run transfer is loaded and a time since start-to-run transfer multiplier is interpolated and applied to the spark advance multiplier value. Finally, the spark is advanced via the spark advance multiplier value, as adjusted by the engine position pulse multiplier and the time since start-to-run transfer multiplier. Upon engine operation reaching an after top dead center condition or when the throttle is closed, the methodology of the present invention is exited and engine operation is returned to normal spark control.
