摘要： Methods and systems are provided for improving engine startability during cold-start conditions, when operating with gasoline fuels, alcohol fuels, or blended fuels. In one example, a method of engine cold-start control may include initiating fuel injection for cylinder combustion with manifold pressure lowered via intake throttle adjustments. The manifold pressure is lowered based on an optimization between cylinder charge reduction and improved fuel boiling at the lower pressure.

摘要： Systems and methods for operating a transmission of a hybrid vehicle's driveline are presented. In one example, the systems and methods estimate a driveline disconnect clutch stroke pressure and gain via extending a line from a non-zero driveline disconnect clutch torque capacity to a zero driveline disconnect clutch torque capacity.

摘要： Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

摘要： Systems and methods for restarting an engine are presented. In one example, an engine may be automatically stopped and started in response to thresholds that may be adjusted as a distance traveled by the vehicle increases. The thresholds may be adjusted responsive to useful life consumed of devices that may participate in automatic engine starting and stopping.

摘要： Systems and methods for supplying electrical power to two electrical buses that operate at different voltages are disclosed. In one example, two or more switches are selectively opened and closed to electrically couple and decouple a first alternator and a second alternator from the respective buses. The switches may be operated in response to state of battery charge or electrical load demand on the two electrical buses.

摘要： Systems and methods for shifting a transmission of a hybrid driveline that include a torque converter with a lockup clutch are presented. The systems and methods may adjust a feedforward motor torque command to match application of motor torque to a time that a gear clutch closes so that shifting may be improved and so that driveline torque disturbances may be less noticeable.
