    摘要： An engine control system for an auto-stop/start vehicle, comprising: an actuator control module, a correction determination module, and a spark adjustment module. The actuator control module determines a target spark timing for a first time that is between a second time when engine cranking begins and a third time when a measured engine speed becomes greater than a predetermined engine speed after the second time. The correction determination module determines a spark timing correction for the first time based on a target engine speed and a measured engine speed. The spark adjustment module sets a spark timing for the first time based on the target spark timing and the spark timing correction.

    摘要： An engine control system for an auto-stop/start vehicle includes an auto-stop/start module and an actuator control module. The auto-stop/start module selectively generates an auto-stop command for shutting down an engine while an ignition is in an ON state. The actuator control module disables fuel to the engine when the auto-stop command is generated and closes a throttle valve to a predetermined throttle opening when the auto-stop command is generated.

    摘要： A vehicle includes a direct-start engine and a fuel rail with a threshold fuel pressure, a transmission having a threshold fluid pressure, and a fuel delivery system. The system has a controller, a motor having a shaft, and an integrated pump assembly including a high-pressure (HP) fuel pump and a low-pressure (LP) fluid pump each connected to the shaft. Threshold pressures are maintained during the predetermined engine state, which includes an engine idling and an engine cranking state. A method for providing stop-and-go functionality in a vehicle having a direct-start engine includes detecting a current engine state, rotating a motor shaft to energize a secondary HP fuel pump at a first threshold pressure during engine cranking, and rotating the shaft to energize an LP fluid pump at a second threshold pressure during engine idling and engine cranking. The secondary pumps can also be used when primary pumps are temporarily inoperable.

    摘要： A system for determining the position of a rotating wheel using RFID. In one embodiment, the system includes a position sensing wheel mounted to one or both of a crankshaft and a camshaft in the engine. A plurality of RFID tags are disposed at predetermined intervals around the wheel, and an RFID transceiver is positioned proximate the wheel. As the wheel rotates, the RFID transceiver transmits a signal that interrogates the RFID tags, which then transmit a coded signal to the transceiver identifying the wheel's position relative to the transceiver. Therefore, regardless of the position of the wheel, the RFID transceiver can interrogate the closest RFID tag and immediately know the position of the engine so that an engine controller can provide fuel and spark to the cylinders as soon as possible.
