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, an automatic transmission having a threshold fluid pressure sufficient for enabling operation of the transmission when the engine is off, a controller, and a fuel delivery system. The controller determines the presence of predetermined engine states, and optimizes a stop-and-go functionality of the engine. The fuel delivery system includes a motor and an integrated pump assembly having a secondary high-pressure (HP) fuel pump which is selectively connectable to a rotatable shaft of the motor, and a secondary low-pressure (LP) fluid pump which is continuously connected to the shaft. The motor continuously energizes the secondary LP fluid pump via the rotatable shaft to thereby maintain the threshold fluid pressure during a first or second engine state, and selectively energizes the secondary HP fuel pump via the rotatable shaft to maintain the threshold fuel pressure during the second engine state.

摘要： An engine system includes a first module that determines a cylinder of an engine to be in one of M prediction types and generates a distance from intake signal indicating a number of prediction steps the cylinder is away from an intake stroke. M is an integer greater than or equal to 3. A second module determines a cycle type of the cylinder. The cycle type indicates a number of combustion cycles the cylinder has experienced from a last restart of the engine. A cylinder air charge module estimates an air mass within the cylinder based on the distance from intake signal and the cycle type.
