    摘要: A system for a vehicle, includes a rockback detection module and a starter disabling module. The rockback detection module receives a crankshaft position signal from a bi-directional crankshaft sensor and selectively indicates that a crankshaft of an engine is rotating in a first direction based on the crankshaft position signal. The engine rotates in a second direction that is opposite to the first direction when the engine is running. The starter disabling module disables current to a starter motor when the crankshaft is rotating in the first direction.

    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.

    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.
