摘要： A hybrid powertrain includes an internal combustion engine, an electro-mechanical transmission and an electric machine. In an engine starting routine, flow control devices located proximate each combustion chamber in the engine initially restrict airflow into the cylinders to allow for a starter motor to rotate the engine at lower expansion and compression torque whereafter rotation of the engine is transitioned to the electric machine.

摘要： A system according to the principles of the present disclosure includes a stop-start module and a throttle control module. The stop-start module stops an engine when a driver depresses a brake pedal while an ignition system is on and the engine is idling. The throttle control module selectively opens a throttle valve when fuel injection in the engine is stopped while the ignition system is on based on engine speed and a manifold pressure within an intake manifold. The stop-start module starts the engine when the driver releases the brake pedal.

摘要： An engine system includes a stop-start module that generates a shut down signal to shut down an engine. A friction module that generates a friction signal based on the engine shut down signal. The friction signal indicates an estimate of a sum of friction forces between components of the engine. A position module estimates a position of the engine and generates a position signal. An energy module estimates kinetic energy of the engine based on the friction signal and the position signal. A cylinder deactivation module stops the engine based on the kinetic energy in at least one of (i) a predetermined position and (ii) a predetermined range.

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： 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 control system for an auto-stop/start vehicle includes a mode control module and an actuator control module. The mode control module selectively initiates an engine startup event when an engine startup command is generated. The actuator control module cranks an engine during the engine startup event, provides fuel to a first cylinder of the engine while the engine is being cranked, and selectively disables fuel to a second cylinder of the engine while the engine is being cranked. The second cylinder is after the first cylinder in a firing order.

摘要： An engine system of a vehicle includes an engine torque module. The engine torque module determines an engine output torque profile including predicted torque outputs based on an accelerator signal and an engine state variable. A load control module determines a dynamic transmission load profile based on the engine output torque profile and an engine speed profile. The dynamic transmission load profile includes transmission loads as a function of engine speed during an auto-start of an engine. A compensation module generates a torque compensation signal based on the dynamic transmission load profile. An actuator module compensates for a change in a transmission load based on the torque compensation signal and during a transition of the engine from a cranking state to an idle state.
