Selective cylinder disablement control systems and methods

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.

1. An engine control system for an auto-stop/start vehicle, comprising:
a mode control module that selectively initiates an engine startup event when an engine startup command is generated; and an actuator control module that cranks an engine during the engine startup event, that provides fuel to a first cylinder of the engine while the engine is being cranked, that determines a predicted torque that the first cylinder will produce based on the fueling of the first cylinder, that, based on the predicted torque, determines a predicted engine speed for a combustion event of a second cylinder while the engine is being cranked, and that selectively disables fuel to the second cylinder while the engine is being cranked based on a comparison of the predicted engine speed and a target engine speed for the combustion event, wherein the second cylinder is after the first cylinder in a firing order.
