摘要： A lubrication torque limit module includes a temperature module that determines a temperature of an engine and generates an engine temperature signal. A limit module generates a torque limit signal based on the temperature signal and a speed of the engine. The torque limit signal identifies an indicated torque maximum limit. A torque arbitration module limits indicated torque of the engine based on the indicated torque maximum limit. The indicated torque of the engine is equal to an unmanaged brake torque of the engine plus an overall friction torque of the engine.

摘要： An engine control system includes a disturbance module, a torque correction module, a torque-to-spark module, and a spark correction module. The disturbance module determines a disturbance value for a past combustion stroke of a cylinder of an engine based on rotation of a crankshaft. The torque correction module selectively determines a torque correction for a future combustion stroke of the cylinder based on the disturbance value. The torque-to-spark module determines a spark correction based on the torque correction and determines an uncorrected spark timing based on a torque request. The spark correction module determines a corrected spark timing based on the uncorrected spark timing and the spark correction and generates spark during the future combustion stroke based on the corrected spark timing.

摘要： An engine control system comprises a base air per cylinder (APC) module, a catalyst temperature adjustment module, an ambient temperature adjustment module, and an APC adjustment module. The base APC module determines a base APC to reduce first engine pumping losses during a first deceleration fuel cutoff (DFCO) event relative to second engine pumping losses during a second DFCO event. The catalyst temperature adjustment module determines a catalyst temperature adjustment based on a catalyst temperature during the first DFCO event. The ambient temperature adjustment module determines an ambient temperature adjustment based on an ambient air temperature during the first DFCO event. The APC adjustment module selectively adjusts the base APC based on the catalyst temperature adjustment and the ambient temperature adjustment and controls at least one of the engine airflow actuators based on the adjusted base APC during the first DFCO event.

摘要： An engine control system includes an air control module, a spark control module, a torque control module, a transient detection module, and a launch torque module. The air control module controls a throttle valve of an engine based on a commanded predicted torque. The spark control module controls spark advance of the engine based on a commanded immediate torque. The torque control module increases the commanded predicted torque when a catalyst light-off (CLO) mode is active, and increases the commanded immediate torque when a driver actuates an accelerator input. The transient detection module generates a lean transient signal when an air per cylinder increase is detected while the CLO mode is active. The launch torque module generates a torque offset signal based on the lean transient signal. The torque control module increases the commanded immediate torque based on the torque offset signal.

摘要： A method for selectively creating vacuum in a hybrid powertrain controlled by a hybrid control processor and having an engine controlled by an engine control module includes requesting a pressure differential between a first intake point and a second intake point, wherein the first intake point and the second intake point are separated by a throttle. An actual torque capacity is calculated for the engine, wherein the actual torque capacity occurs when pressure is substantially equal at the first intake point and at the second intake point. A desired torque capacity is also calculated for the engine, wherein the desired torque capacity reduces the pressure at the second intake point relative to the pressure at the first intake point, such that the requested pressure differential is created. The engine is then operated at one of the desired torque capacity and the actual torque capacity.
