International Classification:

F01L001/34

US Classification:

123 9015, 123 9017, 123399

Abstract:

A torque control system for regulating operation of a displacement on demand engine that is operable in an activated mode and a deactivated mode includes a throttle that regulates air flow into the engine and a cam phaser that regulates a torque output of the engine. A first module determines a throttle area based on a desired deactivated manifold absolute pressure (MAP) and a desired mass air flow (MAF) and a second module determines a desired cam phaser position based on an engine speed and a transitional air per cylinder (APC) that is determined based on one of a desired deactivated APC and desired activated APC. A third module generates a throttle control signal to control the throttle based on the throttle area and a fourth module generates a cam phaser control signal to control the cam phaser based on the desired cam phaser position.

International Classification:

F02D 13/00

US Classification:

123347, 123348, 123350

Abstract:

A torque control system for regulating operation of an engine includes a throttle that regulates air flow into the engine and a device that regulates a torque output of the engine. A first module determines a throttle area based on a desired manifold absolute pressure (MAP) and a desired manifold air flow (MAF) and a second module determines a device set-point based on a desired air per cylinder (APC) and an engine speed. A third module generates a throttle control signal to control the throttle based on the throttle area and generates a device control signal to control the device based on the device set-point.

Abstract:

A method of regulating a torque output of an internal combustion engine in a hybrid electric vehicle includes determining whether a cam phaser system of the engine is in one of an inactive state and an active state and monitoring at least one engine operating parameter. An engine torque array is selected from a plurality of engine torque arrays based on the one of the inactive state and the active state. An available engine torque is determined based on the engine torque array and the at least one engine operating parameter and the engine is regulated based on the available engine torque.

International Classification:

G06G 7/70

US Classification:

701102, 701103, 701110, 701115

Abstract:

A control system and method of regulating operation of an engine includes a minimum torque module that determines a torque request based upon at least two of measured revolutions per minute (RPM) of an engine, a barometric pressure, and a coolant temperature of the engine. A first engine air module can determine a first desired engine air value based upon predetermined actuator values and a torque value based upon the torque request. The predetermined actuator values can include a predetermined RPM of the engine. A throttle area module can determine a desired throttle area based upon the first desired engine air value and the predetermined RPM.
