摘要: 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.

摘要: 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.

摘要: An engine control module comprises a base reserve module, a power steering reserve module, a reserve torque module, first and second engine actuator modules, and an engine speed control module. The base reserve module determines a base reserve torque. The power steering reserve module determines a power steering reserve torque. The reserve torque module determines a first reserve torque based on the base reserve torque, the power steering reserve torque, and at least one of an oil temperature of an engine and a barometric pressure. The first and second engine actuator modules control first and second actuators of the engine, respectively. The engine speed control module instructs the first engine actuator module to produce a first torque output from the engine and instructs the second engine actuator module to produce a second torque output from the engine.
