    摘要: A method of achieving a desired torque output of an internal combustion engine includes determining a first air-per-cylinder (APC) value based on a first APC relationship and determining a second APC value based on a second APC relationship. An APC error is determined based on the second APC value. Operation of the engine is regulated based on the first APC value when the APC error is greater than a threshold error. Operation of the engine based on the second APC value when the APC error is not greater than the threshold error.

    摘要: 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.

    摘要: An engine control system comprises a torque request module, an immediate torque control module, an actuation module, and an expected torque control module. The torque request module generates an expected torque request and an immediate torque request. The immediate torque control module controls a spark advance of an engine based on the immediate torque request. The actuation module selectively reduces the expected torque request based on the immediate torque request and a spark capacity. The spark capacity is based on a difference between a first engine torque and a second engine torque, determined at a current airflow. The first engine torque is determined at a first spark advance and the second engine torque is determined at a second spark advance that is less than the first spark advance. The expected torque control module that controls a throttle valve area based on the expected torque request.

    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.
