摘要: An engine control system comprises a clutch cut off enable module and a torque control module. The clutch cut off enable module generates an enable signal based on a clutch engagement signal and an accelerator pedal signal. The torque control module reduces a spark advance of an engine to a minimum value and disables fueling of cylinders of the engine based on the enable signal. The minimum value is a minimum allowed spark advance for current engine airflow.

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 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.
