Abstract: An engine control module comprises a torque control module, an engine speed (RPM) control module, and an actuator module. The torque control module determines a first desired torque based on a requested torque. The RPM control module selectively determines a second desired torque based on a desired RPM. The torque control module determines the first desired torque further based on the second desired torque when the engine control module is transitioning from an RPM control mode to a torque control mode. The RPM control module determines the second desired torque further based on the first desired torque when the engine control module is transitioning from the torque control mode to the RPM control mode. The actuator module controls an actuator of an engine based on the first and second desired torques.

Abstract: 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.

Abstract: An engine control system comprises a torque control module, an air conditioning (A/C) load comparison module, and an A/C load compensation module. The torque control module controls an engine to produce a first torque request based on a first torque maintains a current speed of the engine. The A/C load comparison module compares a transient load to a difference between a torque available to the engine and the first torque request. The A/C load compensation module selectively increases the first torque request prior to a clutch engagement based on the comparison.
