    摘要: 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.

    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.
