Abstract: An engine torque control module comprises a derivative module and a cylinder torque module. The derivative module determines a derivative term for a first cylinder of an internal combustion engine based on rotation of a crankshaft and determines an average derivative term for the first cylinder based upon the derivative term. The cylinder torque module determines an operating condition of the first cylinder based on the average derivative term, adjusts a torque output of the first cylinder based on the operating condition, and adjusts a torque output of a second cylinder based on the operating condition.

Abstract: A method of achieving a desired engine speed of an internal combustion engine includes determining the desired engine speed, calculating a slow response torque value based on the desired engine speed and calculating a fast response torque value based on the desired engine speed. A slow response actuator command and a fast response actuator command are generated based on the slow response torque value and the fast response torque value, respectively. Operation of the engine is regulated based on the slow response actuator command and the fast response actuator command to achieve the desired engine speed.

Abstract: Internal combustion engine control is generally in accordance with RPM and torque modes. Transition from RPM to torque control is accomplished by employing a mass airflow term accounting for any nonequivalence between RPM mode and torque mode mass airflows corresponding respectively to an RPM mode mass airflow and a closed-throttle mass airflow contribution to a total torque mode mass airflow.
