Abstract: Engine control apparatus includes, but is not limited to a determining device for determining whether or not the engine is operated under predetermined deceleration operating conditions or predetermined acceleration operating conditions and for individually deactivating two or more cylinders in a disenabling sequence which is different from the firing sequence if the engine is operated under predetermined deceleration operating conditions, and/or for individually reactivating two or more of the cylinders in a reactivating sequence which is different from the firing sequence if the engine is operated under predetermined acceleration conditions.

Abstract: An engine control system comprises a pedal torque determination module, a driver interpretation module, and an actuation module. The pedal torque determination module determines a zero pedal torque based on a desired engine torque at a zero accelerator pedal position and a minimum torque limit for an engine system. The driver interpretation module determines a driver pedal torque based on the zero pedal torque and an accelerator pedal position. The actuation module controls at least one of a throttle area, spark timing, and a fuel command based on the driver pedal torque.

Abstract: An engine control system comprises first and second integral modules, a summer module, and a torque adjustment module. The first integral module determines an engine speed (RPM) integral value based on a difference between a desired RPM and a measured RPM. The second integral module determines a torque integral value based on a difference between a desired torque output for an engine and an estimated torque of the engine. The summer module determines an RPM-torque integral value based on a difference between the RPM and torque integral values. The torque adjustment module determines a torque adjustment value based on the RPM-torque integral value and adjusts the desired torque output and the estimated torque based on the torque adjustment value.
