    摘要: A control system includes a temperature determination module and a catalyst protection module. The temperature determination module determines a temperature of exhaust gas based on a resistance of a heating element of an oxygen sensor. The catalyst protection module adjusts an operating parameter of an engine to decrease the temperature of the exhaust gas when the temperature of the exhaust gas is greater than a threshold temperature. The threshold temperature is based on a temperature that damages a catalyst in an exhaust system.

    摘要: A control system for a powertrain includes an energy determination module and a speed control module. The energy determination module determines a rotational energy input to the powertrain during a first period of a negative lash event of the powertrain. The speed control module selectively limits an increase in a rotational speed of the engine to a first predetermined rate based on the rotational energy during a second period of the negative lash event following the first period. The rotational energy is based on an acceleration rate of the rotational speed, and the speed control module limits the increase when the acceleration rate is greater than a predetermined acceleration rate. The speed control module further selectively increases the rotational speed at a second predetermined rate during a third period beginning at an end of the second period. A related method is also provided.

    摘要: An engine control system includes an inertia phase detection module, a feed-forward (FF) engine speed module, a FF APC module, a FF phaser postion module, and a phaser control module. The inertia phase detection module determines when an inertia phase of a gear shift is occurring within a transmission. The FF engine speed module predicts an engine speed for a future time when the inertia phase ends. The FF APC module predicts an air-per-cylinder (APC) for the future time based on the engine speed. The FF phaser position module determines a FF phaser position based on the engine speed and the APC. The phaser control module controls a camshaft phaser position based on the FF phaser position during the inertia phase of the gear shift.

    摘要: A control system for an engine includes a first spark control module and a second spark control module. The first spark control module retards spark timing for M of N cylinders of the engine to a first spark timing during a period before deactivating or after reactivating the M cylinders, wherein M is an integer greater than or equal to one, and wherein N is an integer greater than M. The second spark control module advances spark timing for (N−M) active cylinders of the engine to a second desired spark timing during the period before deactivating or after reactivating the M cylinders, wherein the second spark timing is greater than the first spark timing.
