    摘要： An engine control system comprises a base air per cylinder (APC) module, a catalyst temperature adjustment module, an ambient temperature adjustment module, and an APC adjustment module. The base APC module determines a base APC to reduce first engine pumping losses during a first deceleration fuel cutoff (DFCO) event relative to second engine pumping losses during a second DFCO event. The catalyst temperature adjustment module determines a catalyst temperature adjustment based on a catalyst temperature during the first DFCO event. The ambient temperature adjustment module determines an ambient temperature adjustment based on an ambient air temperature during the first DFCO event. The APC adjustment module selectively adjusts the base APC based on the catalyst temperature adjustment and the ambient temperature adjustment and controls at least one of the engine airflow actuators based on the adjusted base APC during the first DFCO event.

    摘要： A minimum torque module selectively determines a first minimum propulsion torque based on second and third minimum propulsion torques when a torque converter clutch is in unlocked and locked states, respectively. A zero pedal torque module selectively sets a zero pedal torque equal to the first minimum propulsion torque. A pedal request module determines a pedal torque request based on an accelerator pedal position, a vehicle speed, and the zero pedal torque. A driver request module determines a driver axle torque request based on the pedal torque request. A shaping module selectively shapes the driver axle torque request into a shaped driver axle torque request. A conversion module converts the first minimum propulsion torque into a minimum axle torque. A final driver request module sets a final driver axle torque request equal to a greater of the shaped driver axle torque request and the minimum axle torque.

    摘要： A hybrid engine control system comprises a hybrid engine control module and a torque mitigation module. The hybrid engine control module selectively stops an internal combustion engine (ICE). The hybrid engine control module selectively starts the ICE based upon driver inputs and non-driver inputs. The torque mitigation module reduces torque transfer from the ICE to a driveline while the ICE is started based upon the non-driver inputs and maintains torque transfer from the ICE to the driveline while the ICE is started based upon the driver inputs. A method comprises selectively stopping an internal combustion engine (ICE); selectively starting the ICE based upon driver inputs and non-driver inputs; reducing torque transfer from the ICE to a driveline while the ICE is started based upon the non-driver inputs; and maintaining torque transfer from the ICE to the driveline while the ICE is started based upon the driver inputs.

    摘要： A method for controlling a low-voltage circuit of a vehicle having a generator includes monitoring operating conditions of the vehicle and determining whether surplus generator load is available. Available surplus generator load is captured and used to power the low-voltage circuit. The low-voltage circuit may include a low-voltage battery, which may be charged with the surplus generator load. The surplus generator load may be utilized for anti-sulfation of the low-voltage battery. The method is usable with both a hybrid vehicle and a conventional vehicle. The method may further include powering the low-voltage circuit with energy stored in the low-voltage battery as a result of charging the low-voltage battery with the surplus generator load.
