    摘要: A system includes a net mean effective pressure (NMEP) error module, a correction determination module, a mean effective pressure (MEP) correction module, and an actuator control module. The NMEP error module determines an NMEP error for a combustion cycle of a cylinder based on an expected NMEP for the combustion cycle, a measured NMEP for the combustion cycle, and a difference between an expected change in an engine speed for the combustion cycle and a measured change in the engine speed for the combustion cycle. The correction determination module determines an offset correction and a slope correction based on the NMEP error. The MEP correction module that generates a corrected NMEP for the combustion cycle based on the measured NMEP, the offset correction, and the slope correction. The actuator control module controls an engine operating parameter based on the corrected NMEP.

    摘要: A system for a vehicle, includes first, second, and third setpoint generation modules, a scaling module, and an actuator control module. The first setpoint generation module generates a first target value for an combustion parameter of an engine based on a predetermined value of a combustion stability of the engine. The second setpoint generation module generates a second target value for the combustion parameter based on a predetermined fuel efficiency. The scaling module generates a scaled value for the combustion parameter based on the first and second target values and a scalar value. The third setpoint generation module generates a third target value for the combustion parameter based on the first target value and the scaled value. The actuator control module controls at least one engine actuator associated with the combustion parameter based on the third target value.

    摘要: An engine control system comprises a ringing index (RI) determination module, a fueling threshold determination module, and a combustion mode determination module. The ringing index (RI) determination module determines an RI value of a cylinder of an engine and compares the RI value and a predetermined RI threshold. The fueling threshold determination module determines a fueling threshold and adjusts the fueling threshold based on the comparison of the RI value and the RI threshold. The combustion mode determination module selects a combustion mode for the engine based on a comparison of a current fueling rate and the fueling threshold.

    摘要: An engine control system for controlling transitions between activated and deactivated modes in a hybrid powertrain driven by a displacement on demand engine and an electric machine includes a calculator that calculates a desired powertrain torque. An engine control controls operation of the engine to produce an engine torque. An electric machine control controls operation of the electric machine to produce an electric machine torque. The electric machine torque supplements the engine torque to achieve the desired powertrain torque during a transition from the activated mode to the deactivated mode.
