The phaser control module determines target intake and exhaust phasing values based on the second torque request and selectively adjusts intake and exhaust valve phasers based on the target intake and exhaust phasing values, respectively. The EGR control module determines a target EGR opening based on the first torque request and selectively adjusts an EGR valve based on the target EGR opening.

Abstract: A fuel control module transitions engine fueling from rich to lean. A catalyst fault detection module diagnoses whether a fault is present in an exhaust catalyst based on a response of an oxygen sensor to the transition. A prediction module generates a prediction based on a model and a set of possible target values. A cost module determines a cost for the set of possible target values based on comparisons of the prediction with minimum and maximums. Before the transition, a constraint module selectively adjusts at least one of the minimum and maximums for the fault diagnosis. Based on the cost, a selection module selects the set of possible target values from a group of sets of possible target values and sets target values based on the selected set of possible target values. An actuator module controls an engine actuator based on a first one of the target values.

Abstract: A torque requesting module generates a first torque request for a spark ignition engine based on driver input. A torque conversion module converts the first torque request into a second torque request. A setpoint control module, based on the second torque request, generates a mass of air per cylinder (APC) setpoint, an exhaust gas recirculation (EGR) setpoint, an intake valve phasing setpoint, and an exhaust valve phasing setpoint. A model predictive control (MPC) module: identifies sets of possible target values based on the APC, EGR, intake valve phasing, and exhaust valve phasing setpoints; generates predicted parameters based on a model of the spark ignition engine and the sets of possible target values, respectively; selects one of the sets of possible target values based on the predicted parameters; and sets target values based on the possible target values of the selected one of the sets.

Abstract: A method for selecting an engine operating point in a multi-mode powertrain system includes monitoring a desired axle torque based on an operator torque request and vehicle speed. When an aftertreatment device used to purify regulated constituents within an exhaust gas feedstream output from the engine is determined to require an exhaust gas feedstream temperature to be increased to a predetermined temperature, an intrusive engine operation mode is enabled to increase the exhaust gas feedstream temperature to the predetermined temperature. A plurality of engine power is retrieved, wherein each engine power loss corresponds to respective ones of a plurality of intrusive engine operation points each achieving the predetermined temperature of the exhaust gas feedstream. A desired engine operation point is selected corresponding to one of the intrusive engine operation points having a lowest total power loss.
