    Abstract: A control method for selecting an optimal multiple step operating mode for a multiple cylinder motor vehicle engine system having variable lift includes prioritizing each of a full torque capacity (FTC) mode having all cylinders operating at high lift, a first reduced capacity economy mode (RCE1) having all cylinders operating at low lift, and a second reduced capacity economy mode (RCE2) having fewer than all of the cylinders operating at low lift with at least one cylinder deactivated based on predicted fuel economy of each of the modes. Multiple constraints are applied to each of the prioritized modes including incorporating boost as one of the constraints by calculating a maximum torque capacity for each mode that is a function of a current boost pressure. A mode determination arbitration is conducted to identify if a change in mode is required.

    Abstract: A torque requesting module generates a torque request for an engine based on driver input. A model predictive control (MPC) module: identifies sets of possible target values based on the torque request, each of the sets of possible target values including target pressure ratios across a throttle valve; determines predicted operating parameters for the sets of possible target values, respectively; determines cost values for the sets of possible target values, respectively; selects one of the sets of possible target values based on the cost values; and sets target values based on the possible target values of the selected one of the sets, respectively, the target values including a target pressure ratio across the throttle valve. A target area module determines a target opening area of the throttle valve based on the target pressure ratio. A throttle actuator module controls the throttle valve based on the target opening.

    Abstract: A controller architecture for a vehicle including a multi-mode powertrain system includes an engine controller having a control routine for determining and executing engine torque commands responsive to a hybrid engine torque command, and a control routine for determining a propulsion axle torque command responsive to an output torque request. The controller architecture further includes transmission controller having a control routine for selecting and effecting operation of the passive transmission in a preferred gear responsive to the output torque request. The controller architecture further includes a hybrid controller having control routines for determining and executing torque commands for each of the non-combustion torque machines and for determining the hybrid engine torque command to achieve a desired axle torque in response to the propulsion axle torque command with the passive transmission operating in the preferred gear.

    Abstract: A method of warming a catalyst of an exhaust gas treatment system of a hybrid vehicle includes transitioning a rotational speed of an engine to within a pre-defined speed range with an electric motor, and reducing an engine manifold pressure to within a pre-defined pressure range. The engine is fueled after the rotational speed of the engine is within the pre-defined speed range, and the engine manifold pressure is within the pre-defined pressure range. While the engine is being fueled, the engine manifold pressure is increased to within a catalyst light-off pressure range, and the torque output of the engine is increased to within a catalyst light-off operating torque range. The exhaust gas produced from the operation of the engine within the pre-defined speed range, within the catalyst light-off pressure range, and within the catalyst light-off operating torque range heats the catalyst while minimizing emissions.
