    Abstract: A control system includes a control module that receives a first request corresponding to a control value for at least one of a plurality of actuators, selectively receives a second request associated with a predicted future control value for at least one of the plurality of actuators, determines a target value for the actuator based on the first request if the second request was not received, and generates a reference signal representing the second request if the second request was received. The reference signal indicates at least one of a predicted increase in the control value and a predicted decrease in the control value. A model predictive control module receives the reference signal and adjusts one of the plurality of actuators associated with the predicted future control value based on the reference signal.

    Abstract: A method for operating a multi-mode powertrain system includes monitoring an operator request for tractive power, and arbitrating the operator request for tractive power with axle torque constraints and crankshaft torque constraints. An immediate tractive torque request and a predicted tractive torque request are determined based upon the arbitrated operator request for tractive power. The predicted tractive torque request is shaped based upon driveability torque constraints. Operation of torque-generative devices of the multi-mode powertrain system are controlled based upon the predicted tractive torque request and the driveability-shaped predicted tractive torque request.

    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 generates setpoints for the spark ignition engine based on the second torque request. A vacuum requesting module requests an amount of vacuum within an intake manifold of the engine. The setpoint module selectively adjusts at least one of the setpoints based on the amount of vacuum requested. A model predictive control (MPC) module: identifies sets of possible target values based on the 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 powertrain system includes an internal combustion engine rotatably coupled to a non-combustion torque machine and a torque converter which is rotatably coupled to an input member of a transmission. A method for operating the powertrain system includes operating the torque converter in a controlled slip operating state and controlling a torque converter clutch capacity in response to a driver requested braking torque. Target torque outputs from the engine and from the torque machine are determined in response to the driver requested braking torque subjected to a time delay. A torque modifier for the torque machine is determined in response to a torque converter clutch slip error. Torque output from the engine is controlled in response to the target torque output from the engine, and torque output from the torque machine is controlled in response to the target torque output and the torque modifier from the torque machine.
