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.
