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. For each available combustion mode of the diesel engine, engine torque and speed ranges are received and a plurality of fuel losses and a plurality of emissions losses are retrieved, each fuel and emissions loss corresponding to respective ones of a plurality of engine operating points within the engine torque and speed ranges. The respective fuel and emissions losses are compared at each of a plurality of potential engine operating points within the engine torque and speed ranges of the available combustion modes. A desired engine operating point within one of the available combustion modes is selected that corresponds to one of the potential engine operating points having a lowest power loss based on the compared respective fuel and emissions losses.

Abstract: A throttle control system includes a target pressure module, a torque determination module, and a target opening module. The target pressure module determines an induction noise value based on an engine operating parameter and determines a target pressure downstream of a throttle valve of an engine based on a pressure at an inlet of the throttle valve and the induction noise value. The torque determination module determines a torque request for the engine based on the target pressure. The target opening module determines a target opening for the throttle valve based on the torque request and selectively adjusts opening of the throttle valve based on the target opening.

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 method of phasing the opening and closing of internal combustion engine intake and exhaust valves relative to the rotation of the crankshaft is based upon changes in engine speed, engine load and ambient relative humidity. During certain conditions of higher humidity, in order to maintain good combustion stability and thus overall engine operation, it is necessary to reduce intake and exhaust valve overlap by adjusting the phase of the intake and exhaust camshafts. This is achieved by utilizing a set of cam position reference values and constraints based upon engine speed, engine load and humidity that are contained in lookup tables that adjust and limit cam position and valve overlap. Generally speaking, in order to maintain optimum engine performance, intake and exhaust valve overlap is reduced with higher ambient humidity and vice versa.

Abstract: A method to determine reference actuator positions for a gasoline engine, includes entering a base torque request, a known spark advance, a known CAM position and a known exhaust gas recirculation (EGR) valve position into an inverse torque model to generate a first iteration desired air per cylinder (APC) value. The first iteration desired APC value is passed through a deadband filter to produce a filtered first iteration desired APC signal. A Predicted As Cal (PAC) spark advance is calculated for the filtered first iteration desired APC value. The PAC spark advance and the base torque request are modified, and data from a first lookup table is entered to generate a second iteration desired APC value.

Abstract: A method of controlling intake and exhaust cam phase in an internal combustion engine for optimal HVAC performance in a motor vehicle includes requesting a cabin heating value, sensing an engine speed and an engine load of the internal combustion engine, utilizing the cabin heating value, the engine speed and the engine load in one or more lookup tables to determine intake phaser constraint values and exhaust phaser constraint values for cabin heating, and transitioning the intake phaser constraint values and the exhaust phaser constraint values for cabin heating to intake phaser constraint values and exhaust phaser constraint values based on one or more lookup tables for normal operation without a cabin heating 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 air and exhaust setpoints for the spark ignition engine based on the second torque request. A model predictive control (MPC) module identifies sets of possible target values based on the air and exhaust 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. A throttle actuator module controls opening of a throttle valve based on a first one of the target values.
