Claim 19:
20. The system of claim 19, further comprising:
wherein the processor is further configured to:
use a set of cam phaser values from a first, a second, and a third set of cam phaser calibration tables comprising a first calibration table containing cold cam phaser values, a second calibration table containing warm cam phaser values, and a third calibration table containing EGR cam phaser values;
blend during the engine warmup, a cold-warm scaler blend containing values between zero to one wherein the values of the cold-warm scaler blend provide the basis to apply the interpolate function between the cold cam phaser values and the warm cam phaser table values;
further blend as EGR is introduced comprising calculating the value for an EGR blend factor by dividing a final percentage EGR reference by a nominal percentage value of the EGR reference that corresponds to the current humidity wherein the EGR blend factor provides a basis to apply the interpolate function between the warm cam phaser values and the EGR cam phaser values; and
generate the set of values as reference target values that correspond to cam phaser commands for providing the amount of propulsion torque by the engine of the vehicle.
