Claim 10:
11. The method of claim 10, further comprising:
using 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;
blending during the engine warmup, a cold-warm scaler blend containing the 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 blending 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
generating 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 in accordance with instructions provided by the processor.
