Patent ID: 7533658

Claim:
A mass air flowrate (MAF) control system comprising: a throttle that opens to a predetermined number of throttle openings including a maximum throttle opening; an exhaust gas recirculation (EGR) valve; a first module that determines a MAF command based on a MAF error; and a second module that opens said throttle to said maximum throttle opening and adjusts said EGR valve based on said MAF command when said MAF command is less than a maximum EGR opening and that, when said MAF command is greater than said maximum EGR opening: determines an intermediate throttle opening based on a difference between said MAF command and said maximum EGR opening; adjusts said throttle based on a nearest one of said predetermined number of throttle openings that is greater than said intermediate throttle opening; and adjusts said EGR valve based on a difference between said MAF command and said nearest one of said predetermined number of throttle openings that is greater than said intermediate throttle opening.
