Abstract:
A method is described for estimating the intake air flow rate in an internal combustion engine provided with an air intake system, wherein said system comprises valve means for controlling an intake air flow rate, characterized in that it comprises the phases of implementing a first and a second algorithm, suitable to determine respectively a first and a second engine intake air flow rate; and of selecting the first or the second flow rate, on the basis of a previously defined selection criterion.
