Abstract

A process for determining an operating parameter of an internal combustion engine as a function of three control parameters (N, P, &lgr;) of this motor, comprises:a) establishing a first map of the operating parameter as a function of two control parameters, the third control parameter being fixed at a first value;b) establishing a second map of the operating parameter as a function of the two same control parameters, the third control parameter being fixed at a second value;c) establishing a relationship between the operating parameter and the third control parameter over all the range of variation of this parameter at at least one specific operating point; andd) using this relationship to determine the operating parameter as a function of the three control parameters at all points of operation of the motor.
