Patent ID: 10280851

Abstract:
Disclosed are a method and device for determining a model of flowrate for a valve, including: instantiation of the model initially equal to an approximate model; choosing flowrate setting; determination of an initial command corresponding to the flowrate setting by the model; application of the initial command to the valve; observation of a discrepancy indicative of a difference between the flowrate setting and a flowrate achieved; if the discrepancy is not zero, application of a correction to the initial command, and return to the application step; if the discrepancy is zero, correction of the model by replacing, for the flowrate setting, the initial command by the corrected command, where the flowrate passing through the valve ends up in a combustion engine admission collector including a small-area controller regulating the flowrate of air admitted, and where the discrepancy of the observation step is the deviation of the small-area controller.
