SYSTEM AND METHOD FOR MONITORING THE OPERATION OF AN INTERNAL COMBUSTION ENGINE WITH COMPENSATION FOR ERRORS IN THE INTAKE AIRFLOW MEASUREMENT

摘要

System for monitoring the operation of a motor vehicle internal combustion engine, comprising a member for measuring the flow of air admitted, characterized in that it comprises a means (21) for determining the standard deviation of the spread on the measured airflow as a function of the measured value, a means (24) for comparing the standard deviation thus determined against a calibration value in order to determine an estimated optimum flow rate for gases entering the engine, and a correcting means (25) for deducing a correction function to be applied to the measured airflow on the basis of the estimated optimum flow of gases entering the engine when learning conditions are satisfied.
