摘要
System for controlling an EGR valve of an internal combustion engine based on a flow model (1), the flow model (1) estimating an EGR flow rate (dmEGR_Est) outgoing from the EGR valve to control an opening/closing of said EGR valve, on the basis of operating parameters (p2, p3, T_EGR) of the internal combustion engine; the method being characterized in that it models said EGR valve as a nozzle and it calculates a relative equivalent outflow area (Aeff) to correct said estimation of the EGR flow rate dmEGR_Est.
