Abstract:
1. A control system for an internal combustion engine having exhaust gas recirculation means for recirculating a part of exhaust gases to an intake system of said engine, the control system comprising: estimated exhaust recirculation amount calculating means for calculating an estimated exhaust gas recirculation amount, using a neural network to which at least one engine operating parameter indicative of an operating condition of said engine is input, wherein said neural network outputs an estimated value of an amount of exhaust gases recirculated by said exhaust gas recirculation means; engine control parameter calculating means for calculating at least one engine control parameter for controlling said engine, based on the estimated exhaust gas recirculation amount, and exhaust gas recirculation amount detecting means for detecting the exhaust gas recirculation amount, wherein said engine control parameter calculating means has difference parameter calculating means for calculating a difference parameter indicative of a difference between the detected exhaust gas recirculation amount and the estimated exhaust gas recirculation amount, wherein said engine control parameter calculating means calculates the at least one engine control parameter according to the difference parameter.
