Abstract

The invention relates to a method for estimating the exhaust gas pressure (P31) upstream from the turbine of a supercharger in a vehicle internal combustion engine. The method comprises estimating the turbine upstream pressure (P31) using the following relation Formula P31-P41 = f1*f2(P21-P1)+f3 in which P41 is the exhaust gas pressure downstream from the turbine, P1 is the air intake pressure upstream from the supercharger, P21 is the air pressure downstream from the supercharger, and the functions f1; f2, and f3 are corrective functions that depend on numerous parameters.
