摘要：The invention relates to a method for determining the exhaust pressure (Pr) ofa turbocharged internal combustion engine, comprising a solenoid by-pass valve for theexhaust gas, characterised in that an exhaust pressure (Pi) is determined as a function ofthe inlet air flow to the engine, (Ar), the engine speed (Rr) and the degree of opening ofthe solenoid exhaust by-pass valve (Tr), by interpolation from a reference map
comprising exhaust gas pressure values (Pc) for given inlet air flow values (Ac), the enginespeed (Rc) and the degree of opening of the solenoid exhaust by-pass valve (Tc), and theexhaust pressure determined by the interpolation (Pi) is corrected as a function ofambient pressure values (Pa, Po).
