Abstract

The invention relates to a method for determining the pressure Pupstream of a mechanical compressor () equipped with a double supercharging circuit of a combustion engine. The pressure Pis determined by a dynamic model based on a law of conservation of flow rate in the volume upstream of the mechanical compressor. The model links the pressure Pupstream of the mechanical compressor () to a temperature Tupstream of the mechanical compressor (), to a boost pressure Pand boost temperature Ton the intake side of the engine, and to an openness Bypass of the bypass valve ().
