Abstract
The invention relates to a method for determining the pressure Pavcm upstream of a mechanical compressor (3) equipped with a double supercharging circuit of a combustion engine. The pressure Pavcm is 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 Pavcm upstream of the mechanical compressor (3) to a temperature Tavcm upstream of the mechanical compressor (3), to a boost pressure Psural and boost temperature Tsural on the intake side of the engine, and to an openness Bypass of the bypass valve (4).
