Abstract (en)
[origin: WO2014041272A1] The invention relates to a method for determining the pressure P avcm upstream of a mechanical compressor (3) forming part of a twin turbocharging circuit of a heat engine. The pressure is determined using a dynamic model based on a law of conservation of flow rates in the volume upstream of the mechanical compressor. The model links the pressure P avcm upstream of the mechanical compressor (3) at a temperature T avcm upstream of the mechanical compressor (3), to a supercharging pressure P sural and temperature T sural at the intake of the engine, as well as the bypass opening of the bypass valve (4).
