Abstract (en)

[origin: WO2008059153A2] The invention relates to a method for estimating the temperature T<SUB>3</SUB> of the exhaust gases of a combustion engine at the output of a EGR circuit fitted on the engine, based on a model that takes into account the thermal energy losses of the exhaust gases at the EGR cooler or EGR circuit, characterised in that the model also takes into account the thermal exchange between the exhaust gases and the walls of a duct conveying said exhaust gases to the EGR cooler. The invention further relates to a vehicle capable of implementing such estimation.
