Abstract
A method for estimating the temperature of exhaust gases of a combustion engine at an output of an EGR circuit fitted on the engine, based on a model that takes into account thermal energy losses of the exhaust gases at an EGR cooler or EGR circuit, the model also taking into account thermal exchange between the exhaust gases and the walls of a duct conveying the exhaust gases to the EGR cooler. A vehicle can implement such an estimation.
