Abstract: A method of measuring exhaust gas temperatures in an exhaust pipe of an internal combustion engine is disclosed. A value of a mass flow rate of exhaust gasses flowing into the exhaust pipe is determined. A signal yielded by a temperature sensor located in a first point of the exhaust pipe is sampled and applied as input to a first computational module that yields a corresponding first output signal. A value of the temperature of the exhaust gasses flowing in the first point of the exhaust pipe is calculated on the basis of a value of the first output signal.
