Zusammenfassung:	A method for determining a value of an exhaust gas temperature in a predetermined position along an exhaust pipe of an internal combustion engine is provided. The method includes measuring a value of an exhaust gas temperature in the exhaust pipe with a temperature sensor and measuring a value of a pressure within a cylinder of the internal combustion engine with a pressure sensor. A value of an exhaust gas temperature in the exhaust pipe is estimated based on the measured pressure value. Whether the internal combustion engine is operating under a transient condition or not is detected. The value of the exhaust gas temperature in the predetermined position is determined based on the measured exhaust gas temperature value, if the transient condition is not detected. Otherwise, the value of the exhaust gas temperature in the predetermined position is determined based on the estimated exhaust gas temperature value.
