description A method for controlling an exhaust gas recirculation device in an internal combustion engine includes calculating an actual value of an exhaust gas recirculation rate from a current air flow rate measured by an air flow rate meter and a theoretical air flow rate that would result without exhaust gas recirculation. A difference is formed from a desired value stored as a function of load and from the actual value for the exhaust gas recirculation rate. The difference is supplied to a controller which triggers an exhaust gas recirculation valve in such a way that a desired value of the exhaust gas recirculation rate is established.
