Title: Method and device for controlling an internal combustion engine

Abstract: A method and a device for controlling an internal combustion engine. An actuator serves to influence the quantity of exhaust gas recirculated. A loop controller preselects the quantity of exhaust gas to be recirculated on the basis of a setpoint and an actual value which characterizes the quantity of exhaust gas recirculated. A first measured value is determined in a first position (open) of the actuator, and a second measured value is determined in a second position (closed) of the actuator, with the actual value or a correction value being preselectable on the basis of the difference between the two measured values.
