Abstract

A method and a device for controlling an internal combustion engine. A temperature variable and a pressure variable are detected by sensors. On the basis of at least the temperature variable and the pressure variable, a first quantity is determined that characterizes the air quantity, which is supplied to the internal combustion engine. A further sensor detects a second quantity that characterizes the air quantity, which is supplied to the internal combustion engine. The second quantity is adapted by the first quantity. Furthermore, the first quantity is used as a substitute value for the second quantity.
