Abstract

A method and a device are described for controlling an internal combustion engine. On the basis of the comparison of a setpoint value with an actual value for a variable that characterizes the supplied oxygen quantity, an actuating variable is predefined for controlling an actuating element that influences the fuel quantity conducted to the internal combustion engine and/or the oxygen quantity supplied to the internal combustion engine. The actual value and/or the setpoint value are/is normalized to a reference value.
