Abstract
A method for operating an internal combustion engine is described. A base controlled variable for influencing an actual value of an operating variable of the internal combustion engine is ascertained. The actual value of the operating variable is compared to a setpoint value of the operating variable. A correcting variable is ascertained as a function of the comparison. A controlled variable is ascertained as a function of the base controlled variable and as a function of the correcting variable. An actual value of a state variable of the internal combustion engine is ascertained. A start point in time of a time interval of a critical state change of the internal combustion engine is ascertained as a function of the ascertained actual value of the state variable. The controlled variable is essentially ascertained from an intermediate controlled variable and a correcting variable following the start point in time.
