Abstract
A method of controlling an internal combustion engine is provided, in which at least two operating states are differentiated, at least one operating variable of the engine being controlled, a setpoint torque being predetermined on the basis of the optimum operating point for the respective operating state and on the basis of the position of a throttle valve operated by the driver, and the value of at least one operating variable to be output being determined from the setpoint torque. A cylinder-individual firing angle retardation value is predetermined by a knock control system, so that the cylinder-individual firing angle retardation value is taken into account directly in calculating the setpoint torque.
