Abstract
The invention relates to a learning control method for adjusting the composition of an operating mixture for an internal combustion engine. The method includes the steps of: detecting the actual value of the composition; forming a control variable as a function of the instantaneous deviation of the actual value from the desired value; logically coupling the control variable to a base value of an adjusting parameter of the composition and driving an actuator on the basis of the logically coupled value; and, learning of an additional intervention in the control loop from the performance of the control loop wherein the learning takes place at a speed which is at least dependent upon temperature.
