ABSTRACT:
A method is specified for controlling a combustion engine in a motor vehicle, namely for optimally adjusting an air/fuel ratio which is distinguished in that the air/fuel ratio is the result of a regulation process. Individual aspects of the invention further address a regulation method particularly suitable for such regulation in consideration of the available input values and readings. For the purposes of supporting regulation, an adaptation method is specified which can also be used independently of the regulation method or with other regulation methods and which enables the regulation to be continuously adapted to the respective operating conditions, such as, for example, the engine operational performance, and signs of wear and tear and disruptions due to deposits etc. which accompany it.
