摘要: A method for controlling processes in a motor vehicle is intended, for example, for open-loop/closed-loop control of combustion processes, transmission switching processes or braking processes. An engine characteristics map is formed by operating quantities of the respective process and is represented by a number of support points. In the corresponding control unit, for each support point a piece of information about the value of the map at the position of the support point is provided. In the open-loop/closed-loop control of the process, for a determined working point of the process at least one map value that is decisive for this working point is determined from the map and taking account of this, at least one control quantity for the emission of a control signal is formed. The map is automatically adapted to a changed process behavior. For the adaptation, a correction value is determined for a certain operating phase of the map. According to the present invention, additionally for each support point a piece of information about the position of the support point within the map is provided so that the support points are enterable independent of a fixed grid into the map. For adaptation of the map, a number of support points of the map lying around the determined correction value is chosen. These support points are then adapted, the support point correction being carried out distance-weighted with reference to the position of the determined correction value within the map.
