Abstract
In an arrangement for the cyclic adaptation of a characteristic for the changes in an automatic gearbox, a gear-change strategy which determines correction values by an algorithm that correlates external influencing variables and by a process involving evaluation of measured actual values of the influencing variables is used to adapt the characteristic both in the direction of the coordinate indicating a parameter dependent on the speed of travel and in the direction of the coordinate indicating a parameter associated with the engine torque. The process of adaptation is performed as a function of respectively associated correction values.
