ABSTRACT:
In order to adapt the shifting characteristics of an electrohydraulically controlled, automatically shifting transmission continuously to the dirver's driving style or to a just existing or real time traffic situation, the driving speed (v), the lateral acceleration (aq), the longitudinal acceleration (alb), the longitudinal deceleration (alv) and the engine rotational speed (nmot) in addition to the throttle valve position alpha, are detected and by way of characteristic diagrams and a linking function are added to form a parameter from which, by filtering, a driving activity is determined. This driving activity is finally used for the selection of a shifting program from a plurality of shifting programs ranging from a consumption-optimized shifting program (SKF1) to a power-optimized shifting program (SKF5).
