ABSTRACT:
An automatic transmission control method in which at least one of a starting clutch, a clutch coupling and transmission elements, for selection as well as engagement and disengagement of a gear step, are determined as a function of respectively existing variables representing the driving situation as well as the driver's wishes can be activated by actuators which are controlled by a control and regulation device. The method comprising the steps of collecting and normalizing the input variable into standard input variables; weighting with weighting factors and summarizing; converting the weighted input variables into intermediate variables; selecting a specific range of values which represents a specific shifting sequence; and implementing the shifting operation.
