Abstract: The invention relates to a method for influencing an automated transmission taking into consideration the tractional resistance with which the magnitude of an external tractional resistance can be determined easily and without need of data exchange with devices outside the vehicle, the same as independently of a digitalized road map of the area in which the vehicle drives and with low construction complexity. In particular a topographical information of the area in which the vehicle drives is obtained which allows a tractional resistance detection unit, optionally in combination with additional influencing variables in relation to the external tractional resistance, to act upon the controller of an automated transmission so that by shifting the gear change points or selecting a suitable program, reduces both the fuel consumption and the pollutant and noise emissions.
