Abstract

A method of influencing an automated transmission of a motor vehicle having a tractional resistance detection unit, the method comprising the steps of reading data, via the tractional resistance detection unit, containing at least information about a torque of a drivetrain, a rotational speed of the drive train, and an acceleration of the vehicle, determining the external tractional resistance of the vehicle based upon the read data, and influencing the shift program by at least one of activation, adaptation and variation of the shift program, on a basis one of an actual and a statistically prepared data about the external tractional resistance of the vehicle.
