Abstract

The comfort level gear shift motor vehicle with an automated gear-shifting transmission is determined by shift parameters, which are dependent on driving parameters and on a shift program mode. The shift program mode identified through a characteristic parameter, which can vary a range of parameter values corresponding to a range of shift program modes. The method has the steps of detecting current values the driving parameters, detecting a current value of the characteristic parameter, determining respective minimum and maximum values that each of said shift parameters can assume within the range of characteristic parameter values as a function of the current driving parameter values, calculating actual shift parameter values as intermediate values between said maximum and minimum values for each of said shift parameters based on said current value of the characteristic parameter, and performing the gear shift with the actual shift parameter values.
