1. A method of changing a comfort level of a gear shift in a motor vehicle with an automated gear-shifting transmission, an engine and a clutch, wherein said comfort level is characterized by shift parameters which are dependent on driving parameters characterizing a driving situation of the vehicle and are further dependent on a shift program mode that is identified through a characteristic parameter, said shift program mode being one of a driver-selected and an automatically determined shift program mode, wherein a range of characteristic parameter values correlates to a range of shift program modes;

  • the method comprising;

    detecting current values of the driving parameters;

    detecting a current value of the characteristic parameter;

    determining respective minimum and maximum values that can be assumed by each of said shift parameters as a function of the current driving parameter values dependent on the characteristic parameter value;

    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.
