System and method for achieving an adjustable accelerator pedal reaction in a vehicle powertrain

System and method for controlling a drive unit in a vehicle drive train with a driver operated vehicle accelerator pedal whereby a Fahrzeugraddrehmoment can be instructed by the driver of the vehicle (10), the method comprising: moving the accelerator pedal (10) to an accelerator pedal position signal (14) to build; Selecting a design parameter for a transfer function (18); Monitoring the vehicle speed; Forming a pedal position signal (14) by means of a pedal position / pedal position signal transfer function which is designed by the selected design parameters (18); and forming a Fahrzeugraddrehmomentanforderung, based on a pre-calibrated functional relationship between the vehicle speed and the Fahrzeugraddrehmoment for a given pedal position signal.
