Abstract
A method for controlling the gear release in an automated multi-speed drive in a vehicle drive with a drive motor and a separating clutch positioned between the drive motor and the multi-speed drive that the events 'application of a shifting power' and 'opening of the separating clutch' are determined dependent on reaching certain vehicle accelerations (a, a). The vehicle acceleration (a) decreases at the beginning of the shifting process due to the reduction of the fuel injection quantity (EM) supplied to the drive motor.
