Abstract
A method for controlling gear shifts in an automated stepped gear transmission of a motor vehicle in which operating parameters of the motor vehicle are continuously determined and evaluated for initiating and carrying out a shift from a currently engaged gear to a target gear such that, before a shift, the shift speed for initiating the shift and the target gear are determined. For better adaptation of the shift, in particular the determination of the shift speed and the target gear, to the current driving and operating conditions of the motor vehicle, the shift types 'shift-speed-orientated shift' and 'target-speed-orientated shift' are provided and, immediately before a shift operation, it is decided, as a function of at least one of the operating parameters in which, of the two shift types, the shift is to be carried out.
