Title: Method for regulating the speed of a drive motor

Abstract: The invention involves a process for controlling the rotational speed of a drive motor during a start-up period, in a drive train, containing at least one starter element that can be coupled to the drive motor, in a rotationally fixed manner, in the form of a hydrodynamic coupling, containing a primary blade wheel and a secondary blade wheel, which form together at least one toroid-shaped working space. According to the invention, the rotational speed of the drive motor is set as a function of the power that can be consumed by the hydrodynamic coupling. The consumable power can be controlled or regulated.
