Systems and methods related to activating a parking lock system in the drive train of a vehicle having at least one electrical machine comprising a transmission which is connected to driven wheels. The method includes comparing a rotational speed nE of the at least one electrical machine with the transmission to a predetermined threshold value for a limiting speed nG, triggering, in the event that the rotational speed nE is below the threshold value for the limiting speed nG, a command for the actuation of an actuator system for activating the parking lock system, triggering, in the event that the rotational speed nE exceeds the threshold value for the limiting speed nG, a command for preventing an actuation of an actuator system for activating the parking lock system, and miming through a second comparison stage so long as nE≥nG.
