The invention relates to a method for activating a parking lock system (20) in the drive train (18) of a vehicle (10) having at least one electrical machine (24) comprising a transmission which is connected to driven wheels (16), wherein the following method steps are carried out: a) comparing a rotational speed nE of the at least one electrical machine (24) with the transmission to a predetermined threshold value for a limiting speed nG, b) in the event that the rotational speed nE is below the threshold value for the limiting speed nG, triggering (38) a command for the actuation of an actuator system for activating the parking lock system (20) takes place, c) in the event that the rotational speed nE exceeds the threshold value for the limiting speed nG, the triggering of a command for actuation of an actuator system for activating the parking lock system (20) is prevented (42), and d) miming through a second comparison stage (44) so long as nE≥nG and, when nE≤nG is reached, branching to method step b).
