Abstract

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 nof the at least one electrical machine with the transmission to a predetermined threshold value for a limiting speed n, triggering, in the event that the rotational speed nis below the threshold value for the limiting speed n, a command for the actuation of an actuator system for activating the parking lock system, triggering, in the event that the rotational speed nexceeds the threshold value for the limiting speed n, 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 n≥n.
