The invention relates to a method for monitoring the operation of an electric machine of a vehicle used as drive, during braking of the vehicle, by means of speed-controlled operation of the electric machine, to a standstill and/or during stopping of the vehicle by means of speed-controlled operation of the electric machine to a standstill, wherein a speed differential (nDiff) between an actual speed (nist) and a target speed (nsoll) of the electric machine is determined, wherein, on the basis of the speed differential (nDiff) and a corresponding threshold value, it is checked whether one or more criteria (K1, K2, K3, K3', K4) are met, and wherein, if the one criterion or at least one of the plurality of criteria (K1, K2) is met, a fault (F) of the operation of the electric machine is identified.
