The present invention relates to a monitoring device (KE) for operation of an electric machine in a vehicle (F), comprising a control unit (SE), which is or can be connected to a rotational-speed sensor (DG) of an electric machine (EM) of the vehicle (F) and to the electric machine (ME), wherein the control unit (SE) is or can be connected to a system controller (ST) of a vehicle component in the vehicle (F), and wherein the control unit (SE) is designed to determine a curve of the rotational speed of the electric machine by means of the rotational-speed sensor (DG) over a certain time period and to identify or rule out, from said curve, impending blocking of the electric machine for an impending operating time period and to operate the system controller (ST) in accordance with a predefined scenario for impending blocking in the impending operating time period and/or to operate the system controller (ST) in accordance with a predefined scenario for a lack of blocking in the impending operating time period.
