Abstract
The invention relates to a method () for monitoring a torque of an electric motor (), in particular for application in a motor vehicle, wherein the electric motor () is supplied with electric current (IS, IS, IS) in multiple phases. A first torque value (M) of the torque generated by the electric motor () is determined () on the basis of the electric output of the electric motor () and a detected rotational speed (n) of a rotor of the electric motor (). A second torque value (M) is determined on the basis of at least one measured phase current (IS, IS, IS) and a rotational position of the rotor, and the two determined torque values (M, M) are compared () to one another for plausibility checking.
