A method and system for verifying operation of a motor propulsion plant fitted to an automotive vehicle with electric or hybrid traction, the motor propulsion plant including an electric motor including a permanent-magnet rotor. The method includes: a regulation of currents of a stator and a measurement of direct and quadratic components of the currents; an application, in a model of the electric motor linking control signals to the direct and quadratic components of the currents, of a change of variable in which X=Iq3+Id3, Y=Iq−Id; determination of minimum and maximum bounds for X and Y to deduce therefrom minimum and maximum bounds for Iq and Id; and a comparison between the measured direct and quadratic components of the currents and the minimum and maximum bounds for Iq and Id.
