The present invention relates to a method for monitoring the driving torque of an electric traction machine of an electrified vehicle, involving determining (22) a torque difference (EC) between a setpoint torque (CC) and an achieved torque (CR), and determining (23) whether the rotor is rotating in the forward driving direction or the reverse driving direction. According to the invention, the method involves comparing (24) the torque difference (EC) against a first threshold (S1) in the forward driving direction, and comparing (27) the torque difference (EC) against a second threshold (S2) in the reverse driving direction, and activating a reconfiguring (25, 28) of the electric machine on the basis of the result of the comparison (24, 27), the second threshold (S2) having a higher value than the first threshold (S1). The invention applies to electrified vehicles with fully electric drive and with hybrid drive.
