System for monitoring the torque supplied by the motor of a motor vehicle, notably of an electric or hybrid vehicle. The system comprises a means of determining the driver's request for torque, a means of estimating the torque produced by the propulsion unit, a means (1) of filtering the driver torque request which means is connected at input to a means (2) of determining the consistency between the torque request and the torque produced comprising a means (3) of determining the consistency of the positive torque and a means (4) of determining the consistency of the negative torque each one comprising a means (5, 7) of determining the phases of quasi-static variation of the request and a means (6, 8) of detecting torque anomalies which are able to construct an acceptable torque template and to determine that a torque anomaly has occurred as a function of the torque estimate, the torque request and the acceptable torque template.
