Disclosed is a method for managing a torque to be supplied on a shaft of an electric motor including the following steps: creating and initializing a correction data table; acquiring a torque instruction; determining a torque command; measuring the current output from the converter and measuring the current output from the battery; calculating an electrical power on the basis of the two current measurements and of the voltage; determining, on the basis of a map, a corresponding torque on the basis of the electrical power at the motor and of the rotational speed of the motor; reading the information provided by the motor relating to the torque exerted on its shaft; calculating the difference between the information provided by the motor and the torque determined on the basis of the electrical power; and updating the correction data table.
