Claim:
1. An electric machine associated with an electronic control unit comprising: a group of embedded maps with a same setpoint parameter according to a first operating parameter and a second operating parameter of the electric machine, each of the maps being recorded in a same variation domain of the first and second operating parameters, each of the maps being associated with a different level of a third operating parameter of the electric machine, the maps including ranges of values having at least two different types of status, or permitted value ranges, and at least one range of extrapolated values, for at least one of the maps, wherein the electronic control unit is configured, when a value of a third operating parameter is associated with one of the embedded maps, for using as a setpoint value values belonging to the permitted value ranges excluding values belonging to the at least one range of extrapolated values, wherein the electronic control unit is configured, for values of the third operating parameter not associated with one of the embedded maps, for using interpolated values between two permitted values, or between a permitted value and an extrapolated value, wherein the same setpoint parameter is a current intensity value, and the same variation domain is represented between two torque values and between two values of rotation speed of the electric machine.
