Abstract
A control system for controlling power supply of an electric machine of an automobile and which contributes to movement thereof, wherein the control system is connected, at an input thereof, to a mechanism estimating a temperature of a rotor of the electric machine and to a temperature sensor measuring a temperature of a stator of the electric machine. The control system includes mappings of a set of values for allocating supply currents of the electric machine on the basis of torque and rotational speed request values received at the input of the control system, and includes a switching mechanism for selecting the mapping, the supply current signals of which are transmitted to the electric machine, on the basis of the signals from the mechanism estimating the temperature of the rotor and from the stator-temperature sensor.
