Abstract
A method controlling a powertrain fitted in an automobile and including an electric motor including a rotor and stator, the method including: regulation of currents of the rotor and the stator via control signals from the electric motor, wherein the currents and control signals are expressed in a rotating coordinate system and include a plurality of axes, the control signals resulting from a first transformation including a change of variable that enables dynamic decoupling between the control signals, along each of the axes of the plurality of axes; saturation of the control signals resulting from the first transformation to satisfy constraints of a battery fitted in the automobile and connected to the electric motor; and blockage of at least some of the current reference values of the regulation if the control signals are saturated.

9. A method for controlling a power train installed in a motor vehicle and including an electric motor including a rotor and a stator, the method comprising:
-
regulation of rotor and stator currents via control signals for the electric motor, the currents and the control signals being expressed in a revolving reference frame and including a plurality of axes, the control signals being derived from a first transformation including a change of variable allowing for dynamic decoupling between the control signals along each of the axes of the plurality of axes; saturation of the control signals obtained from the first transformation to satisfy constraints associated with a battery installed in the motor vehicle and connected to the electric motor; and blocking of at least some of regulation current setpoints if the control signals are saturated. - View Dependent Claims (10, 11, 12)

13. A system for controlling a power train installed in a motor vehicle and including an electric motor including a rotor and a stator, the system comprising:
-
means for regulating rotor and stator currents using control signals for the electric motor, the currents and the control signals being expressed in a revolving reference frame and including a plurality of axes, the control signals being obtained from a first transformation including a change of variable allowing for dynamic decoupling of the control signals along each of the axes of the plurality of axes; means for saturating the control signals obtained from the first transformation to satisfy constraints associated with a battery installed in the motor vehicle and connected to the electric motor; and a blocking means configured to perform blocking of at least some of current setpoints of the regulation means if the control signals are saturated. - View Dependent Claims (14, 15, 16)
