Abstract
A control method and system to control a pair of electric motors driving a vehicle. The steps provided for are: determining, in a control cycle N and by means of a first processing core, for a first electric motor, a first electric current target based on a first torque or speed target; determining, in the control cycle N and by means of a second processing core, for a second electric motor, a second electric current target based on a second torque or speed target; controlling, in the control cycle N and by means of the first processing core, a first electronic power converter connected to the first electric motor so as to pursue the first electric current target; and controlling, in the control cycle N and by means of the second processing core, a second electronic power converter connected to the second electric motor so as to pursue the second electric current target.
