<p>The system (CVT) comprises: a first rotor (R1) provided with a multiphase winding (W1) and fixed firmly to the shaft (1) of the internal combustion engine (ICE) and a second intermediate coaxial rotor (R2) operatively cooperating with the first rotor (R1) and coupled with at least one axle (2) of the motor vehicle, and a stator (ST), arranged on the opposite side of the intermediate rotor (R2), provided with a multiphase winding (W2), and operatively cooperating with the intermediate rotor (R2), a first inverter and a second inverter (I1, I2) connected to the rotor (R1) and the stator (ST), respectively, and connected in parallel with one another by means of a d.c. voltage link (L), sensors (S1-Sn) suitable for providing signals indicative of the operating conditions of the internal combustion engine (ICE) and of the motor vehicle, and an electronic control unit (ECU) arranged to control the operation of the inverters (I2, I2) in a manner such that, after the engine (ICE) has been started, the voltage (Vdc) in the d.c. voltage link (L) is regulated to a predetermined value which is variable in dependence on the values of the parameters monitored by the sensors (S1-Sn). </p> |
