The system includes at least one transmission belt (7) operable to couple the drive shafts (5a, 6a) of auxiliary devices (5, 6) with a pulley (8) operatively connectable to the crankshaft (2) of the internal combustion engine (3), and a servo controlled clutch (9, 10) operable selectively to control the coupling of the pulley (8) with the crankshaft (2) of the internal combustion engine (3). <??>Between the pulley (8) and the crankshaft (2) of the engine (3) is interposed an overrun clutch (11) such that when the angular velocity of the crankshaft (2) is greater than and, respectively, less than that of the pulley (8), the pulley (8) is able to be driven in rotation by the crankshaft (2) and, respectively, becomes freely rotatable with respect to this crankshaft (2). <??>The servo controlled clutch (9) is normally de energised and disengaged. <??>The system further includes control devices (ECU;12) for causing energisation and engagement of the servo controlled clutch (9, 10) and activation of the machine (6) as a motor, whilst the internal combustion engine (3) is not running, in order to restart the motor (3) by means of the electric machine (6) operating as a motor. <IMAGE> |
