  • the current control is performed, so that the electromagnet actuator 42 engages the clutch 45 in the connecting piece 44.
  • the synchronization and the connection of the electric machine 23 with the wheels 27 has a duration of less than 600 ms.
  • the current consumption of the electromagnet must not be greater than 5A and preferably less than 2A when the uncoupling device 41 is in the locked state.
  • the device 41 comprises at least one sensor 46 able to return the position of the clutch 45 so that the control unit 31.2 can confirm the reconnection of the rotating electrical machine 23.
  • the locking device 48 comprises a latch 50 movable between an unlocked position in which the latch 50 is disengaged from the teeth of a pinion 51 of a shaft connected directly or indirectly to the wheels 27 (See Figure 4a) and a locked position in which the latch 50 is engaged with the teeth of the pinion 51 ( Figure 4b).
  • the blocking device 48 also includes sensors 52 necessary to guarantee the safety of its operation.
  • This electric machine 23 ' is associated with a power inverter 30'.
