Title: VEHICLE PROPULSION SYSTEM
Abstract:
The propulsion system comprises: a heat engine (10), a transmission unit (12) for transmit¬ ting to the vehicle wheels the power supplied by the heat engine (10), an auxiliary power unit (14) for storing and/or supplying energy, a planetary gear set (16) interposed between the heat engine (10) and the transmission unit (12) and connected to the auxiliary power unit (12), a locking device (36) associated with the planetary gear set (16) and shiftable between a first position, wherein the auxiliary power unit (14) does not exchange power with the planetary gear set (16), and a second position, wherein the auxiliary power unit (14) exchanges power with the planetary gear set (16), and a braking device (40) which is interposed between the planetary gear set (16) and the heat engine (10) and is configured to modulate the motion resistance torque of the heat engine (10).
