Hybrid vehicle comprising: a first reversible electric machine (2), controlled through a first power converter (20), connected to the drive wheels (4) by means of transmission means (5); a group of batteries (19) for storing electrical energy; a second reversible electric machine (6) controlled as a generator through a second power converter (21) and coupled to the first electric machine (2), by means of first engagement means (7); an internal combustion engine (12) couplable to the second reversible electric machine (6), by means of second engagement means (13). In a nominal traction condition, the first converter transforms a first direct current of the battery group into a first controlled current, with which it sets the first electric motor in rotation; in a high electric power traction condition, the second converter transforms a second direct current of the battery group into a second controlled current, with which it sets the reversible machine in rotation as a second motor mechanically coupled with the first and decoupled from the combustion engine in order to increase the traction torque of the vehicle; in an on-board recharging condition, the second converter transforms a first variable current of the reversible machine, operating as a generator, mechanically coupled to the combustion engine and decoupled from the first electric motor, into a first rectified direct current for charging the storage group. |
