A power unit for an automotive vehicle includes an internal combustion engine, an electric machine electrically connected to electrical power storage arrangement, and a turbocharger comprising a first turbine located in an exhaust line of the engine. This power unit further includes a second turbine
A power unit for an automotive vehicle includes an internal combustion engine, an electric machine electrically connected to electrical power storage arrangement, and a turbocharger comprising a first turbine located in an exhaust line of the engine. This power unit further includes a second turbine, located in an exhaust line of the engine and drivingly connected to the electric machine, and a transmission set. A first input/output of the transmission set is connected to the second turbine and a second input/output of the transmission set is connected to a crankshaft of the internal combustion engine. The transmission set has an adjustable speed reduction ratio between its first and second inputs/outputs.

1. A power unit for an automotive vehicle the unit comprising: an internal combustion engine,an electric machine electrically connected to an electrical power storage arrangement,a turbocharger comprising a first turbine located in an exhaust line of the engine,a second turbine located in an exhaust line of the engine, and drivingly connected to the electric machine, anda transmission set having a first input/output connected to the second turbine and a second input/output connected to a crankshaft of the internal combustion enginewherein the power transmission set is a triple input/output transmission set having a third input/output connected to the electric machine and has a speed reduction ratio between first and second inputs/outputs thereof that is adjustable by controlling the electric machine. 2. Power unit according to claim 1, wherein the triple input/output transmission set comprises an epicyclic gear train. 3. Power unit according to claim 2, wherein a sun of the sear train is coupled to the crankshaft. 4. Power unit according to claim 2, wherein a ring of the gear train is coupled to the crankshaft. 5. Power unit according to claim 2, wherein a satellite-carrier oldie gear train is coupled to the crankshaft. 6. Power unit according to claim 2, wherein a sun of the gear train is coupled to the turbine. 7. Power unit according to claim 2, wherein a ring of the gear train is coupled to the turbine. 8. Power unit according to claim 2, wherein a satellite carrier of the gear train is coupled to the turbine. 9. Power unit according to claim 1, wherein the electric machine can work as a generator or as a motor, depending on the working conditions of the power unit. 10. Power unit according to claim 1, wherein it also includes another electric machine electrically connected to the electrical power storage arrangement and coupled to the crankshaft independently of the triple input/output transmission set. 11. Power unit according to claim 10, wherein both electric machines can work as a generator or as a motor, depending on the working conditions of the power unit. 12. Power unit according to claim 1, wherein it also includes another electric machine electrically connected to the electrical power storage arrangement and mechanically coupled to the second turbine and to the first input/output of the transmission set. 13. Power unit according to claim 1, wherein it also includes another electric machine, electrically connected to the electrical power storage arrangement and mechanically coupled to a compressor (171) and to a turbine of the turbo charger. 14. An automotive vehicle including a power unit according to claim 1. 15. Power unit according to claim 1, comprising means for controlling the electric machine to adjust the speed reduction ratio between the first and second inputs/outputs to optimize working conditions of the second turbine and the internal combustion engine. 16. A power unit for an automotive vehicle the unit comprising: an internal combustion engine,an electric machine electrically connected to an electrical power storage arrangement,a turbocharger comprising a first turbine located in an exhaust line of the engine,a second turbine located in an exhaust line of the engine, and drivingly connected to the electric machine, anda transmission set having a first input/output connected to the second turbine and a second input/output connected to a crankshaft of the internal combustion engine, andanother electric machine electrically connected to the electrical power storage arrangement and coupled to the crankshaft independently of the triple input/output transmission set,wherein the power transmission set is a triple input/output transmission set having a third input/output connected to the electric machine and has a speed reduction ratio between first and second inputs/outputs thereof that is adjustable and the other electric machine can deliver, when it works as a motor, a maximum power which is higher than the maximum power which can be delivered by the electric machine connected to the second input/output of the transmission set.
