Abstract

A hybrid vehicle includes an engine drivingly connected to a first pair of drive wheels by a transmission. A first motor generator is coupled to the engine to provide drive torque to the transmission for driving the first pair of drive wheels. A second motor generator is drivingly connected to a flywheel by a planetary gear system. The planetary gear system is connected to a second pair of drive wheels.

Claims (26)

1. A hybrid vehicle, comprising:

an engine drivingly connected to a first pair of drive wheels by a transmission;

a first motor generator coupled to the engine to provide drive torque to the transmission for driving the first pair of drive wheels;

a second motor generator drivingly connected to a flywheel by a planetary gear system, said planetary gear system connected to a second pair of drive wheels, wherein said planetary gear system includes a plurality of components, said second motor generator being connected to a first of said plurality of components, said flywheel connected to a second of said plurality of components and said second pair of drive wheels connected to a third of said plurality of components, wherein said planetary gear system includes a first brake directly connected to said first of said plurality of components.

2. The hybrid vehicle according to claim 1 , wherein said first of said plurality of components is a ring gear.

3. The hybrid vehicle according to claim 1 , wherein said second of said plurality of components is a sun gear.

4. The hybrid vehicle according to claim 1 , wherein said third of said plurality of components is a planetary carrier.

5. The hybrid vehicle according to claim 1 , wherein said planetary gear system is connected to said second pair of drive wheels by at least one gear pair.

6. A hybrid vehicle, comprising:

an engine drivingly connected to a first pair of drive wheels by a transmission;

a first motor generator coupled to the engine to provide drive torque to the transmission for driving the first pair of drive wheels;

a second motor generator drivingly connected to a flywheel by a planetary gear system, said planetary gear system connected to a second pair of drive wheels, wherein said planetary gear system includes a plurality of components, said second motor generator being connected to a first of said plurality of components, said flywheel connected to a second of said plurality of components and said second pair of drive wheels connected to a third of said plurality of components, wherein said planetary gear system includes a first brake connected to said first of said plurality of components, wherein said planetary gear system includes a second brake connected to said third of said plurality of components.

7. The hybrid vehicle according to claim 1 , wherein said planetary gear system is connected to said second pair of drive wheels by a plurality of gear pairs each having a clutch for providing a selective engagement for driving said second pair of drive wheels.

8. A hybrid vehicle, comprising:

an engine drivingly connected to a first pair of drive wheels by a transmission;

a first motor generator coupled to the engine to provide drive torque to the transmission for driving the first pair of drive wheels;

a second motor generator drivingly connected to a flywheel by a planetary gear system, said planetary gear system connected to a second pair of drive wheels, wherein said planetary gear system includes a plurality of components including a ring gear, a sun gear and a planetary carrier, said second motor generator being connected to a first of said plurality of components, said flywheel connected to a second of said plurality of components and said second pair of drive wheels connected to a third of said plurality of components, wherein said planetary gear system includes a first brake directly connected to said first of said plurality of components.

9. The hybrid vehicle according to claim 8 , wherein said first of said plurality of components is the ring gear.

10. The hybrid vehicle according to claim 8 , wherein said second of said plurality of components is the sun gear.

11. The hybrid vehicle according to claim 8 , wherein said third of said plurality of components is the planetary carrier.

12. The hybrid vehicle according to claim 8 , wherein said planetary gear system is connected to said second pair of drive wheels by at least one gear pair.

13. A hybrid vehicle, comprising:

an engine drivingly connected to a first pair of drive wheels by a transmission;

a first motor generator coupled to the engine to provide drive torque to the transmission for driving the first pair of drive wheels;

a second motor generator drivingly connected to a flywheel by a planetary gear system, said planetary gear system connected to a second pair of drive wheels, wherein said planetary gear system includes a plurality of components including a ring gear, a sun gear and a planetary carrier, said second motor generator being connected to a first of said plurality of components, said flywheel connected to a second of said plurality of components and said second pair of drive wheels connected to a third of said plurality of components, wherein said planetary gear system includes a first brake connected to said first of said plurality of components, wherein said planetary gear system includes a second brake connected to said third of said plurality of components.

14. The hybrid vehicle according to claim 8 , wherein said planetary gear system is connected to said second pair of drive wheels by a plurality of gear pairs each having a clutch for providing a selective engagement for driving said second pair of drive wheels.
