Abstract

A plug-in hybrid electric vehicle system employs an improved integrated propulsion device, a drive system and battery management system that is operable to be used in the commercial vehicle business. The vehicle system is operable to provide optimal performance for particular fleet applications by taking into consideration driving patterns and load demands. The vehicle system also provides a drive for auxiliary equipment for work vehicles and driver selectable driving modes for when a vehicle encounters different driving demands.

Claims

1-12. -12. (canceled)

13. A system for operating a hybrid electric vehicle comprising:

a controller, a power take off device, a first mover, a second mover and a third mover;

the controller sensing a first condition for activating the first mover;

the controller sensing a second condition for activating the second and third movers; and

the controller operable to direct power from one of said movers to activate the power take off device.

14. The system for operating a hybrid electric vehicle as claimed in claim 13, further comprising an accessory driven by the power take off device.

15. The system for operating a hybrid electric vehicle as claimed in claim 13, further comprising a rechargeable battery system for storing energy that can provide power on demand.

16. The system for operating a hybrid electric vehicle as claimed in claim 13, further comprising a control panel and a power outlet for delivering utility grade power external to the system.

17. The system for operating a hybrid electric vehicle as claimed in claim 13, further comprising a continuous fueling feature that allows an external energy supply to propel one of said movers.

18. The system for operating a hybrid electric vehicle as claimed in claim 13, wherein the system is operable to propel a vehicle down the road, and then allow the vehicle to be used in another instance to generate power that is at least one of exported from the vehicle and used for the power take off device to run an accessory.

19. The system for operating a hybrid electric vehicle as claimed in claim 13, wherein the movers may operate in different modes based on predetermined conditions.

20. A method of operating a dual purpose hybrid electric vehicle, the method comprising:

providing a first mover propelling the vehicle;

providing a second mover operating a power take off device; and

providing a third mover for at least one of;

exporting power external to the vehicle, and

activating a power take off device.

21. The method of claim 20, further comprising providing an export power conditioner for the exporting power, from the third mover, external to the vehicle.

22. The method of claim 20, wherein the power take off device, powered by the third mover, includes a hydraulic pump for tools or equipment.

23. The method of claim 20, further comprising providing a continuous fueling feature for an external energy supply to propel at least one of the first, second and third movers.

24. The method of claim 20, further comprising using power generated from propelling the vehicle along a road for the at least one of exporting power external to the vehicle and activating the power take off device.

25. The method of claim 20, further comprising providing an interlock that is in communication with a control member, wherein the interlock is configured to prevent propelling of the vehicle while it is connected to an energy source external to the vehicle.

26. A method of operating a vehicle, the method comprising:

providing a controller, a power take off device, a first mover, a second mover, and a third mover, at least one of the movers coupled to a gear reduction with a clutch;

sensing a condition for activating the first, second and third movers; and

disengaging the at least one of the first, second and third movers from the gear reduction to direct power from the at least one of the movers for at least one of;

exporting power external to the vehicle, and

activating a power take off device.

27. The method of claim 26, further comprising providing an export power conditioner for the exporting power, from the at least one the first, second and third movers, external to the vehicle.

28. The method of claim 26, wherein the power take off device, powered the at least one the first, second and third movers, includes a hydraulic pump for tools or equipment.

29. The method of claim 26, further comprising providing a continuous fueling feature for an external energy supply to propel at least one of the first, second and third movers.

30. The method of claim 26, further comprising driving, with the power take off device, an accessory device including a hydraulic pump.

31. The method of claim 26, further comprising using power generated from propelling a vehicle along a road for the at least one of exporting power external to the vehicle and activating the power take off device.

32. The method of claim 26, further comprising preventing, with an interlock in communication with a control member, propelling of the vehicle while connected to an energy source external to the vehicle.
