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. A plug-in hybrid electric vehicle system comprising:

an internal combustion engine;

an integrated propulsion device that receives input from the internal combustion engine, the integrated propulsion device including a first electric machine and a second electric machine; and

an output for providing power to an output shaft.

2. The vehicle as claimed in claim 1, further comprising a driver selectable drive mode module for allowing a driver to directly choose or bias the selection of the real time driving mode.

3. The vehicle as claimed in claim 1, further comprising an exportable power generation system.

4. The vehicle as claimed in claim 1, further comprising a load sensing adaptive control.

5. The vehicle as claimed in claim 1, further comprising a data logging system for gathering battery usage and operating environment conditions over time data.

6. The vehicle as claimed in claim 1, further comprising an auxiliary equipment drive system.

7. The vehicle as claimed in claim 1, further comprising an accessory that is operable to be driven by a PTO.

8. The vehicle as claimed in claim 1, further comprising a hybrid control that is in communication with the internal combustion engine and the integrated propulsion device for controlling the delivery of power to the output shaft.

9. The vehicle as claimed in claim 1, further comprising a continuous energy source that is external to the vehicle, the continuous energy source is connected to the vehicle via a connector and permits the vehicle to operate for extended periods.

10. The vehicle as claimed in claim 1, further comprising an interlock that is in communication with a control member, the interlock is operable to prevent the vehicle from moving while it is connected to an energy source.

11. The vehicle as claimed in claim 1, further comprising a gear reducer.

12. The vehicle as claimed in claim 1, further comprising an export power conditioner that permits the vehicle to export power external the vehicle.

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

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

the controller sensing a condition for activating the first mover;

the controller sensing a 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 this 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 to in another instance to generate power that may be exported from the vehicle and/or used for a 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 comprising the steps of a first mover propelling the vehicle, a second mover operating a power take off device, and a third mover for exporting power external to the vehicle to a grid.
