A method of operating a dual purpose hybrid electric vehicle, the method comprising:
- providing a first mover for propelling the vehicle;
- providing a second mover;
- providing a third mover;
- physically engaging the first mover and a gear reduction with a main clutch;
- and
- physically disengaging the first mover and the gear reduction to direct power to a power split with a locking clutch coupled to the second and third movers, for at least one of:
- exporting power external to the vehicle, and
- activating a power take off device that is powered selectively by the second and third movers using the power split, wherein the power take off device includes a hydraulic pump.
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
- physically engaging the first mover and a gear reduction with a main clutch;
- sensing a condition for activating the first, second and third movers;
- physically disengaging the first mover from the gear reduction to direct power to a power split with a locking clutch coupled to the second and third movers, for at least one of:
- exporting power external to the vehicle, and
- activating the power take off device that is powered selectively by the second and third movers using the power split, wherein the power take off device includes a hydraulic pump.
