Abstract
Systems and methods for improving operation of a power take off are presented. In one example, the power take off may be rotated in two different directions. The approaches may improve operation of a power take off device.
Claims20
A method of operating a vehicle, comprising:
- while the vehicle is stationary and parked, operating a power take off (PTO), including rotating a PTO output via rotating a first PTO power source in a first direction and a second direction;
- and rotating the PTO output via a positive torque provided by the first PTO power source and a positive torque provided by a second PTO power source.
A method of operating a power take off (PTO) of a vehicle, comprising:
- rotating a mechanical device external the vehicle and other than vehicle wheels via a PTO output by way of rotating a first PTO power source including an engine and a second PTO power source, the first PTO power source and the second PTO power source providing positive torque to a vehicle driveline;
- varying output of the first PTO power source and the second PTO power source in response to available output of the second PTO power source;
- and
- selectively shutting down the engine during stopped vehicle conditions.

A method for a vehicle, comprising:
- rotating a device external the vehicle and different than vehicle wheels via rotating a power take off (PTO) output by way of rotating an electric machine in a first direction;
- reversing rotation of the PTO output via rotating the electric machine in a second direction different than the first direction, the electric machine positioned in a vehicle driveline;
- and
- selecting shutting down the engine during stopped vehicle conditions.
