Abstract
A power take-off system and method is provided for a vehicle that includes an internal combustion engine, an electrical generator, an electrical machine, a power take-off summing planetary and a power take-off brake. The power take-off system includes a controller and a human-machine interface. The controller is configured to receive an input from the human-machine interface to select one of a variable speed power take-off mode, an electrical power generation mode, and a full power fixed ratio power take-off mode of operation. In the variable speed power take-off mode, electrical power from the electrical generator and rotational power by the power take-off system are output, and the electrical machine receives electricity and provides rotational power. In the electrical power generation mode, the electrical generator and the electrical machine both provide electrical power. In the full power fixed ratio mode, no electrical power is provided.
