Abstract
A method is provided for controlling an electric drive work machine including an engine and an electric motor that provides power to enable the work machine to travel across a surface terrain at certain ground speeds. In one embodiment, the method may include detecting a reverse directional shift of the work machine causing the work machine to travel in a reverse direction. Further, the method may include performing an engine speed reduction process that reduces a current speed of the engine based on the detected reverse directional shift without reducing a ground speed of the work machine while traveling in the reverse direction.
