Abstract
The present invention provides a method and apparatus for controlling a electro-hydraulic system of an earthmoving machine. The electro-hydraulic system may include a pump providing fluid to at least one fluid system. The electro-hydraulic system also includes an engine connected to the pump, and a controller for providing a commands to the engine. The method includes the steps of determining a desired characteristic of the fluid system, comparing the desired characteristic with a deliverable characteristic of the fluid system, and generating a power boost in response to the comparison; thereby controlling the electro-hydraulic system.
