Abstract:
A method of controlling an electro-hydraulic system of an earthmoving machine, the electro-hydraulic fluid system including a pump providing fluid to at least one fluid system, an engine connected to the pump, the engine providing power to the pump, at least one parasitic load connected to said engine, and a controller configured to provide a command to the engine, comprising the steps of:determining a desired characteristic of said fluid system;comparing said desired characteristic with a deliverable characteristic of said fluid system; andgenerating a power boost in response to said desired characteristic being greater than said deliverable characteristic and one of delivering a power boost command to said engine and disabling at least one of said at least one parasitic load from said engine; thereby increasing said deliverable characteristic in response to said power boost and controlling the fluid system.
