Adaptive drive control for milling machine

摘要

An adaptive advance system for a construction machine (10) senses the reaction forces applied by the ground surface (14) to a milling drum (12), and in response to the sensed changes in those reaction forces controls the motive power applied to an advance drive (40,42) of the machine (10) or the slowing of a rate of lowering the rotating milling drum (12). Early and rapid detection of such changes in reaction forces allow the control system to aid in preventing lurch forward events or the lurch forward or backward events respectively of the construction machine (10).
