ABSTRACT:
An electrohydraulic control system for loading a bucket of a work machine includes sensors for producing signals representative of bucket position and forces. A command signal generator receives the signals and calculates a target angle on the basis of accumulated energy, and a force vector angle representing actual forces produced at an reference point on the bucket. Lift and tilt command signals are modified in response to differences between the target and actual angles, and used to controllably extend the lift cylinder to raise the bucket through the material, while racking the bucket at rates calculated to efficiently capture the material.
