ABSTRACT

An apparatus for controllably moving a work implement is disclosed. The
implement is connected to a work machine and is moveable in response to
operation of a hydraulic cylinder. The apparatus includes an operator
controlled joystick. A joystick position sensor senses the position of the
joystick and responsively generates an operator command signal. Boom and
bucket angle sensors sense the position of the work implement and responsively
produces an boom angle signal and a bucket angle signal respectively. A
microprocessor based controller receives the boom angle, bucket angle, and
operator command signals, modifies the operator command signal, and produces
an electrical valve signal in response to the modified operator command
signal. An electrohydraulic valve receives the electrical valve signal, and
controllably provides hydraulic fluid flow to the hydraulic cylinder in
response to a magnitude of the electrical valve signal.
