DYNAMIC STABILIZATION CONTROL OF EARTHMOVING MACHINE

PROBLEM TO BE SOLVED: To provide an earthmoving machine including a control system. SOLUTION: The machine is provided with a first and second satellite antennas installed in the longitudinal direction on the machine. A third satellite navigation antenna is attached to a pole installed on an operation element of the earthmoving machine. In one embodiment, the earthmoving machine is a bulldozer, and the operation element is a blade of the bulldozer. The machine further includes a gravity reference sensor and a plurality of gyroscopes installed on the machine. A computer processor produces a control signal on the basis of data received from various component parts. On the basis of the system and the method disclosed, the earthmoving machine can perform dynamically stable operation at a relatively high speed without developing undesired vibrations.
