Abstract
A system and method for controlling automatic leveling heavy construction equipment. The system has a lower frame and an upper frame, the lower frame having a traveling unit, and the upper frame being tiltably and swingably connected to the lower frame. The system comprises a sensor unit, provided in the equipment, including an inclination detecting sensor for measuring twist angles of the lower frame and the upper frame against a reference horizontal surface, a traveling detection sensor for measuring a traveling speed of the equipment, and a working device sensor for detecting working state information of a working device. A control unit receives the twist angles, the traveling speed, and the working state information, calculates a corrected angle at which the upper frame is to be tilted against the lower frame, and generates a control signal for instructing an operation of an actuator. A driving unit performs a leveling control through the actuator in accordance with the received control signal.
