CONTROLLER FOR CAR HEIGHT AND POSTURE IN MOBILE FARM WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To set the right side closer to an operator sitting in a mobile machine body at the side of the car height reference and stably carry out the tilted posture control while visually observing the car height by an operator and preventing the car height on the right side thereof from frequently lifting and lowering. SOLUTION: This controller is capable of initially changing the car height on the left side while holding the right car height HR0 as the reference side, controlling the posture so as to provide a prescribed tilt angleθx1, then changing the right car height which is the reference side to HR and providing a prescribed tilt angleθx2 when a prescribed tilt angleθx2 is not reached even if the car height on the right side is moved to the upper or the lower limit in the posture control, subsequently returning the right car height to HR0 once and then changing the car height on the left side again and performing the control so as to bring the tilt angle near to the desired tilt angle when changing the tilt angle and controlling the posture again.
