Abstract
A heavy-duty vehicle including a movable arm, an operator control unit, an inertial measurement device, and a controller. The operator control unit directs movement of the movable arm. The inertial measurement device measures a pitch motion and a heave motion of the heavy-duty vehicle. The controller mitigates pitch motion and heave motion by adjusting a movement of the movable arm. The inertial measurement device detects a motion in one of a first direction and a second direction. The controller determines a direction of movement of the arm in one of a third direction and a fourth direction. The controller increases the speed of motion of the arm when the motion is in the first direction and the movement is in the third direction or when the motion is in the second direction and the movement is in the fourth direction.
