A center-of-gravity detecting system (100) includes a motion detector (14) for detecting a vertical motion of a travelling object in a self-weight direction during travel and a horizontal motion of the travelling object in a widthwise direction during travel, and an arithmetic unit (15). The arithmetic unit (15) calculates a center-of-gravity location of the travelling object in the self-weight direction in a cross-section perpendicular to the travel direction of the travelling object and a center-of-gravity location of the travelling object in the widthwise direction in the cross-section perpendicular to the travel direction, using the frequency of a vertical motion of the travelling object in the self-weight direction, a frequency of the horizontal motion of the travelling object in the widthwise direction, a central angle of the horizontal motion of the travelling object in the widthwise direction, and the width of the traveling object. The arithmetic unit (15) calculates a center-of-gravity location of the travelling object in the travel direction, using the frequency of the vertical motion of the travelling object in the self-weight direction, a frequency of the horizontal motion of the travelling object in the travel direction, the center-of-gravity location of the travelling object in the self-weight direction, and the length of the travelling object in the travel direction. |
