CENTER-OF-GRAVITY DETECTING SYSTEM
First Claim
1. A center-of-gravity detecting system comprising:
- a motion detector for detecting a vertical motion of a travelling object in a self-weight direction of the travelling object during travel, and a horizontal motion of the travelling object in a widthwise direction of the travelling object during travel; and
an arithmetic unit;
wherein the arithmetic unit obtains a frequency of the vertical motion in the self-weight direction and a frequency of the horizontal motion in the widthwise direction corresponding to a width of the traveling object, by using the motion detector;
the arithmetic unit calculates a center-of-gravity location of the travelling object in the self-weight direction in a cross-section perpendicular to the travel direction 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 the vertical motion in the self-weight direction, the frequency of the horizontal motion in the widthwise direction, a central angle of the horizontal motion in the widthwise direction, and the width of the traveling object;
the arithmetic unit derives coefficients in a formula in which a relation between the width of the travelling object and the frequency of the horizontal motion in the widthwise direction is formulated, using the center-of-gravity location in the self-weight direction, the center-of-gravity in the widthwise direction, the frequency of the vertical motion in the self-weight direction, and the central angle of the horizontal motion in the widthwise direction;
the arithmetic unit calculates a frequency of the horizontal motion in the travel direction, using the coefficients in the formula, in a case where the width of the travelling object is a length of the travelling object in the travel direction, in the formula; and
the arithmetic unit calculates a center-of-gravity location of the travelling object in the travel direction, using the frequency of the vertical motion in the self-weight direction, a frequency of the horizontal motion in the travel direction, the center-of-gravity location in the self-weight direction, and the length of the travelling object in the travel direction.

Abstract
A center-of-gravity detecting system includes a motion detector for detecting a vertical motion of a travelling object and a horizontal motion of the travelling object and an arithmetic unit that calculates a center-of-gravity location of the travelling object using the frequency of a vertical motion of the travelling object, a frequency of the horizontal motion of the travelling object, a central angle of the horizontal motion of the travelling object, and the width of the traveling object. The arithmetic unit calculates a center-of-gravity location, using the frequency of the vertical motion, a frequency of the horizontal motion, the center-of-gravity location, and the length of the travelling object in the travel direction.
