Abstract:
1. A center-of-gravity detection system comprising: a container cargo vehicle comprising a container capable of carrying cargo and a container chassis upon which the container is placed, the container cargo vehicle adapted to be towed by a towing vehicle; a shake detector configured to detect shakes in the directions of the self-weight and width of said towed container cargo vehicle during travel of said towed container cargo vehicle; and an arithmetic unit; wherein when the shake in the self-weight direction corresponds to a vertical reciprocation motion in which a center of gravity of said container cargo vehicle is a mass point and the shake in a width direction corresponds to a horizontal simple pendulum motion in which an axle center of said container cargo vehicle is a support point and a center of gravity of said container cargo vehicle is a mass point; said arithmetic unit is configured to derive, based upon the frequency of the simple pendulum motion, the location of the center of gravity of said container cargo vehicle with respect to the travel direction of said container, and to further derive, based upon the frequency of the reciprocation motion, the frequency of the simple pendulum motion, and the central angle of the simple pendulum motion, the location of the center of gravity of said container cargo vehicle with respect to a cross-section surface perpendicular to the travel direction of said container.
