Patent Images
1. A center-of-gravity detection system comprising:
- a vehicle capable of carrying cargo and 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 vehicle during travel of said towed vehicle; and
an arithmetic unit;
wherein based upon physical quantities that correlate with the shakes, the arithmetic unit is configured to derive the location of the center of gravity, in three-dimensional space, of said towed vehicle.

Abstract
A center-of-gravity detection system includes a vehicle capable of carrying cargo and 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 the towed vehicle during travel of the towed vehicle, and an arithmetic unit. The arithmetic unit is configured to derive, based upon physical quantities that correlate with the shakes, the location of the center of gravity, in three-dimensional space, of the towed vehicle.

8. A lateral rollover limit velocity estimation system comprising:
-
a vehicle capable of carrying cargo and adapted to be towed by a towing vehicle; and an arithmetic unit; wherein the arithmetic unit is configured to obtain the location of the center of gravity, in three-dimensional space, of said towed vehicle and the curvature radius of a curved road section along which said towed vehicle travels and to derive a lateral rollover limit velocity for the curved road section in response to the obtained curvature radius with the use of the obtained location of the center of gravity. - View Dependent Claims (9, 10, 11, 12)

13. A cargo weight estimation system comprising:
-
a vehicle capable of carrying cargo and adapted to be towed by a towing vehicle; and an arithmetic unit; wherein said arithmetic unit is configured to obtain the location of the center of gravity, in three-dimensional space, of said towed vehicle loaded with the cargo and the location of center of gravity, in three-dimensional space, of said towed vehicle without the cargo and to derive the weight of the cargo with the use of the obtained two center-of-gravity locations. - View Dependent Claims (14, 15, 16)
