Abstract
A system for preventing a vehicle from turning sideways comprises a unit for measuring the weight of a cargo on the vehicle, a unit for measuring the height of gravitational center of the cargo on the vehicle, a unit for measuring the steering angle of the vehicle, and a unit for measuring the running speed of the vehicle. The static stability of the vehicle is derived from the weight and the height of gravitational center of the vehicle and the measured weight and height of gravitational center of the cargo. The dynamic instability of the vehicle during turning is derived from the measured steering angle and running speed. First and second allowable limits are determined according to the static stability. When the dynamic instability exceeds the first allowable limit, the clutch of the vehicle is disengaged, and when the instability exceeds the second limit, the vehicle is braked. Upon the dynamic instability exceeding each allowable limit, information to that effect is given.
