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.

Abstract: Apparatus for preventing a vehicle from overturning on a curve due to a too high speed. First and second signals are produced, respectively, in proportion to the square root of the vehicle speed and in proportion to the sine of the steering angle. The first and second voltages are summed and amplified to produce a third signal. The third is compared with a reference voltage and fourth signal is produced if the third signal exceeds the reference voltage. An operational parameter of the vehicle such as the required force to operate the power steering unit or the fuel flow rate to the carburetor is varied to prevent overturn.
