Roll prevention device for car

Abstract

Abstract PURPOSE:To prevent any roll of a car simply and surely by actuating a safety device automatically when fixed constants of distance, height and safety factor relating to the gravity of a vehicle, and quantitative relationship to normal acceleration satisfy a specified condition. CONSTITUTION:A speed obtained from a speed detecting mechanism 35 and a condition obtained from an inclination detecting mechanism 36 are input in an arithmetic unit 1 besides a load detected value. A specified value of each load is selected and input in an arithmetic unit 2 only when there is no input of speed and input of inclination. Also, the weight of a load under a spring and a position of its center of gravity are input in an arithmetic unit 3 by the setting mechanism 43-45. Further, the data centering a rotational angle of a handle detected by a rotational angle detecting mechanism 37 whether it is clockwise or counterclockwise is output from an arithmetic unit 4. When a distance D between a flat vertical to the road surface and including the external earth connecting point of the external wheel and its center of gravity, a height H of the center of gravity of the vehicle a fixed constant k, and a normal acceleration alphac from a speed detecting device 39 satisfy a formula alphac>kD/H by an arithmetic unit 7, a safety device is actuated automatically.
