PURPOSE:To automatically prevent rolling of a car by specifying a relation between a moment FH (F = centrifugal force, H = height of the center of gravity) and WDL (W = car total weight, DL = distance between the vertical surface against road surface and the center of gravity). CONSTITUTION:A load on a spring and a position in the horizontal direction of its center of gravity are calculated from a stationary load applied on four wheels of a car and the position of the spring, and the total load of the car and a position in the horizontal direction of its center of gravity. Additionally, a distance D between a flat surface vertical against the road surface and the center of gravity including outside grounding points P, P of outside wheels of the car circling (DL in the case of right circling and DR in the case of left circling) is calculated, and an expression V<2>>KRD/H is computed from a constant (k) and a linear velocity V determined in consideration of the turning circle R.g.H (g = gravitational velocity, H = height of the center of gravity of the car) gained from the angle of rotation of a steering wheel and a safety factor. The, in the case when this expression or an equivalent expression is realized, acceleration is automatically slackened or a safety measure such as alarming is taken. |
