1. A vehicle dynamic control system comprising:

  • a running condition detecting means for detecting running conditions of a vehicle;

    a road data detecting means for detecting road data relating to a road in front of the vehicle;

    a worth judging distance calculating means for calculating a worth judging distance from a point of operation to a curve on the road in front of the vehicle based on said road data, said worth judging distance being corrected and reduced according to a curvature of a winding part of the road between said point of operation and the curve, wherein said worth judging distance calculating means includes equivalent linear distance calculating means responsive to a coefficient signal relating to road friction characteristics, said road data, and a warning deceleration threshold level, said equivalent linear distance calculating means for deriving a linear distance equivalent to a shortened distance of the curve and for generating a linear distance signal which is provided to the passing judgement means;

    a passing judgement means for judging a possibility of the vehicle passing through the curve based on said worth judging distance calculated by said worth judging distance calculating means; and

    a warning and deceleration control means for activating at least one of a warning means and a decelerating means based on a judgement of said passing judgement means.
