1. A vehicle dynamic control system, comprising:

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

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

    permissible speed calculating means for calculating a permissible speed to pass through a curve based on said running conditions and said road data;

    equivalent linear distance calculating means for calculating an equivalent linear distance as a distance for performing a decelerating operation by shortening a distance from a point of said decelerating operation to the curve in front of the vehicle based on a permissible deceleration at a winding pale and a curvature of the winding part between the point of said decelerating operation and the curve so as to consider said permissible deceleration applicable at winding part of the road;

    passing judgement means for judging possibility of the vehicle passing through the curve by a parameter based on at least said equivalent linear distance and said permissible speed; and

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