Abstract
A vehicle dynamic control system includes: (a) a running condition detecting system for detecting running conditions of a vehicle; (b) a road data detecting system for detecting road data relating to a road in front of the vehicle; (c) a permissible speed calculating system for calculating a permissible speed for passing through a curve based on the running conditions and the road data; (d) an equivalent linear distance calculating system for calculating an equivalent linear distance as a distance for performing a deceleration operation by shortening a distance from a point of operation to the curve in front of the vehicle based on a permissible deceleration at a winding part of the road and a curvature of the winding part between the point of operation and the curve so as to consider a permissible deceleration applicable at the winding part of the road; (e) a passing judgement system for judging a possibility of the vehicle passing through the curve by a parameter based on at least the equivalent linear distance and the permissible speed; and (f) a warning and deceleration control system for activating at least one of a warning system or a decelerating system based on a judgement …
