Stability control device of vehicle improved against hunting

摘要

A stability control device of a vehicle having an estimator for estimating a liability of the vehicle body to a turn running instability for producing an instability quantity which generally increases along with an increase of the liability; a brake system for selectively applying a variable braking force to each of the wheels; and a controller for controlling the brake system so as variably to apply a braking force to a selected one or ones of the wheels at a rate calculated based upon the instability quantity for suppressing the vehicle body against the turn running instability, wherein the controller sets a maximum possible value of the rate so that the maximum possible value being lowered along with increase of time of applying the braking force.
