Stability control device of vehicle improved against hunting
First Claim
1. A stability control device of a vehicle having a vehicle body, and front left, front right, rear left and rear right wheels, comprising:
- a means for estimating a liability of the vehicle body to a turn running instability for producing an instability quantity which generally increases along with increase of said liability;
a brake means for selectively applying a variable braking force to each of said wheels; and
a control means for controlling said brake means so as variably to apply a braking force to a selected one or ones of said wheels at a rate calculated based upon said instability quantity for suppressing the vehicle body against said turn running instability;
wherein said control means sets a maximum possible value of said rate so that the maximum possible value is lowered along with increase of time of applying the braking force.

Abstract
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.
